5 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
6
7 *) Fix cipher selection routines: ciphers without encryption had no flags
8 for the cipher strength set and where therefore not handled correctly
9 by the selection routines (PR #130).
10 [Lutz Jaenicke]
11
12 *) Fix EVP_dsa_sha macro.
13 [Nils Larsch]
14
15 *) New option
16 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
17 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
18 that was added in OpenSSL 0.9.6d.
19
20 As the countermeasure turned out to be incompatible with some
21 broken SSL implementations, the new option is part of SSL_OP_ALL.
22 SSL_OP_ALL is usually employed when compatibility with weird SSL
23 implementations is desired (e.g. '-bugs' option to 's_client' and
24 's_server'), so the new option is automatically set in many
25 applications.
26 [Bodo Moeller]
27
28 *) Changes in security patch:
29
30 Changes marked "(CHATS)" were sponsored by the Defense Advanced
31 Research Projects Agency (DARPA) and Air Force Research Laboratory,
32 Air Force Materiel Command, USAF, under agreement number
33 F30602-01-2-0537.
34
35 *) Add various sanity checks to asn1_get_length() to reject
36 the ASN1 length bytes if they exceed sizeof(long), will appear
37 negative or the content length exceeds the length of the
38 supplied buffer.
39 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
40
41 *) Assertions for various potential buffer overflows, not known to
42 happen in practice.
43 [Ben Laurie (CHATS)]
44
45 *) Various temporary buffers to hold ASCII versions of integers were
46 too small for 64 bit platforms. (CAN-2002-0655)
47 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
48
49 *) Remote buffer overflow in SSL3 protocol - an attacker could
50 supply an oversized session ID to a client. (CAN-2002-0656)
51 [Ben Laurie (CHATS)]
52
53 *) Remote buffer overflow in SSL2 protocol - an attacker could
54 supply an oversized client master key. (CAN-2002-0656)
55 [Ben Laurie (CHATS)]
56
57 Changes between 0.9.6c and 0.9.6d [9 May 2002]
58
59 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
60 encoded as NULL) with id-dsa-with-sha1.
61 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
62
63 *) Check various X509_...() return values in apps/req.c.
64 [Nils Larsch <nla@trustcenter.de>]
65
66 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
67 an end-of-file condition would erronously be flagged, when the CRLF
68 was just at the end of a processed block. The bug was discovered when
69 processing data through a buffering memory BIO handing the data to a
70 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
71 <ptsekov@syntrex.com> and Nedelcho Stanev.
72 [Lutz Jaenicke]
73
74 *) Implement a countermeasure against a vulnerability recently found
75 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
76 before application data chunks to avoid the use of known IVs
77 with data potentially chosen by the attacker.
78 [Bodo Moeller]
79
80 *) Fix length checks in ssl3_get_client_hello().
81 [Bodo Moeller]
82
83 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
84 to prevent ssl3_read_internal() from incorrectly assuming that
85 ssl3_read_bytes() found application data while handshake
86 processing was enabled when in fact s->s3->in_read_app_data was
87 merely automatically cleared during the initial handshake.
88 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
89
90 *) Fix object definitions for Private and Enterprise: they were not
91 recognized in their shortname (=lowercase) representation. Extend
92 obj_dat.pl to issue an error when using undefined keywords instead
93 of silently ignoring the problem (Svenning Sorensen
94 <sss@sss.dnsalias.net>).
95 [Lutz Jaenicke]
96
97 *) Fix DH_generate_parameters() so that it works for 'non-standard'
98 generators, i.e. generators other than 2 and 5. (Previously, the
99 code did not properly initialise the 'add' and 'rem' values to
100 BN_generate_prime().)
101
102 In the new general case, we do not insist that 'generator' is
103 actually a primitive root: This requirement is rather pointless;
104 a generator of the order-q subgroup is just as good, if not
105 better.
106 [Bodo Moeller]
107
108 *) Map new X509 verification errors to alerts. Discovered and submitted by
109 Tom Wu <tom@arcot.com>.
110 [Lutz Jaenicke]
111
112 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
113 returning non-zero before the data has been completely received
114 when using non-blocking I/O.
115 [Bodo Moeller; problem pointed out by John Hughes]
116
117 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
118 [Ben Laurie, Lutz Jaenicke]
119
120 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
121 Yoram Zahavi <YoramZ@gilian.com>).
122 [Lutz Jaenicke]
123
124 *) Add information about CygWin 1.3 and on, and preserve proper
125 configuration for the versions before that.
126 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
127
128 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
129 check whether we deal with a copy of a session and do not delete from
130 the cache in this case. Problem reported by "Izhar Shoshani Levi"
131 <izhar@checkpoint.com>.
132 [Lutz Jaenicke]
133
134 *) Do not store session data into the internal session cache, if it
135 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
136 flag is set). Proposed by Aslam <aslam@funk.com>.
137 [Lutz Jaenicke]
138
139 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
140 value is 0.
141 [Richard Levitte]
142
143 *) [In 0.9.6c-engine release:]
144 Fix a crashbug and a logic bug in hwcrhk_load_pubkey()
145 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
146
147 *) Add the configuration target linux-s390x.
148 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
149
150 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
151 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
152 variable as an indication that a ClientHello message has been
153 received. As the flag value will be lost between multiple
154 invocations of ssl3_accept when using non-blocking I/O, the
155 function may not be aware that a handshake has actually taken
156 place, thus preventing a new session from being added to the
157 session cache.
158
159 To avoid this problem, we now set s->new_session to 2 instead of
160 using a local variable.
161 [Lutz Jaenicke, Bodo Moeller]
162
163 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
164 if the SSL_R_LENGTH_MISMATCH error is detected.
165 [Geoff Thorpe, Bodo Moeller]
166
167 *) New 'shared_ldflag' column in Configure platform table.
168 [Richard Levitte]
169
170 *) Fix EVP_CIPHER_mode macro.
171 ["Dan S. Camper" <dan@bti.net>]
172
173 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
174 type, we must throw them away by setting rr->length to 0.
175 [D P Chang <dpc@qualys.com>]
176
177 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
178
179 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
180 <Dominikus.Scherkl@biodata.com>. (The previous implementation
181 worked incorrectly for those cases where range = 10..._2 and
182 3*range is two bits longer than range.)
183 [Bodo Moeller]
184
185 *) Only add signing time to PKCS7 structures if it is not already
186 present.
187 [Steve Henson]
188
189 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
190 OBJ_ld_ce should be OBJ_id_ce.
191 Also some ip-pda OIDs in crypto/objects/objects.txt were
192 incorrect (cf. RFC 3039).
193 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
194
195 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
196 returns early because it has nothing to do.
197 [Andy Schneider <andy.schneider@bjss.co.uk>]
198
199 *) [In 0.9.6c-engine release:]
200 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
201 [Andy Schneider <andy.schneider@bjss.co.uk>]
202
203 *) [In 0.9.6c-engine release:]
204 Add support for Cryptographic Appliance's keyserver technology.
205 (Use engine 'keyclient')
206 [Cryptographic Appliances and Geoff Thorpe]
207
208 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
209 is called via tools/c89.sh because arguments have to be
210 rearranged (all '-L' options must appear before the first object
211 modules).
212 [Richard Shapiro <rshapiro@abinitio.com>]
213
214 *) [In 0.9.6c-engine release:]
215 Add support for Broadcom crypto accelerator cards, backported
216 from 0.9.7.
217 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
218
219 *) [In 0.9.6c-engine release:]
220 Add support for SureWare crypto accelerator cards from
221 Baltimore Technologies. (Use engine 'sureware')
222 [Baltimore Technologies and Mark Cox]
223
224 *) [In 0.9.6c-engine release:]
225 Add support for crypto accelerator cards from Accelerated
226 Encryption Processing, www.aep.ie. (Use engine 'aep')
227 [AEP Inc. and Mark Cox]
228
229 *) Add a configuration entry for gcc on UnixWare.
230 [Gary Benson <gbenson@redhat.com>]
231
232 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
233 messages are stored in a single piece (fixed-length part and
234 variable-length part combined) and fix various bugs found on the way.
235 [Bodo Moeller]
236
237 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
238 instead. BIO_gethostbyname() does not know what timeouts are
239 appropriate, so entries would stay in cache even when they have
240 become invalid.
241 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
242
243 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
244 faced with a pathologically small ClientHello fragment that does
245 not contain client_version: Instead of aborting with an error,
246 simply choose the highest available protocol version (i.e.,
247 TLS 1.0 unless it is disabled). In practice, ClientHello
248 messages are never sent like this, but this change gives us
249 strictly correct behaviour at least for TLS.
250 [Bodo Moeller]
251
252 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
253 never resets s->method to s->ctx->method when called from within
254 one of the SSL handshake functions.
255 [Bodo Moeller; problem pointed out by Niko Baric]
256
257 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
258 (sent using the client's version number) if client_version is
259 smaller than the protocol version in use. Also change
260 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
261 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
262 the client will at least see that alert.
263 [Bodo Moeller]
264
265 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
266 correctly.
267 [Bodo Moeller]
268
269 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
270 client receives HelloRequest while in a handshake.
271 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
272
273 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
274 should end in 'break', not 'goto end' which circuments various
275 cleanups done in state SSL_ST_OK. But session related stuff
276 must be disabled for SSL_ST_OK in the case that we just sent a
277 HelloRequest.
278
279 Also avoid some overhead by not calling ssl_init_wbio_buffer()
280 before just sending a HelloRequest.
281 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
282
283 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
284 reveal whether illegal block cipher padding was found or a MAC
285 verification error occured. (Neither SSLerr() codes nor alerts
286 are directly visible to potential attackers, but the information
287 may leak via logfiles.)
288
289 Similar changes are not required for the SSL 2.0 implementation
290 because the number of padding bytes is sent in clear for SSL 2.0,
291 and the extra bytes are just ignored. However ssl/s2_pkt.c
292 failed to verify that the purported number of padding bytes is in
293 the legal range.
294 [Bodo Moeller]
295
296 *) Add OpenUNIX-8 support including shared libraries
297 (Boyd Lynn Gerber <gerberb@zenez.com>).
298 [Lutz Jaenicke]
299
300 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
301 'wristwatch attack' using huge encoding parameters (cf.
302 James H. Manger's CRYPTO 2001 paper). Note that the
303 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
304 encoding parameters and hence was not vulnerable.
305 [Bodo Moeller]
306
307 *) BN_sqr() bug fix.
308 [Ulf M�ller, reported by Jim Ellis <jim.ellis@cavium.com>]
309
310 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
311 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
312 followed by modular reduction.
313 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
314
315 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
316 equivalent based on BN_pseudo_rand() instead of BN_rand().
317 [Bodo Moeller]
318
319 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
320 This function was broken, as the check for a new client hello message
321 to handle SGC did not allow these large messages.
322 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
323 [Lutz Jaenicke]
324
325 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
326 [Lutz Jaenicke]
327
328 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
329 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
330 [Lutz Jaenicke]
331
332 *) Rework the configuration and shared library support for Tru64 Unix.
333 The configuration part makes use of modern compiler features and
334 still retains old compiler behavior for those that run older versions
335 of the OS. The shared library support part includes a variant that
336 uses the RPATH feature, and is available through the special
337 configuration target "alpha-cc-rpath", which will never be selected
338 automatically.
339 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
340
341 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
342 with the same message size as in ssl3_get_certificate_request().
343 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
344 messages might inadvertently be reject as too long.
345 [Petr Lampa <lampa@fee.vutbr.cz>]
346
347 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
348 [Andy Polyakov]
349
350 *) Modified SSL library such that the verify_callback that has been set
351 specificly for an SSL object with SSL_set_verify() is actually being
352 used. Before the change, a verify_callback set with this function was
353 ignored and the verify_callback() set in the SSL_CTX at the time of
354 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
355 to allow the necessary settings.
356 [Lutz Jaenicke]
357
358 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
359 explicitly to NULL, as at least on Solaris 8 this seems not always to be
360 done automatically (in contradiction to the requirements of the C
361 standard). This made problems when used from OpenSSH.
362 [Lutz Jaenicke]
363
364 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
365 dh->length and always used
366
367 BN_rand_range(priv_key, dh->p).
368
369 BN_rand_range() is not necessary for Diffie-Hellman, and this
370 specific range makes Diffie-Hellman unnecessarily inefficient if
371 dh->length (recommended exponent length) is much smaller than the
372 length of dh->p. We could use BN_rand_range() if the order of
373 the subgroup was stored in the DH structure, but we only have
374 dh->length.
375
376 So switch back to
377
378 BN_rand(priv_key, l, ...)
379
380 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
381 otherwise.
382 [Bodo Moeller]
383
384 *) In
385
386 RSA_eay_public_encrypt
387 RSA_eay_private_decrypt
388 RSA_eay_private_encrypt (signing)
389 RSA_eay_public_decrypt (signature verification)
390
391 (default implementations for RSA_public_encrypt,
392 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
393 always reject numbers >= n.
394 [Bodo Moeller]
395
396 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
397 to synchronize access to 'locking_thread'. This is necessary on
398 systems where access to 'locking_thread' (an 'unsigned long'
399 variable) is not atomic.
400 [Bodo Moeller]
401
402 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
403 *before* setting the 'crypto_lock_rand' flag. The previous code had
404 a race condition if 0 is a valid thread ID.
405 [Travis Vitek <vitek@roguewave.com>]
406
407 *) Add support for shared libraries under Irix.
408 [Albert Chin-A-Young <china@thewrittenword.com>]
409
410 *) Add configuration option to build on Linux on both big-endian and
411 little-endian MIPS.
412 [Ralf Baechle <ralf@uni-koblenz.de>]
413
414 *) Add the possibility to create shared libraries on HP-UX.
415 [Richard Levitte]
416
417 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
418
419 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
420 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
421 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
422 PRNG state recovery was possible based on the output of
423 one PRNG request appropriately sized to gain knowledge on
424 'md' followed by enough consecutive 1-byte PRNG requests
425 to traverse all of 'state'.
426
427 1. When updating 'md_local' (the current thread's copy of 'md')
428 during PRNG output generation, hash all of the previous
429 'md_local' value, not just the half used for PRNG output.
430
431 2. Make the number of bytes from 'state' included into the hash
432 independent from the number of PRNG bytes requested.
433
434 The first measure alone would be sufficient to avoid
435 Markku-Juhani's attack. (Actually it had never occurred
436 to me that the half of 'md_local' used for chaining was the
437 half from which PRNG output bytes were taken -- I had always
438 assumed that the secret half would be used.) The second
439 measure makes sure that additional data from 'state' is never
440 mixed into 'md_local' in small portions; this heuristically
441 further strengthens the PRNG.
442 [Bodo Moeller]
443
444 *) Fix crypto/bn/asm/mips3.s.
445 [Andy Polyakov]
446
447 *) When only the key is given to "enc", the IV is undefined. Print out
448 an error message in this case.
449 [Lutz Jaenicke]
450
451 *) Handle special case when X509_NAME is empty in X509 printing routines.
452 [Steve Henson]
453
454 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
455 positive and less than q.
456 [Bodo Moeller]
457
458 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
459 used: it isn't thread safe and the add_lock_callback should handle
460 that itself.
461 [Paul Rose <Paul.Rose@bridge.com>]
462
463 *) Verify that incoming data obeys the block size in
464 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
465 [Bodo Moeller]
466
467 *) Fix OAEP check.
468 [Ulf M�ller, Bodo M�ller]
469
470 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
471 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
472 when fixing the server behaviour for backwards-compatible 'client
473 hello' messages. (Note that the attack is impractical against
474 SSL 3.0 and TLS 1.0 anyway because length and version checking
475 means that the probability of guessing a valid ciphertext is
476 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
477 paper.)
478
479 Before 0.9.5, the countermeasure (hide the error by generating a
480 random 'decryption result') did not work properly because
481 ERR_clear_error() was missing, meaning that SSL_get_error() would
482 detect the supposedly ignored error.
483
484 Both problems are now fixed.
485 [Bodo Moeller]
486
487 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
488 (previously it was 1024).
489 [Bodo Moeller]
490
491 *) Fix for compatibility mode trust settings: ignore trust settings
492 unless some valid trust or reject settings are present.
493 [Steve Henson]
494
495 *) Fix for blowfish EVP: its a variable length cipher.
496 [Steve Henson]
497
498 *) Fix various bugs related to DSA S/MIME verification. Handle missing
499 parameters in DSA public key structures and return an error in the
500 DSA routines if parameters are absent.
501 [Steve Henson]
502
503 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
504 in the current directory if neither $RANDFILE nor $HOME was set.
505 RAND_file_name() in 0.9.6a returned NULL in this case. This has
506 caused some confusion to Windows users who haven't defined $HOME.
507 Thus RAND_file_name() is changed again: e_os.h can define a
508 DEFAULT_HOME, which will be used if $HOME is not set.
509 For Windows, we use "C:"; on other platforms, we still require
510 environment variables.
511
512 *) Move 'if (!initialized) RAND_poll()' into regions protected by
513 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
514 having multiple threads call RAND_poll() concurrently.
515 [Bodo Moeller]
516
517 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
518 combination of a flag and a thread ID variable.
519 Otherwise while one thread is in ssleay_rand_bytes (which sets the
520 flag), *other* threads can enter ssleay_add_bytes without obeying
521 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
522 that they do not hold after the first thread unsets add_do_not_lock).
523 [Bodo Moeller]
524
525 *) Change bctest again: '-x' expressions are not available in all
526 versions of 'test'.
527 [Bodo Moeller]
528
529 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
530
531 *) Fix a couple of memory leaks in PKCS7_dataDecode()
532 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
533
534 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
535 the default extension for executables, if any. Also, make the perl
536 scripts that use symlink() to test if it really exists and use "cp"
537 if it doesn't. All this made OpenSSL compilable and installable in
538 CygWin.
539 [Richard Levitte]
540
541 *) Fix for asn1_GetSequence() for indefinite length constructed data.
542 If SEQUENCE is length is indefinite just set c->slen to the total
543 amount of data available.
544 [Steve Henson, reported by shige@FreeBSD.org]
545 [This change does not apply to 0.9.7.]
546
547 *) Change bctest to avoid here-documents inside command substitution
548 (workaround for FreeBSD /bin/sh bug).
549 For compatibility with Ultrix, avoid shell functions (introduced
550 in the bctest version that searches along $PATH).
551 [Bodo Moeller]
552
553 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
554 with des_encrypt() defined on some operating systems, like Solaris
555 and UnixWare.
556 [Richard Levitte]
557
558 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
559 On the Importance of Eliminating Errors in Cryptographic
560 Computations, J. Cryptology 14 (2001) 2, 101-119,
561 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
562 [Ulf Moeller]
563
564 *) MIPS assembler BIGNUM division bug fix.
565 [Andy Polyakov]
566
567 *) Disabled incorrect Alpha assembler code.
568 [Richard Levitte]
569
570 *) Fix PKCS#7 decode routines so they correctly update the length
571 after reading an EOC for the EXPLICIT tag.
572 [Steve Henson]
573 [This change does not apply to 0.9.7.]
574
575 *) Fix bug in PKCS#12 key generation routines. This was triggered
576 if a 3DES key was generated with a 0 initial byte. Include
577 PKCS12_BROKEN_KEYGEN compilation option to retain the old
578 (but broken) behaviour.
579 [Steve Henson]
580
581 *) Enhance bctest to search for a working bc along $PATH and print
582 it when found.
583 [Tim Rice <tim@multitalents.net> via Richard Levitte]
584
585 *) Fix memory leaks in err.c: free err_data string if necessary;
586 don't write to the wrong index in ERR_set_error_data.
587 [Bodo Moeller]
588
589 *) Implement ssl23_peek (analogous to ssl23_read), which previously
590 did not exist.
591 [Bodo Moeller]
592
593 *) Replace rdtsc with _emit statements for VC++ version 5.
594 [Jeremy Cooper <jeremy@baymoo.org>]
595
596 *) Make it possible to reuse SSLv2 sessions.
597 [Richard Levitte]
598
599 *) In copy_email() check for >= 0 as a return value for
600 X509_NAME_get_index_by_NID() since 0 is a valid index.
601 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
602
603 *) Avoid coredump with unsupported or invalid public keys by checking if
604 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
605 PKCS7_verify() fails with non detached data.
606 [Steve Henson]
607
608 *) Don't use getenv in library functions when run as setuid/setgid.
609 New function OPENSSL_issetugid().
610 [Ulf Moeller]
611
612 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
613 due to incorrect handling of multi-threading:
614
615 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
616
617 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
618
619 3. Count how many times MemCheck_off() has been called so that
620 nested use can be treated correctly. This also avoids
621 inband-signalling in the previous code (which relied on the
622 assumption that thread ID 0 is impossible).
623 [Bodo Moeller]
624
625 *) Add "-rand" option also to s_client and s_server.
626 [Lutz Jaenicke]
627
628 *) Fix CPU detection on Irix 6.x.
629 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
630 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
631
632 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
633 was empty.
634 [Steve Henson]
635 [This change does not apply to 0.9.7.]
636
637 *) Use the cached encoding of an X509_NAME structure rather than
638 copying it. This is apparently the reason for the libsafe "errors"
639 but the code is actually correct.
640 [Steve Henson]
641
642 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
643 Bleichenbacher's DSA attack.
644 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
645 to be set and top=0 forces the highest bit to be set; top=-1 is new
646 and leaves the highest bit random.
647 [Ulf Moeller, Bodo Moeller]
648
649 *) In the NCONF_...-based implementations for CONF_... queries
650 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
651 a temporary CONF structure with the data component set to NULL
652 (which gives segmentation faults in lh_retrieve).
653 Instead, use NULL for the CONF pointer in CONF_get_string and
654 CONF_get_number (which may use environment variables) and directly
655 return NULL from CONF_get_section.
656 [Bodo Moeller]
657
658 *) Fix potential buffer overrun for EBCDIC.
659 [Ulf Moeller]
660
661 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
662 keyUsage if basicConstraints absent for a CA.
663 [Steve Henson]
664
665 *) Make SMIME_write_PKCS7() write mail header values with a format that
666 is more generally accepted (no spaces before the semicolon), since
667 some programs can't parse those values properly otherwise. Also make
668 sure BIO's that break lines after each write do not create invalid
669 headers.
670 [Richard Levitte]
671
672 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
673 macros previously used would not encode an empty SEQUENCE OF
674 and break the signature.
675 [Steve Henson]
676 [This change does not apply to 0.9.7.]
677
678 *) Zero the premaster secret after deriving the master secret in
679 DH ciphersuites.
680 [Steve Henson]
681
682 *) Add some EVP_add_digest_alias registrations (as found in
683 OpenSSL_add_all_digests()) to SSL_library_init()
684 aka OpenSSL_add_ssl_algorithms(). This provides improved
685 compatibility with peers using X.509 certificates
686 with unconventional AlgorithmIdentifier OIDs.
687 [Bodo Moeller]
688
689 *) Fix for Irix with NO_ASM.
690 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
691
692 *) ./config script fixes.
693 [Ulf Moeller, Richard Levitte]
694
695 *) Fix 'openssl passwd -1'.
696 [Bodo Moeller]
697
698 *) Change PKCS12_key_gen_asc() so it can cope with non null
699 terminated strings whose length is passed in the passlen
700 parameter, for example from PEM callbacks. This was done
701 by adding an extra length parameter to asc2uni().
702 [Steve Henson, reported by <oddissey@samsung.co.kr>]
703
704 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
705 call failed, free the DSA structure.
706 [Bodo Moeller]
707
708 *) Fix to uni2asc() to cope with zero length Unicode strings.
709 These are present in some PKCS#12 files.
710 [Steve Henson]
711
712 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
713 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
714 when writing a 32767 byte record.
715 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
716
717 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
718 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
719
720 (RSA objects have a reference count access to which is protected
721 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
722 so they are meant to be shared between threads.)
723 [Bodo Moeller, Geoff Thorpe; original patch submitted by
724 "Reddie, Steven" <Steven.Reddie@ca.com>]
725
726 *) Fix a deadlock in CRYPTO_mem_leaks().
727 [Bodo Moeller]
728
729 *) Use better test patterns in bntest.
730 [Ulf M�ller]
731
732 *) rand_win.c fix for Borland C.
733 [Ulf M�ller]
734
735 *) BN_rshift bugfix for n == 0.
736 [Bodo Moeller]
737
738 *) Add a 'bctest' script that checks for some known 'bc' bugs
739 so that 'make test' does not abort just because 'bc' is broken.
740 [Bodo Moeller]
741
742 *) Store verify_result within SSL_SESSION also for client side to
743 avoid potential security hole. (Re-used sessions on the client side
744 always resulted in verify_result==X509_V_OK, not using the original
745 result of the server certificate verification.)
746 [Lutz Jaenicke]
747
748 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
749 SSL3_RT_APPLICATION_DATA, return 0.
750 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
751 [Bodo Moeller]
752
753 *) Fix SSL_peek:
754 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
755 releases, have been re-implemented by renaming the previous
756 implementations of ssl2_read and ssl3_read to ssl2_read_internal
757 and ssl3_read_internal, respectively, and adding 'peek' parameters
758 to them. The new ssl[23]_{read,peek} functions are calls to
759 ssl[23]_read_internal with the 'peek' flag set appropriately.
760 A 'peek' parameter has also been added to ssl3_read_bytes, which
761 does the actual work for ssl3_read_internal.
762 [Bodo Moeller]
763
764 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
765 the method-specific "init()" handler. Also clean up ex_data after
766 calling the method-specific "finish()" handler. Previously, this was
767 happening the other way round.
768 [Geoff Thorpe]
769
770 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
771 The previous value, 12, was not always sufficient for BN_mod_exp().
772 [Bodo Moeller]
773
774 *) Make sure that shared libraries get the internal name engine with
775 the full version number and not just 0. This should mark the
776 shared libraries as not backward compatible. Of course, this should
777 be changed again when we can guarantee backward binary compatibility.
778 [Richard Levitte]
779
780 *) Fix typo in get_cert_by_subject() in by_dir.c
781 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
782
783 *) Rework the system to generate shared libraries:
784
785 - Make note of the expected extension for the shared libraries and
786 if there is a need for symbolic links from for example libcrypto.so.0
787 to libcrypto.so.0.9.7. There is extended info in Configure for
788 that.
789
790 - Make as few rebuilds of the shared libraries as possible.
791
792 - Still avoid linking the OpenSSL programs with the shared libraries.
793
794 - When installing, install the shared libraries separately from the
795 static ones.
796 [Richard Levitte]
797
798 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
799
800 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
801 and not in SSL_clear because the latter is also used by the
802 accept/connect functions; previously, the settings made by
803 SSL_set_read_ahead would be lost during the handshake.
804 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
805
806 *) Correct util/mkdef.pl to be selective about disabled algorithms.
807 Previously, it would create entries for disableed algorithms no
808 matter what.
809 [Richard Levitte]
810
811 *) Added several new manual pages for SSL_* function.
812 [Lutz Jaenicke]
813
814 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
815
816 *) In ssl23_get_client_hello, generate an error message when faced
817 with an initial SSL 3.0/TLS record that is too small to contain the
818 first two bytes of the ClientHello message, i.e. client_version.
819 (Note that this is a pathologic case that probably has never happened
820 in real life.) The previous approach was to use the version number
821 from the record header as a substitute; but our protocol choice
822 should not depend on that one because it is not authenticated
823 by the Finished messages.
824 [Bodo Moeller]
825
826 *) More robust randomness gathering functions for Windows.
827 [Jeffrey Altman <jaltman@columbia.edu>]
828
829 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
830 not set then we don't setup the error code for issuer check errors
831 to avoid possibly overwriting other errors which the callback does
832 handle. If an application does set the flag then we assume it knows
833 what it is doing and can handle the new informational codes
834 appropriately.
835 [Steve Henson]
836
837 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
838 a general "ANY" type, as such it should be able to decode anything
839 including tagged types. However it didn't check the class so it would
840 wrongly interpret tagged types in the same way as their universal
841 counterpart and unknown types were just rejected. Changed so that the
842 tagged and unknown types are handled in the same way as a SEQUENCE:
843 that is the encoding is stored intact. There is also a new type
844 "V_ASN1_OTHER" which is used when the class is not universal, in this
845 case we have no idea what the actual type is so we just lump them all
846 together.
847 [Steve Henson]
848
849 *) On VMS, stdout may very well lead to a file that is written to
850 in a record-oriented fashion. That means that every write() will
851 write a separate record, which will be read separately by the
852 programs trying to read from it. This can be very confusing.
853
854 The solution is to put a BIO filter in the way that will buffer
855 text until a linefeed is reached, and then write everything a
856 line at a time, so every record written will be an actual line,
857 not chunks of lines and not (usually doesn't happen, but I've
858 seen it once) several lines in one record. BIO_f_linebuffer() is
859 the answer.
860
861 Currently, it's a VMS-only method, because that's where it has
862 been tested well enough.
863 [Richard Levitte]
864
865 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
866 it can return incorrect results.
867 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
868 but it was in 0.9.6-beta[12].)
869 [Bodo Moeller]
870
871 *) Disable the check for content being present when verifying detached
872 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
873 include zero length content when signing messages.
874 [Steve Henson]
875
876 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
877 BIO_ctrl (for BIO pairs).
878 [Bodo M�ller]
879
880 *) Add DSO method for VMS.
881 [Richard Levitte]
882
883 *) Bug fix: Montgomery multiplication could produce results with the
884 wrong sign.
885 [Ulf M�ller]
886
887 *) Add RPM specification openssl.spec and modify it to build three
888 packages. The default package contains applications, application
889 documentation and run-time libraries. The devel package contains
890 include files, static libraries and function documentation. The
891 doc package contains the contents of the doc directory. The original
892 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
893 [Richard Levitte]
894
895 *) Add a large number of documentation files for many SSL routines.
896 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
897
898 *) Add a configuration entry for Sony News 4.
899 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
900
901 *) Don't set the two most significant bits to one when generating a
902 random number < q in the DSA library.
903 [Ulf M�ller]
904
905 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
906 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
907 the underlying transport is blocking) if a handshake took place.
908 (The default behaviour is needed by applications such as s_client
909 and s_server that use select() to determine when to use SSL_read;
910 but for applications that know in advance when to expect data, it
911 just makes things more complicated.)
912 [Bodo Moeller]
913
914 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
915 from EGD.
916 [Ben Laurie]
917
918 *) Add a few more EBCDIC conditionals that make `req' and `x509'
919 work better on such systems.
920 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
921
922 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
923 Update PKCS12_parse() so it copies the friendlyName and the
924 keyid to the certificates aux info.
925 [Steve Henson]
926
927 *) Fix bug in PKCS7_verify() which caused an infinite loop
928 if there was more than one signature.
929 [Sven Uszpelkat <su@celocom.de>]
930
931 *) Major change in util/mkdef.pl to include extra information
932 about each symbol, as well as presentig variables as well
933 as functions. This change means that there's n more need
934 to rebuild the .num files when some algorithms are excluded.
935 [Richard Levitte]
936
937 *) Allow the verify time to be set by an application,
938 rather than always using the current time.
939 [Steve Henson]
940
941 *) Phase 2 verify code reorganisation. The certificate
942 verify code now looks up an issuer certificate by a
943 number of criteria: subject name, authority key id
944 and key usage. It also verifies self signed certificates
945 by the same criteria. The main comparison function is
946 X509_check_issued() which performs these checks.
947
948 Lot of changes were necessary in order to support this
949 without completely rewriting the lookup code.
950
951 Authority and subject key identifier are now cached.
952
953 The LHASH 'certs' is X509_STORE has now been replaced
954 by a STACK_OF(X509_OBJECT). This is mainly because an
955 LHASH can't store or retrieve multiple objects with
956 the same hash value.
957
958 As a result various functions (which were all internal
959 use only) have changed to handle the new X509_STORE
960 structure. This will break anything that messed round
961 with X509_STORE internally.
962
963 The functions X509_STORE_add_cert() now checks for an
964 exact match, rather than just subject name.
965
966 The X509_STORE API doesn't directly support the retrieval
967 of multiple certificates matching a given criteria, however
968 this can be worked round by performing a lookup first
969 (which will fill the cache with candidate certificates)
970 and then examining the cache for matches. This is probably
971 the best we can do without throwing out X509_LOOKUP
972 entirely (maybe later...).
973
974 The X509_VERIFY_CTX structure has been enhanced considerably.
975
976 All certificate lookup operations now go via a get_issuer()
977 callback. Although this currently uses an X509_STORE it
978 can be replaced by custom lookups. This is a simple way
979 to bypass the X509_STORE hackery necessary to make this
980 work and makes it possible to use more efficient techniques
981 in future. A very simple version which uses a simple
982 STACK for its trusted certificate store is also provided
983 using X509_STORE_CTX_trusted_stack().
984
985 The verify_cb() and verify() callbacks now have equivalents
986 in the X509_STORE_CTX structure.
987
988 X509_STORE_CTX also has a 'flags' field which can be used
989 to customise the verify behaviour.
990 [Steve Henson]
991
992 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
993 excludes S/MIME capabilities.
994 [Steve Henson]
995
996 *) When a certificate request is read in keep a copy of the
997 original encoding of the signed data and use it when outputing
998 again. Signatures then use the original encoding rather than
999 a decoded, encoded version which may cause problems if the
1000 request is improperly encoded.
1001 [Steve Henson]
1002
1003 *) For consistency with other BIO_puts implementations, call
1004 buffer_write(b, ...) directly in buffer_puts instead of calling
1005 BIO_write(b, ...).
1006
1007 In BIO_puts, increment b->num_write as in BIO_write.
1008 [Peter.Sylvester@EdelWeb.fr]
1009
1010 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1011 BN_zero, we may not return a BIGNUM with an array consisting of
1012 words set to zero.)
1013 [Bodo Moeller]
1014
1015 *) Avoid calling abort() from within the library when problems are
1016 detected, except if preprocessor symbols have been defined
1017 (such as REF_CHECK, BN_DEBUG etc.).
1018 [Bodo Moeller]
1019
1020 *) New openssl application 'rsautl'. This utility can be
1021 used for low level RSA operations. DER public key
1022 BIO/fp routines also added.
1023 [Steve Henson]
1024
1025 *) New Configure entry and patches for compiling on QNX 4.
1026 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1027
1028 *) A demo state-machine implementation was sponsored by
1029 Nuron (http://www.nuron.com/) and is now available in
1030 demos/state_machine.
1031 [Ben Laurie]
1032
1033 *) New options added to the 'dgst' utility for signature
1034 generation and verification.
1035 [Steve Henson]
1036
1037 *) Unrecognized PKCS#7 content types are now handled via a
1038 catch all ASN1_TYPE structure. This allows unsupported
1039 types to be stored as a "blob" and an application can
1040 encode and decode it manually.
1041 [Steve Henson]
1042
1043 *) Fix various signed/unsigned issues to make a_strex.c
1044 compile under VC++.
1045 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
1046
1047 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
1048 length if passed a buffer. ASN1_INTEGER_to_BN failed
1049 if passed a NULL BN and its argument was negative.
1050 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
1051
1052 *) Modification to PKCS#7 encoding routines to output definite
1053 length encoding. Since currently the whole structures are in
1054 memory there's not real point in using indefinite length
1055 constructed encoding. However if OpenSSL is compiled with
1056 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
1057 [Steve Henson]
1058
1059 *) Added BIO_vprintf() and BIO_vsnprintf().
1060 [Richard Levitte]
1061
1062 *) Added more prefixes to parse for in the the strings written
1063 through a logging bio, to cover all the levels that are available
1064 through syslog. The prefixes are now:
1065
1066 PANIC, EMERG, EMR => LOG_EMERG
1067 ALERT, ALR => LOG_ALERT
1068 CRIT, CRI => LOG_CRIT
1069 ERROR, ERR => LOG_ERR
1070 WARNING, WARN, WAR => LOG_WARNING
1071 NOTICE, NOTE, NOT => LOG_NOTICE
1072 INFO, INF => LOG_INFO
1073 DEBUG, DBG => LOG_DEBUG
1074
1075 and as before, if none of those prefixes are present at the
1076 beginning of the string, LOG_ERR is chosen.
1077
1078 On Win32, the LOG_* levels are mapped according to this:
1079
1080 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
1081 LOG_WARNING => EVENTLOG_WARNING_TYPE
1082 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
1083
1084 [Richard Levitte]
1085
1086 *) Made it possible to reconfigure with just the configuration
1087 argument "reconf" or "reconfigure". The command line arguments
1088 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
1089 and are retrieved from there when reconfiguring.
1090 [Richard Levitte]
1091
1092 *) MD4 implemented.
1093 [Assar Westerlund <assar@sics.se>, Richard Levitte]
1094
1095 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
1096 [Richard Levitte]
1097
1098 *) The obj_dat.pl script was messing up the sorting of object
1099 names. The reason was that it compared the quoted version
1100 of strings as a result "OCSP" > "OCSP Signing" because
1101 " > SPACE. Changed script to store unquoted versions of
1102 names and add quotes on output. It was also omitting some
1103 names from the lookup table if they were given a default
1104 value (that is if SN is missing it is given the same
1105 value as LN and vice versa), these are now added on the
1106 grounds that if an object has a name we should be able to
1107 look it up. Finally added warning output when duplicate
1108 short or long names are found.
1109 [Steve Henson]
1110
1111 *) Changes needed for Tandem NSK.
1112 [Scott Uroff <scott@xypro.com>]
1113
1114 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
1115 RSA_padding_check_SSLv23(), special padding was never detected
1116 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
1117 version rollback attacks was not effective.
1118
1119 In s23_clnt.c, don't use special rollback-attack detection padding
1120 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
1121 client; similarly, in s23_srvr.c, don't do the rollback check if
1122 SSL 2.0 is the only protocol enabled in the server.
1123 [Bodo Moeller]
1124
1125 *) Make it possible to get hexdumps of unprintable data with 'openssl
1126 asn1parse'. By implication, the functions ASN1_parse_dump() and
1127 BIO_dump_indent() are added.
1128 [Richard Levitte]
1129
1130 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
1131 these print out strings and name structures based on various
1132 flags including RFC2253 support and proper handling of
1133 multibyte characters. Added options to the 'x509' utility
1134 to allow the various flags to be set.
1135 [Steve Henson]
1136
1137 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
1138 Also change the functions X509_cmp_current_time() and
1139 X509_gmtime_adj() work with an ASN1_TIME structure,
1140 this will enable certificates using GeneralizedTime in validity
1141 dates to be checked.
1142 [Steve Henson]
1143
1144 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
1145 negative public key encodings) on by default,
1146 NO_NEG_PUBKEY_BUG can be set to disable it.
1147 [Steve Henson]
1148
1149 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
1150 content octets. An i2c_ASN1_OBJECT is unnecessary because
1151 the encoding can be trivially obtained from the structure.
1152 [Steve Henson]
1153
1154 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
1155 not read locks (CRYPTO_r_[un]lock).
1156 [Bodo Moeller]
1157
1158 *) A first attempt at creating official support for shared
1159 libraries through configuration. I've kept it so the
1160 default is static libraries only, and the OpenSSL programs
1161 are always statically linked for now, but there are
1162 preparations for dynamic linking in place.
1163 This has been tested on Linux and Tru64.
1164 [Richard Levitte]
1165
1166 *) Randomness polling function for Win9x, as described in:
1167 Peter Gutmann, Software Generation of Practically Strong
1168 Random Numbers.
1169 [Ulf M�ller]
1170
1171 *) Fix so PRNG is seeded in req if using an already existing
1172 DSA key.
1173 [Steve Henson]
1174
1175 *) New options to smime application. -inform and -outform
1176 allow alternative formats for the S/MIME message including
1177 PEM and DER. The -content option allows the content to be
1178 specified separately. This should allow things like Netscape
1179 form signing output easier to verify.
1180 [Steve Henson]
1181
1182 *) Fix the ASN1 encoding of tags using the 'long form'.
1183 [Steve Henson]
1184
1185 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
1186 STRING types. These convert content octets to and from the
1187 underlying type. The actual tag and length octets are
1188 already assumed to have been read in and checked. These
1189 are needed because all other string types have virtually
1190 identical handling apart from the tag. By having versions
1191 of the ASN1 functions that just operate on content octets
1192 IMPLICIT tagging can be handled properly. It also allows
1193 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
1194 and ASN1_INTEGER are identical apart from the tag.
1195 [Steve Henson]
1196
1197 *) Change the handling of OID objects as follows:
1198
1199 - New object identifiers are inserted in objects.txt, following
1200 the syntax given in objects.README.
1201 - objects.pl is used to process obj_mac.num and create a new
1202 obj_mac.h.
1203 - obj_dat.pl is used to create a new obj_dat.h, using the data in
1204 obj_mac.h.
1205
1206 This is currently kind of a hack, and the perl code in objects.pl
1207 isn't very elegant, but it works as I intended. The simplest way
1208 to check that it worked correctly is to look in obj_dat.h and
1209 check the array nid_objs and make sure the objects haven't moved
1210 around (this is important!). Additions are OK, as well as
1211 consistent name changes.
1212 [Richard Levitte]
1213
1214 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
1215 [Bodo Moeller]
1216
1217 *) Addition of the command line parameter '-rand file' to 'openssl req'.
1218 The given file adds to whatever has already been seeded into the
1219 random pool through the RANDFILE configuration file option or
1220 environment variable, or the default random state file.
1221 [Richard Levitte]
1222
1223 *) mkstack.pl now sorts each macro group into lexical order.
1224 Previously the output order depended on the order the files
1225 appeared in the directory, resulting in needless rewriting
1226 of safestack.h .
1227 [Steve Henson]
1228
1229 *) Patches to make OpenSSL compile under Win32 again. Mostly
1230 work arounds for the VC++ problem that it treats func() as
1231 func(void). Also stripped out the parts of mkdef.pl that
1232 added extra typesafe functions: these no longer exist.
1233 [Steve Henson]
1234
1235 *) Reorganisation of the stack code. The macros are now all
1236 collected in safestack.h . Each macro is defined in terms of
1237 a "stack macro" of the form SKM_<name>(type, a, b). The
1238 DEBUG_SAFESTACK is now handled in terms of function casts,
1239 this has the advantage of retaining type safety without the
1240 use of additional functions. If DEBUG_SAFESTACK is not defined
1241 then the non typesafe macros are used instead. Also modified the
1242 mkstack.pl script to handle the new form. Needs testing to see
1243 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
1244 the default if no major problems. Similar behaviour for ASN1_SET_OF
1245 and PKCS12_STACK_OF.
1246 [Steve Henson]
1247
1248 *) When some versions of IIS use the 'NET' form of private key the
1249 key derivation algorithm is different. Normally MD5(password) is
1250 used as a 128 bit RC4 key. In the modified case
1251 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
1252 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
1253 as the old Netscape_RSA functions except they have an additional
1254 'sgckey' parameter which uses the modified algorithm. Also added
1255 an -sgckey command line option to the rsa utility. Thanks to
1256 Adrian Peck <bertie@ncipher.com> for posting details of the modified
1257 algorithm to openssl-dev.
1258 [Steve Henson]
1259
1260 *) The evp_local.h macros were using 'c.##kname' which resulted in
1261 invalid expansion on some systems (SCO 5.0.5 for example).
1262 Corrected to 'c.kname'.
1263 [Phillip Porch <root@theporch.com>]
1264
1265 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
1266 a STACK of email addresses from a certificate or request, these look
1267 in the subject name and the subject alternative name extensions and
1268 omit any duplicate addresses.
1269 [Steve Henson]
1270
1271 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
1272 This makes DSA verification about 2 % faster.
1273 [Bodo Moeller]
1274
1275 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
1276 (meaning that now 2^5 values will be precomputed, which is only 4 KB
1277 plus overhead for 1024 bit moduli).
1278 This makes exponentiations about 0.5 % faster for 1024 bit
1279 exponents (as measured by "openssl speed rsa2048").
1280 [Bodo Moeller]
1281
1282 *) Rename memory handling macros to avoid conflicts with other
1283 software:
1284 Malloc => OPENSSL_malloc
1285 Malloc_locked => OPENSSL_malloc_locked
1286 Realloc => OPENSSL_realloc
1287 Free => OPENSSL_free
1288 [Richard Levitte]
1289
1290 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
1291 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
1292 [Bodo Moeller]
1293
1294 *) CygWin32 support.
1295 [John Jarvie <jjarvie@newsguy.com>]
1296
1297 *) The type-safe stack code has been rejigged. It is now only compiled
1298 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
1299 by default all type-specific stack functions are "#define"d back to
1300 standard stack functions. This results in more streamlined output
1301 but retains the type-safety checking possibilities of the original
1302 approach.
1303 [Geoff Thorpe]
1304
1305 *) The STACK code has been cleaned up, and certain type declarations
1306 that didn't make a lot of sense have been brought in line. This has
1307 also involved a cleanup of sorts in safestack.h to more correctly
1308 map type-safe stack functions onto their plain stack counterparts.
1309 This work has also resulted in a variety of "const"ifications of
1310 lots of the code, especially "_cmp" operations which should normally
1311 be prototyped with "const" parameters anyway.
1312 [Geoff Thorpe]
1313
1314 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
1315 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
1316 (The PRNG state consists of two parts, the large pool 'state' and 'md',
1317 where all of 'md' is used each time the PRNG is used, but 'state'
1318 is used only indexed by a cyclic counter. As entropy may not be
1319 well distributed from the beginning, 'md' is important as a
1320 chaining variable. However, the output function chains only half
1321 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
1322 all of 'md', and seeding with STATE_SIZE dummy bytes will result
1323 in all of 'state' being rewritten, with the new values depending
1324 on virtually all of 'md'. This overcomes the 80 bit limitation.)
1325 [Bodo Moeller]
1326
1327 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
1328 the handshake is continued after ssl_verify_cert_chain();
1329 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
1330 can lead to 'unexplainable' connection aborts later.
1331 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
1332
1333 *) Major EVP API cipher revision.
1334 Add hooks for extra EVP features. This allows various cipher
1335 parameters to be set in the EVP interface. Support added for variable
1336 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
1337 setting of RC2 and RC5 parameters.
1338
1339 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
1340 ciphers.
1341
1342 Remove lots of duplicated code from the EVP library. For example *every*
1343 cipher init() function handles the 'iv' in the same way according to the
1344 cipher mode. They also all do nothing if the 'key' parameter is NULL and
1345 for CFB and OFB modes they zero ctx->num.
1346
1347 New functionality allows removal of S/MIME code RC2 hack.
1348
1349 Most of the routines have the same form and so can be declared in terms
1350 of macros.
1351
1352 By shifting this to the top level EVP_CipherInit() it can be removed from
1353 all individual ciphers. If the cipher wants to handle IVs or keys
1354 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
1355 flags.
1356
1357 Change lots of functions like EVP_EncryptUpdate() to now return a
1358 value: although software versions of the algorithms cannot fail
1359 any installed hardware versions can.
1360 [Steve Henson]
1361
1362 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
1363 this option is set, tolerate broken clients that send the negotiated
1364 protocol version number instead of the requested protocol version
1365 number.
1366 [Bodo Moeller]
1367
1368 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
1369 i.e. non-zero for export ciphersuites, zero otherwise.
1370 Previous versions had this flag inverted, inconsistent with
1371 rsa_tmp_cb (..._TMP_RSA_CB).
1372 [Bodo Moeller; problem reported by Amit Chopra]
1373
1374 *) Add missing DSA library text string. Work around for some IIS
1375 key files with invalid SEQUENCE encoding.
1376 [Steve Henson]
1377
1378 *) Add a document (doc/standards.txt) that list all kinds of standards
1379 and so on that are implemented in OpenSSL.
1380 [Richard Levitte]
1381
1382 *) Enhance c_rehash script. Old version would mishandle certificates
1383 with the same subject name hash and wouldn't handle CRLs at all.
1384 Added -fingerprint option to crl utility, to support new c_rehash
1385 features.
1386 [Steve Henson]
1387
1388 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
1389 [Ulf M�ller]
1390
1391 *) Fix for SSL server purpose checking. Server checking was
1392 rejecting certificates which had extended key usage present
1393 but no ssl client purpose.
1394 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
1395
1396 *) Make PKCS#12 code work with no password. The PKCS#12 spec
1397 is a little unclear about how a blank password is handled.
1398 Since the password in encoded as a BMPString with terminating
1399 double NULL a zero length password would end up as just the
1400 double NULL. However no password at all is different and is
1401 handled differently in the PKCS#12 key generation code. NS
1402 treats a blank password as zero length. MSIE treats it as no
1403 password on export: but it will try both on import. We now do
1404 the same: PKCS12_parse() tries zero length and no password if
1405 the password is set to "" or NULL (NULL is now a valid password:
1406 it wasn't before) as does the pkcs12 application.
1407 [Steve Henson]
1408
1409 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
1410 perror when PEM_read_bio_X509_REQ fails, the error message must
1411 be obtained from the error queue.
1412 [Bodo Moeller]
1413
1414 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
1415 it in ERR_remove_state if appropriate, and change ERR_get_state
1416 accordingly to avoid race conditions (this is necessary because
1417 thread_hash is no longer constant once set).
1418 [Bodo Moeller]
1419
1420 *) Bugfix for linux-elf makefile.one.
1421 [Ulf M�ller]
1422
1423 *) RSA_get_default_method() will now cause a default
1424 RSA_METHOD to be chosen if one doesn't exist already.
1425 Previously this was only set during a call to RSA_new()
1426 or RSA_new_method(NULL) meaning it was possible for
1427 RSA_get_default_method() to return NULL.
1428 [Geoff Thorpe]
1429
1430 *) Added native name translation to the existing DSO code
1431 that will convert (if the flag to do so is set) filenames
1432 that are sufficiently small and have no path information
1433 into a canonical native form. Eg. "blah" converted to
1434 "libblah.so" or "blah.dll" etc.
1435 [Geoff Thorpe]
1436
1437 *) New function ERR_error_string_n(e, buf, len) which is like
1438 ERR_error_string(e, buf), but writes at most 'len' bytes
1439 including the 0 terminator. For ERR_error_string_n, 'buf'
1440 may not be NULL.
1441 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
1442
1443 *) CONF library reworked to become more general. A new CONF
1444 configuration file reader "class" is implemented as well as a
1445 new functions (NCONF_*, for "New CONF") to handle it. The now
1446 old CONF_* functions are still there, but are reimplemented to
1447 work in terms of the new functions. Also, a set of functions
1448 to handle the internal storage of the configuration data is
1449 provided to make it easier to write new configuration file
1450 reader "classes" (I can definitely see something reading a
1451 configuration file in XML format, for example), called _CONF_*,
1452 or "the configuration storage API"...
1453
1454 The new configuration file reading functions are:
1455
1456 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
1457 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
1458
1459 NCONF_default, NCONF_WIN32
1460
1461 NCONF_dump_fp, NCONF_dump_bio
1462
1463 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
1464 NCONF_new creates a new CONF object. This works in the same way
1465 as other interfaces in OpenSSL, like the BIO interface.
1466 NCONF_dump_* dump the internal storage of the configuration file,
1467 which is useful for debugging. All other functions take the same
1468 arguments as the old CONF_* functions wth the exception of the
1469 first that must be a `CONF *' instead of a `LHASH *'.
1470
1471 To make it easer to use the new classes with the old CONF_* functions,
1472 the function CONF_set_default_method is provided.
1473 [Richard Levitte]
1474
1475 *) Add '-tls1' option to 'openssl ciphers', which was already
1476 mentioned in the documentation but had not been implemented.
1477 (This option is not yet really useful because even the additional
1478 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
1479 [Bodo Moeller]
1480
1481 *) Initial DSO code added into libcrypto for letting OpenSSL (and
1482 OpenSSL-based applications) load shared libraries and bind to
1483 them in a portable way.
1484 [Geoff Thorpe, with contributions from Richard Levitte]
1485
1486 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
1487
1488 *) Make sure _lrotl and _lrotr are only used with MSVC.
1489
1490 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
1491 (the default implementation of RAND_status).
1492
1493 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
1494 to '-clrext' (= clear extensions), as intended and documented.
1495 [Bodo Moeller; inconsistency pointed out by Michael Attili
1496 <attili@amaxo.com>]
1497
1498 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
1499 was larger than the MD block size.
1500 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
1501
1502 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
1503 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
1504 using the passed key: if the passed key was a private key the result
1505 of X509_print(), for example, would be to print out all the private key
1506 components.
1507 [Steve Henson]
1508
1509 *) des_quad_cksum() byte order bug fix.
1510 [Ulf M�ller, using the problem description in krb4-0.9.7, where
1511 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
1512
1513 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
1514 discouraged.
1515 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
1516
1517 *) For easily testing in shell scripts whether some command
1518 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
1519 returns with exit code 0 iff no command of the given name is available.
1520 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
1521 the output goes to stdout and nothing is printed to stderr.
1522 Additional arguments are always ignored.
1523
1524 Since for each cipher there is a command of the same name,
1525 the 'no-cipher' compilation switches can be tested this way.
1526
1527 ('openssl no-XXX' is not able to detect pseudo-commands such
1528 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
1529 [Bodo Moeller]
1530
1531 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
1532 [Bodo Moeller]
1533
1534 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
1535 is set; it will be thrown away anyway because each handshake creates
1536 its own key.
1537 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
1538 to parameters -- in previous versions (since OpenSSL 0.9.3) the
1539 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
1540 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
1541 [Bodo Moeller]
1542
1543 *) New s_client option -ign_eof: EOF at stdin is ignored, and
1544 'Q' and 'R' lose their special meanings (quit/renegotiate).
1545 This is part of what -quiet does; unlike -quiet, -ign_eof
1546 does not suppress any output.
1547 [Richard Levitte]
1548
1549 *) Add compatibility options to the purpose and trust code. The
1550 purpose X509_PURPOSE_ANY is "any purpose" which automatically
1551 accepts a certificate or CA, this was the previous behaviour,
1552 with all the associated security issues.
1553
1554 X509_TRUST_COMPAT is the old trust behaviour: only and
1555 automatically trust self signed roots in certificate store. A
1556 new trust setting X509_TRUST_DEFAULT is used to specify that
1557 a purpose has no associated trust setting and it should instead
1558 use the value in the default purpose.
1559 [Steve Henson]
1560
1561 *) Fix the PKCS#8 DSA private key code so it decodes keys again
1562 and fix a memory leak.
1563 [Steve Henson]
1564
1565 *) In util/mkerr.pl (which implements 'make errors'), preserve
1566 reason strings from the previous version of the .c file, as
1567 the default to have only downcase letters (and digits) in
1568 automatically generated reasons codes is not always appropriate.
1569 [Bodo Moeller]
1570
1571 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
1572 using strerror. Previously, ERR_reason_error_string() returned
1573 library names as reason strings for SYSerr; but SYSerr is a special
1574 case where small numbers are errno values, not library numbers.
1575 [Bodo Moeller]
1576
1577 *) Add '-dsaparam' option to 'openssl dhparam' application. This
1578 converts DSA parameters into DH parameters. (When creating parameters,
1579 DSA_generate_parameters is used.)
1580 [Bodo Moeller]
1581
1582 *) Include 'length' (recommended exponent length) in C code generated
1583 by 'openssl dhparam -C'.
1584 [Bodo Moeller]
1585
1586 *) The second argument to set_label in perlasm was already being used
1587 so couldn't be used as a "file scope" flag. Moved to third argument
1588 which was free.
1589 [Steve Henson]
1590
1591 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1592 instead of RAND_bytes for encryption IVs and salts.
1593 [Bodo Moeller]
1594
1595 *) Include RAND_status() into RAND_METHOD instead of implementing
1596 it only for md_rand.c Otherwise replacing the PRNG by calling
1597 RAND_set_rand_method would be impossible.
1598 [Bodo Moeller]
1599
1600 *) Don't let DSA_generate_key() enter an infinite loop if the random
1601 number generation fails.
1602 [Bodo Moeller]
1603
1604 *) New 'rand' application for creating pseudo-random output.
1605 [Bodo Moeller]
1606
1607 *) Added configuration support for Linux/IA64
1608 [Rolf Haberrecker <rolf@suse.de>]
1609
1610 *) Assembler module support for Mingw32.
1611 [Ulf M�ller]
1612
1613 *) Shared library support for HPUX (in shlib/).
1614 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1615
1616 *) Shared library support for Solaris gcc.
1617 [Lutz Behnke <behnke@trustcenter.de>]
1618
1619 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1620
1621 *) PKCS7_encrypt() was adding text MIME headers twice because they
1622 were added manually and by SMIME_crlf_copy().
1623 [Steve Henson]
1624
1625 *) In bntest.c don't call BN_rand with zero bits argument.
1626 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
1627
1628 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
1629 case was implemented. This caused BN_div_recp() to fail occasionally.
1630 [Ulf M�ller]
1631
1632 *) Add an optional second argument to the set_label() in the perl
1633 assembly language builder. If this argument exists and is set
1634 to 1 it signals that the assembler should use a symbol whose
1635 scope is the entire file, not just the current function. This
1636 is needed with MASM which uses the format label:: for this scope.
1637 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
1638
1639 *) Change the ASN1 types so they are typedefs by default. Before
1640 almost all types were #define'd to ASN1_STRING which was causing
1641 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
1642 for example.
1643 [Steve Henson]
1644
1645 *) Change names of new functions to the new get1/get0 naming
1646 convention: After 'get1', the caller owns a reference count
1647 and has to call ..._free; 'get0' returns a pointer to some
1648 data structure without incrementing reference counters.
1649 (Some of the existing 'get' functions increment a reference
1650 counter, some don't.)
1651 Similarly, 'set1' and 'add1' functions increase reference
1652 counters or duplicate objects.
1653 [Steve Henson]
1654
1655 *) Allow for the possibility of temp RSA key generation failure:
1656 the code used to assume it always worked and crashed on failure.
1657 [Steve Henson]
1658
1659 *) Fix potential buffer overrun problem in BIO_printf().
1660 [Ulf M�ller, using public domain code by Patrick Powell; problem
1661 pointed out by David Sacerdote <das33@cornell.edu>]
1662
1663 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
1664 RAND_egd() and RAND_status(). In the command line application,
1665 the EGD socket can be specified like a seed file using RANDFILE
1666 or -rand.
1667 [Ulf M�ller]
1668
1669 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
1670 Some CAs (e.g. Verisign) distribute certificates in this form.
1671 [Steve Henson]
1672
1673 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
1674 list to exclude them. This means that no special compilation option
1675 is needed to use anonymous DH: it just needs to be included in the
1676 cipher list.
1677 [Steve Henson]
1678
1679 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
1680 EVP_MD_type. The old functionality is available in a new macro called
1681 EVP_MD_md(). Change code that uses it and update docs.
1682 [Steve Henson]
1683
1684 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
1685 where the 'void *' argument is replaced by a function pointer argument.
1686 Previously 'void *' was abused to point to functions, which works on
1687 many platforms, but is not correct. As these functions are usually
1688 called by macros defined in OpenSSL header files, most source code
1689 should work without changes.
1690 [Richard Levitte]
1691
1692 *) <openssl/opensslconf.h> (which is created by Configure) now contains
1693 sections with information on -D... compiler switches used for
1694 compiling the library so that applications can see them. To enable
1695 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
1696 must be defined. E.g.,
1697 #define OPENSSL_ALGORITHM_DEFINES
1698 #include <openssl/opensslconf.h>
1699 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
1700 [Richard Levitte, Ulf and Bodo M�ller]
1701
1702 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
1703 record layer.
1704 [Bodo Moeller]
1705
1706 *) Change the 'other' type in certificate aux info to a STACK_OF
1707 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
1708 the required ASN1 format: arbitrary types determined by an OID.
1709 [Steve Henson]
1710
1711 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1712 argument to 'req'. This is not because the function is newer or
1713 better than others it just uses the work 'NEW' in the certificate
1714 request header lines. Some software needs this.
1715 [Steve Henson]
1716
1717 *) Reorganise password command line arguments: now passwords can be
1718 obtained from various sources. Delete the PEM_cb function and make
1719 it the default behaviour: i.e. if the callback is NULL and the
1720 usrdata argument is not NULL interpret it as a null terminated pass
1721 phrase. If usrdata and the callback are NULL then the pass phrase
1722 is prompted for as usual.
1723 [Steve Henson]
1724
1725 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
1726 the support is automatically enabled. The resulting binaries will
1727 autodetect the card and use it if present.
1728 [Ben Laurie and Compaq Inc.]
1729
1730 *) Work around for Netscape hang bug. This sends certificate request
1731 and server done in one record. Since this is perfectly legal in the
1732 SSL/TLS protocol it isn't a "bug" option and is on by default. See
1733 the bugs/SSLv3 entry for more info.
1734 [Steve Henson]
1735
1736 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
1737 [Andy Polyakov]
1738
1739 *) Add -rand argument to smime and pkcs12 applications and read/write
1740 of seed file.
1741 [Steve Henson]
1742
1743 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
1744 [Bodo Moeller]
1745
1746 *) Add command line password options to the remaining applications.
1747 [Steve Henson]
1748
1749 *) Bug fix for BN_div_recp() for numerators with an even number of
1750 bits.
1751 [Ulf M�ller]
1752
1753 *) More tests in bntest.c, and changed test_bn output.
1754 [Ulf M�ller]
1755
1756 *) ./config recognizes MacOS X now.
1757 [Andy Polyakov]
1758
1759 *) Bug fix for BN_div() when the first words of num and divsor are
1760 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
1761 [Ulf M�ller]
1762
1763 *) Add support for various broken PKCS#8 formats, and command line
1764 options to produce them.
1765 [Steve Henson]
1766
1767 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
1768 get temporary BIGNUMs from a BN_CTX.
1769 [Ulf M�ller]
1770
1771 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
1772 for p == 0.
1773 [Ulf M�ller]
1774
1775 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
1776 include a #define from the old name to the new. The original intent
1777 was that statically linked binaries could for example just call
1778 SSLeay_add_all_ciphers() to just add ciphers to the table and not
1779 link with digests. This never worked becayse SSLeay_add_all_digests()
1780 and SSLeay_add_all_ciphers() were in the same source file so calling
1781 one would link with the other. They are now in separate source files.
1782 [Steve Henson]
1783
1784 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
1785 [Steve Henson]
1786
1787 *) Use a less unusual form of the Miller-Rabin primality test (it used
1788 a binary algorithm for exponentiation integrated into the Miller-Rabin
1789 loop, our standard modexp algorithms are faster).
1790 [Bodo Moeller]
1791
1792 *) Support for the EBCDIC character set completed.
1793 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
1794
1795 *) Source code cleanups: use const where appropriate, eliminate casts,
1796 use void * instead of char * in lhash.
1797 [Ulf M�ller]
1798
1799 *) Bugfix: ssl3_send_server_key_exchange was not restartable
1800 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
1801 this the server could overwrite ephemeral keys that the client
1802 has already seen).
1803 [Bodo Moeller]
1804
1805 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
1806 using 50 iterations of the Rabin-Miller test.
1807
1808 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
1809 iterations of the Rabin-Miller test as required by the appendix
1810 to FIPS PUB 186[-1]) instead of DSA_is_prime.
1811 As BN_is_prime_fasttest includes trial division, DSA parameter
1812 generation becomes much faster.
1813
1814 This implies a change for the callback functions in DSA_is_prime
1815 and DSA_generate_parameters: The callback function is called once
1816 for each positive witness in the Rabin-Miller test, not just
1817 occasionally in the inner loop; and the parameters to the
1818 callback function now provide an iteration count for the outer
1819 loop rather than for the current invocation of the inner loop.
1820 DSA_generate_parameters additionally can call the callback
1821 function with an 'iteration count' of -1, meaning that a
1822 candidate has passed the trial division test (when q is generated
1823 from an application-provided seed, trial division is skipped).
1824 [Bodo Moeller]
1825
1826 *) New function BN_is_prime_fasttest that optionally does trial
1827 division before starting the Rabin-Miller test and has
1828 an additional BN_CTX * argument (whereas BN_is_prime always
1829 has to allocate at least one BN_CTX).
1830 'callback(1, -1, cb_arg)' is called when a number has passed the
1831 trial division stage.
1832 [Bodo Moeller]
1833
1834 *) Fix for bug in CRL encoding. The validity dates weren't being handled
1835 as ASN1_TIME.
1836 [Steve Henson]
1837
1838 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
1839 [Steve Henson]
1840
1841 *) New function BN_pseudo_rand().
1842 [Ulf M�ller]
1843
1844 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
1845 bignum version of BN_from_montgomery() with the working code from
1846 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
1847 the comments.
1848 [Ulf M�ller]
1849
1850 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
1851 made it impossible to use the same SSL_SESSION data structure in
1852 SSL2 clients in multiple threads.
1853 [Bodo Moeller]
1854
1855 *) The return value of RAND_load_file() no longer counts bytes obtained
1856 by stat(). RAND_load_file(..., -1) is new and uses the complete file
1857 to seed the PRNG (previously an explicit byte count was required).
1858 [Ulf M�ller, Bodo M�ller]
1859
1860 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
1861 used (char *) instead of (void *) and had casts all over the place.
1862 [Steve Henson]
1863
1864 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
1865 [Ulf M�ller]
1866
1867 *) Retain source code compatibility for BN_prime_checks macro:
1868 BN_is_prime(..., BN_prime_checks, ...) now uses
1869 BN_prime_checks_for_size to determine the appropriate number of
1870 Rabin-Miller iterations.
1871 [Ulf M�ller]
1872
1873 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
1874 DH_CHECK_P_NOT_SAFE_PRIME.
1875 (Check if this is true? OpenPGP calls them "strong".)
1876 [Ulf M�ller]
1877
1878 *) Merge the functionality of "dh" and "gendh" programs into a new program
1879 "dhparam". The old programs are retained for now but will handle DH keys
1880 (instead of parameters) in future.
1881 [Steve Henson]
1882
1883 *) Make the ciphers, s_server and s_client programs check the return values
1884 when a new cipher list is set.
1885 [Steve Henson]
1886
1887 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
1888 ciphers. Before when the 56bit ciphers were enabled the sorting was
1889 wrong.
1890
1891 The syntax for the cipher sorting has been extended to support sorting by
1892 cipher-strength (using the strength_bits hard coded in the tables).
1893 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
1894
1895 Fix a bug in the cipher-command parser: when supplying a cipher command
1896 string with an "undefined" symbol (neither command nor alphanumeric
1897 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
1898 an error is flagged.
1899
1900 Due to the strength-sorting extension, the code of the
1901 ssl_create_cipher_list() function was completely rearranged. I hope that
1902 the readability was also increased :-)
1903 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1904
1905 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
1906 for the first serial number and places 2 in the serial number file. This
1907 avoids problems when the root CA is created with serial number zero and
1908 the first user certificate has the same issuer name and serial number
1909 as the root CA.
1910 [Steve Henson]
1911
1912 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1913 the new code. Add documentation for this stuff.
1914 [Steve Henson]
1915
1916 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1917 X509_*() to X509at_*() on the grounds that they don't handle X509
1918 structures and behave in an analagous way to the X509v3 functions:
1919 they shouldn't be called directly but wrapper functions should be used
1920 instead.
1921
1922 So we also now have some wrapper functions that call the X509at functions
1923 when passed certificate requests. (TO DO: similar things can be done with
1924 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1925 things. Some of these need some d2i or i2d and print functionality
1926 because they handle more complex structures.)
1927 [Steve Henson]
1928
1929 *) Add missing #ifndefs that caused missing symbols when building libssl
1930 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1931 NO_RSA in ssl/s2*.c.
1932 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf M�ller]
1933
1934 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1935 has a return value which indicates the quality of the random data
1936 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1937 error queue. New function RAND_pseudo_bytes() generates output that is
1938 guaranteed to be unique but not unpredictable. RAND_add is like
1939 RAND_seed, but takes an extra argument for an entropy estimate
1940 (RAND_seed always assumes full entropy).
1941 [Ulf M�ller]
1942
1943 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1944 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1945 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1946 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1947 false-positive rate of at most 2^-80 for random input.
1948 [Bodo Moeller]
1949
1950 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1951 [Bodo Moeller]
1952
1953 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1954 in the 0.9.5 release), this returns the chain
1955 from an X509_CTX structure with a dup of the stack and all
1956 the X509 reference counts upped: so the stack will exist
1957 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1958 to use this.
1959
1960 Also make SSL_SESSION_print() print out the verify return
1961 code.
1962 [Steve Henson]
1963
1964 *) Add manpage for the pkcs12 command. Also change the default
1965 behaviour so MAC iteration counts are used unless the new
1966 -nomaciter option is used. This improves file security and
1967 only older versions of MSIE (4.0 for example) need it.
1968 [Steve Henson]
1969
1970 *) Honor the no-xxx Configure options when creating .DEF files.
1971 [Ulf M�ller]
1972
1973 *) Add PKCS#10 attributes to field table: challengePassword,
1974 unstructuredName and unstructuredAddress. These are taken from
1975 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1976 international characters are used.
1977
1978 More changes to X509_ATTRIBUTE code: allow the setting of types
1979 based on strings. Remove the 'loc' parameter when adding
1980 attributes because these will be a SET OF encoding which is sorted
1981 in ASN1 order.
1982 [Steve Henson]
1983
1984 *) Initial changes to the 'req' utility to allow request generation
1985 automation. This will allow an application to just generate a template
1986 file containing all the field values and have req construct the
1987 request.
1988
1989 Initial support for X509_ATTRIBUTE handling. Stacks of these are
1990 used all over the place including certificate requests and PKCS#7
1991 structures. They are currently handled manually where necessary with
1992 some primitive wrappers for PKCS#7. The new functions behave in a
1993 manner analogous to the X509 extension functions: they allow
1994 attributes to be looked up by NID and added.
1995
1996 Later something similar to the X509V3 code would be desirable to
1997 automatically handle the encoding, decoding and printing of the
1998 more complex types. The string types like challengePassword can
1999 be handled by the string table functions.
2000
2001 Also modified the multi byte string table handling. Now there is
2002 a 'global mask' which masks out certain types. The table itself
2003 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2004 is useful when for example there is only one permissible type
2005 (as in countryName) and using the mask might result in no valid
2006 types at all.
2007 [Steve Henson]
2008
2009 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2010 SSL_get_peer_finished to allow applications to obtain the latest
2011 Finished messages sent to the peer or expected from the peer,
2012 respectively. (SSL_get_peer_finished is usually the Finished message
2013 actually received from the peer, otherwise the protocol will be aborted.)
2014
2015 As the Finished message are message digests of the complete handshake
2016 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2017 be used for external authentication procedures when the authentication
2018 provided by SSL/TLS is not desired or is not enough.
2019 [Bodo Moeller]
2020
2021 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2022 the host supports BWX extension and if Compaq C is present on the
2023 $PATH. Just exploiting of the BWX extension results in 20-30%
2024 performance kick for some algorithms, e.g. DES and RC4 to mention
2025 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2026 SHA1.
2027 [Andy Polyakov]
2028
2029 *) Add support for MS "fast SGC". This is arguably a violation of the
2030 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2031 weak crypto and after checking the certificate is SGC a second one
2032 with strong crypto. MS SGC stops the first handshake after receiving
2033 the server certificate message and sends a second client hello. Since
2034 a server will typically do all the time consuming operations before
2035 expecting any further messages from the client (server key exchange
2036 is the most expensive) there is little difference between the two.
2037
2038 To get OpenSSL to support MS SGC we have to permit a second client
2039 hello message after we have sent server done. In addition we have to
2040 reset the MAC if we do get this second client hello.
2041 [Steve Henson]
2042
2043 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
2044 if a DER encoded private key is RSA or DSA traditional format. Changed
2045 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
2046 format DER encoded private key. Newer code should use PKCS#8 format which
2047 has the key type encoded in the ASN1 structure. Added DER private key
2048 support to pkcs8 application.
2049 [Steve Henson]
2050
2051 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
2052 ciphersuites has been selected (as required by the SSL 3/TLS 1
2053 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
2054 is set, we interpret this as a request to violate the specification
2055 (the worst that can happen is a handshake failure, and 'correct'
2056 behaviour would result in a handshake failure anyway).
2057 [Bodo Moeller]
2058
2059 *) In SSL_CTX_add_session, take into account that there might be multiple
2060 SSL_SESSION structures with the same session ID (e.g. when two threads
2061 concurrently obtain them from an external cache).
2062 The internal cache can handle only one SSL_SESSION with a given ID,
2063 so if there's a conflict, we now throw out the old one to achieve
2064 consistency.
2065 [Bodo Moeller]
2066
2067 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
2068 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
2069 some routines that use cipher OIDs: some ciphers do not have OIDs
2070 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
2071 example.
2072 [Steve Henson]
2073
2074 *) Simplify the trust setting structure and code. Now we just have
2075 two sequences of OIDs for trusted and rejected settings. These will
2076 typically have values the same as the extended key usage extension
2077 and any application specific purposes.
2078
2079 The trust checking code now has a default behaviour: it will just
2080 check for an object with the same NID as the passed id. Functions can
2081 be provided to override either the default behaviour or the behaviour
2082 for a given id. SSL client, server and email already have functions
2083 in place for compatibility: they check the NID and also return "trusted"
2084 if the certificate is self signed.
2085 [Steve Henson]
2086
2087 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
2088 traditional format into an EVP_PKEY structure.
2089 [Steve Henson]
2090
2091 *) Add a password callback function PEM_cb() which either prompts for
2092 a password if usr_data is NULL or otherwise assumes it is a null
2093 terminated password. Allow passwords to be passed on command line
2094 environment or config files in a few more utilities.
2095 [Steve Henson]
2096
2097 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
2098 keys. Add some short names for PKCS#8 PBE algorithms and allow them
2099 to be specified on the command line for the pkcs8 and pkcs12 utilities.
2100 Update documentation.
2101 [Steve Henson]
2102
2103 *) Support for ASN1 "NULL" type. This could be handled before by using
2104 ASN1_TYPE but there wasn't any function that would try to read a NULL
2105 and produce an error if it couldn't. For compatibility we also have
2106 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
2107 don't allocate anything because they don't need to.
2108 [Steve Henson]
2109
2110 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
2111 for details.
2112 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
2113
2114 *) Rebuild of the memory allocation routines used by OpenSSL code and
2115 possibly others as well. The purpose is to make an interface that
2116 provide hooks so anyone can build a separate set of allocation and
2117 deallocation routines to be used by OpenSSL, for example memory
2118 pool implementations, or something else, which was previously hard
2119 since Malloc(), Realloc() and Free() were defined as macros having
2120 the values malloc, realloc and free, respectively (except for Win32
2121 compilations). The same is provided for memory debugging code.
2122 OpenSSL already comes with functionality to find memory leaks, but
2123 this gives people a chance to debug other memory problems.
2124
2125 With these changes, a new set of functions and macros have appeared:
2126
2127 CRYPTO_set_mem_debug_functions() [F]
2128 CRYPTO_get_mem_debug_functions() [F]
2129 CRYPTO_dbg_set_options() [F]
2130 CRYPTO_dbg_get_options() [F]
2131 CRYPTO_malloc_debug_init() [M]
2132
2133 The memory debug functions are NULL by default, unless the library
2134 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
2135 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
2136 gives the standard debugging functions that come with OpenSSL) or
2137 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
2138 provided by the library user) must be used. When the standard
2139 debugging functions are used, CRYPTO_dbg_set_options can be used to
2140 request additional information:
2141 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
2142 the CRYPTO_MDEBUG_xxx macro when compiling the library.
2143
2144 Also, things like CRYPTO_set_mem_functions will always give the
2145 expected result (the new set of functions is used for allocation
2146 and deallocation) at all times, regardless of platform and compiler
2147 options.
2148
2149 To finish it up, some functions that were never use in any other
2150 way than through macros have a new API and new semantic:
2151
2152 CRYPTO_dbg_malloc()
2153 CRYPTO_dbg_realloc()
2154 CRYPTO_dbg_free()
2155
2156 All macros of value have retained their old syntax.
2157 [Richard Levitte and Bodo Moeller]
2158
2159 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
2160 ordering of SMIMECapabilities wasn't in "strength order" and there
2161 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
2162 algorithm.
2163 [Steve Henson]
2164
2165 *) Some ASN1 types with illegal zero length encoding (INTEGER,
2166 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
2167 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
2168
2169 *) Merge in my S/MIME library for OpenSSL. This provides a simple
2170 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
2171 functionality to handle multipart/signed properly) and a utility
2172 called 'smime' to call all this stuff. This is based on code I
2173 originally wrote for Celo who have kindly allowed it to be
2174 included in OpenSSL.
2175 [Steve Henson]
2176
2177 *) Add variants des_set_key_checked and des_set_key_unchecked of
2178 des_set_key (aka des_key_sched). Global variable des_check_key
2179 decides which of these is called by des_set_key; this way
2180 des_check_key behaves as it always did, but applications and
2181 the library itself, which was buggy for des_check_key == 1,
2182 have a cleaner way to pick the version they need.
2183 [Bodo Moeller]
2184
2185 *) New function PKCS12_newpass() which changes the password of a
2186 PKCS12 structure.
2187 [Steve Henson]
2188
2189 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
2190 dynamic mix. In both cases the ids can be used as an index into the
2191 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
2192 functions so they accept a list of the field values and the
2193 application doesn't need to directly manipulate the X509_TRUST
2194 structure.
2195 [Steve Henson]
2196
2197 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
2198 need initialising.
2199 [Steve Henson]
2200
2201 *) Modify the way the V3 extension code looks up extensions. This now
2202 works in a similar way to the object code: we have some "standard"
2203 extensions in a static table which is searched with OBJ_bsearch()
2204 and the application can add dynamic ones if needed. The file
2205 crypto/x509v3/ext_dat.h now has the info: this file needs to be
2206 updated whenever a new extension is added to the core code and kept
2207 in ext_nid order. There is a simple program 'tabtest.c' which checks
2208 this. New extensions are not added too often so this file can readily
2209 be maintained manually.
2210
2211 There are two big advantages in doing things this way. The extensions
2212 can be looked up immediately and no longer need to be "added" using
2213 X509V3_add_standard_extensions(): this function now does nothing.
2214 [Side note: I get *lots* of email saying the extension code doesn't
2215 work because people forget to call this function]
2216 Also no dynamic allocation is done unless new extensions are added:
2217 so if we don't add custom extensions there is no need to call
2218 X509V3_EXT_cleanup().
2219 [Steve Henson]
2220
2221 *) Modify enc utility's salting as follows: make salting the default. Add a
2222 magic header, so unsalted files fail gracefully instead of just decrypting
2223 to garbage. This is because not salting is a big security hole, so people
2224 should be discouraged from doing it.
2225 [Ben Laurie]
2226
2227 *) Fixes and enhancements to the 'x509' utility. It allowed a message
2228 digest to be passed on the command line but it only used this
2229 parameter when signing a certificate. Modified so all relevant
2230 operations are affected by the digest parameter including the
2231 -fingerprint and -x509toreq options. Also -x509toreq choked if a
2232 DSA key was used because it didn't fix the digest.
2233 [Steve Henson]
2234
2235 *) Initial certificate chain verify code. Currently tests the untrusted
2236 certificates for consistency with the verify purpose (which is set
2237 when the X509_STORE_CTX structure is set up) and checks the pathlength.
2238
2239 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
2240 this is because it will reject chains with invalid extensions whereas
2241 every previous version of OpenSSL and SSLeay made no checks at all.
2242
2243 Trust code: checks the root CA for the relevant trust settings. Trust
2244 settings have an initial value consistent with the verify purpose: e.g.
2245 if the verify purpose is for SSL client use it expects the CA to be
2246 trusted for SSL client use. However the default value can be changed to
2247 permit custom trust settings: one example of this would be to only trust
2248 certificates from a specific "secure" set of CAs.
2249
2250 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
2251 which should be used for version portability: especially since the
2252 verify structure is likely to change more often now.
2253
2254 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
2255 to set them. If not set then assume SSL clients will verify SSL servers
2256 and vice versa.
2257
2258 Two new options to the verify program: -untrusted allows a set of
2259 untrusted certificates to be passed in and -purpose which sets the
2260 intended purpose of the certificate. If a purpose is set then the
2261 new chain verify code is used to check extension consistency.
2262 [Steve Henson]
2263
2264 *) Support for the authority information access extension.
2265 [Steve Henson]
2266
2267 *) Modify RSA and DSA PEM read routines to transparently handle
2268 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
2269 public keys in a format compatible with certificate
2270 SubjectPublicKeyInfo structures. Unfortunately there were already
2271 functions called *_PublicKey_* which used various odd formats so
2272 these are retained for compatibility: however the DSA variants were
2273 never in a public release so they have been deleted. Changed dsa/rsa
2274 utilities to handle the new format: note no releases ever handled public
2275 keys so we should be OK.
2276
2277 The primary motivation for this change is to avoid the same fiasco
2278 that dogs private keys: there are several incompatible private key
2279 formats some of which are standard and some OpenSSL specific and
2280 require various evil hacks to allow partial transparent handling and
2281 even then it doesn't work with DER formats. Given the option anything
2282 other than PKCS#8 should be dumped: but the other formats have to
2283 stay in the name of compatibility.
2284
2285 With public keys and the benefit of hindsight one standard format
2286 is used which works with EVP_PKEY, RSA or DSA structures: though
2287 it clearly returns an error if you try to read the wrong kind of key.
2288
2289 Added a -pubkey option to the 'x509' utility to output the public key.
2290 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
2291 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
2292 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
2293 that do the same as the EVP_PKEY_assign_*() except they up the
2294 reference count of the added key (they don't "swallow" the
2295 supplied key).
2296 [Steve Henson]
2297
2298 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
2299 CRLs would fail if the file contained no certificates or no CRLs:
2300 added a new function to read in both types and return the number
2301 read: this means that if none are read it will be an error. The
2302 DER versions of the certificate and CRL reader would always fail
2303 because it isn't possible to mix certificates and CRLs in DER format
2304 without choking one or the other routine. Changed this to just read
2305 a certificate: this is the best we can do. Also modified the code
2306 in apps/verify.c to take notice of return codes: it was previously
2307 attempting to read in certificates from NULL pointers and ignoring
2308 any errors: this is one reason why the cert and CRL reader seemed
2309 to work. It doesn't check return codes from the default certificate
2310 routines: these may well fail if the certificates aren't installed.
2311 [Steve Henson]
2312
2313 *) Code to support otherName option in GeneralName.
2314 [Steve Henson]
2315
2316 *) First update to verify code. Change the verify utility
2317 so it warns if it is passed a self signed certificate:
2318 for consistency with the normal behaviour. X509_verify
2319 has been modified to it will now verify a self signed
2320 certificate if *exactly* the same certificate appears
2321 in the store: it was previously impossible to trust a
2322 single self signed certificate. This means that:
2323 openssl verify ss.pem
2324 now gives a warning about a self signed certificate but
2325 openssl verify -CAfile ss.pem ss.pem
2326 is OK.
2327 [Steve Henson]
2328
2329 *) For servers, store verify_result in SSL_SESSION data structure
2330 (and add it to external session representation).
2331 This is needed when client certificate verifications fails,
2332 but an application-provided verification callback (set by
2333 SSL_CTX_set_cert_verify_callback) allows accepting the session
2334 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
2335 but returns 1): When the session is reused, we have to set
2336 ssl->verify_result to the appropriate error code to avoid
2337 security holes.
2338 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
2339
2340 *) Fix a bug in the new PKCS#7 code: it didn't consider the
2341 case in PKCS7_dataInit() where the signed PKCS7 structure
2342 didn't contain any existing data because it was being created.
2343 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
2344
2345 *) Add a salt to the key derivation routines in enc.c. This
2346 forms the first 8 bytes of the encrypted file. Also add a
2347 -S option to allow a salt to be input on the command line.
2348 [Steve Henson]
2349
2350 *) New function X509_cmp(). Oddly enough there wasn't a function
2351 to compare two certificates. We do this by working out the SHA1
2352 hash and comparing that. X509_cmp() will be needed by the trust
2353 code.
2354 [Steve Henson]
2355
2356 *) SSL_get1_session() is like SSL_get_session(), but increments
2357 the reference count in the SSL_SESSION returned.
2358 [Geoff Thorpe <geoff@eu.c2.net>]
2359
2360 *) Fix for 'req': it was adding a null to request attributes.
2361 Also change the X509_LOOKUP and X509_INFO code to handle
2362 certificate auxiliary information.
2363 [Steve Henson]
2364
2365 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
2366 the 'enc' command.
2367 [Steve Henson]
2368
2369 *) Add the possibility to add extra information to the memory leak
2370 detecting output, to form tracebacks, showing from where each
2371 allocation was originated: CRYPTO_push_info("constant string") adds
2372 the string plus current file name and line number to a per-thread
2373 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
2374 is like calling CYRPTO_pop_info() until the stack is empty.
2375 Also updated memory leak detection code to be multi-thread-safe.
2376 [Richard Levitte]
2377
2378 *) Add options -text and -noout to pkcs7 utility and delete the
2379 encryption options which never did anything. Update docs.
2380 [Steve Henson]
2381
2382 *) Add options to some of the utilities to allow the pass phrase
2383 to be included on either the command line (not recommended on
2384 OSes like Unix) or read from the environment. Update the
2385 manpages and fix a few bugs.
2386 [Steve Henson]
2387
2388 *) Add a few manpages for some of the openssl commands.
2389 [Steve Henson]
2390
2391 *) Fix the -revoke option in ca. It was freeing up memory twice,
2392 leaking and not finding already revoked certificates.
2393 [Steve Henson]
2394
2395 *) Extensive changes to support certificate auxiliary information.
2396 This involves the use of X509_CERT_AUX structure and X509_AUX
2397 functions. An X509_AUX function such as PEM_read_X509_AUX()
2398 can still read in a certificate file in the usual way but it
2399 will also read in any additional "auxiliary information". By
2400 doing things this way a fair degree of compatibility can be
2401 retained: existing certificates can have this information added
2402 using the new 'x509' options.
2403
2404 Current auxiliary information includes an "alias" and some trust
2405 settings. The trust settings will ultimately be used in enhanced
2406 certificate chain verification routines: currently a certificate
2407 can only be trusted if it is self signed and then it is trusted
2408 for all purposes.
2409 [Steve Henson]
2410
2411 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
2412 The problem was that one of the replacement routines had not been working
2413 since SSLeay releases. For now the offending routine has been replaced
2414 with non-optimised assembler. Even so, this now gives around 95%
2415 performance improvement for 1024 bit RSA signs.
2416 [Mark Cox]
2417
2418 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
2419 handling. Most clients have the effective key size in bits equal to
2420 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
2421 A few however don't do this and instead use the size of the decrypted key
2422 to determine the RC2 key length and the AlgorithmIdentifier to determine
2423 the effective key length. In this case the effective key length can still
2424 be 40 bits but the key length can be 168 bits for example. This is fixed
2425 by manually forcing an RC2 key into the EVP_PKEY structure because the
2426 EVP code can't currently handle unusual RC2 key sizes: it always assumes
2427 the key length and effective key length are equal.
2428 [Steve Henson]
2429
2430 *) Add a bunch of functions that should simplify the creation of
2431 X509_NAME structures. Now you should be able to do:
2432 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
2433 and have it automatically work out the correct field type and fill in
2434 the structures. The more adventurous can try:
2435 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
2436 and it will (hopefully) work out the correct multibyte encoding.
2437 [Steve Henson]
2438
2439 *) Change the 'req' utility to use the new field handling and multibyte
2440 copy routines. Before the DN field creation was handled in an ad hoc
2441 way in req, ca, and x509 which was rather broken and didn't support
2442 BMPStrings or UTF8Strings. Since some software doesn't implement
2443 BMPStrings or UTF8Strings yet, they can be enabled using the config file
2444 using the dirstring_type option. See the new comment in the default
2445 openssl.cnf for more info.
2446 [Steve Henson]
2447
2448 *) Make crypto/rand/md_rand.c more robust:
2449 - Assure unique random numbers after fork().
2450 - Make sure that concurrent threads access the global counter and
2451 md serializably so that we never lose entropy in them
2452 or use exactly the same state in multiple threads.
2453 Access to the large state is not always serializable because
2454 the additional locking could be a performance killer, and
2455 md should be large enough anyway.
2456 [Bodo Moeller]
2457
2458 *) New file apps/app_rand.c with commonly needed functionality
2459 for handling the random seed file.
2460
2461 Use the random seed file in some applications that previously did not:
2462 ca,
2463 dsaparam -genkey (which also ignored its '-rand' option),
2464 s_client,
2465 s_server,
2466 x509 (when signing).
2467 Except on systems with /dev/urandom, it is crucial to have a random
2468 seed file at least for key creation, DSA signing, and for DH exchanges;
2469 for RSA signatures we could do without one.
2470
2471 gendh and gendsa (unlike genrsa) used to read only the first byte
2472 of each file listed in the '-rand' option. The function as previously
2473 found in genrsa is now in app_rand.c and is used by all programs
2474 that support '-rand'.
2475 [Bodo Moeller]
2476
2477 *) In RAND_write_file, use mode 0600 for creating files;
2478 don't just chmod when it may be too late.
2479 [Bodo Moeller]
2480
2481 *) Report an error from X509_STORE_load_locations
2482 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
2483 [Bill Perry]
2484
2485 *) New function ASN1_mbstring_copy() this copies a string in either
2486 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
2487 into an ASN1_STRING type. A mask of permissible types is passed
2488 and it chooses the "minimal" type to use or an error if not type
2489 is suitable.
2490 [Steve Henson]
2491
2492 *) Add function equivalents to the various macros in asn1.h. The old
2493 macros are retained with an M_ prefix. Code inside the library can
2494 use the M_ macros. External code (including the openssl utility)
2495 should *NOT* in order to be "shared library friendly".
2496 [Steve Henson]
2497
2498 *) Add various functions that can check a certificate's extensions
2499 to see if it usable for various purposes such as SSL client,
2500 server or S/MIME and CAs of these types. This is currently
2501 VERY EXPERIMENTAL but will ultimately be used for certificate chain
2502 verification. Also added a -purpose flag to x509 utility to
2503 print out all the purposes.
2504 [Steve Henson]
2505
2506 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
2507 functions.
2508 [Steve Henson]
2509
2510 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
2511 for, obtain and decode and extension and obtain its critical flag.
2512 This allows all the necessary extension code to be handled in a
2513 single function call.
2514 [Steve Henson]
2515
2516 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
2517 platforms. See crypto/rc4/rc4_enc.c for further details.
2518 [Andy Polyakov]
2519
2520 *) New -noout option to asn1parse. This causes no output to be produced
2521 its main use is when combined with -strparse and -out to extract data
2522 from a file (which may not be in ASN.1 format).
2523 [Steve Henson]
2524
2525 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2526 when producing the local key id.
2527 [Richard Levitte <levitte@stacken.kth.se>]
2528
2529 *) New option -dhparam in s_server. This allows a DH parameter file to be
2530 stated explicitly. If it is not stated then it tries the first server
2531 certificate file. The previous behaviour hard coded the filename
2532 "server.pem".
2533 [Steve Henson]
2534
2535 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
2536 a public key to be input or output. For example:
2537 openssl rsa -in key.pem -pubout -out pubkey.pem
2538 Also added necessary DSA public key functions to handle this.
2539 [Steve Henson]
2540
2541 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
2542 in the message. This was handled by allowing
2543 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
2544 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
2545
2546 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
2547 to the end of the strings whereas this didn't. This would cause problems
2548 if strings read with d2i_ASN1_bytes() were later modified.
2549 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
2550
2551 *) Fix for base64 decode bug. When a base64 bio reads only one line of
2552 data and it contains EOF it will end up returning an error. This is
2553 caused by input 46 bytes long. The cause is due to the way base64
2554 BIOs find the start of base64 encoded data. They do this by trying a
2555 trial decode on each line until they find one that works. When they
2556 do a flag is set and it starts again knowing it can pass all the
2557 data directly through the decoder. Unfortunately it doesn't reset
2558 the context it uses. This means that if EOF is reached an attempt
2559 is made to pass two EOFs through the context and this causes the
2560 resulting error. This can also cause other problems as well. As is
2561 usual with these problems it takes *ages* to find and the fix is
2562 trivial: move one line.
2563 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
2564
2565 *) Ugly workaround to get s_client and s_server working under Windows. The
2566 old code wouldn't work because it needed to select() on sockets and the
2567 tty (for keypresses and to see if data could be written). Win32 only
2568 supports select() on sockets so we select() with a 1s timeout on the
2569 sockets and then see if any characters are waiting to be read, if none
2570 are present then we retry, we also assume we can always write data to
2571 the tty. This isn't nice because the code then blocks until we've
2572 received a complete line of data and it is effectively polling the
2573 keyboard at 1s intervals: however it's quite a bit better than not
2574 working at all :-) A dedicated Windows application might handle this
2575 with an event loop for example.
2576 [Steve Henson]
2577
2578 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
2579 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
2580 will be called when RSA_sign() and RSA_verify() are used. This is useful
2581 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
2582 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
2583 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2584 This necessitated the support of an extra signature type NID_md5_sha1
2585 for SSL signatures and modifications to the SSL library to use it instead
2586 of calling RSA_public_decrypt() and RSA_private_encrypt().
2587 [Steve Henson]
2588
2589 *) Add new -verify -CAfile and -CApath options to the crl program, these
2590 will lookup a CRL issuers certificate and verify the signature in a
2591 similar way to the verify program. Tidy up the crl program so it
2592 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2593 less strict. It will now permit CRL extensions even if it is not
2594 a V2 CRL: this will allow it to tolerate some broken CRLs.
2595 [Steve Henson]
2596
2597 *) Initialize all non-automatic variables each time one of the openssl
2598 sub-programs is started (this is necessary as they may be started
2599 multiple times from the "OpenSSL>" prompt).
2600 [Lennart Bang, Bodo Moeller]
2601
2602 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2603 removing all other RSA functionality (this is what NO_RSA does). This
2604 is so (for example) those in the US can disable those operations covered
2605 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2606 key generation.
2607 [Steve Henson]
2608
2609 *) Non-copying interface to BIO pairs.
2610 (still largely untested)
2611 [Bodo Moeller]
2612
2613 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2614 ASCII string. This was handled independently in various places before.
2615 [Steve Henson]
2616
2617 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2618 UTF8 strings a character at a time.
2619 [Steve Henson]
2620
2621 *) Use client_version from client hello to select the protocol
2622 (s23_srvr.c) and for RSA client key exchange verification
2623 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2624 [Bodo Moeller]
2625
2626 *) Add various utility functions to handle SPKACs, these were previously
2627 handled by poking round in the structure internals. Added new function
2628 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
2629 print, verify and generate SPKACs. Based on an original idea from
2630 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
2631 [Steve Henson]
2632
2633 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
2634 [Andy Polyakov]
2635
2636 *) Allow the config file extension section to be overwritten on the
2637 command line. Based on an original idea from Massimiliano Pala
2638 <madwolf@comune.modena.it>. The new option is called -extensions
2639 and can be applied to ca, req and x509. Also -reqexts to override
2640 the request extensions in req and -crlexts to override the crl extensions
2641 in ca.
2642 [Steve Henson]
2643
2644 *) Add new feature to the SPKAC handling in ca. Now you can include
2645 the same field multiple times by preceding it by "XXXX." for example:
2646 1.OU="Unit name 1"
2647 2.OU="Unit name 2"
2648 this is the same syntax as used in the req config file.
2649 [Steve Henson]
2650
2651 *) Allow certificate extensions to be added to certificate requests. These
2652 are specified in a 'req_extensions' option of the req section of the
2653 config file. They can be printed out with the -text option to req but
2654 are otherwise ignored at present.
2655 [Steve Henson]
2656
2657 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
2658 data read consists of only the final block it would not decrypted because
2659 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
2660 A misplaced 'break' also meant the decrypted final block might not be
2661 copied until the next read.
2662 [Steve Henson]
2663
2664 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
2665 a few extra parameters to the DH structure: these will be useful if
2666 for example we want the value of 'q' or implement X9.42 DH.
2667 [Steve Henson]
2668
2669 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
2670 provides hooks that allow the default DSA functions or functions on a
2671 "per key" basis to be replaced. This allows hardware acceleration and
2672 hardware key storage to be handled without major modification to the
2673 library. Also added low level modexp hooks and CRYPTO_EX structure and
2674 associated functions.
2675 [Steve Henson]
2676
2677 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
2678 as "read only": it can't be written to and the buffer it points to will
2679 not be freed. Reading from a read only BIO is much more efficient than
2680 a normal memory BIO. This was added because there are several times when
2681 an area of memory needs to be read from a BIO. The previous method was
2682 to create a memory BIO and write the data to it, this results in two
2683 copies of the data and an O(n^2) reading algorithm. There is a new
2684 function BIO_new_mem_buf() which creates a read only memory BIO from
2685 an area of memory. Also modified the PKCS#7 routines to use read only
2686 memory BIOs.
2687 [Steve Henson]
2688
2689 *) Bugfix: ssl23_get_client_hello did not work properly when called in
2690 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
2691 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
2692 but a retry condition occured while trying to read the rest.
2693 [Bodo Moeller]
2694
2695 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
2696 NID_pkcs7_encrypted by default: this was wrong since this should almost
2697 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
2698 the encrypted data type: this is a more sensible place to put it and it
2699 allows the PKCS#12 code to be tidied up that duplicated this
2700 functionality.
2701 [Steve Henson]
2702
2703 *) Changed obj_dat.pl script so it takes its input and output files on
2704 the command line. This should avoid shell escape redirection problems
2705 under Win32.
2706 [Steve Henson]
2707
2708 *) Initial support for certificate extension requests, these are included
2709 in things like Xenroll certificate requests. Included functions to allow
2710 extensions to be obtained and added.
2711 [Steve Henson]
2712
2713 *) -crlf option to s_client and s_server for sending newlines as
2714 CRLF (as required by many protocols).
2715 [Bodo Moeller]
2716
2717 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2718
2719 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2720 [Ralf S. Engelschall]
2721
2722 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
2723 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
2724
2725 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
2726 program.
2727 [Steve Henson]
2728
2729 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
2730 DH parameters/keys (q is lost during that conversion, but the resulting
2731 DH parameters contain its length).
2732
2733 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
2734 much faster than DH_generate_parameters (which creates parameters
2735 where p = 2*q + 1), and also the smaller q makes DH computations
2736 much more efficient (160-bit exponentiation instead of 1024-bit
2737 exponentiation); so this provides a convenient way to support DHE
2738 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
2739 utter importance to use
2740 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2741 or
2742 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2743 when such DH parameters are used, because otherwise small subgroup
2744 attacks may become possible!
2745 [Bodo Moeller]
2746
2747 *) Avoid memory leak in i2d_DHparams.
2748 [Bodo Moeller]
2749
2750 *) Allow the -k option to be used more than once in the enc program:
2751 this allows the same encrypted message to be read by multiple recipients.
2752 [Steve Henson]
2753
2754 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
2755 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
2756 it will always use the numerical form of the OID, even if it has a short
2757 or long name.
2758 [Steve Henson]
2759
2760 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
2761 method only got called if p,q,dmp1,dmq1,iqmp components were present,
2762 otherwise bn_mod_exp was called. In the case of hardware keys for example
2763 no private key components need be present and it might store extra data
2764 in the RSA structure, which cannot be accessed from bn_mod_exp.
2765 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
2766 private key operations.
2767 [Steve Henson]
2768
2769 *) Added support for SPARC Linux.
2770 [Andy Polyakov]
2771
2772 *) pem_password_cb function type incompatibly changed from
2773 typedef int pem_password_cb(char *buf, int size, int rwflag);
2774 to
2775 ....(char *buf, int size, int rwflag, void *userdata);
2776 so that applications can pass data to their callbacks:
2777 The PEM[_ASN1]_{read,write}... functions and macros now take an
2778 additional void * argument, which is just handed through whenever
2779 the password callback is called.
2780 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
2781
2782 New function SSL_CTX_set_default_passwd_cb_userdata.
2783
2784 Compatibility note: As many C implementations push function arguments
2785 onto the stack in reverse order, the new library version is likely to
2786 interoperate with programs that have been compiled with the old
2787 pem_password_cb definition (PEM_whatever takes some data that
2788 happens to be on the stack as its last argument, and the callback
2789 just ignores this garbage); but there is no guarantee whatsoever that
2790 this will work.
2791
2792 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
2793 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
2794 problems not only on Windows, but also on some Unix platforms.
2795 To avoid problematic command lines, these definitions are now in an
2796 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
2797 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
2798 [Bodo Moeller]
2799
2800 *) MIPS III/IV assembler module is reimplemented.
2801 [Andy Polyakov]
2802
2803 *) More DES library cleanups: remove references to srand/rand and
2804 delete an unused file.
2805 [Ulf M�ller]
2806
2807 *) Add support for the the free Netwide assembler (NASM) under Win32,
2808 since not many people have MASM (ml) and it can be hard to obtain.
2809 This is currently experimental but it seems to work OK and pass all
2810 the tests. Check out INSTALL.W32 for info.
2811 [Steve Henson]
2812
2813 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
2814 without temporary keys kept an extra copy of the server key,
2815 and connections with temporary keys did not free everything in case
2816 of an error.
2817 [Bodo Moeller]
2818
2819 *) New function RSA_check_key and new openssl rsa option -check
2820 for verifying the consistency of RSA keys.
2821 [Ulf Moeller, Bodo Moeller]
2822
2823 *) Various changes to make Win32 compile work:
2824 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2825 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
2826 comparison" warnings.
2827 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
2828 [Steve Henson]
2829
2830 *) Add a debugging option to PKCS#5 v2 key generation function: when
2831 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
2832 derived keys are printed to stderr.
2833 [Steve Henson]
2834
2835 *) Copy the flags in ASN1_STRING_dup().
2836 [Roman E. Pavlov <pre@mo.msk.ru>]
2837
2838 *) The x509 application mishandled signing requests containing DSA
2839 keys when the signing key was also DSA and the parameters didn't match.
2840
2841 It was supposed to omit the parameters when they matched the signing key:
2842 the verifying software was then supposed to automatically use the CA's
2843 parameters if they were absent from the end user certificate.
2844
2845 Omitting parameters is no longer recommended. The test was also
2846 the wrong way round! This was probably due to unusual behaviour in
2847 EVP_cmp_parameters() which returns 1 if the parameters match.
2848 This meant that parameters were omitted when they *didn't* match and
2849 the certificate was useless. Certificates signed with 'ca' didn't have
2850 this bug.
2851 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
2852
2853 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
2854 The interface is as follows:
2855 Applications can use
2856 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
2857 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
2858 "off" is now the default.
2859 The library internally uses
2860 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
2861 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
2862 to disable memory-checking temporarily.
2863
2864 Some inconsistent states that previously were possible (and were
2865 even the default) are now avoided.
2866
2867 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
2868 with each memory chunk allocated; this is occasionally more helpful
2869 than just having a counter.
2870
2871 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
2872
2873 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
2874 extensions.
2875 [Bodo Moeller]
2876
2877 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
2878 which largely parallels "options", but is for changing API behaviour,
2879 whereas "options" are about protocol behaviour.
2880 Initial "mode" flags are:
2881
2882 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
2883 a single record has been written.
2884 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
2885 retries use the same buffer location.
2886 (But all of the contents must be
2887 copied!)
2888 [Bodo Moeller]
2889
2890 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
2891 worked.
2892
2893 *) Fix problems with no-hmac etc.
2894 [Ulf M�ller, pointed out by Brian Wellington <bwelling@tislabs.com>]
2895
2896 *) New functions RSA_get_default_method(), RSA_set_method() and
2897 RSA_get_method(). These allows replacement of RSA_METHODs without having
2898 to mess around with the internals of an RSA structure.
2899 [Steve Henson]
2900
2901 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
2902 Also really enable memory leak checks in openssl.c and in some
2903 test programs.
2904 [Chad C. Mulligan, Bodo Moeller]
2905
2906 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
2907 up the length of negative integers. This has now been simplified to just
2908 store the length when it is first determined and use it later, rather
2909 than trying to keep track of where data is copied and updating it to
2910 point to the end.
2911 [Steve Henson, reported by Brien Wheeler
2912 <bwheeler@authentica-security.com>]
2913
2914 *) Add a new function PKCS7_signatureVerify. This allows the verification
2915 of a PKCS#7 signature but with the signing certificate passed to the
2916 function itself. This contrasts with PKCS7_dataVerify which assumes the
2917 certificate is present in the PKCS#7 structure. This isn't always the
2918 case: certificates can be omitted from a PKCS#7 structure and be
2919 distributed by "out of band" means (such as a certificate database).
2920 [Steve Henson]
2921
2922 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2923 function prototypes in pem.h, also change util/mkdef.pl to add the
2924 necessary function names.
2925 [Steve Henson]
2926
2927 *) mk1mf.pl (used by Windows builds) did not properly read the
2928 options set by Configure in the top level Makefile, and Configure
2929 was not even able to write more than one option correctly.
2930 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2931 [Bodo Moeller]
2932
2933 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2934 file to be loaded from a BIO or FILE pointer. The BIO version will
2935 for example allow memory BIOs to contain config info.
2936 [Steve Henson]
2937
2938 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2939 Whoever hopes to achieve shared-library compatibility across versions
2940 must use this, not the compile-time macro.
2941 (Exercise 0.9.4: Which is the minimum library version required by
2942 such programs?)
2943 Note: All this applies only to multi-threaded programs, others don't
2944 need locks.
2945 [Bodo Moeller]
2946
2947 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2948 through a BIO pair triggered the default case, i.e.
2949 SSLerr(...,SSL_R_UNKNOWN_STATE).
2950 [Bodo Moeller]
2951
2952 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2953 can use the SSL library even if none of the specific BIOs is
2954 appropriate.
2955 [Bodo Moeller]
2956
2957 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2958 for the encoded length.
2959 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2960
2961 *) Add initial documentation of the X509V3 functions.
2962 [Steve Henson]
2963
2964 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2965 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2966 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2967 secure PKCS#8 private key format with a high iteration count.
2968 [Steve Henson]
2969
2970 *) Fix determination of Perl interpreter: A perl or perl5
2971 _directory_ in $PATH was also accepted as the interpreter.
2972 [Ralf S. Engelschall]
2973
2974 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2975 wrong with it but it was very old and did things like calling
2976 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2977 unusual formatting.
2978 [Steve Henson]
2979
2980 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2981 to use the new extension code.
2982 [Steve Henson]
2983
2984 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2985 with macros. This should make it easier to change their form, add extra
2986 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
2987 constant.
2988 [Steve Henson]
2989
2990 *) Add to configuration table a new entry that can specify an alternative
2991 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
2992 according to Mark Crispin <MRC@Panda.COM>.
2993 [Bodo Moeller]
2994
2995#if 0
2996 *) DES CBC did not update the IV. Weird.
2997 [Ben Laurie]
2998#else
2999 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3000 Changing the behaviour of the former might break existing programs --
3001 where IV updating is needed, des_ncbc_encrypt can be used.
3002#endif
3003
3004 *) When bntest is run from "make test" it drives bc to check its
3005 calculations, as well as internally checking them. If an internal check
3006 fails, it needs to cause bc to give a non-zero result or make test carries
3007 on without noticing the failure. Fixed.
3008 [Ben Laurie]
3009
3010 *) DES library cleanups.
3011 [Ulf M�ller]
3012
3013 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3014 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3015 ciphers. NOTE: although the key derivation function has been verified
3016 against some published test vectors it has not been extensively tested
3017 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3018 of v2.0.
3019 [Steve Henson]
3020
3021 *) Instead of "mkdir -p", which is not fully portable, use new
3022 Perl script "util/mkdir-p.pl".
3023 [Bodo Moeller]
3024
3025 *) Rewrite the way password based encryption (PBE) is handled. It used to
3026 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3027 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3028 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3029 the 'parameter' field of the AlgorithmIdentifier is passed to the
3030 underlying key generation function so it must do its own ASN1 parsing.
3031 This has also changed the EVP_PBE_CipherInit() function which now has a
3032 'parameter' argument instead of literal salt and iteration count values
3033 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
3034 [Steve Henson]
3035
3036 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
3037 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
3038 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
3039 KEY" because this clashed with PKCS#8 unencrypted string. Since this
3040 value was just used as a "magic string" and not used directly its
3041 value doesn't matter.
3042 [Steve Henson]
3043
3044 *) Introduce some semblance of const correctness to BN. Shame C doesn't
3045 support mutable.
3046 [Ben Laurie]
3047
3048 *) "linux-sparc64" configuration (ultrapenguin).
3049 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
3050 "linux-sparc" configuration.
3051 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
3052
3053 *) config now generates no-xxx options for missing ciphers.
3054 [Ulf M�ller]
3055
3056 *) Support the EBCDIC character set (work in progress).
3057 File ebcdic.c not yet included because it has a different license.
3058 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3059
3060 *) Support BS2000/OSD-POSIX.
3061 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3062
3063 *) Make callbacks for key generation use void * instead of char *.
3064 [Ben Laurie]
3065
3066 *) Make S/MIME samples compile (not yet tested).
3067 [Ben Laurie]
3068
3069 *) Additional typesafe stacks.
3070 [Ben Laurie]
3071
3072 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
3073 [Bodo Moeller]
3074
3075
3076 Changes between 0.9.3 and 0.9.3a [29 May 1999]
3077
3078 *) New configuration variant "sco5-gcc".
3079
3080 *) Updated some demos.
3081 [Sean O Riordain, Wade Scholine]
3082
3083 *) Add missing BIO_free at exit of pkcs12 application.
3084 [Wu Zhigang]
3085
3086 *) Fix memory leak in conf.c.
3087 [Steve Henson]
3088
3089 *) Updates for Win32 to assembler version of MD5.
3090 [Steve Henson]
3091
3092 *) Set #! path to perl in apps/der_chop to where we found it
3093 instead of using a fixed path.
3094 [Bodo Moeller]
3095
3096 *) SHA library changes for irix64-mips4-cc.
3097 [Andy Polyakov]
3098
3099 *) Improvements for VMS support.
3100 [Richard Levitte]
3101
3102
3103 Changes between 0.9.2b and 0.9.3 [24 May 1999]
3104
3105 *) Bignum library bug fix. IRIX 6 passes "make test" now!
3106 This also avoids the problems with SC4.2 and unpatched SC5.
3107 [Andy Polyakov <appro@fy.chalmers.se>]
3108
3109 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
3110 These are required because of the typesafe stack would otherwise break
3111 existing code. If old code used a structure member which used to be STACK
3112 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
3113 sk_num or sk_value it would produce an error because the num, data members
3114 are not present in STACK_OF. Now it just produces a warning. sk_set
3115 replaces the old method of assigning a value to sk_value
3116 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
3117 that does this will no longer work (and should use sk_set instead) but
3118 this could be regarded as a "questionable" behaviour anyway.
3119 [Steve Henson]
3120
3121 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
3122 correctly handle encrypted S/MIME data.
3123 [Steve Henson]
3124
3125 *) Change type of various DES function arguments from des_cblock
3126 (which means, in function argument declarations, pointer to char)
3127 to des_cblock * (meaning pointer to array with 8 char elements),
3128 which allows the compiler to do more typechecking; it was like
3129 that back in SSLeay, but with lots of ugly casts.
3130
3131 Introduce new type const_des_cblock.
3132 [Bodo Moeller]
3133
3134 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
3135 problems: find RecipientInfo structure that matches recipient certificate
3136 and initialise the ASN1 structures properly based on passed cipher.
3137 [Steve Henson]
3138
3139 *) Belatedly make the BN tests actually check the results.
3140 [Ben Laurie]
3141
3142 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
3143 to and from BNs: it was completely broken. New compilation option
3144 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
3145 key elements as negative integers.
3146 [Steve Henson]
3147
3148 *) Reorganize and speed up MD5.
3149 [Andy Polyakov <appro@fy.chalmers.se>]
3150
3151 *) VMS support.
3152 [Richard Levitte <richard@levitte.org>]
3153
3154 *) New option -out to asn1parse to allow the parsed structure to be
3155 output to a file. This is most useful when combined with the -strparse
3156 option to examine the output of things like OCTET STRINGS.
3157 [Steve Henson]
3158
3159 *) Make SSL library a little more fool-proof by not requiring any longer
3160 that SSL_set_{accept,connect}_state be called before
3161 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
3162 in many applications because usually everything *appeared* to work as
3163 intended anyway -- now it really works as intended).
3164 [Bodo Moeller]
3165
3166 *) Move openssl.cnf out of lib/.
3167 [Ulf M�ller]
3168
3169 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
3170 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
3171 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
3172 [Ralf S. Engelschall]
3173
3174 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
3175 handle PKCS#7 enveloped data properly.
3176 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
3177
3178 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
3179 copying pointers. The cert_st handling is changed by this in
3180 various ways (and thus what used to be known as ctx->default_cert
3181 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
3182 any longer when s->cert does not give us what we need).
3183 ssl_cert_instantiate becomes obsolete by this change.
3184 As soon as we've got the new code right (possibly it already is?),
3185 we have solved a couple of bugs of the earlier code where s->cert
3186 was used as if it could not have been shared with other SSL structures.
3187
3188 Note that using the SSL API in certain dirty ways now will result
3189 in different behaviour than observed with earlier library versions:
3190 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
3191 does not influence s as it used to.
3192
3193 In order to clean up things more thoroughly, inside SSL_SESSION
3194 we don't use CERT any longer, but a new structure SESS_CERT
3195 that holds per-session data (if available); currently, this is
3196 the peer's certificate chain and, for clients, the server's certificate
3197 and temporary key. CERT holds only those values that can have
3198 meaningful defaults in an SSL_CTX.
3199 [Bodo Moeller]
3200
3201 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
3202 from the internal representation. Various PKCS#7 fixes: remove some
3203 evil casts and set the enc_dig_alg field properly based on the signing
3204 key type.
3205 [Steve Henson]
3206
3207 *) Allow PKCS#12 password to be set from the command line or the
3208 environment. Let 'ca' get its config file name from the environment
3209 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
3210 and 'x509').
3211 [Steve Henson]
3212
3213 *) Allow certificate policies extension to use an IA5STRING for the
3214 organization field. This is contrary to the PKIX definition but
3215 VeriSign uses it and IE5 only recognises this form. Document 'x509'
3216 extension option.
3217 [Steve Henson]
3218
3219 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
3220 without disallowing inline assembler and the like for non-pedantic builds.
3221 [Ben Laurie]
3222
3223 *) Support Borland C++ builder.
3224 [Janez Jere <jj@void.si>, modified by Ulf M�ller]
3225
3226 *) Support Mingw32.
3227 [Ulf M�ller]
3228
3229 *) SHA-1 cleanups and performance enhancements.
3230 [Andy Polyakov <appro@fy.chalmers.se>]
3231
3232 *) Sparc v8plus assembler for the bignum library.
3233 [Andy Polyakov <appro@fy.chalmers.se>]
3234
3235 *) Accept any -xxx and +xxx compiler options in Configure.
3236 [Ulf M�ller]
3237
3238 *) Update HPUX configuration.
3239 [Anonymous]
3240
3241 *) Add missing sk_<type>_unshift() function to safestack.h
3242 [Ralf S. Engelschall]
3243
3244 *) New function SSL_CTX_use_certificate_chain_file that sets the
3245 "extra_cert"s in addition to the certificate. (This makes sense
3246 only for "PEM" format files, as chains as a whole are not
3247 DER-encoded.)
3248 [Bodo Moeller]
3249
3250 *) Support verify_depth from the SSL API.
3251 x509_vfy.c had what can be considered an off-by-one-error:
3252 Its depth (which was not part of the external interface)
3253 was actually counting the number of certificates in a chain;
3254 now it really counts the depth.
3255 [Bodo Moeller]
3256
3257 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
3258 instead of X509err, which often resulted in confusing error
3259 messages since the error codes are not globally unique
3260 (e.g. an alleged error in ssl3_accept when a certificate
3261 didn't match the private key).
3262
3263 *) New function SSL_CTX_set_session_id_context that allows to set a default
3264 value (so that you don't need SSL_set_session_id_context for each
3265 connection using the SSL_CTX).
3266 [Bodo Moeller]
3267
3268 *) OAEP decoding bug fix.
3269 [Ulf M�ller]
3270
3271 *) Support INSTALL_PREFIX for package builders, as proposed by
3272 David Harris.
3273 [Bodo Moeller]
3274
3275 *) New Configure options "threads" and "no-threads". For systems
3276 where the proper compiler options are known (currently Solaris
3277 and Linux), "threads" is the default.
3278 [Bodo Moeller]
3279
3280 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
3281 [Bodo Moeller]
3282
3283 *) Install various scripts to $(OPENSSLDIR)/misc, not to
3284 $(INSTALLTOP)/bin -- they shouldn't clutter directories
3285 such as /usr/local/bin.
3286 [Bodo Moeller]
3287
3288 *) "make linux-shared" to build shared libraries.
3289 [Niels Poppe <niels@netbox.org>]
3290
3291 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
3292 [Ulf M�ller]
3293
3294 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
3295 extension adding in x509 utility.
3296 [Steve Henson]
3297
3298 *) Remove NOPROTO sections and error code comments.
3299 [Ulf M�ller]
3300
3301 *) Partial rewrite of the DEF file generator to now parse the ANSI
3302 prototypes.
3303 [Steve Henson]
3304
3305 *) New Configure options --prefix=DIR and --openssldir=DIR.
3306 [Ulf M�ller]
3307
3308 *) Complete rewrite of the error code script(s). It is all now handled
3309 by one script at the top level which handles error code gathering,
3310 header rewriting and C source file generation. It should be much better
3311 than the old method: it now uses a modified version of Ulf's parser to
3312 read the ANSI prototypes in all header files (thus the old K&R definitions
3313 aren't needed for error creation any more) and do a better job of
3314 translating function codes into names. The old 'ASN1 error code imbedded
3315 in a comment' is no longer necessary and it doesn't use .err files which
3316 have now been deleted. Also the error code call doesn't have to appear all
3317 on one line (which resulted in some large lines...).
3318 [Steve Henson]
3319
3320 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
3321 [Bodo Moeller]
3322
3323 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
3324 0 (which usually indicates a closed connection), but continue reading.
3325 [Bodo Moeller]
3326
3327 *) Fix some race conditions.
3328 [Bodo Moeller]
3329
3330 *) Add support for CRL distribution points extension. Add Certificate
3331 Policies and CRL distribution points documentation.
3332 [Steve Henson]
3333
3334 *) Move the autogenerated header file parts to crypto/opensslconf.h.
3335 [Ulf M�ller]
3336
3337 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
3338 8 of keying material. Merlin has also confirmed interop with this fix
3339 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
3340 [Merlin Hughes <merlin@baltimore.ie>]
3341
3342 *) Fix lots of warnings.
3343 [Richard Levitte <levitte@stacken.kth.se>]
3344
3345 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
3346 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
3347 [Richard Levitte <levitte@stacken.kth.se>]
3348
3349 *) Fix problems with sizeof(long) == 8.
3350 [Andy Polyakov <appro@fy.chalmers.se>]
3351
3352 *) Change functions to ANSI C.
3353 [Ulf M�ller]
3354
3355 *) Fix typos in error codes.
3356 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf M�ller]
3357
3358 *) Remove defunct assembler files from Configure.
3359 [Ulf M�ller]
3360
3361 *) SPARC v8 assembler BIGNUM implementation.
3362 [Andy Polyakov <appro@fy.chalmers.se>]
3363
3364 *) Support for Certificate Policies extension: both print and set.
3365 Various additions to support the r2i method this uses.
3366 [Steve Henson]
3367
3368 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
3369 return a const string when you are expecting an allocated buffer.
3370 [Ben Laurie]
3371
3372 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
3373 types DirectoryString and DisplayText.
3374 [Steve Henson]
3375
3376 *) Add code to allow r2i extensions to access the configuration database,
3377 add an LHASH database driver and add several ctx helper functions.
3378 [Steve Henson]
3379
3380 *) Fix an evil bug in bn_expand2() which caused various BN functions to
3381 fail when they extended the size of a BIGNUM.
3382 [Steve Henson]
3383
3384 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
3385 support typesafe stack.
3386 [Steve Henson]
3387
3388 *) Fix typo in SSL_[gs]et_options().
3389 [Nils Frostberg <nils@medcom.se>]
3390
3391 *) Delete various functions and files that belonged to the (now obsolete)
3392 old X509V3 handling code.
3393 [Steve Henson]
3394
3395 *) New Configure option "rsaref".
3396 [Ulf M�ller]
3397
3398 *) Don't auto-generate pem.h.
3399 [Bodo Moeller]
3400
3401 *) Introduce type-safe ASN.1 SETs.
3402 [Ben Laurie]
3403
3404 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
3405 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
3406
3407 *) Introduce type-safe STACKs. This will almost certainly break lots of code
3408 that links with OpenSSL (well at least cause lots of warnings), but fear
3409 not: the conversion is trivial, and it eliminates loads of evil casts. A
3410 few STACKed things have been converted already. Feel free to convert more.
3411 In the fullness of time, I'll do away with the STACK type altogether.
3412 [Ben Laurie]
3413
3414 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
3415 specified in <certfile> by updating the entry in the index.txt file.
3416 This way one no longer has to edit the index.txt file manually for
3417 revoking a certificate. The -revoke option does the gory details now.
3418 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
3419
3420 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
3421 `-text' option at all and this way the `-noout -text' combination was
3422 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
3423 [Ralf S. Engelschall]
3424
3425 *) Make sure a corresponding plain text error message exists for the
3426 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
3427 verify callback function determined that a certificate was revoked.
3428 [Ralf S. Engelschall]
3429
3430 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
3431 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
3432 all available cipers including rc5, which was forgotten until now.
3433 In order to let the testing shell script know which algorithms
3434 are available, a new (up to now undocumented) command
3435 "openssl list-cipher-commands" is used.
3436 [Bodo Moeller]
3437
3438 *) Bugfix: s_client occasionally would sleep in select() when
3439 it should have checked SSL_pending() first.
3440 [Bodo Moeller]
3441
3442 *) New functions DSA_do_sign and DSA_do_verify to provide access to
3443 the raw DSA values prior to ASN.1 encoding.
3444 [Ulf M�ller]
3445
3446 *) Tweaks to Configure
3447 [Niels Poppe <niels@netbox.org>]
3448
3449 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
3450 yet...
3451 [Steve Henson]
3452
3453 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
3454 [Ulf M�ller]
3455
3456 *) New config option to avoid instructions that are illegal on the 80386.
3457 The default code is faster, but requires at least a 486.
3458 [Ulf M�ller]
3459
3460 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
3461 SSL2_SERVER_VERSION (not used at all) macros, which are now the
3462 same as SSL2_VERSION anyway.
3463 [Bodo Moeller]
3464
3465 *) New "-showcerts" option for s_client.
3466 [Bodo Moeller]
3467
3468 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
3469 application. Various cleanups and fixes.
3470 [Steve Henson]
3471
3472 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
3473 modify error routines to work internally. Add error codes and PBE init
3474 to library startup routines.
3475 [Steve Henson]
3476
3477 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
3478 packing functions to asn1 and evp. Changed function names and error
3479 codes along the way.
3480 [Steve Henson]
3481
3482 *) PKCS12 integration: and so it begins... First of several patches to
3483 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
3484 objects to objects.h
3485 [Steve Henson]
3486
3487 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
3488 and display support for Thawte strong extranet extension.
3489 [Steve Henson]
3490
3491 *) Add LinuxPPC support.
3492 [Jeff Dubrule <igor@pobox.org>]
3493
3494 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
3495 bn_div_words in alpha.s.
3496 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
3497
3498 *) Make sure the RSA OAEP test is skipped under -DRSAref because
3499 OAEP isn't supported when OpenSSL is built with RSAref.
3500 [Ulf Moeller <ulf@fitug.de>]
3501
3502 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
3503 so they no longer are missing under -DNOPROTO.
3504 [Soren S. Jorvang <soren@t.dk>]
3505
3506
3507 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
3508
3509 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
3510 doesn't work when the session is reused. Coming soon!
3511 [Ben Laurie]
3512
3513 *) Fix a security hole, that allows sessions to be reused in the wrong
3514 context thus bypassing client cert protection! All software that uses
3515 client certs and session caches in multiple contexts NEEDS PATCHING to
3516 allow session reuse! A fuller solution is in the works.
3517 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
3518
3519 *) Some more source tree cleanups (removed obsolete files
3520 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
3521 permission on "config" script to be executable) and a fix for the INSTALL
3522 document.
3523 [Ulf Moeller <ulf@fitug.de>]
3524
3525 *) Remove some legacy and erroneous uses of malloc, free instead of
3526 Malloc, Free.
3527 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
3528
3529 *) Make rsa_oaep_test return non-zero on error.
3530 [Ulf Moeller <ulf@fitug.de>]
3531
3532 *) Add support for native Solaris shared libraries. Configure
3533 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
3534 if someone would make that last step automatic.
3535 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
3536
3537 *) ctx_size was not built with the right compiler during "make links". Fixed.
3538 [Ben Laurie]
3539
3540 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
3541 except NULL ciphers". This means the default cipher list will no longer
3542 enable NULL ciphers. They need to be specifically enabled e.g. with
3543 the string "DEFAULT:eNULL".
3544 [Steve Henson]
3545
3546 *) Fix to RSA private encryption routines: if p < q then it would
3547 occasionally produce an invalid result. This will only happen with
3548 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
3549 [Steve Henson]
3550
3551 *) Be less restrictive and allow also `perl util/perlpath.pl
3552 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
3553 because this way one can also use an interpreter named `perl5' (which is
3554 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
3555 installed as `perl').
3556 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3557
3558 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
3559 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3560
3561 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
3562 advapi32.lib to Win32 build and change the pem test comparision
3563 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
3564 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
3565 and crypto/des/ede_cbcm_enc.c.
3566 [Steve Henson]
3567
3568 *) DES quad checksum was broken on big-endian architectures. Fixed.
3569 [Ben Laurie]
3570
3571 *) Comment out two functions in bio.h that aren't implemented. Fix up the
3572 Win32 test batch file so it (might) work again. The Win32 test batch file
3573 is horrible: I feel ill....
3574 [Steve Henson]
3575
3576 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
3577 in e_os.h. Audit of header files to check ANSI and non ANSI
3578 sections: 10 functions were absent from non ANSI section and not exported
3579 from Windows DLLs. Fixed up libeay.num for new functions.
3580 [Steve Henson]
3581
3582 *) Make `openssl version' output lines consistent.
3583 [Ralf S. Engelschall]
3584
3585 *) Fix Win32 symbol export lists for BIO functions: Added
3586 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3587 to ms/libeay{16,32}.def.
3588 [Ralf S. Engelschall]
3589
3590 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3591 fine under Unix and passes some trivial tests I've now added. But the
3592 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3593 added to make sure no one expects that this stuff really works in the
3594 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3595 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3596 openssl_bio.xs.
3597 [Ralf S. Engelschall]
3598
3599 *) Fix the generation of two part addresses in perl.
3600 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3601
3602 *) Add config entry for Linux on MIPS.
3603 [John Tobey <jtobey@channel1.com>]
3604
3605 *) Make links whenever Configure is run, unless we are on Windoze.
3606 [Ben Laurie]
3607
3608 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3609 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3610 in CRLs.
3611 [Steve Henson]
3612
3613 *) Add a useful kludge to allow package maintainers to specify compiler and
3614 other platforms details on the command line without having to patch the
3615 Configure script everytime: One now can use ``perl Configure
3616 <id>:<details>'', i.e. platform ids are allowed to have details appended
3617 to them (seperated by colons). This is treated as there would be a static
3618 pre-configured entry in Configure's %table under key <id> with value
3619 <details> and ``perl Configure <id>'' is called. So, when you want to
3620 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3621 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3622 now, which overrides the FreeBSD-elf entry on-the-fly.
3623 [Ralf S. Engelschall]
3624
3625 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
3626 [Ben Laurie]
3627
3628 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
3629 on the `perl Configure ...' command line. This way one can compile
3630 OpenSSL libraries with Position Independent Code (PIC) which is needed
3631 for linking it into DSOs.
3632 [Ralf S. Engelschall]
3633
3634 *) Remarkably, export ciphers were totally broken and no-one had noticed!
3635 Fixed.
3636 [Ben Laurie]
3637
3638 *) Cleaned up the LICENSE document: The official contact for any license
3639 questions now is the OpenSSL core team under openssl-core@openssl.org.
3640 And add a paragraph about the dual-license situation to make sure people
3641 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
3642 to the OpenSSL toolkit.
3643 [Ralf S. Engelschall]
3644
3645 *) General source tree makefile cleanups: Made `making xxx in yyy...'
3646 display consistent in the source tree and replaced `/bin/rm' by `rm'.
3647 Additonally cleaned up the `make links' target: Remove unnecessary
3648 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
3649 to speed processing and no longer clutter the display with confusing
3650 stuff. Instead only the actually done links are displayed.
3651 [Ralf S. Engelschall]
3652
3653 *) Permit null encryption ciphersuites, used for authentication only. It used
3654 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
3655 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
3656 encryption.
3657 [Ben Laurie]
3658
3659 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
3660 signed attributes when verifying signatures (this would break them),
3661 the detached data encoding was wrong and public keys obtained using
3662 X509_get_pubkey() weren't freed.
3663 [Steve Henson]
3664
3665 *) Add text documentation for the BUFFER functions. Also added a work around
3666 to a Win95 console bug. This was triggered by the password read stuff: the
3667 last character typed gets carried over to the next fread(). If you were
3668 generating a new cert request using 'req' for example then the last
3669 character of the passphrase would be CR which would then enter the first
3670 field as blank.
3671 [Steve Henson]
3672
3673 *) Added the new `Includes OpenSSL Cryptography Software' button as
3674 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
3675 button and can be used by applications based on OpenSSL to show the
3676 relationship to the OpenSSL project.
3677 [Ralf S. Engelschall]
3678
3679 *) Remove confusing variables in function signatures in files
3680 ssl/ssl_lib.c and ssl/ssl.h.
3681 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3682
3683 *) Don't install bss_file.c under PREFIX/include/
3684 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3685
3686 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
3687 functions that return function pointers and has support for NT specific
3688 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
3689 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
3690 unsigned to signed types: this was killing the Win32 compile.
3691 [Steve Henson]
3692
3693 *) Add new certificate file to stack functions,
3694 SSL_add_dir_cert_subjects_to_stack() and
3695 SSL_add_file_cert_subjects_to_stack(). These largely supplant
3696 SSL_load_client_CA_file(), and can be used to add multiple certs easily
3697 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
3698 This means that Apache-SSL and similar packages don't have to mess around
3699 to add as many CAs as they want to the preferred list.
3700 [Ben Laurie]
3701
3702 *) Experiment with doxygen documentation. Currently only partially applied to
3703 ssl/ssl_lib.c.
3704 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
3705 openssl.doxy as the configuration file.
3706 [Ben Laurie]
3707
3708 *) Get rid of remaining C++-style comments which strict C compilers hate.
3709 [Ralf S. Engelschall, pointed out by Carlos Amengual]
3710
3711 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3712 compiled in by default: it has problems with large keys.
3713 [Steve Henson]
3714
3715 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3716 DH private keys and/or callback functions which directly correspond to
3717 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3718 is needed for applications which have to configure certificates on a
3719 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
3720 (e.g. s_server).
3721 For the RSA certificate situation is makes no difference, but
3722 for the DSA certificate situation this fixes the "no shared cipher"
3723 problem where the OpenSSL cipher selection procedure failed because the
3724 temporary keys were not overtaken from the context and the API provided
3725 no way to reconfigure them.
3726 The new functions now let applications reconfigure the stuff and they
3727 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
3728 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
3729 non-public-API function ssl_cert_instantiate() is used as a helper
3730 function and also to reduce code redundancy inside ssl_rsa.c.
3731 [Ralf S. Engelschall]
3732
3733 *) Move s_server -dcert and -dkey options out of the undocumented feature
3734 area because they are useful for the DSA situation and should be
3735 recognized by the users.
3736 [Ralf S. Engelschall]
3737
3738 *) Fix the cipher decision scheme for export ciphers: the export bits are
3739 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
3740 SSL_EXP_MASK. So, the original variable has to be used instead of the
3741 already masked variable.
3742 [Richard Levitte <levitte@stacken.kth.se>]
3743
3744 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
3745 [Richard Levitte <levitte@stacken.kth.se>]
3746
3747 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
3748 from `int' to `unsigned int' because it's a length and initialized by
3749 EVP_DigestFinal() which expects an `unsigned int *'.
3750 [Richard Levitte <levitte@stacken.kth.se>]
3751
3752 *) Don't hard-code path to Perl interpreter on shebang line of Configure
3753 script. Instead use the usual Shell->Perl transition trick.
3754 [Ralf S. Engelschall]
3755
3756 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
3757 (in addition to RSA certificates) to match the behaviour of `openssl dsa
3758 -noout -modulus' as it's already the case for `openssl rsa -noout
3759 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
3760 currently the public key is printed (a decision which was already done by
3761 `openssl dsa -modulus' in the past) which serves a similar purpose.
3762 Additionally the NO_RSA no longer completely removes the whole -modulus
3763 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
3764 now, too.
3765 [Ralf S. Engelschall]
3766
3767 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
3768 BIO. See the source (crypto/evp/bio_ok.c) for more info.
3769 [Arne Ansper <arne@ats.cyber.ee>]
3770
3771 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
3772 to be added. Now both 'req' and 'ca' can use new objects defined in the
3773 config file.
3774 [Steve Henson]
3775
3776 *) Add cool BIO that does syslog (or event log on NT).
3777 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
3778
3779 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
3780 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
3781 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
3782 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
3783 [Ben Laurie]
3784
3785 *) Add preliminary config info for new extension code.
3786 [Steve Henson]
3787
3788 *) Make RSA_NO_PADDING really use no padding.
3789 [Ulf Moeller <ulf@fitug.de>]
3790
3791 *) Generate errors when private/public key check is done.
3792 [Ben Laurie]
3793
3794 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
3795 for some CRL extensions and new objects added.
3796 [Steve Henson]
3797
3798 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
3799 key usage extension and fuller support for authority key id.
3800 [Steve Henson]
3801
3802 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
3803 padding method for RSA, which is recommended for new applications in PKCS
3804 #1 v2.0 (RFC 2437, October 1998).
3805 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
3806 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
3807 against Bleichbacher's attack on RSA.
3808 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
3809 Ben Laurie]
3810
3811 *) Updates to the new SSL compression code
3812 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3813
3814 *) Fix so that the version number in the master secret, when passed
3815 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
3816 (because the server will not accept higher), that the version number
3817 is 0x03,0x01, not 0x03,0x00
3818 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3819
3820 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
3821 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
3822 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
3823 [Steve Henson]
3824
3825 *) Support for RAW extensions where an arbitrary extension can be
3826 created by including its DER encoding. See apps/openssl.cnf for
3827 an example.
3828 [Steve Henson]
3829
3830 *) Make sure latest Perl versions don't interpret some generated C array
3831 code as Perl array code in the crypto/err/err_genc.pl script.
3832 [Lars Weber <3weber@informatik.uni-hamburg.de>]
3833
3834 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
3835 not many people have the assembler. Various Win32 compilation fixes and
3836 update to the INSTALL.W32 file with (hopefully) more accurate Win32
3837 build instructions.
3838 [Steve Henson]
3839
3840 *) Modify configure script 'Configure' to automatically create crypto/date.h
3841 file under Win32 and also build pem.h from pem.org. New script
3842 util/mkfiles.pl to create the MINFO file on environments that can't do a
3843 'make files': perl util/mkfiles.pl >MINFO should work.
3844 [Steve Henson]
3845
3846 *) Major rework of DES function declarations, in the pursuit of correctness
3847 and purity. As a result, many evil casts evaporated, and some weirdness,
3848 too. You may find this causes warnings in your code. Zapping your evil
3849 casts will probably fix them. Mostly.
3850 [Ben Laurie]
3851
3852 *) Fix for a typo in asn1.h. Bug fix to object creation script
3853 obj_dat.pl. It considered a zero in an object definition to mean
3854 "end of object": none of the objects in objects.h have any zeros
3855 so it wasn't spotted.
3856 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
3857
3858 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
3859 Masking (CBCM). In the absence of test vectors, the best I have been able
3860 to do is check that the decrypt undoes the encrypt, so far. Send me test
3861 vectors if you have them.
3862 [Ben Laurie]
3863
3864 *) Correct calculation of key length for export ciphers (too much space was
3865 allocated for null ciphers). This has not been tested!
3866 [Ben Laurie]
3867
3868 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
3869 message is now correct (it understands "crypto" and "ssl" on its
3870 command line). There is also now an "update" option. This will update
3871 the util/ssleay.num and util/libeay.num files with any new functions.
3872 If you do a:
3873 perl util/mkdef.pl crypto ssl update
3874 it will update them.
3875 [Steve Henson]
3876
3877 *) Overhauled the Perl interface (perl/*):
3878 - ported BN stuff to OpenSSL's different BN library
3879 - made the perl/ source tree CVS-aware
3880 - renamed the package from SSLeay to OpenSSL (the files still contain
3881 their history because I've copied them in the repository)
3882 - removed obsolete files (the test scripts will be replaced
3883 by better Test::Harness variants in the future)
3884 [Ralf S. Engelschall]
3885
3886 *) First cut for a very conservative source tree cleanup:
3887 1. merge various obsolete readme texts into doc/ssleay.txt
3888 where we collect the old documents and readme texts.
3889 2. remove the first part of files where I'm already sure that we no
3890 longer need them because of three reasons: either they are just temporary
3891 files which were left by Eric or they are preserved original files where
3892 I've verified that the diff is also available in the CVS via "cvs diff
3893 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
3894 the crypto/md/ stuff).
3895 [Ralf S. Engelschall]
3896
3897 *) More extension code. Incomplete support for subject and issuer alt
3898 name, issuer and authority key id. Change the i2v function parameters
3899 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
3900 what that's for :-) Fix to ASN1 macro which messed up
3901 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
3902 [Steve Henson]
3903
3904 *) Preliminary support for ENUMERATED type. This is largely copied from the
3905 INTEGER code.
3906 [Steve Henson]
3907
3908 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
3909 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3910
3911 *) Make sure `make rehash' target really finds the `openssl' program.
3912 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3913
3914 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3915 like to hear about it if this slows down other processors.
3916 [Ben Laurie]
3917
3918 *) Add CygWin32 platform information to Configure script.
3919 [Alan Batie <batie@aahz.jf.intel.com>]
3920
3921 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3922 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3923
3924 *) New program nseq to manipulate netscape certificate sequences
3925 [Steve Henson]
3926
3927 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3928 few typos.
3929 [Steve Henson]
3930
3931 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3932 but the BN code had some problems that would cause failures when
3933 doing certificate verification and some other functions.
3934 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3935
3936 *) Add ASN1 and PEM code to support netscape certificate sequences.
3937 [Steve Henson]
3938
3939 *) Add ASN1 and PEM code to support netscape certificate sequences.
3940 [Steve Henson]
3941
3942 *) Add several PKIX and private extended key usage OIDs.
3943 [Steve Henson]
3944
3945 *) Modify the 'ca' program to handle the new extension code. Modify
3946 openssl.cnf for new extension format, add comments.
3947 [Steve Henson]
3948
3949 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3950 and add a sample to openssl.cnf so req -x509 now adds appropriate
3951 CA extensions.
3952 [Steve Henson]
3953
3954 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3955 error code, add initial support to X509_print() and x509 application.
3956 [Steve Henson]
3957
3958 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3959 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3960 stuff is currently isolated and isn't even compiled yet.
3961 [Steve Henson]
3962
3963 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3964 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3965 Removed the versions check from X509 routines when loading extensions:
3966 this allows certain broken certificates that don't set the version
3967 properly to be processed.
3968 [Steve Henson]
3969
3970 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3971 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3972 can still be regenerated with "make depend".
3973 [Ben Laurie]
3974
3975 *) Spelling mistake in C version of CAST-128.
3976 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3977
3978 *) Changes to the error generation code. The perl script err-code.pl
3979 now reads in the old error codes and retains the old numbers, only
3980 adding new ones if necessary. It also only changes the .err files if new
3981 codes are added. The makefiles have been modified to only insert errors
3982 when needed (to avoid needlessly modifying header files). This is done
3983 by only inserting errors if the .err file is newer than the auto generated
3984 C file. To rebuild all the error codes from scratch (the old behaviour)
3985 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3986 or delete all the .err files.
3987 [Steve Henson]
3988
3989 *) CAST-128 was incorrectly implemented for short keys. The C version has
3990 been fixed, but is untested. The assembler versions are also fixed, but
3991 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
3992 to regenerate it if needed.
3993 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
3994 Hagino <itojun@kame.net>]
3995
3996 *) File was opened incorrectly in randfile.c.
3997 [Ulf M�ller <ulf@fitug.de>]
3998
3999 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4000 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4001 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4002 al: it's just almost always a UTCTime. Note this patch adds new error
4003 codes so do a "make errors" if there are problems.
4004 [Steve Henson]
4005
4006 *) Correct Linux 1 recognition in config.
4007 [Ulf M�ller <ulf@fitug.de>]
4008
4009 *) Remove pointless MD5 hash when using DSA keys in ca.
4010 [Anonymous <nobody@replay.com>]
4011
4012 *) Generate an error if given an empty string as a cert directory. Also
4013 generate an error if handed NULL (previously returned 0 to indicate an
4014 error, but didn't set one).
4015 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4016
4017 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4018 [Ben Laurie]
4019
4020 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4021 parameters. This was causing a warning which killed off the Win32 compile.
4022 [Steve Henson]
4023
4024 *) Remove C++ style comments from crypto/bn/bn_local.h.
4025 [Neil Costigan <neil.costigan@celocom.com>]
4026
4027 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4028 based on a text string, looking up short and long names and finally
4029 "dot" format. The "dot" format stuff didn't work. Added new function
4030 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4031 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
4032 OID is not part of the table.
4033 [Steve Henson]
4034
4035 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
4036 X509_LOOKUP_by_alias().
4037 [Ben Laurie]
4038
4039 *) Sort openssl functions by name.
4040 [Ben Laurie]
4041
4042 *) Get the gendsa program working (hopefully) and add it to app list. Remove
4043 encryption from sample DSA keys (in case anyone is interested the password
4044 was "1234").
4045 [Steve Henson]
4046
4047 *) Make _all_ *_free functions accept a NULL pointer.
4048 [Frans Heymans <fheymans@isaserver.be>]
4049
4050 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
4051 NULL pointers.
4052 [Anonymous <nobody@replay.com>]
4053
4054 *) s_server should send the CAfile as acceptable CAs, not its own cert.
4055 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4056
4057 *) Don't blow it for numeric -newkey arguments to apps/req.
4058 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4059
4060 *) Temp key "for export" tests were wrong in s3_srvr.c.
4061 [Anonymous <nobody@replay.com>]
4062
4063 *) Add prototype for temp key callback functions
4064 SSL_CTX_set_tmp_{rsa,dh}_callback().
4065 [Ben Laurie]
4066
4067 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
4068 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
4069 [Steve Henson]
4070
4071 *) X509_name_add_entry() freed the wrong thing after an error.
4072 [Arne Ansper <arne@ats.cyber.ee>]
4073
4074 *) rsa_eay.c would attempt to free a NULL context.
4075 [Arne Ansper <arne@ats.cyber.ee>]
4076
4077 *) BIO_s_socket() had a broken should_retry() on Windoze.
4078 [Arne Ansper <arne@ats.cyber.ee>]
4079
4080 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
4081 [Arne Ansper <arne@ats.cyber.ee>]
4082
4083 *) Make sure the already existing X509_STORE->depth variable is initialized
4084 in X509_STORE_new(), but document the fact that this variable is still
4085 unused in the certificate verification process.
4086 [Ralf S. Engelschall]
4087
4088 *) Fix the various library and apps files to free up pkeys obtained from
4089 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
4090 [Steve Henson]
4091
4092 *) Fix reference counting in X509_PUBKEY_get(). This makes
4093 demos/maurice/example2.c work, amongst others, probably.
4094 [Steve Henson and Ben Laurie]
4095
4096 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
4097 `openssl' and second, the shortcut symlinks for the `openssl <command>'
4098 are no longer created. This way we have a single and consistent command
4099 line interface `openssl <command>', similar to `cvs <command>'.
4100 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
4101
4102 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
4103 BIT STRING wrapper always have zero unused bits.
4104 [Steve Henson]
4105
4106 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
4107 [Steve Henson]
4108
4109 *) Make the top-level INSTALL documentation easier to understand.
4110 [Paul Sutton]
4111
4112 *) Makefiles updated to exit if an error occurs in a sub-directory
4113 make (including if user presses ^C) [Paul Sutton]
4114
4115 *) Make Montgomery context stuff explicit in RSA data structure.
4116 [Ben Laurie]
4117
4118 *) Fix build order of pem and err to allow for generated pem.h.
4119 [Ben Laurie]
4120
4121 *) Fix renumbering bug in X509_NAME_delete_entry().
4122 [Ben Laurie]
4123
4124 *) Enhanced the err-ins.pl script so it makes the error library number
4125 global and can add a library name. This is needed for external ASN1 and
4126 other error libraries.
4127 [Steve Henson]
4128
4129 *) Fixed sk_insert which never worked properly.
4130 [Steve Henson]
4131
4132 *) Fix ASN1 macros so they can handle indefinite length construted
4133 EXPLICIT tags. Some non standard certificates use these: they can now
4134 be read in.
4135 [Steve Henson]
4136
4137 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
4138 into a single doc/ssleay.txt bundle. This way the information is still
4139 preserved but no longer messes up this directory. Now it's new room for
4140 the new set of documenation files.
4141 [Ralf S. Engelschall]
4142
4143 *) SETs were incorrectly DER encoded. This was a major pain, because they
4144 shared code with SEQUENCEs, which aren't coded the same. This means that
4145 almost everything to do with SETs or SEQUENCEs has either changed name or
4146 number of arguments.
4147 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
4148
4149 *) Fix test data to work with the above.
4150 [Ben Laurie]
4151
4152 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
4153 was already fixed by Eric for 0.9.1 it seems.
4154 [Ben Laurie - pointed out by Ulf M�ller <ulf@fitug.de>]
4155
4156 *) Autodetect FreeBSD3.
4157 [Ben Laurie]
4158
4159 *) Fix various bugs in Configure. This affects the following platforms:
4160 nextstep
4161 ncr-scde
4162 unixware-2.0
4163 unixware-2.0-pentium
4164 sco5-cc.
4165 [Ben Laurie]
4166
4167 *) Eliminate generated files from CVS. Reorder tests to regenerate files
4168 before they are needed.
4169 [Ben Laurie]
4170
4171 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
4172 [Ben Laurie]
4173
4174
4175 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
4176
4177 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
4178 changed SSLeay to OpenSSL in version strings.
4179 [Ralf S. Engelschall]
4180
4181 *) Some fixups to the top-level documents.
4182 [Paul Sutton]
4183
4184 *) Fixed the nasty bug where rsaref.h was not found under compile-time
4185 because the symlink to include/ was missing.
4186 [Ralf S. Engelschall]
4187
4188 *) Incorporated the popular no-RSA/DSA-only patches
4189 which allow to compile a RSA-free SSLeay.
4190 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
4191
4192 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
4193 when "ssleay" is still not found.
4194 [Ralf S. Engelschall]
4195
4196 *) Added more platforms to Configure: Cray T3E, HPUX 11,
4197 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
4198
4199 *) Updated the README file.
4200 [Ralf S. Engelschall]
4201
4202 *) Added various .cvsignore files in the CVS repository subdirs
4203 to make a "cvs update" really silent.
4204 [Ralf S. Engelschall]
4205
4206 *) Recompiled the error-definition header files and added
4207 missing symbols to the Win32 linker tables.
4208 [Ralf S. Engelschall]
4209
4210 *) Cleaned up the top-level documents;
4211 o new files: CHANGES and LICENSE
4212 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
4213 o merged COPYRIGHT into LICENSE
4214 o removed obsolete TODO file
4215 o renamed MICROSOFT to INSTALL.W32
4216 [Ralf S. Engelschall]
4217
4218 *) Removed dummy files from the 0.9.1b source tree:
4219 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
4220 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
4221 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
4222 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
4223 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
4224 [Ralf S. Engelschall]
4225
4226 *) Added various platform portability fixes.
4227 [Mark J. Cox]
4228
4229 *) The Genesis of the OpenSSL rpject:
4230 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
4231 Young and Tim J. Hudson created while they were working for C2Net until
4232 summer 1998.
4233 [The OpenSSL Project]
4234
4235
4236 Changes between 0.9.0b and 0.9.1b [not released]
4237
4238 *) Updated a few CA certificates under certs/
4239 [Eric A. Young]
4240
4241 *) Changed some BIGNUM api stuff.
4242 [Eric A. Young]
4243
4244 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
4245 DGUX x86, Linux Alpha, etc.
4246 [Eric A. Young]
4247
4248 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
4249 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
4250 available).
4251 [Eric A. Young]
4252
4253 *) Add -strparse option to asn1pars program which parses nested
4254 binary structures
4255 [Dr Stephen Henson <shenson@bigfoot.com>]
4256
4257 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
4258 [Eric A. Young]
4259
4260 *) DSA fix for "ca" program.
4261 [Eric A. Young]
4262
4263 *) Added "-genkey" option to "dsaparam" program.
4264 [Eric A. Young]
4265
4266 *) Added RIPE MD160 (rmd160) message digest.
4267 [Eric A. Young]
4268
4269 *) Added -a (all) option to "ssleay version" command.
4270 [Eric A. Young]
4271
4272 *) Added PLATFORM define which is the id given to Configure.
4273 [Eric A. Young]
4274
4275 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
4276 [Eric A. Young]
4277
4278 *) Extended the ASN.1 parser routines.
4279 [Eric A. Young]
4280
4281 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
4282 [Eric A. Young]
4283
4284 *) Added a BN_CTX to the BN library.
4285 [Eric A. Young]
4286
4287 *) Fixed the weak key values in DES library
4288 [Eric A. Young]
4289
4290 *) Changed API in EVP library for cipher aliases.
4291 [Eric A. Young]
4292
4293 *) Added support for RC2/64bit cipher.
4294 [Eric A. Young]
4295
4296 *) Converted the lhash library to the crypto/mem.c functions.
4297 [Eric A. Young]
4298
4299 *) Added more recognized ASN.1 object ids.
4300 [Eric A. Young]
4301
4302 *) Added more RSA padding checks for SSL/TLS.
4303 [Eric A. Young]
4304
4305 *) Added BIO proxy/filter functionality.
4306 [Eric A. Young]
4307
4308 *) Added extra_certs to SSL_CTX which can be used
4309 send extra CA certificates to the client in the CA cert chain sending
4310 process. It can be configured with SSL_CTX_add_extra_chain_cert().
4311 [Eric A. Young]
4312
4313 *) Now Fortezza is denied in the authentication phase because
4314 this is key exchange mechanism is not supported by SSLeay at all.
4315 [Eric A. Young]
4316
4317 *) Additional PKCS1 checks.
4318 [Eric A. Young]
4319
4320 *) Support the string "TLSv1" for all TLS v1 ciphers.
4321 [Eric A. Young]
4322
4323 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
4324 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
4325 [Eric A. Young]
4326
4327 *) Fixed a few memory leaks.
4328 [Eric A. Young]
4329
4330 *) Fixed various code and comment typos.
4331 [Eric A. Young]
4332
4333 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
4334 bytes sent in the client random.
4335 [Edward Bishop <ebishop@spyglass.com>]
4336
| 18 Changes between 0.9.6d and 0.9.6e [30 Jul 2002]
19
20 *) Fix cipher selection routines: ciphers without encryption had no flags
21 for the cipher strength set and where therefore not handled correctly
22 by the selection routines (PR #130).
23 [Lutz Jaenicke]
24
25 *) Fix EVP_dsa_sha macro.
26 [Nils Larsch]
27
28 *) New option
29 SSL_OP_DONT_INSERT_EMPTY_FRAGMENTS
30 for disabling the SSL 3.0/TLS 1.0 CBC vulnerability countermeasure
31 that was added in OpenSSL 0.9.6d.
32
33 As the countermeasure turned out to be incompatible with some
34 broken SSL implementations, the new option is part of SSL_OP_ALL.
35 SSL_OP_ALL is usually employed when compatibility with weird SSL
36 implementations is desired (e.g. '-bugs' option to 's_client' and
37 's_server'), so the new option is automatically set in many
38 applications.
39 [Bodo Moeller]
40
41 *) Changes in security patch:
42
43 Changes marked "(CHATS)" were sponsored by the Defense Advanced
44 Research Projects Agency (DARPA) and Air Force Research Laboratory,
45 Air Force Materiel Command, USAF, under agreement number
46 F30602-01-2-0537.
47
48 *) Add various sanity checks to asn1_get_length() to reject
49 the ASN1 length bytes if they exceed sizeof(long), will appear
50 negative or the content length exceeds the length of the
51 supplied buffer.
52 [Steve Henson, Adi Stav <stav@mercury.co.il>, James Yonan <jim@ntlp.com>]
53
54 *) Assertions for various potential buffer overflows, not known to
55 happen in practice.
56 [Ben Laurie (CHATS)]
57
58 *) Various temporary buffers to hold ASCII versions of integers were
59 too small for 64 bit platforms. (CAN-2002-0655)
60 [Matthew Byng-Maddick <mbm@aldigital.co.uk> and Ben Laurie (CHATS)>
61
62 *) Remote buffer overflow in SSL3 protocol - an attacker could
63 supply an oversized session ID to a client. (CAN-2002-0656)
64 [Ben Laurie (CHATS)]
65
66 *) Remote buffer overflow in SSL2 protocol - an attacker could
67 supply an oversized client master key. (CAN-2002-0656)
68 [Ben Laurie (CHATS)]
69
70 Changes between 0.9.6c and 0.9.6d [9 May 2002]
71
72 *) Fix crypto/asn1/a_sign.c so that 'parameters' is omitted (not
73 encoded as NULL) with id-dsa-with-sha1.
74 [Nils Larsch <nla@trustcenter.de>; problem pointed out by Bodo Moeller]
75
76 *) Check various X509_...() return values in apps/req.c.
77 [Nils Larsch <nla@trustcenter.de>]
78
79 *) Fix BASE64 decode (EVP_DecodeUpdate) for data with CR/LF ended lines:
80 an end-of-file condition would erronously be flagged, when the CRLF
81 was just at the end of a processed block. The bug was discovered when
82 processing data through a buffering memory BIO handing the data to a
83 BASE64-decoding BIO. Bug fund and patch submitted by Pavel Tsekov
84 <ptsekov@syntrex.com> and Nedelcho Stanev.
85 [Lutz Jaenicke]
86
87 *) Implement a countermeasure against a vulnerability recently found
88 in CBC ciphersuites in SSL 3.0/TLS 1.0: Send an empty fragment
89 before application data chunks to avoid the use of known IVs
90 with data potentially chosen by the attacker.
91 [Bodo Moeller]
92
93 *) Fix length checks in ssl3_get_client_hello().
94 [Bodo Moeller]
95
96 *) TLS/SSL library bugfix: use s->s3->in_read_app_data differently
97 to prevent ssl3_read_internal() from incorrectly assuming that
98 ssl3_read_bytes() found application data while handshake
99 processing was enabled when in fact s->s3->in_read_app_data was
100 merely automatically cleared during the initial handshake.
101 [Bodo Moeller; problem pointed out by Arne Ansper <arne@ats.cyber.ee>]
102
103 *) Fix object definitions for Private and Enterprise: they were not
104 recognized in their shortname (=lowercase) representation. Extend
105 obj_dat.pl to issue an error when using undefined keywords instead
106 of silently ignoring the problem (Svenning Sorensen
107 <sss@sss.dnsalias.net>).
108 [Lutz Jaenicke]
109
110 *) Fix DH_generate_parameters() so that it works for 'non-standard'
111 generators, i.e. generators other than 2 and 5. (Previously, the
112 code did not properly initialise the 'add' and 'rem' values to
113 BN_generate_prime().)
114
115 In the new general case, we do not insist that 'generator' is
116 actually a primitive root: This requirement is rather pointless;
117 a generator of the order-q subgroup is just as good, if not
118 better.
119 [Bodo Moeller]
120
121 *) Map new X509 verification errors to alerts. Discovered and submitted by
122 Tom Wu <tom@arcot.com>.
123 [Lutz Jaenicke]
124
125 *) Fix ssl3_pending() (ssl/s3_lib.c) to prevent SSL_pending() from
126 returning non-zero before the data has been completely received
127 when using non-blocking I/O.
128 [Bodo Moeller; problem pointed out by John Hughes]
129
130 *) Some of the ciphers missed the strength entry (SSL_LOW etc).
131 [Ben Laurie, Lutz Jaenicke]
132
133 *) Fix bug in SSL_clear(): bad sessions were not removed (found by
134 Yoram Zahavi <YoramZ@gilian.com>).
135 [Lutz Jaenicke]
136
137 *) Add information about CygWin 1.3 and on, and preserve proper
138 configuration for the versions before that.
139 [Corinna Vinschen <vinschen@redhat.com> and Richard Levitte]
140
141 *) Make removal from session cache (SSL_CTX_remove_session()) more robust:
142 check whether we deal with a copy of a session and do not delete from
143 the cache in this case. Problem reported by "Izhar Shoshani Levi"
144 <izhar@checkpoint.com>.
145 [Lutz Jaenicke]
146
147 *) Do not store session data into the internal session cache, if it
148 is never intended to be looked up (SSL_SESS_CACHE_NO_INTERNAL_LOOKUP
149 flag is set). Proposed by Aslam <aslam@funk.com>.
150 [Lutz Jaenicke]
151
152 *) Have ASN1_BIT_STRING_set_bit() really clear a bit when the requested
153 value is 0.
154 [Richard Levitte]
155
156 *) [In 0.9.6c-engine release:]
157 Fix a crashbug and a logic bug in hwcrhk_load_pubkey()
158 [Toomas Kiisk <vix@cyber.ee> via Richard Levitte]
159
160 *) Add the configuration target linux-s390x.
161 [Neale Ferguson <Neale.Ferguson@SoftwareAG-USA.com> via Richard Levitte]
162
163 *) The earlier bugfix for the SSL3_ST_SW_HELLO_REQ_C case of
164 ssl3_accept (ssl/s3_srvr.c) incorrectly used a local flag
165 variable as an indication that a ClientHello message has been
166 received. As the flag value will be lost between multiple
167 invocations of ssl3_accept when using non-blocking I/O, the
168 function may not be aware that a handshake has actually taken
169 place, thus preventing a new session from being added to the
170 session cache.
171
172 To avoid this problem, we now set s->new_session to 2 instead of
173 using a local variable.
174 [Lutz Jaenicke, Bodo Moeller]
175
176 *) Bugfix: Return -1 from ssl3_get_server_done (ssl3/s3_clnt.c)
177 if the SSL_R_LENGTH_MISMATCH error is detected.
178 [Geoff Thorpe, Bodo Moeller]
179
180 *) New 'shared_ldflag' column in Configure platform table.
181 [Richard Levitte]
182
183 *) Fix EVP_CIPHER_mode macro.
184 ["Dan S. Camper" <dan@bti.net>]
185
186 *) Fix ssl3_read_bytes (ssl/s3_pkt.c): To ignore messages of unknown
187 type, we must throw them away by setting rr->length to 0.
188 [D P Chang <dpc@qualys.com>]
189
190 Changes between 0.9.6b and 0.9.6c [21 dec 2001]
191
192 *) Fix BN_rand_range bug pointed out by Dominikus Scherkl
193 <Dominikus.Scherkl@biodata.com>. (The previous implementation
194 worked incorrectly for those cases where range = 10..._2 and
195 3*range is two bits longer than range.)
196 [Bodo Moeller]
197
198 *) Only add signing time to PKCS7 structures if it is not already
199 present.
200 [Steve Henson]
201
202 *) Fix crypto/objects/objects.h: "ld-ce" should be "id-ce",
203 OBJ_ld_ce should be OBJ_id_ce.
204 Also some ip-pda OIDs in crypto/objects/objects.txt were
205 incorrect (cf. RFC 3039).
206 [Matt Cooper, Frederic Giudicelli, Bodo Moeller]
207
208 *) Release CRYPTO_LOCK_DYNLOCK when CRYPTO_destroy_dynlockid()
209 returns early because it has nothing to do.
210 [Andy Schneider <andy.schneider@bjss.co.uk>]
211
212 *) [In 0.9.6c-engine release:]
213 Fix mutex callback return values in crypto/engine/hw_ncipher.c.
214 [Andy Schneider <andy.schneider@bjss.co.uk>]
215
216 *) [In 0.9.6c-engine release:]
217 Add support for Cryptographic Appliance's keyserver technology.
218 (Use engine 'keyclient')
219 [Cryptographic Appliances and Geoff Thorpe]
220
221 *) Add a configuration entry for OS/390 Unix. The C compiler 'c89'
222 is called via tools/c89.sh because arguments have to be
223 rearranged (all '-L' options must appear before the first object
224 modules).
225 [Richard Shapiro <rshapiro@abinitio.com>]
226
227 *) [In 0.9.6c-engine release:]
228 Add support for Broadcom crypto accelerator cards, backported
229 from 0.9.7.
230 [Broadcom, Nalin Dahyabhai <nalin@redhat.com>, Mark Cox]
231
232 *) [In 0.9.6c-engine release:]
233 Add support for SureWare crypto accelerator cards from
234 Baltimore Technologies. (Use engine 'sureware')
235 [Baltimore Technologies and Mark Cox]
236
237 *) [In 0.9.6c-engine release:]
238 Add support for crypto accelerator cards from Accelerated
239 Encryption Processing, www.aep.ie. (Use engine 'aep')
240 [AEP Inc. and Mark Cox]
241
242 *) Add a configuration entry for gcc on UnixWare.
243 [Gary Benson <gbenson@redhat.com>]
244
245 *) Change ssl/s2_clnt.c and ssl/s2_srvr.c so that received handshake
246 messages are stored in a single piece (fixed-length part and
247 variable-length part combined) and fix various bugs found on the way.
248 [Bodo Moeller]
249
250 *) Disable caching in BIO_gethostbyname(), directly use gethostbyname()
251 instead. BIO_gethostbyname() does not know what timeouts are
252 appropriate, so entries would stay in cache even when they have
253 become invalid.
254 [Bodo Moeller; problem pointed out by Rich Salz <rsalz@zolera.com>
255
256 *) Change ssl23_get_client_hello (ssl/s23_srvr.c) behaviour when
257 faced with a pathologically small ClientHello fragment that does
258 not contain client_version: Instead of aborting with an error,
259 simply choose the highest available protocol version (i.e.,
260 TLS 1.0 unless it is disabled). In practice, ClientHello
261 messages are never sent like this, but this change gives us
262 strictly correct behaviour at least for TLS.
263 [Bodo Moeller]
264
265 *) Fix SSL handshake functions and SSL_clear() such that SSL_clear()
266 never resets s->method to s->ctx->method when called from within
267 one of the SSL handshake functions.
268 [Bodo Moeller; problem pointed out by Niko Baric]
269
270 *) In ssl3_get_client_hello (ssl/s3_srvr.c), generate a fatal alert
271 (sent using the client's version number) if client_version is
272 smaller than the protocol version in use. Also change
273 ssl23_get_client_hello (ssl/s23_srvr.c) to select TLS 1.0 if
274 the client demanded SSL 3.0 but only TLS 1.0 is enabled; then
275 the client will at least see that alert.
276 [Bodo Moeller]
277
278 *) Fix ssl3_get_message (ssl/s3_both.c) to handle message fragmentation
279 correctly.
280 [Bodo Moeller]
281
282 *) Avoid infinite loop in ssl3_get_message (ssl/s3_both.c) if a
283 client receives HelloRequest while in a handshake.
284 [Bodo Moeller; bug noticed by Andy Schneider <andy.schneider@bjss.co.uk>]
285
286 *) Bugfix in ssl3_accept (ssl/s3_srvr.c): Case SSL3_ST_SW_HELLO_REQ_C
287 should end in 'break', not 'goto end' which circuments various
288 cleanups done in state SSL_ST_OK. But session related stuff
289 must be disabled for SSL_ST_OK in the case that we just sent a
290 HelloRequest.
291
292 Also avoid some overhead by not calling ssl_init_wbio_buffer()
293 before just sending a HelloRequest.
294 [Bodo Moeller, Eric Rescorla <ekr@rtfm.com>]
295
296 *) Fix ssl/s3_enc.c, ssl/t1_enc.c and ssl/s3_pkt.c so that we don't
297 reveal whether illegal block cipher padding was found or a MAC
298 verification error occured. (Neither SSLerr() codes nor alerts
299 are directly visible to potential attackers, but the information
300 may leak via logfiles.)
301
302 Similar changes are not required for the SSL 2.0 implementation
303 because the number of padding bytes is sent in clear for SSL 2.0,
304 and the extra bytes are just ignored. However ssl/s2_pkt.c
305 failed to verify that the purported number of padding bytes is in
306 the legal range.
307 [Bodo Moeller]
308
309 *) Add OpenUNIX-8 support including shared libraries
310 (Boyd Lynn Gerber <gerberb@zenez.com>).
311 [Lutz Jaenicke]
312
313 *) Improve RSA_padding_check_PKCS1_OAEP() check again to avoid
314 'wristwatch attack' using huge encoding parameters (cf.
315 James H. Manger's CRYPTO 2001 paper). Note that the
316 RSA_PKCS1_OAEP_PADDING case of RSA_private_decrypt() does not use
317 encoding parameters and hence was not vulnerable.
318 [Bodo Moeller]
319
320 *) BN_sqr() bug fix.
321 [Ulf M�ller, reported by Jim Ellis <jim.ellis@cavium.com>]
322
323 *) Rabin-Miller test analyses assume uniformly distributed witnesses,
324 so use BN_pseudo_rand_range() instead of using BN_pseudo_rand()
325 followed by modular reduction.
326 [Bodo Moeller; pointed out by Adam Young <AYoung1@NCSUS.JNJ.COM>]
327
328 *) Add BN_pseudo_rand_range() with obvious functionality: BN_rand_range()
329 equivalent based on BN_pseudo_rand() instead of BN_rand().
330 [Bodo Moeller]
331
332 *) s3_srvr.c: allow sending of large client certificate lists (> 16 kB).
333 This function was broken, as the check for a new client hello message
334 to handle SGC did not allow these large messages.
335 (Tracked down by "Douglas E. Engert" <deengert@anl.gov>.)
336 [Lutz Jaenicke]
337
338 *) Add alert descriptions for TLSv1 to SSL_alert_desc_string[_long]().
339 [Lutz Jaenicke]
340
341 *) Fix buggy behaviour of BIO_get_num_renegotiates() and BIO_ctrl()
342 for BIO_C_GET_WRITE_BUF_SIZE ("Stephen Hinton" <shinton@netopia.com>).
343 [Lutz Jaenicke]
344
345 *) Rework the configuration and shared library support for Tru64 Unix.
346 The configuration part makes use of modern compiler features and
347 still retains old compiler behavior for those that run older versions
348 of the OS. The shared library support part includes a variant that
349 uses the RPATH feature, and is available through the special
350 configuration target "alpha-cc-rpath", which will never be selected
351 automatically.
352 [Tim Mooney <mooney@dogbert.cc.ndsu.NoDak.edu> via Richard Levitte]
353
354 *) In ssl3_get_key_exchange (ssl/s3_clnt.c), call ssl3_get_message()
355 with the same message size as in ssl3_get_certificate_request().
356 Otherwise, if no ServerKeyExchange message occurs, CertificateRequest
357 messages might inadvertently be reject as too long.
358 [Petr Lampa <lampa@fee.vutbr.cz>]
359
360 *) Enhanced support for IA-64 Unix platforms (well, Linux and HP-UX).
361 [Andy Polyakov]
362
363 *) Modified SSL library such that the verify_callback that has been set
364 specificly for an SSL object with SSL_set_verify() is actually being
365 used. Before the change, a verify_callback set with this function was
366 ignored and the verify_callback() set in the SSL_CTX at the time of
367 the call was used. New function X509_STORE_CTX_set_verify_cb() introduced
368 to allow the necessary settings.
369 [Lutz Jaenicke]
370
371 *) Initialize static variable in crypto/dsa/dsa_lib.c and crypto/dh/dh_lib.c
372 explicitly to NULL, as at least on Solaris 8 this seems not always to be
373 done automatically (in contradiction to the requirements of the C
374 standard). This made problems when used from OpenSSH.
375 [Lutz Jaenicke]
376
377 *) In OpenSSL 0.9.6a and 0.9.6b, crypto/dh/dh_key.c ignored
378 dh->length and always used
379
380 BN_rand_range(priv_key, dh->p).
381
382 BN_rand_range() is not necessary for Diffie-Hellman, and this
383 specific range makes Diffie-Hellman unnecessarily inefficient if
384 dh->length (recommended exponent length) is much smaller than the
385 length of dh->p. We could use BN_rand_range() if the order of
386 the subgroup was stored in the DH structure, but we only have
387 dh->length.
388
389 So switch back to
390
391 BN_rand(priv_key, l, ...)
392
393 where 'l' is dh->length if this is defined, or BN_num_bits(dh->p)-1
394 otherwise.
395 [Bodo Moeller]
396
397 *) In
398
399 RSA_eay_public_encrypt
400 RSA_eay_private_decrypt
401 RSA_eay_private_encrypt (signing)
402 RSA_eay_public_decrypt (signature verification)
403
404 (default implementations for RSA_public_encrypt,
405 RSA_private_decrypt, RSA_private_encrypt, RSA_public_decrypt),
406 always reject numbers >= n.
407 [Bodo Moeller]
408
409 *) In crypto/rand/md_rand.c, use a new short-time lock CRYPTO_LOCK_RAND2
410 to synchronize access to 'locking_thread'. This is necessary on
411 systems where access to 'locking_thread' (an 'unsigned long'
412 variable) is not atomic.
413 [Bodo Moeller]
414
415 *) In crypto/rand/md_rand.c, set 'locking_thread' to current thread's ID
416 *before* setting the 'crypto_lock_rand' flag. The previous code had
417 a race condition if 0 is a valid thread ID.
418 [Travis Vitek <vitek@roguewave.com>]
419
420 *) Add support for shared libraries under Irix.
421 [Albert Chin-A-Young <china@thewrittenword.com>]
422
423 *) Add configuration option to build on Linux on both big-endian and
424 little-endian MIPS.
425 [Ralf Baechle <ralf@uni-koblenz.de>]
426
427 *) Add the possibility to create shared libraries on HP-UX.
428 [Richard Levitte]
429
430 Changes between 0.9.6a and 0.9.6b [9 Jul 2001]
431
432 *) Change ssleay_rand_bytes (crypto/rand/md_rand.c)
433 to avoid a SSLeay/OpenSSL PRNG weakness pointed out by
434 Markku-Juhani O. Saarinen <markku-juhani.saarinen@nokia.com>:
435 PRNG state recovery was possible based on the output of
436 one PRNG request appropriately sized to gain knowledge on
437 'md' followed by enough consecutive 1-byte PRNG requests
438 to traverse all of 'state'.
439
440 1. When updating 'md_local' (the current thread's copy of 'md')
441 during PRNG output generation, hash all of the previous
442 'md_local' value, not just the half used for PRNG output.
443
444 2. Make the number of bytes from 'state' included into the hash
445 independent from the number of PRNG bytes requested.
446
447 The first measure alone would be sufficient to avoid
448 Markku-Juhani's attack. (Actually it had never occurred
449 to me that the half of 'md_local' used for chaining was the
450 half from which PRNG output bytes were taken -- I had always
451 assumed that the secret half would be used.) The second
452 measure makes sure that additional data from 'state' is never
453 mixed into 'md_local' in small portions; this heuristically
454 further strengthens the PRNG.
455 [Bodo Moeller]
456
457 *) Fix crypto/bn/asm/mips3.s.
458 [Andy Polyakov]
459
460 *) When only the key is given to "enc", the IV is undefined. Print out
461 an error message in this case.
462 [Lutz Jaenicke]
463
464 *) Handle special case when X509_NAME is empty in X509 printing routines.
465 [Steve Henson]
466
467 *) In dsa_do_verify (crypto/dsa/dsa_ossl.c), verify that r and s are
468 positive and less than q.
469 [Bodo Moeller]
470
471 *) Don't change *pointer in CRYPTO_add_lock() is add_lock_callback is
472 used: it isn't thread safe and the add_lock_callback should handle
473 that itself.
474 [Paul Rose <Paul.Rose@bridge.com>]
475
476 *) Verify that incoming data obeys the block size in
477 ssl3_enc (ssl/s3_enc.c) and tls1_enc (ssl/t1_enc.c).
478 [Bodo Moeller]
479
480 *) Fix OAEP check.
481 [Ulf M�ller, Bodo M�ller]
482
483 *) The countermeasure against Bleichbacher's attack on PKCS #1 v1.5
484 RSA encryption was accidentally removed in s3_srvr.c in OpenSSL 0.9.5
485 when fixing the server behaviour for backwards-compatible 'client
486 hello' messages. (Note that the attack is impractical against
487 SSL 3.0 and TLS 1.0 anyway because length and version checking
488 means that the probability of guessing a valid ciphertext is
489 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98
490 paper.)
491
492 Before 0.9.5, the countermeasure (hide the error by generating a
493 random 'decryption result') did not work properly because
494 ERR_clear_error() was missing, meaning that SSL_get_error() would
495 detect the supposedly ignored error.
496
497 Both problems are now fixed.
498 [Bodo Moeller]
499
500 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096
501 (previously it was 1024).
502 [Bodo Moeller]
503
504 *) Fix for compatibility mode trust settings: ignore trust settings
505 unless some valid trust or reject settings are present.
506 [Steve Henson]
507
508 *) Fix for blowfish EVP: its a variable length cipher.
509 [Steve Henson]
510
511 *) Fix various bugs related to DSA S/MIME verification. Handle missing
512 parameters in DSA public key structures and return an error in the
513 DSA routines if parameters are absent.
514 [Steve Henson]
515
516 *) In versions up to 0.9.6, RAND_file_name() resorted to file ".rnd"
517 in the current directory if neither $RANDFILE nor $HOME was set.
518 RAND_file_name() in 0.9.6a returned NULL in this case. This has
519 caused some confusion to Windows users who haven't defined $HOME.
520 Thus RAND_file_name() is changed again: e_os.h can define a
521 DEFAULT_HOME, which will be used if $HOME is not set.
522 For Windows, we use "C:"; on other platforms, we still require
523 environment variables.
524
525 *) Move 'if (!initialized) RAND_poll()' into regions protected by
526 CRYPTO_LOCK_RAND. This is not strictly necessary, but avoids
527 having multiple threads call RAND_poll() concurrently.
528 [Bodo Moeller]
529
530 *) In crypto/rand/md_rand.c, replace 'add_do_not_lock' flag by a
531 combination of a flag and a thread ID variable.
532 Otherwise while one thread is in ssleay_rand_bytes (which sets the
533 flag), *other* threads can enter ssleay_add_bytes without obeying
534 the CRYPTO_LOCK_RAND lock (and may even illegally release the lock
535 that they do not hold after the first thread unsets add_do_not_lock).
536 [Bodo Moeller]
537
538 *) Change bctest again: '-x' expressions are not available in all
539 versions of 'test'.
540 [Bodo Moeller]
541
542 Changes between 0.9.6 and 0.9.6a [5 Apr 2001]
543
544 *) Fix a couple of memory leaks in PKCS7_dataDecode()
545 [Steve Henson, reported by Heyun Zheng <hzheng@atdsprint.com>]
546
547 *) Change Configure and Makefiles to provide EXE_EXT, which will contain
548 the default extension for executables, if any. Also, make the perl
549 scripts that use symlink() to test if it really exists and use "cp"
550 if it doesn't. All this made OpenSSL compilable and installable in
551 CygWin.
552 [Richard Levitte]
553
554 *) Fix for asn1_GetSequence() for indefinite length constructed data.
555 If SEQUENCE is length is indefinite just set c->slen to the total
556 amount of data available.
557 [Steve Henson, reported by shige@FreeBSD.org]
558 [This change does not apply to 0.9.7.]
559
560 *) Change bctest to avoid here-documents inside command substitution
561 (workaround for FreeBSD /bin/sh bug).
562 For compatibility with Ultrix, avoid shell functions (introduced
563 in the bctest version that searches along $PATH).
564 [Bodo Moeller]
565
566 *) Rename 'des_encrypt' to 'des_encrypt1'. This avoids the clashes
567 with des_encrypt() defined on some operating systems, like Solaris
568 and UnixWare.
569 [Richard Levitte]
570
571 *) Check the result of RSA-CRT (see D. Boneh, R. DeMillo, R. Lipton:
572 On the Importance of Eliminating Errors in Cryptographic
573 Computations, J. Cryptology 14 (2001) 2, 101-119,
574 http://theory.stanford.edu/~dabo/papers/faults.ps.gz).
575 [Ulf Moeller]
576
577 *) MIPS assembler BIGNUM division bug fix.
578 [Andy Polyakov]
579
580 *) Disabled incorrect Alpha assembler code.
581 [Richard Levitte]
582
583 *) Fix PKCS#7 decode routines so they correctly update the length
584 after reading an EOC for the EXPLICIT tag.
585 [Steve Henson]
586 [This change does not apply to 0.9.7.]
587
588 *) Fix bug in PKCS#12 key generation routines. This was triggered
589 if a 3DES key was generated with a 0 initial byte. Include
590 PKCS12_BROKEN_KEYGEN compilation option to retain the old
591 (but broken) behaviour.
592 [Steve Henson]
593
594 *) Enhance bctest to search for a working bc along $PATH and print
595 it when found.
596 [Tim Rice <tim@multitalents.net> via Richard Levitte]
597
598 *) Fix memory leaks in err.c: free err_data string if necessary;
599 don't write to the wrong index in ERR_set_error_data.
600 [Bodo Moeller]
601
602 *) Implement ssl23_peek (analogous to ssl23_read), which previously
603 did not exist.
604 [Bodo Moeller]
605
606 *) Replace rdtsc with _emit statements for VC++ version 5.
607 [Jeremy Cooper <jeremy@baymoo.org>]
608
609 *) Make it possible to reuse SSLv2 sessions.
610 [Richard Levitte]
611
612 *) In copy_email() check for >= 0 as a return value for
613 X509_NAME_get_index_by_NID() since 0 is a valid index.
614 [Steve Henson reported by Massimiliano Pala <madwolf@opensca.org>]
615
616 *) Avoid coredump with unsupported or invalid public keys by checking if
617 X509_get_pubkey() fails in PKCS7_verify(). Fix memory leak when
618 PKCS7_verify() fails with non detached data.
619 [Steve Henson]
620
621 *) Don't use getenv in library functions when run as setuid/setgid.
622 New function OPENSSL_issetugid().
623 [Ulf Moeller]
624
625 *) Avoid false positives in memory leak detection code (crypto/mem_dbg.c)
626 due to incorrect handling of multi-threading:
627
628 1. Fix timing glitch in the MemCheck_off() portion of CRYPTO_mem_ctrl().
629
630 2. Fix logical glitch in is_MemCheck_on() aka CRYPTO_is_mem_check_on().
631
632 3. Count how many times MemCheck_off() has been called so that
633 nested use can be treated correctly. This also avoids
634 inband-signalling in the previous code (which relied on the
635 assumption that thread ID 0 is impossible).
636 [Bodo Moeller]
637
638 *) Add "-rand" option also to s_client and s_server.
639 [Lutz Jaenicke]
640
641 *) Fix CPU detection on Irix 6.x.
642 [Kurt Hockenbury <khockenb@stevens-tech.edu> and
643 "Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
644
645 *) Fix X509_NAME bug which produced incorrect encoding if X509_NAME
646 was empty.
647 [Steve Henson]
648 [This change does not apply to 0.9.7.]
649
650 *) Use the cached encoding of an X509_NAME structure rather than
651 copying it. This is apparently the reason for the libsafe "errors"
652 but the code is actually correct.
653 [Steve Henson]
654
655 *) Add new function BN_rand_range(), and fix DSA_sign_setup() to prevent
656 Bleichenbacher's DSA attack.
657 Extend BN_[pseudo_]rand: As before, top=1 forces the highest two bits
658 to be set and top=0 forces the highest bit to be set; top=-1 is new
659 and leaves the highest bit random.
660 [Ulf Moeller, Bodo Moeller]
661
662 *) In the NCONF_...-based implementations for CONF_... queries
663 (crypto/conf/conf_lib.c), if the input LHASH is NULL, avoid using
664 a temporary CONF structure with the data component set to NULL
665 (which gives segmentation faults in lh_retrieve).
666 Instead, use NULL for the CONF pointer in CONF_get_string and
667 CONF_get_number (which may use environment variables) and directly
668 return NULL from CONF_get_section.
669 [Bodo Moeller]
670
671 *) Fix potential buffer overrun for EBCDIC.
672 [Ulf Moeller]
673
674 *) Tolerate nonRepudiation as being valid for S/MIME signing and certSign
675 keyUsage if basicConstraints absent for a CA.
676 [Steve Henson]
677
678 *) Make SMIME_write_PKCS7() write mail header values with a format that
679 is more generally accepted (no spaces before the semicolon), since
680 some programs can't parse those values properly otherwise. Also make
681 sure BIO's that break lines after each write do not create invalid
682 headers.
683 [Richard Levitte]
684
685 *) Make the CRL encoding routines work with empty SEQUENCE OF. The
686 macros previously used would not encode an empty SEQUENCE OF
687 and break the signature.
688 [Steve Henson]
689 [This change does not apply to 0.9.7.]
690
691 *) Zero the premaster secret after deriving the master secret in
692 DH ciphersuites.
693 [Steve Henson]
694
695 *) Add some EVP_add_digest_alias registrations (as found in
696 OpenSSL_add_all_digests()) to SSL_library_init()
697 aka OpenSSL_add_ssl_algorithms(). This provides improved
698 compatibility with peers using X.509 certificates
699 with unconventional AlgorithmIdentifier OIDs.
700 [Bodo Moeller]
701
702 *) Fix for Irix with NO_ASM.
703 ["Bruce W. Forsberg" <bruce.forsberg@baesystems.com>]
704
705 *) ./config script fixes.
706 [Ulf Moeller, Richard Levitte]
707
708 *) Fix 'openssl passwd -1'.
709 [Bodo Moeller]
710
711 *) Change PKCS12_key_gen_asc() so it can cope with non null
712 terminated strings whose length is passed in the passlen
713 parameter, for example from PEM callbacks. This was done
714 by adding an extra length parameter to asc2uni().
715 [Steve Henson, reported by <oddissey@samsung.co.kr>]
716
717 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn
718 call failed, free the DSA structure.
719 [Bodo Moeller]
720
721 *) Fix to uni2asc() to cope with zero length Unicode strings.
722 These are present in some PKCS#12 files.
723 [Steve Henson]
724
725 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c).
726 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits
727 when writing a 32767 byte record.
728 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>]
729
730 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c),
731 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}.
732
733 (RSA objects have a reference count access to which is protected
734 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c],
735 so they are meant to be shared between threads.)
736 [Bodo Moeller, Geoff Thorpe; original patch submitted by
737 "Reddie, Steven" <Steven.Reddie@ca.com>]
738
739 *) Fix a deadlock in CRYPTO_mem_leaks().
740 [Bodo Moeller]
741
742 *) Use better test patterns in bntest.
743 [Ulf M�ller]
744
745 *) rand_win.c fix for Borland C.
746 [Ulf M�ller]
747
748 *) BN_rshift bugfix for n == 0.
749 [Bodo Moeller]
750
751 *) Add a 'bctest' script that checks for some known 'bc' bugs
752 so that 'make test' does not abort just because 'bc' is broken.
753 [Bodo Moeller]
754
755 *) Store verify_result within SSL_SESSION also for client side to
756 avoid potential security hole. (Re-used sessions on the client side
757 always resulted in verify_result==X509_V_OK, not using the original
758 result of the server certificate verification.)
759 [Lutz Jaenicke]
760
761 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type
762 SSL3_RT_APPLICATION_DATA, return 0.
763 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true.
764 [Bodo Moeller]
765
766 *) Fix SSL_peek:
767 Both ssl2_peek and ssl3_peek, which were totally broken in earlier
768 releases, have been re-implemented by renaming the previous
769 implementations of ssl2_read and ssl3_read to ssl2_read_internal
770 and ssl3_read_internal, respectively, and adding 'peek' parameters
771 to them. The new ssl[23]_{read,peek} functions are calls to
772 ssl[23]_read_internal with the 'peek' flag set appropriately.
773 A 'peek' parameter has also been added to ssl3_read_bytes, which
774 does the actual work for ssl3_read_internal.
775 [Bodo Moeller]
776
777 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling
778 the method-specific "init()" handler. Also clean up ex_data after
779 calling the method-specific "finish()" handler. Previously, this was
780 happening the other way round.
781 [Geoff Thorpe]
782
783 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16.
784 The previous value, 12, was not always sufficient for BN_mod_exp().
785 [Bodo Moeller]
786
787 *) Make sure that shared libraries get the internal name engine with
788 the full version number and not just 0. This should mark the
789 shared libraries as not backward compatible. Of course, this should
790 be changed again when we can guarantee backward binary compatibility.
791 [Richard Levitte]
792
793 *) Fix typo in get_cert_by_subject() in by_dir.c
794 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>]
795
796 *) Rework the system to generate shared libraries:
797
798 - Make note of the expected extension for the shared libraries and
799 if there is a need for symbolic links from for example libcrypto.so.0
800 to libcrypto.so.0.9.7. There is extended info in Configure for
801 that.
802
803 - Make as few rebuilds of the shared libraries as possible.
804
805 - Still avoid linking the OpenSSL programs with the shared libraries.
806
807 - When installing, install the shared libraries separately from the
808 static ones.
809 [Richard Levitte]
810
811 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument.
812
813 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new
814 and not in SSL_clear because the latter is also used by the
815 accept/connect functions; previously, the settings made by
816 SSL_set_read_ahead would be lost during the handshake.
817 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>]
818
819 *) Correct util/mkdef.pl to be selective about disabled algorithms.
820 Previously, it would create entries for disableed algorithms no
821 matter what.
822 [Richard Levitte]
823
824 *) Added several new manual pages for SSL_* function.
825 [Lutz Jaenicke]
826
827 Changes between 0.9.5a and 0.9.6 [24 Sep 2000]
828
829 *) In ssl23_get_client_hello, generate an error message when faced
830 with an initial SSL 3.0/TLS record that is too small to contain the
831 first two bytes of the ClientHello message, i.e. client_version.
832 (Note that this is a pathologic case that probably has never happened
833 in real life.) The previous approach was to use the version number
834 from the record header as a substitute; but our protocol choice
835 should not depend on that one because it is not authenticated
836 by the Finished messages.
837 [Bodo Moeller]
838
839 *) More robust randomness gathering functions for Windows.
840 [Jeffrey Altman <jaltman@columbia.edu>]
841
842 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is
843 not set then we don't setup the error code for issuer check errors
844 to avoid possibly overwriting other errors which the callback does
845 handle. If an application does set the flag then we assume it knows
846 what it is doing and can handle the new informational codes
847 appropriately.
848 [Steve Henson]
849
850 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for
851 a general "ANY" type, as such it should be able to decode anything
852 including tagged types. However it didn't check the class so it would
853 wrongly interpret tagged types in the same way as their universal
854 counterpart and unknown types were just rejected. Changed so that the
855 tagged and unknown types are handled in the same way as a SEQUENCE:
856 that is the encoding is stored intact. There is also a new type
857 "V_ASN1_OTHER" which is used when the class is not universal, in this
858 case we have no idea what the actual type is so we just lump them all
859 together.
860 [Steve Henson]
861
862 *) On VMS, stdout may very well lead to a file that is written to
863 in a record-oriented fashion. That means that every write() will
864 write a separate record, which will be read separately by the
865 programs trying to read from it. This can be very confusing.
866
867 The solution is to put a BIO filter in the way that will buffer
868 text until a linefeed is reached, and then write everything a
869 line at a time, so every record written will be an actual line,
870 not chunks of lines and not (usually doesn't happen, but I've
871 seen it once) several lines in one record. BIO_f_linebuffer() is
872 the answer.
873
874 Currently, it's a VMS-only method, because that's where it has
875 been tested well enough.
876 [Richard Levitte]
877
878 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery,
879 it can return incorrect results.
880 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a,
881 but it was in 0.9.6-beta[12].)
882 [Bodo Moeller]
883
884 *) Disable the check for content being present when verifying detached
885 signatures in pk7_smime.c. Some versions of Netscape (wrongly)
886 include zero length content when signing messages.
887 [Steve Henson]
888
889 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR
890 BIO_ctrl (for BIO pairs).
891 [Bodo M�ller]
892
893 *) Add DSO method for VMS.
894 [Richard Levitte]
895
896 *) Bug fix: Montgomery multiplication could produce results with the
897 wrong sign.
898 [Ulf M�ller]
899
900 *) Add RPM specification openssl.spec and modify it to build three
901 packages. The default package contains applications, application
902 documentation and run-time libraries. The devel package contains
903 include files, static libraries and function documentation. The
904 doc package contains the contents of the doc directory. The original
905 openssl.spec was provided by Damien Miller <djm@mindrot.org>.
906 [Richard Levitte]
907
908 *) Add a large number of documentation files for many SSL routines.
909 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
910
911 *) Add a configuration entry for Sony News 4.
912 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>]
913
914 *) Don't set the two most significant bits to one when generating a
915 random number < q in the DSA library.
916 [Ulf M�ller]
917
918 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default
919 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if
920 the underlying transport is blocking) if a handshake took place.
921 (The default behaviour is needed by applications such as s_client
922 and s_server that use select() to determine when to use SSL_read;
923 but for applications that know in advance when to expect data, it
924 just makes things more complicated.)
925 [Bodo Moeller]
926
927 *) Add RAND_egd_bytes(), which gives control over the number of bytes read
928 from EGD.
929 [Ben Laurie]
930
931 *) Add a few more EBCDIC conditionals that make `req' and `x509'
932 work better on such systems.
933 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
934
935 *) Add two demo programs for PKCS12_parse() and PKCS12_create().
936 Update PKCS12_parse() so it copies the friendlyName and the
937 keyid to the certificates aux info.
938 [Steve Henson]
939
940 *) Fix bug in PKCS7_verify() which caused an infinite loop
941 if there was more than one signature.
942 [Sven Uszpelkat <su@celocom.de>]
943
944 *) Major change in util/mkdef.pl to include extra information
945 about each symbol, as well as presentig variables as well
946 as functions. This change means that there's n more need
947 to rebuild the .num files when some algorithms are excluded.
948 [Richard Levitte]
949
950 *) Allow the verify time to be set by an application,
951 rather than always using the current time.
952 [Steve Henson]
953
954 *) Phase 2 verify code reorganisation. The certificate
955 verify code now looks up an issuer certificate by a
956 number of criteria: subject name, authority key id
957 and key usage. It also verifies self signed certificates
958 by the same criteria. The main comparison function is
959 X509_check_issued() which performs these checks.
960
961 Lot of changes were necessary in order to support this
962 without completely rewriting the lookup code.
963
964 Authority and subject key identifier are now cached.
965
966 The LHASH 'certs' is X509_STORE has now been replaced
967 by a STACK_OF(X509_OBJECT). This is mainly because an
968 LHASH can't store or retrieve multiple objects with
969 the same hash value.
970
971 As a result various functions (which were all internal
972 use only) have changed to handle the new X509_STORE
973 structure. This will break anything that messed round
974 with X509_STORE internally.
975
976 The functions X509_STORE_add_cert() now checks for an
977 exact match, rather than just subject name.
978
979 The X509_STORE API doesn't directly support the retrieval
980 of multiple certificates matching a given criteria, however
981 this can be worked round by performing a lookup first
982 (which will fill the cache with candidate certificates)
983 and then examining the cache for matches. This is probably
984 the best we can do without throwing out X509_LOOKUP
985 entirely (maybe later...).
986
987 The X509_VERIFY_CTX structure has been enhanced considerably.
988
989 All certificate lookup operations now go via a get_issuer()
990 callback. Although this currently uses an X509_STORE it
991 can be replaced by custom lookups. This is a simple way
992 to bypass the X509_STORE hackery necessary to make this
993 work and makes it possible to use more efficient techniques
994 in future. A very simple version which uses a simple
995 STACK for its trusted certificate store is also provided
996 using X509_STORE_CTX_trusted_stack().
997
998 The verify_cb() and verify() callbacks now have equivalents
999 in the X509_STORE_CTX structure.
1000
1001 X509_STORE_CTX also has a 'flags' field which can be used
1002 to customise the verify behaviour.
1003 [Steve Henson]
1004
1005 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which
1006 excludes S/MIME capabilities.
1007 [Steve Henson]
1008
1009 *) When a certificate request is read in keep a copy of the
1010 original encoding of the signed data and use it when outputing
1011 again. Signatures then use the original encoding rather than
1012 a decoded, encoded version which may cause problems if the
1013 request is improperly encoded.
1014 [Steve Henson]
1015
1016 *) For consistency with other BIO_puts implementations, call
1017 buffer_write(b, ...) directly in buffer_puts instead of calling
1018 BIO_write(b, ...).
1019
1020 In BIO_puts, increment b->num_write as in BIO_write.
1021 [Peter.Sylvester@EdelWeb.fr]
1022
1023 *) Fix BN_mul_word for the case where the word is 0. (We have to use
1024 BN_zero, we may not return a BIGNUM with an array consisting of
1025 words set to zero.)
1026 [Bodo Moeller]
1027
1028 *) Avoid calling abort() from within the library when problems are
1029 detected, except if preprocessor symbols have been defined
1030 (such as REF_CHECK, BN_DEBUG etc.).
1031 [Bodo Moeller]
1032
1033 *) New openssl application 'rsautl'. This utility can be
1034 used for low level RSA operations. DER public key
1035 BIO/fp routines also added.
1036 [Steve Henson]
1037
1038 *) New Configure entry and patches for compiling on QNX 4.
1039 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>]
1040
1041 *) A demo state-machine implementation was sponsored by
1042 Nuron (http://www.nuron.com/) and is now available in
1043 demos/state_machine.
1044 [Ben Laurie]
1045
1046 *) New options added to the 'dgst' utility for signature
1047 generation and verification.
1048 [Steve Henson]
1049
1050 *) Unrecognized PKCS#7 content types are now handled via a
1051 catch all ASN1_TYPE structure. This allows unsupported
1052 types to be stored as a "blob" and an application can
1053 encode and decode it manually.
1054 [Steve Henson]
1055
1056 *) Fix various signed/unsigned issues to make a_strex.c
1057 compile under VC++.
1058 [Oscar Jacobsson <oscar.jacobsson@celocom.com>]
1059
1060 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct
1061 length if passed a buffer. ASN1_INTEGER_to_BN failed
1062 if passed a NULL BN and its argument was negative.
1063 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>]
1064
1065 *) Modification to PKCS#7 encoding routines to output definite
1066 length encoding. Since currently the whole structures are in
1067 memory there's not real point in using indefinite length
1068 constructed encoding. However if OpenSSL is compiled with
1069 the flag PKCS7_INDEFINITE_ENCODING the old form is used.
1070 [Steve Henson]
1071
1072 *) Added BIO_vprintf() and BIO_vsnprintf().
1073 [Richard Levitte]
1074
1075 *) Added more prefixes to parse for in the the strings written
1076 through a logging bio, to cover all the levels that are available
1077 through syslog. The prefixes are now:
1078
1079 PANIC, EMERG, EMR => LOG_EMERG
1080 ALERT, ALR => LOG_ALERT
1081 CRIT, CRI => LOG_CRIT
1082 ERROR, ERR => LOG_ERR
1083 WARNING, WARN, WAR => LOG_WARNING
1084 NOTICE, NOTE, NOT => LOG_NOTICE
1085 INFO, INF => LOG_INFO
1086 DEBUG, DBG => LOG_DEBUG
1087
1088 and as before, if none of those prefixes are present at the
1089 beginning of the string, LOG_ERR is chosen.
1090
1091 On Win32, the LOG_* levels are mapped according to this:
1092
1093 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE
1094 LOG_WARNING => EVENTLOG_WARNING_TYPE
1095 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE
1096
1097 [Richard Levitte]
1098
1099 *) Made it possible to reconfigure with just the configuration
1100 argument "reconf" or "reconfigure". The command line arguments
1101 are stored in Makefile.ssl in the variable CONFIGURE_ARGS,
1102 and are retrieved from there when reconfiguring.
1103 [Richard Levitte]
1104
1105 *) MD4 implemented.
1106 [Assar Westerlund <assar@sics.se>, Richard Levitte]
1107
1108 *) Add the arguments -CAfile and -CApath to the pkcs12 utility.
1109 [Richard Levitte]
1110
1111 *) The obj_dat.pl script was messing up the sorting of object
1112 names. The reason was that it compared the quoted version
1113 of strings as a result "OCSP" > "OCSP Signing" because
1114 " > SPACE. Changed script to store unquoted versions of
1115 names and add quotes on output. It was also omitting some
1116 names from the lookup table if they were given a default
1117 value (that is if SN is missing it is given the same
1118 value as LN and vice versa), these are now added on the
1119 grounds that if an object has a name we should be able to
1120 look it up. Finally added warning output when duplicate
1121 short or long names are found.
1122 [Steve Henson]
1123
1124 *) Changes needed for Tandem NSK.
1125 [Scott Uroff <scott@xypro.com>]
1126
1127 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in
1128 RSA_padding_check_SSLv23(), special padding was never detected
1129 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol
1130 version rollback attacks was not effective.
1131
1132 In s23_clnt.c, don't use special rollback-attack detection padding
1133 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
1134 client; similarly, in s23_srvr.c, don't do the rollback check if
1135 SSL 2.0 is the only protocol enabled in the server.
1136 [Bodo Moeller]
1137
1138 *) Make it possible to get hexdumps of unprintable data with 'openssl
1139 asn1parse'. By implication, the functions ASN1_parse_dump() and
1140 BIO_dump_indent() are added.
1141 [Richard Levitte]
1142
1143 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex()
1144 these print out strings and name structures based on various
1145 flags including RFC2253 support and proper handling of
1146 multibyte characters. Added options to the 'x509' utility
1147 to allow the various flags to be set.
1148 [Steve Henson]
1149
1150 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME.
1151 Also change the functions X509_cmp_current_time() and
1152 X509_gmtime_adj() work with an ASN1_TIME structure,
1153 this will enable certificates using GeneralizedTime in validity
1154 dates to be checked.
1155 [Steve Henson]
1156
1157 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid
1158 negative public key encodings) on by default,
1159 NO_NEG_PUBKEY_BUG can be set to disable it.
1160 [Steve Henson]
1161
1162 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT
1163 content octets. An i2c_ASN1_OBJECT is unnecessary because
1164 the encoding can be trivially obtained from the structure.
1165 [Steve Henson]
1166
1167 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock),
1168 not read locks (CRYPTO_r_[un]lock).
1169 [Bodo Moeller]
1170
1171 *) A first attempt at creating official support for shared
1172 libraries through configuration. I've kept it so the
1173 default is static libraries only, and the OpenSSL programs
1174 are always statically linked for now, but there are
1175 preparations for dynamic linking in place.
1176 This has been tested on Linux and Tru64.
1177 [Richard Levitte]
1178
1179 *) Randomness polling function for Win9x, as described in:
1180 Peter Gutmann, Software Generation of Practically Strong
1181 Random Numbers.
1182 [Ulf M�ller]
1183
1184 *) Fix so PRNG is seeded in req if using an already existing
1185 DSA key.
1186 [Steve Henson]
1187
1188 *) New options to smime application. -inform and -outform
1189 allow alternative formats for the S/MIME message including
1190 PEM and DER. The -content option allows the content to be
1191 specified separately. This should allow things like Netscape
1192 form signing output easier to verify.
1193 [Steve Henson]
1194
1195 *) Fix the ASN1 encoding of tags using the 'long form'.
1196 [Steve Henson]
1197
1198 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT
1199 STRING types. These convert content octets to and from the
1200 underlying type. The actual tag and length octets are
1201 already assumed to have been read in and checked. These
1202 are needed because all other string types have virtually
1203 identical handling apart from the tag. By having versions
1204 of the ASN1 functions that just operate on content octets
1205 IMPLICIT tagging can be handled properly. It also allows
1206 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED
1207 and ASN1_INTEGER are identical apart from the tag.
1208 [Steve Henson]
1209
1210 *) Change the handling of OID objects as follows:
1211
1212 - New object identifiers are inserted in objects.txt, following
1213 the syntax given in objects.README.
1214 - objects.pl is used to process obj_mac.num and create a new
1215 obj_mac.h.
1216 - obj_dat.pl is used to create a new obj_dat.h, using the data in
1217 obj_mac.h.
1218
1219 This is currently kind of a hack, and the perl code in objects.pl
1220 isn't very elegant, but it works as I intended. The simplest way
1221 to check that it worked correctly is to look in obj_dat.h and
1222 check the array nid_objs and make sure the objects haven't moved
1223 around (this is important!). Additions are OK, as well as
1224 consistent name changes.
1225 [Richard Levitte]
1226
1227 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1').
1228 [Bodo Moeller]
1229
1230 *) Addition of the command line parameter '-rand file' to 'openssl req'.
1231 The given file adds to whatever has already been seeded into the
1232 random pool through the RANDFILE configuration file option or
1233 environment variable, or the default random state file.
1234 [Richard Levitte]
1235
1236 *) mkstack.pl now sorts each macro group into lexical order.
1237 Previously the output order depended on the order the files
1238 appeared in the directory, resulting in needless rewriting
1239 of safestack.h .
1240 [Steve Henson]
1241
1242 *) Patches to make OpenSSL compile under Win32 again. Mostly
1243 work arounds for the VC++ problem that it treats func() as
1244 func(void). Also stripped out the parts of mkdef.pl that
1245 added extra typesafe functions: these no longer exist.
1246 [Steve Henson]
1247
1248 *) Reorganisation of the stack code. The macros are now all
1249 collected in safestack.h . Each macro is defined in terms of
1250 a "stack macro" of the form SKM_<name>(type, a, b). The
1251 DEBUG_SAFESTACK is now handled in terms of function casts,
1252 this has the advantage of retaining type safety without the
1253 use of additional functions. If DEBUG_SAFESTACK is not defined
1254 then the non typesafe macros are used instead. Also modified the
1255 mkstack.pl script to handle the new form. Needs testing to see
1256 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK
1257 the default if no major problems. Similar behaviour for ASN1_SET_OF
1258 and PKCS12_STACK_OF.
1259 [Steve Henson]
1260
1261 *) When some versions of IIS use the 'NET' form of private key the
1262 key derivation algorithm is different. Normally MD5(password) is
1263 used as a 128 bit RC4 key. In the modified case
1264 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some
1265 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same
1266 as the old Netscape_RSA functions except they have an additional
1267 'sgckey' parameter which uses the modified algorithm. Also added
1268 an -sgckey command line option to the rsa utility. Thanks to
1269 Adrian Peck <bertie@ncipher.com> for posting details of the modified
1270 algorithm to openssl-dev.
1271 [Steve Henson]
1272
1273 *) The evp_local.h macros were using 'c.##kname' which resulted in
1274 invalid expansion on some systems (SCO 5.0.5 for example).
1275 Corrected to 'c.kname'.
1276 [Phillip Porch <root@theporch.com>]
1277
1278 *) New X509_get1_email() and X509_REQ_get1_email() functions that return
1279 a STACK of email addresses from a certificate or request, these look
1280 in the subject name and the subject alternative name extensions and
1281 omit any duplicate addresses.
1282 [Steve Henson]
1283
1284 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows.
1285 This makes DSA verification about 2 % faster.
1286 [Bodo Moeller]
1287
1288 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5
1289 (meaning that now 2^5 values will be precomputed, which is only 4 KB
1290 plus overhead for 1024 bit moduli).
1291 This makes exponentiations about 0.5 % faster for 1024 bit
1292 exponents (as measured by "openssl speed rsa2048").
1293 [Bodo Moeller]
1294
1295 *) Rename memory handling macros to avoid conflicts with other
1296 software:
1297 Malloc => OPENSSL_malloc
1298 Malloc_locked => OPENSSL_malloc_locked
1299 Realloc => OPENSSL_realloc
1300 Free => OPENSSL_free
1301 [Richard Levitte]
1302
1303 *) New function BN_mod_exp_mont_word for small bases (roughly 15%
1304 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange).
1305 [Bodo Moeller]
1306
1307 *) CygWin32 support.
1308 [John Jarvie <jjarvie@newsguy.com>]
1309
1310 *) The type-safe stack code has been rejigged. It is now only compiled
1311 in when OpenSSL is configured with the DEBUG_SAFESTACK option and
1312 by default all type-specific stack functions are "#define"d back to
1313 standard stack functions. This results in more streamlined output
1314 but retains the type-safety checking possibilities of the original
1315 approach.
1316 [Geoff Thorpe]
1317
1318 *) The STACK code has been cleaned up, and certain type declarations
1319 that didn't make a lot of sense have been brought in line. This has
1320 also involved a cleanup of sorts in safestack.h to more correctly
1321 map type-safe stack functions onto their plain stack counterparts.
1322 This work has also resulted in a variety of "const"ifications of
1323 lots of the code, especially "_cmp" operations which should normally
1324 be prototyped with "const" parameters anyway.
1325 [Geoff Thorpe]
1326
1327 *) When generating bytes for the first time in md_rand.c, 'stir the pool'
1328 by seeding with STATE_SIZE dummy bytes (with zero entropy count).
1329 (The PRNG state consists of two parts, the large pool 'state' and 'md',
1330 where all of 'md' is used each time the PRNG is used, but 'state'
1331 is used only indexed by a cyclic counter. As entropy may not be
1332 well distributed from the beginning, 'md' is important as a
1333 chaining variable. However, the output function chains only half
1334 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains
1335 all of 'md', and seeding with STATE_SIZE dummy bytes will result
1336 in all of 'state' being rewritten, with the new values depending
1337 on virtually all of 'md'. This overcomes the 80 bit limitation.)
1338 [Bodo Moeller]
1339
1340 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when
1341 the handshake is continued after ssl_verify_cert_chain();
1342 otherwise, if SSL_VERIFY_NONE is set, remaining error codes
1343 can lead to 'unexplainable' connection aborts later.
1344 [Bodo Moeller; problem tracked down by Lutz Jaenicke]
1345
1346 *) Major EVP API cipher revision.
1347 Add hooks for extra EVP features. This allows various cipher
1348 parameters to be set in the EVP interface. Support added for variable
1349 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and
1350 setting of RC2 and RC5 parameters.
1351
1352 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length
1353 ciphers.
1354
1355 Remove lots of duplicated code from the EVP library. For example *every*
1356 cipher init() function handles the 'iv' in the same way according to the
1357 cipher mode. They also all do nothing if the 'key' parameter is NULL and
1358 for CFB and OFB modes they zero ctx->num.
1359
1360 New functionality allows removal of S/MIME code RC2 hack.
1361
1362 Most of the routines have the same form and so can be declared in terms
1363 of macros.
1364
1365 By shifting this to the top level EVP_CipherInit() it can be removed from
1366 all individual ciphers. If the cipher wants to handle IVs or keys
1367 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT
1368 flags.
1369
1370 Change lots of functions like EVP_EncryptUpdate() to now return a
1371 value: although software versions of the algorithms cannot fail
1372 any installed hardware versions can.
1373 [Steve Henson]
1374
1375 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if
1376 this option is set, tolerate broken clients that send the negotiated
1377 protocol version number instead of the requested protocol version
1378 number.
1379 [Bodo Moeller]
1380
1381 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag;
1382 i.e. non-zero for export ciphersuites, zero otherwise.
1383 Previous versions had this flag inverted, inconsistent with
1384 rsa_tmp_cb (..._TMP_RSA_CB).
1385 [Bodo Moeller; problem reported by Amit Chopra]
1386
1387 *) Add missing DSA library text string. Work around for some IIS
1388 key files with invalid SEQUENCE encoding.
1389 [Steve Henson]
1390
1391 *) Add a document (doc/standards.txt) that list all kinds of standards
1392 and so on that are implemented in OpenSSL.
1393 [Richard Levitte]
1394
1395 *) Enhance c_rehash script. Old version would mishandle certificates
1396 with the same subject name hash and wouldn't handle CRLs at all.
1397 Added -fingerprint option to crl utility, to support new c_rehash
1398 features.
1399 [Steve Henson]
1400
1401 *) Eliminate non-ANSI declarations in crypto.h and stack.h.
1402 [Ulf M�ller]
1403
1404 *) Fix for SSL server purpose checking. Server checking was
1405 rejecting certificates which had extended key usage present
1406 but no ssl client purpose.
1407 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>]
1408
1409 *) Make PKCS#12 code work with no password. The PKCS#12 spec
1410 is a little unclear about how a blank password is handled.
1411 Since the password in encoded as a BMPString with terminating
1412 double NULL a zero length password would end up as just the
1413 double NULL. However no password at all is different and is
1414 handled differently in the PKCS#12 key generation code. NS
1415 treats a blank password as zero length. MSIE treats it as no
1416 password on export: but it will try both on import. We now do
1417 the same: PKCS12_parse() tries zero length and no password if
1418 the password is set to "" or NULL (NULL is now a valid password:
1419 it wasn't before) as does the pkcs12 application.
1420 [Steve Henson]
1421
1422 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use
1423 perror when PEM_read_bio_X509_REQ fails, the error message must
1424 be obtained from the error queue.
1425 [Bodo Moeller]
1426
1427 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing
1428 it in ERR_remove_state if appropriate, and change ERR_get_state
1429 accordingly to avoid race conditions (this is necessary because
1430 thread_hash is no longer constant once set).
1431 [Bodo Moeller]
1432
1433 *) Bugfix for linux-elf makefile.one.
1434 [Ulf M�ller]
1435
1436 *) RSA_get_default_method() will now cause a default
1437 RSA_METHOD to be chosen if one doesn't exist already.
1438 Previously this was only set during a call to RSA_new()
1439 or RSA_new_method(NULL) meaning it was possible for
1440 RSA_get_default_method() to return NULL.
1441 [Geoff Thorpe]
1442
1443 *) Added native name translation to the existing DSO code
1444 that will convert (if the flag to do so is set) filenames
1445 that are sufficiently small and have no path information
1446 into a canonical native form. Eg. "blah" converted to
1447 "libblah.so" or "blah.dll" etc.
1448 [Geoff Thorpe]
1449
1450 *) New function ERR_error_string_n(e, buf, len) which is like
1451 ERR_error_string(e, buf), but writes at most 'len' bytes
1452 including the 0 terminator. For ERR_error_string_n, 'buf'
1453 may not be NULL.
1454 [Damien Miller <djm@mindrot.org>, Bodo Moeller]
1455
1456 *) CONF library reworked to become more general. A new CONF
1457 configuration file reader "class" is implemented as well as a
1458 new functions (NCONF_*, for "New CONF") to handle it. The now
1459 old CONF_* functions are still there, but are reimplemented to
1460 work in terms of the new functions. Also, a set of functions
1461 to handle the internal storage of the configuration data is
1462 provided to make it easier to write new configuration file
1463 reader "classes" (I can definitely see something reading a
1464 configuration file in XML format, for example), called _CONF_*,
1465 or "the configuration storage API"...
1466
1467 The new configuration file reading functions are:
1468
1469 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio,
1470 NCONF_get_section, NCONF_get_string, NCONF_get_numbre
1471
1472 NCONF_default, NCONF_WIN32
1473
1474 NCONF_dump_fp, NCONF_dump_bio
1475
1476 NCONF_default and NCONF_WIN32 are method (or "class") choosers,
1477 NCONF_new creates a new CONF object. This works in the same way
1478 as other interfaces in OpenSSL, like the BIO interface.
1479 NCONF_dump_* dump the internal storage of the configuration file,
1480 which is useful for debugging. All other functions take the same
1481 arguments as the old CONF_* functions wth the exception of the
1482 first that must be a `CONF *' instead of a `LHASH *'.
1483
1484 To make it easer to use the new classes with the old CONF_* functions,
1485 the function CONF_set_default_method is provided.
1486 [Richard Levitte]
1487
1488 *) Add '-tls1' option to 'openssl ciphers', which was already
1489 mentioned in the documentation but had not been implemented.
1490 (This option is not yet really useful because even the additional
1491 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.)
1492 [Bodo Moeller]
1493
1494 *) Initial DSO code added into libcrypto for letting OpenSSL (and
1495 OpenSSL-based applications) load shared libraries and bind to
1496 them in a portable way.
1497 [Geoff Thorpe, with contributions from Richard Levitte]
1498
1499 Changes between 0.9.5 and 0.9.5a [1 Apr 2000]
1500
1501 *) Make sure _lrotl and _lrotr are only used with MSVC.
1502
1503 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status
1504 (the default implementation of RAND_status).
1505
1506 *) Rename openssl x509 option '-crlext', which was added in 0.9.5,
1507 to '-clrext' (= clear extensions), as intended and documented.
1508 [Bodo Moeller; inconsistency pointed out by Michael Attili
1509 <attili@amaxo.com>]
1510
1511 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length
1512 was larger than the MD block size.
1513 [Steve Henson, pointed out by Yost William <YostW@tce.com>]
1514
1515 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument
1516 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set()
1517 using the passed key: if the passed key was a private key the result
1518 of X509_print(), for example, would be to print out all the private key
1519 components.
1520 [Steve Henson]
1521
1522 *) des_quad_cksum() byte order bug fix.
1523 [Ulf M�ller, using the problem description in krb4-0.9.7, where
1524 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>]
1525
1526 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly
1527 discouraged.
1528 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>]
1529
1530 *) For easily testing in shell scripts whether some command
1531 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX'
1532 returns with exit code 0 iff no command of the given name is available.
1533 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases,
1534 the output goes to stdout and nothing is printed to stderr.
1535 Additional arguments are always ignored.
1536
1537 Since for each cipher there is a command of the same name,
1538 the 'no-cipher' compilation switches can be tested this way.
1539
1540 ('openssl no-XXX' is not able to detect pseudo-commands such
1541 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.)
1542 [Bodo Moeller]
1543
1544 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration.
1545 [Bodo Moeller]
1546
1547 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE
1548 is set; it will be thrown away anyway because each handshake creates
1549 its own key.
1550 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition
1551 to parameters -- in previous versions (since OpenSSL 0.9.3) the
1552 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining
1553 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro.
1554 [Bodo Moeller]
1555
1556 *) New s_client option -ign_eof: EOF at stdin is ignored, and
1557 'Q' and 'R' lose their special meanings (quit/renegotiate).
1558 This is part of what -quiet does; unlike -quiet, -ign_eof
1559 does not suppress any output.
1560 [Richard Levitte]
1561
1562 *) Add compatibility options to the purpose and trust code. The
1563 purpose X509_PURPOSE_ANY is "any purpose" which automatically
1564 accepts a certificate or CA, this was the previous behaviour,
1565 with all the associated security issues.
1566
1567 X509_TRUST_COMPAT is the old trust behaviour: only and
1568 automatically trust self signed roots in certificate store. A
1569 new trust setting X509_TRUST_DEFAULT is used to specify that
1570 a purpose has no associated trust setting and it should instead
1571 use the value in the default purpose.
1572 [Steve Henson]
1573
1574 *) Fix the PKCS#8 DSA private key code so it decodes keys again
1575 and fix a memory leak.
1576 [Steve Henson]
1577
1578 *) In util/mkerr.pl (which implements 'make errors'), preserve
1579 reason strings from the previous version of the .c file, as
1580 the default to have only downcase letters (and digits) in
1581 automatically generated reasons codes is not always appropriate.
1582 [Bodo Moeller]
1583
1584 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table
1585 using strerror. Previously, ERR_reason_error_string() returned
1586 library names as reason strings for SYSerr; but SYSerr is a special
1587 case where small numbers are errno values, not library numbers.
1588 [Bodo Moeller]
1589
1590 *) Add '-dsaparam' option to 'openssl dhparam' application. This
1591 converts DSA parameters into DH parameters. (When creating parameters,
1592 DSA_generate_parameters is used.)
1593 [Bodo Moeller]
1594
1595 *) Include 'length' (recommended exponent length) in C code generated
1596 by 'openssl dhparam -C'.
1597 [Bodo Moeller]
1598
1599 *) The second argument to set_label in perlasm was already being used
1600 so couldn't be used as a "file scope" flag. Moved to third argument
1601 which was free.
1602 [Steve Henson]
1603
1604 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes
1605 instead of RAND_bytes for encryption IVs and salts.
1606 [Bodo Moeller]
1607
1608 *) Include RAND_status() into RAND_METHOD instead of implementing
1609 it only for md_rand.c Otherwise replacing the PRNG by calling
1610 RAND_set_rand_method would be impossible.
1611 [Bodo Moeller]
1612
1613 *) Don't let DSA_generate_key() enter an infinite loop if the random
1614 number generation fails.
1615 [Bodo Moeller]
1616
1617 *) New 'rand' application for creating pseudo-random output.
1618 [Bodo Moeller]
1619
1620 *) Added configuration support for Linux/IA64
1621 [Rolf Haberrecker <rolf@suse.de>]
1622
1623 *) Assembler module support for Mingw32.
1624 [Ulf M�ller]
1625
1626 *) Shared library support for HPUX (in shlib/).
1627 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous]
1628
1629 *) Shared library support for Solaris gcc.
1630 [Lutz Behnke <behnke@trustcenter.de>]
1631
1632 Changes between 0.9.4 and 0.9.5 [28 Feb 2000]
1633
1634 *) PKCS7_encrypt() was adding text MIME headers twice because they
1635 were added manually and by SMIME_crlf_copy().
1636 [Steve Henson]
1637
1638 *) In bntest.c don't call BN_rand with zero bits argument.
1639 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>]
1640
1641 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n]
1642 case was implemented. This caused BN_div_recp() to fail occasionally.
1643 [Ulf M�ller]
1644
1645 *) Add an optional second argument to the set_label() in the perl
1646 assembly language builder. If this argument exists and is set
1647 to 1 it signals that the assembler should use a symbol whose
1648 scope is the entire file, not just the current function. This
1649 is needed with MASM which uses the format label:: for this scope.
1650 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>]
1651
1652 *) Change the ASN1 types so they are typedefs by default. Before
1653 almost all types were #define'd to ASN1_STRING which was causing
1654 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING)
1655 for example.
1656 [Steve Henson]
1657
1658 *) Change names of new functions to the new get1/get0 naming
1659 convention: After 'get1', the caller owns a reference count
1660 and has to call ..._free; 'get0' returns a pointer to some
1661 data structure without incrementing reference counters.
1662 (Some of the existing 'get' functions increment a reference
1663 counter, some don't.)
1664 Similarly, 'set1' and 'add1' functions increase reference
1665 counters or duplicate objects.
1666 [Steve Henson]
1667
1668 *) Allow for the possibility of temp RSA key generation failure:
1669 the code used to assume it always worked and crashed on failure.
1670 [Steve Henson]
1671
1672 *) Fix potential buffer overrun problem in BIO_printf().
1673 [Ulf M�ller, using public domain code by Patrick Powell; problem
1674 pointed out by David Sacerdote <das33@cornell.edu>]
1675
1676 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions
1677 RAND_egd() and RAND_status(). In the command line application,
1678 the EGD socket can be specified like a seed file using RANDFILE
1679 or -rand.
1680 [Ulf M�ller]
1681
1682 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures.
1683 Some CAs (e.g. Verisign) distribute certificates in this form.
1684 [Steve Henson]
1685
1686 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher
1687 list to exclude them. This means that no special compilation option
1688 is needed to use anonymous DH: it just needs to be included in the
1689 cipher list.
1690 [Steve Henson]
1691
1692 *) Change the EVP_MD_CTX_type macro so its meaning consistent with
1693 EVP_MD_type. The old functionality is available in a new macro called
1694 EVP_MD_md(). Change code that uses it and update docs.
1695 [Steve Henson]
1696
1697 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions
1698 where the 'void *' argument is replaced by a function pointer argument.
1699 Previously 'void *' was abused to point to functions, which works on
1700 many platforms, but is not correct. As these functions are usually
1701 called by macros defined in OpenSSL header files, most source code
1702 should work without changes.
1703 [Richard Levitte]
1704
1705 *) <openssl/opensslconf.h> (which is created by Configure) now contains
1706 sections with information on -D... compiler switches used for
1707 compiling the library so that applications can see them. To enable
1708 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES
1709 must be defined. E.g.,
1710 #define OPENSSL_ALGORITHM_DEFINES
1711 #include <openssl/opensslconf.h>
1712 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc.
1713 [Richard Levitte, Ulf and Bodo M�ller]
1714
1715 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS
1716 record layer.
1717 [Bodo Moeller]
1718
1719 *) Change the 'other' type in certificate aux info to a STACK_OF
1720 X509_ALGOR. Although not an AlgorithmIdentifier as such it has
1721 the required ASN1 format: arbitrary types determined by an OID.
1722 [Steve Henson]
1723
1724 *) Add some PEM_write_X509_REQ_NEW() functions and a command line
1725 argument to 'req'. This is not because the function is newer or
1726 better than others it just uses the work 'NEW' in the certificate
1727 request header lines. Some software needs this.
1728 [Steve Henson]
1729
1730 *) Reorganise password command line arguments: now passwords can be
1731 obtained from various sources. Delete the PEM_cb function and make
1732 it the default behaviour: i.e. if the callback is NULL and the
1733 usrdata argument is not NULL interpret it as a null terminated pass
1734 phrase. If usrdata and the callback are NULL then the pass phrase
1735 is prompted for as usual.
1736 [Steve Henson]
1737
1738 *) Add support for the Compaq Atalla crypto accelerator. If it is installed,
1739 the support is automatically enabled. The resulting binaries will
1740 autodetect the card and use it if present.
1741 [Ben Laurie and Compaq Inc.]
1742
1743 *) Work around for Netscape hang bug. This sends certificate request
1744 and server done in one record. Since this is perfectly legal in the
1745 SSL/TLS protocol it isn't a "bug" option and is on by default. See
1746 the bugs/SSLv3 entry for more info.
1747 [Steve Henson]
1748
1749 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround.
1750 [Andy Polyakov]
1751
1752 *) Add -rand argument to smime and pkcs12 applications and read/write
1753 of seed file.
1754 [Steve Henson]
1755
1756 *) New 'passwd' tool for crypt(3) and apr1 password hashes.
1757 [Bodo Moeller]
1758
1759 *) Add command line password options to the remaining applications.
1760 [Steve Henson]
1761
1762 *) Bug fix for BN_div_recp() for numerators with an even number of
1763 bits.
1764 [Ulf M�ller]
1765
1766 *) More tests in bntest.c, and changed test_bn output.
1767 [Ulf M�ller]
1768
1769 *) ./config recognizes MacOS X now.
1770 [Andy Polyakov]
1771
1772 *) Bug fix for BN_div() when the first words of num and divsor are
1773 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0).
1774 [Ulf M�ller]
1775
1776 *) Add support for various broken PKCS#8 formats, and command line
1777 options to produce them.
1778 [Steve Henson]
1779
1780 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to
1781 get temporary BIGNUMs from a BN_CTX.
1782 [Ulf M�ller]
1783
1784 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont()
1785 for p == 0.
1786 [Ulf M�ller]
1787
1788 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and
1789 include a #define from the old name to the new. The original intent
1790 was that statically linked binaries could for example just call
1791 SSLeay_add_all_ciphers() to just add ciphers to the table and not
1792 link with digests. This never worked becayse SSLeay_add_all_digests()
1793 and SSLeay_add_all_ciphers() were in the same source file so calling
1794 one would link with the other. They are now in separate source files.
1795 [Steve Henson]
1796
1797 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'.
1798 [Steve Henson]
1799
1800 *) Use a less unusual form of the Miller-Rabin primality test (it used
1801 a binary algorithm for exponentiation integrated into the Miller-Rabin
1802 loop, our standard modexp algorithms are faster).
1803 [Bodo Moeller]
1804
1805 *) Support for the EBCDIC character set completed.
1806 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>]
1807
1808 *) Source code cleanups: use const where appropriate, eliminate casts,
1809 use void * instead of char * in lhash.
1810 [Ulf M�ller]
1811
1812 *) Bugfix: ssl3_send_server_key_exchange was not restartable
1813 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of
1814 this the server could overwrite ephemeral keys that the client
1815 has already seen).
1816 [Bodo Moeller]
1817
1818 *) Turn DSA_is_prime into a macro that calls BN_is_prime,
1819 using 50 iterations of the Rabin-Miller test.
1820
1821 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50
1822 iterations of the Rabin-Miller test as required by the appendix
1823 to FIPS PUB 186[-1]) instead of DSA_is_prime.
1824 As BN_is_prime_fasttest includes trial division, DSA parameter
1825 generation becomes much faster.
1826
1827 This implies a change for the callback functions in DSA_is_prime
1828 and DSA_generate_parameters: The callback function is called once
1829 for each positive witness in the Rabin-Miller test, not just
1830 occasionally in the inner loop; and the parameters to the
1831 callback function now provide an iteration count for the outer
1832 loop rather than for the current invocation of the inner loop.
1833 DSA_generate_parameters additionally can call the callback
1834 function with an 'iteration count' of -1, meaning that a
1835 candidate has passed the trial division test (when q is generated
1836 from an application-provided seed, trial division is skipped).
1837 [Bodo Moeller]
1838
1839 *) New function BN_is_prime_fasttest that optionally does trial
1840 division before starting the Rabin-Miller test and has
1841 an additional BN_CTX * argument (whereas BN_is_prime always
1842 has to allocate at least one BN_CTX).
1843 'callback(1, -1, cb_arg)' is called when a number has passed the
1844 trial division stage.
1845 [Bodo Moeller]
1846
1847 *) Fix for bug in CRL encoding. The validity dates weren't being handled
1848 as ASN1_TIME.
1849 [Steve Henson]
1850
1851 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file.
1852 [Steve Henson]
1853
1854 *) New function BN_pseudo_rand().
1855 [Ulf M�ller]
1856
1857 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable)
1858 bignum version of BN_from_montgomery() with the working code from
1859 SSLeay 0.9.0 (the word based version is faster anyway), and clean up
1860 the comments.
1861 [Ulf M�ller]
1862
1863 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that
1864 made it impossible to use the same SSL_SESSION data structure in
1865 SSL2 clients in multiple threads.
1866 [Bodo Moeller]
1867
1868 *) The return value of RAND_load_file() no longer counts bytes obtained
1869 by stat(). RAND_load_file(..., -1) is new and uses the complete file
1870 to seed the PRNG (previously an explicit byte count was required).
1871 [Ulf M�ller, Bodo M�ller]
1872
1873 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes
1874 used (char *) instead of (void *) and had casts all over the place.
1875 [Steve Henson]
1876
1877 *) Make BN_generate_prime() return NULL on error if ret!=NULL.
1878 [Ulf M�ller]
1879
1880 *) Retain source code compatibility for BN_prime_checks macro:
1881 BN_is_prime(..., BN_prime_checks, ...) now uses
1882 BN_prime_checks_for_size to determine the appropriate number of
1883 Rabin-Miller iterations.
1884 [Ulf M�ller]
1885
1886 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to
1887 DH_CHECK_P_NOT_SAFE_PRIME.
1888 (Check if this is true? OpenPGP calls them "strong".)
1889 [Ulf M�ller]
1890
1891 *) Merge the functionality of "dh" and "gendh" programs into a new program
1892 "dhparam". The old programs are retained for now but will handle DH keys
1893 (instead of parameters) in future.
1894 [Steve Henson]
1895
1896 *) Make the ciphers, s_server and s_client programs check the return values
1897 when a new cipher list is set.
1898 [Steve Henson]
1899
1900 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit
1901 ciphers. Before when the 56bit ciphers were enabled the sorting was
1902 wrong.
1903
1904 The syntax for the cipher sorting has been extended to support sorting by
1905 cipher-strength (using the strength_bits hard coded in the tables).
1906 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod).
1907
1908 Fix a bug in the cipher-command parser: when supplying a cipher command
1909 string with an "undefined" symbol (neither command nor alphanumeric
1910 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now
1911 an error is flagged.
1912
1913 Due to the strength-sorting extension, the code of the
1914 ssl_create_cipher_list() function was completely rearranged. I hope that
1915 the readability was also increased :-)
1916 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>]
1917
1918 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1
1919 for the first serial number and places 2 in the serial number file. This
1920 avoids problems when the root CA is created with serial number zero and
1921 the first user certificate has the same issuer name and serial number
1922 as the root CA.
1923 [Steve Henson]
1924
1925 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses
1926 the new code. Add documentation for this stuff.
1927 [Steve Henson]
1928
1929 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from
1930 X509_*() to X509at_*() on the grounds that they don't handle X509
1931 structures and behave in an analagous way to the X509v3 functions:
1932 they shouldn't be called directly but wrapper functions should be used
1933 instead.
1934
1935 So we also now have some wrapper functions that call the X509at functions
1936 when passed certificate requests. (TO DO: similar things can be done with
1937 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other
1938 things. Some of these need some d2i or i2d and print functionality
1939 because they handle more complex structures.)
1940 [Steve Henson]
1941
1942 *) Add missing #ifndefs that caused missing symbols when building libssl
1943 as a shared library without RSA. Use #ifndef NO_SSL2 instead of
1944 NO_RSA in ssl/s2*.c.
1945 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf M�ller]
1946
1947 *) Precautions against using the PRNG uninitialized: RAND_bytes() now
1948 has a return value which indicates the quality of the random data
1949 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's
1950 error queue. New function RAND_pseudo_bytes() generates output that is
1951 guaranteed to be unique but not unpredictable. RAND_add is like
1952 RAND_seed, but takes an extra argument for an entropy estimate
1953 (RAND_seed always assumes full entropy).
1954 [Ulf M�ller]
1955
1956 *) Do more iterations of Rabin-Miller probable prime test (specifically,
1957 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes
1958 instead of only 2 for all lengths; see BN_prime_checks_for_size definition
1959 in crypto/bn/bn_prime.c for the complete table). This guarantees a
1960 false-positive rate of at most 2^-80 for random input.
1961 [Bodo Moeller]
1962
1963 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs.
1964 [Bodo Moeller]
1965
1966 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain
1967 in the 0.9.5 release), this returns the chain
1968 from an X509_CTX structure with a dup of the stack and all
1969 the X509 reference counts upped: so the stack will exist
1970 after X509_CTX_cleanup() has been called. Modify pkcs12.c
1971 to use this.
1972
1973 Also make SSL_SESSION_print() print out the verify return
1974 code.
1975 [Steve Henson]
1976
1977 *) Add manpage for the pkcs12 command. Also change the default
1978 behaviour so MAC iteration counts are used unless the new
1979 -nomaciter option is used. This improves file security and
1980 only older versions of MSIE (4.0 for example) need it.
1981 [Steve Henson]
1982
1983 *) Honor the no-xxx Configure options when creating .DEF files.
1984 [Ulf M�ller]
1985
1986 *) Add PKCS#10 attributes to field table: challengePassword,
1987 unstructuredName and unstructuredAddress. These are taken from
1988 draft PKCS#9 v2.0 but are compatible with v1.2 provided no
1989 international characters are used.
1990
1991 More changes to X509_ATTRIBUTE code: allow the setting of types
1992 based on strings. Remove the 'loc' parameter when adding
1993 attributes because these will be a SET OF encoding which is sorted
1994 in ASN1 order.
1995 [Steve Henson]
1996
1997 *) Initial changes to the 'req' utility to allow request generation
1998 automation. This will allow an application to just generate a template
1999 file containing all the field values and have req construct the
2000 request.
2001
2002 Initial support for X509_ATTRIBUTE handling. Stacks of these are
2003 used all over the place including certificate requests and PKCS#7
2004 structures. They are currently handled manually where necessary with
2005 some primitive wrappers for PKCS#7. The new functions behave in a
2006 manner analogous to the X509 extension functions: they allow
2007 attributes to be looked up by NID and added.
2008
2009 Later something similar to the X509V3 code would be desirable to
2010 automatically handle the encoding, decoding and printing of the
2011 more complex types. The string types like challengePassword can
2012 be handled by the string table functions.
2013
2014 Also modified the multi byte string table handling. Now there is
2015 a 'global mask' which masks out certain types. The table itself
2016 can use the flag STABLE_NO_MASK to ignore the mask setting: this
2017 is useful when for example there is only one permissible type
2018 (as in countryName) and using the mask might result in no valid
2019 types at all.
2020 [Steve Henson]
2021
2022 *) Clean up 'Finished' handling, and add functions SSL_get_finished and
2023 SSL_get_peer_finished to allow applications to obtain the latest
2024 Finished messages sent to the peer or expected from the peer,
2025 respectively. (SSL_get_peer_finished is usually the Finished message
2026 actually received from the peer, otherwise the protocol will be aborted.)
2027
2028 As the Finished message are message digests of the complete handshake
2029 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can
2030 be used for external authentication procedures when the authentication
2031 provided by SSL/TLS is not desired or is not enough.
2032 [Bodo Moeller]
2033
2034 *) Enhanced support for Alpha Linux is added. Now ./config checks if
2035 the host supports BWX extension and if Compaq C is present on the
2036 $PATH. Just exploiting of the BWX extension results in 20-30%
2037 performance kick for some algorithms, e.g. DES and RC4 to mention
2038 a couple. Compaq C in turn generates ~20% faster code for MD5 and
2039 SHA1.
2040 [Andy Polyakov]
2041
2042 *) Add support for MS "fast SGC". This is arguably a violation of the
2043 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with
2044 weak crypto and after checking the certificate is SGC a second one
2045 with strong crypto. MS SGC stops the first handshake after receiving
2046 the server certificate message and sends a second client hello. Since
2047 a server will typically do all the time consuming operations before
2048 expecting any further messages from the client (server key exchange
2049 is the most expensive) there is little difference between the two.
2050
2051 To get OpenSSL to support MS SGC we have to permit a second client
2052 hello message after we have sent server done. In addition we have to
2053 reset the MAC if we do get this second client hello.
2054 [Steve Henson]
2055
2056 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide
2057 if a DER encoded private key is RSA or DSA traditional format. Changed
2058 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional"
2059 format DER encoded private key. Newer code should use PKCS#8 format which
2060 has the key type encoded in the ASN1 structure. Added DER private key
2061 support to pkcs8 application.
2062 [Steve Henson]
2063
2064 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous
2065 ciphersuites has been selected (as required by the SSL 3/TLS 1
2066 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT
2067 is set, we interpret this as a request to violate the specification
2068 (the worst that can happen is a handshake failure, and 'correct'
2069 behaviour would result in a handshake failure anyway).
2070 [Bodo Moeller]
2071
2072 *) In SSL_CTX_add_session, take into account that there might be multiple
2073 SSL_SESSION structures with the same session ID (e.g. when two threads
2074 concurrently obtain them from an external cache).
2075 The internal cache can handle only one SSL_SESSION with a given ID,
2076 so if there's a conflict, we now throw out the old one to achieve
2077 consistency.
2078 [Bodo Moeller]
2079
2080 *) Add OIDs for idea and blowfish in CBC mode. This will allow both
2081 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to
2082 some routines that use cipher OIDs: some ciphers do not have OIDs
2083 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for
2084 example.
2085 [Steve Henson]
2086
2087 *) Simplify the trust setting structure and code. Now we just have
2088 two sequences of OIDs for trusted and rejected settings. These will
2089 typically have values the same as the extended key usage extension
2090 and any application specific purposes.
2091
2092 The trust checking code now has a default behaviour: it will just
2093 check for an object with the same NID as the passed id. Functions can
2094 be provided to override either the default behaviour or the behaviour
2095 for a given id. SSL client, server and email already have functions
2096 in place for compatibility: they check the NID and also return "trusted"
2097 if the certificate is self signed.
2098 [Steve Henson]
2099
2100 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the
2101 traditional format into an EVP_PKEY structure.
2102 [Steve Henson]
2103
2104 *) Add a password callback function PEM_cb() which either prompts for
2105 a password if usr_data is NULL or otherwise assumes it is a null
2106 terminated password. Allow passwords to be passed on command line
2107 environment or config files in a few more utilities.
2108 [Steve Henson]
2109
2110 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private
2111 keys. Add some short names for PKCS#8 PBE algorithms and allow them
2112 to be specified on the command line for the pkcs8 and pkcs12 utilities.
2113 Update documentation.
2114 [Steve Henson]
2115
2116 *) Support for ASN1 "NULL" type. This could be handled before by using
2117 ASN1_TYPE but there wasn't any function that would try to read a NULL
2118 and produce an error if it couldn't. For compatibility we also have
2119 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and
2120 don't allocate anything because they don't need to.
2121 [Steve Henson]
2122
2123 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS
2124 for details.
2125 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>]
2126
2127 *) Rebuild of the memory allocation routines used by OpenSSL code and
2128 possibly others as well. The purpose is to make an interface that
2129 provide hooks so anyone can build a separate set of allocation and
2130 deallocation routines to be used by OpenSSL, for example memory
2131 pool implementations, or something else, which was previously hard
2132 since Malloc(), Realloc() and Free() were defined as macros having
2133 the values malloc, realloc and free, respectively (except for Win32
2134 compilations). The same is provided for memory debugging code.
2135 OpenSSL already comes with functionality to find memory leaks, but
2136 this gives people a chance to debug other memory problems.
2137
2138 With these changes, a new set of functions and macros have appeared:
2139
2140 CRYPTO_set_mem_debug_functions() [F]
2141 CRYPTO_get_mem_debug_functions() [F]
2142 CRYPTO_dbg_set_options() [F]
2143 CRYPTO_dbg_get_options() [F]
2144 CRYPTO_malloc_debug_init() [M]
2145
2146 The memory debug functions are NULL by default, unless the library
2147 is compiled with CRYPTO_MDEBUG or friends is defined. If someone
2148 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which
2149 gives the standard debugging functions that come with OpenSSL) or
2150 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions
2151 provided by the library user) must be used. When the standard
2152 debugging functions are used, CRYPTO_dbg_set_options can be used to
2153 request additional information:
2154 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting
2155 the CRYPTO_MDEBUG_xxx macro when compiling the library.
2156
2157 Also, things like CRYPTO_set_mem_functions will always give the
2158 expected result (the new set of functions is used for allocation
2159 and deallocation) at all times, regardless of platform and compiler
2160 options.
2161
2162 To finish it up, some functions that were never use in any other
2163 way than through macros have a new API and new semantic:
2164
2165 CRYPTO_dbg_malloc()
2166 CRYPTO_dbg_realloc()
2167 CRYPTO_dbg_free()
2168
2169 All macros of value have retained their old syntax.
2170 [Richard Levitte and Bodo Moeller]
2171
2172 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the
2173 ordering of SMIMECapabilities wasn't in "strength order" and there
2174 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature
2175 algorithm.
2176 [Steve Henson]
2177
2178 *) Some ASN1 types with illegal zero length encoding (INTEGER,
2179 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines.
2180 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson]
2181
2182 *) Merge in my S/MIME library for OpenSSL. This provides a simple
2183 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough
2184 functionality to handle multipart/signed properly) and a utility
2185 called 'smime' to call all this stuff. This is based on code I
2186 originally wrote for Celo who have kindly allowed it to be
2187 included in OpenSSL.
2188 [Steve Henson]
2189
2190 *) Add variants des_set_key_checked and des_set_key_unchecked of
2191 des_set_key (aka des_key_sched). Global variable des_check_key
2192 decides which of these is called by des_set_key; this way
2193 des_check_key behaves as it always did, but applications and
2194 the library itself, which was buggy for des_check_key == 1,
2195 have a cleaner way to pick the version they need.
2196 [Bodo Moeller]
2197
2198 *) New function PKCS12_newpass() which changes the password of a
2199 PKCS12 structure.
2200 [Steve Henson]
2201
2202 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and
2203 dynamic mix. In both cases the ids can be used as an index into the
2204 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add()
2205 functions so they accept a list of the field values and the
2206 application doesn't need to directly manipulate the X509_TRUST
2207 structure.
2208 [Steve Henson]
2209
2210 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't
2211 need initialising.
2212 [Steve Henson]
2213
2214 *) Modify the way the V3 extension code looks up extensions. This now
2215 works in a similar way to the object code: we have some "standard"
2216 extensions in a static table which is searched with OBJ_bsearch()
2217 and the application can add dynamic ones if needed. The file
2218 crypto/x509v3/ext_dat.h now has the info: this file needs to be
2219 updated whenever a new extension is added to the core code and kept
2220 in ext_nid order. There is a simple program 'tabtest.c' which checks
2221 this. New extensions are not added too often so this file can readily
2222 be maintained manually.
2223
2224 There are two big advantages in doing things this way. The extensions
2225 can be looked up immediately and no longer need to be "added" using
2226 X509V3_add_standard_extensions(): this function now does nothing.
2227 [Side note: I get *lots* of email saying the extension code doesn't
2228 work because people forget to call this function]
2229 Also no dynamic allocation is done unless new extensions are added:
2230 so if we don't add custom extensions there is no need to call
2231 X509V3_EXT_cleanup().
2232 [Steve Henson]
2233
2234 *) Modify enc utility's salting as follows: make salting the default. Add a
2235 magic header, so unsalted files fail gracefully instead of just decrypting
2236 to garbage. This is because not salting is a big security hole, so people
2237 should be discouraged from doing it.
2238 [Ben Laurie]
2239
2240 *) Fixes and enhancements to the 'x509' utility. It allowed a message
2241 digest to be passed on the command line but it only used this
2242 parameter when signing a certificate. Modified so all relevant
2243 operations are affected by the digest parameter including the
2244 -fingerprint and -x509toreq options. Also -x509toreq choked if a
2245 DSA key was used because it didn't fix the digest.
2246 [Steve Henson]
2247
2248 *) Initial certificate chain verify code. Currently tests the untrusted
2249 certificates for consistency with the verify purpose (which is set
2250 when the X509_STORE_CTX structure is set up) and checks the pathlength.
2251
2252 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour:
2253 this is because it will reject chains with invalid extensions whereas
2254 every previous version of OpenSSL and SSLeay made no checks at all.
2255
2256 Trust code: checks the root CA for the relevant trust settings. Trust
2257 settings have an initial value consistent with the verify purpose: e.g.
2258 if the verify purpose is for SSL client use it expects the CA to be
2259 trusted for SSL client use. However the default value can be changed to
2260 permit custom trust settings: one example of this would be to only trust
2261 certificates from a specific "secure" set of CAs.
2262
2263 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions
2264 which should be used for version portability: especially since the
2265 verify structure is likely to change more often now.
2266
2267 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions
2268 to set them. If not set then assume SSL clients will verify SSL servers
2269 and vice versa.
2270
2271 Two new options to the verify program: -untrusted allows a set of
2272 untrusted certificates to be passed in and -purpose which sets the
2273 intended purpose of the certificate. If a purpose is set then the
2274 new chain verify code is used to check extension consistency.
2275 [Steve Henson]
2276
2277 *) Support for the authority information access extension.
2278 [Steve Henson]
2279
2280 *) Modify RSA and DSA PEM read routines to transparently handle
2281 PKCS#8 format private keys. New *_PUBKEY_* functions that handle
2282 public keys in a format compatible with certificate
2283 SubjectPublicKeyInfo structures. Unfortunately there were already
2284 functions called *_PublicKey_* which used various odd formats so
2285 these are retained for compatibility: however the DSA variants were
2286 never in a public release so they have been deleted. Changed dsa/rsa
2287 utilities to handle the new format: note no releases ever handled public
2288 keys so we should be OK.
2289
2290 The primary motivation for this change is to avoid the same fiasco
2291 that dogs private keys: there are several incompatible private key
2292 formats some of which are standard and some OpenSSL specific and
2293 require various evil hacks to allow partial transparent handling and
2294 even then it doesn't work with DER formats. Given the option anything
2295 other than PKCS#8 should be dumped: but the other formats have to
2296 stay in the name of compatibility.
2297
2298 With public keys and the benefit of hindsight one standard format
2299 is used which works with EVP_PKEY, RSA or DSA structures: though
2300 it clearly returns an error if you try to read the wrong kind of key.
2301
2302 Added a -pubkey option to the 'x509' utility to output the public key.
2303 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*()
2304 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add
2305 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*())
2306 that do the same as the EVP_PKEY_assign_*() except they up the
2307 reference count of the added key (they don't "swallow" the
2308 supplied key).
2309 [Steve Henson]
2310
2311 *) Fixes to crypto/x509/by_file.c the code to read in certificates and
2312 CRLs would fail if the file contained no certificates or no CRLs:
2313 added a new function to read in both types and return the number
2314 read: this means that if none are read it will be an error. The
2315 DER versions of the certificate and CRL reader would always fail
2316 because it isn't possible to mix certificates and CRLs in DER format
2317 without choking one or the other routine. Changed this to just read
2318 a certificate: this is the best we can do. Also modified the code
2319 in apps/verify.c to take notice of return codes: it was previously
2320 attempting to read in certificates from NULL pointers and ignoring
2321 any errors: this is one reason why the cert and CRL reader seemed
2322 to work. It doesn't check return codes from the default certificate
2323 routines: these may well fail if the certificates aren't installed.
2324 [Steve Henson]
2325
2326 *) Code to support otherName option in GeneralName.
2327 [Steve Henson]
2328
2329 *) First update to verify code. Change the verify utility
2330 so it warns if it is passed a self signed certificate:
2331 for consistency with the normal behaviour. X509_verify
2332 has been modified to it will now verify a self signed
2333 certificate if *exactly* the same certificate appears
2334 in the store: it was previously impossible to trust a
2335 single self signed certificate. This means that:
2336 openssl verify ss.pem
2337 now gives a warning about a self signed certificate but
2338 openssl verify -CAfile ss.pem ss.pem
2339 is OK.
2340 [Steve Henson]
2341
2342 *) For servers, store verify_result in SSL_SESSION data structure
2343 (and add it to external session representation).
2344 This is needed when client certificate verifications fails,
2345 but an application-provided verification callback (set by
2346 SSL_CTX_set_cert_verify_callback) allows accepting the session
2347 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK
2348 but returns 1): When the session is reused, we have to set
2349 ssl->verify_result to the appropriate error code to avoid
2350 security holes.
2351 [Bodo Moeller, problem pointed out by Lutz Jaenicke]
2352
2353 *) Fix a bug in the new PKCS#7 code: it didn't consider the
2354 case in PKCS7_dataInit() where the signed PKCS7 structure
2355 didn't contain any existing data because it was being created.
2356 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson]
2357
2358 *) Add a salt to the key derivation routines in enc.c. This
2359 forms the first 8 bytes of the encrypted file. Also add a
2360 -S option to allow a salt to be input on the command line.
2361 [Steve Henson]
2362
2363 *) New function X509_cmp(). Oddly enough there wasn't a function
2364 to compare two certificates. We do this by working out the SHA1
2365 hash and comparing that. X509_cmp() will be needed by the trust
2366 code.
2367 [Steve Henson]
2368
2369 *) SSL_get1_session() is like SSL_get_session(), but increments
2370 the reference count in the SSL_SESSION returned.
2371 [Geoff Thorpe <geoff@eu.c2.net>]
2372
2373 *) Fix for 'req': it was adding a null to request attributes.
2374 Also change the X509_LOOKUP and X509_INFO code to handle
2375 certificate auxiliary information.
2376 [Steve Henson]
2377
2378 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document
2379 the 'enc' command.
2380 [Steve Henson]
2381
2382 *) Add the possibility to add extra information to the memory leak
2383 detecting output, to form tracebacks, showing from where each
2384 allocation was originated: CRYPTO_push_info("constant string") adds
2385 the string plus current file name and line number to a per-thread
2386 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info()
2387 is like calling CYRPTO_pop_info() until the stack is empty.
2388 Also updated memory leak detection code to be multi-thread-safe.
2389 [Richard Levitte]
2390
2391 *) Add options -text and -noout to pkcs7 utility and delete the
2392 encryption options which never did anything. Update docs.
2393 [Steve Henson]
2394
2395 *) Add options to some of the utilities to allow the pass phrase
2396 to be included on either the command line (not recommended on
2397 OSes like Unix) or read from the environment. Update the
2398 manpages and fix a few bugs.
2399 [Steve Henson]
2400
2401 *) Add a few manpages for some of the openssl commands.
2402 [Steve Henson]
2403
2404 *) Fix the -revoke option in ca. It was freeing up memory twice,
2405 leaking and not finding already revoked certificates.
2406 [Steve Henson]
2407
2408 *) Extensive changes to support certificate auxiliary information.
2409 This involves the use of X509_CERT_AUX structure and X509_AUX
2410 functions. An X509_AUX function such as PEM_read_X509_AUX()
2411 can still read in a certificate file in the usual way but it
2412 will also read in any additional "auxiliary information". By
2413 doing things this way a fair degree of compatibility can be
2414 retained: existing certificates can have this information added
2415 using the new 'x509' options.
2416
2417 Current auxiliary information includes an "alias" and some trust
2418 settings. The trust settings will ultimately be used in enhanced
2419 certificate chain verification routines: currently a certificate
2420 can only be trusted if it is self signed and then it is trusted
2421 for all purposes.
2422 [Steve Henson]
2423
2424 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD).
2425 The problem was that one of the replacement routines had not been working
2426 since SSLeay releases. For now the offending routine has been replaced
2427 with non-optimised assembler. Even so, this now gives around 95%
2428 performance improvement for 1024 bit RSA signs.
2429 [Mark Cox]
2430
2431 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2
2432 handling. Most clients have the effective key size in bits equal to
2433 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key.
2434 A few however don't do this and instead use the size of the decrypted key
2435 to determine the RC2 key length and the AlgorithmIdentifier to determine
2436 the effective key length. In this case the effective key length can still
2437 be 40 bits but the key length can be 168 bits for example. This is fixed
2438 by manually forcing an RC2 key into the EVP_PKEY structure because the
2439 EVP code can't currently handle unusual RC2 key sizes: it always assumes
2440 the key length and effective key length are equal.
2441 [Steve Henson]
2442
2443 *) Add a bunch of functions that should simplify the creation of
2444 X509_NAME structures. Now you should be able to do:
2445 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0);
2446 and have it automatically work out the correct field type and fill in
2447 the structures. The more adventurous can try:
2448 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0);
2449 and it will (hopefully) work out the correct multibyte encoding.
2450 [Steve Henson]
2451
2452 *) Change the 'req' utility to use the new field handling and multibyte
2453 copy routines. Before the DN field creation was handled in an ad hoc
2454 way in req, ca, and x509 which was rather broken and didn't support
2455 BMPStrings or UTF8Strings. Since some software doesn't implement
2456 BMPStrings or UTF8Strings yet, they can be enabled using the config file
2457 using the dirstring_type option. See the new comment in the default
2458 openssl.cnf for more info.
2459 [Steve Henson]
2460
2461 *) Make crypto/rand/md_rand.c more robust:
2462 - Assure unique random numbers after fork().
2463 - Make sure that concurrent threads access the global counter and
2464 md serializably so that we never lose entropy in them
2465 or use exactly the same state in multiple threads.
2466 Access to the large state is not always serializable because
2467 the additional locking could be a performance killer, and
2468 md should be large enough anyway.
2469 [Bodo Moeller]
2470
2471 *) New file apps/app_rand.c with commonly needed functionality
2472 for handling the random seed file.
2473
2474 Use the random seed file in some applications that previously did not:
2475 ca,
2476 dsaparam -genkey (which also ignored its '-rand' option),
2477 s_client,
2478 s_server,
2479 x509 (when signing).
2480 Except on systems with /dev/urandom, it is crucial to have a random
2481 seed file at least for key creation, DSA signing, and for DH exchanges;
2482 for RSA signatures we could do without one.
2483
2484 gendh and gendsa (unlike genrsa) used to read only the first byte
2485 of each file listed in the '-rand' option. The function as previously
2486 found in genrsa is now in app_rand.c and is used by all programs
2487 that support '-rand'.
2488 [Bodo Moeller]
2489
2490 *) In RAND_write_file, use mode 0600 for creating files;
2491 don't just chmod when it may be too late.
2492 [Bodo Moeller]
2493
2494 *) Report an error from X509_STORE_load_locations
2495 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed.
2496 [Bill Perry]
2497
2498 *) New function ASN1_mbstring_copy() this copies a string in either
2499 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format
2500 into an ASN1_STRING type. A mask of permissible types is passed
2501 and it chooses the "minimal" type to use or an error if not type
2502 is suitable.
2503 [Steve Henson]
2504
2505 *) Add function equivalents to the various macros in asn1.h. The old
2506 macros are retained with an M_ prefix. Code inside the library can
2507 use the M_ macros. External code (including the openssl utility)
2508 should *NOT* in order to be "shared library friendly".
2509 [Steve Henson]
2510
2511 *) Add various functions that can check a certificate's extensions
2512 to see if it usable for various purposes such as SSL client,
2513 server or S/MIME and CAs of these types. This is currently
2514 VERY EXPERIMENTAL but will ultimately be used for certificate chain
2515 verification. Also added a -purpose flag to x509 utility to
2516 print out all the purposes.
2517 [Steve Henson]
2518
2519 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated
2520 functions.
2521 [Steve Henson]
2522
2523 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search
2524 for, obtain and decode and extension and obtain its critical flag.
2525 This allows all the necessary extension code to be handled in a
2526 single function call.
2527 [Steve Henson]
2528
2529 *) RC4 tune-up featuring 30-40% performance improvement on most RISC
2530 platforms. See crypto/rc4/rc4_enc.c for further details.
2531 [Andy Polyakov]
2532
2533 *) New -noout option to asn1parse. This causes no output to be produced
2534 its main use is when combined with -strparse and -out to extract data
2535 from a file (which may not be in ASN.1 format).
2536 [Steve Henson]
2537
2538 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer
2539 when producing the local key id.
2540 [Richard Levitte <levitte@stacken.kth.se>]
2541
2542 *) New option -dhparam in s_server. This allows a DH parameter file to be
2543 stated explicitly. If it is not stated then it tries the first server
2544 certificate file. The previous behaviour hard coded the filename
2545 "server.pem".
2546 [Steve Henson]
2547
2548 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow
2549 a public key to be input or output. For example:
2550 openssl rsa -in key.pem -pubout -out pubkey.pem
2551 Also added necessary DSA public key functions to handle this.
2552 [Steve Henson]
2553
2554 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained
2555 in the message. This was handled by allowing
2556 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it.
2557 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>]
2558
2559 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null
2560 to the end of the strings whereas this didn't. This would cause problems
2561 if strings read with d2i_ASN1_bytes() were later modified.
2562 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>]
2563
2564 *) Fix for base64 decode bug. When a base64 bio reads only one line of
2565 data and it contains EOF it will end up returning an error. This is
2566 caused by input 46 bytes long. The cause is due to the way base64
2567 BIOs find the start of base64 encoded data. They do this by trying a
2568 trial decode on each line until they find one that works. When they
2569 do a flag is set and it starts again knowing it can pass all the
2570 data directly through the decoder. Unfortunately it doesn't reset
2571 the context it uses. This means that if EOF is reached an attempt
2572 is made to pass two EOFs through the context and this causes the
2573 resulting error. This can also cause other problems as well. As is
2574 usual with these problems it takes *ages* to find and the fix is
2575 trivial: move one line.
2576 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ]
2577
2578 *) Ugly workaround to get s_client and s_server working under Windows. The
2579 old code wouldn't work because it needed to select() on sockets and the
2580 tty (for keypresses and to see if data could be written). Win32 only
2581 supports select() on sockets so we select() with a 1s timeout on the
2582 sockets and then see if any characters are waiting to be read, if none
2583 are present then we retry, we also assume we can always write data to
2584 the tty. This isn't nice because the code then blocks until we've
2585 received a complete line of data and it is effectively polling the
2586 keyboard at 1s intervals: however it's quite a bit better than not
2587 working at all :-) A dedicated Windows application might handle this
2588 with an event loop for example.
2589 [Steve Henson]
2590
2591 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign
2592 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions
2593 will be called when RSA_sign() and RSA_verify() are used. This is useful
2594 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available.
2595 For this to work properly RSA_public_decrypt() and RSA_private_encrypt()
2596 should *not* be used: RSA_sign() and RSA_verify() must be used instead.
2597 This necessitated the support of an extra signature type NID_md5_sha1
2598 for SSL signatures and modifications to the SSL library to use it instead
2599 of calling RSA_public_decrypt() and RSA_private_encrypt().
2600 [Steve Henson]
2601
2602 *) Add new -verify -CAfile and -CApath options to the crl program, these
2603 will lookup a CRL issuers certificate and verify the signature in a
2604 similar way to the verify program. Tidy up the crl program so it
2605 no longer accesses structures directly. Make the ASN1 CRL parsing a bit
2606 less strict. It will now permit CRL extensions even if it is not
2607 a V2 CRL: this will allow it to tolerate some broken CRLs.
2608 [Steve Henson]
2609
2610 *) Initialize all non-automatic variables each time one of the openssl
2611 sub-programs is started (this is necessary as they may be started
2612 multiple times from the "OpenSSL>" prompt).
2613 [Lennart Bang, Bodo Moeller]
2614
2615 *) Preliminary compilation option RSA_NULL which disables RSA crypto without
2616 removing all other RSA functionality (this is what NO_RSA does). This
2617 is so (for example) those in the US can disable those operations covered
2618 by the RSA patent while allowing storage and parsing of RSA keys and RSA
2619 key generation.
2620 [Steve Henson]
2621
2622 *) Non-copying interface to BIO pairs.
2623 (still largely untested)
2624 [Bodo Moeller]
2625
2626 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive
2627 ASCII string. This was handled independently in various places before.
2628 [Steve Henson]
2629
2630 *) New functions UTF8_getc() and UTF8_putc() that parse and generate
2631 UTF8 strings a character at a time.
2632 [Steve Henson]
2633
2634 *) Use client_version from client hello to select the protocol
2635 (s23_srvr.c) and for RSA client key exchange verification
2636 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications.
2637 [Bodo Moeller]
2638
2639 *) Add various utility functions to handle SPKACs, these were previously
2640 handled by poking round in the structure internals. Added new function
2641 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to
2642 print, verify and generate SPKACs. Based on an original idea from
2643 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified.
2644 [Steve Henson]
2645
2646 *) RIPEMD160 is operational on all platforms and is back in 'make test'.
2647 [Andy Polyakov]
2648
2649 *) Allow the config file extension section to be overwritten on the
2650 command line. Based on an original idea from Massimiliano Pala
2651 <madwolf@comune.modena.it>. The new option is called -extensions
2652 and can be applied to ca, req and x509. Also -reqexts to override
2653 the request extensions in req and -crlexts to override the crl extensions
2654 in ca.
2655 [Steve Henson]
2656
2657 *) Add new feature to the SPKAC handling in ca. Now you can include
2658 the same field multiple times by preceding it by "XXXX." for example:
2659 1.OU="Unit name 1"
2660 2.OU="Unit name 2"
2661 this is the same syntax as used in the req config file.
2662 [Steve Henson]
2663
2664 *) Allow certificate extensions to be added to certificate requests. These
2665 are specified in a 'req_extensions' option of the req section of the
2666 config file. They can be printed out with the -text option to req but
2667 are otherwise ignored at present.
2668 [Steve Henson]
2669
2670 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first
2671 data read consists of only the final block it would not decrypted because
2672 EVP_CipherUpdate() would correctly report zero bytes had been decrypted.
2673 A misplaced 'break' also meant the decrypted final block might not be
2674 copied until the next read.
2675 [Steve Henson]
2676
2677 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added
2678 a few extra parameters to the DH structure: these will be useful if
2679 for example we want the value of 'q' or implement X9.42 DH.
2680 [Steve Henson]
2681
2682 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and
2683 provides hooks that allow the default DSA functions or functions on a
2684 "per key" basis to be replaced. This allows hardware acceleration and
2685 hardware key storage to be handled without major modification to the
2686 library. Also added low level modexp hooks and CRYPTO_EX structure and
2687 associated functions.
2688 [Steve Henson]
2689
2690 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO
2691 as "read only": it can't be written to and the buffer it points to will
2692 not be freed. Reading from a read only BIO is much more efficient than
2693 a normal memory BIO. This was added because there are several times when
2694 an area of memory needs to be read from a BIO. The previous method was
2695 to create a memory BIO and write the data to it, this results in two
2696 copies of the data and an O(n^2) reading algorithm. There is a new
2697 function BIO_new_mem_buf() which creates a read only memory BIO from
2698 an area of memory. Also modified the PKCS#7 routines to use read only
2699 memory BIOs.
2700 [Steve Henson]
2701
2702 *) Bugfix: ssl23_get_client_hello did not work properly when called in
2703 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of
2704 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read,
2705 but a retry condition occured while trying to read the rest.
2706 [Bodo Moeller]
2707
2708 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as
2709 NID_pkcs7_encrypted by default: this was wrong since this should almost
2710 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle
2711 the encrypted data type: this is a more sensible place to put it and it
2712 allows the PKCS#12 code to be tidied up that duplicated this
2713 functionality.
2714 [Steve Henson]
2715
2716 *) Changed obj_dat.pl script so it takes its input and output files on
2717 the command line. This should avoid shell escape redirection problems
2718 under Win32.
2719 [Steve Henson]
2720
2721 *) Initial support for certificate extension requests, these are included
2722 in things like Xenroll certificate requests. Included functions to allow
2723 extensions to be obtained and added.
2724 [Steve Henson]
2725
2726 *) -crlf option to s_client and s_server for sending newlines as
2727 CRLF (as required by many protocols).
2728 [Bodo Moeller]
2729
2730 Changes between 0.9.3a and 0.9.4 [09 Aug 1999]
2731
2732 *) Install libRSAglue.a when OpenSSL is built with RSAref.
2733 [Ralf S. Engelschall]
2734
2735 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency.
2736 [Andrija Antonijevic <TheAntony2@bigfoot.com>]
2737
2738 *) Fix -startdate and -enddate (which was missing) arguments to 'ca'
2739 program.
2740 [Steve Henson]
2741
2742 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as
2743 DH parameters/keys (q is lost during that conversion, but the resulting
2744 DH parameters contain its length).
2745
2746 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is
2747 much faster than DH_generate_parameters (which creates parameters
2748 where p = 2*q + 1), and also the smaller q makes DH computations
2749 much more efficient (160-bit exponentiation instead of 1024-bit
2750 exponentiation); so this provides a convenient way to support DHE
2751 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of
2752 utter importance to use
2753 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2754 or
2755 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE);
2756 when such DH parameters are used, because otherwise small subgroup
2757 attacks may become possible!
2758 [Bodo Moeller]
2759
2760 *) Avoid memory leak in i2d_DHparams.
2761 [Bodo Moeller]
2762
2763 *) Allow the -k option to be used more than once in the enc program:
2764 this allows the same encrypted message to be read by multiple recipients.
2765 [Steve Henson]
2766
2767 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts
2768 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then
2769 it will always use the numerical form of the OID, even if it has a short
2770 or long name.
2771 [Steve Henson]
2772
2773 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp
2774 method only got called if p,q,dmp1,dmq1,iqmp components were present,
2775 otherwise bn_mod_exp was called. In the case of hardware keys for example
2776 no private key components need be present and it might store extra data
2777 in the RSA structure, which cannot be accessed from bn_mod_exp.
2778 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for
2779 private key operations.
2780 [Steve Henson]
2781
2782 *) Added support for SPARC Linux.
2783 [Andy Polyakov]
2784
2785 *) pem_password_cb function type incompatibly changed from
2786 typedef int pem_password_cb(char *buf, int size, int rwflag);
2787 to
2788 ....(char *buf, int size, int rwflag, void *userdata);
2789 so that applications can pass data to their callbacks:
2790 The PEM[_ASN1]_{read,write}... functions and macros now take an
2791 additional void * argument, which is just handed through whenever
2792 the password callback is called.
2793 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller]
2794
2795 New function SSL_CTX_set_default_passwd_cb_userdata.
2796
2797 Compatibility note: As many C implementations push function arguments
2798 onto the stack in reverse order, the new library version is likely to
2799 interoperate with programs that have been compiled with the old
2800 pem_password_cb definition (PEM_whatever takes some data that
2801 happens to be on the stack as its last argument, and the callback
2802 just ignores this garbage); but there is no guarantee whatsoever that
2803 this will work.
2804
2805 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=...
2806 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused
2807 problems not only on Windows, but also on some Unix platforms.
2808 To avoid problematic command lines, these definitions are now in an
2809 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl
2810 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds).
2811 [Bodo Moeller]
2812
2813 *) MIPS III/IV assembler module is reimplemented.
2814 [Andy Polyakov]
2815
2816 *) More DES library cleanups: remove references to srand/rand and
2817 delete an unused file.
2818 [Ulf M�ller]
2819
2820 *) Add support for the the free Netwide assembler (NASM) under Win32,
2821 since not many people have MASM (ml) and it can be hard to obtain.
2822 This is currently experimental but it seems to work OK and pass all
2823 the tests. Check out INSTALL.W32 for info.
2824 [Steve Henson]
2825
2826 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections
2827 without temporary keys kept an extra copy of the server key,
2828 and connections with temporary keys did not free everything in case
2829 of an error.
2830 [Bodo Moeller]
2831
2832 *) New function RSA_check_key and new openssl rsa option -check
2833 for verifying the consistency of RSA keys.
2834 [Ulf Moeller, Bodo Moeller]
2835
2836 *) Various changes to make Win32 compile work:
2837 1. Casts to avoid "loss of data" warnings in p5_crpt2.c
2838 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned
2839 comparison" warnings.
2840 3. Add sk_<TYPE>_sort to DEF file generator and do make update.
2841 [Steve Henson]
2842
2843 *) Add a debugging option to PKCS#5 v2 key generation function: when
2844 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and
2845 derived keys are printed to stderr.
2846 [Steve Henson]
2847
2848 *) Copy the flags in ASN1_STRING_dup().
2849 [Roman E. Pavlov <pre@mo.msk.ru>]
2850
2851 *) The x509 application mishandled signing requests containing DSA
2852 keys when the signing key was also DSA and the parameters didn't match.
2853
2854 It was supposed to omit the parameters when they matched the signing key:
2855 the verifying software was then supposed to automatically use the CA's
2856 parameters if they were absent from the end user certificate.
2857
2858 Omitting parameters is no longer recommended. The test was also
2859 the wrong way round! This was probably due to unusual behaviour in
2860 EVP_cmp_parameters() which returns 1 if the parameters match.
2861 This meant that parameters were omitted when they *didn't* match and
2862 the certificate was useless. Certificates signed with 'ca' didn't have
2863 this bug.
2864 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>]
2865
2866 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems.
2867 The interface is as follows:
2868 Applications can use
2869 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(),
2870 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop();
2871 "off" is now the default.
2872 The library internally uses
2873 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(),
2874 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on()
2875 to disable memory-checking temporarily.
2876
2877 Some inconsistent states that previously were possible (and were
2878 even the default) are now avoided.
2879
2880 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time
2881 with each memory chunk allocated; this is occasionally more helpful
2882 than just having a counter.
2883
2884 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID.
2885
2886 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future
2887 extensions.
2888 [Bodo Moeller]
2889
2890 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX),
2891 which largely parallels "options", but is for changing API behaviour,
2892 whereas "options" are about protocol behaviour.
2893 Initial "mode" flags are:
2894
2895 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when
2896 a single record has been written.
2897 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write
2898 retries use the same buffer location.
2899 (But all of the contents must be
2900 copied!)
2901 [Bodo Moeller]
2902
2903 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options
2904 worked.
2905
2906 *) Fix problems with no-hmac etc.
2907 [Ulf M�ller, pointed out by Brian Wellington <bwelling@tislabs.com>]
2908
2909 *) New functions RSA_get_default_method(), RSA_set_method() and
2910 RSA_get_method(). These allows replacement of RSA_METHODs without having
2911 to mess around with the internals of an RSA structure.
2912 [Steve Henson]
2913
2914 *) Fix memory leaks in DSA_do_sign and DSA_is_prime.
2915 Also really enable memory leak checks in openssl.c and in some
2916 test programs.
2917 [Chad C. Mulligan, Bodo Moeller]
2918
2919 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess
2920 up the length of negative integers. This has now been simplified to just
2921 store the length when it is first determined and use it later, rather
2922 than trying to keep track of where data is copied and updating it to
2923 point to the end.
2924 [Steve Henson, reported by Brien Wheeler
2925 <bwheeler@authentica-security.com>]
2926
2927 *) Add a new function PKCS7_signatureVerify. This allows the verification
2928 of a PKCS#7 signature but with the signing certificate passed to the
2929 function itself. This contrasts with PKCS7_dataVerify which assumes the
2930 certificate is present in the PKCS#7 structure. This isn't always the
2931 case: certificates can be omitted from a PKCS#7 structure and be
2932 distributed by "out of band" means (such as a certificate database).
2933 [Steve Henson]
2934
2935 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the
2936 function prototypes in pem.h, also change util/mkdef.pl to add the
2937 necessary function names.
2938 [Steve Henson]
2939
2940 *) mk1mf.pl (used by Windows builds) did not properly read the
2941 options set by Configure in the top level Makefile, and Configure
2942 was not even able to write more than one option correctly.
2943 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended.
2944 [Bodo Moeller]
2945
2946 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config
2947 file to be loaded from a BIO or FILE pointer. The BIO version will
2948 for example allow memory BIOs to contain config info.
2949 [Steve Henson]
2950
2951 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS.
2952 Whoever hopes to achieve shared-library compatibility across versions
2953 must use this, not the compile-time macro.
2954 (Exercise 0.9.4: Which is the minimum library version required by
2955 such programs?)
2956 Note: All this applies only to multi-threaded programs, others don't
2957 need locks.
2958 [Bodo Moeller]
2959
2960 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests
2961 through a BIO pair triggered the default case, i.e.
2962 SSLerr(...,SSL_R_UNKNOWN_STATE).
2963 [Bodo Moeller]
2964
2965 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications
2966 can use the SSL library even if none of the specific BIOs is
2967 appropriate.
2968 [Bodo Moeller]
2969
2970 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value
2971 for the encoded length.
2972 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>]
2973
2974 *) Add initial documentation of the X509V3 functions.
2975 [Steve Henson]
2976
2977 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and
2978 PEM_write_bio_PKCS8PrivateKey() that are equivalent to
2979 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more
2980 secure PKCS#8 private key format with a high iteration count.
2981 [Steve Henson]
2982
2983 *) Fix determination of Perl interpreter: A perl or perl5
2984 _directory_ in $PATH was also accepted as the interpreter.
2985 [Ralf S. Engelschall]
2986
2987 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking
2988 wrong with it but it was very old and did things like calling
2989 PEM_ASN1_read() directly and used MD5 for the hash not to mention some
2990 unusual formatting.
2991 [Steve Henson]
2992
2993 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed
2994 to use the new extension code.
2995 [Steve Henson]
2996
2997 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c
2998 with macros. This should make it easier to change their form, add extra
2999 arguments etc. Fix a few PEM prototypes which didn't have cipher as a
3000 constant.
3001 [Steve Henson]
3002
3003 *) Add to configuration table a new entry that can specify an alternative
3004 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep,
3005 according to Mark Crispin <MRC@Panda.COM>.
3006 [Bodo Moeller]
3007
3008#if 0
3009 *) DES CBC did not update the IV. Weird.
3010 [Ben Laurie]
3011#else
3012 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does.
3013 Changing the behaviour of the former might break existing programs --
3014 where IV updating is needed, des_ncbc_encrypt can be used.
3015#endif
3016
3017 *) When bntest is run from "make test" it drives bc to check its
3018 calculations, as well as internally checking them. If an internal check
3019 fails, it needs to cause bc to give a non-zero result or make test carries
3020 on without noticing the failure. Fixed.
3021 [Ben Laurie]
3022
3023 *) DES library cleanups.
3024 [Ulf M�ller]
3025
3026 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be
3027 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit
3028 ciphers. NOTE: although the key derivation function has been verified
3029 against some published test vectors it has not been extensively tested
3030 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use
3031 of v2.0.
3032 [Steve Henson]
3033
3034 *) Instead of "mkdir -p", which is not fully portable, use new
3035 Perl script "util/mkdir-p.pl".
3036 [Bodo Moeller]
3037
3038 *) Rewrite the way password based encryption (PBE) is handled. It used to
3039 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter
3040 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms
3041 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now
3042 the 'parameter' field of the AlgorithmIdentifier is passed to the
3043 underlying key generation function so it must do its own ASN1 parsing.
3044 This has also changed the EVP_PBE_CipherInit() function which now has a
3045 'parameter' argument instead of literal salt and iteration count values
3046 and the function EVP_PBE_ALGOR_CipherInit() has been deleted.
3047 [Steve Henson]
3048
3049 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms
3050 and PKCS#8 functionality. New 'pkcs8' application linked to openssl.
3051 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE
3052 KEY" because this clashed with PKCS#8 unencrypted string. Since this
3053 value was just used as a "magic string" and not used directly its
3054 value doesn't matter.
3055 [Steve Henson]
3056
3057 *) Introduce some semblance of const correctness to BN. Shame C doesn't
3058 support mutable.
3059 [Ben Laurie]
3060
3061 *) "linux-sparc64" configuration (ultrapenguin).
3062 [Ray Miller <ray.miller@oucs.ox.ac.uk>]
3063 "linux-sparc" configuration.
3064 [Christian Forster <fo@hawo.stw.uni-erlangen.de>]
3065
3066 *) config now generates no-xxx options for missing ciphers.
3067 [Ulf M�ller]
3068
3069 *) Support the EBCDIC character set (work in progress).
3070 File ebcdic.c not yet included because it has a different license.
3071 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3072
3073 *) Support BS2000/OSD-POSIX.
3074 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>]
3075
3076 *) Make callbacks for key generation use void * instead of char *.
3077 [Ben Laurie]
3078
3079 *) Make S/MIME samples compile (not yet tested).
3080 [Ben Laurie]
3081
3082 *) Additional typesafe stacks.
3083 [Ben Laurie]
3084
3085 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x).
3086 [Bodo Moeller]
3087
3088
3089 Changes between 0.9.3 and 0.9.3a [29 May 1999]
3090
3091 *) New configuration variant "sco5-gcc".
3092
3093 *) Updated some demos.
3094 [Sean O Riordain, Wade Scholine]
3095
3096 *) Add missing BIO_free at exit of pkcs12 application.
3097 [Wu Zhigang]
3098
3099 *) Fix memory leak in conf.c.
3100 [Steve Henson]
3101
3102 *) Updates for Win32 to assembler version of MD5.
3103 [Steve Henson]
3104
3105 *) Set #! path to perl in apps/der_chop to where we found it
3106 instead of using a fixed path.
3107 [Bodo Moeller]
3108
3109 *) SHA library changes for irix64-mips4-cc.
3110 [Andy Polyakov]
3111
3112 *) Improvements for VMS support.
3113 [Richard Levitte]
3114
3115
3116 Changes between 0.9.2b and 0.9.3 [24 May 1999]
3117
3118 *) Bignum library bug fix. IRIX 6 passes "make test" now!
3119 This also avoids the problems with SC4.2 and unpatched SC5.
3120 [Andy Polyakov <appro@fy.chalmers.se>]
3121
3122 *) New functions sk_num, sk_value and sk_set to replace the previous macros.
3123 These are required because of the typesafe stack would otherwise break
3124 existing code. If old code used a structure member which used to be STACK
3125 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with
3126 sk_num or sk_value it would produce an error because the num, data members
3127 are not present in STACK_OF. Now it just produces a warning. sk_set
3128 replaces the old method of assigning a value to sk_value
3129 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code
3130 that does this will no longer work (and should use sk_set instead) but
3131 this could be regarded as a "questionable" behaviour anyway.
3132 [Steve Henson]
3133
3134 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now
3135 correctly handle encrypted S/MIME data.
3136 [Steve Henson]
3137
3138 *) Change type of various DES function arguments from des_cblock
3139 (which means, in function argument declarations, pointer to char)
3140 to des_cblock * (meaning pointer to array with 8 char elements),
3141 which allows the compiler to do more typechecking; it was like
3142 that back in SSLeay, but with lots of ugly casts.
3143
3144 Introduce new type const_des_cblock.
3145 [Bodo Moeller]
3146
3147 *) Reorganise the PKCS#7 library and get rid of some of the more obvious
3148 problems: find RecipientInfo structure that matches recipient certificate
3149 and initialise the ASN1 structures properly based on passed cipher.
3150 [Steve Henson]
3151
3152 *) Belatedly make the BN tests actually check the results.
3153 [Ben Laurie]
3154
3155 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion
3156 to and from BNs: it was completely broken. New compilation option
3157 NEG_PUBKEY_BUG to allow for some broken certificates that encode public
3158 key elements as negative integers.
3159 [Steve Henson]
3160
3161 *) Reorganize and speed up MD5.
3162 [Andy Polyakov <appro@fy.chalmers.se>]
3163
3164 *) VMS support.
3165 [Richard Levitte <richard@levitte.org>]
3166
3167 *) New option -out to asn1parse to allow the parsed structure to be
3168 output to a file. This is most useful when combined with the -strparse
3169 option to examine the output of things like OCTET STRINGS.
3170 [Steve Henson]
3171
3172 *) Make SSL library a little more fool-proof by not requiring any longer
3173 that SSL_set_{accept,connect}_state be called before
3174 SSL_{accept,connect} may be used (SSL_set_..._state is omitted
3175 in many applications because usually everything *appeared* to work as
3176 intended anyway -- now it really works as intended).
3177 [Bodo Moeller]
3178
3179 *) Move openssl.cnf out of lib/.
3180 [Ulf M�ller]
3181
3182 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall
3183 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes
3184 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+
3185 [Ralf S. Engelschall]
3186
3187 *) Various fixes to the EVP and PKCS#7 code. It may now be able to
3188 handle PKCS#7 enveloped data properly.
3189 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve]
3190
3191 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of
3192 copying pointers. The cert_st handling is changed by this in
3193 various ways (and thus what used to be known as ctx->default_cert
3194 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert
3195 any longer when s->cert does not give us what we need).
3196 ssl_cert_instantiate becomes obsolete by this change.
3197 As soon as we've got the new code right (possibly it already is?),
3198 we have solved a couple of bugs of the earlier code where s->cert
3199 was used as if it could not have been shared with other SSL structures.
3200
3201 Note that using the SSL API in certain dirty ways now will result
3202 in different behaviour than observed with earlier library versions:
3203 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx)
3204 does not influence s as it used to.
3205
3206 In order to clean up things more thoroughly, inside SSL_SESSION
3207 we don't use CERT any longer, but a new structure SESS_CERT
3208 that holds per-session data (if available); currently, this is
3209 the peer's certificate chain and, for clients, the server's certificate
3210 and temporary key. CERT holds only those values that can have
3211 meaningful defaults in an SSL_CTX.
3212 [Bodo Moeller]
3213
3214 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure
3215 from the internal representation. Various PKCS#7 fixes: remove some
3216 evil casts and set the enc_dig_alg field properly based on the signing
3217 key type.
3218 [Steve Henson]
3219
3220 *) Allow PKCS#12 password to be set from the command line or the
3221 environment. Let 'ca' get its config file name from the environment
3222 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req'
3223 and 'x509').
3224 [Steve Henson]
3225
3226 *) Allow certificate policies extension to use an IA5STRING for the
3227 organization field. This is contrary to the PKIX definition but
3228 VeriSign uses it and IE5 only recognises this form. Document 'x509'
3229 extension option.
3230 [Steve Henson]
3231
3232 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic,
3233 without disallowing inline assembler and the like for non-pedantic builds.
3234 [Ben Laurie]
3235
3236 *) Support Borland C++ builder.
3237 [Janez Jere <jj@void.si>, modified by Ulf M�ller]
3238
3239 *) Support Mingw32.
3240 [Ulf M�ller]
3241
3242 *) SHA-1 cleanups and performance enhancements.
3243 [Andy Polyakov <appro@fy.chalmers.se>]
3244
3245 *) Sparc v8plus assembler for the bignum library.
3246 [Andy Polyakov <appro@fy.chalmers.se>]
3247
3248 *) Accept any -xxx and +xxx compiler options in Configure.
3249 [Ulf M�ller]
3250
3251 *) Update HPUX configuration.
3252 [Anonymous]
3253
3254 *) Add missing sk_<type>_unshift() function to safestack.h
3255 [Ralf S. Engelschall]
3256
3257 *) New function SSL_CTX_use_certificate_chain_file that sets the
3258 "extra_cert"s in addition to the certificate. (This makes sense
3259 only for "PEM" format files, as chains as a whole are not
3260 DER-encoded.)
3261 [Bodo Moeller]
3262
3263 *) Support verify_depth from the SSL API.
3264 x509_vfy.c had what can be considered an off-by-one-error:
3265 Its depth (which was not part of the external interface)
3266 was actually counting the number of certificates in a chain;
3267 now it really counts the depth.
3268 [Bodo Moeller]
3269
3270 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used
3271 instead of X509err, which often resulted in confusing error
3272 messages since the error codes are not globally unique
3273 (e.g. an alleged error in ssl3_accept when a certificate
3274 didn't match the private key).
3275
3276 *) New function SSL_CTX_set_session_id_context that allows to set a default
3277 value (so that you don't need SSL_set_session_id_context for each
3278 connection using the SSL_CTX).
3279 [Bodo Moeller]
3280
3281 *) OAEP decoding bug fix.
3282 [Ulf M�ller]
3283
3284 *) Support INSTALL_PREFIX for package builders, as proposed by
3285 David Harris.
3286 [Bodo Moeller]
3287
3288 *) New Configure options "threads" and "no-threads". For systems
3289 where the proper compiler options are known (currently Solaris
3290 and Linux), "threads" is the default.
3291 [Bodo Moeller]
3292
3293 *) New script util/mklink.pl as a faster substitute for util/mklink.sh.
3294 [Bodo Moeller]
3295
3296 *) Install various scripts to $(OPENSSLDIR)/misc, not to
3297 $(INSTALLTOP)/bin -- they shouldn't clutter directories
3298 such as /usr/local/bin.
3299 [Bodo Moeller]
3300
3301 *) "make linux-shared" to build shared libraries.
3302 [Niels Poppe <niels@netbox.org>]
3303
3304 *) New Configure option no-<cipher> (rsa, idea, rc5, ...).
3305 [Ulf M�ller]
3306
3307 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for
3308 extension adding in x509 utility.
3309 [Steve Henson]
3310
3311 *) Remove NOPROTO sections and error code comments.
3312 [Ulf M�ller]
3313
3314 *) Partial rewrite of the DEF file generator to now parse the ANSI
3315 prototypes.
3316 [Steve Henson]
3317
3318 *) New Configure options --prefix=DIR and --openssldir=DIR.
3319 [Ulf M�ller]
3320
3321 *) Complete rewrite of the error code script(s). It is all now handled
3322 by one script at the top level which handles error code gathering,
3323 header rewriting and C source file generation. It should be much better
3324 than the old method: it now uses a modified version of Ulf's parser to
3325 read the ANSI prototypes in all header files (thus the old K&R definitions
3326 aren't needed for error creation any more) and do a better job of
3327 translating function codes into names. The old 'ASN1 error code imbedded
3328 in a comment' is no longer necessary and it doesn't use .err files which
3329 have now been deleted. Also the error code call doesn't have to appear all
3330 on one line (which resulted in some large lines...).
3331 [Steve Henson]
3332
3333 *) Change #include filenames from <foo.h> to <openssl/foo.h>.
3334 [Bodo Moeller]
3335
3336 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return
3337 0 (which usually indicates a closed connection), but continue reading.
3338 [Bodo Moeller]
3339
3340 *) Fix some race conditions.
3341 [Bodo Moeller]
3342
3343 *) Add support for CRL distribution points extension. Add Certificate
3344 Policies and CRL distribution points documentation.
3345 [Steve Henson]
3346
3347 *) Move the autogenerated header file parts to crypto/opensslconf.h.
3348 [Ulf M�ller]
3349
3350 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of
3351 8 of keying material. Merlin has also confirmed interop with this fix
3352 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0.
3353 [Merlin Hughes <merlin@baltimore.ie>]
3354
3355 *) Fix lots of warnings.
3356 [Richard Levitte <levitte@stacken.kth.se>]
3357
3358 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if
3359 the directory spec didn't end with a LIST_SEPARATOR_CHAR.
3360 [Richard Levitte <levitte@stacken.kth.se>]
3361
3362 *) Fix problems with sizeof(long) == 8.
3363 [Andy Polyakov <appro@fy.chalmers.se>]
3364
3365 *) Change functions to ANSI C.
3366 [Ulf M�ller]
3367
3368 *) Fix typos in error codes.
3369 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf M�ller]
3370
3371 *) Remove defunct assembler files from Configure.
3372 [Ulf M�ller]
3373
3374 *) SPARC v8 assembler BIGNUM implementation.
3375 [Andy Polyakov <appro@fy.chalmers.se>]
3376
3377 *) Support for Certificate Policies extension: both print and set.
3378 Various additions to support the r2i method this uses.
3379 [Steve Henson]
3380
3381 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could
3382 return a const string when you are expecting an allocated buffer.
3383 [Ben Laurie]
3384
3385 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE
3386 types DirectoryString and DisplayText.
3387 [Steve Henson]
3388
3389 *) Add code to allow r2i extensions to access the configuration database,
3390 add an LHASH database driver and add several ctx helper functions.
3391 [Steve Henson]
3392
3393 *) Fix an evil bug in bn_expand2() which caused various BN functions to
3394 fail when they extended the size of a BIGNUM.
3395 [Steve Henson]
3396
3397 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to
3398 support typesafe stack.
3399 [Steve Henson]
3400
3401 *) Fix typo in SSL_[gs]et_options().
3402 [Nils Frostberg <nils@medcom.se>]
3403
3404 *) Delete various functions and files that belonged to the (now obsolete)
3405 old X509V3 handling code.
3406 [Steve Henson]
3407
3408 *) New Configure option "rsaref".
3409 [Ulf M�ller]
3410
3411 *) Don't auto-generate pem.h.
3412 [Bodo Moeller]
3413
3414 *) Introduce type-safe ASN.1 SETs.
3415 [Ben Laurie]
3416
3417 *) Convert various additional casted stacks to type-safe STACK_OF() variants.
3418 [Ben Laurie, Ralf S. Engelschall, Steve Henson]
3419
3420 *) Introduce type-safe STACKs. This will almost certainly break lots of code
3421 that links with OpenSSL (well at least cause lots of warnings), but fear
3422 not: the conversion is trivial, and it eliminates loads of evil casts. A
3423 few STACKed things have been converted already. Feel free to convert more.
3424 In the fullness of time, I'll do away with the STACK type altogether.
3425 [Ben Laurie]
3426
3427 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate
3428 specified in <certfile> by updating the entry in the index.txt file.
3429 This way one no longer has to edit the index.txt file manually for
3430 revoking a certificate. The -revoke option does the gory details now.
3431 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall]
3432
3433 *) Fix `openssl crl -noout -text' combination where `-noout' killed the
3434 `-text' option at all and this way the `-noout -text' combination was
3435 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'.
3436 [Ralf S. Engelschall]
3437
3438 *) Make sure a corresponding plain text error message exists for the
3439 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a
3440 verify callback function determined that a certificate was revoked.
3441 [Ralf S. Engelschall]
3442
3443 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for
3444 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test
3445 all available cipers including rc5, which was forgotten until now.
3446 In order to let the testing shell script know which algorithms
3447 are available, a new (up to now undocumented) command
3448 "openssl list-cipher-commands" is used.
3449 [Bodo Moeller]
3450
3451 *) Bugfix: s_client occasionally would sleep in select() when
3452 it should have checked SSL_pending() first.
3453 [Bodo Moeller]
3454
3455 *) New functions DSA_do_sign and DSA_do_verify to provide access to
3456 the raw DSA values prior to ASN.1 encoding.
3457 [Ulf M�ller]
3458
3459 *) Tweaks to Configure
3460 [Niels Poppe <niels@netbox.org>]
3461
3462 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support,
3463 yet...
3464 [Steve Henson]
3465
3466 *) New variables $(RANLIB) and $(PERL) in the Makefiles.
3467 [Ulf M�ller]
3468
3469 *) New config option to avoid instructions that are illegal on the 80386.
3470 The default code is faster, but requires at least a 486.
3471 [Ulf M�ller]
3472
3473 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
3474 SSL2_SERVER_VERSION (not used at all) macros, which are now the
3475 same as SSL2_VERSION anyway.
3476 [Bodo Moeller]
3477
3478 *) New "-showcerts" option for s_client.
3479 [Bodo Moeller]
3480
3481 *) Still more PKCS#12 integration. Add pkcs12 application to openssl
3482 application. Various cleanups and fixes.
3483 [Steve Henson]
3484
3485 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and
3486 modify error routines to work internally. Add error codes and PBE init
3487 to library startup routines.
3488 [Steve Henson]
3489
3490 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and
3491 packing functions to asn1 and evp. Changed function names and error
3492 codes along the way.
3493 [Steve Henson]
3494
3495 *) PKCS12 integration: and so it begins... First of several patches to
3496 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12
3497 objects to objects.h
3498 [Steve Henson]
3499
3500 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1
3501 and display support for Thawte strong extranet extension.
3502 [Steve Henson]
3503
3504 *) Add LinuxPPC support.
3505 [Jeff Dubrule <igor@pobox.org>]
3506
3507 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to
3508 bn_div_words in alpha.s.
3509 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie]
3510
3511 *) Make sure the RSA OAEP test is skipped under -DRSAref because
3512 OAEP isn't supported when OpenSSL is built with RSAref.
3513 [Ulf Moeller <ulf@fitug.de>]
3514
3515 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h
3516 so they no longer are missing under -DNOPROTO.
3517 [Soren S. Jorvang <soren@t.dk>]
3518
3519
3520 Changes between 0.9.1c and 0.9.2b [22 Mar 1999]
3521
3522 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still
3523 doesn't work when the session is reused. Coming soon!
3524 [Ben Laurie]
3525
3526 *) Fix a security hole, that allows sessions to be reused in the wrong
3527 context thus bypassing client cert protection! All software that uses
3528 client certs and session caches in multiple contexts NEEDS PATCHING to
3529 allow session reuse! A fuller solution is in the works.
3530 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)]
3531
3532 *) Some more source tree cleanups (removed obsolete files
3533 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed
3534 permission on "config" script to be executable) and a fix for the INSTALL
3535 document.
3536 [Ulf Moeller <ulf@fitug.de>]
3537
3538 *) Remove some legacy and erroneous uses of malloc, free instead of
3539 Malloc, Free.
3540 [Lennart Bang <lob@netstream.se>, with minor changes by Steve]
3541
3542 *) Make rsa_oaep_test return non-zero on error.
3543 [Ulf Moeller <ulf@fitug.de>]
3544
3545 *) Add support for native Solaris shared libraries. Configure
3546 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice
3547 if someone would make that last step automatic.
3548 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>]
3549
3550 *) ctx_size was not built with the right compiler during "make links". Fixed.
3551 [Ben Laurie]
3552
3553 *) Change the meaning of 'ALL' in the cipher list. It now means "everything
3554 except NULL ciphers". This means the default cipher list will no longer
3555 enable NULL ciphers. They need to be specifically enabled e.g. with
3556 the string "DEFAULT:eNULL".
3557 [Steve Henson]
3558
3559 *) Fix to RSA private encryption routines: if p < q then it would
3560 occasionally produce an invalid result. This will only happen with
3561 externally generated keys because OpenSSL (and SSLeay) ensure p > q.
3562 [Steve Henson]
3563
3564 *) Be less restrictive and allow also `perl util/perlpath.pl
3565 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin',
3566 because this way one can also use an interpreter named `perl5' (which is
3567 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still
3568 installed as `perl').
3569 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3570
3571 *) Let util/clean-depend.pl work also with older Perl 5.00x versions.
3572 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3573
3574 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add
3575 advapi32.lib to Win32 build and change the pem test comparision
3576 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the
3577 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h
3578 and crypto/des/ede_cbcm_enc.c.
3579 [Steve Henson]
3580
3581 *) DES quad checksum was broken on big-endian architectures. Fixed.
3582 [Ben Laurie]
3583
3584 *) Comment out two functions in bio.h that aren't implemented. Fix up the
3585 Win32 test batch file so it (might) work again. The Win32 test batch file
3586 is horrible: I feel ill....
3587 [Steve Henson]
3588
3589 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected
3590 in e_os.h. Audit of header files to check ANSI and non ANSI
3591 sections: 10 functions were absent from non ANSI section and not exported
3592 from Windows DLLs. Fixed up libeay.num for new functions.
3593 [Steve Henson]
3594
3595 *) Make `openssl version' output lines consistent.
3596 [Ralf S. Engelschall]
3597
3598 *) Fix Win32 symbol export lists for BIO functions: Added
3599 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data
3600 to ms/libeay{16,32}.def.
3601 [Ralf S. Engelschall]
3602
3603 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled
3604 fine under Unix and passes some trivial tests I've now added. But the
3605 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was
3606 added to make sure no one expects that this stuff really works in the
3607 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources
3608 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and
3609 openssl_bio.xs.
3610 [Ralf S. Engelschall]
3611
3612 *) Fix the generation of two part addresses in perl.
3613 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie]
3614
3615 *) Add config entry for Linux on MIPS.
3616 [John Tobey <jtobey@channel1.com>]
3617
3618 *) Make links whenever Configure is run, unless we are on Windoze.
3619 [Ben Laurie]
3620
3621 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf.
3622 Currently only issuerAltName and AuthorityKeyIdentifier make any sense
3623 in CRLs.
3624 [Steve Henson]
3625
3626 *) Add a useful kludge to allow package maintainers to specify compiler and
3627 other platforms details on the command line without having to patch the
3628 Configure script everytime: One now can use ``perl Configure
3629 <id>:<details>'', i.e. platform ids are allowed to have details appended
3630 to them (seperated by colons). This is treated as there would be a static
3631 pre-configured entry in Configure's %table under key <id> with value
3632 <details> and ``perl Configure <id>'' is called. So, when you want to
3633 perform a quick test-compile under FreeBSD 3.1 with pgcc and without
3634 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"''
3635 now, which overrides the FreeBSD-elf entry on-the-fly.
3636 [Ralf S. Engelschall]
3637
3638 *) Disable new TLS1 ciphersuites by default: they aren't official yet.
3639 [Ben Laurie]
3640
3641 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified
3642 on the `perl Configure ...' command line. This way one can compile
3643 OpenSSL libraries with Position Independent Code (PIC) which is needed
3644 for linking it into DSOs.
3645 [Ralf S. Engelschall]
3646
3647 *) Remarkably, export ciphers were totally broken and no-one had noticed!
3648 Fixed.
3649 [Ben Laurie]
3650
3651 *) Cleaned up the LICENSE document: The official contact for any license
3652 questions now is the OpenSSL core team under openssl-core@openssl.org.
3653 And add a paragraph about the dual-license situation to make sure people
3654 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply
3655 to the OpenSSL toolkit.
3656 [Ralf S. Engelschall]
3657
3658 *) General source tree makefile cleanups: Made `making xxx in yyy...'
3659 display consistent in the source tree and replaced `/bin/rm' by `rm'.
3660 Additonally cleaned up the `make links' target: Remove unnecessary
3661 semicolons, subsequent redundant removes, inline point.sh into mklink.sh
3662 to speed processing and no longer clutter the display with confusing
3663 stuff. Instead only the actually done links are displayed.
3664 [Ralf S. Engelschall]
3665
3666 *) Permit null encryption ciphersuites, used for authentication only. It used
3667 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this.
3668 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null
3669 encryption.
3670 [Ben Laurie]
3671
3672 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder
3673 signed attributes when verifying signatures (this would break them),
3674 the detached data encoding was wrong and public keys obtained using
3675 X509_get_pubkey() weren't freed.
3676 [Steve Henson]
3677
3678 *) Add text documentation for the BUFFER functions. Also added a work around
3679 to a Win95 console bug. This was triggered by the password read stuff: the
3680 last character typed gets carried over to the next fread(). If you were
3681 generating a new cert request using 'req' for example then the last
3682 character of the passphrase would be CR which would then enter the first
3683 field as blank.
3684 [Steve Henson]
3685
3686 *) Added the new `Includes OpenSSL Cryptography Software' button as
3687 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay
3688 button and can be used by applications based on OpenSSL to show the
3689 relationship to the OpenSSL project.
3690 [Ralf S. Engelschall]
3691
3692 *) Remove confusing variables in function signatures in files
3693 ssl/ssl_lib.c and ssl/ssl.h.
3694 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3695
3696 *) Don't install bss_file.c under PREFIX/include/
3697 [Lennart Bong <lob@kulthea.stacken.kth.se>]
3698
3699 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle
3700 functions that return function pointers and has support for NT specific
3701 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various
3702 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from
3703 unsigned to signed types: this was killing the Win32 compile.
3704 [Steve Henson]
3705
3706 *) Add new certificate file to stack functions,
3707 SSL_add_dir_cert_subjects_to_stack() and
3708 SSL_add_file_cert_subjects_to_stack(). These largely supplant
3709 SSL_load_client_CA_file(), and can be used to add multiple certs easily
3710 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()).
3711 This means that Apache-SSL and similar packages don't have to mess around
3712 to add as many CAs as they want to the preferred list.
3713 [Ben Laurie]
3714
3715 *) Experiment with doxygen documentation. Currently only partially applied to
3716 ssl/ssl_lib.c.
3717 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with
3718 openssl.doxy as the configuration file.
3719 [Ben Laurie]
3720
3721 *) Get rid of remaining C++-style comments which strict C compilers hate.
3722 [Ralf S. Engelschall, pointed out by Carlos Amengual]
3723
3724 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not
3725 compiled in by default: it has problems with large keys.
3726 [Steve Henson]
3727
3728 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and
3729 DH private keys and/or callback functions which directly correspond to
3730 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This
3731 is needed for applications which have to configure certificates on a
3732 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis
3733 (e.g. s_server).
3734 For the RSA certificate situation is makes no difference, but
3735 for the DSA certificate situation this fixes the "no shared cipher"
3736 problem where the OpenSSL cipher selection procedure failed because the
3737 temporary keys were not overtaken from the context and the API provided
3738 no way to reconfigure them.
3739 The new functions now let applications reconfigure the stuff and they
3740 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh,
3741 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new
3742 non-public-API function ssl_cert_instantiate() is used as a helper
3743 function and also to reduce code redundancy inside ssl_rsa.c.
3744 [Ralf S. Engelschall]
3745
3746 *) Move s_server -dcert and -dkey options out of the undocumented feature
3747 area because they are useful for the DSA situation and should be
3748 recognized by the users.
3749 [Ralf S. Engelschall]
3750
3751 *) Fix the cipher decision scheme for export ciphers: the export bits are
3752 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within
3753 SSL_EXP_MASK. So, the original variable has to be used instead of the
3754 already masked variable.
3755 [Richard Levitte <levitte@stacken.kth.se>]
3756
3757 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c
3758 [Richard Levitte <levitte@stacken.kth.se>]
3759
3760 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal()
3761 from `int' to `unsigned int' because it's a length and initialized by
3762 EVP_DigestFinal() which expects an `unsigned int *'.
3763 [Richard Levitte <levitte@stacken.kth.se>]
3764
3765 *) Don't hard-code path to Perl interpreter on shebang line of Configure
3766 script. Instead use the usual Shell->Perl transition trick.
3767 [Ralf S. Engelschall]
3768
3769 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates
3770 (in addition to RSA certificates) to match the behaviour of `openssl dsa
3771 -noout -modulus' as it's already the case for `openssl rsa -noout
3772 -modulus'. For RSA the -modulus is the real "modulus" while for DSA
3773 currently the public key is printed (a decision which was already done by
3774 `openssl dsa -modulus' in the past) which serves a similar purpose.
3775 Additionally the NO_RSA no longer completely removes the whole -modulus
3776 option; it now only avoids using the RSA stuff. Same applies to NO_DSA
3777 now, too.
3778 [Ralf S. Engelschall]
3779
3780 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested
3781 BIO. See the source (crypto/evp/bio_ok.c) for more info.
3782 [Arne Ansper <arne@ats.cyber.ee>]
3783
3784 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs
3785 to be added. Now both 'req' and 'ca' can use new objects defined in the
3786 config file.
3787 [Steve Henson]
3788
3789 *) Add cool BIO that does syslog (or event log on NT).
3790 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie]
3791
3792 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5,
3793 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and
3794 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher
3795 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt.
3796 [Ben Laurie]
3797
3798 *) Add preliminary config info for new extension code.
3799 [Steve Henson]
3800
3801 *) Make RSA_NO_PADDING really use no padding.
3802 [Ulf Moeller <ulf@fitug.de>]
3803
3804 *) Generate errors when private/public key check is done.
3805 [Ben Laurie]
3806
3807 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support
3808 for some CRL extensions and new objects added.
3809 [Steve Henson]
3810
3811 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private
3812 key usage extension and fuller support for authority key id.
3813 [Steve Henson]
3814
3815 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved
3816 padding method for RSA, which is recommended for new applications in PKCS
3817 #1 v2.0 (RFC 2437, October 1998).
3818 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical
3819 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure
3820 against Bleichbacher's attack on RSA.
3821 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by
3822 Ben Laurie]
3823
3824 *) Updates to the new SSL compression code
3825 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3826
3827 *) Fix so that the version number in the master secret, when passed
3828 via RSA, checks that if TLS was proposed, but we roll back to SSLv3
3829 (because the server will not accept higher), that the version number
3830 is 0x03,0x01, not 0x03,0x00
3831 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3832
3833 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory
3834 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes
3835 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c
3836 [Steve Henson]
3837
3838 *) Support for RAW extensions where an arbitrary extension can be
3839 created by including its DER encoding. See apps/openssl.cnf for
3840 an example.
3841 [Steve Henson]
3842
3843 *) Make sure latest Perl versions don't interpret some generated C array
3844 code as Perl array code in the crypto/err/err_genc.pl script.
3845 [Lars Weber <3weber@informatik.uni-hamburg.de>]
3846
3847 *) Modify ms/do_ms.bat to not generate assembly language makefiles since
3848 not many people have the assembler. Various Win32 compilation fixes and
3849 update to the INSTALL.W32 file with (hopefully) more accurate Win32
3850 build instructions.
3851 [Steve Henson]
3852
3853 *) Modify configure script 'Configure' to automatically create crypto/date.h
3854 file under Win32 and also build pem.h from pem.org. New script
3855 util/mkfiles.pl to create the MINFO file on environments that can't do a
3856 'make files': perl util/mkfiles.pl >MINFO should work.
3857 [Steve Henson]
3858
3859 *) Major rework of DES function declarations, in the pursuit of correctness
3860 and purity. As a result, many evil casts evaporated, and some weirdness,
3861 too. You may find this causes warnings in your code. Zapping your evil
3862 casts will probably fix them. Mostly.
3863 [Ben Laurie]
3864
3865 *) Fix for a typo in asn1.h. Bug fix to object creation script
3866 obj_dat.pl. It considered a zero in an object definition to mean
3867 "end of object": none of the objects in objects.h have any zeros
3868 so it wasn't spotted.
3869 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>]
3870
3871 *) Add support for Triple DES Cipher Block Chaining with Output Feedback
3872 Masking (CBCM). In the absence of test vectors, the best I have been able
3873 to do is check that the decrypt undoes the encrypt, so far. Send me test
3874 vectors if you have them.
3875 [Ben Laurie]
3876
3877 *) Correct calculation of key length for export ciphers (too much space was
3878 allocated for null ciphers). This has not been tested!
3879 [Ben Laurie]
3880
3881 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage
3882 message is now correct (it understands "crypto" and "ssl" on its
3883 command line). There is also now an "update" option. This will update
3884 the util/ssleay.num and util/libeay.num files with any new functions.
3885 If you do a:
3886 perl util/mkdef.pl crypto ssl update
3887 it will update them.
3888 [Steve Henson]
3889
3890 *) Overhauled the Perl interface (perl/*):
3891 - ported BN stuff to OpenSSL's different BN library
3892 - made the perl/ source tree CVS-aware
3893 - renamed the package from SSLeay to OpenSSL (the files still contain
3894 their history because I've copied them in the repository)
3895 - removed obsolete files (the test scripts will be replaced
3896 by better Test::Harness variants in the future)
3897 [Ralf S. Engelschall]
3898
3899 *) First cut for a very conservative source tree cleanup:
3900 1. merge various obsolete readme texts into doc/ssleay.txt
3901 where we collect the old documents and readme texts.
3902 2. remove the first part of files where I'm already sure that we no
3903 longer need them because of three reasons: either they are just temporary
3904 files which were left by Eric or they are preserved original files where
3905 I've verified that the diff is also available in the CVS via "cvs diff
3906 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for
3907 the crypto/md/ stuff).
3908 [Ralf S. Engelschall]
3909
3910 *) More extension code. Incomplete support for subject and issuer alt
3911 name, issuer and authority key id. Change the i2v function parameters
3912 and add an extra 'crl' parameter in the X509V3_CTX structure: guess
3913 what that's for :-) Fix to ASN1 macro which messed up
3914 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED.
3915 [Steve Henson]
3916
3917 *) Preliminary support for ENUMERATED type. This is largely copied from the
3918 INTEGER code.
3919 [Steve Henson]
3920
3921 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy.
3922 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3923
3924 *) Make sure `make rehash' target really finds the `openssl' program.
3925 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>]
3926
3927 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd
3928 like to hear about it if this slows down other processors.
3929 [Ben Laurie]
3930
3931 *) Add CygWin32 platform information to Configure script.
3932 [Alan Batie <batie@aahz.jf.intel.com>]
3933
3934 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm'
3935 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>]
3936
3937 *) New program nseq to manipulate netscape certificate sequences
3938 [Steve Henson]
3939
3940 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a
3941 few typos.
3942 [Steve Henson]
3943
3944 *) Fixes to BN code. Previously the default was to define BN_RECURSION
3945 but the BN code had some problems that would cause failures when
3946 doing certificate verification and some other functions.
3947 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)]
3948
3949 *) Add ASN1 and PEM code to support netscape certificate sequences.
3950 [Steve Henson]
3951
3952 *) Add ASN1 and PEM code to support netscape certificate sequences.
3953 [Steve Henson]
3954
3955 *) Add several PKIX and private extended key usage OIDs.
3956 [Steve Henson]
3957
3958 *) Modify the 'ca' program to handle the new extension code. Modify
3959 openssl.cnf for new extension format, add comments.
3960 [Steve Henson]
3961
3962 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req'
3963 and add a sample to openssl.cnf so req -x509 now adds appropriate
3964 CA extensions.
3965 [Steve Henson]
3966
3967 *) Continued X509 V3 changes. Add to other makefiles, integrate with the
3968 error code, add initial support to X509_print() and x509 application.
3969 [Steve Henson]
3970
3971 *) Takes a deep breath and start addding X509 V3 extension support code. Add
3972 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this
3973 stuff is currently isolated and isn't even compiled yet.
3974 [Steve Henson]
3975
3976 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL
3977 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print.
3978 Removed the versions check from X509 routines when loading extensions:
3979 this allows certain broken certificates that don't set the version
3980 properly to be processed.
3981 [Steve Henson]
3982
3983 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another
3984 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which
3985 can still be regenerated with "make depend".
3986 [Ben Laurie]
3987
3988 *) Spelling mistake in C version of CAST-128.
3989 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>]
3990
3991 *) Changes to the error generation code. The perl script err-code.pl
3992 now reads in the old error codes and retains the old numbers, only
3993 adding new ones if necessary. It also only changes the .err files if new
3994 codes are added. The makefiles have been modified to only insert errors
3995 when needed (to avoid needlessly modifying header files). This is done
3996 by only inserting errors if the .err file is newer than the auto generated
3997 C file. To rebuild all the error codes from scratch (the old behaviour)
3998 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl
3999 or delete all the .err files.
4000 [Steve Henson]
4001
4002 *) CAST-128 was incorrectly implemented for short keys. The C version has
4003 been fixed, but is untested. The assembler versions are also fixed, but
4004 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing
4005 to regenerate it if needed.
4006 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun
4007 Hagino <itojun@kame.net>]
4008
4009 *) File was opened incorrectly in randfile.c.
4010 [Ulf M�ller <ulf@fitug.de>]
4011
4012 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print
4013 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or
4014 GeneralizedTime. ASN1_TIME is the proper type used in certificates et
4015 al: it's just almost always a UTCTime. Note this patch adds new error
4016 codes so do a "make errors" if there are problems.
4017 [Steve Henson]
4018
4019 *) Correct Linux 1 recognition in config.
4020 [Ulf M�ller <ulf@fitug.de>]
4021
4022 *) Remove pointless MD5 hash when using DSA keys in ca.
4023 [Anonymous <nobody@replay.com>]
4024
4025 *) Generate an error if given an empty string as a cert directory. Also
4026 generate an error if handed NULL (previously returned 0 to indicate an
4027 error, but didn't set one).
4028 [Ben Laurie, reported by Anonymous <nobody@replay.com>]
4029
4030 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last.
4031 [Ben Laurie]
4032
4033 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct
4034 parameters. This was causing a warning which killed off the Win32 compile.
4035 [Steve Henson]
4036
4037 *) Remove C++ style comments from crypto/bn/bn_local.h.
4038 [Neil Costigan <neil.costigan@celocom.com>]
4039
4040 *) The function OBJ_txt2nid was broken. It was supposed to return a nid
4041 based on a text string, looking up short and long names and finally
4042 "dot" format. The "dot" format stuff didn't work. Added new function
4043 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote
4044 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the
4045 OID is not part of the table.
4046 [Steve Henson]
4047
4048 *) Add prototypes to X509 lookup/verify methods, fixing a bug in
4049 X509_LOOKUP_by_alias().
4050 [Ben Laurie]
4051
4052 *) Sort openssl functions by name.
4053 [Ben Laurie]
4054
4055 *) Get the gendsa program working (hopefully) and add it to app list. Remove
4056 encryption from sample DSA keys (in case anyone is interested the password
4057 was "1234").
4058 [Steve Henson]
4059
4060 *) Make _all_ *_free functions accept a NULL pointer.
4061 [Frans Heymans <fheymans@isaserver.be>]
4062
4063 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use
4064 NULL pointers.
4065 [Anonymous <nobody@replay.com>]
4066
4067 *) s_server should send the CAfile as acceptable CAs, not its own cert.
4068 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4069
4070 *) Don't blow it for numeric -newkey arguments to apps/req.
4071 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>]
4072
4073 *) Temp key "for export" tests were wrong in s3_srvr.c.
4074 [Anonymous <nobody@replay.com>]
4075
4076 *) Add prototype for temp key callback functions
4077 SSL_CTX_set_tmp_{rsa,dh}_callback().
4078 [Ben Laurie]
4079
4080 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and
4081 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey().
4082 [Steve Henson]
4083
4084 *) X509_name_add_entry() freed the wrong thing after an error.
4085 [Arne Ansper <arne@ats.cyber.ee>]
4086
4087 *) rsa_eay.c would attempt to free a NULL context.
4088 [Arne Ansper <arne@ats.cyber.ee>]
4089
4090 *) BIO_s_socket() had a broken should_retry() on Windoze.
4091 [Arne Ansper <arne@ats.cyber.ee>]
4092
4093 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH.
4094 [Arne Ansper <arne@ats.cyber.ee>]
4095
4096 *) Make sure the already existing X509_STORE->depth variable is initialized
4097 in X509_STORE_new(), but document the fact that this variable is still
4098 unused in the certificate verification process.
4099 [Ralf S. Engelschall]
4100
4101 *) Fix the various library and apps files to free up pkeys obtained from
4102 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions.
4103 [Steve Henson]
4104
4105 *) Fix reference counting in X509_PUBKEY_get(). This makes
4106 demos/maurice/example2.c work, amongst others, probably.
4107 [Steve Henson and Ben Laurie]
4108
4109 *) First cut of a cleanup for apps/. First the `ssleay' program is now named
4110 `openssl' and second, the shortcut symlinks for the `openssl <command>'
4111 are no longer created. This way we have a single and consistent command
4112 line interface `openssl <command>', similar to `cvs <command>'.
4113 [Ralf S. Engelschall, Paul Sutton and Ben Laurie]
4114
4115 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey
4116 BIT STRING wrapper always have zero unused bits.
4117 [Steve Henson]
4118
4119 *) Add CA.pl, perl version of CA.sh, add extended key usage OID.
4120 [Steve Henson]
4121
4122 *) Make the top-level INSTALL documentation easier to understand.
4123 [Paul Sutton]
4124
4125 *) Makefiles updated to exit if an error occurs in a sub-directory
4126 make (including if user presses ^C) [Paul Sutton]
4127
4128 *) Make Montgomery context stuff explicit in RSA data structure.
4129 [Ben Laurie]
4130
4131 *) Fix build order of pem and err to allow for generated pem.h.
4132 [Ben Laurie]
4133
4134 *) Fix renumbering bug in X509_NAME_delete_entry().
4135 [Ben Laurie]
4136
4137 *) Enhanced the err-ins.pl script so it makes the error library number
4138 global and can add a library name. This is needed for external ASN1 and
4139 other error libraries.
4140 [Steve Henson]
4141
4142 *) Fixed sk_insert which never worked properly.
4143 [Steve Henson]
4144
4145 *) Fix ASN1 macros so they can handle indefinite length construted
4146 EXPLICIT tags. Some non standard certificates use these: they can now
4147 be read in.
4148 [Steve Henson]
4149
4150 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc)
4151 into a single doc/ssleay.txt bundle. This way the information is still
4152 preserved but no longer messes up this directory. Now it's new room for
4153 the new set of documenation files.
4154 [Ralf S. Engelschall]
4155
4156 *) SETs were incorrectly DER encoded. This was a major pain, because they
4157 shared code with SEQUENCEs, which aren't coded the same. This means that
4158 almost everything to do with SETs or SEQUENCEs has either changed name or
4159 number of arguments.
4160 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>]
4161
4162 *) Fix test data to work with the above.
4163 [Ben Laurie]
4164
4165 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but
4166 was already fixed by Eric for 0.9.1 it seems.
4167 [Ben Laurie - pointed out by Ulf M�ller <ulf@fitug.de>]
4168
4169 *) Autodetect FreeBSD3.
4170 [Ben Laurie]
4171
4172 *) Fix various bugs in Configure. This affects the following platforms:
4173 nextstep
4174 ncr-scde
4175 unixware-2.0
4176 unixware-2.0-pentium
4177 sco5-cc.
4178 [Ben Laurie]
4179
4180 *) Eliminate generated files from CVS. Reorder tests to regenerate files
4181 before they are needed.
4182 [Ben Laurie]
4183
4184 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy).
4185 [Ben Laurie]
4186
4187
4188 Changes between 0.9.1b and 0.9.1c [23-Dec-1998]
4189
4190 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and
4191 changed SSLeay to OpenSSL in version strings.
4192 [Ralf S. Engelschall]
4193
4194 *) Some fixups to the top-level documents.
4195 [Paul Sutton]
4196
4197 *) Fixed the nasty bug where rsaref.h was not found under compile-time
4198 because the symlink to include/ was missing.
4199 [Ralf S. Engelschall]
4200
4201 *) Incorporated the popular no-RSA/DSA-only patches
4202 which allow to compile a RSA-free SSLeay.
4203 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall]
4204
4205 *) Fixed nasty rehash problem under `make -f Makefile.ssl links'
4206 when "ssleay" is still not found.
4207 [Ralf S. Engelschall]
4208
4209 *) Added more platforms to Configure: Cray T3E, HPUX 11,
4210 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>]
4211
4212 *) Updated the README file.
4213 [Ralf S. Engelschall]
4214
4215 *) Added various .cvsignore files in the CVS repository subdirs
4216 to make a "cvs update" really silent.
4217 [Ralf S. Engelschall]
4218
4219 *) Recompiled the error-definition header files and added
4220 missing symbols to the Win32 linker tables.
4221 [Ralf S. Engelschall]
4222
4223 *) Cleaned up the top-level documents;
4224 o new files: CHANGES and LICENSE
4225 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay
4226 o merged COPYRIGHT into LICENSE
4227 o removed obsolete TODO file
4228 o renamed MICROSOFT to INSTALL.W32
4229 [Ralf S. Engelschall]
4230
4231 *) Removed dummy files from the 0.9.1b source tree:
4232 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi
4233 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f
4234 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f
4235 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f
4236 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f
4237 [Ralf S. Engelschall]
4238
4239 *) Added various platform portability fixes.
4240 [Mark J. Cox]
4241
4242 *) The Genesis of the OpenSSL rpject:
4243 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A.
4244 Young and Tim J. Hudson created while they were working for C2Net until
4245 summer 1998.
4246 [The OpenSSL Project]
4247
4248
4249 Changes between 0.9.0b and 0.9.1b [not released]
4250
4251 *) Updated a few CA certificates under certs/
4252 [Eric A. Young]
4253
4254 *) Changed some BIGNUM api stuff.
4255 [Eric A. Young]
4256
4257 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD,
4258 DGUX x86, Linux Alpha, etc.
4259 [Eric A. Young]
4260
4261 *) New COMP library [crypto/comp/] for SSL Record Layer Compression:
4262 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is
4263 available).
4264 [Eric A. Young]
4265
4266 *) Add -strparse option to asn1pars program which parses nested
4267 binary structures
4268 [Dr Stephen Henson <shenson@bigfoot.com>]
4269
4270 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs.
4271 [Eric A. Young]
4272
4273 *) DSA fix for "ca" program.
4274 [Eric A. Young]
4275
4276 *) Added "-genkey" option to "dsaparam" program.
4277 [Eric A. Young]
4278
4279 *) Added RIPE MD160 (rmd160) message digest.
4280 [Eric A. Young]
4281
4282 *) Added -a (all) option to "ssleay version" command.
4283 [Eric A. Young]
4284
4285 *) Added PLATFORM define which is the id given to Configure.
4286 [Eric A. Young]
4287
4288 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking.
4289 [Eric A. Young]
4290
4291 *) Extended the ASN.1 parser routines.
4292 [Eric A. Young]
4293
4294 *) Extended BIO routines to support REUSEADDR, seek, tell, etc.
4295 [Eric A. Young]
4296
4297 *) Added a BN_CTX to the BN library.
4298 [Eric A. Young]
4299
4300 *) Fixed the weak key values in DES library
4301 [Eric A. Young]
4302
4303 *) Changed API in EVP library for cipher aliases.
4304 [Eric A. Young]
4305
4306 *) Added support for RC2/64bit cipher.
4307 [Eric A. Young]
4308
4309 *) Converted the lhash library to the crypto/mem.c functions.
4310 [Eric A. Young]
4311
4312 *) Added more recognized ASN.1 object ids.
4313 [Eric A. Young]
4314
4315 *) Added more RSA padding checks for SSL/TLS.
4316 [Eric A. Young]
4317
4318 *) Added BIO proxy/filter functionality.
4319 [Eric A. Young]
4320
4321 *) Added extra_certs to SSL_CTX which can be used
4322 send extra CA certificates to the client in the CA cert chain sending
4323 process. It can be configured with SSL_CTX_add_extra_chain_cert().
4324 [Eric A. Young]
4325
4326 *) Now Fortezza is denied in the authentication phase because
4327 this is key exchange mechanism is not supported by SSLeay at all.
4328 [Eric A. Young]
4329
4330 *) Additional PKCS1 checks.
4331 [Eric A. Young]
4332
4333 *) Support the string "TLSv1" for all TLS v1 ciphers.
4334 [Eric A. Young]
4335
4336 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the
4337 ex_data index of the SSL context in the X509_STORE_CTX ex_data.
4338 [Eric A. Young]
4339
4340 *) Fixed a few memory leaks.
4341 [Eric A. Young]
4342
4343 *) Fixed various code and comment typos.
4344 [Eric A. Young]
4345
4346 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0
4347 bytes sent in the client random.
4348 [Edward Bishop <ebishop@spyglass.com>]
