1 2 OpenSSL CHANGES 3 _______________ 4 5 Changes between 0.9.3a and 0.9.4 [09 Aug 1999] 6 7 *) Install libRSAglue.a when OpenSSL is built with RSAref. 8 [Ralf S. Engelschall] 9 10 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. 11 [Andrija Antonijevic <TheAntony2@bigfoot.com>] 12 13 *) Fix -startdate and -enddate (which was missing) arguments to 'ca' 14 program. 15 [Steve Henson] 16 17 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as 18 DH parameters/keys (q is lost during that conversion, but the resulting 19 DH parameters contain its length). 20 21 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is 22 much faster than DH_generate_parameters (which creates parameters 23 where p = 2*q + 1), and also the smaller q makes DH computations 24 much more efficient (160-bit exponentiation instead of 1024-bit 25 exponentiation); so this provides a convenient way to support DHE 26 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of 27 utter importance to use 28 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); 29 or 30 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); 31 when such DH parameters are used, because otherwise small subgroup 32 attacks may become possible! 33 [Bodo Moeller] 34 35 *) Avoid memory leak in i2d_DHparams. 36 [Bodo Moeller] 37 38 *) Allow the -k option to be used more than once in the enc program: 39 this allows the same encrypted message to be read by multiple recipients. 40 [Steve Henson] 41 42 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts 43 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then 44 it will always use the numerical form of the OID, even if it has a short 45 or long name. 46 [Steve Henson] 47 48 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp 49 method only got called if p,q,dmp1,dmq1,iqmp components were present, 50 otherwise bn_mod_exp was called. In the case of hardware keys for example 51 no private key components need be present and it might store extra data 52 in the RSA structure, which cannot be accessed from bn_mod_exp. By setting 53 RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for private key 54 operations. 55 [Steve Henson] 56 57 *) Added support for SPARC Linux. 58 [Andy Polyakov] 59 60 *) pem_password_cb function type incompatibly changed from 61 typedef int pem_password_cb(char *buf, int size, int rwflag); 62 to 63 ....(char *buf, int size, int rwflag, void *userdata); 64 so that applications can pass data to their callbacks: 65 The PEM[_ASN1]_{read,write}... functions and macros now take an 66 additional void * argument, which is just handed through whenever 67 the password callback is called. 68 [Damien Miller <dmiller@ilogic.com.au>, with tiny changes by Bodo Moeller] 69 70 New function SSL_CTX_set_default_passwd_cb_userdata. 71 72 Compatibility note: As many C implementations push function arguments 73 onto the stack in reverse order, the new library version is likely to 74 interoperate with programs that have been compiled with the old 75 pem_password_cb definition (PEM_whatever takes some data that 76 happens to be on the stack as its last argument, and the callback 77 just ignores this garbage); but there is no guarantee whatsoever that 78 this will work. 79 80 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... 81 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused 82 problems not only on Windows, but also on some Unix platforms. 83 To avoid problematic command lines, these definitions are now in an 84 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl 85 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). 86 [Bodo Moeller] 87 88 *) MIPS III/IV assembler module is reimplemented. 89 [Andy Polyakov] 90 91 *) More DES library cleanups: remove references to srand/rand and 92 delete an unused file. 93 [Ulf M�ller] 94 95 *) Add support for the the free Netwide assembler (NASM) under Win32, 96 since not many people have MASM (ml) and it can be hard to obtain. 97 This is currently experimental but it seems to work OK and pass all 98 the tests. Check out INSTALL.W32 for info. 99 [Steve Henson] 100 101 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections 102 without temporary keys kept an extra copy of the server key, 103 and connections with temporary keys did not free everything in case 104 of an error. 105 [Bodo Moeller] 106 107 *) New function RSA_check_key and new openssl rsa option -check 108 for verifying the consistency of RSA keys. 109 [Ulf Moeller, Bodo Moeller] 110 111 *) Various changes to make Win32 compile work: 112 1. Casts to avoid "loss of data" warnings in p5_crpt2.c 113 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned 114 comparison" warnings. 115 3. Add sk_<TYPE>_sort to DEF file generator and do make update. 116 [Steve Henson] 117 118 *) Add a debugging option to PKCS#5 v2 key generation function: when 119 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and 120 derived keys are printed to stderr. 121 [Steve Henson] 122 123 *) Copy the flags in ASN1_STRING_dup(). 124 [Roman E. Pavlov <pre@mo.msk.ru>] 125 126 *) The x509 application mishandled signing requests containing DSA 127 keys when the signing key was also DSA and the parameters didn't match. 128 129 It was supposed to omit the parameters when they matched the signing key: 130 the verifying software was then supposed to automatically use the CA's 131 parameters if they were absent from the end user certificate. 132 133 Omitting parameters is no longer recommended. The test was also 134 the wrong way round! This was probably due to unusual behaviour in 135 EVP_cmp_parameters() which returns 1 if the parameters match. 136 This meant that parameters were omitted when they *didn't* match and 137 the certificate was useless. Certificates signed with 'ca' didn't have 138 this bug. 139 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>] 140 141 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. 142 The interface is as follows: 143 Applications can use 144 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), 145 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); 146 "off" is now the default. 147 The library internally uses 148 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), 149 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() 150 to disable memory-checking temporarily. 151 152 Some inconsistent states that previously were possible (and were 153 even the default) are now avoided. 154 155 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time 156 with each memory chunk allocated; this is occasionally more helpful 157 than just having a counter. 158 159 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. 160 161 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future 162 extensions. 163 [Bodo Moeller] 164 165 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), 166 which largely parallels "options", but is for changing API behaviour, 167 whereas "options" are about protocol behaviour. 168 Initial "mode" flags are: 169 170 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when 171 a single record has been written. 172 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write 173 retries use the same buffer location. 174 (But all of the contents must be 175 copied!) 176 [Bodo Moeller] 177 178 *) Bugfix: SSL_set_mode ignored its parameter, only SSL_CTX_set_mode 179 worked. 180 181 *) Fix problems with no-hmac etc. 182 [Ulf M�ller, pointed out by Brian Wellington <bwelling@tislabs.com>] 183 184 *) New functions RSA_get_default_method(), RSA_set_method() and 185 RSA_get_method(). These allows replacement of RSA_METHODs without having 186 to mess around with the internals of an RSA structure. 187 [Steve Henson] 188 189 *) Fix memory leaks in DSA_do_sign and DSA_is_prime. 190 Also really enable memory leak checks in openssl.c and in some 191 test programs. 192 [Chad C. Mulligan, Bodo Moeller] 193 194 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess 195 up the length of negative integers. This has now been simplified to just 196 store the length when it is first determined and use it later, rather 197 than trying to keep track of where data is copied and updating it to 198 point to the end. 199 [Steve Henson, reported by Brien Wheeler 200 <bwheeler@authentica-security.com>] 201 202 *) Add a new function PKCS7_signatureVerify. This allows the verification 203 of a PKCS#7 signature but with the signing certificate passed to the 204 function itself. This contrasts with PKCS7_dataVerify which assumes the 205 certificate is present in the PKCS#7 structure. This isn't always the 206 case: certificates can be omitted from a PKCS#7 structure and be 207 distributed by "out of band" means (such as a certificate database). 208 [Steve Henson] 209 210 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the 211 function prototypes in pem.h, also change util/mkdef.pl to add the 212 necessary function names. 213 [Steve Henson] 214 215 *) mk1mf.pl (used by Windows builds) did not properly read the 216 options set by Configure in the top level Makefile, and Configure 217 was not even able to write more than one option correctly. 218 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. 219 [Bodo Moeller] 220 221 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config 222 file to be loaded from a BIO or FILE pointer. The BIO version will 223 for example allow memory BIOs to contain config info. 224 [Steve Henson] 225 226 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. 227 Whoever hopes to achieve shared-library compatibility across versions 228 must use this, not the compile-time macro. 229 (Exercise 0.9.4: Which is the minimum library version required by 230 such programs?) 231 Note: All this applies only to multi-threaded programs, others don't 232 need locks. 233 [Bodo Moeller] 234 235 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests 236 through a BIO pair triggered the default case, i.e. 237 SSLerr(...,SSL_R_UNKNOWN_STATE). 238 [Bodo Moeller] 239 240 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications 241 can use the SSL library even if none of the specific BIOs is 242 appropriate. 243 [Bodo Moeller] 244 245 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value 246 for the encoded length. 247 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>] 248 249 *) Add initial documentation of the X509V3 functions. 250 [Steve Henson] 251 252 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and 253 PEM_write_bio_PKCS8PrivateKey() that are equivalent to 254 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more 255 secure PKCS#8 private key format with a high iteration count. 256 [Steve Henson] 257 258 *) Fix determination of Perl interpreter: A perl or perl5 259 _directory_ in $PATH was also accepted as the interpreter. 260 [Ralf S. Engelschall] 261 262 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking 263 wrong with it but it was very old and did things like calling 264 PEM_ASN1_read() directly and used MD5 for the hash not to mention some 265 unusual formatting. 266 [Steve Henson] 267 268 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed 269 to use the new extension code. 270 [Steve Henson] 271 272 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c 273 with macros. This should make it easier to change their form, add extra 274 arguments etc. Fix a few PEM prototypes which didn't have cipher as a 275 constant. 276 [Steve Henson] 277 278 *) Add to configuration table a new entry that can specify an alternative 279 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, 280 according to Mark Crispin <MRC@Panda.COM>. 281 [Bodo Moeller] 282 283#if 0 284 *) DES CBC did not update the IV. Weird. 285 [Ben Laurie] 286#else 287 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. 288 Changing the behaviour of the former might break existing programs -- 289 where IV updating is needed, des_ncbc_encrypt can be used. 290#endif 291 292 *) When bntest is run from "make test" it drives bc to check its 293 calculations, as well as internally checking them. If an internal check 294 fails, it needs to cause bc to give a non-zero result or make test carries 295 on without noticing the failure. Fixed. 296 [Ben Laurie] 297 298 *) DES library cleanups. 299 [Ulf M�ller] 300 301 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be 302 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit 303 ciphers. NOTE: although the key derivation function has been verified 304 against some published test vectors it has not been extensively tested 305 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use 306 of v2.0. 307 [Steve Henson] 308 309 *) Instead of "mkdir -p", which is not fully portable, use new 310 Perl script "util/mkdir-p.pl". 311 [Bodo Moeller] 312 313 *) Rewrite the way password based encryption (PBE) is handled. It used to 314 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter 315 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms 316 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now 317 the 'parameter' field of the AlgorithmIdentifier is passed to the 318 underlying key generation function so it must do its own ASN1 parsing. 319 This has also changed the EVP_PBE_CipherInit() function which now has a 320 'parameter' argument instead of literal salt and iteration count values 321 and the function EVP_PBE_ALGOR_CipherInit() has been deleted. 322 [Steve Henson] 323 324 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms 325 and PKCS#8 functionality. New 'pkcs8' application linked to openssl. 326 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE 327 KEY" because this clashed with PKCS#8 unencrypted string. Since this 328 value was just used as a "magic string" and not used directly its 329 value doesn't matter. 330 [Steve Henson] 331 332 *) Introduce some semblance of const correctness to BN. Shame C doesn't 333 support mutable. 334 [Ben Laurie] 335 336 *) "linux-sparc64" configuration (ultrapenguin). 337 [Ray Miller <ray.miller@oucs.ox.ac.uk>] 338 "linux-sparc" configuration. 339 [Christian Forster <fo@hawo.stw.uni-erlangen.de>] 340 341 *) config now generates no-xxx options for missing ciphers. 342 [Ulf M�ller] 343 344 *) Support the EBCDIC character set (work in progress). 345 File ebcdic.c not yet included because it has a different license. 346 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] 347 348 *) Support BS2000/OSD-POSIX. 349 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] 350 351 *) Make callbacks for key generation use void * instead of char *. 352 [Ben Laurie] 353 354 *) Make S/MIME samples compile (not yet tested). 355 [Ben Laurie] 356 357 *) Additional typesafe stacks. 358 [Ben Laurie] 359 360 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x). 361 [Bodo Moeller] 362 363 364 Changes between 0.9.3 and 0.9.3a [29 May 1999] 365 366 *) New configuration variant "sco5-gcc". 367 368 *) Updated some demos. 369 [Sean O Riordain, Wade Scholine] 370 371 *) Add missing BIO_free at exit of pkcs12 application. 372 [Wu Zhigang] 373 374 *) Fix memory leak in conf.c. 375 [Steve Henson] 376 377 *) Updates for Win32 to assembler version of MD5. 378 [Steve Henson] 379 380 *) Set #! path to perl in apps/der_chop to where we found it 381 instead of using a fixed path. 382 [Bodo Moeller] 383 384 *) SHA library changes for irix64-mips4-cc. 385 [Andy Polyakov] 386 387 *) Improvements for VMS support. 388 [Richard Levitte] 389 390 391 Changes between 0.9.2b and 0.9.3 [24 May 1999] 392 393 *) Bignum library bug fix. IRIX 6 passes "make test" now! 394 This also avoids the problems with SC4.2 and unpatched SC5. 395 [Andy Polyakov <appro@fy.chalmers.se>] 396 397 *) New functions sk_num, sk_value and sk_set to replace the previous macros. 398 These are required because of the typesafe stack would otherwise break 399 existing code. If old code used a structure member which used to be STACK 400 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with 401 sk_num or sk_value it would produce an error because the num, data members 402 are not present in STACK_OF. Now it just produces a warning. sk_set 403 replaces the old method of assigning a value to sk_value 404 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code 405 that does this will no longer work (and should use sk_set instead) but 406 this could be regarded as a "questionable" behaviour anyway. 407 [Steve Henson] 408 409 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now 410 correctly handle encrypted S/MIME data. 411 [Steve Henson] 412 413 *) Change type of various DES function arguments from des_cblock 414 (which means, in function argument declarations, pointer to char) 415 to des_cblock * (meaning pointer to array with 8 char elements), 416 which allows the compiler to do more typechecking; it was like 417 that back in SSLeay, but with lots of ugly casts. 418 419 Introduce new type const_des_cblock. 420 [Bodo Moeller] 421 422 *) Reorganise the PKCS#7 library and get rid of some of the more obvious 423 problems: find RecipientInfo structure that matches recipient certificate 424 and initialise the ASN1 structures properly based on passed cipher. 425 [Steve Henson] 426 427 *) Belatedly make the BN tests actually check the results. 428 [Ben Laurie] 429 430 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion 431 to and from BNs: it was completely broken. New compilation option 432 NEG_PUBKEY_BUG to allow for some broken certificates that encode public 433 key elements as negative integers. 434 [Steve Henson] 435 436 *) Reorganize and speed up MD5. 437 [Andy Polyakov <appro@fy.chalmers.se>] 438 439 *) VMS support. 440 [Richard Levitte <richard@levitte.org>] 441 442 *) New option -out to asn1parse to allow the parsed structure to be 443 output to a file. This is most useful when combined with the -strparse 444 option to examine the output of things like OCTET STRINGS. 445 [Steve Henson] 446 447 *) Make SSL library a little more fool-proof by not requiring any longer 448 that SSL_set_{accept,connect}_state be called before 449 SSL_{accept,connect} may be used (SSL_set_..._state is omitted 450 in many applications because usually everything *appeared* to work as 451 intended anyway -- now it really works as intended). 452 [Bodo Moeller] 453 454 *) Move openssl.cnf out of lib/. 455 [Ulf M�ller] 456 457 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall 458 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes 459 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ 460 [Ralf S. Engelschall] 461 462 *) Various fixes to the EVP and PKCS#7 code. It may now be able to 463 handle PKCS#7 enveloped data properly. 464 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve] 465 466 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of 467 copying pointers. The cert_st handling is changed by this in 468 various ways (and thus what used to be known as ctx->default_cert 469 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert 470 any longer when s->cert does not give us what we need). 471 ssl_cert_instantiate becomes obsolete by this change. 472 As soon as we've got the new code right (possibly it already is?), 473 we have solved a couple of bugs of the earlier code where s->cert 474 was used as if it could not have been shared with other SSL structures. 475 476 Note that using the SSL API in certain dirty ways now will result 477 in different behaviour than observed with earlier library versions: 478 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) 479 does not influence s as it used to. 480 481 In order to clean up things more thoroughly, inside SSL_SESSION 482 we don't use CERT any longer, but a new structure SESS_CERT 483 that holds per-session data (if available); currently, this is 484 the peer's certificate chain and, for clients, the server's certificate 485 and temporary key. CERT holds only those values that can have 486 meaningful defaults in an SSL_CTX. 487 [Bodo Moeller] 488 489 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure 490 from the internal representation. Various PKCS#7 fixes: remove some 491 evil casts and set the enc_dig_alg field properly based on the signing 492 key type. 493 [Steve Henson] 494 495 *) Allow PKCS#12 password to be set from the command line or the 496 environment. Let 'ca' get its config file name from the environment 497 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' 498 and 'x509'). 499 [Steve Henson] 500 501 *) Allow certificate policies extension to use an IA5STRING for the 502 organization field. This is contrary to the PKIX definition but 503 VeriSign uses it and IE5 only recognises this form. Document 'x509' 504 extension option. 505 [Steve Henson] 506 507 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, 508 without disallowing inline assembler and the like for non-pedantic builds. 509 [Ben Laurie] 510 511 *) Support Borland C++ builder. 512 [Janez Jere <jj@void.si>, modified by Ulf M�ller] 513 514 *) Support Mingw32. 515 [Ulf M�ller] 516 517 *) SHA-1 cleanups and performance enhancements. 518 [Andy Polyakov <appro@fy.chalmers.se>] 519 520 *) Sparc v8plus assembler for the bignum library. 521 [Andy Polyakov <appro@fy.chalmers.se>] 522 523 *) Accept any -xxx and +xxx compiler options in Configure. 524 [Ulf M�ller] 525 526 *) Update HPUX configuration. 527 [Anonymous] 528 529 *) Add missing sk_<type>_unshift() function to safestack.h 530 [Ralf S. Engelschall] 531 532 *) New function SSL_CTX_use_certificate_chain_file that sets the 533 "extra_cert"s in addition to the certificate. (This makes sense 534 only for "PEM" format files, as chains as a whole are not 535 DER-encoded.) 536 [Bodo Moeller] 537 538 *) Support verify_depth from the SSL API. 539 x509_vfy.c had what can be considered an off-by-one-error: 540 Its depth (which was not part of the external interface) 541 was actually counting the number of certificates in a chain; 542 now it really counts the depth. 543 [Bodo Moeller] 544 545 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used 546 instead of X509err, which often resulted in confusing error 547 messages since the error codes are not globally unique 548 (e.g. an alleged error in ssl3_accept when a certificate 549 didn't match the private key). 550 551 *) New function SSL_CTX_set_session_id_context that allows to set a default 552 value (so that you don't need SSL_set_session_id_context for each 553 connection using the SSL_CTX). 554 [Bodo Moeller] 555 556 *) OAEP decoding bug fix. 557 [Ulf M�ller] 558 559 *) Support INSTALL_PREFIX for package builders, as proposed by 560 David Harris. 561 [Bodo Moeller] 562 563 *) New Configure options "threads" and "no-threads". For systems 564 where the proper compiler options are known (currently Solaris 565 and Linux), "threads" is the default. 566 [Bodo Moeller] 567 568 *) New script util/mklink.pl as a faster substitute for util/mklink.sh. 569 [Bodo Moeller] 570 571 *) Install various scripts to $(OPENSSLDIR)/misc, not to 572 $(INSTALLTOP)/bin -- they shouldn't clutter directories 573 such as /usr/local/bin. 574 [Bodo Moeller] 575 576 *) "make linux-shared" to build shared libraries. 577 [Niels Poppe <niels@netbox.org>] 578 579 *) New Configure option no-<cipher> (rsa, idea, rc5, ...). 580 [Ulf M�ller] 581 582 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for 583 extension adding in x509 utility. 584 [Steve Henson] 585 586 *) Remove NOPROTO sections and error code comments. 587 [Ulf M�ller] 588 589 *) Partial rewrite of the DEF file generator to now parse the ANSI 590 prototypes. 591 [Steve Henson] 592 593 *) New Configure options --prefix=DIR and --openssldir=DIR. 594 [Ulf M�ller] 595 596 *) Complete rewrite of the error code script(s). It is all now handled 597 by one script at the top level which handles error code gathering, 598 header rewriting and C source file generation. It should be much better 599 than the old method: it now uses a modified version of Ulf's parser to 600 read the ANSI prototypes in all header files (thus the old K&R definitions 601 aren't needed for error creation any more) and do a better job of 602 translating function codes into names. The old 'ASN1 error code imbedded 603 in a comment' is no longer necessary and it doesn't use .err files which 604 have now been deleted. Also the error code call doesn't have to appear all 605 on one line (which resulted in some large lines...). 606 [Steve Henson] 607 608 *) Change #include filenames from <foo.h> to <openssl/foo.h>. 609 [Bodo Moeller] 610 611 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return 612 0 (which usually indicates a closed connection), but continue reading. 613 [Bodo Moeller] 614 615 *) Fix some race conditions. 616 [Bodo Moeller] 617 618 *) Add support for CRL distribution points extension. Add Certificate 619 Policies and CRL distribution points documentation. 620 [Steve Henson] 621 622 *) Move the autogenerated header file parts to crypto/opensslconf.h. 623 [Ulf M�ller] 624 625 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of 626 8 of keying material. Merlin has also confirmed interop with this fix 627 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0. 628 [Merlin Hughes <merlin@baltimore.ie>] 629 630 *) Fix lots of warnings. 631 [Richard Levitte <levitte@stacken.kth.se>] 632 633 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if 634 the directory spec didn't end with a LIST_SEPARATOR_CHAR. 635 [Richard Levitte <levitte@stacken.kth.se>] 636 637 *) Fix problems with sizeof(long) == 8. 638 [Andy Polyakov <appro@fy.chalmers.se>] 639 640 *) Change functions to ANSI C. 641 [Ulf M�ller] 642 643 *) Fix typos in error codes. 644 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf M�ller] 645 646 *) Remove defunct assembler files from Configure. 647 [Ulf M�ller] 648 649 *) SPARC v8 assembler BIGNUM implementation. 650 [Andy Polyakov <appro@fy.chalmers.se>] 651 652 *) Support for Certificate Policies extension: both print and set. 653 Various additions to support the r2i method this uses. 654 [Steve Henson] 655 656 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could 657 return a const string when you are expecting an allocated buffer. 658 [Ben Laurie] 659 660 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE 661 types DirectoryString and DisplayText. 662 [Steve Henson] 663 664 *) Add code to allow r2i extensions to access the configuration database, 665 add an LHASH database driver and add several ctx helper functions. 666 [Steve Henson] 667 668 *) Fix an evil bug in bn_expand2() which caused various BN functions to 669 fail when they extended the size of a BIGNUM. 670 [Steve Henson] 671 672 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to 673 support typesafe stack. 674 [Steve Henson] 675 676 *) Fix typo in SSL_[gs]et_options(). 677 [Nils Frostberg <nils@medcom.se>] 678 679 *) Delete various functions and files that belonged to the (now obsolete) 680 old X509V3 handling code. 681 [Steve Henson] 682 683 *) New Configure option "rsaref". 684 [Ulf M�ller] 685 686 *) Don't auto-generate pem.h. 687 [Bodo Moeller] 688 689 *) Introduce type-safe ASN.1 SETs. 690 [Ben Laurie] 691 692 *) Convert various additional casted stacks to type-safe STACK_OF() variants. 693 [Ben Laurie, Ralf S. Engelschall, Steve Henson] 694 695 *) Introduce type-safe STACKs. This will almost certainly break lots of code 696 that links with OpenSSL (well at least cause lots of warnings), but fear 697 not: the conversion is trivial, and it eliminates loads of evil casts. A 698 few STACKed things have been converted already. Feel free to convert more. 699 In the fullness of time, I'll do away with the STACK type altogether. 700 [Ben Laurie] 701 702 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate 703 specified in <certfile> by updating the entry in the index.txt file. 704 This way one no longer has to edit the index.txt file manually for 705 revoking a certificate. The -revoke option does the gory details now. 706 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall] 707 708 *) Fix `openssl crl -noout -text' combination where `-noout' killed the 709 `-text' option at all and this way the `-noout -text' combination was 710 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'. 711 [Ralf S. Engelschall] 712 713 *) Make sure a corresponding plain text error message exists for the 714 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a 715 verify callback function determined that a certificate was revoked. 716 [Ralf S. Engelschall] 717 718 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for 719 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test 720 all available cipers including rc5, which was forgotten until now. 721 In order to let the testing shell script know which algorithms 722 are available, a new (up to now undocumented) command 723 "openssl list-cipher-commands" is used. 724 [Bodo Moeller] 725 726 *) Bugfix: s_client occasionally would sleep in select() when 727 it should have checked SSL_pending() first. 728 [Bodo Moeller] 729 730 *) New functions DSA_do_sign and DSA_do_verify to provide access to 731 the raw DSA values prior to ASN.1 encoding. 732 [Ulf M�ller] 733 734 *) Tweaks to Configure 735 [Niels Poppe <niels@netbox.org>] 736 737 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, 738 yet... 739 [Steve Henson] 740 741 *) New variables $(RANLIB) and $(PERL) in the Makefiles. 742 [Ulf M�ller] 743 744 *) New config option to avoid instructions that are illegal on the 80386. 745 The default code is faster, but requires at least a 486. 746 [Ulf M�ller] 747 748 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and 749 SSL2_SERVER_VERSION (not used at all) macros, which are now the 750 same as SSL2_VERSION anyway. 751 [Bodo Moeller] 752 753 *) New "-showcerts" option for s_client. 754 [Bodo Moeller] 755 756 *) Still more PKCS#12 integration. Add pkcs12 application to openssl 757 application. Various cleanups and fixes. 758 [Steve Henson] 759 760 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and 761 modify error routines to work internally. Add error codes and PBE init 762 to library startup routines. 763 [Steve Henson] 764 765 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and 766 packing functions to asn1 and evp. Changed function names and error 767 codes along the way. 768 [Steve Henson] 769 770 *) PKCS12 integration: and so it begins... First of several patches to 771 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 772 objects to objects.h 773 [Steve Henson] 774 775 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1 776 and display support for Thawte strong extranet extension. 777 [Steve Henson] 778 779 *) Add LinuxPPC support. 780 [Jeff Dubrule <igor@pobox.org>] 781 782 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to 783 bn_div_words in alpha.s. 784 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie] 785 786 *) Make sure the RSA OAEP test is skipped under -DRSAref because 787 OAEP isn't supported when OpenSSL is built with RSAref. 788 [Ulf Moeller <ulf@fitug.de>] 789 790 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h 791 so they no longer are missing under -DNOPROTO. 792 [Soren S. Jorvang <soren@t.dk>] 793 794 795 Changes between 0.9.1c and 0.9.2b [22 Mar 1999] 796 797 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still 798 doesn't work when the session is reused. Coming soon! 799 [Ben Laurie] 800 801 *) Fix a security hole, that allows sessions to be reused in the wrong 802 context thus bypassing client cert protection! All software that uses 803 client certs and session caches in multiple contexts NEEDS PATCHING to 804 allow session reuse! A fuller solution is in the works. 805 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)] 806 807 *) Some more source tree cleanups (removed obsolete files 808 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed 809 permission on "config" script to be executable) and a fix for the INSTALL 810 document. 811 [Ulf Moeller <ulf@fitug.de>] 812 813 *) Remove some legacy and erroneous uses of malloc, free instead of 814 Malloc, Free. 815 [Lennart Bang <lob@netstream.se>, with minor changes by Steve] 816 817 *) Make rsa_oaep_test return non-zero on error. 818 [Ulf Moeller <ulf@fitug.de>] 819 820 *) Add support for native Solaris shared libraries. Configure 821 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice 822 if someone would make that last step automatic. 823 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>] 824 825 *) ctx_size was not built with the right compiler during "make links". Fixed. 826 [Ben Laurie] 827 828 *) Change the meaning of 'ALL' in the cipher list. It now means "everything 829 except NULL ciphers". This means the default cipher list will no longer 830 enable NULL ciphers. They need to be specifically enabled e.g. with 831 the string "DEFAULT:eNULL". 832 [Steve Henson] 833 834 *) Fix to RSA private encryption routines: if p < q then it would 835 occasionally produce an invalid result. This will only happen with 836 externally generated keys because OpenSSL (and SSLeay) ensure p > q. 837 [Steve Henson] 838 839 *) Be less restrictive and allow also `perl util/perlpath.pl 840 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin', 841 because this way one can also use an interpreter named `perl5' (which is 842 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still 843 installed as `perl'). 844 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 845 846 *) Let util/clean-depend.pl work also with older Perl 5.00x versions. 847 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 848 849 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add 850 advapi32.lib to Win32 build and change the pem test comparision 851 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the 852 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h 853 and crypto/des/ede_cbcm_enc.c. 854 [Steve Henson] 855 856 *) DES quad checksum was broken on big-endian architectures. Fixed. 857 [Ben Laurie] 858 859 *) Comment out two functions in bio.h that aren't implemented. Fix up the 860 Win32 test batch file so it (might) work again. The Win32 test batch file 861 is horrible: I feel ill.... 862 [Steve Henson] 863 864 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected 865 in e_os.h. Audit of header files to check ANSI and non ANSI 866 sections: 10 functions were absent from non ANSI section and not exported 867 from Windows DLLs. Fixed up libeay.num for new functions. 868 [Steve Henson] 869 870 *) Make `openssl version' output lines consistent. 871 [Ralf S. Engelschall] 872 873 *) Fix Win32 symbol export lists for BIO functions: Added 874 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data 875 to ms/libeay{16,32}.def. 876 [Ralf S. Engelschall] 877 878 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled 879 fine under Unix and passes some trivial tests I've now added. But the 880 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was 881 added to make sure no one expects that this stuff really works in the 882 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources 883 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and 884 openssl_bio.xs. 885 [Ralf S. Engelschall] 886 887 *) Fix the generation of two part addresses in perl. 888 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie] 889 890 *) Add config entry for Linux on MIPS. 891 [John Tobey <jtobey@channel1.com>] 892 893 *) Make links whenever Configure is run, unless we are on Windoze. 894 [Ben Laurie] 895 896 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf. 897 Currently only issuerAltName and AuthorityKeyIdentifier make any sense 898 in CRLs. 899 [Steve Henson] 900 901 *) Add a useful kludge to allow package maintainers to specify compiler and 902 other platforms details on the command line without having to patch the 903 Configure script everytime: One now can use ``perl Configure 904 <id>:<details>'', i.e. platform ids are allowed to have details appended 905 to them (seperated by colons). This is treated as there would be a static 906 pre-configured entry in Configure's %table under key <id> with value 907 <details> and ``perl Configure <id>'' is called. So, when you want to 908 perform a quick test-compile under FreeBSD 3.1 with pgcc and without 909 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' 910 now, which overrides the FreeBSD-elf entry on-the-fly. 911 [Ralf S. Engelschall] 912 913 *) Disable new TLS1 ciphersuites by default: they aren't official yet. 914 [Ben Laurie] 915 916 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified 917 on the `perl Configure ...' command line. This way one can compile 918 OpenSSL libraries with Position Independent Code (PIC) which is needed 919 for linking it into DSOs. 920 [Ralf S. Engelschall] 921 922 *) Remarkably, export ciphers were totally broken and no-one had noticed! 923 Fixed. 924 [Ben Laurie] 925 926 *) Cleaned up the LICENSE document: The official contact for any license 927 questions now is the OpenSSL core team under openssl-core@openssl.org. 928 And add a paragraph about the dual-license situation to make sure people 929 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply 930 to the OpenSSL toolkit. 931 [Ralf S. Engelschall] 932 933 *) General source tree makefile cleanups: Made `making xxx in yyy...' 934 display consistent in the source tree and replaced `/bin/rm' by `rm'. 935 Additonally cleaned up the `make links' target: Remove unnecessary 936 semicolons, subsequent redundant removes, inline point.sh into mklink.sh 937 to speed processing and no longer clutter the display with confusing 938 stuff. Instead only the actually done links are displayed. 939 [Ralf S. Engelschall] 940 941 *) Permit null encryption ciphersuites, used for authentication only. It used 942 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. 943 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null 944 encryption. 945 [Ben Laurie] 946 947 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder 948 signed attributes when verifying signatures (this would break them), 949 the detached data encoding was wrong and public keys obtained using 950 X509_get_pubkey() weren't freed. 951 [Steve Henson] 952 953 *) Add text documentation for the BUFFER functions. Also added a work around 954 to a Win95 console bug. This was triggered by the password read stuff: the 955 last character typed gets carried over to the next fread(). If you were 956 generating a new cert request using 'req' for example then the last 957 character of the passphrase would be CR which would then enter the first 958 field as blank. 959 [Steve Henson] 960 961 *) Added the new `Includes OpenSSL Cryptography Software' button as 962 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay 963 button and can be used by applications based on OpenSSL to show the 964 relationship to the OpenSSL project. 965 [Ralf S. Engelschall] 966 967 *) Remove confusing variables in function signatures in files 968 ssl/ssl_lib.c and ssl/ssl.h. 969 [Lennart Bong <lob@kulthea.stacken.kth.se>] 970 971 *) Don't install bss_file.c under PREFIX/include/ 972 [Lennart Bong <lob@kulthea.stacken.kth.se>] 973 974 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle 975 functions that return function pointers and has support for NT specific 976 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various 977 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from 978 unsigned to signed types: this was killing the Win32 compile. 979 [Steve Henson] 980 981 *) Add new certificate file to stack functions, 982 SSL_add_dir_cert_subjects_to_stack() and 983 SSL_add_file_cert_subjects_to_stack(). These largely supplant 984 SSL_load_client_CA_file(), and can be used to add multiple certs easily 985 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). 986 This means that Apache-SSL and similar packages don't have to mess around 987 to add as many CAs as they want to the preferred list. 988 [Ben Laurie] 989 990 *) Experiment with doxygen documentation. Currently only partially applied to 991 ssl/ssl_lib.c. 992 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with 993 openssl.doxy as the configuration file. 994 [Ben Laurie] 995 996 *) Get rid of remaining C++-style comments which strict C compilers hate. 997 [Ralf S. Engelschall, pointed out by Carlos Amengual] 998 999 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not 1000 compiled in by default: it has problems with large keys. 1001 [Steve Henson] 1002 1003 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and 1004 DH private keys and/or callback functions which directly correspond to 1005 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This 1006 is needed for applications which have to configure certificates on a 1007 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis 1008 (e.g. s_server). 1009 For the RSA certificate situation is makes no difference, but 1010 for the DSA certificate situation this fixes the "no shared cipher" 1011 problem where the OpenSSL cipher selection procedure failed because the 1012 temporary keys were not overtaken from the context and the API provided 1013 no way to reconfigure them. 1014 The new functions now let applications reconfigure the stuff and they 1015 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, 1016 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new 1017 non-public-API function ssl_cert_instantiate() is used as a helper 1018 function and also to reduce code redundancy inside ssl_rsa.c. 1019 [Ralf S. Engelschall] 1020 1021 *) Move s_server -dcert and -dkey options out of the undocumented feature 1022 area because they are useful for the DSA situation and should be 1023 recognized by the users. 1024 [Ralf S. Engelschall] 1025 1026 *) Fix the cipher decision scheme for export ciphers: the export bits are 1027 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within 1028 SSL_EXP_MASK. So, the original variable has to be used instead of the 1029 already masked variable. 1030 [Richard Levitte <levitte@stacken.kth.se>] 1031 1032 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c 1033 [Richard Levitte <levitte@stacken.kth.se>] 1034 1035 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() 1036 from `int' to `unsigned int' because it's a length and initialized by 1037 EVP_DigestFinal() which expects an `unsigned int *'. 1038 [Richard Levitte <levitte@stacken.kth.se>] 1039 1040 *) Don't hard-code path to Perl interpreter on shebang line of Configure 1041 script. Instead use the usual Shell->Perl transition trick. 1042 [Ralf S. Engelschall] 1043 1044 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates 1045 (in addition to RSA certificates) to match the behaviour of `openssl dsa 1046 -noout -modulus' as it's already the case for `openssl rsa -noout 1047 -modulus'. For RSA the -modulus is the real "modulus" while for DSA 1048 currently the public key is printed (a decision which was already done by 1049 `openssl dsa -modulus' in the past) which serves a similar purpose. 1050 Additionally the NO_RSA no longer completely removes the whole -modulus 1051 option; it now only avoids using the RSA stuff. Same applies to NO_DSA 1052 now, too. 1053 [Ralf S. Engelschall] 1054 1055 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested 1056 BIO. See the source (crypto/evp/bio_ok.c) for more info. 1057 [Arne Ansper <arne@ats.cyber.ee>] 1058 1059 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs 1060 to be added. Now both 'req' and 'ca' can use new objects defined in the 1061 config file. 1062 [Steve Henson] 1063 1064 *) Add cool BIO that does syslog (or event log on NT). 1065 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie] 1066 1067 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, 1068 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and 1069 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher 1070 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. 1071 [Ben Laurie] 1072 1073 *) Add preliminary config info for new extension code. 1074 [Steve Henson] 1075 1076 *) Make RSA_NO_PADDING really use no padding. 1077 [Ulf Moeller <ulf@fitug.de>] 1078 1079 *) Generate errors when private/public key check is done. 1080 [Ben Laurie] 1081 1082 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support 1083 for some CRL extensions and new objects added. 1084 [Steve Henson] 1085 1086 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private 1087 key usage extension and fuller support for authority key id. 1088 [Steve Henson] 1089 1090 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved 1091 padding method for RSA, which is recommended for new applications in PKCS 1092 #1 v2.0 (RFC 2437, October 1998). 1093 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical 1094 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure 1095 against Bleichbacher's attack on RSA. 1096 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by 1097 Ben Laurie] 1098 1099 *) Updates to the new SSL compression code 1100 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 1101 1102 *) Fix so that the version number in the master secret, when passed 1103 via RSA, checks that if TLS was proposed, but we roll back to SSLv3 1104 (because the server will not accept higher), that the version number 1105 is 0x03,0x01, not 0x03,0x00 1106 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 1107 1108 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory 1109 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes 1110 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c 1111 [Steve Henson] 1112 1113 *) Support for RAW extensions where an arbitrary extension can be 1114 created by including its DER encoding. See apps/openssl.cnf for 1115 an example. 1116 [Steve Henson] 1117 1118 *) Make sure latest Perl versions don't interpret some generated C array 1119 code as Perl array code in the crypto/err/err_genc.pl script. 1120 [Lars Weber <3weber@informatik.uni-hamburg.de>] 1121 1122 *) Modify ms/do_ms.bat to not generate assembly language makefiles since 1123 not many people have the assembler. Various Win32 compilation fixes and 1124 update to the INSTALL.W32 file with (hopefully) more accurate Win32 1125 build instructions. 1126 [Steve Henson] 1127 1128 *) Modify configure script 'Configure' to automatically create crypto/date.h 1129 file under Win32 and also build pem.h from pem.org. New script 1130 util/mkfiles.pl to create the MINFO file on environments that can't do a 1131 'make files': perl util/mkfiles.pl >MINFO should work. 1132 [Steve Henson] 1133 1134 *) Major rework of DES function declarations, in the pursuit of correctness 1135 and purity. As a result, many evil casts evaporated, and some weirdness, 1136 too. You may find this causes warnings in your code. Zapping your evil 1137 casts will probably fix them. Mostly. 1138 [Ben Laurie] 1139 1140 *) Fix for a typo in asn1.h. Bug fix to object creation script 1141 obj_dat.pl. It considered a zero in an object definition to mean 1142 "end of object": none of the objects in objects.h have any zeros 1143 so it wasn't spotted. 1144 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>] 1145 1146 *) Add support for Triple DES Cipher Block Chaining with Output Feedback 1147 Masking (CBCM). In the absence of test vectors, the best I have been able 1148 to do is check that the decrypt undoes the encrypt, so far. Send me test 1149 vectors if you have them. 1150 [Ben Laurie] 1151 1152 *) Correct calculation of key length for export ciphers (too much space was 1153 allocated for null ciphers). This has not been tested! 1154 [Ben Laurie] 1155 1156 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage 1157 message is now correct (it understands "crypto" and "ssl" on its 1158 command line). There is also now an "update" option. This will update 1159 the util/ssleay.num and util/libeay.num files with any new functions. 1160 If you do a: 1161 perl util/mkdef.pl crypto ssl update 1162 it will update them. 1163 [Steve Henson] 1164 1165 *) Overhauled the Perl interface (perl/*): 1166 - ported BN stuff to OpenSSL's different BN library 1167 - made the perl/ source tree CVS-aware 1168 - renamed the package from SSLeay to OpenSSL (the files still contain 1169 their history because I've copied them in the repository) 1170 - removed obsolete files (the test scripts will be replaced 1171 by better Test::Harness variants in the future) 1172 [Ralf S. Engelschall] 1173 1174 *) First cut for a very conservative source tree cleanup: 1175 1. merge various obsolete readme texts into doc/ssleay.txt 1176 where we collect the old documents and readme texts. 1177 2. remove the first part of files where I'm already sure that we no 1178 longer need them because of three reasons: either they are just temporary 1179 files which were left by Eric or they are preserved original files where 1180 I've verified that the diff is also available in the CVS via "cvs diff 1181 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for 1182 the crypto/md/ stuff). 1183 [Ralf S. Engelschall] 1184 1185 *) More extension code. Incomplete support for subject and issuer alt 1186 name, issuer and authority key id. Change the i2v function parameters 1187 and add an extra 'crl' parameter in the X509V3_CTX structure: guess 1188 what that's for :-) Fix to ASN1 macro which messed up 1189 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. 1190 [Steve Henson] 1191 1192 *) Preliminary support for ENUMERATED type. This is largely copied from the 1193 INTEGER code. 1194 [Steve Henson] 1195 1196 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. 1197 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 1198 1199 *) Make sure `make rehash' target really finds the `openssl' program. 1200 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 1201 1202 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd 1203 like to hear about it if this slows down other processors. 1204 [Ben Laurie] 1205 1206 *) Add CygWin32 platform information to Configure script. 1207 [Alan Batie <batie@aahz.jf.intel.com>] 1208 1209 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' 1210 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>] 1211 1212 *) New program nseq to manipulate netscape certificate sequences 1213 [Steve Henson] 1214 1215 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a 1216 few typos. 1217 [Steve Henson] 1218 1219 *) Fixes to BN code. Previously the default was to define BN_RECURSION 1220 but the BN code had some problems that would cause failures when 1221 doing certificate verification and some other functions. 1222 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 1223 1224 *) Add ASN1 and PEM code to support netscape certificate sequences. 1225 [Steve Henson] 1226 1227 *) Add ASN1 and PEM code to support netscape certificate sequences. 1228 [Steve Henson] 1229 1230 *) Add several PKIX and private extended key usage OIDs. 1231 [Steve Henson] 1232 1233 *) Modify the 'ca' program to handle the new extension code. Modify 1234 openssl.cnf for new extension format, add comments. 1235 [Steve Henson] 1236 1237 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' 1238 and add a sample to openssl.cnf so req -x509 now adds appropriate 1239 CA extensions. 1240 [Steve Henson] 1241 1242 *) Continued X509 V3 changes. Add to other makefiles, integrate with the 1243 error code, add initial support to X509_print() and x509 application. 1244 [Steve Henson] 1245 1246 *) Takes a deep breath and start addding X509 V3 extension support code. Add 1247 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this 1248 stuff is currently isolated and isn't even compiled yet. 1249 [Steve Henson] 1250 1251 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL 1252 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. 1253 Removed the versions check from X509 routines when loading extensions: 1254 this allows certain broken certificates that don't set the version 1255 properly to be processed. 1256 [Steve Henson] 1257 1258 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another 1259 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which 1260 can still be regenerated with "make depend". 1261 [Ben Laurie] 1262 1263 *) Spelling mistake in C version of CAST-128. 1264 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>] 1265 1266 *) Changes to the error generation code. The perl script err-code.pl 1267 now reads in the old error codes and retains the old numbers, only 1268 adding new ones if necessary. It also only changes the .err files if new 1269 codes are added. The makefiles have been modified to only insert errors 1270 when needed (to avoid needlessly modifying header files). This is done 1271 by only inserting errors if the .err file is newer than the auto generated 1272 C file. To rebuild all the error codes from scratch (the old behaviour) 1273 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl 1274 or delete all the .err files. 1275 [Steve Henson] 1276 1277 *) CAST-128 was incorrectly implemented for short keys. The C version has 1278 been fixed, but is untested. The assembler versions are also fixed, but 1279 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing 1280 to regenerate it if needed. 1281 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun 1282 Hagino <itojun@kame.net>] 1283 1284 *) File was opened incorrectly in randfile.c. 1285 [Ulf M�ller <ulf@fitug.de>] 1286 1287 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print 1288 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or 1289 GeneralizedTime. ASN1_TIME is the proper type used in certificates et 1290 al: it's just almost always a UTCTime. Note this patch adds new error 1291 codes so do a "make errors" if there are problems. 1292 [Steve Henson] 1293 1294 *) Correct Linux 1 recognition in config. 1295 [Ulf M�ller <ulf@fitug.de>] 1296 1297 *) Remove pointless MD5 hash when using DSA keys in ca. 1298 [Anonymous <nobody@replay.com>] 1299 1300 *) Generate an error if given an empty string as a cert directory. Also 1301 generate an error if handed NULL (previously returned 0 to indicate an 1302 error, but didn't set one). 1303 [Ben Laurie, reported by Anonymous <nobody@replay.com>] 1304 1305 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. 1306 [Ben Laurie] 1307 1308 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct 1309 parameters. This was causing a warning which killed off the Win32 compile. 1310 [Steve Henson] 1311 1312 *) Remove C++ style comments from crypto/bn/bn_local.h. 1313 [Neil Costigan <neil.costigan@celocom.com>] 1314 1315 *) The function OBJ_txt2nid was broken. It was supposed to return a nid 1316 based on a text string, looking up short and long names and finally 1317 "dot" format. The "dot" format stuff didn't work. Added new function 1318 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote 1319 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the 1320 OID is not part of the table. 1321 [Steve Henson] 1322 1323 *) Add prototypes to X509 lookup/verify methods, fixing a bug in 1324 X509_LOOKUP_by_alias(). 1325 [Ben Laurie] 1326 1327 *) Sort openssl functions by name. 1328 [Ben Laurie] 1329 1330 *) Get the gendsa program working (hopefully) and add it to app list. Remove 1331 encryption from sample DSA keys (in case anyone is interested the password 1332 was "1234"). 1333 [Steve Henson] 1334 1335 *) Make _all_ *_free functions accept a NULL pointer. 1336 [Frans Heymans <fheymans@isaserver.be>] 1337 1338 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use 1339 NULL pointers. 1340 [Anonymous <nobody@replay.com>] 1341 1342 *) s_server should send the CAfile as acceptable CAs, not its own cert. 1343 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] 1344 1345 *) Don't blow it for numeric -newkey arguments to apps/req. 1346 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] 1347 1348 *) Temp key "for export" tests were wrong in s3_srvr.c. 1349 [Anonymous <nobody@replay.com>] 1350 1351 *) Add prototype for temp key callback functions 1352 SSL_CTX_set_tmp_{rsa,dh}_callback(). 1353 [Ben Laurie] 1354 1355 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and 1356 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). 1357 [Steve Henson] 1358 1359 *) X509_name_add_entry() freed the wrong thing after an error. 1360 [Arne Ansper <arne@ats.cyber.ee>] 1361 1362 *) rsa_eay.c would attempt to free a NULL context. 1363 [Arne Ansper <arne@ats.cyber.ee>] 1364 1365 *) BIO_s_socket() had a broken should_retry() on Windoze. 1366 [Arne Ansper <arne@ats.cyber.ee>] 1367 1368 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. 1369 [Arne Ansper <arne@ats.cyber.ee>] 1370 1371 *) Make sure the already existing X509_STORE->depth variable is initialized 1372 in X509_STORE_new(), but document the fact that this variable is still 1373 unused in the certificate verification process. 1374 [Ralf S. Engelschall] 1375 1376 *) Fix the various library and apps files to free up pkeys obtained from 1377 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. 1378 [Steve Henson] 1379 1380 *) Fix reference counting in X509_PUBKEY_get(). This makes 1381 demos/maurice/example2.c work, amongst others, probably. 1382 [Steve Henson and Ben Laurie] 1383 1384 *) First cut of a cleanup for apps/. First the `ssleay' program is now named 1385 `openssl' and second, the shortcut symlinks for the `openssl <command>' 1386 are no longer created. This way we have a single and consistent command 1387 line interface `openssl <command>', similar to `cvs <command>'. 1388 [Ralf S. Engelschall, Paul Sutton and Ben Laurie] 1389 1390 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey 1391 BIT STRING wrapper always have zero unused bits. 1392 [Steve Henson] 1393 1394 *) Add CA.pl, perl version of CA.sh, add extended key usage OID. 1395 [Steve Henson] 1396 1397 *) Make the top-level INSTALL documentation easier to understand. 1398 [Paul Sutton] 1399 1400 *) Makefiles updated to exit if an error occurs in a sub-directory 1401 make (including if user presses ^C) [Paul Sutton] 1402 1403 *) Make Montgomery context stuff explicit in RSA data structure. 1404 [Ben Laurie] 1405 1406 *) Fix build order of pem and err to allow for generated pem.h. 1407 [Ben Laurie] 1408 1409 *) Fix renumbering bug in X509_NAME_delete_entry(). 1410 [Ben Laurie] 1411 1412 *) Enhanced the err-ins.pl script so it makes the error library number 1413 global and can add a library name. This is needed for external ASN1 and 1414 other error libraries. 1415 [Steve Henson] 1416 1417 *) Fixed sk_insert which never worked properly. 1418 [Steve Henson] 1419 1420 *) Fix ASN1 macros so they can handle indefinite length construted 1421 EXPLICIT tags. Some non standard certificates use these: they can now 1422 be read in. 1423 [Steve Henson] 1424 1425 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) 1426 into a single doc/ssleay.txt bundle. This way the information is still 1427 preserved but no longer messes up this directory. Now it's new room for 1428 the new set of documenation files. 1429 [Ralf S. Engelschall] 1430 1431 *) SETs were incorrectly DER encoded. This was a major pain, because they 1432 shared code with SEQUENCEs, which aren't coded the same. This means that 1433 almost everything to do with SETs or SEQUENCEs has either changed name or 1434 number of arguments. 1435 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>] 1436 1437 *) Fix test data to work with the above. 1438 [Ben Laurie] 1439 1440 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but 1441 was already fixed by Eric for 0.9.1 it seems. 1442 [Ben Laurie - pointed out by Ulf M�ller <ulf@fitug.de>] 1443 1444 *) Autodetect FreeBSD3. 1445 [Ben Laurie] 1446 1447 *) Fix various bugs in Configure. This affects the following platforms: 1448 nextstep 1449 ncr-scde 1450 unixware-2.0 1451 unixware-2.0-pentium 1452 sco5-cc. 1453 [Ben Laurie] 1454 1455 *) Eliminate generated files from CVS. Reorder tests to regenerate files 1456 before they are needed. 1457 [Ben Laurie] 1458 1459 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy). 1460 [Ben Laurie] 1461 1462 1463 Changes between 0.9.1b and 0.9.1c [23-Dec-1998] 1464 1465 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and 1466 changed SSLeay to OpenSSL in version strings. 1467 [Ralf S. Engelschall] 1468 1469 *) Some fixups to the top-level documents. 1470 [Paul Sutton] 1471 1472 *) Fixed the nasty bug where rsaref.h was not found under compile-time 1473 because the symlink to include/ was missing. 1474 [Ralf S. Engelschall] 1475 1476 *) Incorporated the popular no-RSA/DSA-only patches 1477 which allow to compile a RSA-free SSLeay. 1478 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall] 1479 1480 *) Fixed nasty rehash problem under `make -f Makefile.ssl links' 1481 when "ssleay" is still not found. 1482 [Ralf S. Engelschall] 1483 1484 *) Added more platforms to Configure: Cray T3E, HPUX 11, 1485 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>] 1486 1487 *) Updated the README file. 1488 [Ralf S. Engelschall] 1489 1490 *) Added various .cvsignore files in the CVS repository subdirs 1491 to make a "cvs update" really silent. 1492 [Ralf S. Engelschall] 1493 1494 *) Recompiled the error-definition header files and added 1495 missing symbols to the Win32 linker tables. 1496 [Ralf S. Engelschall] 1497 1498 *) Cleaned up the top-level documents; 1499 o new files: CHANGES and LICENSE 1500 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay 1501 o merged COPYRIGHT into LICENSE 1502 o removed obsolete TODO file 1503 o renamed MICROSOFT to INSTALL.W32 1504 [Ralf S. Engelschall] 1505 1506 *) Removed dummy files from the 0.9.1b source tree: 1507 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi 1508 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f 1509 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f 1510 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f 1511 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f 1512 [Ralf S. Engelschall] 1513 1514 *) Added various platform portability fixes. 1515 [Mark J. Cox] 1516 1517 *) The Genesis of the OpenSSL rpject: 1518 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A. 1519 Young and Tim J. Hudson created while they were working for C2Net until 1520 summer 1998. 1521 [The OpenSSL Project] 1522 1523 1524 Changes between 0.9.0b and 0.9.1b [not released] 1525 1526 *) Updated a few CA certificates under certs/ 1527 [Eric A. Young] 1528 1529 *) Changed some BIGNUM api stuff. 1530 [Eric A. Young] 1531 1532 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD, 1533 DGUX x86, Linux Alpha, etc. 1534 [Eric A. Young] 1535 1536 *) New COMP library [crypto/comp/] for SSL Record Layer Compression: 1537 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is 1538 available). 1539 [Eric A. Young] 1540 1541 *) Add -strparse option to asn1pars program which parses nested 1542 binary structures 1543 [Dr Stephen Henson <shenson@bigfoot.com>] 1544 1545 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs. 1546 [Eric A. Young] 1547 1548 *) DSA fix for "ca" program. 1549 [Eric A. Young] 1550 1551 *) Added "-genkey" option to "dsaparam" program. 1552 [Eric A. Young] 1553 1554 *) Added RIPE MD160 (rmd160) message digest. 1555 [Eric A. Young] 1556 1557 *) Added -a (all) option to "ssleay version" command. 1558 [Eric A. Young] 1559 1560 *) Added PLATFORM define which is the id given to Configure. 1561 [Eric A. Young] 1562 1563 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking. 1564 [Eric A. Young] 1565 1566 *) Extended the ASN.1 parser routines. 1567 [Eric A. Young] 1568 1569 *) Extended BIO routines to support REUSEADDR, seek, tell, etc. 1570 [Eric A. Young] 1571 1572 *) Added a BN_CTX to the BN library. 1573 [Eric A. Young] 1574 1575 *) Fixed the weak key values in DES library 1576 [Eric A. Young] 1577 1578 *) Changed API in EVP library for cipher aliases. 1579 [Eric A. Young] 1580 1581 *) Added support for RC2/64bit cipher. 1582 [Eric A. Young] 1583 1584 *) Converted the lhash library to the crypto/mem.c functions. 1585 [Eric A. Young] 1586 1587 *) Added more recognized ASN.1 object ids. 1588 [Eric A. Young] 1589 1590 *) Added more RSA padding checks for SSL/TLS. 1591 [Eric A. Young] 1592 1593 *) Added BIO proxy/filter functionality. 1594 [Eric A. Young] 1595 1596 *) Added extra_certs to SSL_CTX which can be used 1597 send extra CA certificates to the client in the CA cert chain sending 1598 process. It can be configured with SSL_CTX_add_extra_chain_cert(). 1599 [Eric A. Young] 1600 1601 *) Now Fortezza is denied in the authentication phase because 1602 this is key exchange mechanism is not supported by SSLeay at all. 1603 [Eric A. Young] 1604 1605 *) Additional PKCS1 checks. 1606 [Eric A. Young] 1607 1608 *) Support the string "TLSv1" for all TLS v1 ciphers. 1609 [Eric A. Young] 1610 1611 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the 1612 ex_data index of the SSL context in the X509_STORE_CTX ex_data. 1613 [Eric A. Young] 1614 1615 *) Fixed a few memory leaks. 1616 [Eric A. Young] 1617 1618 *) Fixed various code and comment typos. 1619 [Eric A. Young] 1620 1621 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0 1622 bytes sent in the client random. 1623 [Edward Bishop <ebishop@spyglass.com>] 1624 1625
