An attacker using a carefully crafted 8109998Smarkm handshake can force the use of weak keying material in OpenSSL 9109998Smarkm SSL/TLS clients and servers. 10109998Smarkm 11109998Smarkm Thanks to KIKUCHI Masashi (Lepidum Co. Ltd.) for discovering and 12109998Smarkm researching this issue. (CVE-2014-0224) 13109998Smarkm [KIKUCHI Masashi, Steve Henson] 14109998Smarkm 15109998Smarkm *) Fix DTLS recursion flaw. By sending an invalid DTLS handshake to an 16109998Smarkm OpenSSL DTLS client the code can be made to recurse eventually crashing 17109998Smarkm in a DoS attack. 18109998Smarkm 19109998Smarkm Thanks to Imre Rad (Search-Lab Ltd.) for discovering this issue. 20109998Smarkm (CVE-2014-0221) 21109998Smarkm [Imre Rad, Steve Henson] 22109998Smarkm 23109998Smarkm *) Fix DTLS invalid fragment vulnerability. A buffer overrun attack can 24109998Smarkm be triggered by sending invalid DTLS fragments to an OpenSSL DTLS 25109998Smarkm client or server. This is potentially exploitable to run arbitrary 26109998Smarkm code on a vulnerable client or server. 27109998Smarkm 28109998Smarkm Thanks to J�ri Aedla for reporting this issue. (CVE-2014-0195) 29109998Smarkm [J�ri Aedla, Steve Henson] 30109998Smarkm 31109998Smarkm *) Fix bug in TLS code where clients enable anonymous ECDH ciphersuites 32109998Smarkm are subject to a denial of service attack. 33109998Smarkm 34109998Smarkm Thanks to Felix Gr�bert and Ivan Fratric at Google for discovering 35109998Smarkm this issue. (CVE-2014-3470) 36109998Smarkm [Felix Gr�bert, Ivan Fratric, Steve Henson] 37109998Smarkm 38109998Smarkm *) Harmonize version and its documentation. -f flag is used to display 39109998Smarkm compilation flags. 40109998Smarkm [mancha <mancha1@zoho.com>] 41109998Smarkm 42109998Smarkm *) Fix eckey_priv_encode so it immediately returns an error upon a failure 43109998Smarkm in i2d_ECPrivateKey. 44109998Smarkm [mancha <mancha1@zoho.com>] 45109998Smarkm 46109998Smarkm *) Fix some double frees. These are not thought to be exploitable. 47109998Smarkm [mancha <mancha1@zoho.com>] 48109998Smarkm 49109998Smarkm Changes between 1.0.1f and 1.0.1g [7 Apr 2014] 50109998Smarkm 51109998Smarkm *) A missing bounds check in the handling of the TLS heartbeat extension 52109998Smarkm can be used to reveal up to 64k of memory to a connected client or 53109998Smarkm server. 54109998Smarkm 55109998Smarkm Thanks for Neel Mehta of Google Security for discovering this bug and to 56109998Smarkm Adam Langley <agl@chromium.org> and Bodo Moeller <bmoeller@acm.org> for 57109998Smarkm preparing the fix (CVE-2014-0160) 58109998Smarkm [Adam Langley, Bodo Moeller] 59109998Smarkm 60109998Smarkm *) Fix for the attack described in the paper "Recovering OpenSSL 61109998Smarkm ECDSA Nonces Using the FLUSH+RELOAD Cache Side-channel Attack" 62109998Smarkm by Yuval Yarom and Naomi Benger. Details can be obtained from: 63109998Smarkm http://eprint.iacr.org/2014/140 64109998Smarkm 65109998Smarkm Thanks to Yuval Yarom and Naomi Benger for discovering this 66109998Smarkm flaw and to Yuval Yarom for supplying a fix (CVE-2014-0076) 67109998Smarkm [Yuval Yarom and Naomi Benger] 68109998Smarkm 69109998Smarkm *) TLS pad extension: draft-agl-tls-padding-03 70109998Smarkm 71109998Smarkm Workaround for the "TLS hang bug" (see FAQ and PR#2771): if the 72109998Smarkm TLS client Hello record length value would otherwise be > 255 and 73109998Smarkm less that 512 pad with a dummy extension containing zeroes so it 74109998Smarkm is at least 512 bytes long. 75109998Smarkm 76109998Smarkm [Adam Langley, Steve Henson] 77109998Smarkm 78109998Smarkm Changes between 1.0.1e and 1.0.1f [6 Jan 2014] 79109998Smarkm 80109998Smarkm *) Fix for TLS record tampering bug. A carefully crafted invalid 81109998Smarkm handshake could crash OpenSSL with a NULL pointer exception. 82109998Smarkm Thanks to Anton Johansson for reporting this issues. 83109998Smarkm (CVE-2013-4353) 84109998Smarkm 85109998Smarkm *) Keep original DTLS digest and encryption contexts in retransmission 86109998Smarkm structures so we can use the previous session parameters if they need 87109998Smarkm to be resent. (CVE-2013-6450) 88109998Smarkm [Steve Henson] 89109998Smarkm 90109998Smarkm *) Add option SSL_OP_SAFARI_ECDHE_ECDSA_BUG (part of SSL_OP_ALL) which 91109998Smarkm avoids preferring ECDHE-ECDSA ciphers when the client appears to be 92109998Smarkm Safari on OS X. Safari on OS X 10.8..10.8.3 advertises support for 93109998Smarkm several ECDHE-ECDSA ciphers, but fails to negotiate them. The bug 94109998Smarkm is fixed in OS X 10.8.4, but Apple have ruled out both hot fixing 95109998Smarkm 10.8..10.8.3 and forcing users to upgrade to 10.8.4 or newer. 96109998Smarkm [Rob Stradling, Adam Langley] 97109998Smarkm 98109998Smarkm Changes between 1.0.1d and 1.0.1e [11 Feb 2013] 99109998Smarkm 100109998Smarkm *) Correct fix for CVE-2013-0169. The original didn't work on AES-NI 101109998Smarkm supporting platforms or when small records were transferred. 102109998Smarkm [Andy Polyakov, Steve Henson] 103109998Smarkm 104109998Smarkm Changes between 1.0.1c and 1.0.1d [5 Feb 2013] 105109998Smarkm 106109998Smarkm *) Make the decoding of SSLv3, TLS and DTLS CBC records constant time. 107109998Smarkm 108109998Smarkm This addresses the flaw in CBC record processing discovered by 109109998Smarkm Nadhem Alfardan and Kenny Paterson. Details of this attack can be found 110109998Smarkm at: http://www.isg.rhul.ac.uk/tls/ 111109998Smarkm 112109998Smarkm Thanks go to Nadhem Alfardan and Kenny Paterson of the Information 113109998Smarkm Security Group at Royal Holloway, University of London 114109998Smarkm (www.isg.rhul.ac.uk) for discovering this flaw and Adam Langley and 115109998Smarkm Emilia K�sper for the initial patch. 116109998Smarkm (CVE-2013-0169) 117109998Smarkm [Emilia K�sper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson] 118109998Smarkm 119109998Smarkm *) Fix flaw in AESNI handling of TLS 1.2 and 1.1 records for CBC mode 120109998Smarkm ciphersuites which can be exploited in a denial of service attack. 121109998Smarkm Thanks go to and to Adam Langley <agl@chromium.org> for discovering 122109998Smarkm and detecting this bug and to Wolfgang Ettlinger 123109998Smarkm <wolfgang.ettlinger@gmail.com> for independently discovering this issue. 124109998Smarkm (CVE-2012-2686) 125109998Smarkm [Adam Langley] 126109998Smarkm 127109998Smarkm *) Return an error when checking OCSP signatures when key is NULL. 128109998Smarkm This fixes a DoS attack. (CVE-2013-0166) 129109998Smarkm [Steve Henson] 130109998Smarkm 131109998Smarkm *) Make openssl verify return errors. 132109998Smarkm [Chris Palmer <palmer@google.com> and Ben Laurie] 133109998Smarkm 134109998Smarkm *) Call OCSP Stapling callback after ciphersuite has been chosen, so 135109998Smarkm the right response is stapled. Also change SSL_get_certificate() 136109998Smarkm so it returns the certificate actually sent. 137109998Smarkm See http://rt.openssl.org/Ticket/Display.html?id=2836. 138109998Smarkm [Rob Stradling <rob.stradling@comodo.com>] 139109998Smarkm 140109998Smarkm *) Fix possible deadlock when decoding public keys. 141109998Smarkm [Steve Henson] 142109998Smarkm 143109998Smarkm *) Don't use TLS 1.0 record version number in initial client hello 144109998Smarkm if renegotiating. 145109998Smarkm [Steve Henson] 146109998Smarkm 147109998Smarkm Changes between 1.0.1b and 1.0.1c [10 May 2012] 148109998Smarkm 149109998Smarkm *) Sanity check record length before skipping explicit IV in TLS 150109998Smarkm 1.2, 1.1 and DTLS to fix DoS attack. 151109998Smarkm 152109998Smarkm Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic 153109998Smarkm fuzzing as a service testing platform. 154109998Smarkm (CVE-2012-2333) 155109998Smarkm [Steve Henson] 156109998Smarkm 157109998Smarkm *) Initialise tkeylen properly when encrypting CMS messages. 158109998Smarkm Thanks to Solar Designer of Openwall for reporting this issue. 159109998Smarkm [Steve Henson] 160109998Smarkm 161109998Smarkm *) In FIPS mode don't try to use composite ciphers as they are not 162109998Smarkm approved. 163109998Smarkm [Steve Henson] 164109998Smarkm 165109998Smarkm Changes between 1.0.1a and 1.0.1b [26 Apr 2012] 166109998Smarkm 167109998Smarkm *) OpenSSL 1.0.0 sets SSL_OP_ALL to 0x80000FFFL and OpenSSL 1.0.1 and 168109998Smarkm 1.0.1a set SSL_OP_NO_TLSv1_1 to 0x00000400L which would unfortunately 169109998Smarkm mean any application compiled against OpenSSL 1.0.0 headers setting 170109998Smarkm SSL_OP_ALL would also set SSL_OP_NO_TLSv1_1, unintentionally disablng 171109998Smarkm TLS 1.1 also. Fix this by changing the value of SSL_OP_NO_TLSv1_1 to 172109998Smarkm 0x10000000L Any application which was previously compiled against 173109998Smarkm OpenSSL 1.0.1 or 1.0.1a headers and which cares about SSL_OP_NO_TLSv1_1 174109998Smarkm will need to be recompiled as a result. Letting be results in 175109998Smarkm inability to disable specifically TLS 1.1 and in client context, 176109998Smarkm in unlike event, limit maximum offered version to TLS 1.0 [see below]. 177109998Smarkm [Steve Henson] 178109998Smarkm 179109998Smarkm *) In order to ensure interoperabilty SSL_OP_NO_protocolX does not 180109998Smarkm disable just protocol X, but all protocols above X *if* there are 181109998Smarkm protocols *below* X still enabled. In more practical terms it means 182109998Smarkm that if application wants to disable TLS1.0 in favor of TLS1.1 and 183109998Smarkm above, it's not sufficient to pass SSL_OP_NO_TLSv1, one has to pass 184109998Smarkm SSL_OP_NO_TLSv1|SSL_OP_NO_SSLv3|SSL_OP_NO_SSLv2. This applies to 185109998Smarkm client side. 186109998Smarkm [Andy Polyakov] 187109998Smarkm 188109998Smarkm Changes between 1.0.1 and 1.0.1a [19 Apr 2012] 189109998Smarkm 190109998Smarkm *) Check for potentially exploitable overflows in asn1_d2i_read_bio 191109998Smarkm BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer 192109998Smarkm in CRYPTO_realloc_clean. 193109998Smarkm 194109998Smarkm Thanks to Tavis Ormandy, Google Security Team, for discovering this 195109998Smarkm issue and to Adam Langley <agl@chromium.org> for fixing it. 196109998Smarkm (CVE-2012-2110) 197109998Smarkm [Adam Langley (Google), Tavis Ormandy, Google Security Team] 198109998Smarkm 199109998Smarkm *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections. 200109998Smarkm [Adam Langley] 201109998Smarkm 202109998Smarkm *) Workarounds for some broken servers that "hang" if a client hello 203109998Smarkm record length exceeds 255 bytes. 204109998Smarkm 205109998Smarkm 1. Do not use record version number > TLS 1.0 in initial client 206109998Smarkm hello: some (but not all) hanging servers will now work. 207109998Smarkm 2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate 208109998Smarkm the number of ciphers sent in the client hello. This should be 209109998Smarkm set to an even number, such as 50, for example by passing: 210109998Smarkm -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure. 211109998Smarkm Most broken servers should now work. 212109998Smarkm 3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable 213109998Smarkm TLS 1.2 client support entirely. 214109998Smarkm [Steve Henson] 215109998Smarkm 216109998Smarkm *) Fix SEGV in Vector Permutation AES module observed in OpenSSH. 217109998Smarkm [Andy Polyakov] 218109998Smarkm 219109998Smarkm Changes between 1.0.0h and 1.0.1 [14 Mar 2012] 220109998Smarkm 221109998Smarkm *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET 222109998Smarkm STRING form instead of a DigestInfo. 223109998Smarkm [Steve Henson] 224109998Smarkm 225109998Smarkm *) The format used for MDC2 RSA signatures is inconsistent between EVP 226109998Smarkm and the RSA_sign/RSA_verify functions. This was made more apparent when 227109998Smarkm OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular 228109998Smarkm those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect 229109998Smarkm the correct format in RSA_verify so both forms transparently work. 230109998Smarkm [Steve Henson] 231109998Smarkm 232109998Smarkm *) Some servers which support TLS 1.0 can choke if we initially indicate 233109998Smarkm support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA 234109998Smarkm encrypted premaster secret. As a workaround use the maximum pemitted 235109998Smarkm client version in client hello, this should keep such servers happy 236109998Smarkm and still work with previous versions of OpenSSL. 237109998Smarkm [Steve Henson] 238109998Smarkm 239109998Smarkm *) Add support for TLS/DTLS heartbeats. 240109998Smarkm [Robin Seggelmann <seggelmann@fh-muenster.de>] 241109998Smarkm 242109998Smarkm *) Add support for SCTP. 243109998Smarkm [Robin Seggelmann <seggelmann@fh-muenster.de>] 244109998Smarkm 245109998Smarkm *) Improved PRNG seeding for VOS. 246109998Smarkm [Paul Green <Paul.Green@stratus.com>] 247109998Smarkm 248109998Smarkm *) Extensive assembler packs updates, most notably: 249109998Smarkm 250109998Smarkm - x86[_64]: AES-NI, PCLMULQDQ, RDRAND support; 251109998Smarkm - x86[_64]: SSSE3 support (SHA1, vector-permutation AES); 252109998Smarkm - x86_64: bit-sliced AES implementation; 253109998Smarkm - ARM: NEON support, contemporary platforms optimizations; 254109998Smarkm - s390x: z196 support; 255109998Smarkm - *: GHASH and GF(2^m) multiplication implementations; 256109998Smarkm 257109998Smarkm [Andy Polyakov] 258109998Smarkm 259109998Smarkm *) Make TLS-SRP code conformant with RFC 5054 API cleanup 260109998Smarkm (removal of unnecessary code) 261109998Smarkm [Peter Sylvester <peter.sylvester@edelweb.fr>] 262109998Smarkm 263109998Smarkm *) Add TLS key material exporter from RFC 5705. 264109998Smarkm [Eric Rescorla] 265109998Smarkm 266109998Smarkm *) Add DTLS-SRTP negotiation from RFC 5764. 267109998Smarkm [Eric Rescorla] 268109998Smarkm 269109998Smarkm *) Add Next Protocol Negotiation, 270109998Smarkm http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00. Can be 271109998Smarkm disabled with a no-npn flag to config or Configure. Code donated 272109998Smarkm by Google. 273109998Smarkm [Adam Langley <agl@google.com> and Ben Laurie] 274109998Smarkm 275109998Smarkm *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224, 276109998Smarkm NIST-P256, NIST-P521, with constant-time single point multiplication on 277109998Smarkm typical inputs. Compiler support for the nonstandard type __uint128_t is 278109998Smarkm required to use this (present in gcc 4.4 and later, for 64-bit builds). 279109998Smarkm Code made available under Apache License version 2.0. 280109998Smarkm 281109998Smarkm Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command 282109998Smarkm line to include this in your build of OpenSSL, and run "make depend" (or 283109998Smarkm "make update"). This enables the following EC_METHODs: 284109998Smarkm 285109998Smarkm EC_GFp_nistp224_method() 286109998Smarkm EC_GFp_nistp256_method() 287109998Smarkm EC_GFp_nistp521_method() 288109998Smarkm 289109998Smarkm EC_GROUP_new_by_curve_name() will automatically use these (while 290109998Smarkm EC_GROUP_new_curve_GFp() currently prefers the more flexible 291109998Smarkm implementations). 292109998Smarkm [Emilia K�sper, Adam Langley, Bodo Moeller (Google)] 293109998Smarkm 294109998Smarkm *) Use type ossl_ssize_t instad of ssize_t which isn't available on 295109998Smarkm all platforms. Move ssize_t definition from e_os.h to the public 296109998Smarkm header file e_os2.h as it now appears in public header file cms.h 297109998Smarkm [Steve Henson] 298109998Smarkm 299109998Smarkm *) New -sigopt option to the ca, req and x509 utilities. Additional 300109998Smarkm signature parameters can be passed using this option and in 301109998Smarkm particular PSS. 302109998Smarkm [Steve Henson] 303109998Smarkm 304109998Smarkm *) Add RSA PSS signing function. This will generate and set the 305109998Smarkm appropriate AlgorithmIdentifiers for PSS based on those in the 306109998Smarkm corresponding EVP_MD_CTX structure. No application support yet. 307109998Smarkm [Steve Henson] 308109998Smarkm 309109998Smarkm *) Support for companion algorithm specific ASN1 signing routines. 310109998Smarkm New function ASN1_item_sign_ctx() signs a pre-initialised 311109998Smarkm EVP_MD_CTX structure and sets AlgorithmIdentifiers based on 312109998Smarkm the appropriate parameters. 313109998Smarkm [Steve Henson] 314109998Smarkm 315109998Smarkm *) Add new algorithm specific ASN1 verification initialisation function 316109998Smarkm to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1 317109998Smarkm handling will be the same no matter what EVP_PKEY_METHOD is used. 318109998Smarkm Add a PSS handler to support verification of PSS signatures: checked 319109998Smarkm against a number of sample certificates. 320109998Smarkm [Steve Henson] 321109998Smarkm 322109998Smarkm *) Add signature printing for PSS. Add PSS OIDs. 323109998Smarkm [Steve Henson, Martin Kaiser <lists@kaiser.cx>] 324109998Smarkm 325109998Smarkm *) Add algorithm specific signature printing.

The new 811109998Smarkm form uses the canonical encoding (meaning equivalent names will work 812109998Smarkm even if they aren't identical) and uses SHA1 instead of MD5. This form 813109998Smarkm is incompatible with the older format and as a result c_rehash should 814109998Smarkm be used to rebuild symbolic links. 815109998Smarkm [Steve Henson] 816109998Smarkm 817109998Smarkm *) Make PKCS#8 the default write format for private keys, replacing the 818109998Smarkm traditional format.

This avoids any issues with OS routines such 845109998Smarkm as the year 2038 bug. New *_adj() functions for ASN1 time structures 846109998Smarkm and X509_time_adj_ex() to cover the extended range. The existing 847109998Smarkm X509_time_adj() is still usable and will no longer have any date issues. 848109998Smarkm [Steve Henson] 849109998Smarkm 850109998Smarkm *) Delta CRL support. New use deltas option which will attempt to locate 851109998Smarkm and search any appropriate delta CRLs available. 852109998Smarkm 853109998Smarkm This work was sponsored by Google. 854109998Smarkm [Steve Henson] 855109998Smarkm 856109998Smarkm *) Support for CRLs partitioned by reason code. Reorganise CRL processing 857109998Smarkm code and add additional score elements. Validate alternate CRL paths 858109998Smarkm as part of the CRL checking and indicate a new error "CRL path validation 859109998Smarkm error" in this case. Applications wanting additional details can use 860109998Smarkm the verify callback and check the new "parent" field. If this is not 861109998Smarkm NULL CRL path validation is taking place. Existing applications wont 862109998Smarkm see this because it requires extended CRL support which is off by 863109998Smarkm default. 864109998Smarkm 865109998Smarkm This work was sponsored by Google. 866109998Smarkm [Steve Henson] 867109998Smarkm 868109998Smarkm *) Support for freshest CRL extension. 869109998Smarkm 870109998Smarkm This work was sponsored by Google. 871109998Smarkm [Steve Henson] 872109998Smarkm 873109998Smarkm *) Initial indirect CRL support.

This 909109998Smarkm mechanism allows a numeric "hash" to be extracted from a thread ID in 910109998Smarkm either case, and on platforms where pointers are larger than 'long', 911109998Smarkm mixing is done to help ensure the numeric 'hash' is usable even if it 912109998Smarkm can't be guaranteed unique. The default mechanism is to use "&errno" 913109998Smarkm as a pointer-based thread ID to distinguish between threads. 914109998Smarkm 915109998Smarkm Applications that want to provide their own thread IDs should now use 916109998Smarkm CRYPTO_THREADID_set_callback() to register a callback that will call 917109998Smarkm either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer(). 918109998Smarkm 919109998Smarkm Note that ERR_remove_state() is now deprecated, because it is tied 920109998Smarkm to the assumption that thread IDs are numeric. ERR_remove_state(0) 921109998Smarkm to free the current thread's error state should be replaced by 922109998Smarkm ERR_remove_thread_state(NULL). 923109998Smarkm 924109998Smarkm (This new approach replaces the functions CRYPTO_set_idptr_callback(), 925109998Smarkm CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in 926109998Smarkm OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an 927109998Smarkm application was previously providing a numeric thread callback that 928109998Smarkm was inappropriate for distinguishing threads, then uniqueness might 929109998Smarkm have been obtained with &errno that happened immediately in the 930109998Smarkm intermediate development versions of OpenSSL; this is no longer the 931109998Smarkm case, the numeric thread callback will now override the automatic use 932109998Smarkm of &errno.) 933109998Smarkm [Geoff Thorpe, with help from Bodo Moeller] 934109998Smarkm 935109998Smarkm *) Initial support for different CRL issuing certificates.

Since this is not an 988109998Smarkm official specification yet and no extension type assignment by 989109998Smarkm IANA exists, this extension (for now) will have to be explicitly 990109998Smarkm enabled when building OpenSSL by providing the extension number 991109998Smarkm to use. For example, specify an option 992109998Smarkm 993109998Smarkm -DTLSEXT_TYPE_opaque_prf_input=0x9527 994109998Smarkm 995109998Smarkm to the "config" or "Configure" script to enable the extension, 996109998Smarkm assuming extension number 0x9527 (which is a completely arbitrary 997109998Smarkm and unofficial assignment based on the MD5 hash of the Internet 998109998Smarkm Draft). Note that by doing so, you potentially lose 999109998Smarkm interoperability with other TLS implementations since these might 1000109998Smarkm be using the same extension number for other purposes. 1001109998Smarkm 1002109998Smarkm SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the 1003109998Smarkm opaque PRF input value to use in the handshake. This will create 1004109998Smarkm an interal copy of the length-'len' string at 'src', and will 1005109998Smarkm return non-zero for success. 1006109998Smarkm 1007109998Smarkm To get more control and flexibility, provide a callback function 1008109998Smarkm by using 1009109998Smarkm 1010109998Smarkm SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb) 1011109998Smarkm SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg) 1012109998Smarkm 1013109998Smarkm where 1014109998Smarkm 1015109998Smarkm int (*cb)(SSL *, void *peerinput, size_t len, void *arg); 1016109998Smarkm void *arg; 1017109998Smarkm 1018109998Smarkm Callback function 'cb' will be called in handshakes, and is 1019109998Smarkm expected to use SSL_set_tlsext_opaque_prf_input() as appropriate. 1020109998Smarkm Argument 'arg' is for application purposes (the value as given to 1021109998Smarkm SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly 1022109998Smarkm be provided to the callback function). The callback function 1023109998Smarkm has to return non-zero to report success: usually 1 to use opaque 1024109998Smarkm PRF input just if possible, or 2 to enforce use of the opaque PRF 1025109998Smarkm input. In the latter case, the library will abort the handshake 1026109998Smarkm if opaque PRF input is not successfully negotiated. 1027109998Smarkm 1028109998Smarkm Arguments 'peerinput' and 'len' given to the callback function 1029109998Smarkm will always be NULL and 0 in the case of a client. A server will 1030109998Smarkm see the client's opaque PRF input through these variables if 1031109998Smarkm available (NULL and 0 otherwise). Note that if the server 1032109998Smarkm provides an opaque PRF input, the length must be the same as the 1033109998Smarkm length of the client's opaque PRF input. 1034109998Smarkm 1035109998Smarkm Note that the callback function will only be called when creating 1036109998Smarkm a new session (session resumption can resume whatever was 1037109998Smarkm previously negotiated), and will not be called in SSL 2.0 1038109998Smarkm handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or 1039109998Smarkm SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended 1040109998Smarkm for applications that need to enforce opaque PRF input. 1041109998Smarkm 1042109998Smarkm [Bodo Moeller] 1043109998Smarkm 1044109998Smarkm *) Update ssl code to support digests other than SHA1+MD5 for handshake 1045109998Smarkm MAC. 1046109998Smarkm 1047109998Smarkm [Victor B. Wagner <vitus@cryptocom.ru>] 1048109998Smarkm 1049109998Smarkm *) Add RFC4507 support to OpenSSL. This includes the corrections in 1050109998Smarkm RFC4507bis. The encrypted ticket format is an encrypted encoded 1051109998Smarkm SSL_SESSION structure, that way new session features are automatically 1052109998Smarkm supported. 1053109998Smarkm 1054109998Smarkm If a client application caches session in an SSL_SESSION structure 1055109998Smarkm support is transparent because tickets are now stored in the encoded 1056109998Smarkm SSL_SESSION. 1057109998Smarkm 1058109998Smarkm The SSL_CTX structure automatically generates keys for ticket 1059109998Smarkm protection in servers so again support should be possible 1060109998Smarkm with no application modification. 1061109998Smarkm 1062109998Smarkm If a client or server wishes to disable RFC4507 support then the option 1063109998Smarkm SSL_OP_NO_TICKET can be set. 1064109998Smarkm 1065109998Smarkm Add a TLS extension debugging callback to allow the contents of any client 1066109998Smarkm or server extensions to be examined. 1067109998Smarkm 1068109998Smarkm This work was sponsored by Google. 1069109998Smarkm [Steve Henson] 1070109998Smarkm 1071109998Smarkm *) Final changes to avoid use of pointer pointer casts in OpenSSL. 1072109998Smarkm OpenSSL should now compile cleanly on gcc 4.2 1073109998Smarkm [Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson] 1074109998Smarkm 1075109998Smarkm *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC 1076109998Smarkm support including streaming MAC support: this is required for GOST 1077109998Smarkm ciphersuite support. 1078109998Smarkm [Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson] 1079109998Smarkm 1080109998Smarkm *) Add option -stream to use PKCS#7 streaming in smime utility. New 1081109998Smarkm function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream() 1082109998Smarkm to output in BER and PEM format. 1083109998Smarkm [Steve Henson] 1084109998Smarkm 1085109998Smarkm *) Experimental support for use of HMAC via EVP_PKEY interface. This 1086109998Smarkm allows HMAC to be handled via the EVP_DigestSign*() interface. The 1087109998Smarkm EVP_PKEY "key" in this case is the HMAC key, potentially allowing 1088109998Smarkm ENGINE support for HMAC keys which are unextractable. New -mac and 1089109998Smarkm -macopt options to dgst utility. 1090109998Smarkm [Steve Henson] 1091109998Smarkm 1092109998Smarkm *) New option -sigopt to dgst utility. Update dgst to use 1093109998Smarkm EVP_Digest{Sign,Verify}*. These two changes make it possible to use 1094109998Smarkm alternative signing paramaters such as X9.31 or PSS in the dgst 1095109998Smarkm utility. 1096109998Smarkm [Steve Henson] 1097109998Smarkm 1098109998Smarkm *) Change ssl_cipher_apply_rule(), the internal function that does 1099109998Smarkm the work each time a ciphersuite string requests enabling 1100109998Smarkm ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or 1101109998Smarkm removing ("!foo+bar") a class of ciphersuites: Now it maintains 1102109998Smarkm the order of disabled ciphersuites such that those ciphersuites 1103109998Smarkm that most recently went from enabled to disabled not only stay 1104109998Smarkm in order with respect to each other, but also have higher priority 1105109998Smarkm than other disabled ciphersuites the next time ciphersuites are 1106109998Smarkm enabled again. 1107109998Smarkm 1108109998Smarkm This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable 1109109998Smarkm the same ciphersuites as with "HIGH" alone, but in a specific 1110109998Smarkm order where the PSK ciphersuites come first (since they are the 1111109998Smarkm most recently disabled ciphersuites when "HIGH" is parsed). 1112109998Smarkm 1113109998Smarkm Also, change ssl_create_cipher_list() (using this new 1114109998Smarkm funcionality) such that between otherwise identical 1115109998Smarkm cihpersuites, ephemeral ECDH is preferred over ephemeral DH in 1116109998Smarkm the default order. 1117109998Smarkm [Bodo Moeller] 1118109998Smarkm 1119109998Smarkm *) Change ssl_create_cipher_list() so that it automatically 1120109998Smarkm arranges the ciphersuites in reasonable order before starting 1121109998Smarkm to process the rule string. Thus, the definition for "DEFAULT" 1122109998Smarkm (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but 1123109998Smarkm remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". 1124109998Smarkm This makes it much easier to arrive at a reasonable default order 1125109998Smarkm in applications for which anonymous ciphers are OK (meaning 1126109998Smarkm that you can't actually use DEFAULT). 1127109998Smarkm [Bodo Moeller; suggested by Victor Duchovni] 1128109998Smarkm 1129109998Smarkm *) Split the SSL/TLS algorithm mask (as used for ciphersuite string 1130109998Smarkm processing) into multiple integers instead of setting 1131109998Smarkm "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", 1132109998Smarkm "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. 1133109998Smarkm (These masks as well as the individual bit definitions are hidden 1134109998Smarkm away into the non-exported interface ssl/ssl_locl.h, so this 1135109998Smarkm change to the definition of the SSL_CIPHER structure shouldn't 1136109998Smarkm affect applications.) This give us more bits for each of these 1137109998Smarkm categories, so there is no longer a need to coagulate AES128 and 1138109998Smarkm AES256 into a single algorithm bit, and to coagulate Camellia128 1139109998Smarkm and Camellia256 into a single algorithm bit, which has led to all 1140109998Smarkm kinds of kludges. 1141109998Smarkm 1142109998Smarkm Thus, among other things, the kludge introduced in 0.9.7m and 1143109998Smarkm 0.9.8e for masking out AES256 independently of AES128 or masking 1144109998Smarkm out Camellia256 independently of AES256 is not needed here in 0.9.9. 1145109998Smarkm 1146109998Smarkm With the change, we also introduce new ciphersuite aliases that 1147109998Smarkm so far were missing: "AES128", "AES256", "CAMELLIA128", and 1148109998Smarkm "CAMELLIA256". 1149109998Smarkm [Bodo Moeller] 1150109998Smarkm 1151109998Smarkm *) Add support for dsa-with-SHA224 and dsa-with-SHA256. 1152109998Smarkm Use the leftmost N bytes of the signature input if the input is 1153109998Smarkm larger than the prime q (with N being the size in bytes of q). 1154109998Smarkm [Nils Larsch] 1155109998Smarkm 1156109998Smarkm *) Very *very* experimental PKCS#7 streaming encoder support.

Safestack is 1165109998Smarkm reimplemented. Update ASN1 to avoid use of legacy functions. 1166109998Smarkm [Steve Henson] 1167109998Smarkm 1168109998Smarkm *) Win32/64 targets are linked with Winsock2. 1169109998Smarkm [Andy Polyakov] 1170109998Smarkm 1171109998Smarkm *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected 1172109998Smarkm to external functions. This can be used to increase CRL handling 1173109998Smarkm efficiency especially when CRLs are very large by (for example) storing 1174109998Smarkm the CRL revoked certificates in a database. 1175109998Smarkm [Steve Henson] 1176109998Smarkm 1177109998Smarkm *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so 1178109998Smarkm new CRLs added to a directory can be used. New command line option 1179109998Smarkm -verify_return_error to s_client and s_server. This causes real errors 1180109998Smarkm to be returned by the verify callback instead of carrying on no matter 1181109998Smarkm what. This reflects the way a "real world" verify callback would behave. 1182109998Smarkm [Steve Henson] 1183109998Smarkm 1184109998Smarkm *) GOST engine, supporting several GOST algorithms and public key formats. 1185109998Smarkm Kindly donated by Cryptocom. 1186109998Smarkm [Cryptocom] 1187109998Smarkm 1188109998Smarkm *) Partial support for Issuing Distribution Point CRL extension. CRLs 1189109998Smarkm partitioned by DP are handled but no indirect CRL or reason partitioning 1190109998Smarkm (yet). Complete overhaul of CRL handling: now the most suitable CRL is 1191109998Smarkm selected via a scoring technique which handles IDP and AKID in CRLs. 1192109998Smarkm [Steve Henson] 1193109998Smarkm 1194109998Smarkm *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which 1195109998Smarkm will ultimately be used for all verify operations: this will remove the 1196109998Smarkm X509_STORE dependency on certificate verification and allow alternative 1197109998Smarkm lookup methods. X509_STORE based implementations of these two callbacks. 1198109998Smarkm [Steve Henson] 1199109998Smarkm 1200109998Smarkm *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. 1201109998Smarkm Modify get_crl() to find a valid (unexpired) CRL if possible. 1202109998Smarkm [Steve Henson] 1203109998Smarkm 1204109998Smarkm *) New function X509_CRL_match() to check if two CRLs are identical. Normally 1205109998Smarkm this would be called X509_CRL_cmp() but that name is already used by 1206109998Smarkm a function that just compares CRL issuer names. Cache several CRL 1207109998Smarkm extensions in X509_CRL structure and cache CRLDP in X509. 1208109998Smarkm [Steve Henson] 1209109998Smarkm 1210109998Smarkm *) Store a "canonical" representation of X509_NAME structure (ASN1 Name) 1211109998Smarkm this maps equivalent X509_NAME structures into a consistent structure. 1212109998Smarkm Name comparison can then be performed rapidly using memcmp(). 1213109998Smarkm [Steve Henson] 1214109998Smarkm 1215109998Smarkm *) Non-blocking OCSP request processing. Add -timeout option to ocsp 1216109998Smarkm utility. 1217109998Smarkm [Steve Henson] 1218109998Smarkm 1219109998Smarkm *) Allow digests to supply their own micalg string for S/MIME type using 1220109998Smarkm the ctrl EVP_MD_CTRL_MICALG. 1221109998Smarkm [Steve Henson] 1222109998Smarkm 1223109998Smarkm *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the 1224109998Smarkm EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN 1225109998Smarkm ctrl. It can then customise the structure before and/or after signing 1226109998Smarkm if necessary. 1227109998Smarkm [Steve Henson] 1228109998Smarkm 1229109998Smarkm *) New function OBJ_add_sigid() to allow application defined signature OIDs 1230109998Smarkm to be added to OpenSSLs internal tables. New function OBJ_sigid_free() 1231109998Smarkm to free up any added signature OIDs. 1232109998Smarkm [Steve Henson] 1233109998Smarkm 1234109998Smarkm *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(), 1235109998Smarkm EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal 1236109998Smarkm digest and cipher tables. New options added to openssl utility: 1237109998Smarkm list-message-digest-algorithms and list-cipher-algorithms. 1238109998Smarkm [Steve Henson] 1239109998Smarkm 1240109998Smarkm *) Change the array representation of binary polynomials: the list 1241109998Smarkm of degrees of non-zero coefficients is now terminated with -1. 1242109998Smarkm Previously it was terminated with 0, which was also part of the 1243109998Smarkm value; thus, the array representation was not applicable to 1244109998Smarkm polynomials where t^0 has coefficient zero. This change makes 1245109998Smarkm the array representation useful in a more general context. 1246109998Smarkm [Douglas Stebila] 1247109998Smarkm 1248109998Smarkm *) Various modifications and fixes to SSL/TLS cipher string 1249109998Smarkm handling. For ECC, the code now distinguishes between fixed ECDH 1250109998Smarkm with RSA certificates on the one hand and with ECDSA certificates 1251109998Smarkm on the other hand, since these are separate ciphersuites. The 1252109998Smarkm unused code for Fortezza ciphersuites has been removed. 1253109998Smarkm 1254109998Smarkm For consistency with EDH, ephemeral ECDH is now called "EECDH" 1255109998Smarkm (not "ECDHE"). For consistency with the code for DH 1256109998Smarkm certificates, use of ECDH certificates is now considered ECDH 1257109998Smarkm authentication, not RSA or ECDSA authentication (the latter is 1258109998Smarkm merely the CA's signing algorithm and not actively used in the 1259109998Smarkm protocol). 1260109998Smarkm 1261109998Smarkm The temporary ciphersuite alias "ECCdraft" is no longer 1262109998Smarkm available, and ECC ciphersuites are no longer excluded from "ALL" 1263109998Smarkm and "DEFAULT". The following aliases now exist for RFC 4492 1264109998Smarkm ciphersuites, most of these by analogy with the DH case: 1265109998Smarkm 1266109998Smarkm kECDHr - ECDH cert, signed with RSA 1267109998Smarkm kECDHe - ECDH cert, signed with ECDSA 1268109998Smarkm kECDH - ECDH cert (signed with either RSA or ECDSA) 1269109998Smarkm kEECDH - ephemeral ECDH 1270109998Smarkm ECDH - ECDH cert or ephemeral ECDH 1271109998Smarkm 1272109998Smarkm aECDH - ECDH cert 1273109998Smarkm aECDSA - ECDSA cert 1274109998Smarkm ECDSA - ECDSA cert 1275109998Smarkm 1276109998Smarkm AECDH - anonymous ECDH 1277109998Smarkm EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") 1278109998Smarkm 1279109998Smarkm [Bodo Moeller] 1280109998Smarkm 1281109998Smarkm *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. 1282109998Smarkm Use correct micalg parameters depending on digest(s) in signed message. 1283109998Smarkm [Steve Henson] 1284109998Smarkm 1285109998Smarkm *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process 1286109998Smarkm an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. 1287109998Smarkm [Steve Henson] 1288109998Smarkm 1289109998Smarkm *) Initial engine support for EVP_PKEY_METHOD. New functions to permit 1290109998Smarkm an engine to register a method. Add ENGINE lookups for methods and 1291109998Smarkm functional reference processing. 1292109998Smarkm [Steve Henson] 1293109998Smarkm 1294109998Smarkm *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of 1295109998Smarkm EVP_{Sign,Verify}* which allow an application to customise the signature 1296109998Smarkm process. 1297109998Smarkm [Steve Henson] 1298109998Smarkm 1299109998Smarkm *) New -resign option to smime utility. This adds one or more signers 1300109998Smarkm to an existing PKCS#7 signedData structure. Also -md option to use an 1301109998Smarkm alternative message digest algorithm for signing. 1302109998Smarkm [Steve Henson] 1303109998Smarkm 1304109998Smarkm *) Tidy up PKCS#7 routines and add new functions to make it easier to 1305109998Smarkm create PKCS7 structures containing multiple signers. Update smime 1306109998Smarkm application to support multiple signers. 1307109998Smarkm [Steve Henson] 1308109998Smarkm 1309109998Smarkm *) New -macalg option to pkcs12 utility to allow setting of an alternative 1310109998Smarkm digest MAC. 1311109998Smarkm [Steve Henson] 1312109998Smarkm 1313109998Smarkm *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. 1314109998Smarkm Reorganize PBE internals to lookup from a static table using NIDs, 1315109998Smarkm add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: 1316109998Smarkm EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative 1317109998Smarkm PRF which will be automatically used with PBES2. 1318109998Smarkm [Steve Henson] 1319109998Smarkm 1320109998Smarkm *) Replace the algorithm specific calls to generate keys in "req" with the 1321109998Smarkm new API. 1322109998Smarkm [Steve Henson] 1323109998Smarkm 1324109998Smarkm *) Update PKCS#7 enveloped data routines to use new API. This is now 1325109998Smarkm supported by any public key method supporting the encrypt operation. A 1326109998Smarkm ctrl is added to allow the public key algorithm to examine or modify 1327109998Smarkm the PKCS#7 RecipientInfo structure if it needs to: for RSA this is 1328109998Smarkm a no op. 1329109998Smarkm [Steve Henson] 1330109998Smarkm 1331109998Smarkm *) Add a ctrl to asn1 method to allow a public key algorithm to express 1332109998Smarkm a default digest type to use. In most cases this will be SHA1 but some 1333109998Smarkm algorithms (such as GOST) need to specify an alternative digest. The 1334109998Smarkm return value indicates how strong the prefernce is 1 means optional and 1335109998Smarkm 2 is mandatory (that is it is the only supported type). Modify 1336109998Smarkm ASN1_item_sign() to accept a NULL digest argument to indicate it should 1337109998Smarkm use the default md. Update openssl utilities to use the default digest 1338109998Smarkm type for signing if it is not explicitly indicated. 1339109998Smarkm [Steve Henson] 1340109998Smarkm 1341109998Smarkm *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New 1342109998Smarkm EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant 1343109998Smarkm signing method from the key type. This effectively removes the link 1344109998Smarkm between digests and public key types. 1345109998Smarkm [Steve Henson] 1346109998Smarkm 1347109998Smarkm *) Add an OID cross reference table and utility functions. Its purpose is to 1348109998Smarkm translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, 1349109998Smarkm rsaEncryption. This will allow some of the algorithm specific hackery 1350109998Smarkm needed to use the correct OID to be removed. 1351109998Smarkm [Steve Henson] 1352109998Smarkm 1353109998Smarkm *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO 1354109998Smarkm structures for PKCS7_sign(). They are now set up by the relevant public 1355109998Smarkm key ASN1 method. 1356109998Smarkm [Steve Henson] 1357109998Smarkm 1358109998Smarkm *) Add provisional EC pkey method with support for ECDSA and ECDH. 1359109998Smarkm [Steve Henson] 1360109998Smarkm 1361109998Smarkm *) Add support for key derivation (agreement) in the API, DH method and 1362109998Smarkm pkeyutl. 1363109998Smarkm [Steve Henson] 1364109998Smarkm 1365109998Smarkm *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support 1366109998Smarkm public and private key formats. As a side effect these add additional 1367109998Smarkm command line functionality not previously available: DSA signatures can be 1368109998Smarkm generated and verified using pkeyutl and DH key support and generation in 1369109998Smarkm pkey, genpkey. 1370109998Smarkm [Steve Henson] 1371109998Smarkm 1372109998Smarkm *) BeOS support. 1373109998Smarkm [Oliver Tappe <zooey@hirschkaefer.de>] 1374109998Smarkm 1375109998Smarkm *) New make target "install_html_docs" installs HTML renditions of the 1376109998Smarkm manual pages. 1377109998Smarkm [Oliver Tappe <zooey@hirschkaefer.de>] 1378109998Smarkm 1379109998Smarkm *) New utility "genpkey" this is analagous to "genrsa" etc except it can 1380109998Smarkm generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to 1381109998Smarkm support key and parameter generation and add initial key generation 1382109998Smarkm functionality for RSA. 1383109998Smarkm [Steve Henson] 1384109998Smarkm 1385109998Smarkm *) Add functions for main EVP_PKEY_method operations. The undocumented 1386109998Smarkm functions EVP_PKEY_{encrypt,decrypt} have been renamed to 1387109998Smarkm EVP_PKEY_{encrypt,decrypt}_old. 1388109998Smarkm [Steve Henson] 1389109998Smarkm 1390109998Smarkm *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public 1391109998Smarkm key API, doesn't do much yet. 1392109998Smarkm [Steve Henson] 1393109998Smarkm 1394109998Smarkm *) New function EVP_PKEY_asn1_get0_info() to retrieve information about 1395109998Smarkm public key algorithms. New option to openssl utility: 1396109998Smarkm "list-public-key-algorithms" to print out info. 1397109998Smarkm [Steve Henson] 1398109998Smarkm 1399109998Smarkm *) Implement the Supported Elliptic Curves Extension for 1400109998Smarkm ECC ciphersuites from draft-ietf-tls-ecc-12.txt. 1401109998Smarkm [Douglas Stebila] 1402109998Smarkm 1403109998Smarkm *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or 1404109998Smarkm EVP_CIPHER structures to avoid later problems in EVP_cleanup(). 1405109998Smarkm [Steve Henson] 1406109998Smarkm 1407109998Smarkm *) New utilities pkey and pkeyparam. These are similar to algorithm specific 1408109998Smarkm utilities such as rsa, dsa, dsaparam etc except they process any key 1409109998Smarkm type. 1410109998Smarkm [Steve Henson] 1411109998Smarkm 1412109998Smarkm *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New 1413109998Smarkm functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), 1414109998Smarkm EVP_PKEY_print_param() to print public key data from an EVP_PKEY 1415109998Smarkm structure. 1416109998Smarkm [Steve Henson] 1417109998Smarkm 1418109998Smarkm *) Initial support for pluggable public key ASN1. 1419109998Smarkm De-spaghettify the public key ASN1 handling. Move public and private 1420109998Smarkm key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate 1421109998Smarkm algorithm specific handling to a single module within the relevant 1422109998Smarkm algorithm directory. Add functions to allow (near) opaque processing 1423109998Smarkm of public and private key structures. 1424109998Smarkm [Steve Henson] 1425109998Smarkm 1426109998Smarkm *) Implement the Supported Point Formats Extension for 1427109998Smarkm ECC ciphersuites from draft-ietf-tls-ecc-12.txt. 1428109998Smarkm [Douglas Stebila] 1429109998Smarkm 1430109998Smarkm *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members 1431109998Smarkm for the psk identity [hint] and the psk callback functions to the 1432109998Smarkm SSL_SESSION, SSL and SSL_CTX structure. 1433109998Smarkm 1434109998Smarkm New ciphersuites: 1435109998Smarkm PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, 1436109998Smarkm PSK-AES256-CBC-SHA 1437109998Smarkm 1438109998Smarkm New functions: 1439109998Smarkm SSL_CTX_use_psk_identity_hint 1440109998Smarkm SSL_get_psk_identity_hint 1441109998Smarkm SSL_get_psk_identity 1442109998Smarkm SSL_use_psk_identity_hint 1443109998Smarkm 1444109998Smarkm [Mika Kousa and Pasi Eronen of Nokia Corporation] 1445109998Smarkm 1446109998Smarkm *) Add RFC 3161 compliant time stamp request creation, response generation 1447109998Smarkm and response verification functionality. 1448109998Smarkm [Zolt�n Gl�zik <zglozik@opentsa.org>, The OpenTSA Project] 1449109998Smarkm 1450109998Smarkm *) Add initial support for TLS extensions, specifically for the server_name 1451109998Smarkm extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now 1452109998Smarkm have new members for a host name. The SSL data structure has an 1453109998Smarkm additional member SSL_CTX *initial_ctx so that new sessions can be 1454109998Smarkm stored in that context to allow for session resumption, even after the 1455109998Smarkm SSL has been switched to a new SSL_CTX in reaction to a client's 1456109998Smarkm server_name extension. 1457109998Smarkm 1458109998Smarkm New functions (subject to change): 1459109998Smarkm 1460109998Smarkm SSL_get_servername() 1461109998Smarkm SSL_get_servername_type() 1462109998Smarkm SSL_set_SSL_CTX() 1463109998Smarkm 1464109998Smarkm New CTRL codes and macros (subject to change): 1465109998Smarkm 1466109998Smarkm SSL_CTRL_SET_TLSEXT_SERVERNAME_CB 1467109998Smarkm - SSL_CTX_set_tlsext_servername_callback() 1468109998Smarkm SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG 1469109998Smarkm - SSL_CTX_set_tlsext_servername_arg() 1470109998Smarkm SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() 1471109998Smarkm 1472109998Smarkm openssl s_client has a new '-servername ...' option. 1473109998Smarkm 1474109998Smarkm openssl s_server has new options '-servername_host ...', '-cert2 ...', 1475109998Smarkm '-key2 ...', '-servername_fatal' (subject to change). This allows 1476109998Smarkm testing the HostName extension for a specific single host name ('-cert' 1477109998Smarkm and '-key' remain fallbacks for handshakes without HostName 1478109998Smarkm negotiation). If the unrecogninzed_name alert has to be sent, this by 1479109998Smarkm default is a warning; it becomes fatal with the '-servername_fatal' 1480109998Smarkm option. 1481109998Smarkm 1482109998Smarkm [Peter Sylvester, Remy Allais, Christophe Renou] 1483109998Smarkm 1484109998Smarkm *) Whirlpool hash implementation is added. 1485109998Smarkm [Andy Polyakov] 1486109998Smarkm 1487109998Smarkm *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to 1488109998Smarkm bn(64,32). Because of instruction set limitations it doesn't have 1489109998Smarkm any negative impact on performance. This was done mostly in order 1490109998Smarkm to make it possible to share assembler modules, such as bn_mul_mont 1491109998Smarkm implementations, between 32- and 64-bit builds without hassle. 1492109998Smarkm [Andy Polyakov] 1493109998Smarkm 1494109998Smarkm *) Move code previously exiled into file crypto/ec/ec2_smpt.c 1495109998Smarkm to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP 1496109998Smarkm macro. 1497109998Smarkm [Bodo Moeller] 1498109998Smarkm 1499109998Smarkm *) New candidate for BIGNUM assembler implementation, bn_mul_mont, 1500109998Smarkm dedicated Montgomery multiplication procedure, is introduced. 1501109998Smarkm BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher 1502109998Smarkm "64-bit" performance on certain 32-bit targets. 1503109998Smarkm [Andy Polyakov] 1504109998Smarkm 1505109998Smarkm *) New option SSL_OP_NO_COMP to disable use of compression selectively 1506109998Smarkm in SSL structures. New SSL ctrl to set maximum send fragment size. 1507109998Smarkm Save memory by seeting the I/O buffer sizes dynamically instead of 1508109998Smarkm using the maximum available value. 1509109998Smarkm [Steve Henson] 1510109998Smarkm 1511109998Smarkm *) New option -V for 'openssl ciphers'. This prints the ciphersuite code 1512109998Smarkm in addition to the text details. 1513109998Smarkm [Bodo Moeller] 1514109998Smarkm 1515109998Smarkm *) Very, very preliminary EXPERIMENTAL support for printing of general 1516109998Smarkm ASN1 structures. This currently produces rather ugly output and doesn't 1517109998Smarkm handle several customised structures at all. 1518109998Smarkm [Steve Henson] 1519109998Smarkm 1520109998Smarkm *) Integrated support for PVK file format and some related formats such 1521109998Smarkm as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support 1522109998Smarkm these in the 'rsa' and 'dsa' utilities. 1523109998Smarkm [Steve Henson] 1524109998Smarkm 1525109998Smarkm *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. 1526109998Smarkm [Steve Henson] 1527109998Smarkm 1528109998Smarkm *) Remove the ancient ASN1_METHOD code. This was only ever used in one 1529109998Smarkm place for the (very old) "NETSCAPE" format certificates which are now 1530109998Smarkm handled using new ASN1 code equivalents. 1531109998Smarkm [Steve Henson] 1532109998Smarkm 1533109998Smarkm *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD 1534109998Smarkm pointer and make the SSL_METHOD parameter in SSL_CTX_new, 1535109998Smarkm SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. 1536109998Smarkm [Nils Larsch] 1537109998Smarkm 1538109998Smarkm *) Modify CRL distribution points extension code to print out previously 1539109998Smarkm unsupported fields.

Seifert, "New Branch Prediction Vulnerabilities in OpenSSL 235579998Skris and Necessary Software Countermeasures"). The core of the change 235679998Skris are new versions BN_div_no_branch() and 235779998Skris BN_mod_inverse_no_branch() of BN_div() and BN_mod_inverse(), 235879998Skris respectively, which are slower, but avoid the security-relevant 235979998Skris conditional branches. These are automatically called by BN_div() 236079998Skris and BN_mod_inverse() if the flag BN_FLG_CONSTTIME is set for one 236179998Skris of the input BIGNUMs. Also, BN_is_bit_set() has been changed to 236279998Skris remove a conditional branch. 236379998Skris 236479998Skris BN_FLG_CONSTTIME is the new name for the previous 236579998Skris BN_FLG_EXP_CONSTTIME flag, since it now affects more than just 236679998Skris modular exponentiation. (Since OpenSSL 0.9.7h, setting this flag 236779998Skris in the exponent causes BN_mod_exp_mont() to use the alternative 236879998Skris implementation in BN_mod_exp_mont_consttime().) The old name 236979998Skris remains as a deprecated alias. 237079998Skris 237179998Skris Similary, RSA_FLAG_NO_EXP_CONSTTIME is replaced by a more general 237279998Skris RSA_FLAG_NO_CONSTTIME flag since the RSA implementation now uses 237379998Skris constant-time implementations for more than just exponentiation. 237479998Skris Here too the old name is kept as a deprecated alias. 237579998Skris 237679998Skris BN_BLINDING_new() will now use BN_dup() for the modulus so that 237779998Skris the BN_BLINDING structure gets an independent copy of the 237879998Skris modulus. This means that the previous "BIGNUM *m" argument to 237989837Skris BN_BLINDING_new() and to BN_BLINDING_create_param() now 238079998Skris essentially becomes "const BIGNUM *m", although we can't actually 238179998Skris change this in the header file before 0.9.9. It allows 238279998Skris RSA_setup_blinding() to use BN_with_flags() on the modulus to 238379998Skris enable BN_FLG_CONSTTIME. 238479998Skris 238579998Skris [Matthew D Wood (Intel Corp)] 238679998Skris 238779998Skris *) In the SSL/TLS server implementation, be strict about session ID 238879998Skris context matching (which matters if an application uses a single 238979998Skris external cache for different purposes).

The engines will accept the corrected or legacy ids 265072613Skris ('ncipher' and '4758_cca' respectively) when binding. NB, 265172613Skris this only applies when building 'shared'. 265272613Skris [Corinna Vinschen <vinschen@redhat.com> and Geoff Thorpe] 265372613Skris 265472613Skris *) Add attribute functions to EVP_PKEY structure. Modify 265572613Skris PKCS12_create() to recognize a CSP name attribute and 265672613Skris use it. Make -CSP option work again in pkcs12 utility. 265772613Skris [Steve Henson] 265872613Skris 265972613Skris *) Add new functionality to the bn blinding code: 266072613Skris - automatic re-creation of the BN_BLINDING parameters after 266172613Skris a fixed number of uses (currently 32) 266272613Skris - add new function for parameter creation 266372613Skris - introduce flags to control the update behaviour of the 266472613Skris BN_BLINDING parameters 266572613Skris - hide BN_BLINDING structure 266672613Skris Add a second BN_BLINDING slot to the RSA structure to improve 266772613Skris performance when a single RSA object is shared among several 266872613Skris threads. 266972613Skris [Nils Larsch] 267072613Skris 267172613Skris *) Add support for DTLS. 267276866Skris [Nagendra Modadugu <nagendra@cs.stanford.edu> and Ben Laurie] 267376866Skris 267476866Skris *) Add support for DER encoded private keys (SSL_FILETYPE_ASN1) 267576866Skris to SSL_CTX_use_PrivateKey_file() and SSL_use_PrivateKey_file() 267676866Skris [Walter Goulet] 267776866Skris 267872613Skris *) Remove buggy and incompletet DH cert support from 267972613Skris ssl/ssl_rsa.c and ssl/s3_both.c 268072613Skris [Nils Larsch] 268172613Skris 268276866Skris *) Use SHA-1 instead of MD5 as the default digest algorithm for 268376866Skris the apps/openssl applications. 268476866Skris [Nils Larsch] 268576866Skris 268676866Skris *) Compile clean with "-Wall -Wmissing-prototypes 268776866Skris -Wstrict-prototypes -Wmissing-declarations -Werror". Currently 268872613Skris DEBUG_SAFESTACK must also be set. 268972613Skris [Ben Laurie] 269072613Skris 269176866Skris *) Change ./Configure so that certain algorithms can be disabled by default. 269276866Skris The new counterpiece to "no-xxx" is "enable-xxx". 269376866Skris 269476866Skris The patented RC5 and MDC2 algorithms will now be disabled unless 269576866Skris "enable-rc5" and "enable-mdc2", respectively, are specified. 269676866Skris 269776866Skris (IDEA remains enabled despite being patented. This is because IDEA 269876866Skris is frequently required for interoperability, and there is no license 269976866Skris fee for non-commercial use. As before, "no-idea" can be used to 270076866Skris avoid this algorithm.) 270176866Skris 270276866Skris [Bodo Moeller] 270376866Skris 270476866Skris *) Add processing of proxy certificates (see RFC 3820). This work was 270576866Skris sponsored by KTH (The Royal Institute of Technology in Stockholm) and 270672613Skris EGEE (Enabling Grids for E-science in Europe). 270772613Skris [Richard Levitte] 270872613Skris 270972613Skris *) RC4 performance overhaul on modern architectures/implementations, such 271072613Skris as Intel P4, IA-64 and AMD64. 271172613Skris [Andy Polyakov] 271272613Skris 271372613Skris *) New utility extract-section.pl. This can be used specify an alternative 271472613Skris section number in a pod file instead of having to treat each file as 271572613Skris a separate case in Makefile. This can be done by adding two lines to the 271672613Skris pod file: 271772613Skris 271872613Skris =for comment openssl_section:XXX 271972613Skris 272072613Skris The blank line is mandatory. 272172613Skris 272268651Skris [Steve Henson] 272368651Skris 272468651Skris *) New arguments -certform, -keyform and -pass for s_client and s_server 272568651Skris to allow alternative format key and certificate files and passphrase 272668651Skris sources. 272768651Skris [Steve Henson] 272868651Skris 272968651Skris *) New structure X509_VERIFY_PARAM which combines current verify parameters, 273068651Skris update associated structures and add various utility functions. 273168651Skris 273268651Skris Add new policy related verify parameters, include policy checking in 273368651Skris standard verify code. Enhance 'smime' application with extra parameters 273468651Skris to support policy checking and print out. 273568651Skris [Steve Henson] 273668651Skris 273768651Skris *) Add a new engine to support VIA PadLock ACE extensions in the VIA C3 273868651Skris Nehemiah processors. These extensions support AES encryption in hardware 273968651Skris as well as RNG (though RNG support is currently disabled). 274068651Skris [Michal Ludvig <michal@logix.cz>, with help from Andy Polyakov] 274168651Skris 274268651Skris *) Deprecate BN_[get|set]_params() functions (they were ignored internally). 274368651Skris [Geoff Thorpe] 274468651Skris 274568651Skris *) New FIPS 180-2 algorithms, SHA-224/-256/-384/-512 are implemented. 274668651Skris [Andy Polyakov and a number of other people] 274768651Skris 274868651Skris *) Improved PowerPC platform support. Most notably BIGNUM assembler 274968651Skris implementation contributed by IBM. 275068651Skris [Suresh Chari, Peter Waltenberg, Andy Polyakov] 275168651Skris 275268651Skris *) The new 'RSA_generate_key_ex' function now takes a BIGNUM for the public 275368651Skris exponent rather than 'unsigned long'. There is a corresponding change to 275468651Skris the new 'rsa_keygen' element of the RSA_METHOD structure. 275568651Skris [Jelte Jansen, Geoff Thorpe] 275668651Skris 275768651Skris *) Functionality for creating the initial serial number file is now 275868651Skris moved from CA.pl to the 'ca' utility with a new option -create_serial. 275968651Skris 276068651Skris (Before OpenSSL 0.9.7e, CA.pl used to initialize the serial 276168651Skris number file to 1, which is bound to cause problems. To avoid 276268651Skris the problems while respecting compatibility between different 0.9.7 276368651Skris patchlevels, 0.9.7e employed 'openssl x509 -next_serial' in 276468651Skris CA.pl for serial number initialization. With the new release 0.9.8, 276568651Skris we can fix the problem directly in the 'ca' utility.) 276668651Skris [Steve Henson] 276768651Skris 276868651Skris *) Reduced header interdepencies by declaring more opaque objects in 276968651Skris ossl_typ.h. As a consequence, including some headers (eg. engine.h) will 277068651Skris give fewer recursive includes, which could break lazy source code - so 277168651Skris this change is covered by the OPENSSL_NO_DEPRECATED symbol. As always, 277268651Skris developers should define this symbol when building and using openssl to 277368651Skris ensure they track the recommended behaviour, interfaces, [etc], but 277468651Skris backwards-compatible behaviour prevails when this isn't defined. 277568651Skris [Geoff Thorpe] 277668651Skris 277768651Skris *) New function X509_POLICY_NODE_print() which prints out policy nodes. 277868651Skris [Steve Henson] 277968651Skris 278068651Skris *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality. 278168651Skris This will generate a random key of the appropriate length based on the 278268651Skris cipher context. The EVP_CIPHER can provide its own random key generation 278368651Skris routine to support keys of a specific form. This is used in the des and 278468651Skris 3des routines to generate a key of the correct parity. Update S/MIME 278568651Skris code to use new functions and hence generate correct parity DES keys. 278668651Skris Add EVP_CHECK_DES_KEY #define to return an error if the key is not 278768651Skris valid (weak or incorrect parity). 278868651Skris [Steve Henson] 278968651Skris 279068651Skris *) Add a local set of CRLs that can be used by X509_verify_cert() as well 279168651Skris as looking them up. This is useful when the verified structure may contain 279268651Skris CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs 279368651Skris present unless the new PKCS7_NO_CRL flag is asserted. 279468651Skris [Steve Henson] 279568651Skris 279668651Skris *) Extend ASN1 oid configuration module. It now additionally accepts the 279768651Skris syntax: 279868651Skris 279968651Skris shortName = some long name, 1.2.3.4 280068651Skris [Steve Henson] 280168651Skris 280268651Skris *) Reimplemented the BN_CTX implementation. There is now no more static 280368651Skris limitation on the number of variables it can handle nor the depth of the 280468651Skris "stack" handling for BN_CTX_start()/BN_CTX_end() pairs. The stack 280568651Skris information can now expand as required, and rather than having a single 280668651Skris static array of bignums, BN_CTX now uses a linked-list of such arrays 280768651Skris allowing it to expand on demand whilst maintaining the usefulness of 280868651Skris BN_CTX's "bundling". 280968651Skris [Geoff Thorpe] 281068651Skris 281168651Skris *) Add a missing BN_CTX parameter to the 'rsa_mod_exp' callback in RSA_METHOD 281268651Skris to allow all RSA operations to function using a single BN_CTX. 281368651Skris [Geoff Thorpe] 281468651Skris 281568651Skris *) Preliminary support for certificate policy evaluation and checking. This 281668651Skris is initially intended to pass the tests outlined in "Conformance Testing 281768651Skris of Relying Party Client Certificate Path Processing Logic" v1.07. 281868651Skris [Steve Henson] 281968651Skris 282068651Skris *) bn_dup_expand() has been deprecated, it was introduced in 0.9.7 and 282168651Skris remained unused and not that useful. A variety of other little bignum 282268651Skris tweaks and fixes have also been made continuing on from the audit (see 282368651Skris below). 282468651Skris [Geoff Thorpe] 282568651Skris 282668651Skris *) Constify all or almost all d2i, c2i, s2i and r2i functions, along with 282768651Skris associated ASN1, EVP and SSL functions and old ASN1 macros. 282868651Skris [Richard Levitte] 282968651Skris 283068651Skris *) BN_zero() only needs to set 'top' and 'neg' to zero for correct results, 283168651Skris and this should never fail. So the return value from the use of 283268651Skris BN_set_word() (which can fail due to needless expansion) is now deprecated; 283368651Skris if OPENSSL_NO_DEPRECATED is defined, BN_zero() is a void macro. 283468651Skris [Geoff Thorpe] 283568651Skris 283668651Skris *) BN_CTX_get() should return zero-valued bignums, providing the same 283768651Skris initialised value as BN_new(). 283868651Skris [Geoff Thorpe, suggested by Ulf M�ller] 283968651Skris 284068651Skris *) Support for inhibitAnyPolicy certificate extension. 284168651Skris [Steve Henson] 284268651Skris 284368651Skris *) An audit of the BIGNUM code is underway, for which debugging code is 284468651Skris enabled when BN_DEBUG is defined. This makes stricter enforcements on what 284568651Skris is considered valid when processing BIGNUMs, and causes execution to 284668651Skris assert() when a problem is discovered. If BN_DEBUG_RAND is defined, 284768651Skris further steps are taken to deliberately pollute unused data in BIGNUM 284868651Skris structures to try and expose faulty code further on. For now, openssl will 284968651Skris (in its default mode of operation) continue to tolerate the inconsistent 285068651Skris forms that it has tolerated in the past, but authors and packagers should 285168651Skris consider trying openssl and their own applications when compiled with 285268651Skris these debugging symbols defined. It will help highlight potential bugs in 285368651Skris their own code, and will improve the test coverage for OpenSSL itself. At 285468651Skris some point, these tighter rules will become openssl's default to improve 285568651Skris maintainability, though the assert()s and other overheads will remain only 285668651Skris in debugging configurations. See bn.h for more details. 285768651Skris [Geoff Thorpe, Nils Larsch, Ulf M�ller] 285868651Skris 285968651Skris *) BN_CTX_init() has been deprecated, as BN_CTX is an opaque structure 286068651Skris that can only be obtained through BN_CTX_new() (which implicitly 286168651Skris initialises it). The presence of this function only made it possible 286268651Skris to overwrite an existing structure (and cause memory leaks). 286368651Skris [Geoff Thorpe] 286468651Skris 286568651Skris *) Because of the callback-based approach for implementing LHASH as a 286668651Skris template type, lh_insert() adds opaque objects to hash-tables and 286768651Skris lh_doall() or lh_doall_arg() are typically used with a destructor callback 286868651Skris to clean up those corresponding objects before destroying the hash table 286968651Skris (and losing the object pointers). So some over-zealous constifications in 287068651Skris LHASH have been relaxed so that lh_insert() does not take (nor store) the 287168651Skris objects as "const" and the lh_doall[_arg] callback wrappers are not 287268651Skris prototyped to have "const" restrictions on the object pointers they are 287368651Skris given (and so aren't required to cast them away any more). 287468651Skris [Geoff Thorpe] 287568651Skris 287668651Skris *) The tmdiff.h API was so ugly and minimal that our own timing utility 287768651Skris (speed) prefers to use its own implementation. The two implementations 287868651Skris haven't been consolidated as yet (volunteers?) but the tmdiff API has had 287968651Skris its object type properly exposed (MS_TM) instead of casting to/from "char 288068651Skris *". This may still change yet if someone realises MS_TM and "ms_time_***" 288168651Skris aren't necessarily the greatest nomenclatures - but this is what was used 288268651Skris internally to the implementation so I've used that for now. 288368651Skris [Geoff Thorpe] 288468651Skris 288568651Skris *) Ensure that deprecated functions do not get compiled when 288668651Skris OPENSSL_NO_DEPRECATED is defined. Some "openssl" subcommands and a few of 288768651Skris the self-tests were still using deprecated key-generation functions so 288868651Skris these have been updated also. 288968651Skris [Geoff Thorpe] 289068651Skris 289168651Skris *) Reorganise PKCS#7 code to separate the digest location functionality 289268651Skris into PKCS7_find_digest(), digest addtion into PKCS7_bio_add_digest(). 289368651Skris New function PKCS7_set_digest() to set the digest type for PKCS#7 289468651Skris digestedData type. Add additional code to correctly generate the 289568651Skris digestedData type and add support for this type in PKCS7 initialization 289668651Skris functions. 289768651Skris [Steve Henson] 289868651Skris 289968651Skris *) New function PKCS7_set0_type_other() this initializes a PKCS7 290068651Skris structure of type "other". 290168651Skris [Steve Henson] 290268651Skris 290368651Skris *) Fix prime generation loop in crypto/bn/bn_prime.pl by making 290468651Skris sure the loop does correctly stop and breaking ("division by zero") 290568651Skris modulus operations are not performed. The (pre-generated) prime 290668651Skris table crypto/bn/bn_prime.h was already correct, but it could not be 290768651Skris re-generated on some platforms because of the "division by zero" 290868651Skris situation in the script. 290968651Skris [Ralf S. Engelschall] 291068651Skris 291168651Skris *) Update support for ECC-based TLS ciphersuites according to 291268651Skris draft-ietf-tls-ecc-03.txt: the KDF1 key derivation function with 291368651Skris SHA-1 now is only used for "small" curves (where the 291468651Skris representation of a field element takes up to 24 bytes); for 291568651Skris larger curves, the field element resulting from ECDH is directly 291668651Skris used as premaster secret. 291768651Skris [Douglas Stebila (Sun Microsystems Laboratories)] 291868651Skris 291968651Skris *) Add code for kP+lQ timings to crypto/ec/ectest.c, and add SEC2 292068651Skris curve secp160r1 to the tests. 292168651Skris [Douglas Stebila (Sun Microsystems Laboratories)] 292268651Skris 292368651Skris *) Add the possibility to load symbols globally with DSO. 292468651Skris [G�tz Babin-Ebell <babin-ebell@trustcenter.de> via Richard Levitte] 292568651Skris 292668651Skris *) Add the functions ERR_set_mark() and ERR_pop_to_mark() for better 292768651Skris control of the error stack. 292868651Skris [Richard Levitte] 292968651Skris 293068651Skris *) Add support for STORE in ENGINE. 293168651Skris [Richard Levitte] 293268651Skris 293368651Skris *) Add the STORE type. The intention is to provide a common interface 293468651Skris to certificate and key stores, be they simple file-based stores, or 293568651Skris HSM-type store, or LDAP stores, or... 293668651Skris NOTE: The code is currently UNTESTED and isn't really used anywhere. 293768651Skris [Richard Levitte] 293868651Skris 293968651Skris *) Add a generic structure called OPENSSL_ITEM. This can be used to 294068651Skris pass a list of arguments to any function as well as provide a way 294168651Skris for a function to pass data back to the caller. 294268651Skris [Richard Levitte] 294368651Skris 294468651Skris *) Add the functions BUF_strndup() and BUF_memdup(). BUF_strndup() 294568651Skris works like BUF_strdup() but can be used to duplicate a portion of 294668651Skris a string. The copy gets NUL-terminated. BUF_memdup() duplicates 294768651Skris a memory area. 294868651Skris [Richard Levitte] 294968651Skris 295068651Skris *) Add the function sk_find_ex() which works like sk_find(), but will 295168651Skris return an index to an element even if an exact match couldn't be 295268651Skris found. The index is guaranteed to point at the element where the 295368651Skris searched-for key would be inserted to preserve sorting order. 295468651Skris [Richard Levitte] 295568651Skris 295668651Skris *) Add the function OBJ_bsearch_ex() which works like OBJ_bsearch() but 295768651Skris takes an extra flags argument for optional functionality. Currently, 295868651Skris the following flags are defined: 295968651Skris 296068651Skris OBJ_BSEARCH_VALUE_ON_NOMATCH 296168651Skris This one gets OBJ_bsearch_ex() to return a pointer to the first 296268651Skris element where the comparing function returns a negative or zero 296368651Skris number. 296468651Skris 296568651Skris OBJ_BSEARCH_FIRST_VALUE_ON_MATCH 296668651Skris This one gets OBJ_bsearch_ex() to return a pointer to the first 296768651Skris element where the comparing function returns zero. This is useful 296868651Skris if there are more than one element where the comparing function 296968651Skris returns zero. 297068651Skris [Richard Levitte] 297168651Skris 297268651Skris *) Make it possible to create self-signed certificates with 'openssl ca' 297368651Skris in such a way that the self-signed certificate becomes part of the 297468651Skris CA database and uses the same mechanisms for serial number generation 297568651Skris as all other certificate signing. The new flag '-selfsign' enables 297668651Skris this functionality. Adapt CA.sh and CA.pl.in. 297768651Skris [Richard Levitte] 297868651Skris 297968651Skris *) Add functionality to check the public key of a certificate request 298068651Skris against a given private. This is useful to check that a certificate 298168651Skris request can be signed by that key (self-signing). 298268651Skris [Richard Levitte] 298368651Skris 298468651Skris *) Make it possible to have multiple active certificates with the same 298568651Skris subject in the CA index file.

IPv6 addresses are now also displayed 304768651Skris correctly. 304868651Skris [Steve Henson] 304968651Skris 305068651Skris *) Added an ENGINE that implements RSA by performing private key 305168651Skris exponentiations with the GMP library. The conversions to and from 305268651Skris GMP's mpz_t format aren't optimised nor are any montgomery forms 305368651Skris cached, and on x86 it appears OpenSSL's own performance has caught up. 305468651Skris However there are likely to be other architectures where GMP could 305568651Skris provide a boost. This ENGINE is not built in by default, but it can be 305668651Skris specified at Configure time and should be accompanied by the necessary 305768651Skris linker additions, eg; 305868651Skris ./config -DOPENSSL_USE_GMP -lgmp 305968651Skris [Geoff Thorpe] 306068651Skris 306168651Skris *) "openssl engine" will not display ENGINE/DSO load failure errors when 306268651Skris testing availability of engines with "-t" - the old behaviour is 306368651Skris produced by increasing the feature's verbosity with "-tt". 306468651Skris [Geoff Thorpe] 306568651Skris 306668651Skris *) ECDSA routines: under certain error conditions uninitialized BN objects 306768651Skris could be freed.

The new API functions have "_ex" 308168651Skris postfixes and the older functions are reimplemented as wrappers for 308268651Skris the new ones. The OPENSSL_NO_DEPRECATED symbol can be used to hide 308368651Skris declarations of the old functions to help (graceful) attempts to 308468651Skris migrate to the new functions. Also, the new key-generation API 308568651Skris functions operate on a caller-supplied key-structure and return 308668651Skris success/failure rather than returning a key or NULL - this is to 308768651Skris help make "keygen" another member function of RSA_METHOD etc. 308868651Skris 308968651Skris Example for using the new callback interface: 309068651Skris 309168651Skris int (*my_callback)(int a, int b, BN_GENCB *cb) = ...; 309268651Skris void *my_arg = ...; 309368651Skris BN_GENCB my_cb; 309468651Skris 309568651Skris BN_GENCB_set(&my_cb, my_callback, my_arg); 309668651Skris 309768651Skris return BN_is_prime_ex(some_bignum, BN_prime_checks, NULL, &cb); 309868651Skris /* For the meaning of a, b in calls to my_callback(), see the 309968651Skris * documentation of the function that calls the callback. 310068651Skris * cb will point to my_cb; my_arg can be retrieved as cb->arg. 310168651Skris * my_callback should return 1 if it wants BN_is_prime_ex() 310268651Skris * to continue, or 0 to stop. 310368651Skris */ 310468651Skris 310568651Skris [Geoff Thorpe] 310668651Skris 310768651Skris *) Change the ZLIB compression method to be stateful, and make it 310868651Skris available to TLS with the number defined in 310968651Skris draft-ietf-tls-compression-04.txt. 311068651Skris [Richard Levitte] 311168651Skris 311268651Skris *) Add the ASN.1 structures and functions for CertificatePair, which 311368651Skris is defined as follows (according to X.509_4thEditionDraftV6.pdf): 311468651Skris 311568651Skris CertificatePair ::= SEQUENCE { 311668651Skris forward [0] Certificate OPTIONAL, 311768651Skris reverse [1] Certificate OPTIONAL, 311868651Skris -- at least one of the pair shall be present -- } 311968651Skris 312068651Skris Also implement the PEM functions to read and write certificate 312168651Skris pairs, and defined the PEM tag as "CERTIFICATE PAIR". 312268651Skris 312368651Skris This needed to be defined, mostly for the sake of the LDAP 312468651Skris attribute crossCertificatePair, but may prove useful elsewhere as 312568651Skris well. 312668651Skris [Richard Levitte] 312768651Skris 312868651Skris *) Make it possible to inhibit symlinking of shared libraries in 312968651Skris Makefile.shared, for Cygwin's sake. 313068651Skris [Richard Levitte] 313168651Skris 313268651Skris *) Extend the BIGNUM API by creating a function 313368651Skris void BN_set_negative(BIGNUM *a, int neg); 313468651Skris and a macro that behave like 313568651Skris int BN_is_negative(const BIGNUM *a); 313668651Skris 313768651Skris to avoid the need to access 'a->neg' directly in applications. 313868651Skris [Nils Larsch] 313968651Skris 314068651Skris *) Implement fast modular reduction for pseudo-Mersenne primes 314168651Skris used in NIST curves (crypto/bn/bn_nist.c, crypto/ec/ecp_nist.c). 314268651Skris EC_GROUP_new_curve_GFp() will now automatically use this 314368651Skris if applicable. 314468651Skris [Nils Larsch <nla@trustcenter.de>] 314568651Skris 314668651Skris *) Add new lock type (CRYPTO_LOCK_BN). 314768651Skris [Bodo Moeller] 314868651Skris 314968651Skris *) Change the ENGINE framework to automatically load engines 315068651Skris dynamically from specific directories unless they could be 315168651Skris found to already be built in or loaded. Move all the 315268651Skris current engines except for the cryptodev one to a new 315368651Skris directory engines/. 315468651Skris The engines in engines/ are built as shared libraries if 315568651Skris the "shared" options was given to ./Configure or ./config. 315668651Skris Otherwise, they are inserted in libcrypto.a. 315768651Skris /usr/local/ssl/engines is the default directory for dynamic 315868651Skris engines, but that can be overriden at configure time through 315968651Skris the usual use of --prefix and/or --openssldir, and at run 316068651Skris time with the environment variable OPENSSL_ENGINES. 316168651Skris [Geoff Thorpe and Richard Levitte] 316268651Skris 316368651Skris *) Add Makefile.shared, a helper makefile to build shared 316468651Skris libraries.

Move everything to 429759191Skris the directory crypto/aes, thereby obsoleting crypto/rijndael. 429859191Skris [Stephen Sprunk <stephen@sprunk.org> and Richard Levitte] 429959191Skris 430059191Skris *) SECURITY: remove unsafe setjmp/signal interaction from ui_openssl.c. 430159191Skris [Ben Laurie and Theo de Raadt] 430259191Skris 430359191Skris *) Add option to output public keys in req command. 430459191Skris [Massimiliano Pala madwolf@openca.org] 430559191Skris 430659191Skris *) Use wNAFs in EC_POINTs_mul() for improved efficiency 430759191Skris (up to about 10% better than before for P-192 and P-224). 430859191Skris [Bodo Moeller] 430959191Skris 431059191Skris *) New functions/macros 431159191Skris 431259191Skris SSL_CTX_set_msg_callback(ctx, cb) 431359191Skris SSL_CTX_set_msg_callback_arg(ctx, arg) 431459191Skris SSL_set_msg_callback(ssl, cb) 431559191Skris SSL_set_msg_callback_arg(ssl, arg) 431659191Skris 431759191Skris to request calling a callback function 431859191Skris 431959191Skris void cb(int write_p, int version, int content_type, 432059191Skris const void *buf, size_t len, SSL *ssl, void *arg) 432159191Skris 432259191Skris whenever a protocol message has been completely received 432359191Skris (write_p == 0) or sent (write_p == 1). Here 'version' is the 432459191Skris protocol version according to which the SSL library interprets 432559191Skris the current protocol message (SSL2_VERSION, SSL3_VERSION, or 432659191Skris TLS1_VERSION). 'content_type' is 0 in the case of SSL 2.0, or 432759191Skris the content type as defined in the SSL 3.0/TLS 1.0 protocol 432859191Skris specification (change_cipher_spec(20), alert(21), handshake(22)). 432959191Skris 'buf' and 'len' point to the actual message, 'ssl' to the 433059191Skris SSL object, and 'arg' is the application-defined value set by 433159191Skris SSL[_CTX]_set_msg_callback_arg(). 433259191Skris 433359191Skris 'openssl s_client' and 'openssl s_server' have new '-msg' options 433459191Skris to enable a callback that displays all protocol messages. 433559191Skris [Bodo Moeller] 433659191Skris 433759191Skris *) Change the shared library support so shared libraries are built as 433859191Skris soon as the corresponding static library is finished, and thereby get 433959191Skris openssl and the test programs linked against the shared library. 434059191Skris This still only happens when the keyword "shard" has been given to 434159191Skris the configuration scripts. 434259191Skris 434359191Skris NOTE: shared library support is still an experimental thing, and 434459191Skris backward binary compatibility is still not guaranteed. 434559191Skris ["Maciej W. Rozycki" <macro@ds2.pg.gda.pl> and Richard Levitte] 434659191Skris 434759191Skris *) Add support for Subject Information Access extension. 434859191Skris [Peter Sylvester <Peter.Sylvester@EdelWeb.fr>] 434959191Skris 435059191Skris *) Make BUF_MEM_grow() behaviour more consistent: Initialise to zero 435159191Skris additional bytes when new memory had to be allocated, not just 435259191Skris when reusing an existing buffer. 435359191Skris [Bodo Moeller] 435459191Skris 435559191Skris *) New command line and configuration option 'utf8' for the req command. 435659191Skris This allows field values to be specified as UTF8 strings. 435759191Skris [Steve Henson] 435859191Skris 435959191Skris *) Add -multi and -mr options to "openssl speed" - giving multiple parallel 436059191Skris runs for the former and machine-readable output for the latter. 436159191Skris [Ben Laurie] 436259191Skris 436359191Skris *) Add '-noemailDN' option to 'openssl ca'. This prevents inclusion 436459191Skris of the e-mail address in the DN (i.e., it will go into a certificate 436559191Skris extension only). The new configuration file option 'email_in_dn = no' 436659191Skris has the same effect. 436759191Skris [Massimiliano Pala madwolf@openca.org] 436859191Skris 436959191Skris *) Change all functions with names starting with des_ to be starting 437059191Skris with DES_ instead. Add wrappers that are compatible with libdes, 437159191Skris but are named _ossl_old_des_*. Finally, add macros that map the 437259191Skris des_* symbols to the corresponding _ossl_old_des_* if libdes 437359191Skris compatibility is desired. If OpenSSL 0.9.6c compatibility is 437459191Skris desired, the des_* symbols will be mapped to DES_*, with one 437559191Skris exception. 437659191Skris 437759191Skris Since we provide two compatibility mappings, the user needs to 437859191Skris define the macro OPENSSL_DES_LIBDES_COMPATIBILITY if libdes 437959191Skris compatibility is desired. The default (i.e., when that macro 438059191Skris isn't defined) is OpenSSL 0.9.6c compatibility. 438159191Skris 438259191Skris There are also macros that enable and disable the support of old 438359191Skris des functions altogether. Those are OPENSSL_ENABLE_OLD_DES_SUPPORT 438459191Skris and OPENSSL_DISABLE_OLD_DES_SUPPORT. If none or both of those 438559191Skris are defined, the default will apply: to support the old des routines. 438659191Skris 438759191Skris In either case, one must include openssl/des.h to get the correct 438859191Skris definitions. Do not try to just include openssl/des_old.h, that 438959191Skris won't work. 439059191Skris 439159191Skris NOTE: This is a major break of an old API into a new one. Software 439259191Skris authors are encouraged to switch to the DES_ style functions. Some 439359191Skris time in the future, des_old.h and the libdes compatibility functions 439459191Skris will be disable (i.e. OPENSSL_DISABLE_OLD_DES_SUPPORT will be the 439559191Skris default), and then completely removed. 439659191Skris [Richard Levitte] 439759191Skris 439859191Skris *) Test for certificates which contain unsupported critical extensions. 439959191Skris If such a certificate is found during a verify operation it is 440059191Skris rejected by default: this behaviour can be overridden by either 440159191Skris handling the new error X509_V_ERR_UNHANDLED_CRITICAL_EXTENSION or 440259191Skris by setting the verify flag X509_V_FLAG_IGNORE_CRITICAL. A new function 440359191Skris X509_supported_extension() has also been added which returns 1 if a 440459191Skris particular extension is supported. 440559191Skris [Steve Henson] 440659191Skris 440759191Skris *) Modify the behaviour of EVP cipher functions in similar way to digests 440859191Skris to retain compatibility with existing code. 440959191Skris [Steve Henson] 441059191Skris 441159191Skris *) Modify the behaviour of EVP_DigestInit() and EVP_DigestFinal() to retain 441259191Skris compatibility with existing code. In particular the 'ctx' parameter does 441359191Skris not have to be to be initialized before the call to EVP_DigestInit() and 441459191Skris it is tidied up after a call to EVP_DigestFinal(). New function 441559191Skris EVP_DigestFinal_ex() which does not tidy up the ctx. Similarly function 441659191Skris EVP_MD_CTX_copy() changed to not require the destination to be 441759191Skris initialized valid and new function EVP_MD_CTX_copy_ex() added which 441859191Skris requires the destination to be valid. 441959191Skris 442059191Skris Modify all the OpenSSL digest calls to use EVP_DigestInit_ex(), 442159191Skris EVP_DigestFinal_ex() and EVP_MD_CTX_copy_ex(). 442259191Skris [Steve Henson] 442359191Skris 442459191Skris *) Change ssl3_get_message (ssl/s3_both.c) and the functions using it 442559191Skris so that complete 'Handshake' protocol structures are kept in memory 442659191Skris instead of overwriting 'msg_type' and 'length' with 'body' data. 442759191Skris [Bodo Moeller] 442859191Skris 442959191Skris *) Add an implementation of SSL_add_dir_cert_subjects_to_stack for Win32. 443059191Skris [Massimo Santin via Richard Levitte] 443159191Skris 443259191Skris *) Major restructuring to the underlying ENGINE code. This includes 443359191Skris reduction of linker bloat, separation of pure "ENGINE" manipulation 443459191Skris (initialisation, etc) from functionality dealing with implementations 443559191Skris of specific crypto iterfaces. This change also introduces integrated 443659191Skris support for symmetric ciphers and digest implementations - so ENGINEs 443759191Skris can now accelerate these by providing EVP_CIPHER and EVP_MD 443859191Skris implementations of their own. This is detailed in crypto/engine/README 443959191Skris as it couldn't be adequately described here. However, there are a few 444059191Skris API changes worth noting - some RSA, DSA, DH, and RAND functions that 444159191Skris were changed in the original introduction of ENGINE code have now 444259191Skris reverted back - the hooking from this code to ENGINE is now a good 444359191Skris deal more passive and at run-time, operations deal directly with 444459191Skris RSA_METHODs, DSA_METHODs (etc) as they did before, rather than 444559191Skris dereferencing through an ENGINE pointer any more. Also, the ENGINE 444659191Skris functions dealing with BN_MOD_EXP[_CRT] handlers have been removed - 444759191Skris they were not being used by the framework as there is no concept of a 444859191Skris BIGNUM_METHOD and they could not be generalised to the new 444959191Skris 'ENGINE_TABLE' mechanism that underlies the new code. Similarly, 445059191Skris ENGINE_cpy() has been removed as it cannot be consistently defined in 445159191Skris the new code. 445259191Skris [Geoff Thorpe] 445359191Skris 445459191Skris *) Change ASN1_GENERALIZEDTIME_check() to allow fractional seconds. 445559191Skris [Steve Henson] 445659191Skris 445759191Skris *) Change mkdef.pl to sort symbols that get the same entry number, 445859191Skris and make sure the automatically generated functions ERR_load_* 445959191Skris become part of libeay.num as well. 446059191Skris [Richard Levitte] 446159191Skris 446259191Skris *) New function SSL_renegotiate_pending(). This returns true once 446359191Skris renegotiation has been requested (either SSL_renegotiate() call 446459191Skris or HelloRequest/ClientHello receveived from the peer) and becomes 446559191Skris false once a handshake has been completed. 446659191Skris (For servers, SSL_renegotiate() followed by SSL_do_handshake() 446759191Skris sends a HelloRequest, but does not ensure that a handshake takes 446859191Skris place. SSL_renegotiate_pending() is useful for checking if the 446959191Skris client has followed the request.) 447059191Skris [Bodo Moeller] 447159191Skris 447259191Skris *) New SSL option SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION. 447359191Skris By default, clients may request session resumption even during 447459191Skris renegotiation (if session ID contexts permit); with this option, 447559191Skris session resumption is possible only in the first handshake. 447659191Skris 447759191Skris SSL_OP_ALL is now 0x00000FFFL instead of 0x000FFFFFL. This makes 447859191Skris more bits available for options that should not be part of 447959191Skris SSL_OP_ALL (such as SSL_OP_NO_SESSION_RESUMPTION_ON_RENEGOTIATION). 448059191Skris [Bodo Moeller] 448159191Skris 448259191Skris *) Add some demos for certificate and certificate request creation. 448359191Skris [Steve Henson] 448459191Skris 448559191Skris *) Make maximum certificate chain size accepted from the peer application 448659191Skris settable (SSL*_get/set_max_cert_list()), as proposed by 448759191Skris "Douglas E. Engert" <deengert@anl.gov>. 448859191Skris [Lutz Jaenicke] 448959191Skris 449059191Skris *) Add support for shared libraries for Unixware-7 449159191Skris (Boyd Lynn Gerber <gerberb@zenez.com>). 449259191Skris [Lutz Jaenicke] 449359191Skris 449459191Skris *) Add a "destroy" handler to ENGINEs that allows structural cleanup to 449559191Skris be done prior to destruction. Use this to unload error strings from 449659191Skris ENGINEs that load their own error strings. NB: This adds two new API 449759191Skris functions to "get" and "set" this destroy handler in an ENGINE. 449859191Skris [Geoff Thorpe] 449959191Skris 450059191Skris *) Alter all existing ENGINE implementations (except "openssl" and 450159191Skris "openbsd") to dynamically instantiate their own error strings. This 450259191Skris makes them more flexible to be built both as statically-linked ENGINEs 450359191Skris and self-contained shared-libraries loadable via the "dynamic" ENGINE. 450459191Skris Also, add stub code to each that makes building them as self-contained 450559191Skris shared-libraries easier (see README.ENGINE). 450659191Skris [Geoff Thorpe] 450759191Skris 450859191Skris *) Add a "dynamic" ENGINE that provides a mechanism for binding ENGINE 450959191Skris implementations into applications that are completely implemented in 451059191Skris self-contained shared-libraries. The "dynamic" ENGINE exposes control 451159191Skris commands that can be used to configure what shared-library to load and 451259191Skris to control aspects of the way it is handled. Also, made an update to 451359191Skris the README.ENGINE file that brings its information up-to-date and 451459191Skris provides some information and instructions on the "dynamic" ENGINE 451559191Skris (ie. how to use it, how to build "dynamic"-loadable ENGINEs, etc). 451659191Skris [Geoff Thorpe] 451759191Skris 451859191Skris *) Make it possible to unload ranges of ERR strings with a new 451959191Skris "ERR_unload_strings" function. 452059191Skris [Geoff Thorpe] 452159191Skris 452259191Skris *) Add a copy() function to EVP_MD. 452359191Skris [Ben Laurie] 452459191Skris 452559191Skris *) Make EVP_MD routines take a context pointer instead of just the 452659191Skris md_data void pointer. 452759191Skris [Ben Laurie] 452859191Skris 452959191Skris *) Add flags to EVP_MD and EVP_MD_CTX. EVP_MD_FLAG_ONESHOT indicates 453059191Skris that the digest can only process a single chunk of data 453159191Skris (typically because it is provided by a piece of 453259191Skris hardware). EVP_MD_CTX_FLAG_ONESHOT indicates that the application 453359191Skris is only going to provide a single chunk of data, and hence the 453459191Skris framework needn't accumulate the data for oneshot drivers. 453559191Skris [Ben Laurie] 453659191Skris 453759191Skris *) As with "ERR", make it possible to replace the underlying "ex_data" 453859191Skris functions. This change also alters the storage and management of global 453959191Skris ex_data state - it's now all inside ex_data.c and all "class" code (eg. 454059191Skris RSA, BIO, SSL_CTX, etc) no longer stores its own STACKS and per-class 454159191Skris index counters. The API functions that use this state have been changed 454259191Skris to take a "class_index" rather than pointers to the class's local STACK 454359191Skris and counter, and there is now an API function to dynamically create new 454459191Skris classes. This centralisation allows us to (a) plug a lot of the 454559191Skris thread-safety problems that existed, and (b) makes it possible to clean 454659191Skris up all allocated state using "CRYPTO_cleanup_all_ex_data()". W.r.t. (b) 454759191Skris such data would previously have always leaked in application code and 454859191Skris workarounds were in place to make the memory debugging turn a blind eye 454959191Skris to it. Application code that doesn't use this new function will still 455059191Skris leak as before, but their memory debugging output will announce it now 455159191Skris rather than letting it slide. 455259191Skris 455359191Skris Besides the addition of CRYPTO_cleanup_all_ex_data(), another API change 455459191Skris induced by the "ex_data" overhaul is that X509_STORE_CTX_init() now 455559191Skris has a return value to indicate success or failure. 455659191Skris [Geoff Thorpe] 455759191Skris 455859191Skris *) Make it possible to replace the underlying "ERR" functions such that the 455959191Skris global state (2 LHASH tables and 2 locks) is only used by the "default" 456059191Skris implementation. This change also adds two functions to "get" and "set" 456159191Skris the implementation prior to it being automatically set the first time 456259191Skris any other ERR function takes place. Ie. an application can call "get", 456359191Skris pass the return value to a module it has just loaded, and that module 456459191Skris can call its own "set" function using that value. This means the 456559191Skris module's "ERR" operations will use (and modify) the error state in the 456659191Skris application and not in its own statically linked copy of OpenSSL code. 456759191Skris [Geoff Thorpe] 456859191Skris 456959191Skris *) Give DH, DSA, and RSA types their own "**_up_ref()" function to increment 457059191Skris reference counts. This performs normal REF_PRINT/REF_CHECK macros on 457159191Skris the operation, and provides a more encapsulated way for external code 457259191Skris (crypto/evp/ and ssl/) to do this. Also changed the evp and ssl code 457359191Skris to use these functions rather than manually incrementing the counts. 457459191Skris 457559191Skris Also rename "DSO_up()" function to more descriptive "DSO_up_ref()". 457659191Skris [Geoff Thorpe] 457759191Skris 457859191Skris *) Add EVP test program. 457959191Skris [Ben Laurie] 458059191Skris 458159191Skris *) Add symmetric cipher support to ENGINE. Expect the API to change! 458259191Skris [Ben Laurie] 458359191Skris 458459191Skris *) New CRL functions: X509_CRL_set_version(), X509_CRL_set_issuer_name() 458559191Skris X509_CRL_set_lastUpdate(), X509_CRL_set_nextUpdate(), X509_CRL_sort(), 458659191Skris X509_REVOKED_set_serialNumber(), and X509_REVOKED_set_revocationDate(). 458759191Skris These allow a CRL to be built without having to access X509_CRL fields 458859191Skris directly. Modify 'ca' application to use new functions. 458959191Skris [Steve Henson] 459059191Skris 459159191Skris *) Move SSL_OP_TLS_ROLLBACK_BUG out of the SSL_OP_ALL list of recommended 459259191Skris bug workarounds. Rollback attack detection is a security feature. 459359191Skris The problem will only arise on OpenSSL servers when TLSv1 is not 459459191Skris available (sslv3_server_method() or SSL_OP_NO_TLSv1). 459559191Skris Software authors not wanting to support TLSv1 will have special reasons 459659191Skris for their choice and can explicitly enable this option. 459759191Skris [Bodo Moeller, Lutz Jaenicke] 459859191Skris 459959191Skris *) Rationalise EVP so it can be extended: don't include a union of 460059191Skris cipher/digest structures, add init/cleanup functions for EVP_MD_CTX 460159191Skris (similar to those existing for EVP_CIPHER_CTX). 460259191Skris Usage example: 460359191Skris 460459191Skris EVP_MD_CTX md; 460559191Skris 460659191Skris EVP_MD_CTX_init(&md); /* new function call */ 460759191Skris EVP_DigestInit(&md, EVP_sha1()); 460859191Skris EVP_DigestUpdate(&md, in, len); 460959191Skris EVP_DigestFinal(&md, out, NULL); 461059191Skris EVP_MD_CTX_cleanup(&md); /* new function call */ 461159191Skris 461259191Skris [Ben Laurie] 461359191Skris 461459191Skris *) Make DES key schedule conform to the usual scheme, as well as 461559191Skris correcting its structure. This means that calls to DES functions 461659191Skris now have to pass a pointer to a des_key_schedule instead of a 461759191Skris plain des_key_schedule (which was actually always a pointer 461859191Skris anyway): E.g., 461959191Skris 462059191Skris des_key_schedule ks; 462159191Skris 462259191Skris des_set_key_checked(..., &ks); 462359191Skris des_ncbc_encrypt(..., &ks, ...); 462459191Skris 462555714Skris (Note that a later change renames 'des_...' into 'DES_...'.) 462655714Skris [Ben Laurie] 462755714Skris 462855714Skris *) Initial reduction of linker bloat: the use of some functions, such as 462955714Skris PEM causes large amounts of unused functions to be linked in due to 463055714Skris poor organisation. For example pem_all.c contains every PEM function 463155714Skris which has a knock on effect of linking in large amounts of (unused) 463255714Skris ASN1 code. Grouping together similar functions and splitting unrelated 463355714Skris functions prevents this. 463455714Skris [Steve Henson] 463555714Skris 463655714Skris *) Cleanup of EVP macros. 463755714Skris [Ben Laurie] 463855714Skris 463955714Skris *) Change historical references to {NID,SN,LN}_des_ede and ede3 to add the 464055714Skris correct _ecb suffix. 464155714Skris [Ben Laurie] 464255714Skris 464355714Skris *) Add initial OCSP responder support to ocsp application. The 464455714Skris revocation information is handled using the text based index 464555714Skris use by the ca application. The responder can either handle 464655714Skris requests generated internally, supplied in files (for example 464755714Skris via a CGI script) or using an internal minimal server. 464855714Skris [Steve Henson] 464955714Skris 465055714Skris *) Add configuration choices to get zlib compression for TLS. 465155714Skris [Richard Levitte] 465255714Skris 465355714Skris *) Changes to Kerberos SSL for RFC 2712 compliance: 465455714Skris 1. Implemented real KerberosWrapper, instead of just using 465555714Skris KRB5 AP_REQ message. [Thanks to Simon Wilkinson <sxw@sxw.org.uk>] 465655714Skris 2. Implemented optional authenticator field of KerberosWrapper. 465755714Skris 465855714Skris Added openssl-style ASN.1 macros for Kerberos ticket, ap_req, 465955714Skris and authenticator structs; see crypto/krb5/. 466055714Skris 466155714Skris Generalized Kerberos calls to support multiple Kerberos libraries. 466255714Skris [Vern Staats <staatsvr@asc.hpc.mil>, 466355714Skris Jeffrey Altman <jaltman@columbia.edu> 466455714Skris via Richard Levitte] 466555714Skris 466655714Skris *) Cause 'openssl speed' to use fully hard-coded DSA keys as it 466755714Skris already does with RSA. testdsa.h now has 'priv_key/pub_key' 466855714Skris values for each of the key sizes rather than having just 466955714Skris parameters (and 'speed' generating keys each time). 467055714Skris [Geoff Thorpe] 467155714Skris 467259191Skris *) Speed up EVP routines. 467359191Skris Before: 467459191Skrisencrypt 467555714Skristype 8 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes 467655714Skrisdes-cbc 4408.85k 5560.51k 5778.46k 5862.20k 5825.16k 467755714Skrisdes-cbc 4389.55k 5571.17k 5792.23k 5846.91k 5832.11k 467855714Skrisdes-cbc 4394.32k 5575.92k 5807.44k 5848.37k 5841.30k 467955714Skrisdecrypt 468055714Skrisdes-cbc 3482.66k 5069.49k 5496.39k 5614.16k 5639.28k 468155714Skrisdes-cbc 3480.74k 5068.76k 5510.34k 5609.87k 5635.52k 468255714Skrisdes-cbc 3483.72k 5067.62k 5504.60k 5708.01k 5724.80k 468355714Skris After: 468455714Skrisencrypt 468555714Skrisdes-cbc 4660.16k 5650.19k 5807.19k 5827.13k 5783.32k 468655714Skrisdecrypt 468755714Skrisdes-cbc 3624.96k 5258.21k 5530.91k 5624.30k 5628.26k 468859191Skris [Ben Laurie] 468955714Skris 469055714Skris *) Added the OS2-EMX target. 469155714Skris ["Brian Havard" <brianh@kheldar.apana.org.au> and Richard Levitte] 469255714Skris 469355714Skris *) Rewrite apps to use NCONF routines instead of the old CONF. New functions 469455714Skris to support NCONF routines in extension code. New function CONF_set_nconf() 469555714Skris to allow functions which take an NCONF to also handle the old LHASH 469655714Skris structure: this means that the old CONF compatible routines can be 469755714Skris retained (in particular wrt extensions) without having to duplicate the 469855714Skris code. New function X509V3_add_ext_nconf_sk to add extensions to a stack. 469955714Skris [Steve Henson] 470055714Skris 470155714Skris *) Enhance the general user interface with mechanisms for inner control 470255714Skris and with possibilities to have yes/no kind of prompts. 470355714Skris [Richard Levitte] 470455714Skris 470555714Skris *) Change all calls to low level digest routines in the library and 470655714Skris applications to use EVP. Add missing calls to HMAC_cleanup() and 470755714Skris don't assume HMAC_CTX can be copied using memcpy(). 470855714Skris [Verdon Walker <VWalker@novell.com>, Steve Henson] 470955714Skris 471055714Skris *) Add the possibility to control engines through control names but with 471155714Skris arbitrary arguments instead of just a string. 471255714Skris Change the key loaders to take a UI_METHOD instead of a callback 471355714Skris function pointer. NOTE: this breaks binary compatibility with earlier 471455714Skris versions of OpenSSL [engine]. 471555714Skris Adapt the nCipher code for these new conditions and add a card insertion 471655714Skris callback. 471755714Skris [Richard Levitte] 471855714Skris 471955714Skris *) Enhance the general user interface with mechanisms to better support 472055714Skris dialog box interfaces, application-defined prompts, the possibility 472155714Skris to use defaults (for example default passwords from somewhere else) 472255714Skris and interrupts/cancellations. 472355714Skris [Richard Levitte] 472455714Skris 472555714Skris *) Tidy up PKCS#12 attribute handling. Add support for the CSP name 472655714Skris attribute in PKCS#12 files, add new -CSP option to pkcs12 utility. 472755714Skris [Steve Henson] 472855714Skris 472955714Skris *) Fix a memory leak in 'sk_dup()' in the case reallocation fails. (Also 473055714Skris tidy up some unnecessarily weird code in 'sk_new()'). 473155714Skris [Geoff, reported by Diego Tartara <dtartara@novamens.com>] 473255714Skris 473355714Skris *) Change the key loading routines for ENGINEs to use the same kind 473455714Skris callback (pem_password_cb) as all other routines that need this 473555714Skris kind of callback. 473655714Skris [Richard Levitte] 473755714Skris 473855714Skris *) Increase ENTROPY_NEEDED to 32 bytes, as Rijndael can operate with 473955714Skris 256 bit (=32 byte) keys. Of course seeding with more entropy bytes 474055714Skris than this minimum value is recommended. 474155714Skris [Lutz Jaenicke] 474255714Skris 474355714Skris *) New random seeder for OpenVMS, using the system process statistics 474455714Skris that are easily reachable. 474555714Skris [Richard Levitte] 474655714Skris 474755714Skris *) Windows apparently can't transparently handle global 474855714Skris variables defined in DLLs. Initialisations such as: 474955714Skris 475055714Skris const ASN1_ITEM *it = &ASN1_INTEGER_it; 475155714Skris 475255714Skris wont compile. This is used by the any applications that need to 475355714Skris declare their own ASN1 modules. This was fixed by adding the option 475455714Skris EXPORT_VAR_AS_FN to all Win32 platforms, although this isn't strictly 475555714Skris needed for static libraries under Win32. 475655714Skris [Steve Henson] 475755714Skris 475855714Skris *) New functions X509_PURPOSE_set() and X509_TRUST_set() to handle 475955714Skris setting of purpose and trust fields. New X509_STORE trust and 476055714Skris purpose functions and tidy up setting in other SSL functions. 476155714Skris [Steve Henson] 476255714Skris 476355714Skris *) Add copies of X509_STORE_CTX fields and callbacks to X509_STORE 476455714Skris structure. These are inherited by X509_STORE_CTX when it is 476555714Skris initialised. This allows various defaults to be set in the 476655714Skris X509_STORE structure (such as flags for CRL checking and custom 476755714Skris purpose or trust settings) for functions which only use X509_STORE_CTX 476855714Skris internally such as S/MIME. 476955714Skris 477055714Skris Modify X509_STORE_CTX_purpose_inherit() so it only sets purposes and 477155714Skris trust settings if they are not set in X509_STORE. This allows X509_STORE 477255714Skris purposes and trust (in S/MIME for example) to override any set by default. 477355714Skris 477455714Skris Add command line options for CRL checking to smime, s_client and s_server 477555714Skris applications. 477655714Skris [Steve Henson] 477755714Skris 477855714Skris *) Initial CRL based revocation checking. If the CRL checking flag(s) 477955714Skris are set then the CRL is looked up in the X509_STORE structure and 478055714Skris its validity and signature checked, then if the certificate is found 478155714Skris in the CRL the verify fails with a revoked error. 478255714Skris 478355714Skris Various new CRL related callbacks added to X509_STORE_CTX structure. 478455714Skris 478555714Skris Command line options added to 'verify' application to support this. 478655714Skris 478755714Skris This needs some additional work, such as being able to handle multiple 478855714Skris CRLs with different times, extension based lookup (rather than just 478955714Skris by subject name) and ultimately more complete V2 CRL extension 479055714Skris handling. 479155714Skris [Steve Henson] 479255714Skris 479355714Skris *) Add a general user interface API (crypto/ui/). This is designed 479455714Skris to replace things like des_read_password and friends (backward 479555714Skris compatibility functions using this new API are provided). 479655714Skris The purpose is to remove prompting functions from the DES code 479755714Skris section as well as provide for prompting through dialog boxes in 479879998Skris a window system and the like. 479955714Skris [Richard Levitte] 480055714Skris 480155714Skris *) Add "ex_data" support to ENGINE so implementations can add state at a 480255714Skris per-structure level rather than having to store it globally. 480355714Skris [Geoff] 480455714Skris 480555714Skris *) Make it possible for ENGINE structures to be copied when retrieved by 480655714Skris ENGINE_by_id() if the ENGINE specifies a new flag: ENGINE_FLAGS_BY_ID_COPY. 480755714Skris This causes the "original" ENGINE structure to act like a template, 480855714Skris analogous to the RSA vs. RSA_METHOD type of separation. Because of this 480955714Skris operational state can be localised to each ENGINE structure, despite the 481055714Skris fact they all share the same "methods". New ENGINE structures returned in 481155714Skris this case have no functional references and the return value is the single 481255714Skris structural reference. This matches the single structural reference returned 481355714Skris by ENGINE_by_id() normally, when it is incremented on the pre-existing 481455714Skris ENGINE structure. 481555714Skris [Geoff] 481655714Skris 481755714Skris *) Fix ASN1 decoder when decoding type ANY and V_ASN1_OTHER: since this 481855714Skris needs to match any other type at all we need to manually clear the 481955714Skris tag cache. 482055714Skris [Steve Henson] 482155714Skris 482255714Skris *) Changes to the "openssl engine" utility to include; 482355714Skris - verbosity levels ('-v', '-vv', and '-vvv') that provide information 482455714Skris about an ENGINE's available control commands. 482555714Skris - executing control commands from command line arguments using the 482655714Skris '-pre' and '-post' switches. '-post' is only used if '-t' is 482755714Skris specified and the ENGINE is successfully initialised. The syntax for 482855714Skris the individual commands are colon-separated, for example; 482955714Skris openssl engine chil -pre FORK_CHECK:0 -pre SO_PATH:/lib/test.so 483055714Skris [Geoff] 483155714Skris 483255714Skris *) New dynamic control command support for ENGINEs. ENGINEs can now 483355714Skris declare their own commands (numbers), names (strings), descriptions, 483455714Skris and input types for run-time discovery by calling applications. A 483555714Skris subset of these commands are implicitly classed as "executable" 483655714Skris depending on their input type, and only these can be invoked through 483755714Skris the new string-based API function ENGINE_ctrl_cmd_string(). (Eg. this 483855714Skris can be based on user input, config files, etc). The distinction is 483955714Skris that "executable" commands cannot return anything other than a boolean 484055714Skris result and can only support numeric or string input, whereas some 484155714Skris discoverable commands may only be for direct use through 484255714Skris ENGINE_ctrl(), eg. supporting the exchange of binary data, function 484355714Skris pointers, or other custom uses. The "executable" commands are to 484455714Skris support parameterisations of ENGINE behaviour that can be 484555714Skris unambiguously defined by ENGINEs and used consistently across any 484655714Skris OpenSSL-based application. Commands have been added to all the 484755714Skris existing hardware-supporting ENGINEs, noticeably "SO_PATH" to allow 484855714Skris control over shared-library paths without source code alterations. 484955714Skris [Geoff] 485055714Skris 485155714Skris *) Changed all ENGINE implementations to dynamically allocate their 485255714Skris ENGINEs rather than declaring them statically. Apart from this being 485355714Skris necessary with the removal of the ENGINE_FLAGS_MALLOCED distinction, 485455714Skris this also allows the implementations to compile without using the 485555714Skris internal engine_int.h header. 485655714Skris [Geoff] 485755714Skris 485855714Skris *) Minor adjustment to "rand" code. RAND_get_rand_method() now returns a 485955714Skris 'const' value. Any code that should be able to modify a RAND_METHOD 486055714Skris should already have non-const pointers to it (ie. they should only 486155714Skris modify their own ones). 486255714Skris [Geoff] 486355714Skris 486455714Skris *) Made a variety of little tweaks to the ENGINE code. 486555714Skris - "atalla" and "ubsec" string definitions were moved from header files 486655714Skris to C code. "nuron" string definitions were placed in variables 486755714Skris rather than hard-coded - allowing parameterisation of these values 486855714Skris later on via ctrl() commands. 486955714Skris - Removed unused "#if 0"'d code. 487055714Skris - Fixed engine list iteration code so it uses ENGINE_free() to release 487155714Skris structural references. 487255714Skris - Constified the RAND_METHOD element of ENGINE structures. 487355714Skris - Constified various get/set functions as appropriate and added 487455714Skris missing functions (including a catch-all ENGINE_cpy that duplicates 487555714Skris all ENGINE values onto a new ENGINE except reference counts/state). 487655714Skris - Removed NULL parameter checks in get/set functions. Setting a method 487755714Skris or function to NULL is a way of cancelling out a previously set 487855714Skris value. Passing a NULL ENGINE parameter is just plain stupid anyway 487955714Skris and doesn't justify the extra error symbols and code. 488055714Skris - Deprecate the ENGINE_FLAGS_MALLOCED define and move the area for 488155714Skris flags from engine_int.h to engine.h. 488255714Skris - Changed prototypes for ENGINE handler functions (init(), finish(), 488355714Skris ctrl(), key-load functions, etc) to take an (ENGINE*) parameter. 488455714Skris [Geoff] 488555714Skris 488655714Skris *) Implement binary inversion algorithm for BN_mod_inverse in addition 488755714Skris to the algorithm using long division. The binary algorithm can be 488855714Skris used only if the modulus is odd. On 32-bit systems, it is faster 488955714Skris only for relatively small moduli (roughly 20-30% for 128-bit moduli, 489055714Skris roughly 5-15% for 256-bit moduli), so we use it only for moduli 489155714Skris up to 450 bits. In 64-bit environments, the binary algorithm 489255714Skris appears to be advantageous for much longer moduli; here we use it 489355714Skris for moduli up to 2048 bits. 489455714Skris [Bodo Moeller] 489555714Skris 489655714Skris *) Rewrite CHOICE field setting in ASN1_item_ex_d2i(). The old code 489755714Skris could not support the combine flag in choice fields. 489855714Skris [Steve Henson] 489955714Skris 490055714Skris *) Add a 'copy_extensions' option to the 'ca' utility. This copies 490155714Skris extensions from a certificate request to the certificate. 490255714Skris [Steve Henson] 490355714Skris 490455714Skris *) Allow multiple 'certopt' and 'nameopt' options to be separated 490555714Skris by commas. Add 'namopt' and 'certopt' options to the 'ca' config 490655714Skris file: this allows the display of the certificate about to be 490755714Skris signed to be customised, to allow certain fields to be included 490855714Skris or excluded and extension details. The old system didn't display 490955714Skris multicharacter strings properly, omitted fields not in the policy 491055714Skris and couldn't display additional details such as extensions. 491155714Skris [Steve Henson] 491255714Skris 491355714Skris *) Function EC_POINTs_mul for multiple scalar multiplication 491455714Skris of an arbitrary number of elliptic curve points 491555714Skris \sum scalars[i]*points[i], 491655714Skris optionally including the generator defined for the EC_GROUP: 491755714Skris scalar*generator + \sum scalars[i]*points[i]. 491855714Skris 491955714Skris EC_POINT_mul is a simple wrapper function for the typical case 492055714Skris that the point list has just one item (besides the optional 492155714Skris generator). 492255714Skris [Bodo Moeller] 492355714Skris 492455714Skris *) First EC_METHODs for curves over GF(p): 492555714Skris 492655714Skris EC_GFp_simple_method() uses the basic BN_mod_mul and BN_mod_sqr 492755714Skris operations and provides various method functions that can also 492855714Skris operate with faster implementations of modular arithmetic. 492955714Skris 493055714Skris EC_GFp_mont_method() reuses most functions that are part of 493155714Skris EC_GFp_simple_method, but uses Montgomery arithmetic. 493255714Skris 493355714Skris [Bodo Moeller; point addition and point doubling 493455714Skris implementation directly derived from source code provided by 493555714Skris Lenka Fibikova <fibikova@exp-math.uni-essen.de>] 493655714Skris 493755714Skris *) Framework for elliptic curves (crypto/ec/ec.h, crypto/ec/ec_lcl.h, 493855714Skris crypto/ec/ec_lib.c): 493955714Skris 494055714Skris Curves are EC_GROUP objects (with an optional group generator) 494155714Skris based on EC_METHODs that are built into the library. 494255714Skris 494355714Skris Points are EC_POINT objects based on EC_GROUP objects. 494455714Skris 494555714Skris Most of the framework would be able to handle curves over arbitrary 494655714Skris finite fields, but as there are no obvious types for fields other 494755714Skris than GF(p), some functions are limited to that for now. 494855714Skris [Bodo Moeller] 494955714Skris 495055714Skris *) Add the -HTTP option to s_server. It is similar to -WWW, but requires 495155714Skris that the file contains a complete HTTP response. 495255714Skris [Richard Levitte] 495355714Skris 495455714Skris *) Add the ec directory to mkdef.pl and mkfiles.pl. In mkdef.pl 495555714Skris change the def and num file printf format specifier from "%-40sXXX" 495655714Skris to "%-39s XXX". The latter will always guarantee a space after the 495755714Skris field while the former will cause them to run together if the field 495855714Skris is 40 of more characters long. 495955714Skris [Steve Henson] 496055714Skris 496155714Skris *) Constify the cipher and digest 'method' functions and structures 496255714Skris and modify related functions to take constant EVP_MD and EVP_CIPHER 496355714Skris pointers. 496455714Skris [Steve Henson] 496555714Skris 496655714Skris *) Hide BN_CTX structure details in bn_lcl.h instead of publishing them 496755714Skris in <openssl/bn.h>. Also further increase BN_CTX_NUM to 32. 496855714Skris [Bodo Moeller] 496955714Skris 497055714Skris *) Modify EVP_Digest*() routines so they now return values. Although the 497155714Skris internal software routines can never fail additional hardware versions 497255714Skris might. 497355714Skris [Steve Henson] 497455714Skris 497555714Skris *) Clean up crypto/err/err.h and change some error codes to avoid conflicts: 497655714Skris 497755714Skris Previously ERR_R_FATAL was too small and coincided with ERR_LIB_PKCS7 497855714Skris (= ERR_R_PKCS7_LIB); it is now 64 instead of 32. 497955714Skris 498055714Skris ASN1 error codes 498155714Skris ERR_R_NESTED_ASN1_ERROR 498255714Skris ... 498355714Skris ERR_R_MISSING_ASN1_EOS 498455714Skris were 4 .. 9, conflicting with 498555714Skris ERR_LIB_RSA (= ERR_R_RSA_LIB) 498655714Skris ... 498755714Skris ERR_LIB_PEM (= ERR_R_PEM_LIB). 498855714Skris They are now 58 .. 63 (i.e., just below ERR_R_FATAL). 498955714Skris 499055714Skris Add new error code 'ERR_R_INTERNAL_ERROR'. 499155714Skris [Bodo Moeller] 499255714Skris 499355714Skris *) Don't overuse locks in crypto/err/err.c: For data retrieval, CRYPTO_r_lock 499455714Skris suffices. 499555714Skris [Bodo Moeller] 499655714Skris 499755714Skris *) New option '-subj arg' for 'openssl req' and 'openssl ca'.

Formats that can be parsed are 500055714Skris 'CN=Some Name, OU=myOU, C=IT' 500155714Skris and 500255714Skris 'CN=Some Name/OU=myOU/C=IT'. 500355714Skris 500455714Skris Add options '-batch' and '-verbose' to 'openssl req'. 500555714Skris [Massimiliano Pala <madwolf@hackmasters.net>] 500655714Skris 500755714Skris *) Introduce the possibility to access global variables through 500855714Skris functions on platform were that's the best way to handle exporting 500955714Skris global variables in shared libraries. To enable this functionality, 501055714Skris one must configure with "EXPORT_VAR_AS_FN" or defined the C macro 501155714Skris "OPENSSL_EXPORT_VAR_AS_FUNCTION" in crypto/opensslconf.h (the latter 501255714Skris is normally done by Configure or something similar). 501355714Skris 501455714Skris To implement a global variable, use the macro OPENSSL_IMPLEMENT_GLOBAL 501555714Skris in the source file (foo.c) like this: 501655714Skris 501755714Skris OPENSSL_IMPLEMENT_GLOBAL(int,foo)=1; 501855714Skris OPENSSL_IMPLEMENT_GLOBAL(double,bar); 501955714Skris 502055714Skris To declare a global variable, use the macros OPENSSL_DECLARE_GLOBAL 502155714Skris and OPENSSL_GLOBAL_REF in the header file (foo.h) like this: 502255714Skris 502355714Skris OPENSSL_DECLARE_GLOBAL(int,foo); 502455714Skris #define foo OPENSSL_GLOBAL_REF(foo) 502555714Skris OPENSSL_DECLARE_GLOBAL(double,bar); 502655714Skris #define bar OPENSSL_GLOBAL_REF(bar) 502755714Skris 502855714Skris The #defines are very important, and therefore so is including the 502955714Skris header file everywhere where the defined globals are used. 503055714Skris 503155714Skris The macro OPENSSL_EXPORT_VAR_AS_FUNCTION also affects the definition 503255714Skris of ASN.1 items, but that structure is a bit different. 503355714Skris 503455714Skris The largest change is in util/mkdef.pl which has been enhanced with 503555714Skris better and easier to understand logic to choose which symbols should 503655714Skris go into the Windows .def files as well as a number of fixes and code 503755714Skris cleanup (among others, algorithm keywords are now sorted 503855714Skris lexicographically to avoid constant rewrites). 503955714Skris [Richard Levitte] 504055714Skris 504155714Skris *) In BN_div() keep a copy of the sign of 'num' before writing the 504255714Skris result to 'rm' because if rm==num the value will be overwritten 504355714Skris and produce the wrong result if 'num' is negative: this caused 504455714Skris problems with BN_mod() and BN_nnmod(). 504555714Skris [Steve Henson] 504655714Skris 504755714Skris *) Function OCSP_request_verify(). This checks the signature on an 504855714Skris OCSP request and verifies the signer certificate. The signer 504955714Skris certificate is just checked for a generic purpose and OCSP request 505055714Skris trust settings. 505155714Skris [Steve Henson] 505255714Skris 505355714Skris *) Add OCSP_check_validity() function to check the validity of OCSP 505455714Skris responses. OCSP responses are prepared in real time and may only 505555714Skris be a few seconds old. Simply checking that the current time lies 505655714Skris between thisUpdate and nextUpdate max reject otherwise valid responses 505755714Skris caused by either OCSP responder or client clock inaccuracy. Instead 505855714Skris we allow thisUpdate and nextUpdate to fall within a certain period of 505955714Skris the current time. The age of the response can also optionally be 506055714Skris checked. Two new options -validity_period and -status_age added to 506155714Skris ocsp utility. 506255714Skris [Steve Henson] 506355714Skris 506455714Skris *) If signature or public key algorithm is unrecognized print out its 506555714Skris OID rather that just UNKNOWN. 506655714Skris [Steve Henson] 506755714Skris 506855714Skris *) Change OCSP_cert_to_id() to tolerate a NULL subject certificate and 506955714Skris OCSP_cert_id_new() a NULL serialNumber. This allows a partial certificate 507055714Skris ID to be generated from the issuer certificate alone which can then be 507155714Skris passed to OCSP_id_issuer_cmp(). 507255714Skris [Steve Henson] 507355714Skris 507455714Skris *) New compilation option ASN1_ITEM_FUNCTIONS. This causes the new 507555714Skris ASN1 modules to export functions returning ASN1_ITEM pointers 507655714Skris instead of the ASN1_ITEM structures themselves. This adds several 507755714Skris new macros which allow the underlying ASN1 function/structure to 507855714Skris be accessed transparently. As a result code should not use ASN1_ITEM 507955714Skris references directly (such as &X509_it) but instead use the relevant 508055714Skris macros (such as ASN1_ITEM_rptr(X509)). This option is to allow 508155714Skris use of the new ASN1 code on platforms where exporting structures 508255714Skris is problematical (for example in shared libraries) but exporting 508355714Skris functions returning pointers to structures is not. 508455714Skris [Steve Henson] 508555714Skris 508655714Skris *) Add support for overriding the generation of SSL/TLS session IDs. 508755714Skris These callbacks can be registered either in an SSL_CTX or per SSL. 508855714Skris The purpose of this is to allow applications to control, if they wish, 508955714Skris the arbitrary values chosen for use as session IDs, particularly as it 509055714Skris can be useful for session caching in multiple-server environments. A 509155714Skris command-line switch for testing this (and any client code that wishes 509255714Skris to use such a feature) has been added to "s_server". 509355714Skris [Geoff Thorpe, Lutz Jaenicke] 509455714Skris 509555714Skris *) Modify mkdef.pl to recognise and parse preprocessor conditionals 509655714Skris of the form '#if defined(...) || defined(...) || ...' and 509755714Skris '#if !defined(...) && !defined(...) && ...'. This also avoids 509855714Skris the growing number of special cases it was previously handling. 509955714Skris [Richard Levitte] 510055714Skris 510155714Skris *) Make all configuration macros available for application by making 510255714Skris sure they are available in opensslconf.h, by giving them names starting 510355714Skris with "OPENSSL_" to avoid conflicts with other packages and by making 510455714Skris sure e_os2.h will cover all platform-specific cases together with 510555714Skris opensslconf.h. 510655714Skris Additionally, it is now possible to define configuration/platform- 510755714Skris specific names (called "system identities"). In the C code, these 510855714Skris are prefixed with "OPENSSL_SYSNAME_". e_os2.h will create another 510955714Skris macro with the name beginning with "OPENSSL_SYS_", which is determined 511055714Skris from "OPENSSL_SYSNAME_*" or compiler-specific macros depending on 511155714Skris what is available. 511255714Skris [Richard Levitte] 511355714Skris 511455714Skris *) New option -set_serial to 'req' and 'x509' this allows the serial 511555714Skris number to use to be specified on the command line. Previously self 511655714Skris signed certificates were hard coded with serial number 0 and the 511755714Skris CA options of 'x509' had to use a serial number in a file which was 511855714Skris auto incremented. 511955714Skris [Steve Henson] 512055714Skris 512155714Skris *) New options to 'ca' utility to support V2 CRL entry extensions. 512255714Skris Currently CRL reason, invalidity date and hold instruction are 512355714Skris supported. Add new CRL extensions to V3 code and some new objects. 512455714Skris [Steve Henson] 512555714Skris 512655714Skris *) New function EVP_CIPHER_CTX_set_padding() this is used to 512755714Skris disable standard block padding (aka PKCS#5 padding) in the EVP 512855714Skris API, which was previously mandatory. This means that the data is 512955714Skris not padded in any way and so the total length much be a multiple 513055714Skris of the block size, otherwise an error occurs. 513155714Skris [Steve Henson] 513255714Skris 513355714Skris *) Initial (incomplete) OCSP SSL support. 513455714Skris [Steve Henson] 513555714Skris 513655714Skris *) New function OCSP_parse_url(). This splits up a URL into its host, 513755714Skris port and path components: primarily to parse OCSP URLs. New -url 513855714Skris option to ocsp utility. 513955714Skris [Steve Henson] 514055714Skris 514155714Skris *) New nonce behavior. The return value of OCSP_check_nonce() now 514255714Skris reflects the various checks performed. Applications can decide 514355714Skris whether to tolerate certain situations such as an absent nonce 514455714Skris in a response when one was present in a request: the ocsp application 514555714Skris just prints out a warning. New function OCSP_add1_basic_nonce() 514655714Skris this is to allow responders to include a nonce in a response even if 514755714Skris the request is nonce-less. 514855714Skris [Steve Henson] 514955714Skris 515055714Skris *) Disable stdin buffering in load_cert (apps/apps.c) so that no certs are 515155714Skris skipped when using openssl x509 multiple times on a single input file, 515255714Skris e.g. "(openssl x509 -out cert1; openssl x509 -out cert2) <certs". 515355714Skris [Bodo Moeller] 515455714Skris 515555714Skris *) Make ASN1_UTCTIME_set_string() and ASN1_GENERALIZEDTIME_set_string() 515655714Skris set string type: to handle setting ASN1_TIME structures. Fix ca 515755714Skris utility to correctly initialize revocation date of CRLs. 515855714Skris [Steve Henson] 515955714Skris 516055714Skris *) New option SSL_OP_CIPHER_SERVER_PREFERENCE allows the server to override 516155714Skris the clients preferred ciphersuites and rather use its own preferences. 516255714Skris Should help to work around M$ SGC (Server Gated Cryptography) bug in 516355714Skris Internet Explorer by ensuring unchanged hash method during stepup. 516455714Skris (Also replaces the broken/deactivated SSL_OP_NON_EXPORT_FIRST option.) 516555714Skris [Lutz Jaenicke] 516655714Skris 516755714Skris *) Make mkdef.pl recognise all DECLARE_ASN1 macros, change rijndael 516855714Skris to aes and add a new 'exist' option to print out symbols that don't 516955714Skris appear to exist. 517055714Skris [Steve Henson] 517155714Skris 517255714Skris *) Additional options to ocsp utility to allow flags to be set and 517355714Skris additional certificates supplied. 517455714Skris [Steve Henson] 517555714Skris 517655714Skris *) Add the option -VAfile to 'openssl ocsp', so the user can give the 517755714Skris OCSP client a number of certificate to only verify the response 517855714Skris signature against. 517955714Skris [Richard Levitte] 518055714Skris 518155714Skris *) Update Rijndael code to version 3.0 and change EVP AES ciphers to 518255714Skris handle the new API. Currently only ECB, CBC modes supported. Add new 518355714Skris AES OIDs. 518455714Skris 518555714Skris Add TLS AES ciphersuites as described in RFC3268, "Advanced 518655714Skris Encryption Standard (AES) Ciphersuites for Transport Layer 518755714Skris Security (TLS)". (In beta versions of OpenSSL 0.9.7, these were 518855714Skris not enabled by default and were not part of the "ALL" ciphersuite 518955714Skris alias because they were not yet official; they could be 519055714Skris explicitly requested by specifying the "AESdraft" ciphersuite 519155714Skris group alias. In the final release of OpenSSL 0.9.7, the group 519255714Skris alias is called "AES" and is part of "ALL".) 519355714Skris [Ben Laurie, Steve Henson, Bodo Moeller] 519455714Skris 519555714Skris *) New function OCSP_copy_nonce() to copy nonce value (if present) from 519655714Skris request to response. 519755714Skris [Steve Henson] 519855714Skris 519955714Skris *) Functions for OCSP responders. OCSP_request_onereq_count(), 520055714Skris OCSP_request_onereq_get0(), OCSP_onereq_get0_id() and OCSP_id_get0_info() 520155714Skris extract information from a certificate request. OCSP_response_create() 520255714Skris creates a response and optionally adds a basic response structure. 520355714Skris OCSP_basic_add1_status() adds a complete single response to a basic 520455714Skris response and returns the OCSP_SINGLERESP structure just added (to allow 520555714Skris extensions to be included for example). OCSP_basic_add1_cert() adds a 520655714Skris certificate to a basic response and OCSP_basic_sign() signs a basic 520755714Skris response with various flags. New helper functions ASN1_TIME_check() 520855714Skris (checks validity of ASN1_TIME structure) and ASN1_TIME_to_generalizedtime() 520955714Skris (converts ASN1_TIME to GeneralizedTime). 521055714Skris [Steve Henson] 521155714Skris 521255714Skris *) Various new functions. EVP_Digest() combines EVP_Digest{Init,Update,Final}() 521355714Skris in a single operation. X509_get0_pubkey_bitstr() extracts the public_key 521455714Skris structure from a certificate. X509_pubkey_digest() digests the public_key 521555714Skris contents: this is used in various key identifiers. 521655714Skris [Steve Henson] 521755714Skris 521855714Skris *) Make sk_sort() tolerate a NULL argument. 521955714Skris [Steve Henson reported by Massimiliano Pala <madwolf@comune.modena.it>] 522055714Skris 522155714Skris *) New OCSP verify flag OCSP_TRUSTOTHER. When set the "other" certificates 522255714Skris passed by the function are trusted implicitly. If any of them signed the 522355714Skris response then it is assumed to be valid and is not verified. 522455714Skris [Steve Henson] 522555714Skris 522655714Skris *) In PKCS7_set_type() initialise content_type in PKCS7_ENC_CONTENT 522755714Skris to data. This was previously part of the PKCS7 ASN1 code. This 522855714Skris was causing problems with OpenSSL created PKCS#12 and PKCS#7 structures. 522955714Skris [Steve Henson, reported by Kenneth R.

Now it 524055714Skris is initialised to -1 but X509_time_adj() now has to check the value 524155714Skris and use ASN1_TIME_set() if the value is not V_ASN1_UTCTIME or 524255714Skris V_ASN1_GENERALIZEDTIME, without this it always uses GeneralizedTime. 524355714Skris [Steve Henson, reported by Kenneth R. Robinette 524455714Skris <support@securenetterm.com>] 524555714Skris 524655714Skris *) Fixes to BN_to_ASN1_INTEGER when bn is zero. This would previously 524755714Skris result in a zero length in the ASN1_INTEGER structure which was 524855714Skris not consistent with the structure when d2i_ASN1_INTEGER() was used 524955714Skris and would cause ASN1_INTEGER_cmp() to fail. Enhance s2i_ASN1_INTEGER() 525055714Skris to cope with hex and negative integers. Fix bug in i2a_ASN1_INTEGER() 525155714Skris where it did not print out a minus for negative ASN1_INTEGER. 525255714Skris [Steve Henson] 525355714Skris 525455714Skris *) Add summary printout to ocsp utility. The various functions which 525555714Skris convert status values to strings have been renamed to: 525655714Skris OCSP_response_status_str(), OCSP_cert_status_str() and 525755714Skris OCSP_crl_reason_str() and are no longer static. New options 525855714Skris to verify nonce values and to disable verification. OCSP response 525955714Skris printout format cleaned up. 526055714Skris [Steve Henson] 526155714Skris 526255714Skris *) Add additional OCSP certificate checks. These are those specified 526355714Skris in RFC2560. This consists of two separate checks: the CA of the 526455714Skris certificate being checked must either be the OCSP signer certificate 526555714Skris or the issuer of the OCSP signer certificate. In the latter case the 526655714Skris OCSP signer certificate must contain the OCSP signing extended key 526755714Skris usage. This check is performed by attempting to match the OCSP 526855714Skris signer or the OCSP signer CA to the issuerNameHash and issuerKeyHash 526955714Skris in the OCSP_CERTID structures of the response. 527055714Skris [Steve Henson] 527155714Skris 527255714Skris *) Initial OCSP certificate verification added to OCSP_basic_verify() 527355714Skris and related routines. This uses the standard OpenSSL certificate 527455714Skris verify routines to perform initial checks (just CA validity) and 527555714Skris to obtain the certificate chain. Then additional checks will be 527655714Skris performed on the chain. Currently the root CA is checked to see 527755714Skris if it is explicitly trusted for OCSP signing. This is used to set 527855714Skris a root CA as a global signing root: that is any certificate that 527955714Skris chains to that CA is an acceptable OCSP signing certificate. 528055714Skris [Steve Henson] 528155714Skris 528255714Skris *) New '-extfile ...' option to 'openssl ca' for reading X.509v3 528355714Skris extensions from a separate configuration file. 528455714Skris As when reading extensions from the main configuration file, 528555714Skris the '-extensions ...' option may be used for specifying the 528655714Skris section to use. 528755714Skris [Massimiliano Pala <madwolf@comune.modena.it>] 528855714Skris 528955714Skris *) New OCSP utility. Allows OCSP requests to be generated or 529055714Skris read. The request can be sent to a responder and the output 529155714Skris parsed, outputed or printed in text form. Not complete yet: 529255714Skris still needs to check the OCSP response validity. 529355714Skris [Steve Henson] 529455714Skris 529555714Skris *) New subcommands for 'openssl ca': 529655714Skris 'openssl ca -status <serial>' prints the status of the cert with 529755714Skris the given serial number (according to the index file). 529855714Skris 'openssl ca -updatedb' updates the expiry status of certificates 529955714Skris in the index file. 530055714Skris [Massimiliano Pala <madwolf@comune.modena.it>] 530155714Skris 530255714Skris *) New '-newreq-nodes' command option to CA.pl. This is like 530355714Skris '-newreq', but calls 'openssl req' with the '-nodes' option 530455714Skris so that the resulting key is not encrypted. 530555714Skris [Damien Miller <djm@mindrot.org>] 530655714Skris 530755714Skris *) New configuration for the GNU Hurd. 530855714Skris [Jonathan Bartlett <johnnyb@wolfram.com> via Richard Levitte] 530955714Skris 531055714Skris *) Initial code to implement OCSP basic response verify. This 531155714Skris is currently incomplete. Currently just finds the signer's 531255714Skris certificate and verifies the signature on the response. 531355714Skris [Steve Henson] 531455714Skris 531555714Skris *) New SSLeay_version code SSLEAY_DIR to determine the compiled-in 531655714Skris value of OPENSSLDIR. This is available via the new '-d' option 531755714Skris to 'openssl version', and is also included in 'openssl version -a'. 531855714Skris [Bodo Moeller] 531955714Skris 532055714Skris *) Allowing defining memory allocation callbacks that will be given 532155714Skris file name and line number information in additional arguments 532255714Skris (a const char* and an int). The basic functionality remains, as 532355714Skris well as the original possibility to just replace malloc(), 532455714Skris realloc() and free() by functions that do not know about these 532555714Skris additional arguments. To register and find out the current 532655714Skris settings for extended allocation functions, the following 532755714Skris functions are provided: 532855714Skris 532955714Skris CRYPTO_set_mem_ex_functions 533055714Skris CRYPTO_set_locked_mem_ex_functions 533155714Skris CRYPTO_get_mem_ex_functions 533255714Skris CRYPTO_get_locked_mem_ex_functions 533355714Skris 533455714Skris These work the same way as CRYPTO_set_mem_functions and friends. 533555714Skris CRYPTO_get_[locked_]mem_functions now writes 0 where such an 533655714Skris extended allocation function is enabled. 533755714Skris Similarly, CRYPTO_get_[locked_]mem_ex_functions writes 0 where 533855714Skris a conventional allocation function is enabled. 533955714Skris [Richard Levitte, Bodo Moeller] 534055714Skris 534155714Skris *) Finish off removing the remaining LHASH function pointer casts. 534255714Skris There should no longer be any prototype-casting required when using 534355714Skris the LHASH abstraction, and any casts that remain are "bugs". See 534455714Skris the callback types and macros at the head of lhash.h for details 534555714Skris (and "OBJ_cleanup" in crypto/objects/obj_dat.c as an example). 534655714Skris [Geoff Thorpe] 534755714Skris 534855714Skris *) Add automatic query of EGD sockets in RAND_poll() for the unix variant. 534955714Skris If /dev/[u]random devices are not available or do not return enough 535055714Skris entropy, EGD style sockets (served by EGD or PRNGD) will automatically 535155714Skris be queried. 535255714Skris The locations /var/run/egd-pool, /dev/egd-pool, /etc/egd-pool, and 535355714Skris /etc/entropy will be queried once each in this sequence, quering stops 535455714Skris when enough entropy was collected without querying more sockets. 535555714Skris [Lutz Jaenicke] 535655714Skris 535755714Skris *) Change the Unix RAND_poll() variant to be able to poll several 535855714Skris random devices, as specified by DEVRANDOM, until a sufficient amount 535955714Skris of data has been collected. We spend at most 10 ms on each file 536055714Skris (select timeout) and read in non-blocking mode. DEVRANDOM now 536155714Skris defaults to the list "/dev/urandom", "/dev/random", "/dev/srandom" 536255714Skris (previously it was just the string "/dev/urandom"), so on typical 536355714Skris platforms the 10 ms delay will never occur. 536455714Skris Also separate out the Unix variant to its own file, rand_unix.c. 536555714Skris For VMS, there's a currently-empty rand_vms.c. 536655714Skris [Richard Levitte] 536755714Skris 536855714Skris *) Move OCSP client related routines to ocsp_cl.c. These 536955714Skris provide utility functions which an application needing 537055714Skris to issue a request to an OCSP responder and analyse the 537155714Skris response will typically need: as opposed to those which an 537255714Skris OCSP responder itself would need which will be added later. 537355714Skris 537455714Skris OCSP_request_sign() signs an OCSP request with an API similar 537555714Skris to PKCS7_sign(). OCSP_response_status() returns status of OCSP 537655714Skris response. OCSP_response_get1_basic() extracts basic response 537755714Skris from response. OCSP_resp_find_status(): finds and extracts status 537855714Skris information from an OCSP_CERTID structure (which will be created 537955714Skris when the request structure is built). These are built from lower 538055714Skris level functions which work on OCSP_SINGLERESP structures but 538155714Skris wont normally be used unless the application wishes to examine 538255714Skris extensions in the OCSP response for example. 538355714Skris 538455714Skris Replace nonce routines with a pair of functions. 538555714Skris OCSP_request_add1_nonce() adds a nonce value and optionally 538655714Skris generates a random value. OCSP_check_nonce() checks the 538755714Skris validity of the nonce in an OCSP response. 538855714Skris [Steve Henson] 538955714Skris 539055714Skris *) Change function OCSP_request_add() to OCSP_request_add0_id(). 539155714Skris This doesn't copy the supplied OCSP_CERTID and avoids the 539255714Skris need to free up the newly created id. Change return type 539355714Skris to OCSP_ONEREQ to return the internal OCSP_ONEREQ structure. 539455714Skris This can then be used to add extensions to the request. 539555714Skris Deleted OCSP_request_new(), since most of its functionality 539655714Skris is now in OCSP_REQUEST_new() (and the case insensitive name 539755714Skris clash) apart from the ability to set the request name which 539855714Skris will be added elsewhere. 539955714Skris [Steve Henson] 540055714Skris 540155714Skris *) Update OCSP API. Remove obsolete extensions argument from 540255714Skris various functions. Extensions are now handled using the new 540355714Skris OCSP extension code. New simple OCSP HTTP function which 540455714Skris can be used to send requests and parse the response. 540555714Skris [Steve Henson] 540655714Skris 540755714Skris *) Fix the PKCS#7 (S/MIME) code to work with new ASN1. Two new 540855714Skris ASN1_ITEM structures help with sign and verify. PKCS7_ATTR_SIGN 540955714Skris uses the special reorder version of SET OF to sort the attributes 541055714Skris and reorder them to match the encoded order. This resolves a long 541155714Skris standing problem: a verify on a PKCS7 structure just after signing 541255714Skris it used to fail because the attribute order did not match the 541355714Skris encoded order. PKCS7_ATTR_VERIFY does not reorder the attributes: 541455714Skris it uses the received order. This is necessary to tolerate some broken 541555714Skris software that does not order SET OF. This is handled by encoding 541655714Skris as a SEQUENCE OF but using implicit tagging (with UNIVERSAL class) 541755714Skris to produce the required SET OF. 541855714Skris [Steve Henson] 541955714Skris 542055714Skris *) Have mk1mf.pl generate the macros OPENSSL_BUILD_SHLIBCRYPTO and 542155714Skris OPENSSL_BUILD_SHLIBSSL and use them appropriately in the header 542255714Skris files to get correct declarations of the ASN.1 item variables. 542355714Skris [Richard Levitte] 542455714Skris 542555714Skris *) Rewrite of PKCS#12 code to use new ASN1 functionality. Replace many 542655714Skris PKCS#12 macros with real functions. Fix two unrelated ASN1 bugs: 542755714Skris asn1_check_tlen() would sometimes attempt to use 'ctx' when it was 542855714Skris NULL and ASN1_TYPE was not dereferenced properly in asn1_ex_c2i(). 542955714Skris New ASN1 macro: DECLARE_ASN1_ITEM() which just declares the relevant 543055714Skris ASN1_ITEM and no wrapper functions. 543155714Skris [Steve Henson] 543255714Skris 543355714Skris *) New functions or ASN1_item_d2i_fp() and ASN1_item_d2i_bio(). These 543455714Skris replace the old function pointer based I/O routines. Change most of 543555714Skris the *_d2i_bio() and *_d2i_fp() functions to use these. 543655714Skris [Steve Henson] 543755714Skris 543855714Skris *) Enhance mkdef.pl to be more accepting about spacing in C preprocessor 543955714Skris lines, recognice more "algorithms" that can be deselected, and make 544055714Skris it complain about algorithm deselection that isn't recognised. 544155714Skris [Richard Levitte] 544255714Skris 544355714Skris *) New ASN1 functions to handle dup, sign, verify, digest, pack and 544455714Skris unpack operations in terms of ASN1_ITEM. Modify existing wrappers 544555714Skris to use new functions. Add NO_ASN1_OLD which can be set to remove 544655714Skris some old style ASN1 functions: this can be used to determine if old 544755714Skris code will still work when these eventually go away. 544855714Skris [Steve Henson] 544955714Skris 545055714Skris *) New extension functions for OCSP structures, these follow the 545155714Skris same conventions as certificates and CRLs. 545255714Skris [Steve Henson] 545355714Skris 545455714Skris *) New function X509V3_add1_i2d(). This automatically encodes and 545555714Skris adds an extension. Its behaviour can be customised with various 545655714Skris flags to append, replace or delete. Various wrappers added for 545755714Skris certifcates and CRLs. 545855714Skris [Steve Henson] 545955714Skris 546055714Skris *) Fix to avoid calling the underlying ASN1 print routine when 546155714Skris an extension cannot be parsed. Correct a typo in the 546255714Skris OCSP_SERVICELOC extension. Tidy up print OCSP format. 546355714Skris [Steve Henson] 546455714Skris 546555714Skris *) Make mkdef.pl parse some of the ASN1 macros and add apropriate 546655714Skris entries for variables. 546755714Skris [Steve Henson] 546855714Skris 546955714Skris *) Add functionality to apps/openssl.c for detecting locking 547055714Skris problems: As the program is single-threaded, all we have 547155714Skris to do is register a locking callback using an array for 547255714Skris storing which locks are currently held by the program. 547355714Skris [Bodo Moeller] 547455714Skris 547555714Skris *) Use a lock around the call to CRYPTO_get_ex_new_index() in 547655714Skris SSL_get_ex_data_X509_STORE_idx(), which is used in 547755714Skris ssl_verify_cert_chain() and thus can be called at any time 547855714Skris during TLS/SSL handshakes so that thread-safety is essential. 547955714Skris Unfortunately, the ex_data design is not at all suited 548055714Skris for multi-threaded use, so it probably should be abolished. 548155714Skris [Bodo Moeller] 548255714Skris 548355714Skris *) Added Broadcom "ubsec" ENGINE to OpenSSL. 548455714Skris [Broadcom, tweaked and integrated by Geoff Thorpe] 548555714Skris 548655714Skris *) Move common extension printing code to new function 548755714Skris X509V3_print_extensions(). Reorganise OCSP print routines and 548855714Skris implement some needed OCSP ASN1 functions. Add OCSP extensions. 548955714Skris [Steve Henson] 549055714Skris 549155714Skris *) New function X509_signature_print() to remove duplication in some 549255714Skris print routines. 549355714Skris [Steve Henson] 549455714Skris 549555714Skris *) Add a special meaning when SET OF and SEQUENCE OF flags are both 549655714Skris set (this was treated exactly the same as SET OF previously). This 549755714Skris is used to reorder the STACK representing the structure to match the 549855714Skris encoding. This will be used to get round a problem where a PKCS7 549955714Skris structure which was signed could not be verified because the STACK 550055714Skris order did not reflect the encoded order. 550155714Skris [Steve Henson] 550255714Skris 550355714Skris *) Reimplement the OCSP ASN1 module using the new code. 550455714Skris [Steve Henson] 550555714Skris 550655714Skris *) Update the X509V3 code to permit the use of an ASN1_ITEM structure 550755714Skris for its ASN1 operations. The old style function pointers still exist 550855714Skris for now but they will eventually go away. 550955714Skris [Steve Henson] 551055714Skris 551155714Skris *) Merge in replacement ASN1 code from the ASN1 branch. This almost 551255714Skris completely replaces the old ASN1 functionality with a table driven 551355714Skris encoder and decoder which interprets an ASN1_ITEM structure describing 551455714Skris the ASN1 module. Compatibility with the existing ASN1 API (i2d,d2i) is 551555714Skris largely maintained. Almost all of the old asn1_mac.h macro based ASN1 551655714Skris has also been converted to the new form. 551755714Skris [Steve Henson] 551855714Skris 551955714Skris *) Change BN_mod_exp_recp so that negative moduli are tolerated 552055714Skris (the sign is ignored). Similarly, ignore the sign in BN_MONT_CTX_set 552155714Skris so that BN_mod_exp_mont and BN_mod_exp_mont_word work 552255714Skris for negative moduli. 552355714Skris [Bodo Moeller] 552455714Skris 552555714Skris *) Fix BN_uadd and BN_usub: Always return non-negative results instead 552655714Skris of not touching the result's sign bit. 552755714Skris [Bodo Moeller] 552855714Skris 552955714Skris *) BN_div bugfix: If the result is 0, the sign (res->neg) must not be 553055714Skris set. 553155714Skris [Bodo Moeller] 553255714Skris 553355714Skris *) Changed the LHASH code to use prototypes for callbacks, and created 553455714Skris macros to declare and implement thin (optionally static) functions 553555714Skris that provide type-safety and avoid function pointer casting for the 553655714Skris type-specific callbacks. 553755714Skris [Geoff Thorpe] 553855714Skris 553955714Skris *) Added Kerberos Cipher Suites to be used with TLS, as written in 554055714Skris RFC 2712. 554155714Skris [Veers Staats <staatsvr@asc.hpc.mil>, 554255714Skris Jeffrey Altman <jaltman@columbia.edu>, via Richard Levitte] 554355714Skris 554455714Skris *) Reformat the FAQ so the different questions and answers can be divided 554555714Skris in sections depending on the subject. 554655714Skris [Richard Levitte] 554755714Skris 554855714Skris *) Have the zlib compression code load ZLIB.DLL dynamically under 554955714Skris Windows. 555055714Skris [Richard Levitte] 555155714Skris 555255714Skris *) New function BN_mod_sqrt for computing square roots modulo a prime 555355714Skris (using the probabilistic Tonelli-Shanks algorithm unless 555455714Skris p == 3 (mod 4) or p == 5 (mod 8), which are cases that can 555555714Skris be handled deterministically). 555655714Skris [Lenka Fibikova <fibikova@exp-math.uni-essen.de>, Bodo Moeller] 555755714Skris 555855714Skris *) Make BN_mod_inverse faster by explicitly handling small quotients 555955714Skris in the Euclid loop.

The modifications described in 562755714Skris it do *not* apply to OpenSSL 0.9.7. 562855714Skris 562955714Skris *) Remove a few calls to bn_wexpand() in BN_sqr() (the one in there 563055714Skris was actually never needed) and in BN_mul(). The removal in BN_mul() 563155714Skris required a small change in bn_mul_part_recursive() and the addition 563255714Skris of the functions bn_cmp_part_words(), bn_sub_part_words() and 563355714Skris bn_add_part_words(), which do the same thing as bn_cmp_words(), 563455714Skris bn_sub_words() and bn_add_words() except they take arrays with 563555714Skris differing sizes. 563655714Skris [Richard Levitte] 563755714Skris#endif 563855714Skris 563955714Skris *) In 'openssl passwd', verify passwords read from the terminal 564055714Skris unless the '-salt' option is used (which usually means that 564155714Skris verification would just waste user's time since the resulting 564255714Skris hash is going to be compared with some given password hash) 564355714Skris or the new '-noverify' option is used. 564455714Skris 564555714Skris This is an incompatible change, but it does not affect 564655714Skris non-interactive use of 'openssl passwd' (passwords on the command 564755714Skris line, '-stdin' option, '-in ...' option) and thus should not 564855714Skris cause any problems. 564955714Skris [Bodo Moeller] 565055714Skris 565155714Skris *) Remove all references to RSAref, since there's no more need for it. 565255714Skris [Richard Levitte] 565355714Skris 565455714Skris *) Make DSO load along a path given through an environment variable 565555714Skris (SHLIB_PATH) with shl_load(). 565655714Skris [Richard Levitte] 565755714Skris 565855714Skris *) Constify the ENGINE code as a result of BIGNUM constification. 565955714Skris Also constify the RSA code and most things related to it. In a 566055714Skris few places, most notable in the depth of the ASN.1 code, ugly 566155714Skris casts back to non-const were required (to be solved at a later 566255714Skris time) 566355714Skris [Richard Levitte] 566455714Skris 566555714Skris *) Make it so the openssl application has all engines loaded by default. 566655714Skris [Richard Levitte] 566755714Skris 566855714Skris *) Constify the BIGNUM routines a little more. 566955714Skris [Richard Levitte] 567055714Skris 567155714Skris *) Add the following functions: 567255714Skris 567355714Skris ENGINE_load_cswift() 567455714Skris ENGINE_load_chil() 567555714Skris ENGINE_load_atalla() 567655714Skris ENGINE_load_nuron() 567755714Skris ENGINE_load_builtin_engines() 567855714Skris 567955714Skris That way, an application can itself choose if external engines that 568055714Skris are built-in in OpenSSL shall ever be used or not. The benefit is 568155714Skris that applications won't have to be linked with libdl or other dso 568255714Skris libraries unless it's really needed. 568355714Skris 568455714Skris Changed 'openssl engine' to load all engines on demand. 568555714Skris Changed the engine header files to avoid the duplication of some 568655714Skris declarations (they differed!). 568755714Skris [Richard Levitte] 568855714Skris 568955714Skris *) 'openssl engine' can now list capabilities. 569055714Skris [Richard Levitte] 569155714Skris 569255714Skris *) Better error reporting in 'openssl engine'. 569355714Skris [Richard Levitte] 569455714Skris 569555714Skris *) Never call load_dh_param(NULL) in s_server. 569655714Skris [Bodo Moeller] 569755714Skris 569855714Skris *) Add engine application. It can currently list engines by name and 569955714Skris identity, and test if they are actually available. 570055714Skris [Richard Levitte] 570155714Skris 570255714Skris *) Improve RPM specification file by forcing symbolic linking and making 570355714Skris sure the installed documentation is also owned by root.root. 570455714Skris [Damien Miller <djm@mindrot.org>] 570555714Skris 570655714Skris *) Give the OpenSSL applications more possibilities to make use of 570755714Skris keys (public as well as private) handled by engines. 570855714Skris [Richard Levitte] 570955714Skris 571055714Skris *) Add OCSP code that comes from CertCo. 571155714Skris [Richard Levitte] 571255714Skris 571355714Skris *) Add VMS support for the Rijndael code. 571455714Skris [Richard Levitte] 571555714Skris 571655714Skris *) Added untested support for Nuron crypto accelerator. 571755714Skris [Ben Laurie] 571855714Skris 571955714Skris *) Add support for external cryptographic devices. This code was 572055714Skris previously distributed separately as the "engine" branch. 572155714Skris [Geoff Thorpe, Richard Levitte] 572255714Skris 572355714Skris *) Rework the filename-translation in the DSO code. It is now possible to 572455714Skris have far greater control over how a "name" is turned into a filename 572555714Skris depending on the operating environment and any oddities about the 572655714Skris different shared library filenames on each system. 572755714Skris [Geoff Thorpe] 572855714Skris 572955714Skris *) Support threads on FreeBSD-elf in Configure. 573055714Skris [Richard Levitte] 573155714Skris 573255714Skris *) Fix for SHA1 assembly problem with MASM: it produces 573355714Skris warnings about corrupt line number information when assembling 573455714Skris with debugging information. This is caused by the overlapping 573555714Skris of two sections. 573655714Skris [Bernd Matthes <mainbug@celocom.de>, Steve Henson] 573755714Skris 573855714Skris *) NCONF changes. 573955714Skris NCONF_get_number() has no error checking at all. As a replacement, 574055714Skris NCONF_get_number_e() is defined (_e for "error checking") and is 574155714Skris promoted strongly. The old NCONF_get_number is kept around for 574255714Skris binary backward compatibility. 574355714Skris Make it possible for methods to load from something other than a BIO, 574455714Skris by providing a function pointer that is given a name instead of a BIO. 574555714Skris For example, this could be used to load configuration data from an 574655714Skris LDAP server. 574755714Skris [Richard Levitte] 574855714Skris 574955714Skris *) Fix for non blocking accept BIOs. Added new I/O special reason 575055714Skris BIO_RR_ACCEPT to cover this case. Previously use of accept BIOs 575155714Skris with non blocking I/O was not possible because no retry code was 575255714Skris implemented. Also added new SSL code SSL_WANT_ACCEPT to cover 575355714Skris this case. 575455714Skris [Steve Henson] 575555714Skris 575655714Skris *) Added the beginnings of Rijndael support. 575755714Skris [Ben Laurie] 575855714Skris 575955714Skris *) Fix for bug in DirectoryString mask setting. Add support for 576055714Skris X509_NAME_print_ex() in 'req' and X509_print_ex() function 576155714Skris to allow certificate printing to more controllable, additional 576255714Skris 'certopt' option to 'x509' to allow new printing options to be 576355714Skris set. 576455714Skris [Steve Henson] 576555714Skris 576655714Skris *) Clean old EAY MD5 hack from e_os.h. 576755714Skris [Richard Levitte] 576855714Skris 576955714Skris Changes between 0.9.6l and 0.9.6m [17 Mar 2004] 577055714Skris 577155714Skris *) Fix null-pointer assignment in do_change_cipher_spec() revealed 577255714Skris by using the Codenomicon TLS Test Tool (CVE-2004-0079) 577355714Skris [Joe Orton, Steve Henson] 577455714Skris 577555714Skris Changes between 0.9.6k and 0.9.6l [04 Nov 2003] 577655714Skris 577755714Skris *) Fix additional bug revealed by the NISCC test suite: 577855714Skris 577955714Skris Stop bug triggering large recursion when presented with 578055714Skris certain ASN.1 tags (CVE-2003-0851) 578155714Skris [Steve Henson] 578255714Skris 578355714Skris Changes between 0.9.6j and 0.9.6k [30 Sep 2003] 578455714Skris 578555714Skris *) Fix various bugs revealed by running the NISCC test suite: 578655714Skris 578755714Skris Stop out of bounds reads in the ASN1 code when presented with 578855714Skris invalid tags (CVE-2003-0543 and CVE-2003-0544). 578955714Skris 579055714Skris If verify callback ignores invalid public key errors don't try to check 579155714Skris certificate signature with the NULL public key. 579255714Skris 579355714Skris [Steve Henson] 579455714Skris 579555714Skris *) In ssl3_accept() (ssl/s3_srvr.c) only accept a client certificate 579655714Skris if the server requested one: as stated in TLS 1.0 and SSL 3.0 579755714Skris specifications. 579855714Skris [Steve Henson] 579955714Skris 580055714Skris *) In ssl3_get_client_hello() (ssl/s3_srvr.c), tolerate additional 580155714Skris extra data after the compression methods not only for TLS 1.0 580255714Skris but also for SSL 3.0 (as required by the specification). 580355714Skris [Bodo Moeller; problem pointed out by Matthias Loepfe] 580455714Skris 580555714Skris *) Change X509_certificate_type() to mark the key as exported/exportable 580655714Skris when it's 512 *bits* long, not 512 bytes. 580755714Skris [Richard Levitte] 580855714Skris 580955714Skris Changes between 0.9.6i and 0.9.6j [10 Apr 2003] 581055714Skris 581155714Skris *) Countermeasure against the Klima-Pokorny-Rosa extension of 581255714Skris Bleichbacher's attack on PKCS #1 v1.5 padding: treat 581355714Skris a protocol version number mismatch like a decryption error 581455714Skris in ssl3_get_client_key_exchange (ssl/s3_srvr.c). 581555714Skris [Bodo Moeller] 581655714Skris 581755714Skris *) Turn on RSA blinding by default in the default implementation 581855714Skris to avoid a timing attack. Applications that don't want it can call 581955714Skris RSA_blinding_off() or use the new flag RSA_FLAG_NO_BLINDING. 582055714Skris They would be ill-advised to do so in most cases. 582155714Skris [Ben Laurie, Steve Henson, Geoff Thorpe, Bodo Moeller] 582255714Skris 582355714Skris *) Change RSA blinding code so that it works when the PRNG is not 582455714Skris seeded (in this case, the secret RSA exponent is abused as 582555714Skris an unpredictable seed -- if it is not unpredictable, there 582655714Skris is no point in blinding anyway). Make RSA blinding thread-safe 582755714Skris by remembering the creator's thread ID in rsa->blinding and 582855714Skris having all other threads use local one-time blinding factors 582955714Skris (this requires more computation than sharing rsa->blinding, but 583055714Skris avoids excessive locking; and if an RSA object is not shared 583155714Skris between threads, blinding will still be very fast). 583255714Skris [Bodo Moeller] 583355714Skris 583455714Skris Changes between 0.9.6h and 0.9.6i [19 Feb 2003] 583555714Skris 583655714Skris *) In ssl3_get_record (ssl/s3_pkt.c), minimize information leaked 583755714Skris via timing by performing a MAC computation even if incorrrect 583855714Skris block cipher padding has been found. This is a countermeasure 583955714Skris against active attacks where the attacker has to distinguish 584055714Skris between bad padding and a MAC verification error.

This is done with a counter that will 585055714Skris place alternating values in each byte.

Saarinen <markku-juhani.saarinen@nokia.com>: 6357 PRNG state recovery was possible based on the output of 6358 one PRNG request appropriately sized to gain knowledge on 6359 'md' followed by enough consecutive 1-byte PRNG requests 6360 to traverse all of 'state'. 6361 6362 1. When updating 'md_local' (the current thread's copy of 'md') 6363 during PRNG output generation, hash all of the previous 6364 'md_local' value, not just the half used for PRNG output. 6365 6366 2. Make the number of bytes from 'state' included into the hash 6367 independent from the number of PRNG bytes requested. 6368 6369 The first measure alone would be sufficient to avoid 6370 Markku-Juhani's attack. (Actually it had never occurred 6371 to me that the half of 'md_local' used for chaining was the 6372 half from which PRNG output bytes were taken -- I had always 6373 assumed that the secret half would be used.) The second 6374 measure makes sure that additional data from 'state' is never 6375 mixed into 'md_local' in small portions; this heuristically 6376 further strengthens the PRNG. 6377 [Bodo Moeller] 6378 6379 *) Fix crypto/bn/asm/mips3.s. 6380 [Andy Polyakov] 6381 6382 *) When only the key is given to "enc", the IV is undefined.

(Note that the attack is impractical against 6409 SSL 3.0 and TLS 1.0 anyway because length and version checking 6410 means that the probability of guessing a valid ciphertext is 6411 around 2^-40; see section 5 in Bleichenbacher's CRYPTO '98 6412 paper.) 6413 6414 Before 0.9.5, the countermeasure (hide the error by generating a 6415 random 'decryption result') did not work properly because 6416 ERR_clear_error() was missing, meaning that SSL_get_error() would 6417 detect the supposedly ignored error. 6418 6419 Both problems are now fixed. 6420 [Bodo Moeller] 6421 6422 *) In crypto/bio/bf_buff.c, increase DEFAULT_BUFFER_SIZE to 4096 6423 (previously it was 1024). 6424 [Bodo Moeller] 6425 6426 *) Fix for compatibility mode trust settings: ignore trust settings 6427 unless some valid trust or reject settings are present. 6428 [Steve Henson] 6429 6430 *) Fix for blowfish EVP: its a variable length cipher. 6431 [Steve Henson] 6432 6433 *) Fix various bugs related to DSA S/MIME verification.

This has 6441 caused some confusion to Windows users who haven't defined $HOME. 6442 Thus RAND_file_name() is changed again: e_os.h can define a 6443 DEFAULT_HOME, which will be used if $HOME is not set. 6444 For Windows, we use "C:"; on other platforms, we still require 6445 environment variables. 6446 6447 *) Move 'if (!initialized) RAND_poll()' into regions protected by 6448 CRYPTO_LOCK_RAND.

Also, make the perl 6471 scripts that use symlink() to test if it really exists and use "cp" 6472 if it doesn't. All this made OpenSSL compilable and installable in 6473 CygWin. 6474 [Richard Levitte] 6475 6476 *) Fix for asn1_GetSequence() for indefinite length constructed data. 6477 If SEQUENCE is length is indefinite just set c->slen to the total 6478 amount of data available. 6479 [Steve Henson, reported by shige@FreeBSD.org] 6480 [This change does not apply to 0.9.7.] 6481 6482 *) Change bctest to avoid here-documents inside command substitution 6483 (workaround for FreeBSD /bin/sh bug). 6484 For compatibility with Ultrix, avoid shell functions (introduced 6485 in the bctest version that searches along $PATH). 6486 [Bodo Moeller] 6487 6488 *) Rename 'des_encrypt' to 'des_encrypt1'.

Count how many times MemCheck_off() has been called so that 6555 nested use can be treated correctly. This also avoids 6556 inband-signalling in the previous code (which relied on the 6557 assumption that thread ID 0 is impossible). 6558 [Bodo Moeller] 6559 6560 *) Add "-rand" option also to s_client and s_server. 6561 [Lutz Jaenicke] 6562 6563 *) Fix CPU detection on Irix 6.x. 6564 [Kurt Hockenbury <khockenb@stevens-tech.edu> and 6565 "Bruce W.

Also make 6603 sure BIO's that break lines after each write do not create invalid 6604 headers. 6605 [Richard Levitte] 6606 6607 *) Make the CRL encoding routines work with empty SEQUENCE OF. The 6608 macros previously used would not encode an empty SEQUENCE OF 6609 and break the signature. 6610 [Steve Henson] 6611 [This change does not apply to 0.9.7.] 6612 6613 *) Zero the premaster secret after deriving the master secret in 6614 DH ciphersuites. 6615 [Steve Henson] 6616 6617 *) Add some EVP_add_digest_alias registrations (as found in 6618 OpenSSL_add_all_digests()) to SSL_library_init() 6619 aka OpenSSL_add_ssl_algorithms(). This provides improved 6620 compatibility with peers using X.509 certificates 6621 with unconventional AlgorithmIdentifier OIDs. 6622 [Bodo Moeller] 6623 6624 *) Fix for Irix with NO_ASM. 6625 ["Bruce W.

This was done 6636 by adding an extra length parameter to asc2uni(). 6637 [Steve Henson, reported by <oddissey@samsung.co.kr>] 6638 6639 *) Fix C code generated by 'openssl dsaparam -C': If a BN_bin2bn 6640 call failed, free the DSA structure. 6641 [Bodo Moeller] 6642 6643 *) Fix to uni2asc() to cope with zero length Unicode strings. 6644 These are present in some PKCS#12 files. 6645 [Steve Henson] 6646 6647 *) Increase s2->wbuf allocation by one byte in ssl2_new (ssl/s2_lib.c). 6648 Otherwise do_ssl_write (ssl/s2_pkt.c) will write beyond buffer limits 6649 when writing a 32767 byte record. 6650 [Bodo Moeller; problem reported by Eric Day <eday@concentric.net>] 6651 6652 *) In RSA_eay_public_{en,ed}crypt and RSA_eay_mod_exp (rsa_eay.c), 6653 obtain lock CRYPTO_LOCK_RSA before setting rsa->_method_mod_{n,p,q}. 6654 6655 (RSA objects have a reference count access to which is protected 6656 by CRYPTO_LOCK_RSA [see rsa_lib.c, s3_srvr.c, ssl_cert.c, ssl_rsa.c], 6657 so they are meant to be shared between threads.) 6658 [Bodo Moeller, Geoff Thorpe; original patch submitted by 6659 "Reddie, Steven" <Steven.Reddie@ca.com>] 6660 6661 *) Fix a deadlock in CRYPTO_mem_leaks(). 6662 [Bodo Moeller] 6663 6664 *) Use better test patterns in bntest. 6665 [Ulf M�ller] 6666 6667 *) rand_win.c fix for Borland C. 6668 [Ulf M�ller] 6669 6670 *) BN_rshift bugfix for n == 0. 6671 [Bodo Moeller] 6672 6673 *) Add a 'bctest' script that checks for some known 'bc' bugs 6674 so that 'make test' does not abort just because 'bc' is broken. 6675 [Bodo Moeller] 6676 6677 *) Store verify_result within SSL_SESSION also for client side to 6678 avoid potential security hole. (Re-used sessions on the client side 6679 always resulted in verify_result==X509_V_OK, not using the original 6680 result of the server certificate verification.) 6681 [Lutz Jaenicke] 6682 6683 *) Fix ssl3_pending: If the record in s->s3->rrec is not of type 6684 SSL3_RT_APPLICATION_DATA, return 0. 6685 Similarly, change ssl2_pending to return 0 if SSL_in_init(s) is true. 6686 [Bodo Moeller] 6687 6688 *) Fix SSL_peek: 6689 Both ssl2_peek and ssl3_peek, which were totally broken in earlier 6690 releases, have been re-implemented by renaming the previous 6691 implementations of ssl2_read and ssl3_read to ssl2_read_internal 6692 and ssl3_read_internal, respectively, and adding 'peek' parameters 6693 to them. The new ssl[23]_{read,peek} functions are calls to 6694 ssl[23]_read_internal with the 'peek' flag set appropriately. 6695 A 'peek' parameter has also been added to ssl3_read_bytes, which 6696 does the actual work for ssl3_read_internal. 6697 [Bodo Moeller] 6698 6699 *) Initialise "ex_data" member of RSA/DSA/DH structures prior to calling 6700 the method-specific "init()" handler. Also clean up ex_data after 6701 calling the method-specific "finish()" handler. Previously, this was 6702 happening the other way round. 6703 [Geoff Thorpe] 6704 6705 *) Increase BN_CTX_NUM (the number of BIGNUMs in a BN_CTX) to 16. 6706 The previous value, 12, was not always sufficient for BN_mod_exp(). 6707 [Bodo Moeller] 6708 6709 *) Make sure that shared libraries get the internal name engine with 6710 the full version number and not just 0. This should mark the 6711 shared libraries as not backward compatible. Of course, this should 6712 be changed again when we can guarantee backward binary compatibility. 6713 [Richard Levitte] 6714 6715 *) Fix typo in get_cert_by_subject() in by_dir.c 6716 [Jean-Marc Desperrier <jean-marc.desperrier@certplus.com>] 6717 6718 *) Rework the system to generate shared libraries: 6719 6720 - Make note of the expected extension for the shared libraries and 6721 if there is a need for symbolic links from for example libcrypto.so.0 6722 to libcrypto.so.0.9.7. There is extended info in Configure for 6723 that. 6724 6725 - Make as few rebuilds of the shared libraries as possible. 6726 6727 - Still avoid linking the OpenSSL programs with the shared libraries. 6728 6729 - When installing, install the shared libraries separately from the 6730 static ones. 6731 [Richard Levitte] 6732 6733 *) Fix SSL_CTX_set_read_ahead macro to actually use its argument. 6734 6735 Copy SSL_CTX's read_ahead flag to SSL object directly in SSL_new 6736 and not in SSL_clear because the latter is also used by the 6737 accept/connect functions; previously, the settings made by 6738 SSL_set_read_ahead would be lost during the handshake. 6739 [Bodo Moeller; problems reported by Anders Gertz <gertz@epact.se>] 6740 6741 *) Correct util/mkdef.pl to be selective about disabled algorithms. 6742 Previously, it would create entries for disableed algorithms no 6743 matter what. 6744 [Richard Levitte] 6745 6746 *) Added several new manual pages for SSL_* function. 6747 [Lutz Jaenicke] 6748 6749 Changes between 0.9.5a and 0.9.6 [24 Sep 2000] 6750 6751 *) In ssl23_get_client_hello, generate an error message when faced 6752 with an initial SSL 3.0/TLS record that is too small to contain the 6753 first two bytes of the ClientHello message, i.e. client_version. 6754 (Note that this is a pathologic case that probably has never happened 6755 in real life.) The previous approach was to use the version number 6756 from the record header as a substitute; but our protocol choice 6757 should not depend on that one because it is not authenticated 6758 by the Finished messages. 6759 [Bodo Moeller] 6760 6761 *) More robust randomness gathering functions for Windows. 6762 [Jeffrey Altman <jaltman@columbia.edu>] 6763 6764 *) For compatibility reasons if the flag X509_V_FLAG_ISSUER_CHECK is 6765 not set then we don't setup the error code for issuer check errors 6766 to avoid possibly overwriting other errors which the callback does 6767 handle. If an application does set the flag then we assume it knows 6768 what it is doing and can handle the new informational codes 6769 appropriately. 6770 [Steve Henson] 6771 6772 *) Fix for a nasty bug in ASN1_TYPE handling. ASN1_TYPE is used for 6773 a general "ANY" type, as such it should be able to decode anything 6774 including tagged types. However it didn't check the class so it would 6775 wrongly interpret tagged types in the same way as their universal 6776 counterpart and unknown types were just rejected. Changed so that the 6777 tagged and unknown types are handled in the same way as a SEQUENCE: 6778 that is the encoding is stored intact. There is also a new type 6779 "V_ASN1_OTHER" which is used when the class is not universal, in this 6780 case we have no idea what the actual type is so we just lump them all 6781 together. 6782 [Steve Henson] 6783 6784 *) On VMS, stdout may very well lead to a file that is written to 6785 in a record-oriented fashion. That means that every write() will 6786 write a separate record, which will be read separately by the 6787 programs trying to read from it. This can be very confusing. 6788 6789 The solution is to put a BIO filter in the way that will buffer 6790 text until a linefeed is reached, and then write everything a 6791 line at a time, so every record written will be an actual line, 6792 not chunks of lines and not (usually doesn't happen, but I've 6793 seen it once) several lines in one record. BIO_f_linebuffer() is 6794 the answer. 6795 6796 Currently, it's a VMS-only method, because that's where it has 6797 been tested well enough. 6798 [Richard Levitte] 6799 6800 *) Remove 'optimized' squaring variant in BN_mod_mul_montgomery, 6801 it can return incorrect results. 6802 (Note: The buggy variant was not enabled in OpenSSL 0.9.5a, 6803 but it was in 0.9.6-beta[12].) 6804 [Bodo Moeller] 6805 6806 *) Disable the check for content being present when verifying detached 6807 signatures in pk7_smime.c. Some versions of Netscape (wrongly) 6808 include zero length content when signing messages. 6809 [Steve Henson] 6810 6811 *) New BIO_shutdown_wr macro, which invokes the BIO_C_SHUTDOWN_WR 6812 BIO_ctrl (for BIO pairs). 6813 [Bodo M�ller] 6814 6815 *) Add DSO method for VMS. 6816 [Richard Levitte] 6817 6818 *) Bug fix: Montgomery multiplication could produce results with the 6819 wrong sign. 6820 [Ulf M�ller] 6821 6822 *) Add RPM specification openssl.spec and modify it to build three 6823 packages. The default package contains applications, application 6824 documentation and run-time libraries. The devel package contains 6825 include files, static libraries and function documentation. The 6826 doc package contains the contents of the doc directory. The original 6827 openssl.spec was provided by Damien Miller <djm@mindrot.org>. 6828 [Richard Levitte] 6829 6830 *) Add a large number of documentation files for many SSL routines. 6831 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>] 6832 6833 *) Add a configuration entry for Sony News 4. 6834 [NAKAJI Hiroyuki <nakaji@tutrp.tut.ac.jp>] 6835 6836 *) Don't set the two most significant bits to one when generating a 6837 random number < q in the DSA library. 6838 [Ulf M�ller] 6839 6840 *) New SSL API mode 'SSL_MODE_AUTO_RETRY'. This disables the default 6841 behaviour that SSL_read may result in SSL_ERROR_WANT_READ (even if 6842 the underlying transport is blocking) if a handshake took place. 6843 (The default behaviour is needed by applications such as s_client 6844 and s_server that use select() to determine when to use SSL_read; 6845 but for applications that know in advance when to expect data, it 6846 just makes things more complicated.) 6847 [Bodo Moeller] 6848 6849 *) Add RAND_egd_bytes(), which gives control over the number of bytes read 6850 from EGD. 6851 [Ben Laurie] 6852 6853 *) Add a few more EBCDIC conditionals that make `req' and `x509' 6854 work better on such systems. 6855 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] 6856 6857 *) Add two demo programs for PKCS12_parse() and PKCS12_create(). 6858 Update PKCS12_parse() so it copies the friendlyName and the 6859 keyid to the certificates aux info. 6860 [Steve Henson] 6861 6862 *) Fix bug in PKCS7_verify() which caused an infinite loop 6863 if there was more than one signature. 6864 [Sven Uszpelkat <su@celocom.de>] 6865 6866 *) Major change in util/mkdef.pl to include extra information 6867 about each symbol, as well as presentig variables as well 6868 as functions. This change means that there's n more need 6869 to rebuild the .num files when some algorithms are excluded. 6870 [Richard Levitte] 6871 6872 *) Allow the verify time to be set by an application, 6873 rather than always using the current time. 6874 [Steve Henson] 6875 6876 *) Phase 2 verify code reorganisation. The certificate 6877 verify code now looks up an issuer certificate by a 6878 number of criteria: subject name, authority key id 6879 and key usage. It also verifies self signed certificates 6880 by the same criteria. The main comparison function is 6881 X509_check_issued() which performs these checks. 6882 6883 Lot of changes were necessary in order to support this 6884 without completely rewriting the lookup code. 6885 6886 Authority and subject key identifier are now cached. 6887 6888 The LHASH 'certs' is X509_STORE has now been replaced 6889 by a STACK_OF(X509_OBJECT). This is mainly because an 6890 LHASH can't store or retrieve multiple objects with 6891 the same hash value. 6892 6893 As a result various functions (which were all internal 6894 use only) have changed to handle the new X509_STORE 6895 structure. This will break anything that messed round 6896 with X509_STORE internally. 6897 6898 The functions X509_STORE_add_cert() now checks for an 6899 exact match, rather than just subject name. 6900 6901 The X509_STORE API doesn't directly support the retrieval 6902 of multiple certificates matching a given criteria, however 6903 this can be worked round by performing a lookup first 6904 (which will fill the cache with candidate certificates) 6905 and then examining the cache for matches. This is probably 6906 the best we can do without throwing out X509_LOOKUP 6907 entirely (maybe later...). 6908 6909 The X509_VERIFY_CTX structure has been enhanced considerably. 6910 6911 All certificate lookup operations now go via a get_issuer() 6912 callback. Although this currently uses an X509_STORE it 6913 can be replaced by custom lookups. This is a simple way 6914 to bypass the X509_STORE hackery necessary to make this 6915 work and makes it possible to use more efficient techniques 6916 in future. A very simple version which uses a simple 6917 STACK for its trusted certificate store is also provided 6918 using X509_STORE_CTX_trusted_stack(). 6919 6920 The verify_cb() and verify() callbacks now have equivalents 6921 in the X509_STORE_CTX structure. 6922 6923 X509_STORE_CTX also has a 'flags' field which can be used 6924 to customise the verify behaviour. 6925 [Steve Henson] 6926 6927 *) Add new PKCS#7 signing option PKCS7_NOSMIMECAP which 6928 excludes S/MIME capabilities. 6929 [Steve Henson] 6930 6931 *) When a certificate request is read in keep a copy of the 6932 original encoding of the signed data and use it when outputing 6933 again. Signatures then use the original encoding rather than 6934 a decoded, encoded version which may cause problems if the 6935 request is improperly encoded. 6936 [Steve Henson] 6937 6938 *) For consistency with other BIO_puts implementations, call 6939 buffer_write(b, ...) directly in buffer_puts instead of calling 6940 BIO_write(b, ...). 6941 6942 In BIO_puts, increment b->num_write as in BIO_write. 6943 [Peter.Sylvester@EdelWeb.fr] 6944 6945 *) Fix BN_mul_word for the case where the word is 0. (We have to use 6946 BN_zero, we may not return a BIGNUM with an array consisting of 6947 words set to zero.) 6948 [Bodo Moeller] 6949 6950 *) Avoid calling abort() from within the library when problems are 6951 detected, except if preprocessor symbols have been defined 6952 (such as REF_CHECK, BN_DEBUG etc.). 6953 [Bodo Moeller] 6954 6955 *) New openssl application 'rsautl'. This utility can be 6956 used for low level RSA operations. DER public key 6957 BIO/fp routines also added. 6958 [Steve Henson] 6959 6960 *) New Configure entry and patches for compiling on QNX 4. 6961 [Andreas Schneider <andreas@ds3.etech.fh-hamburg.de>] 6962 6963 *) A demo state-machine implementation was sponsored by 6964 Nuron (http://www.nuron.com/) and is now available in 6965 demos/state_machine. 6966 [Ben Laurie] 6967 6968 *) New options added to the 'dgst' utility for signature 6969 generation and verification. 6970 [Steve Henson] 6971 6972 *) Unrecognized PKCS#7 content types are now handled via a 6973 catch all ASN1_TYPE structure. This allows unsupported 6974 types to be stored as a "blob" and an application can 6975 encode and decode it manually. 6976 [Steve Henson] 6977 6978 *) Fix various signed/unsigned issues to make a_strex.c 6979 compile under VC++. 6980 [Oscar Jacobsson <oscar.jacobsson@celocom.com>] 6981 6982 *) ASN1 fixes. i2d_ASN1_OBJECT was not returning the correct 6983 length if passed a buffer. ASN1_INTEGER_to_BN failed 6984 if passed a NULL BN and its argument was negative. 6985 [Steve Henson, pointed out by Sven Heiberg <sven@tartu.cyber.ee>] 6986 6987 *) Modification to PKCS#7 encoding routines to output definite 6988 length encoding. Since currently the whole structures are in 6989 memory there's not real point in using indefinite length 6990 constructed encoding. However if OpenSSL is compiled with 6991 the flag PKCS7_INDEFINITE_ENCODING the old form is used. 6992 [Steve Henson] 6993 6994 *) Added BIO_vprintf() and BIO_vsnprintf(). 6995 [Richard Levitte] 6996 6997 *) Added more prefixes to parse for in the the strings written 6998 through a logging bio, to cover all the levels that are available 6999 through syslog. The prefixes are now: 7000 7001 PANIC, EMERG, EMR => LOG_EMERG 7002 ALERT, ALR => LOG_ALERT 7003 CRIT, CRI => LOG_CRIT 7004 ERROR, ERR => LOG_ERR 7005 WARNING, WARN, WAR => LOG_WARNING 7006 NOTICE, NOTE, NOT => LOG_NOTICE 7007 INFO, INF => LOG_INFO 7008 DEBUG, DBG => LOG_DEBUG 7009 7010 and as before, if none of those prefixes are present at the 7011 beginning of the string, LOG_ERR is chosen. 7012 7013 On Win32, the LOG_* levels are mapped according to this: 7014 7015 LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR => EVENTLOG_ERROR_TYPE 7016 LOG_WARNING => EVENTLOG_WARNING_TYPE 7017 LOG_NOTICE, LOG_INFO, LOG_DEBUG => EVENTLOG_INFORMATION_TYPE 7018 7019 [Richard Levitte] 7020 7021 *) Made it possible to reconfigure with just the configuration 7022 argument "reconf" or "reconfigure". The command line arguments 7023 are stored in Makefile.ssl in the variable CONFIGURE_ARGS, 7024 and are retrieved from there when reconfiguring. 7025 [Richard Levitte] 7026 7027 *) MD4 implemented. 7028 [Assar Westerlund <assar@sics.se>, Richard Levitte] 7029 7030 *) Add the arguments -CAfile and -CApath to the pkcs12 utility. 7031 [Richard Levitte] 7032 7033 *) The obj_dat.pl script was messing up the sorting of object 7034 names. The reason was that it compared the quoted version 7035 of strings as a result "OCSP" > "OCSP Signing" because 7036 " > SPACE. Changed script to store unquoted versions of 7037 names and add quotes on output. It was also omitting some 7038 names from the lookup table if they were given a default 7039 value (that is if SN is missing it is given the same 7040 value as LN and vice versa), these are now added on the 7041 grounds that if an object has a name we should be able to 7042 look it up. Finally added warning output when duplicate 7043 short or long names are found. 7044 [Steve Henson] 7045 7046 *) Changes needed for Tandem NSK. 7047 [Scott Uroff <scott@xypro.com>] 7048 7049 *) Fix SSL 2.0 rollback checking: Due to an off-by-one error in 7050 RSA_padding_check_SSLv23(), special padding was never detected 7051 and thus the SSL 3.0/TLS 1.0 countermeasure against protocol 7052 version rollback attacks was not effective. 7053 7054 In s23_clnt.c, don't use special rollback-attack detection padding 7055 (RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the 7056 client; similarly, in s23_srvr.c, don't do the rollback check if 7057 SSL 2.0 is the only protocol enabled in the server. 7058 [Bodo Moeller] 7059 7060 *) Make it possible to get hexdumps of unprintable data with 'openssl 7061 asn1parse'. By implication, the functions ASN1_parse_dump() and 7062 BIO_dump_indent() are added. 7063 [Richard Levitte] 7064 7065 *) New functions ASN1_STRING_print_ex() and X509_NAME_print_ex() 7066 these print out strings and name structures based on various 7067 flags including RFC2253 support and proper handling of 7068 multibyte characters. Added options to the 'x509' utility 7069 to allow the various flags to be set. 7070 [Steve Henson] 7071 7072 *) Various fixes to use ASN1_TIME instead of ASN1_UTCTIME. 7073 Also change the functions X509_cmp_current_time() and 7074 X509_gmtime_adj() work with an ASN1_TIME structure, 7075 this will enable certificates using GeneralizedTime in validity 7076 dates to be checked. 7077 [Steve Henson] 7078 7079 *) Make the NEG_PUBKEY_BUG code (which tolerates invalid 7080 negative public key encodings) on by default, 7081 NO_NEG_PUBKEY_BUG can be set to disable it. 7082 [Steve Henson] 7083 7084 *) New function c2i_ASN1_OBJECT() which acts on ASN1_OBJECT 7085 content octets. An i2c_ASN1_OBJECT is unnecessary because 7086 the encoding can be trivially obtained from the structure. 7087 [Steve Henson] 7088 7089 *) crypto/err.c locking bugfix: Use write locks (CRYPTO_w_[un]lock), 7090 not read locks (CRYPTO_r_[un]lock). 7091 [Bodo Moeller] 7092 7093 *) A first attempt at creating official support for shared 7094 libraries through configuration. I've kept it so the 7095 default is static libraries only, and the OpenSSL programs 7096 are always statically linked for now, but there are 7097 preparations for dynamic linking in place. 7098 This has been tested on Linux and Tru64. 7099 [Richard Levitte] 7100 7101 *) Randomness polling function for Win9x, as described in: 7102 Peter Gutmann, Software Generation of Practically Strong 7103 Random Numbers. 7104 [Ulf M�ller] 7105 7106 *) Fix so PRNG is seeded in req if using an already existing 7107 DSA key. 7108 [Steve Henson] 7109 7110 *) New options to smime application. -inform and -outform 7111 allow alternative formats for the S/MIME message including 7112 PEM and DER. The -content option allows the content to be 7113 specified separately. This should allow things like Netscape 7114 form signing output easier to verify. 7115 [Steve Henson] 7116 7117 *) Fix the ASN1 encoding of tags using the 'long form'. 7118 [Steve Henson] 7119 7120 *) New ASN1 functions, i2c_* and c2i_* for INTEGER and BIT 7121 STRING types. These convert content octets to and from the 7122 underlying type. The actual tag and length octets are 7123 already assumed to have been read in and checked. These 7124 are needed because all other string types have virtually 7125 identical handling apart from the tag. By having versions 7126 of the ASN1 functions that just operate on content octets 7127 IMPLICIT tagging can be handled properly. It also allows 7128 the ASN1_ENUMERATED code to be cut down because ASN1_ENUMERATED 7129 and ASN1_INTEGER are identical apart from the tag. 7130 [Steve Henson] 7131 7132 *) Change the handling of OID objects as follows: 7133 7134 - New object identifiers are inserted in objects.txt, following 7135 the syntax given in objects.README. 7136 - objects.pl is used to process obj_mac.num and create a new 7137 obj_mac.h. 7138 - obj_dat.pl is used to create a new obj_dat.h, using the data in 7139 obj_mac.h. 7140 7141 This is currently kind of a hack, and the perl code in objects.pl 7142 isn't very elegant, but it works as I intended. The simplest way 7143 to check that it worked correctly is to look in obj_dat.h and 7144 check the array nid_objs and make sure the objects haven't moved 7145 around (this is important!). Additions are OK, as well as 7146 consistent name changes. 7147 [Richard Levitte] 7148 7149 *) Add BSD-style MD5-based passwords to 'openssl passwd' (option '-1'). 7150 [Bodo Moeller] 7151 7152 *) Addition of the command line parameter '-rand file' to 'openssl req'. 7153 The given file adds to whatever has already been seeded into the 7154 random pool through the RANDFILE configuration file option or 7155 environment variable, or the default random state file. 7156 [Richard Levitte] 7157 7158 *) mkstack.pl now sorts each macro group into lexical order. 7159 Previously the output order depended on the order the files 7160 appeared in the directory, resulting in needless rewriting 7161 of safestack.h . 7162 [Steve Henson] 7163 7164 *) Patches to make OpenSSL compile under Win32 again. Mostly 7165 work arounds for the VC++ problem that it treats func() as 7166 func(void). Also stripped out the parts of mkdef.pl that 7167 added extra typesafe functions: these no longer exist. 7168 [Steve Henson] 7169 7170 *) Reorganisation of the stack code. The macros are now all 7171 collected in safestack.h . Each macro is defined in terms of 7172 a "stack macro" of the form SKM_<name>(type, a, b). The 7173 DEBUG_SAFESTACK is now handled in terms of function casts, 7174 this has the advantage of retaining type safety without the 7175 use of additional functions. If DEBUG_SAFESTACK is not defined 7176 then the non typesafe macros are used instead. Also modified the 7177 mkstack.pl script to handle the new form. Needs testing to see 7178 if which (if any) compilers it chokes and maybe make DEBUG_SAFESTACK 7179 the default if no major problems. Similar behaviour for ASN1_SET_OF 7180 and PKCS12_STACK_OF. 7181 [Steve Henson] 7182 7183 *) When some versions of IIS use the 'NET' form of private key the 7184 key derivation algorithm is different. Normally MD5(password) is 7185 used as a 128 bit RC4 key. In the modified case 7186 MD5(MD5(password) + "SGCKEYSALT") is used insted. Added some 7187 new functions i2d_RSA_NET(), d2i_RSA_NET() etc which are the same 7188 as the old Netscape_RSA functions except they have an additional 7189 'sgckey' parameter which uses the modified algorithm. Also added 7190 an -sgckey command line option to the rsa utility. Thanks to 7191 Adrian Peck <bertie@ncipher.com> for posting details of the modified 7192 algorithm to openssl-dev. 7193 [Steve Henson] 7194 7195 *) The evp_local.h macros were using 'c.##kname' which resulted in 7196 invalid expansion on some systems (SCO 5.0.5 for example). 7197 Corrected to 'c.kname'. 7198 [Phillip Porch <root@theporch.com>] 7199 7200 *) New X509_get1_email() and X509_REQ_get1_email() functions that return 7201 a STACK of email addresses from a certificate or request, these look 7202 in the subject name and the subject alternative name extensions and 7203 omit any duplicate addresses. 7204 [Steve Henson] 7205 7206 *) Re-implement BN_mod_exp2_mont using independent (and larger) windows. 7207 This makes DSA verification about 2 % faster. 7208 [Bodo Moeller] 7209 7210 *) Increase maximum window size in BN_mod_exp_... to 6 bits instead of 5 7211 (meaning that now 2^5 values will be precomputed, which is only 4 KB 7212 plus overhead for 1024 bit moduli). 7213 This makes exponentiations about 0.5 % faster for 1024 bit 7214 exponents (as measured by "openssl speed rsa2048"). 7215 [Bodo Moeller] 7216 7217 *) Rename memory handling macros to avoid conflicts with other 7218 software: 7219 Malloc => OPENSSL_malloc 7220 Malloc_locked => OPENSSL_malloc_locked 7221 Realloc => OPENSSL_realloc 7222 Free => OPENSSL_free 7223 [Richard Levitte] 7224 7225 *) New function BN_mod_exp_mont_word for small bases (roughly 15% 7226 faster than BN_mod_exp_mont, i.e. 7% for a full DH exchange). 7227 [Bodo Moeller] 7228 7229 *) CygWin32 support. 7230 [John Jarvie <jjarvie@newsguy.com>] 7231 7232 *) The type-safe stack code has been rejigged. It is now only compiled 7233 in when OpenSSL is configured with the DEBUG_SAFESTACK option and 7234 by default all type-specific stack functions are "#define"d back to 7235 standard stack functions. This results in more streamlined output 7236 but retains the type-safety checking possibilities of the original 7237 approach. 7238 [Geoff Thorpe] 7239 7240 *) The STACK code has been cleaned up, and certain type declarations 7241 that didn't make a lot of sense have been brought in line. This has 7242 also involved a cleanup of sorts in safestack.h to more correctly 7243 map type-safe stack functions onto their plain stack counterparts. 7244 This work has also resulted in a variety of "const"ifications of 7245 lots of the code, especially "_cmp" operations which should normally 7246 be prototyped with "const" parameters anyway. 7247 [Geoff Thorpe] 7248 7249 *) When generating bytes for the first time in md_rand.c, 'stir the pool' 7250 by seeding with STATE_SIZE dummy bytes (with zero entropy count). 7251 (The PRNG state consists of two parts, the large pool 'state' and 'md', 7252 where all of 'md' is used each time the PRNG is used, but 'state' 7253 is used only indexed by a cyclic counter. As entropy may not be 7254 well distributed from the beginning, 'md' is important as a 7255 chaining variable. However, the output function chains only half 7256 of 'md', i.e. 80 bits. ssleay_rand_add, on the other hand, chains 7257 all of 'md', and seeding with STATE_SIZE dummy bytes will result 7258 in all of 'state' being rewritten, with the new values depending 7259 on virtually all of 'md'. This overcomes the 80 bit limitation.) 7260 [Bodo Moeller] 7261 7262 *) In ssl/s2_clnt.c and ssl/s3_clnt.c, call ERR_clear_error() when 7263 the handshake is continued after ssl_verify_cert_chain(); 7264 otherwise, if SSL_VERIFY_NONE is set, remaining error codes 7265 can lead to 'unexplainable' connection aborts later. 7266 [Bodo Moeller; problem tracked down by Lutz Jaenicke] 7267 7268 *) Major EVP API cipher revision. 7269 Add hooks for extra EVP features. This allows various cipher 7270 parameters to be set in the EVP interface. Support added for variable 7271 key length ciphers via the EVP_CIPHER_CTX_set_key_length() function and 7272 setting of RC2 and RC5 parameters. 7273 7274 Modify EVP_OpenInit() and EVP_SealInit() to cope with variable key length 7275 ciphers. 7276 7277 Remove lots of duplicated code from the EVP library. For example *every* 7278 cipher init() function handles the 'iv' in the same way according to the 7279 cipher mode. They also all do nothing if the 'key' parameter is NULL and 7280 for CFB and OFB modes they zero ctx->num. 7281 7282 New functionality allows removal of S/MIME code RC2 hack. 7283 7284 Most of the routines have the same form and so can be declared in terms 7285 of macros. 7286 7287 By shifting this to the top level EVP_CipherInit() it can be removed from 7288 all individual ciphers. If the cipher wants to handle IVs or keys 7289 differently it can set the EVP_CIPH_CUSTOM_IV or EVP_CIPH_ALWAYS_CALL_INIT 7290 flags. 7291 7292 Change lots of functions like EVP_EncryptUpdate() to now return a 7293 value: although software versions of the algorithms cannot fail 7294 any installed hardware versions can. 7295 [Steve Henson] 7296 7297 *) Implement SSL_OP_TLS_ROLLBACK_BUG: In ssl3_get_client_key_exchange, if 7298 this option is set, tolerate broken clients that send the negotiated 7299 protocol version number instead of the requested protocol version 7300 number. 7301 [Bodo Moeller] 7302 7303 *) Call dh_tmp_cb (set by ..._TMP_DH_CB) with correct 'is_export' flag; 7304 i.e. non-zero for export ciphersuites, zero otherwise. 7305 Previous versions had this flag inverted, inconsistent with 7306 rsa_tmp_cb (..._TMP_RSA_CB). 7307 [Bodo Moeller; problem reported by Amit Chopra] 7308 7309 *) Add missing DSA library text string. Work around for some IIS 7310 key files with invalid SEQUENCE encoding. 7311 [Steve Henson] 7312 7313 *) Add a document (doc/standards.txt) that list all kinds of standards 7314 and so on that are implemented in OpenSSL. 7315 [Richard Levitte] 7316 7317 *) Enhance c_rehash script. Old version would mishandle certificates 7318 with the same subject name hash and wouldn't handle CRLs at all. 7319 Added -fingerprint option to crl utility, to support new c_rehash 7320 features. 7321 [Steve Henson] 7322 7323 *) Eliminate non-ANSI declarations in crypto.h and stack.h. 7324 [Ulf M�ller] 7325 7326 *) Fix for SSL server purpose checking. Server checking was 7327 rejecting certificates which had extended key usage present 7328 but no ssl client purpose. 7329 [Steve Henson, reported by Rene Grosser <grosser@hisolutions.com>] 7330 7331 *) Make PKCS#12 code work with no password. The PKCS#12 spec 7332 is a little unclear about how a blank password is handled. 7333 Since the password in encoded as a BMPString with terminating 7334 double NULL a zero length password would end up as just the 7335 double NULL. However no password at all is different and is 7336 handled differently in the PKCS#12 key generation code. NS 7337 treats a blank password as zero length. MSIE treats it as no 7338 password on export: but it will try both on import. We now do 7339 the same: PKCS12_parse() tries zero length and no password if 7340 the password is set to "" or NULL (NULL is now a valid password: 7341 it wasn't before) as does the pkcs12 application. 7342 [Steve Henson] 7343 7344 *) Bugfixes in apps/x509.c: Avoid a memory leak; and don't use 7345 perror when PEM_read_bio_X509_REQ fails, the error message must 7346 be obtained from the error queue. 7347 [Bodo Moeller] 7348 7349 *) Avoid 'thread_hash' memory leak in crypto/err/err.c by freeing 7350 it in ERR_remove_state if appropriate, and change ERR_get_state 7351 accordingly to avoid race conditions (this is necessary because 7352 thread_hash is no longer constant once set). 7353 [Bodo Moeller] 7354 7355 *) Bugfix for linux-elf makefile.one. 7356 [Ulf M�ller] 7357 7358 *) RSA_get_default_method() will now cause a default 7359 RSA_METHOD to be chosen if one doesn't exist already. 7360 Previously this was only set during a call to RSA_new() 7361 or RSA_new_method(NULL) meaning it was possible for 7362 RSA_get_default_method() to return NULL. 7363 [Geoff Thorpe] 7364 7365 *) Added native name translation to the existing DSO code 7366 that will convert (if the flag to do so is set) filenames 7367 that are sufficiently small and have no path information 7368 into a canonical native form. Eg. "blah" converted to 7369 "libblah.so" or "blah.dll" etc. 7370 [Geoff Thorpe] 7371 7372 *) New function ERR_error_string_n(e, buf, len) which is like 7373 ERR_error_string(e, buf), but writes at most 'len' bytes 7374 including the 0 terminator. For ERR_error_string_n, 'buf' 7375 may not be NULL. 7376 [Damien Miller <djm@mindrot.org>, Bodo Moeller] 7377 7378 *) CONF library reworked to become more general. A new CONF 7379 configuration file reader "class" is implemented as well as a 7380 new functions (NCONF_*, for "New CONF") to handle it. The now 7381 old CONF_* functions are still there, but are reimplemented to 7382 work in terms of the new functions. Also, a set of functions 7383 to handle the internal storage of the configuration data is 7384 provided to make it easier to write new configuration file 7385 reader "classes" (I can definitely see something reading a 7386 configuration file in XML format, for example), called _CONF_*, 7387 or "the configuration storage API"... 7388 7389 The new configuration file reading functions are: 7390 7391 NCONF_new, NCONF_free, NCONF_load, NCONF_load_fp, NCONF_load_bio, 7392 NCONF_get_section, NCONF_get_string, NCONF_get_numbre 7393 7394 NCONF_default, NCONF_WIN32 7395 7396 NCONF_dump_fp, NCONF_dump_bio 7397 7398 NCONF_default and NCONF_WIN32 are method (or "class") choosers, 7399 NCONF_new creates a new CONF object. This works in the same way 7400 as other interfaces in OpenSSL, like the BIO interface. 7401 NCONF_dump_* dump the internal storage of the configuration file, 7402 which is useful for debugging. All other functions take the same 7403 arguments as the old CONF_* functions wth the exception of the 7404 first that must be a `CONF *' instead of a `LHASH *'. 7405 7406 To make it easer to use the new classes with the old CONF_* functions, 7407 the function CONF_set_default_method is provided. 7408 [Richard Levitte] 7409 7410 *) Add '-tls1' option to 'openssl ciphers', which was already 7411 mentioned in the documentation but had not been implemented. 7412 (This option is not yet really useful because even the additional 7413 experimental TLS 1.0 ciphers are currently treated as SSL 3.0 ciphers.) 7414 [Bodo Moeller] 7415 7416 *) Initial DSO code added into libcrypto for letting OpenSSL (and 7417 OpenSSL-based applications) load shared libraries and bind to 7418 them in a portable way. 7419 [Geoff Thorpe, with contributions from Richard Levitte] 7420 7421 Changes between 0.9.5 and 0.9.5a [1 Apr 2000] 7422 7423 *) Make sure _lrotl and _lrotr are only used with MSVC. 7424 7425 *) Use lock CRYPTO_LOCK_RAND correctly in ssleay_rand_status 7426 (the default implementation of RAND_status). 7427 7428 *) Rename openssl x509 option '-crlext', which was added in 0.9.5, 7429 to '-clrext' (= clear extensions), as intended and documented. 7430 [Bodo Moeller; inconsistency pointed out by Michael Attili 7431 <attili@amaxo.com>] 7432 7433 *) Fix for HMAC. It wasn't zeroing the rest of the block if the key length 7434 was larger than the MD block size. 7435 [Steve Henson, pointed out by Yost William <YostW@tce.com>] 7436 7437 *) Modernise PKCS12_parse() so it uses STACK_OF(X509) for its ca argument 7438 fix a leak when the ca argument was passed as NULL. Stop X509_PUBKEY_set() 7439 using the passed key: if the passed key was a private key the result 7440 of X509_print(), for example, would be to print out all the private key 7441 components. 7442 [Steve Henson] 7443 7444 *) des_quad_cksum() byte order bug fix. 7445 [Ulf M�ller, using the problem description in krb4-0.9.7, where 7446 the solution is attributed to Derrick J Brashear <shadow@DEMENTIA.ORG>] 7447 7448 *) Fix so V_ASN1_APP_CHOOSE works again: however its use is strongly 7449 discouraged. 7450 [Steve Henson, pointed out by Brian Korver <briank@cs.stanford.edu>] 7451 7452 *) For easily testing in shell scripts whether some command 7453 'openssl XXX' exists, the new pseudo-command 'openssl no-XXX' 7454 returns with exit code 0 iff no command of the given name is available. 7455 'no-XXX' is printed in this case, 'XXX' otherwise. In both cases, 7456 the output goes to stdout and nothing is printed to stderr. 7457 Additional arguments are always ignored. 7458 7459 Since for each cipher there is a command of the same name, 7460 the 'no-cipher' compilation switches can be tested this way. 7461 7462 ('openssl no-XXX' is not able to detect pseudo-commands such 7463 as 'quit', 'list-XXX-commands', or 'no-XXX' itself.) 7464 [Bodo Moeller] 7465 7466 *) Update test suite so that 'make test' succeeds in 'no-rsa' configuration. 7467 [Bodo Moeller] 7468 7469 *) For SSL_[CTX_]set_tmp_dh, don't create a DH key if SSL_OP_SINGLE_DH_USE 7470 is set; it will be thrown away anyway because each handshake creates 7471 its own key. 7472 ssl_cert_dup, which is used by SSL_new, now copies DH keys in addition 7473 to parameters -- in previous versions (since OpenSSL 0.9.3) the 7474 'default key' from SSL_CTX_set_tmp_dh would always be lost, meanining 7475 you effectivly got SSL_OP_SINGLE_DH_USE when using this macro. 7476 [Bodo Moeller] 7477 7478 *) New s_client option -ign_eof: EOF at stdin is ignored, and 7479 'Q' and 'R' lose their special meanings (quit/renegotiate). 7480 This is part of what -quiet does; unlike -quiet, -ign_eof 7481 does not suppress any output. 7482 [Richard Levitte] 7483 7484 *) Add compatibility options to the purpose and trust code. The 7485 purpose X509_PURPOSE_ANY is "any purpose" which automatically 7486 accepts a certificate or CA, this was the previous behaviour, 7487 with all the associated security issues. 7488 7489 X509_TRUST_COMPAT is the old trust behaviour: only and 7490 automatically trust self signed roots in certificate store. A 7491 new trust setting X509_TRUST_DEFAULT is used to specify that 7492 a purpose has no associated trust setting and it should instead 7493 use the value in the default purpose. 7494 [Steve Henson] 7495 7496 *) Fix the PKCS#8 DSA private key code so it decodes keys again 7497 and fix a memory leak. 7498 [Steve Henson] 7499 7500 *) In util/mkerr.pl (which implements 'make errors'), preserve 7501 reason strings from the previous version of the .c file, as 7502 the default to have only downcase letters (and digits) in 7503 automatically generated reasons codes is not always appropriate. 7504 [Bodo Moeller] 7505 7506 *) In ERR_load_ERR_strings(), build an ERR_LIB_SYS error reason table 7507 using strerror. Previously, ERR_reason_error_string() returned 7508 library names as reason strings for SYSerr; but SYSerr is a special 7509 case where small numbers are errno values, not library numbers. 7510 [Bodo Moeller] 7511 7512 *) Add '-dsaparam' option to 'openssl dhparam' application. This 7513 converts DSA parameters into DH parameters. (When creating parameters, 7514 DSA_generate_parameters is used.) 7515 [Bodo Moeller] 7516 7517 *) Include 'length' (recommended exponent length) in C code generated 7518 by 'openssl dhparam -C'. 7519 [Bodo Moeller] 7520 7521 *) The second argument to set_label in perlasm was already being used 7522 so couldn't be used as a "file scope" flag. Moved to third argument 7523 which was free. 7524 [Steve Henson] 7525 7526 *) In PEM_ASN1_write_bio and some other functions, use RAND_pseudo_bytes 7527 instead of RAND_bytes for encryption IVs and salts. 7528 [Bodo Moeller] 7529 7530 *) Include RAND_status() into RAND_METHOD instead of implementing 7531 it only for md_rand.c Otherwise replacing the PRNG by calling 7532 RAND_set_rand_method would be impossible. 7533 [Bodo Moeller] 7534 7535 *) Don't let DSA_generate_key() enter an infinite loop if the random 7536 number generation fails. 7537 [Bodo Moeller] 7538 7539 *) New 'rand' application for creating pseudo-random output. 7540 [Bodo Moeller] 7541 7542 *) Added configuration support for Linux/IA64 7543 [Rolf Haberrecker <rolf@suse.de>] 7544 7545 *) Assembler module support for Mingw32. 7546 [Ulf M�ller] 7547 7548 *) Shared library support for HPUX (in shlib/). 7549 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE> and Anonymous] 7550 7551 *) Shared library support for Solaris gcc. 7552 [Lutz Behnke <behnke@trustcenter.de>] 7553 7554 Changes between 0.9.4 and 0.9.5 [28 Feb 2000] 7555 7556 *) PKCS7_encrypt() was adding text MIME headers twice because they 7557 were added manually and by SMIME_crlf_copy(). 7558 [Steve Henson] 7559 7560 *) In bntest.c don't call BN_rand with zero bits argument. 7561 [Steve Henson, pointed out by Andrew W. Gray <agray@iconsinc.com>] 7562 7563 *) BN_mul bugfix: In bn_mul_part_recursion() only the a>a[n] && b>b[n] 7564 case was implemented. This caused BN_div_recp() to fail occasionally. 7565 [Ulf M�ller] 7566 7567 *) Add an optional second argument to the set_label() in the perl 7568 assembly language builder. If this argument exists and is set 7569 to 1 it signals that the assembler should use a symbol whose 7570 scope is the entire file, not just the current function. This 7571 is needed with MASM which uses the format label:: for this scope. 7572 [Steve Henson, pointed out by Peter Runestig <peter@runestig.com>] 7573 7574 *) Change the ASN1 types so they are typedefs by default. Before 7575 almost all types were #define'd to ASN1_STRING which was causing 7576 STACK_OF() problems: you couldn't declare STACK_OF(ASN1_UTF8STRING) 7577 for example. 7578 [Steve Henson] 7579 7580 *) Change names of new functions to the new get1/get0 naming 7581 convention: After 'get1', the caller owns a reference count 7582 and has to call ..._free; 'get0' returns a pointer to some 7583 data structure without incrementing reference counters. 7584 (Some of the existing 'get' functions increment a reference 7585 counter, some don't.) 7586 Similarly, 'set1' and 'add1' functions increase reference 7587 counters or duplicate objects. 7588 [Steve Henson] 7589 7590 *) Allow for the possibility of temp RSA key generation failure: 7591 the code used to assume it always worked and crashed on failure. 7592 [Steve Henson] 7593 7594 *) Fix potential buffer overrun problem in BIO_printf(). 7595 [Ulf M�ller, using public domain code by Patrick Powell; problem 7596 pointed out by David Sacerdote <das33@cornell.edu>] 7597 7598 *) Support EGD <http://www.lothar.com/tech/crypto/>. New functions 7599 RAND_egd() and RAND_status(). In the command line application, 7600 the EGD socket can be specified like a seed file using RANDFILE 7601 or -rand. 7602 [Ulf M�ller] 7603 7604 *) Allow the string CERTIFICATE to be tolerated in PKCS#7 structures. 7605 Some CAs (e.g. Verisign) distribute certificates in this form. 7606 [Steve Henson] 7607 7608 *) Remove the SSL_ALLOW_ADH compile option and set the default cipher 7609 list to exclude them. This means that no special compilation option 7610 is needed to use anonymous DH: it just needs to be included in the 7611 cipher list. 7612 [Steve Henson] 7613 7614 *) Change the EVP_MD_CTX_type macro so its meaning consistent with 7615 EVP_MD_type. The old functionality is available in a new macro called 7616 EVP_MD_md(). Change code that uses it and update docs. 7617 [Steve Henson] 7618 7619 *) ..._ctrl functions now have corresponding ..._callback_ctrl functions 7620 where the 'void *' argument is replaced by a function pointer argument. 7621 Previously 'void *' was abused to point to functions, which works on 7622 many platforms, but is not correct. As these functions are usually 7623 called by macros defined in OpenSSL header files, most source code 7624 should work without changes. 7625 [Richard Levitte] 7626 7627 *) <openssl/opensslconf.h> (which is created by Configure) now contains 7628 sections with information on -D... compiler switches used for 7629 compiling the library so that applications can see them. To enable 7630 one of these sections, a pre-processor symbol OPENSSL_..._DEFINES 7631 must be defined. E.g., 7632 #define OPENSSL_ALGORITHM_DEFINES 7633 #include <openssl/opensslconf.h> 7634 defines all pertinent NO_<algo> symbols, such as NO_IDEA, NO_RSA, etc. 7635 [Richard Levitte, Ulf and Bodo M�ller] 7636 7637 *) Bugfix: Tolerate fragmentation and interleaving in the SSL 3/TLS 7638 record layer. 7639 [Bodo Moeller] 7640 7641 *) Change the 'other' type in certificate aux info to a STACK_OF 7642 X509_ALGOR. Although not an AlgorithmIdentifier as such it has 7643 the required ASN1 format: arbitrary types determined by an OID. 7644 [Steve Henson] 7645 7646 *) Add some PEM_write_X509_REQ_NEW() functions and a command line 7647 argument to 'req'. This is not because the function is newer or 7648 better than others it just uses the work 'NEW' in the certificate 7649 request header lines. Some software needs this. 7650 [Steve Henson] 7651 7652 *) Reorganise password command line arguments: now passwords can be 7653 obtained from various sources. Delete the PEM_cb function and make 7654 it the default behaviour: i.e. if the callback is NULL and the 7655 usrdata argument is not NULL interpret it as a null terminated pass 7656 phrase. If usrdata and the callback are NULL then the pass phrase 7657 is prompted for as usual. 7658 [Steve Henson] 7659 7660 *) Add support for the Compaq Atalla crypto accelerator. If it is installed, 7661 the support is automatically enabled. The resulting binaries will 7662 autodetect the card and use it if present. 7663 [Ben Laurie and Compaq Inc.] 7664 7665 *) Work around for Netscape hang bug. This sends certificate request 7666 and server done in one record. Since this is perfectly legal in the 7667 SSL/TLS protocol it isn't a "bug" option and is on by default. See 7668 the bugs/SSLv3 entry for more info. 7669 [Steve Henson] 7670 7671 *) HP-UX tune-up: new unified configs, HP C compiler bug workaround. 7672 [Andy Polyakov] 7673 7674 *) Add -rand argument to smime and pkcs12 applications and read/write 7675 of seed file. 7676 [Steve Henson] 7677 7678 *) New 'passwd' tool for crypt(3) and apr1 password hashes. 7679 [Bodo Moeller] 7680 7681 *) Add command line password options to the remaining applications. 7682 [Steve Henson] 7683 7684 *) Bug fix for BN_div_recp() for numerators with an even number of 7685 bits. 7686 [Ulf M�ller] 7687 7688 *) More tests in bntest.c, and changed test_bn output. 7689 [Ulf M�ller] 7690 7691 *) ./config recognizes MacOS X now. 7692 [Andy Polyakov] 7693 7694 *) Bug fix for BN_div() when the first words of num and divsor are 7695 equal (it gave wrong results if (rem=(n1-q*d0)&BN_MASK2) < d0). 7696 [Ulf M�ller] 7697 7698 *) Add support for various broken PKCS#8 formats, and command line 7699 options to produce them. 7700 [Steve Henson] 7701 7702 *) New functions BN_CTX_start(), BN_CTX_get() and BT_CTX_end() to 7703 get temporary BIGNUMs from a BN_CTX. 7704 [Ulf M�ller] 7705 7706 *) Correct return values in BN_mod_exp_mont() and BN_mod_exp2_mont() 7707 for p == 0. 7708 [Ulf M�ller] 7709 7710 *) Change the SSLeay_add_all_*() functions to OpenSSL_add_all_*() and 7711 include a #define from the old name to the new. The original intent 7712 was that statically linked binaries could for example just call 7713 SSLeay_add_all_ciphers() to just add ciphers to the table and not 7714 link with digests. This never worked becayse SSLeay_add_all_digests() 7715 and SSLeay_add_all_ciphers() were in the same source file so calling 7716 one would link with the other. They are now in separate source files. 7717 [Steve Henson] 7718 7719 *) Add a new -notext option to 'ca' and a -pubkey option to 'spkac'. 7720 [Steve Henson] 7721 7722 *) Use a less unusual form of the Miller-Rabin primality test (it used 7723 a binary algorithm for exponentiation integrated into the Miller-Rabin 7724 loop, our standard modexp algorithms are faster). 7725 [Bodo Moeller] 7726 7727 *) Support for the EBCDIC character set completed. 7728 [Martin Kraemer <Martin.Kraemer@Mch.SNI.De>] 7729 7730 *) Source code cleanups: use const where appropriate, eliminate casts, 7731 use void * instead of char * in lhash. 7732 [Ulf M�ller] 7733 7734 *) Bugfix: ssl3_send_server_key_exchange was not restartable 7735 (the state was not changed to SSL3_ST_SW_KEY_EXCH_B, and because of 7736 this the server could overwrite ephemeral keys that the client 7737 has already seen). 7738 [Bodo Moeller] 7739 7740 *) Turn DSA_is_prime into a macro that calls BN_is_prime, 7741 using 50 iterations of the Rabin-Miller test. 7742 7743 DSA_generate_parameters now uses BN_is_prime_fasttest (with 50 7744 iterations of the Rabin-Miller test as required by the appendix 7745 to FIPS PUB 186[-1]) instead of DSA_is_prime. 7746 As BN_is_prime_fasttest includes trial division, DSA parameter 7747 generation becomes much faster. 7748 7749 This implies a change for the callback functions in DSA_is_prime 7750 and DSA_generate_parameters: The callback function is called once 7751 for each positive witness in the Rabin-Miller test, not just 7752 occasionally in the inner loop; and the parameters to the 7753 callback function now provide an iteration count for the outer 7754 loop rather than for the current invocation of the inner loop. 7755 DSA_generate_parameters additionally can call the callback 7756 function with an 'iteration count' of -1, meaning that a 7757 candidate has passed the trial division test (when q is generated 7758 from an application-provided seed, trial division is skipped). 7759 [Bodo Moeller] 7760 7761 *) New function BN_is_prime_fasttest that optionally does trial 7762 division before starting the Rabin-Miller test and has 7763 an additional BN_CTX * argument (whereas BN_is_prime always 7764 has to allocate at least one BN_CTX). 7765 'callback(1, -1, cb_arg)' is called when a number has passed the 7766 trial division stage. 7767 [Bodo Moeller] 7768 7769 *) Fix for bug in CRL encoding. The validity dates weren't being handled 7770 as ASN1_TIME. 7771 [Steve Henson] 7772 7773 *) New -pkcs12 option to CA.pl script to write out a PKCS#12 file. 7774 [Steve Henson] 7775 7776 *) New function BN_pseudo_rand(). 7777 [Ulf M�ller] 7778 7779 *) Clean up BN_mod_mul_montgomery(): replace the broken (and unreadable) 7780 bignum version of BN_from_montgomery() with the working code from 7781 SSLeay 0.9.0 (the word based version is faster anyway), and clean up 7782 the comments. 7783 [Ulf M�ller] 7784 7785 *) Avoid a race condition in s2_clnt.c (function get_server_hello) that 7786 made it impossible to use the same SSL_SESSION data structure in 7787 SSL2 clients in multiple threads. 7788 [Bodo Moeller] 7789 7790 *) The return value of RAND_load_file() no longer counts bytes obtained 7791 by stat(). RAND_load_file(..., -1) is new and uses the complete file 7792 to seed the PRNG (previously an explicit byte count was required). 7793 [Ulf M�ller, Bodo M�ller] 7794 7795 *) Clean up CRYPTO_EX_DATA functions, some of these didn't have prototypes 7796 used (char *) instead of (void *) and had casts all over the place. 7797 [Steve Henson] 7798 7799 *) Make BN_generate_prime() return NULL on error if ret!=NULL. 7800 [Ulf M�ller] 7801 7802 *) Retain source code compatibility for BN_prime_checks macro: 7803 BN_is_prime(..., BN_prime_checks, ...) now uses 7804 BN_prime_checks_for_size to determine the appropriate number of 7805 Rabin-Miller iterations. 7806 [Ulf M�ller] 7807 7808 *) Diffie-Hellman uses "safe" primes: DH_check() return code renamed to 7809 DH_CHECK_P_NOT_SAFE_PRIME. 7810 (Check if this is true? OpenPGP calls them "strong".) 7811 [Ulf M�ller] 7812 7813 *) Merge the functionality of "dh" and "gendh" programs into a new program 7814 "dhparam". The old programs are retained for now but will handle DH keys 7815 (instead of parameters) in future. 7816 [Steve Henson] 7817 7818 *) Make the ciphers, s_server and s_client programs check the return values 7819 when a new cipher list is set. 7820 [Steve Henson] 7821 7822 *) Enhance the SSL/TLS cipher mechanism to correctly handle the TLS 56bit 7823 ciphers. Before when the 56bit ciphers were enabled the sorting was 7824 wrong. 7825 7826 The syntax for the cipher sorting has been extended to support sorting by 7827 cipher-strength (using the strength_bits hard coded in the tables). 7828 The new command is "@STRENGTH" (see also doc/apps/ciphers.pod). 7829 7830 Fix a bug in the cipher-command parser: when supplying a cipher command 7831 string with an "undefined" symbol (neither command nor alphanumeric 7832 [A-Za-z0-9], ssl_set_cipher_list used to hang in an endless loop. Now 7833 an error is flagged. 7834 7835 Due to the strength-sorting extension, the code of the 7836 ssl_create_cipher_list() function was completely rearranged. I hope that 7837 the readability was also increased :-) 7838 [Lutz Jaenicke <Lutz.Jaenicke@aet.TU-Cottbus.DE>] 7839 7840 *) Minor change to 'x509' utility. The -CAcreateserial option now uses 1 7841 for the first serial number and places 2 in the serial number file. This 7842 avoids problems when the root CA is created with serial number zero and 7843 the first user certificate has the same issuer name and serial number 7844 as the root CA. 7845 [Steve Henson] 7846 7847 *) Fixes to X509_ATTRIBUTE utilities, change the 'req' program so it uses 7848 the new code. Add documentation for this stuff. 7849 [Steve Henson] 7850 7851 *) Changes to X509_ATTRIBUTE utilities. These have been renamed from 7852 X509_*() to X509at_*() on the grounds that they don't handle X509 7853 structures and behave in an analagous way to the X509v3 functions: 7854 they shouldn't be called directly but wrapper functions should be used 7855 instead. 7856 7857 So we also now have some wrapper functions that call the X509at functions 7858 when passed certificate requests. (TO DO: similar things can be done with 7859 PKCS#7 signed and unsigned attributes, PKCS#12 attributes and a few other 7860 things. Some of these need some d2i or i2d and print functionality 7861 because they handle more complex structures.) 7862 [Steve Henson] 7863 7864 *) Add missing #ifndefs that caused missing symbols when building libssl 7865 as a shared library without RSA. Use #ifndef NO_SSL2 instead of 7866 NO_RSA in ssl/s2*.c. 7867 [Kris Kennaway <kris@hub.freebsd.org>, modified by Ulf M�ller] 7868 7869 *) Precautions against using the PRNG uninitialized: RAND_bytes() now 7870 has a return value which indicates the quality of the random data 7871 (1 = ok, 0 = not seeded). Also an error is recorded on the thread's 7872 error queue. New function RAND_pseudo_bytes() generates output that is 7873 guaranteed to be unique but not unpredictable. RAND_add is like 7874 RAND_seed, but takes an extra argument for an entropy estimate 7875 (RAND_seed always assumes full entropy). 7876 [Ulf M�ller] 7877 7878 *) Do more iterations of Rabin-Miller probable prime test (specifically, 7879 3 for 1024-bit primes, 6 for 512-bit primes, 12 for 256-bit primes 7880 instead of only 2 for all lengths; see BN_prime_checks_for_size definition 7881 in crypto/bn/bn_prime.c for the complete table). This guarantees a 7882 false-positive rate of at most 2^-80 for random input. 7883 [Bodo Moeller] 7884 7885 *) Rewrite ssl3_read_n (ssl/s3_pkt.c) avoiding a couple of bugs. 7886 [Bodo Moeller] 7887 7888 *) New function X509_CTX_rget_chain() (renamed to X509_CTX_get1_chain 7889 in the 0.9.5 release), this returns the chain 7890 from an X509_CTX structure with a dup of the stack and all 7891 the X509 reference counts upped: so the stack will exist 7892 after X509_CTX_cleanup() has been called. Modify pkcs12.c 7893 to use this. 7894 7895 Also make SSL_SESSION_print() print out the verify return 7896 code. 7897 [Steve Henson] 7898 7899 *) Add manpage for the pkcs12 command. Also change the default 7900 behaviour so MAC iteration counts are used unless the new 7901 -nomaciter option is used. This improves file security and 7902 only older versions of MSIE (4.0 for example) need it. 7903 [Steve Henson] 7904 7905 *) Honor the no-xxx Configure options when creating .DEF files. 7906 [Ulf M�ller] 7907 7908 *) Add PKCS#10 attributes to field table: challengePassword, 7909 unstructuredName and unstructuredAddress. These are taken from 7910 draft PKCS#9 v2.0 but are compatible with v1.2 provided no 7911 international characters are used. 7912 7913 More changes to X509_ATTRIBUTE code: allow the setting of types 7914 based on strings. Remove the 'loc' parameter when adding 7915 attributes because these will be a SET OF encoding which is sorted 7916 in ASN1 order. 7917 [Steve Henson] 7918 7919 *) Initial changes to the 'req' utility to allow request generation 7920 automation. This will allow an application to just generate a template 7921 file containing all the field values and have req construct the 7922 request. 7923 7924 Initial support for X509_ATTRIBUTE handling. Stacks of these are 7925 used all over the place including certificate requests and PKCS#7 7926 structures. They are currently handled manually where necessary with 7927 some primitive wrappers for PKCS#7. The new functions behave in a 7928 manner analogous to the X509 extension functions: they allow 7929 attributes to be looked up by NID and added. 7930 7931 Later something similar to the X509V3 code would be desirable to 7932 automatically handle the encoding, decoding and printing of the 7933 more complex types. The string types like challengePassword can 7934 be handled by the string table functions. 7935 7936 Also modified the multi byte string table handling. Now there is 7937 a 'global mask' which masks out certain types. The table itself 7938 can use the flag STABLE_NO_MASK to ignore the mask setting: this 7939 is useful when for example there is only one permissible type 7940 (as in countryName) and using the mask might result in no valid 7941 types at all. 7942 [Steve Henson] 7943 7944 *) Clean up 'Finished' handling, and add functions SSL_get_finished and 7945 SSL_get_peer_finished to allow applications to obtain the latest 7946 Finished messages sent to the peer or expected from the peer, 7947 respectively. (SSL_get_peer_finished is usually the Finished message 7948 actually received from the peer, otherwise the protocol will be aborted.) 7949 7950 As the Finished message are message digests of the complete handshake 7951 (with a total of 192 bits for TLS 1.0 and more for SSL 3.0), they can 7952 be used for external authentication procedures when the authentication 7953 provided by SSL/TLS is not desired or is not enough. 7954 [Bodo Moeller] 7955 7956 *) Enhanced support for Alpha Linux is added. Now ./config checks if 7957 the host supports BWX extension and if Compaq C is present on the 7958 $PATH. Just exploiting of the BWX extension results in 20-30% 7959 performance kick for some algorithms, e.g. DES and RC4 to mention 7960 a couple. Compaq C in turn generates ~20% faster code for MD5 and 7961 SHA1. 7962 [Andy Polyakov] 7963 7964 *) Add support for MS "fast SGC". This is arguably a violation of the 7965 SSL3/TLS protocol. Netscape SGC does two handshakes: the first with 7966 weak crypto and after checking the certificate is SGC a second one 7967 with strong crypto. MS SGC stops the first handshake after receiving 7968 the server certificate message and sends a second client hello. Since 7969 a server will typically do all the time consuming operations before 7970 expecting any further messages from the client (server key exchange 7971 is the most expensive) there is little difference between the two. 7972 7973 To get OpenSSL to support MS SGC we have to permit a second client 7974 hello message after we have sent server done. In addition we have to 7975 reset the MAC if we do get this second client hello. 7976 [Steve Henson] 7977 7978 *) Add a function 'd2i_AutoPrivateKey()' this will automatically decide 7979 if a DER encoded private key is RSA or DSA traditional format. Changed 7980 d2i_PrivateKey_bio() to use it. This is only needed for the "traditional" 7981 format DER encoded private key. Newer code should use PKCS#8 format which 7982 has the key type encoded in the ASN1 structure. Added DER private key 7983 support to pkcs8 application. 7984 [Steve Henson] 7985 7986 *) SSL 3/TLS 1 servers now don't request certificates when an anonymous 7987 ciphersuites has been selected (as required by the SSL 3/TLS 1 7988 specifications). Exception: When SSL_VERIFY_FAIL_IF_NO_PEER_CERT 7989 is set, we interpret this as a request to violate the specification 7990 (the worst that can happen is a handshake failure, and 'correct' 7991 behaviour would result in a handshake failure anyway). 7992 [Bodo Moeller] 7993 7994 *) In SSL_CTX_add_session, take into account that there might be multiple 7995 SSL_SESSION structures with the same session ID (e.g. when two threads 7996 concurrently obtain them from an external cache). 7997 The internal cache can handle only one SSL_SESSION with a given ID, 7998 so if there's a conflict, we now throw out the old one to achieve 7999 consistency. 8000 [Bodo Moeller] 8001 8002 *) Add OIDs for idea and blowfish in CBC mode. This will allow both 8003 to be used in PKCS#5 v2.0 and S/MIME. Also add checking to 8004 some routines that use cipher OIDs: some ciphers do not have OIDs 8005 defined and so they cannot be used for S/MIME and PKCS#5 v2.0 for 8006 example. 8007 [Steve Henson] 8008 8009 *) Simplify the trust setting structure and code. Now we just have 8010 two sequences of OIDs for trusted and rejected settings. These will 8011 typically have values the same as the extended key usage extension 8012 and any application specific purposes. 8013 8014 The trust checking code now has a default behaviour: it will just 8015 check for an object with the same NID as the passed id. Functions can 8016 be provided to override either the default behaviour or the behaviour 8017 for a given id. SSL client, server and email already have functions 8018 in place for compatibility: they check the NID and also return "trusted" 8019 if the certificate is self signed. 8020 [Steve Henson] 8021 8022 *) Add d2i,i2d bio/fp functions for PrivateKey: these convert the 8023 traditional format into an EVP_PKEY structure. 8024 [Steve Henson] 8025 8026 *) Add a password callback function PEM_cb() which either prompts for 8027 a password if usr_data is NULL or otherwise assumes it is a null 8028 terminated password. Allow passwords to be passed on command line 8029 environment or config files in a few more utilities. 8030 [Steve Henson] 8031 8032 *) Add a bunch of DER and PEM functions to handle PKCS#8 format private 8033 keys. Add some short names for PKCS#8 PBE algorithms and allow them 8034 to be specified on the command line for the pkcs8 and pkcs12 utilities. 8035 Update documentation. 8036 [Steve Henson] 8037 8038 *) Support for ASN1 "NULL" type. This could be handled before by using 8039 ASN1_TYPE but there wasn't any function that would try to read a NULL 8040 and produce an error if it couldn't. For compatibility we also have 8041 ASN1_NULL_new() and ASN1_NULL_free() functions but these are faked and 8042 don't allocate anything because they don't need to. 8043 [Steve Henson] 8044 8045 *) Initial support for MacOS is now provided. Examine INSTALL.MacOS 8046 for details. 8047 [Andy Polyakov, Roy Woods <roy@centicsystems.ca>] 8048 8049 *) Rebuild of the memory allocation routines used by OpenSSL code and 8050 possibly others as well. The purpose is to make an interface that 8051 provide hooks so anyone can build a separate set of allocation and 8052 deallocation routines to be used by OpenSSL, for example memory 8053 pool implementations, or something else, which was previously hard 8054 since Malloc(), Realloc() and Free() were defined as macros having 8055 the values malloc, realloc and free, respectively (except for Win32 8056 compilations). The same is provided for memory debugging code. 8057 OpenSSL already comes with functionality to find memory leaks, but 8058 this gives people a chance to debug other memory problems. 8059 8060 With these changes, a new set of functions and macros have appeared: 8061 8062 CRYPTO_set_mem_debug_functions() [F] 8063 CRYPTO_get_mem_debug_functions() [F] 8064 CRYPTO_dbg_set_options() [F] 8065 CRYPTO_dbg_get_options() [F] 8066 CRYPTO_malloc_debug_init() [M] 8067 8068 The memory debug functions are NULL by default, unless the library 8069 is compiled with CRYPTO_MDEBUG or friends is defined. If someone 8070 wants to debug memory anyway, CRYPTO_malloc_debug_init() (which 8071 gives the standard debugging functions that come with OpenSSL) or 8072 CRYPTO_set_mem_debug_functions() (tells OpenSSL to use functions 8073 provided by the library user) must be used. When the standard 8074 debugging functions are used, CRYPTO_dbg_set_options can be used to 8075 request additional information: 8076 CRYPTO_dbg_set_options(V_CYRPTO_MDEBUG_xxx) corresponds to setting 8077 the CRYPTO_MDEBUG_xxx macro when compiling the library. 8078 8079 Also, things like CRYPTO_set_mem_functions will always give the 8080 expected result (the new set of functions is used for allocation 8081 and deallocation) at all times, regardless of platform and compiler 8082 options. 8083 8084 To finish it up, some functions that were never use in any other 8085 way than through macros have a new API and new semantic: 8086 8087 CRYPTO_dbg_malloc() 8088 CRYPTO_dbg_realloc() 8089 CRYPTO_dbg_free() 8090 8091 All macros of value have retained their old syntax. 8092 [Richard Levitte and Bodo Moeller] 8093 8094 *) Some S/MIME fixes. The OID for SMIMECapabilities was wrong, the 8095 ordering of SMIMECapabilities wasn't in "strength order" and there 8096 was a missing NULL in the AlgorithmIdentifier for the SHA1 signature 8097 algorithm. 8098 [Steve Henson] 8099 8100 *) Some ASN1 types with illegal zero length encoding (INTEGER, 8101 ENUMERATED and OBJECT IDENTIFIER) choked the ASN1 routines. 8102 [Frans Heymans <fheymans@isaserver.be>, modified by Steve Henson] 8103 8104 *) Merge in my S/MIME library for OpenSSL. This provides a simple 8105 S/MIME API on top of the PKCS#7 code, a MIME parser (with enough 8106 functionality to handle multipart/signed properly) and a utility 8107 called 'smime' to call all this stuff. This is based on code I 8108 originally wrote for Celo who have kindly allowed it to be 8109 included in OpenSSL. 8110 [Steve Henson] 8111 8112 *) Add variants des_set_key_checked and des_set_key_unchecked of 8113 des_set_key (aka des_key_sched). Global variable des_check_key 8114 decides which of these is called by des_set_key; this way 8115 des_check_key behaves as it always did, but applications and 8116 the library itself, which was buggy for des_check_key == 1, 8117 have a cleaner way to pick the version they need. 8118 [Bodo Moeller] 8119 8120 *) New function PKCS12_newpass() which changes the password of a 8121 PKCS12 structure. 8122 [Steve Henson] 8123 8124 *) Modify X509_TRUST and X509_PURPOSE so it also uses a static and 8125 dynamic mix. In both cases the ids can be used as an index into the 8126 table. Also modified the X509_TRUST_add() and X509_PURPOSE_add() 8127 functions so they accept a list of the field values and the 8128 application doesn't need to directly manipulate the X509_TRUST 8129 structure. 8130 [Steve Henson] 8131 8132 *) Modify the ASN1_STRING_TABLE stuff so it also uses bsearch and doesn't 8133 need initialising. 8134 [Steve Henson] 8135 8136 *) Modify the way the V3 extension code looks up extensions. This now 8137 works in a similar way to the object code: we have some "standard" 8138 extensions in a static table which is searched with OBJ_bsearch() 8139 and the application can add dynamic ones if needed. The file 8140 crypto/x509v3/ext_dat.h now has the info: this file needs to be 8141 updated whenever a new extension is added to the core code and kept 8142 in ext_nid order. There is a simple program 'tabtest.c' which checks 8143 this. New extensions are not added too often so this file can readily 8144 be maintained manually. 8145 8146 There are two big advantages in doing things this way. The extensions 8147 can be looked up immediately and no longer need to be "added" using 8148 X509V3_add_standard_extensions(): this function now does nothing. 8149 [Side note: I get *lots* of email saying the extension code doesn't 8150 work because people forget to call this function] 8151 Also no dynamic allocation is done unless new extensions are added: 8152 so if we don't add custom extensions there is no need to call 8153 X509V3_EXT_cleanup(). 8154 [Steve Henson] 8155 8156 *) Modify enc utility's salting as follows: make salting the default. Add a 8157 magic header, so unsalted files fail gracefully instead of just decrypting 8158 to garbage. This is because not salting is a big security hole, so people 8159 should be discouraged from doing it. 8160 [Ben Laurie] 8161 8162 *) Fixes and enhancements to the 'x509' utility. It allowed a message 8163 digest to be passed on the command line but it only used this 8164 parameter when signing a certificate. Modified so all relevant 8165 operations are affected by the digest parameter including the 8166 -fingerprint and -x509toreq options. Also -x509toreq choked if a 8167 DSA key was used because it didn't fix the digest. 8168 [Steve Henson] 8169 8170 *) Initial certificate chain verify code. Currently tests the untrusted 8171 certificates for consistency with the verify purpose (which is set 8172 when the X509_STORE_CTX structure is set up) and checks the pathlength. 8173 8174 There is a NO_CHAIN_VERIFY compilation option to keep the old behaviour: 8175 this is because it will reject chains with invalid extensions whereas 8176 every previous version of OpenSSL and SSLeay made no checks at all. 8177 8178 Trust code: checks the root CA for the relevant trust settings. Trust 8179 settings have an initial value consistent with the verify purpose: e.g. 8180 if the verify purpose is for SSL client use it expects the CA to be 8181 trusted for SSL client use. However the default value can be changed to 8182 permit custom trust settings: one example of this would be to only trust 8183 certificates from a specific "secure" set of CAs. 8184 8185 Also added X509_STORE_CTX_new() and X509_STORE_CTX_free() functions 8186 which should be used for version portability: especially since the 8187 verify structure is likely to change more often now. 8188 8189 SSL integration. Add purpose and trust to SSL_CTX and SSL and functions 8190 to set them. If not set then assume SSL clients will verify SSL servers 8191 and vice versa. 8192 8193 Two new options to the verify program: -untrusted allows a set of 8194 untrusted certificates to be passed in and -purpose which sets the 8195 intended purpose of the certificate. If a purpose is set then the 8196 new chain verify code is used to check extension consistency. 8197 [Steve Henson] 8198 8199 *) Support for the authority information access extension. 8200 [Steve Henson] 8201 8202 *) Modify RSA and DSA PEM read routines to transparently handle 8203 PKCS#8 format private keys. New *_PUBKEY_* functions that handle 8204 public keys in a format compatible with certificate 8205 SubjectPublicKeyInfo structures. Unfortunately there were already 8206 functions called *_PublicKey_* which used various odd formats so 8207 these are retained for compatibility: however the DSA variants were 8208 never in a public release so they have been deleted. Changed dsa/rsa 8209 utilities to handle the new format: note no releases ever handled public 8210 keys so we should be OK. 8211 8212 The primary motivation for this change is to avoid the same fiasco 8213 that dogs private keys: there are several incompatible private key 8214 formats some of which are standard and some OpenSSL specific and 8215 require various evil hacks to allow partial transparent handling and 8216 even then it doesn't work with DER formats. Given the option anything 8217 other than PKCS#8 should be dumped: but the other formats have to 8218 stay in the name of compatibility. 8219 8220 With public keys and the benefit of hindsight one standard format 8221 is used which works with EVP_PKEY, RSA or DSA structures: though 8222 it clearly returns an error if you try to read the wrong kind of key. 8223 8224 Added a -pubkey option to the 'x509' utility to output the public key. 8225 Also rename the EVP_PKEY_get_*() to EVP_PKEY_rget_*() 8226 (renamed to EVP_PKEY_get1_*() in the OpenSSL 0.9.5 release) and add 8227 EVP_PKEY_rset_*() functions (renamed to EVP_PKEY_set1_*()) 8228 that do the same as the EVP_PKEY_assign_*() except they up the 8229 reference count of the added key (they don't "swallow" the 8230 supplied key). 8231 [Steve Henson] 8232 8233 *) Fixes to crypto/x509/by_file.c the code to read in certificates and 8234 CRLs would fail if the file contained no certificates or no CRLs: 8235 added a new function to read in both types and return the number 8236 read: this means that if none are read it will be an error. The 8237 DER versions of the certificate and CRL reader would always fail 8238 because it isn't possible to mix certificates and CRLs in DER format 8239 without choking one or the other routine. Changed this to just read 8240 a certificate: this is the best we can do. Also modified the code 8241 in apps/verify.c to take notice of return codes: it was previously 8242 attempting to read in certificates from NULL pointers and ignoring 8243 any errors: this is one reason why the cert and CRL reader seemed 8244 to work. It doesn't check return codes from the default certificate 8245 routines: these may well fail if the certificates aren't installed. 8246 [Steve Henson] 8247 8248 *) Code to support otherName option in GeneralName. 8249 [Steve Henson] 8250 8251 *) First update to verify code. Change the verify utility 8252 so it warns if it is passed a self signed certificate: 8253 for consistency with the normal behaviour. X509_verify 8254 has been modified to it will now verify a self signed 8255 certificate if *exactly* the same certificate appears 8256 in the store: it was previously impossible to trust a 8257 single self signed certificate. This means that: 8258 openssl verify ss.pem 8259 now gives a warning about a self signed certificate but 8260 openssl verify -CAfile ss.pem ss.pem 8261 is OK. 8262 [Steve Henson] 8263 8264 *) For servers, store verify_result in SSL_SESSION data structure 8265 (and add it to external session representation). 8266 This is needed when client certificate verifications fails, 8267 but an application-provided verification callback (set by 8268 SSL_CTX_set_cert_verify_callback) allows accepting the session 8269 anyway (i.e. leaves x509_store_ctx->error != X509_V_OK 8270 but returns 1): When the session is reused, we have to set 8271 ssl->verify_result to the appropriate error code to avoid 8272 security holes. 8273 [Bodo Moeller, problem pointed out by Lutz Jaenicke] 8274 8275 *) Fix a bug in the new PKCS#7 code: it didn't consider the 8276 case in PKCS7_dataInit() where the signed PKCS7 structure 8277 didn't contain any existing data because it was being created. 8278 [Po-Cheng Chen <pocheng@nst.com.tw>, slightly modified by Steve Henson] 8279 8280 *) Add a salt to the key derivation routines in enc.c. This 8281 forms the first 8 bytes of the encrypted file. Also add a 8282 -S option to allow a salt to be input on the command line. 8283 [Steve Henson] 8284 8285 *) New function X509_cmp(). Oddly enough there wasn't a function 8286 to compare two certificates. We do this by working out the SHA1 8287 hash and comparing that. X509_cmp() will be needed by the trust 8288 code. 8289 [Steve Henson] 8290 8291 *) SSL_get1_session() is like SSL_get_session(), but increments 8292 the reference count in the SSL_SESSION returned. 8293 [Geoff Thorpe <geoff@eu.c2.net>] 8294 8295 *) Fix for 'req': it was adding a null to request attributes. 8296 Also change the X509_LOOKUP and X509_INFO code to handle 8297 certificate auxiliary information. 8298 [Steve Henson] 8299 8300 *) Add support for 40 and 64 bit RC2 and RC4 algorithms: document 8301 the 'enc' command. 8302 [Steve Henson] 8303 8304 *) Add the possibility to add extra information to the memory leak 8305 detecting output, to form tracebacks, showing from where each 8306 allocation was originated: CRYPTO_push_info("constant string") adds 8307 the string plus current file name and line number to a per-thread 8308 stack, CRYPTO_pop_info() does the obvious, CRYPTO_remove_all_info() 8309 is like calling CYRPTO_pop_info() until the stack is empty. 8310 Also updated memory leak detection code to be multi-thread-safe. 8311 [Richard Levitte] 8312 8313 *) Add options -text and -noout to pkcs7 utility and delete the 8314 encryption options which never did anything. Update docs. 8315 [Steve Henson] 8316 8317 *) Add options to some of the utilities to allow the pass phrase 8318 to be included on either the command line (not recommended on 8319 OSes like Unix) or read from the environment. Update the 8320 manpages and fix a few bugs. 8321 [Steve Henson] 8322 8323 *) Add a few manpages for some of the openssl commands. 8324 [Steve Henson] 8325 8326 *) Fix the -revoke option in ca. It was freeing up memory twice, 8327 leaking and not finding already revoked certificates. 8328 [Steve Henson] 8329 8330 *) Extensive changes to support certificate auxiliary information. 8331 This involves the use of X509_CERT_AUX structure and X509_AUX 8332 functions. An X509_AUX function such as PEM_read_X509_AUX() 8333 can still read in a certificate file in the usual way but it 8334 will also read in any additional "auxiliary information". By 8335 doing things this way a fair degree of compatibility can be 8336 retained: existing certificates can have this information added 8337 using the new 'x509' options. 8338 8339 Current auxiliary information includes an "alias" and some trust 8340 settings. The trust settings will ultimately be used in enhanced 8341 certificate chain verification routines: currently a certificate 8342 can only be trusted if it is self signed and then it is trusted 8343 for all purposes. 8344 [Steve Henson] 8345 8346 *) Fix assembler for Alpha (tested only on DEC OSF not Linux or *BSD). 8347 The problem was that one of the replacement routines had not been working 8348 since SSLeay releases. For now the offending routine has been replaced 8349 with non-optimised assembler. Even so, this now gives around 95% 8350 performance improvement for 1024 bit RSA signs. 8351 [Mark Cox] 8352 8353 *) Hack to fix PKCS#7 decryption when used with some unorthodox RC2 8354 handling. Most clients have the effective key size in bits equal to 8355 the key length in bits: so a 40 bit RC2 key uses a 40 bit (5 byte) key. 8356 A few however don't do this and instead use the size of the decrypted key 8357 to determine the RC2 key length and the AlgorithmIdentifier to determine 8358 the effective key length. In this case the effective key length can still 8359 be 40 bits but the key length can be 168 bits for example. This is fixed 8360 by manually forcing an RC2 key into the EVP_PKEY structure because the 8361 EVP code can't currently handle unusual RC2 key sizes: it always assumes 8362 the key length and effective key length are equal. 8363 [Steve Henson] 8364 8365 *) Add a bunch of functions that should simplify the creation of 8366 X509_NAME structures. Now you should be able to do: 8367 X509_NAME_add_entry_by_txt(nm, "CN", MBSTRING_ASC, "Steve", -1, -1, 0); 8368 and have it automatically work out the correct field type and fill in 8369 the structures. The more adventurous can try: 8370 X509_NAME_add_entry_by_txt(nm, field, MBSTRING_UTF8, str, -1, -1, 0); 8371 and it will (hopefully) work out the correct multibyte encoding. 8372 [Steve Henson] 8373 8374 *) Change the 'req' utility to use the new field handling and multibyte 8375 copy routines. Before the DN field creation was handled in an ad hoc 8376 way in req, ca, and x509 which was rather broken and didn't support 8377 BMPStrings or UTF8Strings. Since some software doesn't implement 8378 BMPStrings or UTF8Strings yet, they can be enabled using the config file 8379 using the dirstring_type option. See the new comment in the default 8380 openssl.cnf for more info. 8381 [Steve Henson] 8382 8383 *) Make crypto/rand/md_rand.c more robust: 8384 - Assure unique random numbers after fork(). 8385 - Make sure that concurrent threads access the global counter and 8386 md serializably so that we never lose entropy in them 8387 or use exactly the same state in multiple threads. 8388 Access to the large state is not always serializable because 8389 the additional locking could be a performance killer, and 8390 md should be large enough anyway. 8391 [Bodo Moeller] 8392 8393 *) New file apps/app_rand.c with commonly needed functionality 8394 for handling the random seed file. 8395 8396 Use the random seed file in some applications that previously did not: 8397 ca, 8398 dsaparam -genkey (which also ignored its '-rand' option), 8399 s_client, 8400 s_server, 8401 x509 (when signing). 8402 Except on systems with /dev/urandom, it is crucial to have a random 8403 seed file at least for key creation, DSA signing, and for DH exchanges; 8404 for RSA signatures we could do without one. 8405 8406 gendh and gendsa (unlike genrsa) used to read only the first byte 8407 of each file listed in the '-rand' option. The function as previously 8408 found in genrsa is now in app_rand.c and is used by all programs 8409 that support '-rand'. 8410 [Bodo Moeller] 8411 8412 *) In RAND_write_file, use mode 0600 for creating files; 8413 don't just chmod when it may be too late. 8414 [Bodo Moeller] 8415 8416 *) Report an error from X509_STORE_load_locations 8417 when X509_LOOKUP_load_file or X509_LOOKUP_add_dir failed. 8418 [Bill Perry] 8419 8420 *) New function ASN1_mbstring_copy() this copies a string in either 8421 ASCII, Unicode, Universal (4 bytes per character) or UTF8 format 8422 into an ASN1_STRING type. A mask of permissible types is passed 8423 and it chooses the "minimal" type to use or an error if not type 8424 is suitable. 8425 [Steve Henson] 8426 8427 *) Add function equivalents to the various macros in asn1.h. The old 8428 macros are retained with an M_ prefix. Code inside the library can 8429 use the M_ macros. External code (including the openssl utility) 8430 should *NOT* in order to be "shared library friendly". 8431 [Steve Henson] 8432 8433 *) Add various functions that can check a certificate's extensions 8434 to see if it usable for various purposes such as SSL client, 8435 server or S/MIME and CAs of these types. This is currently 8436 VERY EXPERIMENTAL but will ultimately be used for certificate chain 8437 verification. Also added a -purpose flag to x509 utility to 8438 print out all the purposes. 8439 [Steve Henson] 8440 8441 *) Add a CRYPTO_EX_DATA to X509 certificate structure and associated 8442 functions. 8443 [Steve Henson] 8444 8445 *) New X509V3_{X509,CRL,REVOKED}_get_d2i() functions. These will search 8446 for, obtain and decode and extension and obtain its critical flag. 8447 This allows all the necessary extension code to be handled in a 8448 single function call. 8449 [Steve Henson] 8450 8451 *) RC4 tune-up featuring 30-40% performance improvement on most RISC 8452 platforms. See crypto/rc4/rc4_enc.c for further details. 8453 [Andy Polyakov] 8454 8455 *) New -noout option to asn1parse. This causes no output to be produced 8456 its main use is when combined with -strparse and -out to extract data 8457 from a file (which may not be in ASN.1 format). 8458 [Steve Henson] 8459 8460 *) Fix for pkcs12 program. It was hashing an invalid certificate pointer 8461 when producing the local key id. 8462 [Richard Levitte <levitte@stacken.kth.se>] 8463 8464 *) New option -dhparam in s_server. This allows a DH parameter file to be 8465 stated explicitly. If it is not stated then it tries the first server 8466 certificate file. The previous behaviour hard coded the filename 8467 "server.pem". 8468 [Steve Henson] 8469 8470 *) Add -pubin and -pubout options to the rsa and dsa commands. These allow 8471 a public key to be input or output. For example: 8472 openssl rsa -in key.pem -pubout -out pubkey.pem 8473 Also added necessary DSA public key functions to handle this. 8474 [Steve Henson] 8475 8476 *) Fix so PKCS7_dataVerify() doesn't crash if no certificates are contained 8477 in the message. This was handled by allowing 8478 X509_find_by_issuer_and_serial() to tolerate a NULL passed to it. 8479 [Steve Henson, reported by Sampo Kellomaki <sampo@mail.neuronio.pt>] 8480 8481 *) Fix for bug in d2i_ASN1_bytes(): other ASN1 functions add an extra null 8482 to the end of the strings whereas this didn't. This would cause problems 8483 if strings read with d2i_ASN1_bytes() were later modified. 8484 [Steve Henson, reported by Arne Ansper <arne@ats.cyber.ee>] 8485 8486 *) Fix for base64 decode bug. When a base64 bio reads only one line of 8487 data and it contains EOF it will end up returning an error. This is 8488 caused by input 46 bytes long. The cause is due to the way base64 8489 BIOs find the start of base64 encoded data. They do this by trying a 8490 trial decode on each line until they find one that works. When they 8491 do a flag is set and it starts again knowing it can pass all the 8492 data directly through the decoder. Unfortunately it doesn't reset 8493 the context it uses. This means that if EOF is reached an attempt 8494 is made to pass two EOFs through the context and this causes the 8495 resulting error. This can also cause other problems as well. As is 8496 usual with these problems it takes *ages* to find and the fix is 8497 trivial: move one line. 8498 [Steve Henson, reported by ian@uns.ns.ac.yu (Ivan Nejgebauer) ] 8499 8500 *) Ugly workaround to get s_client and s_server working under Windows. The 8501 old code wouldn't work because it needed to select() on sockets and the 8502 tty (for keypresses and to see if data could be written). Win32 only 8503 supports select() on sockets so we select() with a 1s timeout on the 8504 sockets and then see if any characters are waiting to be read, if none 8505 are present then we retry, we also assume we can always write data to 8506 the tty. This isn't nice because the code then blocks until we've 8507 received a complete line of data and it is effectively polling the 8508 keyboard at 1s intervals: however it's quite a bit better than not 8509 working at all :-) A dedicated Windows application might handle this 8510 with an event loop for example. 8511 [Steve Henson] 8512 8513 *) Enhance RSA_METHOD structure. Now there are two extra methods, rsa_sign 8514 and rsa_verify. When the RSA_FLAGS_SIGN_VER option is set these functions 8515 will be called when RSA_sign() and RSA_verify() are used. This is useful 8516 if rsa_pub_dec() and rsa_priv_enc() equivalents are not available. 8517 For this to work properly RSA_public_decrypt() and RSA_private_encrypt() 8518 should *not* be used: RSA_sign() and RSA_verify() must be used instead. 8519 This necessitated the support of an extra signature type NID_md5_sha1 8520 for SSL signatures and modifications to the SSL library to use it instead 8521 of calling RSA_public_decrypt() and RSA_private_encrypt(). 8522 [Steve Henson] 8523 8524 *) Add new -verify -CAfile and -CApath options to the crl program, these 8525 will lookup a CRL issuers certificate and verify the signature in a 8526 similar way to the verify program. Tidy up the crl program so it 8527 no longer accesses structures directly. Make the ASN1 CRL parsing a bit 8528 less strict. It will now permit CRL extensions even if it is not 8529 a V2 CRL: this will allow it to tolerate some broken CRLs. 8530 [Steve Henson] 8531 8532 *) Initialize all non-automatic variables each time one of the openssl 8533 sub-programs is started (this is necessary as they may be started 8534 multiple times from the "OpenSSL>" prompt). 8535 [Lennart Bang, Bodo Moeller] 8536 8537 *) Preliminary compilation option RSA_NULL which disables RSA crypto without 8538 removing all other RSA functionality (this is what NO_RSA does). This 8539 is so (for example) those in the US can disable those operations covered 8540 by the RSA patent while allowing storage and parsing of RSA keys and RSA 8541 key generation. 8542 [Steve Henson] 8543 8544 *) Non-copying interface to BIO pairs. 8545 (still largely untested) 8546 [Bodo Moeller] 8547 8548 *) New function ANS1_tag2str() to convert an ASN1 tag to a descriptive 8549 ASCII string. This was handled independently in various places before. 8550 [Steve Henson] 8551 8552 *) New functions UTF8_getc() and UTF8_putc() that parse and generate 8553 UTF8 strings a character at a time. 8554 [Steve Henson] 8555 8556 *) Use client_version from client hello to select the protocol 8557 (s23_srvr.c) and for RSA client key exchange verification 8558 (s3_srvr.c), as required by the SSL 3.0/TLS 1.0 specifications. 8559 [Bodo Moeller] 8560 8561 *) Add various utility functions to handle SPKACs, these were previously 8562 handled by poking round in the structure internals. Added new function 8563 NETSCAPE_SPKI_print() to print out SPKAC and a new utility 'spkac' to 8564 print, verify and generate SPKACs. Based on an original idea from 8565 Massimiliano Pala <madwolf@comune.modena.it> but extensively modified. 8566 [Steve Henson] 8567 8568 *) RIPEMD160 is operational on all platforms and is back in 'make test'. 8569 [Andy Polyakov] 8570 8571 *) Allow the config file extension section to be overwritten on the 8572 command line. Based on an original idea from Massimiliano Pala 8573 <madwolf@comune.modena.it>. The new option is called -extensions 8574 and can be applied to ca, req and x509. Also -reqexts to override 8575 the request extensions in req and -crlexts to override the crl extensions 8576 in ca. 8577 [Steve Henson] 8578 8579 *) Add new feature to the SPKAC handling in ca. Now you can include 8580 the same field multiple times by preceding it by "XXXX." for example: 8581 1.OU="Unit name 1" 8582 2.OU="Unit name 2" 8583 this is the same syntax as used in the req config file. 8584 [Steve Henson] 8585 8586 *) Allow certificate extensions to be added to certificate requests. These 8587 are specified in a 'req_extensions' option of the req section of the 8588 config file. They can be printed out with the -text option to req but 8589 are otherwise ignored at present. 8590 [Steve Henson] 8591 8592 *) Fix a horrible bug in enc_read() in crypto/evp/bio_enc.c: if the first 8593 data read consists of only the final block it would not decrypted because 8594 EVP_CipherUpdate() would correctly report zero bytes had been decrypted. 8595 A misplaced 'break' also meant the decrypted final block might not be 8596 copied until the next read. 8597 [Steve Henson] 8598 8599 *) Initial support for DH_METHOD. Again based on RSA_METHOD. Also added 8600 a few extra parameters to the DH structure: these will be useful if 8601 for example we want the value of 'q' or implement X9.42 DH. 8602 [Steve Henson] 8603 8604 *) Initial support for DSA_METHOD. This is based on the RSA_METHOD and 8605 provides hooks that allow the default DSA functions or functions on a 8606 "per key" basis to be replaced. This allows hardware acceleration and 8607 hardware key storage to be handled without major modification to the 8608 library. Also added low level modexp hooks and CRYPTO_EX structure and 8609 associated functions. 8610 [Steve Henson] 8611 8612 *) Add a new flag to memory BIOs, BIO_FLAG_MEM_RDONLY. This marks the BIO 8613 as "read only": it can't be written to and the buffer it points to will 8614 not be freed. Reading from a read only BIO is much more efficient than 8615 a normal memory BIO. This was added because there are several times when 8616 an area of memory needs to be read from a BIO. The previous method was 8617 to create a memory BIO and write the data to it, this results in two 8618 copies of the data and an O(n^2) reading algorithm. There is a new 8619 function BIO_new_mem_buf() which creates a read only memory BIO from 8620 an area of memory. Also modified the PKCS#7 routines to use read only 8621 memory BIOs. 8622 [Steve Henson] 8623 8624 *) Bugfix: ssl23_get_client_hello did not work properly when called in 8625 state SSL23_ST_SR_CLNT_HELLO_B, i.e. when the first 7 bytes of 8626 a SSLv2-compatible client hello for SSLv3 or TLSv1 could be read, 8627 but a retry condition occured while trying to read the rest. 8628 [Bodo Moeller] 8629 8630 *) The PKCS7_ENC_CONTENT_new() function was setting the content type as 8631 NID_pkcs7_encrypted by default: this was wrong since this should almost 8632 always be NID_pkcs7_data. Also modified the PKCS7_set_type() to handle 8633 the encrypted data type: this is a more sensible place to put it and it 8634 allows the PKCS#12 code to be tidied up that duplicated this 8635 functionality. 8636 [Steve Henson] 8637 8638 *) Changed obj_dat.pl script so it takes its input and output files on 8639 the command line. This should avoid shell escape redirection problems 8640 under Win32. 8641 [Steve Henson] 8642 8643 *) Initial support for certificate extension requests, these are included 8644 in things like Xenroll certificate requests. Included functions to allow 8645 extensions to be obtained and added. 8646 [Steve Henson] 8647 8648 *) -crlf option to s_client and s_server for sending newlines as 8649 CRLF (as required by many protocols). 8650 [Bodo Moeller] 8651 8652 Changes between 0.9.3a and 0.9.4 [09 Aug 1999] 8653 8654 *) Install libRSAglue.a when OpenSSL is built with RSAref. 8655 [Ralf S. Engelschall] 8656 8657 *) A few more ``#ifndef NO_FP_API / #endif'' pairs for consistency. 8658 [Andrija Antonijevic <TheAntony2@bigfoot.com>] 8659 8660 *) Fix -startdate and -enddate (which was missing) arguments to 'ca' 8661 program. 8662 [Steve Henson] 8663 8664 *) New function DSA_dup_DH, which duplicates DSA parameters/keys as 8665 DH parameters/keys (q is lost during that conversion, but the resulting 8666 DH parameters contain its length). 8667 8668 For 1024-bit p, DSA_generate_parameters followed by DSA_dup_DH is 8669 much faster than DH_generate_parameters (which creates parameters 8670 where p = 2*q + 1), and also the smaller q makes DH computations 8671 much more efficient (160-bit exponentiation instead of 1024-bit 8672 exponentiation); so this provides a convenient way to support DHE 8673 ciphersuites in SSL/TLS servers (see ssl/ssltest.c). It is of 8674 utter importance to use 8675 SSL_CTX_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); 8676 or 8677 SSL_set_options(s_ctx, SSL_OP_SINGLE_DH_USE); 8678 when such DH parameters are used, because otherwise small subgroup 8679 attacks may become possible! 8680 [Bodo Moeller] 8681 8682 *) Avoid memory leak in i2d_DHparams. 8683 [Bodo Moeller] 8684 8685 *) Allow the -k option to be used more than once in the enc program: 8686 this allows the same encrypted message to be read by multiple recipients. 8687 [Steve Henson] 8688 8689 *) New function OBJ_obj2txt(buf, buf_len, a, no_name), this converts 8690 an ASN1_OBJECT to a text string. If the "no_name" parameter is set then 8691 it will always use the numerical form of the OID, even if it has a short 8692 or long name. 8693 [Steve Henson] 8694 8695 *) Added an extra RSA flag: RSA_FLAG_EXT_PKEY. Previously the rsa_mod_exp 8696 method only got called if p,q,dmp1,dmq1,iqmp components were present, 8697 otherwise bn_mod_exp was called. In the case of hardware keys for example 8698 no private key components need be present and it might store extra data 8699 in the RSA structure, which cannot be accessed from bn_mod_exp. 8700 By setting RSA_FLAG_EXT_PKEY rsa_mod_exp will always be called for 8701 private key operations. 8702 [Steve Henson] 8703 8704 *) Added support for SPARC Linux. 8705 [Andy Polyakov] 8706 8707 *) pem_password_cb function type incompatibly changed from 8708 typedef int pem_password_cb(char *buf, int size, int rwflag); 8709 to 8710 ....(char *buf, int size, int rwflag, void *userdata); 8711 so that applications can pass data to their callbacks: 8712 The PEM[_ASN1]_{read,write}... functions and macros now take an 8713 additional void * argument, which is just handed through whenever 8714 the password callback is called. 8715 [Damien Miller <dmiller@ilogic.com.au>; tiny changes by Bodo Moeller] 8716 8717 New function SSL_CTX_set_default_passwd_cb_userdata. 8718 8719 Compatibility note: As many C implementations push function arguments 8720 onto the stack in reverse order, the new library version is likely to 8721 interoperate with programs that have been compiled with the old 8722 pem_password_cb definition (PEM_whatever takes some data that 8723 happens to be on the stack as its last argument, and the callback 8724 just ignores this garbage); but there is no guarantee whatsoever that 8725 this will work. 8726 8727 *) The -DPLATFORM="\"$(PLATFORM)\"" definition and the similar -DCFLAGS=... 8728 (both in crypto/Makefile.ssl for use by crypto/cversion.c) caused 8729 problems not only on Windows, but also on some Unix platforms. 8730 To avoid problematic command lines, these definitions are now in an 8731 auto-generated file crypto/buildinf.h (created by crypto/Makefile.ssl 8732 for standard "make" builds, by util/mk1mf.pl for "mk1mf" builds). 8733 [Bodo Moeller] 8734 8735 *) MIPS III/IV assembler module is reimplemented. 8736 [Andy Polyakov] 8737 8738 *) More DES library cleanups: remove references to srand/rand and 8739 delete an unused file. 8740 [Ulf M�ller] 8741 8742 *) Add support for the the free Netwide assembler (NASM) under Win32, 8743 since not many people have MASM (ml) and it can be hard to obtain. 8744 This is currently experimental but it seems to work OK and pass all 8745 the tests. Check out INSTALL.W32 for info. 8746 [Steve Henson] 8747 8748 *) Fix memory leaks in s3_clnt.c: All non-anonymous SSL3/TLS1 connections 8749 without temporary keys kept an extra copy of the server key, 8750 and connections with temporary keys did not free everything in case 8751 of an error. 8752 [Bodo Moeller] 8753 8754 *) New function RSA_check_key and new openssl rsa option -check 8755 for verifying the consistency of RSA keys. 8756 [Ulf Moeller, Bodo Moeller] 8757 8758 *) Various changes to make Win32 compile work: 8759 1. Casts to avoid "loss of data" warnings in p5_crpt2.c 8760 2. Change unsigned int to int in b_dump.c to avoid "signed/unsigned 8761 comparison" warnings. 8762 3. Add sk_<TYPE>_sort to DEF file generator and do make update. 8763 [Steve Henson] 8764 8765 *) Add a debugging option to PKCS#5 v2 key generation function: when 8766 you #define DEBUG_PKCS5V2 passwords, salts, iteration counts and 8767 derived keys are printed to stderr. 8768 [Steve Henson] 8769 8770 *) Copy the flags in ASN1_STRING_dup(). 8771 [Roman E. Pavlov <pre@mo.msk.ru>] 8772 8773 *) The x509 application mishandled signing requests containing DSA 8774 keys when the signing key was also DSA and the parameters didn't match. 8775 8776 It was supposed to omit the parameters when they matched the signing key: 8777 the verifying software was then supposed to automatically use the CA's 8778 parameters if they were absent from the end user certificate. 8779 8780 Omitting parameters is no longer recommended. The test was also 8781 the wrong way round! This was probably due to unusual behaviour in 8782 EVP_cmp_parameters() which returns 1 if the parameters match. 8783 This meant that parameters were omitted when they *didn't* match and 8784 the certificate was useless. Certificates signed with 'ca' didn't have 8785 this bug. 8786 [Steve Henson, reported by Doug Erickson <Doug.Erickson@Part.NET>] 8787 8788 *) Memory leak checking (-DCRYPTO_MDEBUG) had some problems. 8789 The interface is as follows: 8790 Applications can use 8791 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ON) aka MemCheck_start(), 8792 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_OFF) aka MemCheck_stop(); 8793 "off" is now the default. 8794 The library internally uses 8795 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_DISABLE) aka MemCheck_off(), 8796 CRYPTO_mem_ctrl(CRYPTO_MEM_CHECK_ENABLE) aka MemCheck_on() 8797 to disable memory-checking temporarily. 8798 8799 Some inconsistent states that previously were possible (and were 8800 even the default) are now avoided. 8801 8802 -DCRYPTO_MDEBUG_TIME is new and additionally stores the current time 8803 with each memory chunk allocated; this is occasionally more helpful 8804 than just having a counter. 8805 8806 -DCRYPTO_MDEBUG_THREAD is also new and adds the thread ID. 8807 8808 -DCRYPTO_MDEBUG_ALL enables all of the above, plus any future 8809 extensions. 8810 [Bodo Moeller] 8811 8812 *) Introduce "mode" for SSL structures (with defaults in SSL_CTX), 8813 which largely parallels "options", but is for changing API behaviour, 8814 whereas "options" are about protocol behaviour. 8815 Initial "mode" flags are: 8816 8817 SSL_MODE_ENABLE_PARTIAL_WRITE Allow SSL_write to report success when 8818 a single record has been written. 8819 SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER Don't insist that SSL_write 8820 retries use the same buffer location. 8821 (But all of the contents must be 8822 copied!) 8823 [Bodo Moeller] 8824 8825 *) Bugfix: SSL_set_options ignored its parameter, only SSL_CTX_set_options 8826 worked. 8827 8828 *) Fix problems with no-hmac etc. 8829 [Ulf M�ller, pointed out by Brian Wellington <bwelling@tislabs.com>] 8830 8831 *) New functions RSA_get_default_method(), RSA_set_method() and 8832 RSA_get_method(). These allows replacement of RSA_METHODs without having 8833 to mess around with the internals of an RSA structure. 8834 [Steve Henson] 8835 8836 *) Fix memory leaks in DSA_do_sign and DSA_is_prime. 8837 Also really enable memory leak checks in openssl.c and in some 8838 test programs. 8839 [Chad C. Mulligan, Bodo Moeller] 8840 8841 *) Fix a bug in d2i_ASN1_INTEGER() and i2d_ASN1_INTEGER() which can mess 8842 up the length of negative integers. This has now been simplified to just 8843 store the length when it is first determined and use it later, rather 8844 than trying to keep track of where data is copied and updating it to 8845 point to the end. 8846 [Steve Henson, reported by Brien Wheeler 8847 <bwheeler@authentica-security.com>] 8848 8849 *) Add a new function PKCS7_signatureVerify. This allows the verification 8850 of a PKCS#7 signature but with the signing certificate passed to the 8851 function itself. This contrasts with PKCS7_dataVerify which assumes the 8852 certificate is present in the PKCS#7 structure. This isn't always the 8853 case: certificates can be omitted from a PKCS#7 structure and be 8854 distributed by "out of band" means (such as a certificate database). 8855 [Steve Henson] 8856 8857 *) Complete the PEM_* macros with DECLARE_PEM versions to replace the 8858 function prototypes in pem.h, also change util/mkdef.pl to add the 8859 necessary function names. 8860 [Steve Henson] 8861 8862 *) mk1mf.pl (used by Windows builds) did not properly read the 8863 options set by Configure in the top level Makefile, and Configure 8864 was not even able to write more than one option correctly. 8865 Fixed, now "no-idea no-rc5 -DCRYPTO_MDEBUG" etc. works as intended. 8866 [Bodo Moeller] 8867 8868 *) New functions CONF_load_bio() and CONF_load_fp() to allow a config 8869 file to be loaded from a BIO or FILE pointer. The BIO version will 8870 for example allow memory BIOs to contain config info. 8871 [Steve Henson] 8872 8873 *) New function "CRYPTO_num_locks" that returns CRYPTO_NUM_LOCKS. 8874 Whoever hopes to achieve shared-library compatibility across versions 8875 must use this, not the compile-time macro. 8876 (Exercise 0.9.4: Which is the minimum library version required by 8877 such programs?) 8878 Note: All this applies only to multi-threaded programs, others don't 8879 need locks. 8880 [Bodo Moeller] 8881 8882 *) Add missing case to s3_clnt.c state machine -- one of the new SSL tests 8883 through a BIO pair triggered the default case, i.e. 8884 SSLerr(...,SSL_R_UNKNOWN_STATE). 8885 [Bodo Moeller] 8886 8887 *) New "BIO pair" concept (crypto/bio/bss_bio.c) so that applications 8888 can use the SSL library even if none of the specific BIOs is 8889 appropriate. 8890 [Bodo Moeller] 8891 8892 *) Fix a bug in i2d_DSAPublicKey() which meant it returned the wrong value 8893 for the encoded length. 8894 [Jeon KyoungHo <khjeon@sds.samsung.co.kr>] 8895 8896 *) Add initial documentation of the X509V3 functions. 8897 [Steve Henson] 8898 8899 *) Add a new pair of functions PEM_write_PKCS8PrivateKey() and 8900 PEM_write_bio_PKCS8PrivateKey() that are equivalent to 8901 PEM_write_PrivateKey() and PEM_write_bio_PrivateKey() but use the more 8902 secure PKCS#8 private key format with a high iteration count. 8903 [Steve Henson] 8904 8905 *) Fix determination of Perl interpreter: A perl or perl5 8906 _directory_ in $PATH was also accepted as the interpreter. 8907 [Ralf S. Engelschall] 8908 8909 *) Fix demos/sign/sign.c: well there wasn't anything strictly speaking 8910 wrong with it but it was very old and did things like calling 8911 PEM_ASN1_read() directly and used MD5 for the hash not to mention some 8912 unusual formatting. 8913 [Steve Henson] 8914 8915 *) Fix demos/selfsign.c: it used obsolete and deleted functions, changed 8916 to use the new extension code. 8917 [Steve Henson] 8918 8919 *) Implement the PEM_read/PEM_write functions in crypto/pem/pem_all.c 8920 with macros. This should make it easier to change their form, add extra 8921 arguments etc. Fix a few PEM prototypes which didn't have cipher as a 8922 constant. 8923 [Steve Henson] 8924 8925 *) Add to configuration table a new entry that can specify an alternative 8926 name for unistd.h (for pre-POSIX systems); we need this for NeXTstep, 8927 according to Mark Crispin <MRC@Panda.COM>. 8928 [Bodo Moeller] 8929 8930#if 0 8931 *) DES CBC did not update the IV. Weird. 8932 [Ben Laurie] 8933#else 8934 des_cbc_encrypt does not update the IV, but des_ncbc_encrypt does. 8935 Changing the behaviour of the former might break existing programs -- 8936 where IV updating is needed, des_ncbc_encrypt can be used. 8937#endif 8938 8939 *) When bntest is run from "make test" it drives bc to check its 8940 calculations, as well as internally checking them. If an internal check 8941 fails, it needs to cause bc to give a non-zero result or make test carries 8942 on without noticing the failure. Fixed. 8943 [Ben Laurie] 8944 8945 *) DES library cleanups. 8946 [Ulf M�ller] 8947 8948 *) Add support for PKCS#5 v2.0 PBE algorithms. This will permit PKCS#8 to be 8949 used with any cipher unlike PKCS#5 v1.5 which can at most handle 64 bit 8950 ciphers. NOTE: although the key derivation function has been verified 8951 against some published test vectors it has not been extensively tested 8952 yet. Added a -v2 "cipher" option to pkcs8 application to allow the use 8953 of v2.0. 8954 [Steve Henson] 8955 8956 *) Instead of "mkdir -p", which is not fully portable, use new 8957 Perl script "util/mkdir-p.pl". 8958 [Bodo Moeller] 8959 8960 *) Rewrite the way password based encryption (PBE) is handled. It used to 8961 assume that the ASN1 AlgorithmIdentifier parameter was a PBEParameter 8962 structure. This was true for the PKCS#5 v1.5 and PKCS#12 PBE algorithms 8963 but doesn't apply to PKCS#5 v2.0 where it can be something else. Now 8964 the 'parameter' field of the AlgorithmIdentifier is passed to the 8965 underlying key generation function so it must do its own ASN1 parsing. 8966 This has also changed the EVP_PBE_CipherInit() function which now has a 8967 'parameter' argument instead of literal salt and iteration count values 8968 and the function EVP_PBE_ALGOR_CipherInit() has been deleted. 8969 [Steve Henson] 8970 8971 *) Support for PKCS#5 v1.5 compatible password based encryption algorithms 8972 and PKCS#8 functionality. New 'pkcs8' application linked to openssl. 8973 Needed to change the PEM_STRING_EVP_PKEY value which was just "PRIVATE 8974 KEY" because this clashed with PKCS#8 unencrypted string. Since this 8975 value was just used as a "magic string" and not used directly its 8976 value doesn't matter. 8977 [Steve Henson] 8978 8979 *) Introduce some semblance of const correctness to BN. Shame C doesn't 8980 support mutable. 8981 [Ben Laurie] 8982 8983 *) "linux-sparc64" configuration (ultrapenguin). 8984 [Ray Miller <ray.miller@oucs.ox.ac.uk>] 8985 "linux-sparc" configuration. 8986 [Christian Forster <fo@hawo.stw.uni-erlangen.de>] 8987 8988 *) config now generates no-xxx options for missing ciphers. 8989 [Ulf M�ller] 8990 8991 *) Support the EBCDIC character set (work in progress). 8992 File ebcdic.c not yet included because it has a different license. 8993 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] 8994 8995 *) Support BS2000/OSD-POSIX. 8996 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>] 8997 8998 *) Make callbacks for key generation use void * instead of char *. 8999 [Ben Laurie] 9000 9001 *) Make S/MIME samples compile (not yet tested). 9002 [Ben Laurie] 9003 9004 *) Additional typesafe stacks. 9005 [Ben Laurie] 9006 9007 *) New configuration variants "bsdi-elf-gcc" (BSD/OS 4.x). 9008 [Bodo Moeller] 9009 9010 9011 Changes between 0.9.3 and 0.9.3a [29 May 1999] 9012 9013 *) New configuration variant "sco5-gcc". 9014 9015 *) Updated some demos. 9016 [Sean O Riordain, Wade Scholine] 9017 9018 *) Add missing BIO_free at exit of pkcs12 application. 9019 [Wu Zhigang] 9020 9021 *) Fix memory leak in conf.c. 9022 [Steve Henson] 9023 9024 *) Updates for Win32 to assembler version of MD5. 9025 [Steve Henson] 9026 9027 *) Set #! path to perl in apps/der_chop to where we found it 9028 instead of using a fixed path. 9029 [Bodo Moeller] 9030 9031 *) SHA library changes for irix64-mips4-cc. 9032 [Andy Polyakov] 9033 9034 *) Improvements for VMS support. 9035 [Richard Levitte] 9036 9037 9038 Changes between 0.9.2b and 0.9.3 [24 May 1999] 9039 9040 *) Bignum library bug fix. IRIX 6 passes "make test" now! 9041 This also avoids the problems with SC4.2 and unpatched SC5. 9042 [Andy Polyakov <appro@fy.chalmers.se>] 9043 9044 *) New functions sk_num, sk_value and sk_set to replace the previous macros. 9045 These are required because of the typesafe stack would otherwise break 9046 existing code. If old code used a structure member which used to be STACK 9047 and is now STACK_OF (for example cert in a PKCS7_SIGNED structure) with 9048 sk_num or sk_value it would produce an error because the num, data members 9049 are not present in STACK_OF. Now it just produces a warning. sk_set 9050 replaces the old method of assigning a value to sk_value 9051 (e.g. sk_value(x, i) = y) which the library used in a few cases. Any code 9052 that does this will no longer work (and should use sk_set instead) but 9053 this could be regarded as a "questionable" behaviour anyway. 9054 [Steve Henson] 9055 9056 *) Fix most of the other PKCS#7 bugs. The "experimental" code can now 9057 correctly handle encrypted S/MIME data. 9058 [Steve Henson] 9059 9060 *) Change type of various DES function arguments from des_cblock 9061 (which means, in function argument declarations, pointer to char) 9062 to des_cblock * (meaning pointer to array with 8 char elements), 9063 which allows the compiler to do more typechecking; it was like 9064 that back in SSLeay, but with lots of ugly casts. 9065 9066 Introduce new type const_des_cblock. 9067 [Bodo Moeller] 9068 9069 *) Reorganise the PKCS#7 library and get rid of some of the more obvious 9070 problems: find RecipientInfo structure that matches recipient certificate 9071 and initialise the ASN1 structures properly based on passed cipher. 9072 [Steve Henson] 9073 9074 *) Belatedly make the BN tests actually check the results. 9075 [Ben Laurie] 9076 9077 *) Fix the encoding and decoding of negative ASN1 INTEGERS and conversion 9078 to and from BNs: it was completely broken. New compilation option 9079 NEG_PUBKEY_BUG to allow for some broken certificates that encode public 9080 key elements as negative integers. 9081 [Steve Henson] 9082 9083 *) Reorganize and speed up MD5. 9084 [Andy Polyakov <appro@fy.chalmers.se>] 9085 9086 *) VMS support. 9087 [Richard Levitte <richard@levitte.org>] 9088 9089 *) New option -out to asn1parse to allow the parsed structure to be 9090 output to a file. This is most useful when combined with the -strparse 9091 option to examine the output of things like OCTET STRINGS. 9092 [Steve Henson] 9093 9094 *) Make SSL library a little more fool-proof by not requiring any longer 9095 that SSL_set_{accept,connect}_state be called before 9096 SSL_{accept,connect} may be used (SSL_set_..._state is omitted 9097 in many applications because usually everything *appeared* to work as 9098 intended anyway -- now it really works as intended). 9099 [Bodo Moeller] 9100 9101 *) Move openssl.cnf out of lib/. 9102 [Ulf M�ller] 9103 9104 *) Fix various things to let OpenSSL even pass ``egcc -pipe -O2 -Wall 9105 -Wshadow -Wpointer-arith -Wcast-align -Wmissing-prototypes 9106 -Wmissing-declarations -Wnested-externs -Winline'' with EGCS 1.1.2+ 9107 [Ralf S. Engelschall] 9108 9109 *) Various fixes to the EVP and PKCS#7 code. It may now be able to 9110 handle PKCS#7 enveloped data properly. 9111 [Sebastian Akerman <sak@parallelconsulting.com>, modified by Steve] 9112 9113 *) Create a duplicate of the SSL_CTX's CERT in SSL_new instead of 9114 copying pointers. The cert_st handling is changed by this in 9115 various ways (and thus what used to be known as ctx->default_cert 9116 is now called ctx->cert, since we don't resort to s->ctx->[default_]cert 9117 any longer when s->cert does not give us what we need). 9118 ssl_cert_instantiate becomes obsolete by this change. 9119 As soon as we've got the new code right (possibly it already is?), 9120 we have solved a couple of bugs of the earlier code where s->cert 9121 was used as if it could not have been shared with other SSL structures. 9122 9123 Note that using the SSL API in certain dirty ways now will result 9124 in different behaviour than observed with earlier library versions: 9125 Changing settings for an SSL_CTX *ctx after having done s = SSL_new(ctx) 9126 does not influence s as it used to. 9127 9128 In order to clean up things more thoroughly, inside SSL_SESSION 9129 we don't use CERT any longer, but a new structure SESS_CERT 9130 that holds per-session data (if available); currently, this is 9131 the peer's certificate chain and, for clients, the server's certificate 9132 and temporary key. CERT holds only those values that can have 9133 meaningful defaults in an SSL_CTX. 9134 [Bodo Moeller] 9135 9136 *) New function X509V3_EXT_i2d() to create an X509_EXTENSION structure 9137 from the internal representation. Various PKCS#7 fixes: remove some 9138 evil casts and set the enc_dig_alg field properly based on the signing 9139 key type. 9140 [Steve Henson] 9141 9142 *) Allow PKCS#12 password to be set from the command line or the 9143 environment. Let 'ca' get its config file name from the environment 9144 variables "OPENSSL_CONF" or "SSLEAY_CONF" (for consistency with 'req' 9145 and 'x509'). 9146 [Steve Henson] 9147 9148 *) Allow certificate policies extension to use an IA5STRING for the 9149 organization field. This is contrary to the PKIX definition but 9150 VeriSign uses it and IE5 only recognises this form. Document 'x509' 9151 extension option. 9152 [Steve Henson] 9153 9154 *) Add PEDANTIC compiler flag to allow compilation with gcc -pedantic, 9155 without disallowing inline assembler and the like for non-pedantic builds. 9156 [Ben Laurie] 9157 9158 *) Support Borland C++ builder. 9159 [Janez Jere <jj@void.si>, modified by Ulf M�ller] 9160 9161 *) Support Mingw32. 9162 [Ulf M�ller] 9163 9164 *) SHA-1 cleanups and performance enhancements. 9165 [Andy Polyakov <appro@fy.chalmers.se>] 9166 9167 *) Sparc v8plus assembler for the bignum library. 9168 [Andy Polyakov <appro@fy.chalmers.se>] 9169 9170 *) Accept any -xxx and +xxx compiler options in Configure. 9171 [Ulf M�ller] 9172 9173 *) Update HPUX configuration. 9174 [Anonymous] 9175 9176 *) Add missing sk_<type>_unshift() function to safestack.h 9177 [Ralf S. Engelschall] 9178 9179 *) New function SSL_CTX_use_certificate_chain_file that sets the 9180 "extra_cert"s in addition to the certificate. (This makes sense 9181 only for "PEM" format files, as chains as a whole are not 9182 DER-encoded.) 9183 [Bodo Moeller] 9184 9185 *) Support verify_depth from the SSL API. 9186 x509_vfy.c had what can be considered an off-by-one-error: 9187 Its depth (which was not part of the external interface) 9188 was actually counting the number of certificates in a chain; 9189 now it really counts the depth. 9190 [Bodo Moeller] 9191 9192 *) Bugfix in crypto/x509/x509_cmp.c: The SSLerr macro was used 9193 instead of X509err, which often resulted in confusing error 9194 messages since the error codes are not globally unique 9195 (e.g. an alleged error in ssl3_accept when a certificate 9196 didn't match the private key). 9197 9198 *) New function SSL_CTX_set_session_id_context that allows to set a default 9199 value (so that you don't need SSL_set_session_id_context for each 9200 connection using the SSL_CTX). 9201 [Bodo Moeller] 9202 9203 *) OAEP decoding bug fix. 9204 [Ulf M�ller] 9205 9206 *) Support INSTALL_PREFIX for package builders, as proposed by 9207 David Harris. 9208 [Bodo Moeller] 9209 9210 *) New Configure options "threads" and "no-threads". For systems 9211 where the proper compiler options are known (currently Solaris 9212 and Linux), "threads" is the default. 9213 [Bodo Moeller] 9214 9215 *) New script util/mklink.pl as a faster substitute for util/mklink.sh. 9216 [Bodo Moeller] 9217 9218 *) Install various scripts to $(OPENSSLDIR)/misc, not to 9219 $(INSTALLTOP)/bin -- they shouldn't clutter directories 9220 such as /usr/local/bin. 9221 [Bodo Moeller] 9222 9223 *) "make linux-shared" to build shared libraries. 9224 [Niels Poppe <niels@netbox.org>] 9225 9226 *) New Configure option no-<cipher> (rsa, idea, rc5, ...). 9227 [Ulf M�ller] 9228 9229 *) Add the PKCS#12 API documentation to openssl.txt. Preliminary support for 9230 extension adding in x509 utility. 9231 [Steve Henson] 9232 9233 *) Remove NOPROTO sections and error code comments. 9234 [Ulf M�ller] 9235 9236 *) Partial rewrite of the DEF file generator to now parse the ANSI 9237 prototypes. 9238 [Steve Henson] 9239 9240 *) New Configure options --prefix=DIR and --openssldir=DIR. 9241 [Ulf M�ller] 9242 9243 *) Complete rewrite of the error code script(s). It is all now handled 9244 by one script at the top level which handles error code gathering, 9245 header rewriting and C source file generation. It should be much better 9246 than the old method: it now uses a modified version of Ulf's parser to 9247 read the ANSI prototypes in all header files (thus the old K&R definitions 9248 aren't needed for error creation any more) and do a better job of 9249 translating function codes into names. The old 'ASN1 error code imbedded 9250 in a comment' is no longer necessary and it doesn't use .err files which 9251 have now been deleted. Also the error code call doesn't have to appear all 9252 on one line (which resulted in some large lines...). 9253 [Steve Henson] 9254 9255 *) Change #include filenames from <foo.h> to <openssl/foo.h>. 9256 [Bodo Moeller] 9257 9258 *) Change behaviour of ssl2_read when facing length-0 packets: Don't return 9259 0 (which usually indicates a closed connection), but continue reading. 9260 [Bodo Moeller] 9261 9262 *) Fix some race conditions. 9263 [Bodo Moeller] 9264 9265 *) Add support for CRL distribution points extension. Add Certificate 9266 Policies and CRL distribution points documentation. 9267 [Steve Henson] 9268 9269 *) Move the autogenerated header file parts to crypto/opensslconf.h. 9270 [Ulf M�ller] 9271 9272 *) Fix new 56-bit DES export ciphersuites: they were using 7 bytes instead of 9273 8 of keying material. Merlin has also confirmed interop with this fix 9274 between OpenSSL and Baltimore C/SSL 2.0 and J/SSL 2.0. 9275 [Merlin Hughes <merlin@baltimore.ie>] 9276 9277 *) Fix lots of warnings. 9278 [Richard Levitte <levitte@stacken.kth.se>] 9279 9280 *) In add_cert_dir() in crypto/x509/by_dir.c, break out of the loop if 9281 the directory spec didn't end with a LIST_SEPARATOR_CHAR. 9282 [Richard Levitte <levitte@stacken.kth.se>] 9283 9284 *) Fix problems with sizeof(long) == 8. 9285 [Andy Polyakov <appro@fy.chalmers.se>] 9286 9287 *) Change functions to ANSI C. 9288 [Ulf M�ller] 9289 9290 *) Fix typos in error codes. 9291 [Martin Kraemer <Martin.Kraemer@MchP.Siemens.De>, Ulf M�ller] 9292 9293 *) Remove defunct assembler files from Configure. 9294 [Ulf M�ller] 9295 9296 *) SPARC v8 assembler BIGNUM implementation. 9297 [Andy Polyakov <appro@fy.chalmers.se>] 9298 9299 *) Support for Certificate Policies extension: both print and set. 9300 Various additions to support the r2i method this uses. 9301 [Steve Henson] 9302 9303 *) A lot of constification, and fix a bug in X509_NAME_oneline() that could 9304 return a const string when you are expecting an allocated buffer. 9305 [Ben Laurie] 9306 9307 *) Add support for ASN1 types UTF8String and VISIBLESTRING, also the CHOICE 9308 types DirectoryString and DisplayText. 9309 [Steve Henson] 9310 9311 *) Add code to allow r2i extensions to access the configuration database, 9312 add an LHASH database driver and add several ctx helper functions. 9313 [Steve Henson] 9314 9315 *) Fix an evil bug in bn_expand2() which caused various BN functions to 9316 fail when they extended the size of a BIGNUM. 9317 [Steve Henson] 9318 9319 *) Various utility functions to handle SXNet extension. Modify mkdef.pl to 9320 support typesafe stack. 9321 [Steve Henson] 9322 9323 *) Fix typo in SSL_[gs]et_options(). 9324 [Nils Frostberg <nils@medcom.se>] 9325 9326 *) Delete various functions and files that belonged to the (now obsolete) 9327 old X509V3 handling code. 9328 [Steve Henson] 9329 9330 *) New Configure option "rsaref". 9331 [Ulf M�ller] 9332 9333 *) Don't auto-generate pem.h. 9334 [Bodo Moeller] 9335 9336 *) Introduce type-safe ASN.1 SETs. 9337 [Ben Laurie] 9338 9339 *) Convert various additional casted stacks to type-safe STACK_OF() variants. 9340 [Ben Laurie, Ralf S. Engelschall, Steve Henson] 9341 9342 *) Introduce type-safe STACKs. This will almost certainly break lots of code 9343 that links with OpenSSL (well at least cause lots of warnings), but fear 9344 not: the conversion is trivial, and it eliminates loads of evil casts. A 9345 few STACKed things have been converted already. Feel free to convert more. 9346 In the fullness of time, I'll do away with the STACK type altogether. 9347 [Ben Laurie] 9348 9349 *) Add `openssl ca -revoke <certfile>' facility which revokes a certificate 9350 specified in <certfile> by updating the entry in the index.txt file. 9351 This way one no longer has to edit the index.txt file manually for 9352 revoking a certificate. The -revoke option does the gory details now. 9353 [Massimiliano Pala <madwolf@openca.org>, Ralf S. Engelschall] 9354 9355 *) Fix `openssl crl -noout -text' combination where `-noout' killed the 9356 `-text' option at all and this way the `-noout -text' combination was 9357 inconsistent in `openssl crl' with the friends in `openssl x509|rsa|dsa'. 9358 [Ralf S. Engelschall] 9359 9360 *) Make sure a corresponding plain text error message exists for the 9361 X509_V_ERR_CERT_REVOKED/23 error number which can occur when a 9362 verify callback function determined that a certificate was revoked. 9363 [Ralf S. Engelschall] 9364 9365 *) Bugfix: In test/testenc, don't test "openssl <cipher>" for 9366 ciphers that were excluded, e.g. by -DNO_IDEA. Also, test 9367 all available cipers including rc5, which was forgotten until now. 9368 In order to let the testing shell script know which algorithms 9369 are available, a new (up to now undocumented) command 9370 "openssl list-cipher-commands" is used. 9371 [Bodo Moeller] 9372 9373 *) Bugfix: s_client occasionally would sleep in select() when 9374 it should have checked SSL_pending() first. 9375 [Bodo Moeller] 9376 9377 *) New functions DSA_do_sign and DSA_do_verify to provide access to 9378 the raw DSA values prior to ASN.1 encoding. 9379 [Ulf M�ller] 9380 9381 *) Tweaks to Configure 9382 [Niels Poppe <niels@netbox.org>] 9383 9384 *) Add support for PKCS#5 v2.0 ASN1 PBES2 structures. No other support, 9385 yet... 9386 [Steve Henson] 9387 9388 *) New variables $(RANLIB) and $(PERL) in the Makefiles. 9389 [Ulf M�ller] 9390 9391 *) New config option to avoid instructions that are illegal on the 80386. 9392 The default code is faster, but requires at least a 486. 9393 [Ulf M�ller] 9394 9395 *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and 9396 SSL2_SERVER_VERSION (not used at all) macros, which are now the 9397 same as SSL2_VERSION anyway. 9398 [Bodo Moeller] 9399 9400 *) New "-showcerts" option for s_client. 9401 [Bodo Moeller] 9402 9403 *) Still more PKCS#12 integration. Add pkcs12 application to openssl 9404 application. Various cleanups and fixes. 9405 [Steve Henson] 9406 9407 *) More PKCS#12 integration. Add new pkcs12 directory with Makefile.ssl and 9408 modify error routines to work internally. Add error codes and PBE init 9409 to library startup routines. 9410 [Steve Henson] 9411 9412 *) Further PKCS#12 integration. Added password based encryption, PKCS#8 and 9413 packing functions to asn1 and evp. Changed function names and error 9414 codes along the way. 9415 [Steve Henson] 9416 9417 *) PKCS12 integration: and so it begins... First of several patches to 9418 slowly integrate PKCS#12 functionality into OpenSSL. Add PKCS#12 9419 objects to objects.h 9420 [Steve Henson] 9421 9422 *) Add a new 'indent' option to some X509V3 extension code. Initial ASN1 9423 and display support for Thawte strong extranet extension. 9424 [Steve Henson] 9425 9426 *) Add LinuxPPC support. 9427 [Jeff Dubrule <igor@pobox.org>] 9428 9429 *) Get rid of redundant BN file bn_mulw.c, and rename bn_div64 to 9430 bn_div_words in alpha.s. 9431 [Hannes Reinecke <H.Reinecke@hw.ac.uk> and Ben Laurie] 9432 9433 *) Make sure the RSA OAEP test is skipped under -DRSAref because 9434 OAEP isn't supported when OpenSSL is built with RSAref. 9435 [Ulf Moeller <ulf@fitug.de>] 9436 9437 *) Move definitions of IS_SET/IS_SEQUENCE inside crypto/asn1/asn1.h 9438 so they no longer are missing under -DNOPROTO. 9439 [Soren S. Jorvang <soren@t.dk>] 9440 9441 9442 Changes between 0.9.1c and 0.9.2b [22 Mar 1999] 9443 9444 *) Make SSL_get_peer_cert_chain() work in servers. Unfortunately, it still 9445 doesn't work when the session is reused. Coming soon! 9446 [Ben Laurie] 9447 9448 *) Fix a security hole, that allows sessions to be reused in the wrong 9449 context thus bypassing client cert protection! All software that uses 9450 client certs and session caches in multiple contexts NEEDS PATCHING to 9451 allow session reuse! A fuller solution is in the works. 9452 [Ben Laurie, problem pointed out by Holger Reif, Bodo Moeller (and ???)] 9453 9454 *) Some more source tree cleanups (removed obsolete files 9455 crypto/bf/asm/bf586.pl, test/test.txt and crypto/sha/asm/f.s; changed 9456 permission on "config" script to be executable) and a fix for the INSTALL 9457 document. 9458 [Ulf Moeller <ulf@fitug.de>] 9459 9460 *) Remove some legacy and erroneous uses of malloc, free instead of 9461 Malloc, Free. 9462 [Lennart Bang <lob@netstream.se>, with minor changes by Steve] 9463 9464 *) Make rsa_oaep_test return non-zero on error. 9465 [Ulf Moeller <ulf@fitug.de>] 9466 9467 *) Add support for native Solaris shared libraries. Configure 9468 solaris-sparc-sc4-pic, make, then run shlib/solaris-sc4.sh. It'd be nice 9469 if someone would make that last step automatic. 9470 [Matthias Loepfe <Matthias.Loepfe@AdNovum.CH>] 9471 9472 *) ctx_size was not built with the right compiler during "make links". Fixed. 9473 [Ben Laurie] 9474 9475 *) Change the meaning of 'ALL' in the cipher list. It now means "everything 9476 except NULL ciphers". This means the default cipher list will no longer 9477 enable NULL ciphers. They need to be specifically enabled e.g. with 9478 the string "DEFAULT:eNULL". 9479 [Steve Henson] 9480 9481 *) Fix to RSA private encryption routines: if p < q then it would 9482 occasionally produce an invalid result. This will only happen with 9483 externally generated keys because OpenSSL (and SSLeay) ensure p > q. 9484 [Steve Henson] 9485 9486 *) Be less restrictive and allow also `perl util/perlpath.pl 9487 /path/to/bin/perl' in addition to `perl util/perlpath.pl /path/to/bin', 9488 because this way one can also use an interpreter named `perl5' (which is 9489 usually the name of Perl 5.xxx on platforms where an Perl 4.x is still 9490 installed as `perl'). 9491 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 9492 9493 *) Let util/clean-depend.pl work also with older Perl 5.00x versions. 9494 [Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 9495 9496 *) Fix Makefile.org so CC,CFLAG etc are passed to 'make links' add 9497 advapi32.lib to Win32 build and change the pem test comparision 9498 to fc.exe (thanks to Ulrich Kroener <kroneru@yahoo.com> for the 9499 suggestion). Fix misplaced ASNI prototypes and declarations in evp.h 9500 and crypto/des/ede_cbcm_enc.c. 9501 [Steve Henson] 9502 9503 *) DES quad checksum was broken on big-endian architectures. Fixed. 9504 [Ben Laurie] 9505 9506 *) Comment out two functions in bio.h that aren't implemented. Fix up the 9507 Win32 test batch file so it (might) work again. The Win32 test batch file 9508 is horrible: I feel ill.... 9509 [Steve Henson] 9510 9511 *) Move various #ifdefs around so NO_SYSLOG, NO_DIRENT etc are now selected 9512 in e_os.h. Audit of header files to check ANSI and non ANSI 9513 sections: 10 functions were absent from non ANSI section and not exported 9514 from Windows DLLs. Fixed up libeay.num for new functions. 9515 [Steve Henson] 9516 9517 *) Make `openssl version' output lines consistent. 9518 [Ralf S. Engelschall] 9519 9520 *) Fix Win32 symbol export lists for BIO functions: Added 9521 BIO_get_ex_new_index, BIO_get_ex_num, BIO_get_ex_data and BIO_set_ex_data 9522 to ms/libeay{16,32}.def. 9523 [Ralf S. Engelschall] 9524 9525 *) Second round of fixing the OpenSSL perl/ stuff. It now at least compiled 9526 fine under Unix and passes some trivial tests I've now added. But the 9527 whole stuff is horribly incomplete, so a README.1ST with a disclaimer was 9528 added to make sure no one expects that this stuff really works in the 9529 OpenSSL 0.9.2 release. Additionally I've started to clean the XS sources 9530 up and fixed a few little bugs and inconsistencies in OpenSSL.{pm,xs} and 9531 openssl_bio.xs. 9532 [Ralf S. Engelschall] 9533 9534 *) Fix the generation of two part addresses in perl. 9535 [Kenji Miyake <kenji@miyake.org>, integrated by Ben Laurie] 9536 9537 *) Add config entry for Linux on MIPS. 9538 [John Tobey <jtobey@channel1.com>] 9539 9540 *) Make links whenever Configure is run, unless we are on Windoze. 9541 [Ben Laurie] 9542 9543 *) Permit extensions to be added to CRLs using crl_section in openssl.cnf. 9544 Currently only issuerAltName and AuthorityKeyIdentifier make any sense 9545 in CRLs. 9546 [Steve Henson] 9547 9548 *) Add a useful kludge to allow package maintainers to specify compiler and 9549 other platforms details on the command line without having to patch the 9550 Configure script everytime: One now can use ``perl Configure 9551 <id>:<details>'', i.e. platform ids are allowed to have details appended 9552 to them (seperated by colons). This is treated as there would be a static 9553 pre-configured entry in Configure's %table under key <id> with value 9554 <details> and ``perl Configure <id>'' is called. So, when you want to 9555 perform a quick test-compile under FreeBSD 3.1 with pgcc and without 9556 assembler stuff you can use ``perl Configure "FreeBSD-elf:pgcc:-O6:::"'' 9557 now, which overrides the FreeBSD-elf entry on-the-fly. 9558 [Ralf S. Engelschall] 9559 9560 *) Disable new TLS1 ciphersuites by default: they aren't official yet. 9561 [Ben Laurie] 9562 9563 *) Allow DSO flags like -fpic, -fPIC, -KPIC etc. to be specified 9564 on the `perl Configure ...' command line. This way one can compile 9565 OpenSSL libraries with Position Independent Code (PIC) which is needed 9566 for linking it into DSOs. 9567 [Ralf S. Engelschall] 9568 9569 *) Remarkably, export ciphers were totally broken and no-one had noticed! 9570 Fixed. 9571 [Ben Laurie] 9572 9573 *) Cleaned up the LICENSE document: The official contact for any license 9574 questions now is the OpenSSL core team under openssl-core@openssl.org. 9575 And add a paragraph about the dual-license situation to make sure people 9576 recognize that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply 9577 to the OpenSSL toolkit. 9578 [Ralf S. Engelschall] 9579 9580 *) General source tree makefile cleanups: Made `making xxx in yyy...' 9581 display consistent in the source tree and replaced `/bin/rm' by `rm'. 9582 Additonally cleaned up the `make links' target: Remove unnecessary 9583 semicolons, subsequent redundant removes, inline point.sh into mklink.sh 9584 to speed processing and no longer clutter the display with confusing 9585 stuff. Instead only the actually done links are displayed. 9586 [Ralf S. Engelschall] 9587 9588 *) Permit null encryption ciphersuites, used for authentication only. It used 9589 to be necessary to set the preprocessor define SSL_ALLOW_ENULL to do this. 9590 It is now necessary to set SSL_FORBID_ENULL to prevent the use of null 9591 encryption. 9592 [Ben Laurie] 9593 9594 *) Add a bunch of fixes to the PKCS#7 stuff. It used to sometimes reorder 9595 signed attributes when verifying signatures (this would break them), 9596 the detached data encoding was wrong and public keys obtained using 9597 X509_get_pubkey() weren't freed. 9598 [Steve Henson] 9599 9600 *) Add text documentation for the BUFFER functions. Also added a work around 9601 to a Win95 console bug. This was triggered by the password read stuff: the 9602 last character typed gets carried over to the next fread(). If you were 9603 generating a new cert request using 'req' for example then the last 9604 character of the passphrase would be CR which would then enter the first 9605 field as blank. 9606 [Steve Henson] 9607 9608 *) Added the new `Includes OpenSSL Cryptography Software' button as 9609 doc/openssl_button.{gif,html} which is similar in style to the old SSLeay 9610 button and can be used by applications based on OpenSSL to show the 9611 relationship to the OpenSSL project. 9612 [Ralf S. Engelschall] 9613 9614 *) Remove confusing variables in function signatures in files 9615 ssl/ssl_lib.c and ssl/ssl.h. 9616 [Lennart Bong <lob@kulthea.stacken.kth.se>] 9617 9618 *) Don't install bss_file.c under PREFIX/include/ 9619 [Lennart Bong <lob@kulthea.stacken.kth.se>] 9620 9621 *) Get the Win32 compile working again. Modify mkdef.pl so it can handle 9622 functions that return function pointers and has support for NT specific 9623 stuff. Fix mk1mf.pl and VC-32.pl to support NT differences also. Various 9624 #ifdef WIN32 and WINNTs sprinkled about the place and some changes from 9625 unsigned to signed types: this was killing the Win32 compile. 9626 [Steve Henson] 9627 9628 *) Add new certificate file to stack functions, 9629 SSL_add_dir_cert_subjects_to_stack() and 9630 SSL_add_file_cert_subjects_to_stack(). These largely supplant 9631 SSL_load_client_CA_file(), and can be used to add multiple certs easily 9632 to a stack (usually this is then handed to SSL_CTX_set_client_CA_list()). 9633 This means that Apache-SSL and similar packages don't have to mess around 9634 to add as many CAs as they want to the preferred list. 9635 [Ben Laurie] 9636 9637 *) Experiment with doxygen documentation. Currently only partially applied to 9638 ssl/ssl_lib.c. 9639 See http://www.stack.nl/~dimitri/doxygen/index.html, and run doxygen with 9640 openssl.doxy as the configuration file. 9641 [Ben Laurie] 9642 9643 *) Get rid of remaining C++-style comments which strict C compilers hate. 9644 [Ralf S. Engelschall, pointed out by Carlos Amengual] 9645 9646 *) Changed BN_RECURSION in bn_mont.c to BN_RECURSION_MONT so it is not 9647 compiled in by default: it has problems with large keys. 9648 [Steve Henson] 9649 9650 *) Add a bunch of SSL_xxx() functions for configuring the temporary RSA and 9651 DH private keys and/or callback functions which directly correspond to 9652 their SSL_CTX_xxx() counterparts but work on a per-connection basis. This 9653 is needed for applications which have to configure certificates on a 9654 per-connection basis (e.g. Apache+mod_ssl) instead of a per-context basis 9655 (e.g. s_server). 9656 For the RSA certificate situation is makes no difference, but 9657 for the DSA certificate situation this fixes the "no shared cipher" 9658 problem where the OpenSSL cipher selection procedure failed because the 9659 temporary keys were not overtaken from the context and the API provided 9660 no way to reconfigure them. 9661 The new functions now let applications reconfigure the stuff and they 9662 are in detail: SSL_need_tmp_RSA, SSL_set_tmp_rsa, SSL_set_tmp_dh, 9663 SSL_set_tmp_rsa_callback and SSL_set_tmp_dh_callback. Additionally a new 9664 non-public-API function ssl_cert_instantiate() is used as a helper 9665 function and also to reduce code redundancy inside ssl_rsa.c. 9666 [Ralf S. Engelschall] 9667 9668 *) Move s_server -dcert and -dkey options out of the undocumented feature 9669 area because they are useful for the DSA situation and should be 9670 recognized by the users. 9671 [Ralf S. Engelschall] 9672 9673 *) Fix the cipher decision scheme for export ciphers: the export bits are 9674 *not* within SSL_MKEY_MASK or SSL_AUTH_MASK, they are within 9675 SSL_EXP_MASK. So, the original variable has to be used instead of the 9676 already masked variable. 9677 [Richard Levitte <levitte@stacken.kth.se>] 9678 9679 *) Fix 'port' variable from `int' to `unsigned int' in crypto/bio/b_sock.c 9680 [Richard Levitte <levitte@stacken.kth.se>] 9681 9682 *) Change type of another md_len variable in pk7_doit.c:PKCS7_dataFinal() 9683 from `int' to `unsigned int' because it's a length and initialized by 9684 EVP_DigestFinal() which expects an `unsigned int *'. 9685 [Richard Levitte <levitte@stacken.kth.se>] 9686 9687 *) Don't hard-code path to Perl interpreter on shebang line of Configure 9688 script. Instead use the usual Shell->Perl transition trick. 9689 [Ralf S. Engelschall] 9690 9691 *) Make `openssl x509 -noout -modulus' functional also for DSA certificates 9692 (in addition to RSA certificates) to match the behaviour of `openssl dsa 9693 -noout -modulus' as it's already the case for `openssl rsa -noout 9694 -modulus'. For RSA the -modulus is the real "modulus" while for DSA 9695 currently the public key is printed (a decision which was already done by 9696 `openssl dsa -modulus' in the past) which serves a similar purpose. 9697 Additionally the NO_RSA no longer completely removes the whole -modulus 9698 option; it now only avoids using the RSA stuff. Same applies to NO_DSA 9699 now, too. 9700 [Ralf S. Engelschall] 9701 9702 *) Add Arne Ansper's reliable BIO - this is an encrypted, block-digested 9703 BIO. See the source (crypto/evp/bio_ok.c) for more info. 9704 [Arne Ansper <arne@ats.cyber.ee>] 9705 9706 *) Dump the old yucky req code that tried (and failed) to allow raw OIDs 9707 to be added. Now both 'req' and 'ca' can use new objects defined in the 9708 config file. 9709 [Steve Henson] 9710 9711 *) Add cool BIO that does syslog (or event log on NT). 9712 [Arne Ansper <arne@ats.cyber.ee>, integrated by Ben Laurie] 9713 9714 *) Add support for new TLS ciphersuites, TLS_RSA_EXPORT56_WITH_RC4_56_MD5, 9715 TLS_RSA_EXPORT56_WITH_RC2_CBC_56_MD5 and 9716 TLS_RSA_EXPORT56_WITH_DES_CBC_SHA, as specified in "56-bit Export Cipher 9717 Suites For TLS", draft-ietf-tls-56-bit-ciphersuites-00.txt. 9718 [Ben Laurie] 9719 9720 *) Add preliminary config info for new extension code. 9721 [Steve Henson] 9722 9723 *) Make RSA_NO_PADDING really use no padding. 9724 [Ulf Moeller <ulf@fitug.de>] 9725 9726 *) Generate errors when private/public key check is done. 9727 [Ben Laurie] 9728 9729 *) Overhaul for 'crl' utility. New function X509_CRL_print. Partial support 9730 for some CRL extensions and new objects added. 9731 [Steve Henson] 9732 9733 *) Really fix the ASN1 IMPLICIT bug this time... Partial support for private 9734 key usage extension and fuller support for authority key id. 9735 [Steve Henson] 9736 9737 *) Add OAEP encryption for the OpenSSL crypto library. OAEP is the improved 9738 padding method for RSA, which is recommended for new applications in PKCS 9739 #1 v2.0 (RFC 2437, October 1998). 9740 OAEP (Optimal Asymmetric Encryption Padding) has better theoretical 9741 foundations than the ad-hoc padding used in PKCS #1 v1.5. It is secure 9742 against Bleichbacher's attack on RSA. 9743 [Ulf Moeller <ulf@fitug.de>, reformatted, corrected and integrated by 9744 Ben Laurie] 9745 9746 *) Updates to the new SSL compression code 9747 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 9748 9749 *) Fix so that the version number in the master secret, when passed 9750 via RSA, checks that if TLS was proposed, but we roll back to SSLv3 9751 (because the server will not accept higher), that the version number 9752 is 0x03,0x01, not 0x03,0x00 9753 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 9754 9755 *) Run extensive memory leak checks on SSL apps. Fixed *lots* of memory 9756 leaks in ssl/ relating to new X509_get_pubkey() behaviour. Also fixes 9757 in apps/ and an unrelated leak in crypto/dsa/dsa_vrf.c 9758 [Steve Henson] 9759 9760 *) Support for RAW extensions where an arbitrary extension can be 9761 created by including its DER encoding. See apps/openssl.cnf for 9762 an example. 9763 [Steve Henson] 9764 9765 *) Make sure latest Perl versions don't interpret some generated C array 9766 code as Perl array code in the crypto/err/err_genc.pl script. 9767 [Lars Weber <3weber@informatik.uni-hamburg.de>] 9768 9769 *) Modify ms/do_ms.bat to not generate assembly language makefiles since 9770 not many people have the assembler. Various Win32 compilation fixes and 9771 update to the INSTALL.W32 file with (hopefully) more accurate Win32 9772 build instructions. 9773 [Steve Henson] 9774 9775 *) Modify configure script 'Configure' to automatically create crypto/date.h 9776 file under Win32 and also build pem.h from pem.org. New script 9777 util/mkfiles.pl to create the MINFO file on environments that can't do a 9778 'make files': perl util/mkfiles.pl >MINFO should work. 9779 [Steve Henson] 9780 9781 *) Major rework of DES function declarations, in the pursuit of correctness 9782 and purity. As a result, many evil casts evaporated, and some weirdness, 9783 too. You may find this causes warnings in your code. Zapping your evil 9784 casts will probably fix them. Mostly. 9785 [Ben Laurie] 9786 9787 *) Fix for a typo in asn1.h. Bug fix to object creation script 9788 obj_dat.pl. It considered a zero in an object definition to mean 9789 "end of object": none of the objects in objects.h have any zeros 9790 so it wasn't spotted. 9791 [Steve Henson, reported by Erwann ABALEA <eabalea@certplus.com>] 9792 9793 *) Add support for Triple DES Cipher Block Chaining with Output Feedback 9794 Masking (CBCM). In the absence of test vectors, the best I have been able 9795 to do is check that the decrypt undoes the encrypt, so far. Send me test 9796 vectors if you have them. 9797 [Ben Laurie] 9798 9799 *) Correct calculation of key length for export ciphers (too much space was 9800 allocated for null ciphers). This has not been tested! 9801 [Ben Laurie] 9802 9803 *) Modifications to the mkdef.pl for Win32 DEF file creation. The usage 9804 message is now correct (it understands "crypto" and "ssl" on its 9805 command line). There is also now an "update" option. This will update 9806 the util/ssleay.num and util/libeay.num files with any new functions. 9807 If you do a: 9808 perl util/mkdef.pl crypto ssl update 9809 it will update them. 9810 [Steve Henson] 9811 9812 *) Overhauled the Perl interface (perl/*): 9813 - ported BN stuff to OpenSSL's different BN library 9814 - made the perl/ source tree CVS-aware 9815 - renamed the package from SSLeay to OpenSSL (the files still contain 9816 their history because I've copied them in the repository) 9817 - removed obsolete files (the test scripts will be replaced 9818 by better Test::Harness variants in the future) 9819 [Ralf S. Engelschall] 9820 9821 *) First cut for a very conservative source tree cleanup: 9822 1. merge various obsolete readme texts into doc/ssleay.txt 9823 where we collect the old documents and readme texts. 9824 2. remove the first part of files where I'm already sure that we no 9825 longer need them because of three reasons: either they are just temporary 9826 files which were left by Eric or they are preserved original files where 9827 I've verified that the diff is also available in the CVS via "cvs diff 9828 -rSSLeay_0_8_1b" or they were renamed (as it was definitely the case for 9829 the crypto/md/ stuff). 9830 [Ralf S. Engelschall] 9831 9832 *) More extension code. Incomplete support for subject and issuer alt 9833 name, issuer and authority key id. Change the i2v function parameters 9834 and add an extra 'crl' parameter in the X509V3_CTX structure: guess 9835 what that's for :-) Fix to ASN1 macro which messed up 9836 IMPLICIT tag and add f_enum.c which adds a2i, i2a for ENUMERATED. 9837 [Steve Henson] 9838 9839 *) Preliminary support for ENUMERATED type. This is largely copied from the 9840 INTEGER code. 9841 [Steve Henson] 9842 9843 *) Add new function, EVP_MD_CTX_copy() to replace frequent use of memcpy. 9844 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 9845 9846 *) Make sure `make rehash' target really finds the `openssl' program. 9847 [Ralf S. Engelschall, Matthias Loepfe <Matthias.Loepfe@adnovum.ch>] 9848 9849 *) Squeeze another 7% of speed out of MD5 assembler, at least on a P2. I'd 9850 like to hear about it if this slows down other processors. 9851 [Ben Laurie] 9852 9853 *) Add CygWin32 platform information to Configure script. 9854 [Alan Batie <batie@aahz.jf.intel.com>] 9855 9856 *) Fixed ms/32all.bat script: `no_asm' -> `no-asm' 9857 [Rainer W. Gerling <gerling@mpg-gv.mpg.de>] 9858 9859 *) New program nseq to manipulate netscape certificate sequences 9860 [Steve Henson] 9861 9862 *) Modify crl2pkcs7 so it supports multiple -certfile arguments. Fix a 9863 few typos. 9864 [Steve Henson] 9865 9866 *) Fixes to BN code. Previously the default was to define BN_RECURSION 9867 but the BN code had some problems that would cause failures when 9868 doing certificate verification and some other functions. 9869 [Eric A. Young, (from changes to C2Net SSLeay, integrated by Mark Cox)] 9870 9871 *) Add ASN1 and PEM code to support netscape certificate sequences. 9872 [Steve Henson] 9873 9874 *) Add ASN1 and PEM code to support netscape certificate sequences. 9875 [Steve Henson] 9876 9877 *) Add several PKIX and private extended key usage OIDs. 9878 [Steve Henson] 9879 9880 *) Modify the 'ca' program to handle the new extension code. Modify 9881 openssl.cnf for new extension format, add comments. 9882 [Steve Henson] 9883 9884 *) More X509 V3 changes. Fix typo in v3_bitstr.c. Add support to 'req' 9885 and add a sample to openssl.cnf so req -x509 now adds appropriate 9886 CA extensions. 9887 [Steve Henson] 9888 9889 *) Continued X509 V3 changes. Add to other makefiles, integrate with the 9890 error code, add initial support to X509_print() and x509 application. 9891 [Steve Henson] 9892 9893 *) Takes a deep breath and start addding X509 V3 extension support code. Add 9894 files in crypto/x509v3. Move original stuff to crypto/x509v3/old. All this 9895 stuff is currently isolated and isn't even compiled yet. 9896 [Steve Henson] 9897 9898 *) Continuing patches for GeneralizedTime. Fix up certificate and CRL 9899 ASN1 to use ASN1_TIME and modify print routines to use ASN1_TIME_print. 9900 Removed the versions check from X509 routines when loading extensions: 9901 this allows certain broken certificates that don't set the version 9902 properly to be processed. 9903 [Steve Henson] 9904 9905 *) Deal with irritating shit to do with dependencies, in YAAHW (Yet Another 9906 Ad Hoc Way) - Makefile.ssls now all contain local dependencies, which 9907 can still be regenerated with "make depend". 9908 [Ben Laurie] 9909 9910 *) Spelling mistake in C version of CAST-128. 9911 [Ben Laurie, reported by Jeremy Hylton <jeremy@cnri.reston.va.us>] 9912 9913 *) Changes to the error generation code. The perl script err-code.pl 9914 now reads in the old error codes and retains the old numbers, only 9915 adding new ones if necessary. It also only changes the .err files if new 9916 codes are added. The makefiles have been modified to only insert errors 9917 when needed (to avoid needlessly modifying header files). This is done 9918 by only inserting errors if the .err file is newer than the auto generated 9919 C file. To rebuild all the error codes from scratch (the old behaviour) 9920 either modify crypto/Makefile.ssl to pass the -regen flag to err_code.pl 9921 or delete all the .err files. 9922 [Steve Henson] 9923 9924 *) CAST-128 was incorrectly implemented for short keys. The C version has 9925 been fixed, but is untested. The assembler versions are also fixed, but 9926 new assembler HAS NOT BEEN GENERATED FOR WIN32 - the Makefile needs fixing 9927 to regenerate it if needed. 9928 [Ben Laurie, reported (with fix for C version) by Jun-ichiro itojun 9929 Hagino <itojun@kame.net>] 9930 9931 *) File was opened incorrectly in randfile.c. 9932 [Ulf M�ller <ulf@fitug.de>] 9933 9934 *) Beginning of support for GeneralizedTime. d2i, i2d, check and print 9935 functions. Also ASN1_TIME suite which is a CHOICE of UTCTime or 9936 GeneralizedTime. ASN1_TIME is the proper type used in certificates et 9937 al: it's just almost always a UTCTime. Note this patch adds new error 9938 codes so do a "make errors" if there are problems. 9939 [Steve Henson] 9940 9941 *) Correct Linux 1 recognition in config. 9942 [Ulf M�ller <ulf@fitug.de>] 9943 9944 *) Remove pointless MD5 hash when using DSA keys in ca. 9945 [Anonymous <nobody@replay.com>] 9946 9947 *) Generate an error if given an empty string as a cert directory. Also 9948 generate an error if handed NULL (previously returned 0 to indicate an 9949 error, but didn't set one). 9950 [Ben Laurie, reported by Anonymous <nobody@replay.com>] 9951 9952 *) Add prototypes to SSL methods. Make SSL_write's buffer const, at last. 9953 [Ben Laurie] 9954 9955 *) Fix the dummy function BN_ref_mod_exp() in rsaref.c to have the correct 9956 parameters. This was causing a warning which killed off the Win32 compile. 9957 [Steve Henson] 9958 9959 *) Remove C++ style comments from crypto/bn/bn_local.h. 9960 [Neil Costigan <neil.costigan@celocom.com>] 9961 9962 *) The function OBJ_txt2nid was broken. It was supposed to return a nid 9963 based on a text string, looking up short and long names and finally 9964 "dot" format. The "dot" format stuff didn't work. Added new function 9965 OBJ_txt2obj to do the same but return an ASN1_OBJECT and rewrote 9966 OBJ_txt2nid to use it. OBJ_txt2obj can also return objects even if the 9967 OID is not part of the table. 9968 [Steve Henson] 9969 9970 *) Add prototypes to X509 lookup/verify methods, fixing a bug in 9971 X509_LOOKUP_by_alias(). 9972 [Ben Laurie] 9973 9974 *) Sort openssl functions by name. 9975 [Ben Laurie] 9976 9977 *) Get the gendsa program working (hopefully) and add it to app list. Remove 9978 encryption from sample DSA keys (in case anyone is interested the password 9979 was "1234"). 9980 [Steve Henson] 9981 9982 *) Make _all_ *_free functions accept a NULL pointer. 9983 [Frans Heymans <fheymans@isaserver.be>] 9984 9985 *) If a DH key is generated in s3_srvr.c, don't blow it by trying to use 9986 NULL pointers. 9987 [Anonymous <nobody@replay.com>] 9988 9989 *) s_server should send the CAfile as acceptable CAs, not its own cert. 9990 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] 9991 9992 *) Don't blow it for numeric -newkey arguments to apps/req. 9993 [Bodo Moeller <3moeller@informatik.uni-hamburg.de>] 9994 9995 *) Temp key "for export" tests were wrong in s3_srvr.c. 9996 [Anonymous <nobody@replay.com>] 9997 9998 *) Add prototype for temp key callback functions 9999 SSL_CTX_set_tmp_{rsa,dh}_callback(). 10000 [Ben Laurie] 10001 10002 *) Make DH_free() tolerate being passed a NULL pointer (like RSA_free() and 10003 DSA_free()). Make X509_PUBKEY_set() check for errors in d2i_PublicKey(). 10004 [Steve Henson] 10005 10006 *) X509_name_add_entry() freed the wrong thing after an error. 10007 [Arne Ansper <arne@ats.cyber.ee>] 10008 10009 *) rsa_eay.c would attempt to free a NULL context. 10010 [Arne Ansper <arne@ats.cyber.ee>] 10011 10012 *) BIO_s_socket() had a broken should_retry() on Windoze. 10013 [Arne Ansper <arne@ats.cyber.ee>] 10014 10015 *) BIO_f_buffer() didn't pass on BIO_CTRL_FLUSH. 10016 [Arne Ansper <arne@ats.cyber.ee>] 10017 10018 *) Make sure the already existing X509_STORE->depth variable is initialized 10019 in X509_STORE_new(), but document the fact that this variable is still 10020 unused in the certificate verification process. 10021 [Ralf S. Engelschall] 10022 10023 *) Fix the various library and apps files to free up pkeys obtained from 10024 X509_PUBKEY_get() et al. Also allow x509.c to handle netscape extensions. 10025 [Steve Henson] 10026 10027 *) Fix reference counting in X509_PUBKEY_get(). This makes 10028 demos/maurice/example2.c work, amongst others, probably. 10029 [Steve Henson and Ben Laurie] 10030 10031 *) First cut of a cleanup for apps/. First the `ssleay' program is now named 10032 `openssl' and second, the shortcut symlinks for the `openssl <command>' 10033 are no longer created. This way we have a single and consistent command 10034 line interface `openssl <command>', similar to `cvs <command>'. 10035 [Ralf S. Engelschall, Paul Sutton and Ben Laurie] 10036 10037 *) ca.c: move test for DSA keys inside #ifndef NO_DSA. Make pubkey 10038 BIT STRING wrapper always have zero unused bits. 10039 [Steve Henson] 10040 10041 *) Add CA.pl, perl version of CA.sh, add extended key usage OID. 10042 [Steve Henson] 10043 10044 *) Make the top-level INSTALL documentation easier to understand. 10045 [Paul Sutton] 10046 10047 *) Makefiles updated to exit if an error occurs in a sub-directory 10048 make (including if user presses ^C) [Paul Sutton] 10049 10050 *) Make Montgomery context stuff explicit in RSA data structure. 10051 [Ben Laurie] 10052 10053 *) Fix build order of pem and err to allow for generated pem.h. 10054 [Ben Laurie] 10055 10056 *) Fix renumbering bug in X509_NAME_delete_entry(). 10057 [Ben Laurie] 10058 10059 *) Enhanced the err-ins.pl script so it makes the error library number 10060 global and can add a library name. This is needed for external ASN1 and 10061 other error libraries. 10062 [Steve Henson] 10063 10064 *) Fixed sk_insert which never worked properly. 10065 [Steve Henson] 10066 10067 *) Fix ASN1 macros so they can handle indefinite length construted 10068 EXPLICIT tags. Some non standard certificates use these: they can now 10069 be read in. 10070 [Steve Henson] 10071 10072 *) Merged the various old/obsolete SSLeay documentation files (doc/xxx.doc) 10073 into a single doc/ssleay.txt bundle. This way the information is still 10074 preserved but no longer messes up this directory. Now it's new room for 10075 the new set of documenation files. 10076 [Ralf S. Engelschall] 10077 10078 *) SETs were incorrectly DER encoded. This was a major pain, because they 10079 shared code with SEQUENCEs, which aren't coded the same. This means that 10080 almost everything to do with SETs or SEQUENCEs has either changed name or 10081 number of arguments. 10082 [Ben Laurie, based on a partial fix by GP Jayan <gp@nsj.co.jp>] 10083 10084 *) Fix test data to work with the above. 10085 [Ben Laurie] 10086 10087 *) Fix the RSA header declarations that hid a bug I fixed in 0.9.0b but 10088 was already fixed by Eric for 0.9.1 it seems. 10089 [Ben Laurie - pointed out by Ulf M�ller <ulf@fitug.de>] 10090 10091 *) Autodetect FreeBSD3. 10092 [Ben Laurie] 10093 10094 *) Fix various bugs in Configure. This affects the following platforms: 10095 nextstep 10096 ncr-scde 10097 unixware-2.0 10098 unixware-2.0-pentium 10099 sco5-cc. 10100 [Ben Laurie] 10101 10102 *) Eliminate generated files from CVS. Reorder tests to regenerate files 10103 before they are needed. 10104 [Ben Laurie] 10105 10106 *) Generate Makefile.ssl from Makefile.org (to keep CVS happy). 10107 [Ben Laurie] 10108 10109 10110 Changes between 0.9.1b and 0.9.1c [23-Dec-1998] 10111 10112 *) Added OPENSSL_VERSION_NUMBER to crypto/crypto.h and 10113 changed SSLeay to OpenSSL in version strings. 10114 [Ralf S. Engelschall] 10115 10116 *) Some fixups to the top-level documents. 10117 [Paul Sutton] 10118 10119 *) Fixed the nasty bug where rsaref.h was not found under compile-time 10120 because the symlink to include/ was missing. 10121 [Ralf S. Engelschall] 10122 10123 *) Incorporated the popular no-RSA/DSA-only patches 10124 which allow to compile a RSA-free SSLeay. 10125 [Andrew Cooke / Interrader Ldt., Ralf S. Engelschall] 10126 10127 *) Fixed nasty rehash problem under `make -f Makefile.ssl links' 10128 when "ssleay" is still not found. 10129 [Ralf S. Engelschall] 10130 10131 *) Added more platforms to Configure: Cray T3E, HPUX 11, 10132 [Ralf S. Engelschall, Beckmann <beckman@acl.lanl.gov>] 10133 10134 *) Updated the README file. 10135 [Ralf S. Engelschall] 10136 10137 *) Added various .cvsignore files in the CVS repository subdirs 10138 to make a "cvs update" really silent. 10139 [Ralf S. Engelschall] 10140 10141 *) Recompiled the error-definition header files and added 10142 missing symbols to the Win32 linker tables. 10143 [Ralf S. Engelschall] 10144 10145 *) Cleaned up the top-level documents; 10146 o new files: CHANGES and LICENSE 10147 o merged VERSION, HISTORY* and README* files a CHANGES.SSLeay 10148 o merged COPYRIGHT into LICENSE 10149 o removed obsolete TODO file 10150 o renamed MICROSOFT to INSTALL.W32 10151 [Ralf S. Engelschall] 10152 10153 *) Removed dummy files from the 0.9.1b source tree: 10154 crypto/asn1/x crypto/bio/cd crypto/bio/fg crypto/bio/grep crypto/bio/vi 10155 crypto/bn/asm/......add.c crypto/bn/asm/a.out crypto/dsa/f crypto/md5/f 10156 crypto/pem/gmon.out crypto/perlasm/f crypto/pkcs7/build crypto/rsa/f 10157 crypto/sha/asm/f crypto/threads/f ms/zzz ssl/f ssl/f.mak test/f 10158 util/f.mak util/pl/f util/pl/f.mak crypto/bf/bf_locl.old apps/f 10159 [Ralf S. Engelschall] 10160 10161 *) Added various platform portability fixes. 10162 [Mark J. Cox] 10163 10164 *) The Genesis of the OpenSSL rpject: 10165 We start with the latest (unreleased) SSLeay version 0.9.1b which Eric A. 10166 Young and Tim J. Hudson created while they were working for C2Net until 10167 summer 1998. 10168 [The OpenSSL Project] 10169 10170 10171 Changes between 0.9.0b and 0.9.1b [not released] 10172 10173 *) Updated a few CA certificates under certs/ 10174 [Eric A. Young] 10175 10176 *) Changed some BIGNUM api stuff. 10177 [Eric A. Young] 10178 10179 *) Various platform ports: OpenBSD, Ultrix, IRIX 64bit, NetBSD, 10180 DGUX x86, Linux Alpha, etc. 10181 [Eric A. Young] 10182 10183 *) New COMP library [crypto/comp/] for SSL Record Layer Compression: 10184 RLE (dummy implemented) and ZLIB (really implemented when ZLIB is 10185 available). 10186 [Eric A. Young] 10187 10188 *) Add -strparse option to asn1pars program which parses nested 10189 binary structures 10190 [Dr Stephen Henson <shenson@bigfoot.com>] 10191 10192 *) Added "oid_file" to ssleay.cnf for "ca" and "req" programs. 10193 [Eric A. Young] 10194 10195 *) DSA fix for "ca" program. 10196 [Eric A. Young] 10197 10198 *) Added "-genkey" option to "dsaparam" program. 10199 [Eric A. Young] 10200 10201 *) Added RIPE MD160 (rmd160) message digest. 10202 [Eric A. Young] 10203 10204 *) Added -a (all) option to "ssleay version" command. 10205 [Eric A. Young] 10206 10207 *) Added PLATFORM define which is the id given to Configure. 10208 [Eric A. Young] 10209 10210 *) Added MemCheck_XXXX functions to crypto/mem.c for memory checking. 10211 [Eric A. Young] 10212 10213 *) Extended the ASN.1 parser routines. 10214 [Eric A. Young] 10215 10216 *) Extended BIO routines to support REUSEADDR, seek, tell, etc. 10217 [Eric A. Young] 10218 10219 *) Added a BN_CTX to the BN library. 10220 [Eric A. Young] 10221 10222 *) Fixed the weak key values in DES library 10223 [Eric A. Young] 10224 10225 *) Changed API in EVP library for cipher aliases. 10226 [Eric A. Young] 10227 10228 *) Added support for RC2/64bit cipher. 10229 [Eric A. Young] 10230 10231 *) Converted the lhash library to the crypto/mem.c functions. 10232 [Eric A. Young] 10233 10234 *) Added more recognized ASN.1 object ids. 10235 [Eric A. Young] 10236 10237 *) Added more RSA padding checks for SSL/TLS. 10238 [Eric A. Young] 10239 10240 *) Added BIO proxy/filter functionality. 10241 [Eric A. Young] 10242 10243 *) Added extra_certs to SSL_CTX which can be used 10244 send extra CA certificates to the client in the CA cert chain sending 10245 process. It can be configured with SSL_CTX_add_extra_chain_cert(). 10246 [Eric A. Young] 10247 10248 *) Now Fortezza is denied in the authentication phase because 10249 this is key exchange mechanism is not supported by SSLeay at all. 10250 [Eric A. Young] 10251 10252 *) Additional PKCS1 checks. 10253 [Eric A. Young] 10254 10255 *) Support the string "TLSv1" for all TLS v1 ciphers. 10256 [Eric A. Young] 10257 10258 *) Added function SSL_get_ex_data_X509_STORE_CTX_idx() which gives the 10259 ex_data index of the SSL context in the X509_STORE_CTX ex_data. 10260 [Eric A. Young] 10261 10262 *) Fixed a few memory leaks. 10263 [Eric A. Young] 10264 10265 *) Fixed various code and comment typos. 10266 [Eric A. Young] 10267 10268 *) A minor bug in ssl/s3_clnt.c where there would always be 4 0 10269 bytes sent in the client random. 10270 [Edward Bishop <ebishop@spyglass.com>] 10271 10272
