Do not use record version number > TLS 1.0 in initial client + hello: some (but not all) hanging servers will now work. + 2. If we set OPENSSL_MAX_TLS1_2_CIPHER_LENGTH this will truncate + the number of ciphers sent in the client hello. This should be + set to an even number, such as 50, for example by passing: + -DOPENSSL_MAX_TLS1_2_CIPHER_LENGTH=50 to config or Configure. + Most broken servers should now work. + 3. If all else fails setting OPENSSL_NO_TLS1_2_CLIENT will disable + TLS 1.2 client support entirely. + [Steve Henson] + + *) Fix SEGV in Vector Permutation AES module observed in OpenSSH. + [Andy Polyakov] + + Changes between 1.0.0h and 1.0.1 [14 Mar 2012] + + *) Add compatibility with old MDC2 signatures which use an ASN1 OCTET + STRING form instead of a DigestInfo. + [Steve Henson] + + *) The format used for MDC2 RSA signatures is inconsistent between EVP + and the RSA_sign/RSA_verify functions. This was made more apparent when + OpenSSL used RSA_sign/RSA_verify for some RSA signatures in particular + those which went through EVP_PKEY_METHOD in 1.0.0 and later. Detect + the correct format in RSA_verify so both forms transparently work. + [Steve Henson] + + *) Some servers which support TLS 1.0 can choke if we initially indicate + support for TLS 1.2 and later renegotiate using TLS 1.0 in the RSA + encrypted premaster secret. As a workaround use the maximum pemitted + client version in client hello, this should keep such servers happy + and still work with previous versions of OpenSSL. + [Steve Henson] + + *) Add support for TLS/DTLS heartbeats. + [Robin Seggelmann <seggelmann@fh-muenster.de>] + + *) Add support for SCTP. + [Robin Seggelmann <seggelmann@fh-muenster.de>] + + *) Improved PRNG seeding for VOS. + [Paul Green <Paul.Green@stratus.com>] + + *) Extensive assembler packs updates, most notably: + + - x86[_64]: AES-NI, PCLMULQDQ, RDRAND support; + - x86[_64]: SSSE3 support (SHA1, vector-permutation AES); + - x86_64: bit-sliced AES implementation; + - ARM: NEON support, contemporary platforms optimizations; + - s390x: z196 support; + - *: GHASH and GF(2^m) multiplication implementations; + + [Andy Polyakov] + + *) Make TLS-SRP code conformant with RFC 5054 API cleanup + (removal of unnecessary code) + [Peter Sylvester <peter.sylvester@edelweb.fr>] + + *) Add TLS key material exporter from RFC 5705. + [Eric Rescorla] + + *) Add DTLS-SRTP negotiation from RFC 5764. + [Eric Rescorla] + + *) Add Next Protocol Negotiation, + http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00.

Additional + signature parameters can be passed using this option and in + particular PSS. + [Steve Henson] + + *) Add RSA PSS signing function. This will generate and set the + appropriate AlgorithmIdentifiers for PSS based on those in the + corresponding EVP_MD_CTX structure. No application support yet. + [Steve Henson] + + *) Support for companion algorithm specific ASN1 signing routines. + New function ASN1_item_sign_ctx() signs a pre-initialised + EVP_MD_CTX structure and sets AlgorithmIdentifiers based on + the appropriate parameters. + [Steve Henson] + + *) Add new algorithm specific ASN1 verification initialisation function + to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1 + handling will be the same no matter what EVP_PKEY_METHOD is used. + Add a PSS handler to support verification of PSS signatures: checked + against a number of sample certificates. + [Steve Henson] + + *) Add signature printing for PSS. Add PSS OIDs. + [Steve Henson, Martin Kaiser <lists@kaiser.cx>] + + *) Add algorithm specific signature printing. An individual ASN1 method + can now print out signatures instead of the standard hex dump. + + More complex signatures (e.g. PSS) can print out more meaningful + information. Include DSA version that prints out the signature + parameters r, s. + [Steve Henson] + + *) Password based recipient info support for CMS library: implementing + RFC3211. + [Steve Henson] + + *) Split password based encryption into PBES2 and PBKDF2 functions. This + neatly separates the code into cipher and PBE sections and is required + for some algorithms that split PBES2 into separate pieces (such as + password based CMS). + [Steve Henson] + + *) Session-handling fixes: + - Fix handling of connections that are resuming with a session ID, + but also support Session Tickets. + - Fix a bug that suppressed issuing of a new ticket if the client + presented a ticket with an expired session. + - Try to set the ticket lifetime hint to something reasonable. + - Make tickets shorter by excluding irrelevant information. + - On the client side, don't ignore renewed tickets. + [Adam Langley, Bodo Moeller (Google)] + + *) Fix PSK session representation. + [Bodo Moeller] + + *) Add RC4-MD5 and AESNI-SHA1 "stitched" implementations. + + This work was sponsored by Intel. + [Andy Polyakov] + + *) Add GCM support to TLS library. Some custom code is needed to split + the IV between the fixed (from PRF) and explicit (from TLS record) + portions. This adds all GCM ciphersuites supported by RFC5288 and + RFC5289. Generalise some AES* cipherstrings to inlclude GCM and + add a special AESGCM string for GCM only. + [Steve Henson] + + *) Expand range of ctrls for AES GCM. Permit setting invocation + field on decrypt and retrieval of invocation field only on encrypt. + [Steve Henson] + + *) Add HMAC ECC ciphersuites from RFC5289. Include SHA384 PRF support. + As required by RFC5289 these ciphersuites cannot be used if for + versions of TLS earlier than 1.2. + [Steve Henson] + + *) For FIPS capable OpenSSL interpret a NULL default public key method + as unset and return the appopriate default but do *not* set the default. + This means we can return the appopriate method in applications that + swicth between FIPS and non-FIPS modes. + [Steve Henson] + + *) Redirect HMAC and CMAC operations to FIPS module in FIPS mode. If an + ENGINE is used then we cannot handle that in the FIPS module so we + keep original code iff non-FIPS operations are allowed. + [Steve Henson] + + *) Add -attime option to openssl utilities. + [Peter Eckersley <pde@eff.org>, Ben Laurie and Steve Henson] + + *) Redirect DSA and DH operations to FIPS module in FIPS mode. + [Steve Henson] + + *) Redirect ECDSA and ECDH operations to FIPS module in FIPS mode. Also use + FIPS EC methods unconditionally for now. + [Steve Henson] + + *) New build option no-ec2m to disable characteristic 2 code. + [Steve Henson] + + *) Backport libcrypto audit of return value checking from 1.1.0-dev; not + all cases can be covered as some introduce binary incompatibilities. + [Steve Henson] + + *) Redirect RSA operations to FIPS module including keygen, + encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods. + [Steve Henson] + + *) Add similar low level API blocking to ciphers. + [Steve Henson] + + *) Low level digest APIs are not approved in FIPS mode: any attempt + to use these will cause a fatal error. Applications that *really* want + to use them can use the private_* version instead. + [Steve Henson] + + *) Redirect cipher operations to FIPS module for FIPS builds. + [Steve Henson] + + *) Redirect digest operations to FIPS module for FIPS builds. + [Steve Henson] + + *) Update build system to add "fips" flag which will link in fipscanister.o + for static and shared library builds embedding a signature if needed. + [Steve Henson] + + *) Output TLS supported curves in preference order instead of numerical + order. This is currently hardcoded for the highest order curves first. + This should be configurable so applications can judge speed vs strength. + [Steve Henson] + + *) Add TLS v1.2 server support for client authentication. + [Steve Henson] + + *) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers + and enable MD5. + [Steve Henson] + + *) Functions FIPS_mode_set() and FIPS_mode() which call the underlying + FIPS modules versions. + [Steve Henson] + + *) Add TLS v1.2 client side support for client authentication. Keep cache + of handshake records longer as we don't know the hash algorithm to use + until after the certificate request message is received. + [Steve Henson] + + *) Initial TLS v1.2 client support. Add a default signature algorithms + extension including all the algorithms we support. Parse new signature + format in client key exchange. Relax some ECC signing restrictions for + TLS v1.2 as indicated in RFC5246. + [Steve Henson] + + *) Add server support for TLS v1.2 signature algorithms extension. Switch + to new signature format when needed using client digest preference. + All server ciphersuites should now work correctly in TLS v1.2. No client + support yet and no support for client certificates. + [Steve Henson] + + *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch + to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based + ciphersuites. At present only RSA key exchange ciphersuites work with + TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete + SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods + and version checking. + [Steve Henson] + + *) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled + with this defined it will not be affected by any changes to ssl internal + structures. Add several utility functions to allow openssl application + to work with OPENSSL_NO_SSL_INTERN defined. + [Steve Henson] + + *) Add SRP support. + [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie] + + *) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id. + [Steve Henson] + + *) Permit abbreviated handshakes when renegotiating using the function + SSL_renegotiate_abbreviated(). + [Robin Seggelmann <seggelmann@fh-muenster.de>] + + *) Add call to ENGINE_register_all_complete() to + ENGINE_load_builtin_engines(), so some implementations get used + automatically instead of needing explicit application support. + [Steve Henson] + + *) Add support for TLS key exporter as described in RFC5705. + [Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson] + + *) Initial TLSv1.1 support. Since TLSv1.1 is very similar to TLS v1.0 only + a few changes are required: + + Add SSL_OP_NO_TLSv1_1 flag. + Add TLSv1_1 methods. + Update version checking logic to handle version 1.1. + Add explicit IV handling (ported from DTLS code). + Add command line options to s_client/s_server. + [Steve Henson] + + Changes between 1.0.0g and 1.0.0h [12 Mar 2012] *) Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness in CMS and PKCS7 code.

Reorganise CRL processing + code and add additional score elements. Validate alternate CRL paths + as part of the CRL checking and indicate a new error "CRL path validation + error" in this case. Applications wanting additional details can use + the verify callback and check the new "parent" field. If this is not + NULL CRL path validation is taking place.

DN, email, DNS + and URI types are currently supported. + + This work was sponsored by Google. + [Steve Henson] + + *) To cater for systems that provide a pointer-based thread ID rather + than numeric, deprecate the current numeric thread ID mechanism and + replace it with a structure and associated callback type. This + mechanism allows a numeric "hash" to be extracted from a thread ID in + either case, and on platforms where pointers are larger than 'long', + mixing is done to help ensure the numeric 'hash' is usable even if it + can't be guaranteed unique. The default mechanism is to use "&errno" + as a pointer-based thread ID to distinguish between threads. + + Applications that want to provide their own thread IDs should now use + CRYPTO_THREADID_set_callback() to register a callback that will call + either CRYPTO_THREADID_set_numeric() or CRYPTO_THREADID_set_pointer(). + + Note that ERR_remove_state() is now deprecated, because it is tied + to the assumption that thread IDs are numeric. ERR_remove_state(0) + to free the current thread's error state should be replaced by + ERR_remove_thread_state(NULL). + + (This new approach replaces the functions CRYPTO_set_idptr_callback(), + CRYPTO_get_idptr_callback(), and CRYPTO_thread_idptr() that existed in + OpenSSL 0.9.9-dev between June 2006 and August 2008. Also, if an + application was previously providing a numeric thread callback that + was inappropriate for distinguishing threads, then uniqueness might + have been obtained with &errno that happened immediately in the + intermediate development versions of OpenSSL; this is no longer the + case, the numeric thread callback will now override the automatic use + of &errno.) + [Geoff Thorpe, with help from Bodo Moeller] + + *) Initial support for different CRL issuing certificates. This covers a + simple case where the self issued certificates in the chain exist and + the real CRL issuer is higher in the existing chain. + + This work was sponsored by Google. + [Steve Henson] + + *) Removed effectively defunct crypto/store from the build. + [Ben Laurie] + + *) Revamp of STACK to provide stronger type-checking. Still to come: + TXT_DB, bsearch(?), OBJ_bsearch, qsort, CRYPTO_EX_DATA, ASN1_VALUE, + ASN1_STRING, CONF_VALUE. + [Ben Laurie] + + *) Add a new SSL_MODE_RELEASE_BUFFERS mode flag to release unused buffer + RAM on SSL connections. This option can save about 34k per idle SSL. + [Nick Mathewson] + + *) Revamp of LHASH to provide stronger type-checking. Still to come: + STACK, TXT_DB, bsearch, qsort. + [Ben Laurie] + + *) Initial support for Cryptographic Message Syntax (aka CMS) based + on RFC3850, RFC3851 and RFC3852. New cms directory and cms utility, + support for data, signedData, compressedData, digestedData and + encryptedData, envelopedData types included. Scripts to check against + RFC4134 examples draft and interop and consistency checks of many + content types and variants. + [Steve Henson] + + *) Add options to enc utility to support use of zlib compression BIO. + [Steve Henson] + + *) Extend mk1mf to support importing of options and assembly language + files from Configure script, currently only included in VC-WIN32. + The assembly language rules can now optionally generate the source + files from the associated perl scripts. + [Steve Henson] + + *) Implement remaining functionality needed to support GOST ciphersuites. + Interop testing has been performed using CryptoPro implementations. + [Victor B. Wagner <vitus@cryptocom.ru>] + + *) s390x assembler pack. + [Andy Polyakov] + + *) ARMv4 assembler pack. ARMv4 refers to v4 and later ISA, not CPU + "family." + [Andy Polyakov] + + *) Implement Opaque PRF Input TLS extension as specified in + draft-rescorla-tls-opaque-prf-input-00.txt. Since this is not an + official specification yet and no extension type assignment by + IANA exists, this extension (for now) will have to be explicitly + enabled when building OpenSSL by providing the extension number + to use. For example, specify an option + + -DTLSEXT_TYPE_opaque_prf_input=0x9527 + + to the "config" or "Configure" script to enable the extension, + assuming extension number 0x9527 (which is a completely arbitrary + and unofficial assignment based on the MD5 hash of the Internet + Draft). Note that by doing so, you potentially lose + interoperability with other TLS implementations since these might + be using the same extension number for other purposes. + + SSL_set_tlsext_opaque_prf_input(ssl, src, len) is used to set the + opaque PRF input value to use in the handshake. This will create + an interal copy of the length-'len' string at 'src', and will + return non-zero for success. + + To get more control and flexibility, provide a callback function + by using + + SSL_CTX_set_tlsext_opaque_prf_input_callback(ctx, cb) + SSL_CTX_set_tlsext_opaque_prf_input_callback_arg(ctx, arg) + + where + + int (*cb)(SSL *, void *peerinput, size_t len, void *arg); + void *arg; + + Callback function 'cb' will be called in handshakes, and is + expected to use SSL_set_tlsext_opaque_prf_input() as appropriate. + Argument 'arg' is for application purposes (the value as given to + SSL_CTX_set_tlsext_opaque_prf_input_callback_arg() will directly + be provided to the callback function). The callback function + has to return non-zero to report success: usually 1 to use opaque + PRF input just if possible, or 2 to enforce use of the opaque PRF + input. In the latter case, the library will abort the handshake + if opaque PRF input is not successfully negotiated. + + Arguments 'peerinput' and 'len' given to the callback function + will always be NULL and 0 in the case of a client. A server will + see the client's opaque PRF input through these variables if + available (NULL and 0 otherwise). Note that if the server + provides an opaque PRF input, the length must be the same as the + length of the client's opaque PRF input. + + Note that the callback function will only be called when creating + a new session (session resumption can resume whatever was + previously negotiated), and will not be called in SSL 2.0 + handshakes; thus, SSL_CTX_set_options(ctx, SSL_OP_NO_SSLv2) or + SSL_set_options(ssl, SSL_OP_NO_SSLv2) is especially recommended + for applications that need to enforce opaque PRF input. + + [Bodo Moeller] + + *) Update ssl code to support digests other than SHA1+MD5 for handshake + MAC. + + [Victor B. Wagner <vitus@cryptocom.ru>] + + *) Add RFC4507 support to OpenSSL. This includes the corrections in + RFC4507bis. The encrypted ticket format is an encrypted encoded + SSL_SESSION structure, that way new session features are automatically + supported. + + If a client application caches session in an SSL_SESSION structure + support is transparent because tickets are now stored in the encoded + SSL_SESSION. + + The SSL_CTX structure automatically generates keys for ticket + protection in servers so again support should be possible + with no application modification. + + If a client or server wishes to disable RFC4507 support then the option + SSL_OP_NO_TICKET can be set. + + Add a TLS extension debugging callback to allow the contents of any client + or server extensions to be examined. + + This work was sponsored by Google. + [Steve Henson] + + *) Final changes to avoid use of pointer pointer casts in OpenSSL. + OpenSSL should now compile cleanly on gcc 4.2 + [Peter Hartley <pdh@utter.chaos.org.uk>, Steve Henson] + + *) Update SSL library to use new EVP_PKEY MAC API. Include generic MAC + support including streaming MAC support: this is required for GOST + ciphersuite support. + [Victor B. Wagner <vitus@cryptocom.ru>, Steve Henson] + + *) Add option -stream to use PKCS#7 streaming in smime utility. New + function i2d_PKCS7_bio_stream() and PEM_write_PKCS7_bio_stream() + to output in BER and PEM format. + [Steve Henson] + + *) Experimental support for use of HMAC via EVP_PKEY interface. This + allows HMAC to be handled via the EVP_DigestSign*() interface. The + EVP_PKEY "key" in this case is the HMAC key, potentially allowing + ENGINE support for HMAC keys which are unextractable. New -mac and + -macopt options to dgst utility. + [Steve Henson] + + *) New option -sigopt to dgst utility. Update dgst to use + EVP_Digest{Sign,Verify}*. These two changes make it possible to use + alternative signing paramaters such as X9.31 or PSS in the dgst + utility. + [Steve Henson] + + *) Change ssl_cipher_apply_rule(), the internal function that does + the work each time a ciphersuite string requests enabling + ("foo+bar"), moving ("+foo+bar"), disabling ("-foo+bar", or + removing ("!foo+bar") a class of ciphersuites: Now it maintains + the order of disabled ciphersuites such that those ciphersuites + that most recently went from enabled to disabled not only stay + in order with respect to each other, but also have higher priority + than other disabled ciphersuites the next time ciphersuites are + enabled again. + + This means that you can now say, e.g., "PSK:-PSK:HIGH" to enable + the same ciphersuites as with "HIGH" alone, but in a specific + order where the PSK ciphersuites come first (since they are the + most recently disabled ciphersuites when "HIGH" is parsed). + + Also, change ssl_create_cipher_list() (using this new + funcionality) such that between otherwise identical + cihpersuites, ephemeral ECDH is preferred over ephemeral DH in + the default order. + [Bodo Moeller] + + *) Change ssl_create_cipher_list() so that it automatically + arranges the ciphersuites in reasonable order before starting + to process the rule string. Thus, the definition for "DEFAULT" + (SSL_DEFAULT_CIPHER_LIST) now is just "ALL:!aNULL:!eNULL", but + remains equivalent to "AES:ALL:!aNULL:!eNULL:+aECDH:+kRSA:+RC4:@STRENGTH". + This makes it much easier to arrive at a reasonable default order + in applications for which anonymous ciphers are OK (meaning + that you can't actually use DEFAULT). + [Bodo Moeller; suggested by Victor Duchovni] + + *) Split the SSL/TLS algorithm mask (as used for ciphersuite string + processing) into multiple integers instead of setting + "SSL_MKEY_MASK" bits, "SSL_AUTH_MASK" bits, "SSL_ENC_MASK", + "SSL_MAC_MASK", and "SSL_SSL_MASK" bits all in a single integer. + (These masks as well as the individual bit definitions are hidden + away into the non-exported interface ssl/ssl_locl.h, so this + change to the definition of the SSL_CIPHER structure shouldn't + affect applications.) This give us more bits for each of these + categories, so there is no longer a need to coagulate AES128 and + AES256 into a single algorithm bit, and to coagulate Camellia128 + and Camellia256 into a single algorithm bit, which has led to all + kinds of kludges. + + Thus, among other things, the kludge introduced in 0.9.7m and + 0.9.8e for masking out AES256 independently of AES128 or masking + out Camellia256 independently of AES256 is not needed here in 0.9.9. + + With the change, we also introduce new ciphersuite aliases that + so far were missing: "AES128", "AES256", "CAMELLIA128", and + "CAMELLIA256". + [Bodo Moeller] + + *) Add support for dsa-with-SHA224 and dsa-with-SHA256. + Use the leftmost N bytes of the signature input if the input is + larger than the prime q (with N being the size in bytes of q). + [Nils Larsch] + + *) Very *very* experimental PKCS#7 streaming encoder support. Nothing uses + it yet and it is largely untested. + [Steve Henson] + + *) Add support for the ecdsa-with-SHA224/256/384/512 signature types. + [Nils Larsch] + + *) Initial incomplete changes to avoid need for function casts in OpenSSL + some compilers (gcc 4.2 and later) reject their use. Safestack is + reimplemented. Update ASN1 to avoid use of legacy functions. + [Steve Henson] + + *) Win32/64 targets are linked with Winsock2. + [Andy Polyakov] + + *) Add an X509_CRL_METHOD structure to allow CRL processing to be redirected + to external functions. This can be used to increase CRL handling + efficiency especially when CRLs are very large by (for example) storing + the CRL revoked certificates in a database. + [Steve Henson] + + *) Overhaul of by_dir code. Add support for dynamic loading of CRLs so + new CRLs added to a directory can be used. New command line option + -verify_return_error to s_client and s_server. This causes real errors + to be returned by the verify callback instead of carrying on no matter + what. This reflects the way a "real world" verify callback would behave. + [Steve Henson] + + *) GOST engine, supporting several GOST algorithms and public key formats. + Kindly donated by Cryptocom. + [Cryptocom] + + *) Partial support for Issuing Distribution Point CRL extension. CRLs + partitioned by DP are handled but no indirect CRL or reason partitioning + (yet). Complete overhaul of CRL handling: now the most suitable CRL is + selected via a scoring technique which handles IDP and AKID in CRLs. + [Steve Henson] + + *) New X509_STORE_CTX callbacks lookup_crls() and lookup_certs() which + will ultimately be used for all verify operations: this will remove the + X509_STORE dependency on certificate verification and allow alternative + lookup methods. X509_STORE based implementations of these two callbacks. + [Steve Henson] + + *) Allow multiple CRLs to exist in an X509_STORE with matching issuer names. + Modify get_crl() to find a valid (unexpired) CRL if possible. + [Steve Henson] + + *) New function X509_CRL_match() to check if two CRLs are identical. Normally + this would be called X509_CRL_cmp() but that name is already used by + a function that just compares CRL issuer names. Cache several CRL + extensions in X509_CRL structure and cache CRLDP in X509. + [Steve Henson] + + *) Store a "canonical" representation of X509_NAME structure (ASN1 Name) + this maps equivalent X509_NAME structures into a consistent structure. + Name comparison can then be performed rapidly using memcmp(). + [Steve Henson] + + *) Non-blocking OCSP request processing. Add -timeout option to ocsp + utility. + [Steve Henson] + + *) Allow digests to supply their own micalg string for S/MIME type using + the ctrl EVP_MD_CTRL_MICALG. + [Steve Henson] + + *) During PKCS7 signing pass the PKCS7 SignerInfo structure to the + EVP_PKEY_METHOD before and after signing via the EVP_PKEY_CTRL_PKCS7_SIGN + ctrl. It can then customise the structure before and/or after signing + if necessary. + [Steve Henson] + + *) New function OBJ_add_sigid() to allow application defined signature OIDs + to be added to OpenSSLs internal tables. New function OBJ_sigid_free() + to free up any added signature OIDs. + [Steve Henson] + + *) New functions EVP_CIPHER_do_all(), EVP_CIPHER_do_all_sorted(), + EVP_MD_do_all() and EVP_MD_do_all_sorted() to enumerate internal + digest and cipher tables. New options added to openssl utility: + list-message-digest-algorithms and list-cipher-algorithms. + [Steve Henson] + + *) Change the array representation of binary polynomials: the list + of degrees of non-zero coefficients is now terminated with -1. + Previously it was terminated with 0, which was also part of the + value; thus, the array representation was not applicable to + polynomials where t^0 has coefficient zero. This change makes + the array representation useful in a more general context. + [Douglas Stebila] + + *) Various modifications and fixes to SSL/TLS cipher string + handling. For ECC, the code now distinguishes between fixed ECDH + with RSA certificates on the one hand and with ECDSA certificates + on the other hand, since these are separate ciphersuites. The + unused code for Fortezza ciphersuites has been removed. + + For consistency with EDH, ephemeral ECDH is now called "EECDH" + (not "ECDHE"). For consistency with the code for DH + certificates, use of ECDH certificates is now considered ECDH + authentication, not RSA or ECDSA authentication (the latter is + merely the CA's signing algorithm and not actively used in the + protocol). + + The temporary ciphersuite alias "ECCdraft" is no longer + available, and ECC ciphersuites are no longer excluded from "ALL" + and "DEFAULT". The following aliases now exist for RFC 4492 + ciphersuites, most of these by analogy with the DH case: + + kECDHr - ECDH cert, signed with RSA + kECDHe - ECDH cert, signed with ECDSA + kECDH - ECDH cert (signed with either RSA or ECDSA) + kEECDH - ephemeral ECDH + ECDH - ECDH cert or ephemeral ECDH + + aECDH - ECDH cert + aECDSA - ECDSA cert + ECDSA - ECDSA cert + + AECDH - anonymous ECDH + EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") + + [Bodo Moeller] + + *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. + Use correct micalg parameters depending on digest(s) in signed message. + [Steve Henson] + + *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process + an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. + [Steve Henson] + + *) Initial engine support for EVP_PKEY_METHOD. New functions to permit + an engine to register a method. Add ENGINE lookups for methods and + functional reference processing. + [Steve Henson] + + *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of + EVP_{Sign,Verify}* which allow an application to customise the signature + process. + [Steve Henson] + + *) New -resign option to smime utility. This adds one or more signers + to an existing PKCS#7 signedData structure. Also -md option to use an + alternative message digest algorithm for signing. + [Steve Henson] + + *) Tidy up PKCS#7 routines and add new functions to make it easier to + create PKCS7 structures containing multiple signers. Update smime + application to support multiple signers. + [Steve Henson] + + *) New -macalg option to pkcs12 utility to allow setting of an alternative + digest MAC. + [Steve Henson] + + *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. + Reorganize PBE internals to lookup from a static table using NIDs, + add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: + EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative + PRF which will be automatically used with PBES2. + [Steve Henson] + + *) Replace the algorithm specific calls to generate keys in "req" with the + new API. + [Steve Henson] + + *) Update PKCS#7 enveloped data routines to use new API. This is now + supported by any public key method supporting the encrypt operation. A + ctrl is added to allow the public key algorithm to examine or modify + the PKCS#7 RecipientInfo structure if it needs to: for RSA this is + a no op. + [Steve Henson] + + *) Add a ctrl to asn1 method to allow a public key algorithm to express + a default digest type to use. In most cases this will be SHA1 but some + algorithms (such as GOST) need to specify an alternative digest. The + return value indicates how strong the prefernce is 1 means optional and + 2 is mandatory (that is it is the only supported type). Modify + ASN1_item_sign() to accept a NULL digest argument to indicate it should + use the default md. Update openssl utilities to use the default digest + type for signing if it is not explicitly indicated. + [Steve Henson] + + *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New + EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant + signing method from the key type. This effectively removes the link + between digests and public key types. + [Steve Henson] + + *) Add an OID cross reference table and utility functions. Its purpose is to + translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, + rsaEncryption. This will allow some of the algorithm specific hackery + needed to use the correct OID to be removed. + [Steve Henson] + + *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO + structures for PKCS7_sign(). They are now set up by the relevant public + key ASN1 method. + [Steve Henson] + + *) Add provisional EC pkey method with support for ECDSA and ECDH. + [Steve Henson] + + *) Add support for key derivation (agreement) in the API, DH method and + pkeyutl. + [Steve Henson] + + *) Add DSA pkey method and DH pkey methods, extend DH ASN1 method to support + public and private key formats. As a side effect these add additional + command line functionality not previously available: DSA signatures can be + generated and verified using pkeyutl and DH key support and generation in + pkey, genpkey. + [Steve Henson] + + *) BeOS support. + [Oliver Tappe <zooey@hirschkaefer.de>] + + *) New make target "install_html_docs" installs HTML renditions of the + manual pages. + [Oliver Tappe <zooey@hirschkaefer.de>] + + *) New utility "genpkey" this is analagous to "genrsa" etc except it can + generate keys for any algorithm. Extend and update EVP_PKEY_METHOD to + support key and parameter generation and add initial key generation + functionality for RSA. + [Steve Henson] + + *) Add functions for main EVP_PKEY_method operations. The undocumented + functions EVP_PKEY_{encrypt,decrypt} have been renamed to + EVP_PKEY_{encrypt,decrypt}_old. + [Steve Henson] + + *) Initial definitions for EVP_PKEY_METHOD. This will be a high level public + key API, doesn't do much yet. + [Steve Henson] + + *) New function EVP_PKEY_asn1_get0_info() to retrieve information about + public key algorithms. New option to openssl utility: + "list-public-key-algorithms" to print out info. + [Steve Henson] + + *) Implement the Supported Elliptic Curves Extension for + ECC ciphersuites from draft-ietf-tls-ecc-12.txt. + [Douglas Stebila] + + *) Don't free up OIDs in OBJ_cleanup() if they are in use by EVP_MD or + EVP_CIPHER structures to avoid later problems in EVP_cleanup(). + [Steve Henson] + + *) New utilities pkey and pkeyparam. These are similar to algorithm specific + utilities such as rsa, dsa, dsaparam etc except they process any key + type. + [Steve Henson] + + *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New + functions EVP_PKEY_print_public(), EVP_PKEY_print_private(), + EVP_PKEY_print_param() to print public key data from an EVP_PKEY + structure. + [Steve Henson] + + *) Initial support for pluggable public key ASN1. + De-spaghettify the public key ASN1 handling. Move public and private + key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate + algorithm specific handling to a single module within the relevant + algorithm directory. Add functions to allow (near) opaque processing + of public and private key structures. + [Steve Henson] + + *) Implement the Supported Point Formats Extension for + ECC ciphersuites from draft-ietf-tls-ecc-12.txt. + [Douglas Stebila] + + *) Add initial support for RFC 4279 PSK TLS ciphersuites. Add members + for the psk identity [hint] and the psk callback functions to the + SSL_SESSION, SSL and SSL_CTX structure. + + New ciphersuites: + PSK-RC4-SHA, PSK-3DES-EDE-CBC-SHA, PSK-AES128-CBC-SHA, + PSK-AES256-CBC-SHA + + New functions: + SSL_CTX_use_psk_identity_hint + SSL_get_psk_identity_hint + SSL_get_psk_identity + SSL_use_psk_identity_hint + + [Mika Kousa and Pasi Eronen of Nokia Corporation] + + *) Add RFC 3161 compliant time stamp request creation, response generation + and response verification functionality. + [Zoltán Glózik <zglozik@opentsa.org>, The OpenTSA Project] + + *) Add initial support for TLS extensions, specifically for the server_name + extension so far. The SSL_SESSION, SSL_CTX, and SSL data structures now + have new members for a host name. The SSL data structure has an + additional member SSL_CTX *initial_ctx so that new sessions can be + stored in that context to allow for session resumption, even after the + SSL has been switched to a new SSL_CTX in reaction to a client's + server_name extension. + + New functions (subject to change): + + SSL_get_servername() + SSL_get_servername_type() + SSL_set_SSL_CTX() + + New CTRL codes and macros (subject to change): + + SSL_CTRL_SET_TLSEXT_SERVERNAME_CB + - SSL_CTX_set_tlsext_servername_callback() + SSL_CTRL_SET_TLSEXT_SERVERNAME_ARG + - SSL_CTX_set_tlsext_servername_arg() + SSL_CTRL_SET_TLSEXT_HOSTNAME - SSL_set_tlsext_host_name() + + openssl s_client has a new '-servername ...' option. + + openssl s_server has new options '-servername_host ...', '-cert2 ...', + '-key2 ...', '-servername_fatal' (subject to change). This allows + testing the HostName extension for a specific single host name ('-cert' + and '-key' remain fallbacks for handshakes without HostName + negotiation). If the unrecogninzed_name alert has to be sent, this by + default is a warning; it becomes fatal with the '-servername_fatal' + option. + + [Peter Sylvester, Remy Allais, Christophe Renou] + + *) Whirlpool hash implementation is added. + [Andy Polyakov] + + *) BIGNUM code on 64-bit SPARCv9 targets is switched from bn(64,64) to + bn(64,32). Because of instruction set limitations it doesn't have + any negative impact on performance. This was done mostly in order + to make it possible to share assembler modules, such as bn_mul_mont + implementations, between 32- and 64-bit builds without hassle. + [Andy Polyakov] + + *) Move code previously exiled into file crypto/ec/ec2_smpt.c + to ec2_smpl.c, and no longer require the OPENSSL_EC_BIN_PT_COMP + macro. + [Bodo Moeller] + + *) New candidate for BIGNUM assembler implementation, bn_mul_mont, + dedicated Montgomery multiplication procedure, is introduced. + BN_MONT_CTX is modified to allow bn_mul_mont to reach for higher + "64-bit" performance on certain 32-bit targets. + [Andy Polyakov] + + *) New option SSL_OP_NO_COMP to disable use of compression selectively + in SSL structures. New SSL ctrl to set maximum send fragment size. + Save memory by seeting the I/O buffer sizes dynamically instead of + using the maximum available value. + [Steve Henson] + + *) New option -V for 'openssl ciphers'. This prints the ciphersuite code + in addition to the text details. + [Bodo Moeller] + + *) Very, very preliminary EXPERIMENTAL support for printing of general + ASN1 structures.

Command line switches to support + these in the 'rsa' and 'dsa' utilities. + [Steve Henson] + + *) Support for PKCS#1 RSAPublicKey format on rsa utility command line. + [Steve Henson] + + *) Remove the ancient ASN1_METHOD code. This was only ever used in one + place for the (very old) "NETSCAPE" format certificates which are now + handled using new ASN1 code equivalents. + [Steve Henson] + + *) Let the TLSv1_method() etc. functions return a 'const' SSL_METHOD + pointer and make the SSL_METHOD parameter in SSL_CTX_new, + SSL_CTX_set_ssl_version and SSL_set_ssl_method 'const'. + [Nils Larsch] + + *) Modify CRL distribution points extension code to print out previously + unsupported fields.
