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. Can be + disabled with a no-npn flag to config or Configure. Code donated + by Google. + [Adam Langley <agl@google.com> and Ben Laurie] + + *) Add optional 64-bit optimized implementations of elliptic curves NIST-P224, + NIST-P256, NIST-P521, with constant-time single point multiplication on + typical inputs. Compiler support for the nonstandard type __uint128_t is + required to use this (present in gcc 4.4 and later, for 64-bit builds). + Code made available under Apache License version 2.0. + + Specify "enable-ec_nistp_64_gcc_128" on the Configure (or config) command + line to include this in your build of OpenSSL, and run "make depend" (or + "make update"). This enables the following EC_METHODs: + + EC_GFp_nistp224_method() + EC_GFp_nistp256_method() + EC_GFp_nistp521_method() + + EC_GROUP_new_by_curve_name() will automatically use these (while + EC_GROUP_new_curve_GFp() currently prefers the more flexible + implementations). + [Emilia Käsper, Adam Langley, Bodo Moeller (Google)] + + *) Use type ossl_ssize_t instad of ssize_t which isn't available on + all platforms. Move ssize_t definition from e_os.h to the public + header file e_os2.h as it now appears in public header file cms.h + [Steve Henson] + + *) New -sigopt option to the ca, req and x509 utilities. 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 [xx XXX xxxx] + + *) Fix CVE-2011-4619: make sure we really are receiving a + client hello before rejecting multiple SGC restarts. Thanks to + Ivan Nestlerode <inestlerode@us.ibm.com> for discovering this bug. + [Steve Henson] + Changes between 1.0.0f and 1.0.0g [18 Jan 2012] *) Fix for DTLS DoS issue introduced by fix for CVE-2011-4109. |
