+ Changes between 1.0.1 and 1.0.2 [xx XXX xxxx]
+
+ *) Transparently support X9.42 DH parameters when calling
+ PEM_read_bio_DHparameters. This means existing applications can handle
+ the new parameter format automatically.
+ [Steve Henson]
+
+ *) Initial experimental support for X9.42 DH parameter format: mainly
+ to support use of 'q' parameter for RFC5114 parameters.
+ [Steve Henson]
+
+ *) Add DH parameters from RFC5114 including test data to dhtest.
+ [Steve Henson]
+
+ *) Support for automatic EC temporary key parameter selection. If enabled
+ the most preferred EC parameters are automatically used instead of
+ hardcoded fixed parameters. Now a server just has to call:
+ SSL_CTX_set_ecdh_auto(ctx, 1) and the server will automatically
+ support ECDH and use the most appropriate parameters.
+ [Steve Henson]
+
+ *) Enhance and tidy EC curve and point format TLS extension code. Use
+ static structures instead of allocation if default values are used.
+ New ctrls to set curves we wish to support and to retrieve shared curves.
+ Print out shared curves in s_server. New options to s_server and s_client
+ to set list of supported curves.
+ [Steve Henson]
+
+ *) New ctrls to retrieve supported signature algorithms and
+ supported curve values as an array of NIDs. Extend openssl utility
+ to print out received values.
+ [Steve Henson]
+
+ *) Add new APIs EC_curve_nist2nid and EC_curve_nid2nist which convert
+ between NIDs and the more common NIST names such as "P-256". Enhance
+ ecparam utility and ECC method to recognise the NIST names for curves.
+ [Steve Henson]
+
+ *) Enhance SSL/TLS certificate chain handling to support different
+ chains for each certificate instead of one chain in the parent SSL_CTX.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuite client authentication: where both
+ server and client use DH certificates with common parameters.
+ [Steve Henson]
+
+ *) Support for fixed DH ciphersuites: those requiring DH server
+ certificates.
+ [Steve Henson]
+
+ Changes between 1.0.1 and 1.0.1a [19 Apr 2012]
+
+ *) Check for potentially exploitable overflows in asn1_d2i_read_bio
+ BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
+ in CRYPTO_realloc_clean.
+
+ Thanks to Tavis Ormandy, Google Security Team, for discovering this
+ issue and to Adam Langley <agl@chromium.org> for fixing it.
+ (CVE-2012-2110)
+ [Adam Langley (Google), Tavis Ormandy, Google Security Team]
+
+ *) Don't allow TLS 1.2 SHA-256 ciphersuites in TLS 1.0, 1.1 connections.
+ [Adam Langley]
+
+ *) Workarounds for some broken servers that "hang" if a client hello
+ record length exceeds 255 bytes:
+
+ 1. 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.
+
+ *) 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. 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
