Changes between 1.0.1 and 1.1.0 [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]
+
+ *) Update fips_test_suite to support multiple command line options. New
+ test to induce all self test errors in sequence and check expected
+ failures.
+ [Steve Henson]
+
+ *) Add FIPS_{rsa,dsa,ecdsa}_{sign,verify} functions which digest and
+ sign or verify all in one operation.
+ [Steve Henson]
+
+ *) Add fips_algvs: a multicall fips utility incorporaing all the algorithm
+ test programs and fips_test_suite. Includes functionality to parse
+ the minimal script output of fipsalgest.pl directly.
+ [Steve Henson]
+
+ *) Add authorisation parameter to FIPS_module_mode_set().
+ [Steve Henson]
+
*) Add FIPS selftest for ECDH algorithm using P-224 and B-233 curves.

security.
[Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
- *) 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]
-
*) New function OPENSSL_gmtime_diff to find the difference in days
and seconds between two tm structures. This will be used to provide
additional functionality for ASN1_TIME.
Changes between 1.0.0f and 1.0.1 [xx XXX xxxx]
+ *) 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
keep original code iff non-FIPS operations are allowed.
[Steve Henson]
- *) Add -attime option to openssl verify.
- [Peter Eckersley <pde@eff.org> and Ben Laurie]
+ *) 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]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
- *) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
- elliptic curve NIST-P224 with constant-time single point multiplication on
- typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
- (while EC_GROUP_new_curve_GFp() currently won't and prefers the more
- flexible implementations).
-
- The implementation requires support for the nonstandard type __uint128_t,
- and so is disabled by default. To include this in your build of OpenSSL,
- use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
- and run "make depend" (or "make update").
- [Emilia Käsper <emilia.kasper@esat.kuleuven.be> (Google)]
-
*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
[Robin Seggelmann <seggelmann@fh-muenster.de>]
Add command line options to s_client/s_server.

+ Changes between 1.0.0e and 1.0.0f [4 Jan 2012]
+
+ *) Nadhem Alfardan and Kenny Paterson have discovered an extension
+ of the Vaudenay padding oracle attack on CBC mode encryption
+ which enables an efficient plaintext recovery attack against
+ the OpenSSL implementation of DTLS. Their attack exploits timing
+ differences arising during decryption processing. A research
+ paper describing this attack can be found at:
+ http://www.isg.rhul.ac.uk/~kp/dtls.pdf
+ Thanks go to Nadhem Alfardan and Kenny Paterson of the Information
+ Security Group at Royal Holloway, University of London
+ (www.isg.rhul.ac.uk) for discovering this flaw and to Robin Seggelmann
+ <seggelmann@fh-muenster.de> and Michael Tuexen <tuexen@fh-muenster.de>
+ for preparing the fix. (CVE-2011-4108)
+ [Robin Seggelmann, Michael Tuexen]
+
+ *) Clear bytes used for block padding of SSL 3.0 records.

+ *) Check parameters are not NULL in GOST ENGINE. (CVE-2012-0027)
+ [Andrey Kulikov <amdeich@gmail.com>]

+ [Adam Langley (Google)]
+
+ *) Fix spurious failures in ecdsatest.c.
+ [Emilia Käsper (Google)]
+
+ *) Fix the BIO_f_buffer() implementation (which was mixing different
+ interpretations of the '..._len' fields).
+ [Adam Langley (Google)]
+
+ *) Fix handling of BN_BLINDING: now BN_BLINDING_invert_ex (rather than
+ BN_BLINDING_invert_ex) calls BN_BLINDING_update, ensuring that concurrent
+ threads won't reuse the same blinding coefficients.
+
+ This also avoids the need to obtain the CRYPTO_LOCK_RSA_BLINDING
+ lock to call BN_BLINDING_invert_ex, and avoids one use of
+ BN_BLINDING_update for each BN_BLINDING structure (previously,
+ the last update always remained unused).
+ [Emilia Käsper (Google)]
*) In ssl3_clear, preserve s3->init_extra along with s3->rbuf.
[Bob Buckholz (Google)]
*) Change 'Configure' script to enable Camellia by default.
