Changes between 0.9.8a and 0.9.9 [xx XXX xxxx]
+ *) 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_hostname()
+
+ 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]
+
+ *) Disable rogue ciphersuites:
+
+ - SSLv2 0x08 0x00 0x80 ("RC4-64-MD5")
+ - SSLv3/TLSv1 0x00 0x61 ("EXP1024-RC2-CBC-MD5")
+ - SSLv3/TLSv1 0x00 0x60 ("EXP1024-RC4-MD5")
+
+ The latter two were purportedly from
+ draft-ietf-tls-56-bit-ciphersuites-0[01].txt, but do not really
+ appear there.
+
+ Other ciphersuites from draft-ietf-tls-56-bit-ciphersuites-01.txt
+ remain enabled for now, but are just as unofficial, and the ID
+ has long expired; these will probably disappear soon.
+ [Bodo Moeller]
+
+ *) 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. This currently produces rather ugly output and doesn't
+ handle several customised structures at all.
+ [Steve Henson]
+
*) Integrated support for PVK file format and some related formats such
as MS PUBLICKEYBLOB and PRIVATEKEYBLOB. Command line switches to support
these in the 'rsa' and 'dsa' utilities.
*) Add print and set support for Issuing Distribution Point CRL extension.

+ Changes between 0.9.8a and 0.9.8b [XX xxx XXXX]
+
+ *) When applying a cipher rule check to see if string match is an explicit
+ cipher suite and only match that one cipher suite if it is.
+ [Steve Henson]
+
+ *) Link in manifests for VC++ if needed.
+ [Austin Ziegler <halostatue@gmail.com>]
+
+ *) Update support for ECC-based TLS ciphersuites according to
+ draft-ietf-tls-ecc-12.txt with proposed changes (but without
+ TLS extensions, which are supported starting with the 0.9.9
+ branch, not in the OpenSSL 0.9.8 branch).
+ [Douglas Stebila]
+
+ *) New functions EVP_CIPHER_CTX_new() and EVP_CIPHER_CTX_free() to support
+ opaque EVP_CIPHER_CTX handling.
+ [Steve Henson]
+
+ *) Fixes and enhancements to zlib compression code. We now only use
+ "zlib1.dll" and use the default __cdecl calling convention on Win32
+ to conform with the standards mentioned here:
+ http://www.zlib.net/DLL_FAQ.txt
+ Static zlib linking now works on Windows and the new --with-zlib-include
+ --with-zlib-lib options to Configure can be used to supply the location
+ of the headers and library. Gracefully handle case where zlib library
+ can't be loaded.
+ [Steve Henson]
+
+ *) Several fixes and enhancements to the OID generation code. The old code
+ sometimes allowed invalid OIDs (1.X for X >= 40 for example), couldn't
+ handle numbers larger than ULONG_MAX, truncated printing and had a
+ non standard OBJ_obj2txt() behaviour.
+ [Steve Henson]
+
+ *) Add support for building of engines under engine/ as shared libraries
+ under VC++ build system.
+ [Steve Henson]
+
+ *) Corrected the numerous bugs in the Win32 path splitter in DSO.
+ Hopefully, we will not see any false combination of paths any more.
+ [Richard Levitte]
+
+ Changes between 0.9.8 and 0.9.8a [11 Oct 2005]
+
+ *) Remove the functionality of SSL_OP_MSIE_SSLV2_RSA_PADDING
+ (part of SSL_OP_ALL). This option used to disable the
+ countermeasure against man-in-the-middle protocol-version
+ rollback in the SSL 2.0 server implementation, which is a bad
+ idea. (CVE-2005-2969)
+
+ [Bodo Moeller; problem pointed out by Yutaka Oiwa (Research Center
+ for Information Security, National Institute of Advanced Industrial
+ Science and Technology [AIST], Japan)]
+
+ *) Add two function to clear and return the verify parameter flags.
+ [Steve Henson]
*) Keep cipherlists sorted in the source instead of sorting them at
runtime, thus removing the need for a lock.
*) Extended Windows CE support.

*) Initialize SSL_METHOD structures at compile time instead of during
runtime, thus removing the need for a lock.

- Changes between 0.9.7g and 0.9.7h [XX xxx XXXX]
+ Changes between 0.9.7h and 0.9.7i [14 Oct 2005]
+
+ *) Wrapped the definition of EVP_MAX_MD_SIZE in a #ifdef OPENSSL_FIPS.
+ The value now differs depending on if you build for FIPS or not.
+ BEWARE! A program linked with a shared FIPSed libcrypto can't be
+ safely run with a non-FIPSed libcrypto, as it may crash because of
+ the difference induced by this change.

*) Minimal support for X9.31 signatures and PSS padding modes. This is
mainly for FIPS compliance and not fully integrated at this stage.
Changes between 0.9.7f and 0.9.7g [11 Apr 2005]
+ [NB: OpenSSL 0.9.7h and later 0.9.7 patch levels were released after
