 OpenSSL CHANGES
 _______________

 Changes between 1.0.0e and 1.0.1  [xx XXX xxxx]

  *) 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 verify.
     [Peter Eckersley <pde@eff.org> and Ben Laurie]

  *) 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]

  *) 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").
