Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
+ *) 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]
+
+ *) Minor change to DRBG entropy callback semantics. In some cases
+ there is no mutiple of the block length between min_len and
+ max_len. Allow the callback to return more than max_len bytes
+ of entropy but discard any extra: it is the callback's responsibility
+ to ensure that the extra data discarded does not impact the
+ requested amount of entropy.
+ [Steve Henson]
+
+ *) Add PRNG security strength checks to RSA, DSA and ECDSA using
+ information in FIPS186-3, SP800-57 and SP800-131A.
+ [Steve Henson]
+
+ *) CCM support via EVP. Interface is very similar to GCM case except we
+ must supply all data in one chunk (i.e. no update, final) and the
+ message length must be supplied if AAD is used. Add algorithm test
+ support.
+ [Steve Henson]
+
+ *) Initial version of POST overhaul. Add POST callback to allow the status
+ of POST to be monitored and/or failures induced. Modify fips_test_suite
+ to use callback. Always run all selftests even if one fails.
+ [Steve Henson]
+
+ *) XTS support including algorithm test driver in the fips_gcmtest program.
+ Note: this does increase the maximum key length from 32 to 64 bytes but
+ there should be no binary compatibility issues as existing applications
+ will never use XTS mode.
+ [Steve Henson]
+
+ *) Extensive reorganisation of FIPS PRNG behaviour. Remove all dependencies
+ to OpenSSL RAND code and replace with a tiny FIPS RAND API which also
+ performs algorithm blocking for unapproved PRNG types. Also do not
+ set PRNG type in FIPS_mode_set(): leave this to the application.
+ Add default OpenSSL DRBG handling: sets up FIPS PRNG and seeds with
+ the standard OpenSSL PRNG: set additional data to a date time vector.
+ [Steve Henson]
+
+ *) Rename old X9.31 PRNG functions of the form FIPS_rand* to FIPS_x931*.
+ This shouldn't present any incompatibility problems because applications
+ shouldn't be using these directly and any that are will need to rethink
+ anyway as the X9.31 PRNG is now deprecated by FIPS 140-2
+ [Steve Henson]
+
+ *) Extensive self tests and health checking required by SP800-90 DRBG.
+ Remove strength parameter from FIPS_drbg_instantiate and always
+ instantiate at maximum supported strength.
+ [Steve Henson]
+
+ *) Add SRP support.
+ [Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]
+
+ *) Add ECDH code to fips module and fips_ecdhvs for primitives only testing.
+ [Steve Henson]
+
+ *) New algorithm test program fips_dhvs to handle DH primitives only testing.
+ [Steve Henson]
+
+ *) New function DH_compute_key_padded() to compute a DH key and pad with
+ leading zeroes if needed: this complies with SP800-56A et al.
+ [Steve Henson]
+
*) Initial implementation of SP800-90 DRBGs for Hash and CTR. Not used by
anything, incomplete, subject to change and largely untested at present.
