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] + + *) Rename FIPS_mode_set and FIPS_mode to FIPS_module_mode_set and + FIPS_module_mode. FIPS_mode and FIPS_mode_set will be implmeneted + outside the validated module in the FIPS capable OpenSSL. + [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] + + *) 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 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. + [Steve Henson] + + *) Modify fipscanisteronly build option to only build the necessary object + files by filtering FIPS_EX_OBJ through a perl script in crypto/Makefile. + [Steve Henson] + + *) Add experimental option FIPSSYMS to give all symbols in + fipscanister.o and FIPS or fips prefix. This will avoid + conflicts with future versions of OpenSSL. Add perl script + util/fipsas.pl to preprocess assembly language source files + and rename any affected symbols. + [Steve Henson] + + *) Add selftest checks and algorithm block of non-fips algorithms in + FIPS mode. Remove DES2 from selftests. + [Steve Henson] + + *) Add ECDSA code to fips module. Add tiny fips_ecdsa_check to just + return internal method without any ENGINE dependencies. Add new + tiny fips sign and verify functions. + [Steve Henson] + + *) New build option no-ec2m to disable characteristic 2 code. + [Steve Henson] + + *) New build option "fipscanisteronly". This only builds fipscanister.o + and (currently) associated fips utilities. Uses the file Makefile.fips + instead of Makefile.org as the prototype. + [Steve Henson] + + *) Add some FIPS mode restrictions to GCM. Add internal IV generator. + Update fips_gcmtest to use IV generator. + [Steve Henson] + + *) Initial, experimental EVP support for AES-GCM. AAD can be input by + setting output buffer to NULL. The *Final function must be + called although it will not retrieve any additional data. The tag + can be set or retrieved with a ctrl. The IV length is by default 12 + bytes (96 bits) but can be set to an alternative value. If the IV + length exceeds the maximum IV length (currently 16 bytes) it cannot be + set before the key. + [Steve Henson] + + *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the + underlying do_cipher function handles all cipher semantics itself + including padding and finalisation. This is useful if (for example) + an ENGINE cipher handles block padding itself. The behaviour of + do_cipher is subtly changed if this flag is set: the return value + is the number of characters written to the output buffer (zero is + no longer an error code) or a negative error code. Also if the + input buffer is NULL and length 0 finalisation should be performed. + [Steve Henson] + + *) If a candidate issuer certificate is already part of the constructed + path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case. + [Steve Henson] + + *) Improve forward-security support: add functions + + void SSL_CTX_set_not_resumable_session_callback(SSL_CTX *ctx, int (*cb)(SSL *ssl, int is_forward_secure)) + void SSL_set_not_resumable_session_callback(SSL *ssl, int (*cb)(SSL *ssl, int is_forward_secure)) + + for use by SSL/TLS servers; the callback function will be called whenever a + new session is created, and gets to decide whether the session may be + cached to make it resumable (return 0) or not (return 1). (As by the + SSL/TLS protocol specifications, the session_id sent by the server will be + empty to indicate that the session is not resumable; also, the server will + not generate RFC 4507 (RFC 5077) session tickets.) + + A simple reasonable callback implementation is to return is_forward_secure. + This parameter will be set to 1 or 0 depending on the ciphersuite selected + by the SSL/TLS server library, indicating whether it can provide forward + security. + [Emilia Käsper (Google)] *) Add Next Protocol Negotiation, http://tools.ietf.org/html/draft-agl-tls-nextprotoneg-00.
