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.
