Jussi Kivilinna
jussi.kivilinna at iki.fi
Tue Jun 19 17:51:21 CEST 2018
* src/cipher-proto.h (gcry_md_hash_buffer_t)
(gcry_md_hash_buffers_t): New.
(gcry_md_spec): Add hash_buffer and hash_buffers.
* cipher/md.c (_gcry_md_hash_buffer, _gcry_md_hash_buffers): Use
hash_buffer/hash_buffers from MD spec instead of hard-coding supported
algorithms.
* cipher/blake2.c: Add NULL to MD spec hash_buffer and hash_buffers
pointers.
* cipher/crc.c: Ditto.
* cipher/gostr3411-94.c: Ditto.
* cipher/keccak.c: Ditto.
* cipher/md2.c: Ditto.
* cipher/md4.c: Ditto.
* cipher/md5.c: Ditto.
* cipher/stribog.c: Ditto.
* cipher/tiger.c: Ditto.
* cipher/whirlpool.c: Ditto.
* cipher/rmd160.c (_gcry_rmd160_hash_buffers): New.
(_gcry_digest_spec_rmd160): Add hash_buffer and hash_buffers functions.
* cipher/sha1.c (_gcry_digest_spec_sha1): Add hash_buffer and
hash_buffers functions.
* cipher/sha256.c (_gcry_digest_spec_sha256): Add hash_buffer and
hash_buffers functions.
(_gcry_digest_spec_sha224): Add NULL pointers for hash_buffer and
hash_buffers.
* cipher/sha512.c (_gcry_digest_spec_sha1): Add hash_buffer and
hash_buffers functions.
(_gcry_digest_spec_sha384): Add NULL pointers for hash_buffer and
hash_buffers.
* cipher/sm3.c (_gcry_digest_spec_sha1): Add hash_buffer and
hash_buffers functions.
