* tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't workDenys Vlasenko2017-01-241-5/+10
| | | | | | | | | | Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes. In libbb, md5_end() and shaX_end() are extended to return result size instead of void - this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

| | | | | | | | | | | | | | | | | | | | If the target can tolerate these issues, then gcc is smart enough to generate the same code (x86_64 produces the same code). If the target can't, then it needs the memcpy anyways. libbb/hash_md5_sha.c: In function 'common64_end': libbb/hash_md5_sha.c:87:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[64 - 8]) = t; libbb/hash_md5_sha.c: In function 'sha512_end': libbb/hash_md5_sha.c:886:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[128 - 8]) = t; libbb/hash_md5_sha.c:889:4: warning: dereferencing type-punned pointer will break strict-aliasing rules *(uint64_t *) (&ctx->wbuffer[128 - 16]) = t; Signed-off-by: Mike Frysinger <vapier@gentoo.org>
