35d982ea57 Rename CPEXX_VER to cpeXX_ver and remove CPEXX_NATTR, which is redundant. 2014-08-01 22:38:36 +00:00

479ffbba4a Remove author and sponsor tags; we'll deal with that some other way. 
Remove $Cryb$ tags as it is likely that the code will move to git.

c658232e3e && is subject to shortcut evaluation, so the second test will not run 
if the first failed.  The ultimate outcome is the same, but using &
instead ensures that, when in verbose mode, we also get output from
the second test.

consisting of the Pearson string hash function and the Murmur3-32 hash
function.

3ed82792fc Fix a bug that affected unterminated buffers: strlcat() would write a NUL 
past the end of the buffer and return one less than the correct length.

c9536ec04b Add tests for the carry operation in sha384 and sha512, which support 
message of up to 2^128 bytes and therefore must use a high / low pair.

340b3240cf Consistently use const void * for data and keys, uint8_t * for digests 
and MACs, and uint8_t, uint32_t or uint64_t (as appropriate) for internal
state.  Also remove a few unnecessary casts.

8e786c5a98 Introduce t_zero (a 256-byte array of zeroes) and t_seq8 (a 256-byte array 
counting up from zero).  Use them to simplify the HMAC-SHA1 test vectors.

5bb81214cc Instead of storing the key in the hmac_sha1_ctx so we can compute the 
output pad in hmac_sha1_final(), prepare a sha1 context in advance and
discard the key as early as possible.
Inspired by Colin Percival's HMAC-SHA-256 implementation.

dffacacccf The spec says XOR here, not OR. Interestingly, it doesn't seem to 
make any difference.
