Major cleanup of the MD and SHA digests. - Use the new vector byte-order conversion functions where appropriate. - Use memset_s() instead of memset() where appropriate. - Use consistent names and types for function arguments. - Reindent, rename and reorganize to conform to Cryb style and idiom. SHA224 and SHA256 were left mostly unchanged. MD2 and MD4 were completely rewritten as the previous versions (taken from XySSL) seem to have been copied from RSAREF. This breaks the ABI as some context structures have grown or shrunk and some function arguments have been changed from int to size_t. 2017-03-19 23:13:47 +00:00			`uint32_t state[4];`

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. 2014-07-12 21:57:31 +00:00			`void md5_final(md5_ctx , uint8_t );`
