shw_hash_state Struct Reference

Data Fields
unsigned int	partial_count_bytes
uint8_t	partial_block [SHW_HASH_BLOCK_LEN]
uint32_t	state [SHW_HASH_STATE_WORDS]
uint64_t	bit_count

Detailed Description

State for a SHA-1/SHA-2 Hash

(Note to maintainers: state needs to be updated to uint64_t to handle SHA-384/SHA-512)... And bit_count to uint128_t (heh).
