Detailed Description

internal dcp_hash context structure

Field Documentation

algo

dcp_hash_algo_t _dcp_hash_ctx_internal::algo

selected algorithm from the set of supported algorithms

blk

dcp_hash_block_t _dcp_hash_ctx_internal::blk

memory buffer. only full blocks are written to DCP during hash updates

blksz

size_t _dcp_hash_ctx_internal::blksz

number of valid bytes in memory buffer

ctrl0

uint32_t _dcp_hash_ctx_internal::ctrl0

HASH_INIT and HASH_TERM flags

fullMessageSize

uint32_t _dcp_hash_ctx_internal::fullMessageSize

track message size

runningHash

uint32_t _dcp_hash_ctx_internal::runningHash[9]

running hash. up to SHA-256 plus size, that is 36 bytes.

state

dcp_hash_algo_state_t _dcp_hash_ctx_internal::state

finite machine state of the hash software process
