Field Documentation

pKey

uint8_t* CryptoCC32XX_HmacParams::pKey

pointer to hash key

moreData

uint8_t CryptoCC32XX_HmacParams::moreData

True value will NOT close the HMAC HW machine

pContext

void* CryptoCC32XX_HmacParams::pContext

Reserved for future use

first

uint8_t CryptoCC32XX_HmacParams::first

True if no data was written to the HMAC HW machine

digestCount

uint32_t CryptoCC32XX_HmacParams::digestCount

Number of bytes that was written to the HMAC HW machine

innerDigest

uint8_t CryptoCC32XX_HmacParams::innerDigest[ 32]

Intermediate digest

buff

uint8_t CryptoCC32XX_HmacParams::buff[ 64]

Internal buffer - used when moreData sets to true and the data length is not an integer multiple of blockSize

buffLen

uint32_t CryptoCC32XX_HmacParams::buffLen

Number of bytes in buff

blockSize

uint32_t CryptoCC32XX_HmacParams::blockSize

Block size of the hashing algorithm in use
