Member Function Documentation

xor_state()

template<size_t HASHBITS, uint8_t DOMAINBITS>

size_t xor_state ( size_t offset, const uint8_t * input, size_t n_in )

protected

Add stream data up to block size into Keccak state via XOR.

absorb_padding()

template<size_t HASHBITS, uint8_t DOMAINBITS>

void absorb_padding ( size_t offset, uint8_t trail = 0x01 )

protected

Pad stream from offset to block boundary into Keccak state via XOR. The trail argument must contain the termination bit, optionally preceeded by additional (LSB) bits for domain separation. A permutation is carried out if the trailing padding bits do not fit into the remaining block length.

byte_rate()

template<size_t HASHBITS, uint8_t DOMAINBITS>

reset()

update()

template<size_t HASHBITS, uint8_t DOMAINBITS>

get_hash()

size_t get_hash

(

uint8_t

hashvalue[HASHBITS/8]

Switch from absorbing into squeezing mode and return digest.

squeeze_digest()

template<size_t HASHBITS, uint8_t DOMAINBITS>

void squeeze_digest	(	uint8_t *	output,
		size_t	n_out
	)

Read out the current Keccak state and permute as needed.
