ethash_keccak256()

struct keccak256 ethash_keccak256	(	const uint8_t *	data,
		size_t	size
	)

ethash_keccakf1600()

void ethash_keccakf1600

(

uint64_t

state[25]

)

The Keccak-f[1600] function.

The implementation of the Keccak-f function with 1600-bit width of the permutation (b). The size of the state is also 1600 bit what gives 25 64-bit words.

Parameters

state

The state of 25 64-bit words on which the permutation is to be performed.
