keccak256

keccak256(buffer: ethereum.base_types.Bytes) → Hash32

Computes the keccak256 hash of the input buffer.

Parameters

buffer – Input for the hashing function.

Returns

hash – Output of the hash function.

Return type

ethereum.base_types.Hash32

def keccak256(buffer: Bytes) -> Hash32:
    k = keccak.new(digest_bits=256)
    return Hash32(k.update(buffer).digest())

keccak512

keccak512(buffer: ethereum.base_types.Bytes) → Hash64

Computes the keccak512 hash of the input buffer.

Parameters

buffer – Input for the hashing function.

Returns

hash – Output of the hash function.

Return type

ethereum.base_types.Hash32

def keccak512(buffer: Bytes) -> Hash64:
    k = keccak.new(digest_bits=512)
    return Hash64(k.update(buffer).digest())
