Keccak
Keccak cryptographic hash function
These tools implement the original Keccak submission – before NIST changed the padding for SHA-3 – in 224, 256, 384 and 512-bit sizes. Keccak-256 is the hash Ethereum uses for addresses, function selectors and event signatures. If you need the standardized function, use the SHA-3 category instead.
