Keccak256 is optimized for cases that call Sum() just once.

Keccack512 is an optimized alternative to NewKeccak512/Write/Sum, like Keccack256.

New224 creates a new SHA3-224 hash.

New256 creates a new SHA3-256 hash.

New384 creates a new SHA3-384 hash.

New512 creates a new SHA3-512 hash.

NewKeccak256 creates a new Keccak-256 hash.

NewKeccak256SingleSum is like NewKeccak256, but the returned hash must be Reset() after calling Sum().

NewKeccak512 creates a new Keccak-512 hash.

NewKeccak512SingleSum returns an optimized instance, like NewKeccak256SingleSum().

NewShake128 creates a new SHAKE128 variable-output-length ShakeHash.

NewShake256 creates a new SHAKE128 variable-output-length ShakeHash.

ShakeSum128 writes an arbitrary-length digest of data into hash.

ShakeSum256 writes an arbitrary-length digest of data into hash.

Sum224 returns the SHA3-224 digest of the data.

Sum256 returns the SHA3-256 digest of the data.

Sum384 returns the SHA3-384 digest of the data.

Sum512 returns the SHA3-512 digest of the data.

ShakeHash defines the interface to hash functions that support arbitrary-length output.
