sha3_224 top-level constant
SHA3-224 is a member of SHA-3 family which uses 224-bit blocks to generate a message digest of 224-bit long.
SHA-3 is a subset of Keccak cryptographic family, standardized by NIST on 2015 to substitute SHA-2 if necessary. Since the algorithm uses the sponge construction, it can generate any arbitrary length of message digest. This implementation generates a 224-bit output using the standard SHA-3 algorithm.
Implementation
const BlockHashBase sha3_224 = _SHA3d224();
