This Recommendation specifies four SHA-3-derived functions: cSHAKE, KMAC, TupleHash, and ParallelHash. cSHAKE is a customizable variant of the SHAKE functions defined in FIPS 202. KMAC (for KECCAK Message Authentication Code) is a variable-length message authentication code algorithm based on KECCAK; it can also be used as a pseudorandom function. TupleHash is a variable-length hash function designed to hash tuples of input strings unambiguously. ParallelHash is a variable-length hash function that can hash very long messages in parallel.
