TupleHash

public class TupleHash : IXof, IDigest
TupleHash - a hash designed to simply hash a tuple of input strings, any or all of which may be empty strings, in an unambiguous way with an optional XOF mode.

From NIST Special Publication 800-185 - SHA-3 Derived Functions:cSHAKE, KMAC, TupleHash and ParallelHash
