Consider supporting NIST SP 800-185 (Approved SHA-3 variants)

[dd86k]

Priority: Low

In 2016, NIST published SP.800-185 describing additional SHA-3 derived functions:

• cSHAKExxx(X,L,N,S): "A version of SHAKE supporting explicit domain separation via customization parameters."
• KMACxxx/KMACXOFxxx(K,X,L,S): "A keyed hash function based on Keccak. Can also be used without a key as a regular hash function."
• TupleHashxxx/TupleHashXOFxxx(X,L,S): "A function for hashing tuples of strings. The output of this function depends on both the contents and the sequence of input strings."
• ParallelHashxxx/ParallelHashXOFxxx(X,B,L,S): "A function designed to exploit parallelism in modern processors for faster hashing. Unlike KangarooTwelve, does not use reduced-round Keccak."

The regular functions are fine anyway.

Honestly, the only ones interesting are KangarooTwelve and MarsupilamiFourteen.

Maybe has a separate package.
