An implementation of the Whirlpool cryptographic hash algorithm.
This is the algorithm recommended by NESSIE (New European Schemes for Signatures, Integrity and Encryption; an European research project).
The constants used by Whirlpool were changed twice (2001 and 2003) - this module only implements the most recent standard. The two older Whirlpool implementations (sometimes called Whirlpool-0 (pre 2001) and Whirlpool-T (pre 2003)) were not used much anyway (both have never been recommended by NESSIE).

Usage
use ;
let mut hasher = default;
hasher.input;
let result = hasher.result;
