# RustCrypto: Whirlpool

Pure Rust 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
crate 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).

For details see this [page][1].

## Examples

```rust
use whirlpool::{Whirlpool, Digest};
use hex_literal::hex;

let mut hasher = Whirlpool::new();
hasher.update(b"Hello Whirlpool");
let hash = hasher.finalize();

assert_eq!(hash, hex!(
    "8eaccdc136903c458ea0b1376be2a5fc9dc5b8ce8892a3b4f43366e2610c206c"
    "a373816495e63db0fff2ff25f75aa7162f332c9f518c3036456502a8414d300a"
));
```
