# RustCrypto: Skein

Implementation of the [Skein] family of cryptographic hash algorithms.

There are 3 standard versions of the Skein hash function: `Skein256`, `Skein512`, `Skein1024`.

Output size of the Skein hash functions is arbitrary, so it has to be
fixed using additional type parameter.

## Examples

```rust
use hex_literal::hex;
use skein::{Digest, Skein512_256};

let mut hasher = Skein512_256::new();
hasher.update(b"The quick brown fox ");
hasher.update(b"jumps over the lazy dog");
let hash = hasher.finalize();

assert_eq!(hash, hex!("b3250457e05d3060b1a4bbc1428bc75a3f525ca389aeab96cfa34638d96e492a"));
```

See the [`digest`] crate docs for additional examples.
