Crate shake 

RustCrypto: SHAKE

Implementation of the SHAKE family of extendable-output functions (XOFs) defined in NIST FIPS 202.

Examples

SHAKE functions have an extendable output, so finalization methods return XOF reader from which results of arbitrary length can be read.

use shake::Shake128;
use shake::digest::{Update, ExtendableOutput, XofReader};
use hex_literal::hex;

let mut hasher = Shake128::default();
hasher.update(b"abc");
let mut reader = hasher.finalize_xof();
let mut buf = [0u8; 10];
reader.read(&mut buf);
assert_eq!(buf, hex!("5881092dd818bf5cf8a3"));
reader.read(&mut buf);
assert_eq!(buf, hex!("ddb793fbcba74097d5c5"));

See the digest crate docs for additional examples.
