Pure Rust implementation of the BLAKE2 hash function family.
use blake2::{Blake2b512, Blake2s256, Digest}; use hex_literal::hex; // create a Blake2b512 object let mut hasher = Blake2b512::new(); // write input message hasher.update(b"hello world"); // read hash digest and consume hasher let hash = hasher.finalize(); assert_eq!(hash, hex!( "021ced8799296ceca557832ab941a50b4a11f83478cf141f51f933f653ab9fbc" "c05a037cddbed06e309bf334942c4e58cdf1a46e237911ccd7fcf9787cbc7fd0" )); // same example for Blake2s256: let mut hasher = Blake2s256::new(); hasher.update(b"hello world"); let hash = hasher.finalize(); assert_eq!(hash, hex!("9aec6806794561107e594b1f6a8a6b0c92a0cba9acf5e5e93cca06f781813b0b"));See the digest crate docs for additional examples.
This implementation supports output sizes variable at compile time:
use blake2::{Blake2b, Digest, digest::consts::U10}; use hex_literal::hex; type Blake2b80 = Blake2b<U10>; let mut hasher = Blake2b80::new(); hasher.update(b"my_input"); let res = hasher.finalize(); assert_eq!(res, hex!("2cc55c84e416924e6400"));The crate is licensed under either of:
