RustCrypto: RIPEMD

Pure Rust implementation of the RIPEMD cryptographic hash.

This crate implements only the modified 1996 versions, not the original one from 1992.

Note that RIPEMD-256 provides only the same security as RIPEMD-128, and RIPEMD-320 provides only the same security as RIPEMD-160.

Examples

use ripemd::{Ripemd160, Ripemd320, Digest};
use hex_literal::hex;

let mut hasher = Ripemd160::new();
hasher.update(b"Hello world!");
let hash160 = hasher.finalize();

assert_eq!(hash160, hex!("7f772647d88750add82d8e1a7a3e5c0902a346a3"));

// Hex-encode hash using https://docs.rs/base16ct
let hex_hash160 = base16ct::lower::encode_string(&hash160);
assert_eq!(hex_hash160, "7f772647d88750add82d8e1a7a3e5c0902a346a3");

// Same example for RIPEMD-320
let mut hasher = Ripemd320::new();
hasher.update(b"Hello world!");
let hash320 = hasher.finalize();

assert_eq!(hash320, hex!(
    "f1c1c231d301abcf2d7daae0269ff3e7bc68e623"
    "ad723aa068d316b056d26b7d1bb6f0cc0f28336d"
));
