A pure rust implementation of the RIPEMD-128 cryptographic hash based on RustCrypto/hashes ripemd160.
use ripemd128::{Ripemd128, Digest};
// create a RIPEMD-128 hasher instance
let mut hasher = Ripemd128::new();
// process input message
hasher.input(b"abc");
// acquire hash digest in the form of GenericArray,
// which in this case is equivalent to [u8; 16]
let result = hasher.result();
// assert_eq!(result[..], hex!("c14a12199c66e4ba84636b0f69144c77"));
