Crate shabal

Expand description

An implementation of the Shabal cryptographic hash algorithm.

There are 5 standard algorithms specified in the Shabal standard:

Shabal192, which is the Shabal algorithm with the result truncated to 192 bits
Shabal224, which is the Shabal algorithm with the result truncated to 224 bits
Shabal256, which is the Shabal algorithm with the result truncated to 256 bits.
Shabal384, which is the Shabal algorithm with the result truncated to 384 bits.
Shabal512, which is the Shabal algorithm with the result not truncated.

There is a single Shabal algorithm. All variants have different initialisation and apart from Shabal512 all truncate the result.

Usage

use hex_literal::hex;
use shabal::{Shabal256, Digest};

// create a Shabal256 hasher instance
let mut hasher = Shabal256::new();

// process input message
hasher.update(b"helloworld");

// acquire hash digest in the form of GenericArray,
// which in this case is equivalent to [u8; 32]
let result = hasher.finalize();
assert_eq!(result[..], hex!("
