RustCrypto: Shabal

crate Docs Apache2/MIT licensed Rust Version Project Chat Build Status

Pure Rust implementation of the Shabal cryptographic hash algorithm.

Documentation

About

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 shabal::{Shabal256, Digest};

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

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

// acquire hash digest in the form of GenericArray,
// which in this case is equivalent to [u8; 32]
let result = hasher.result();
assert_eq!(result[..], hex!("d945dee21ffca23ac232763aa9cac6c15805f144db9d6c97395437e01c8595a8"));

Minimum Supported Rust Version

Rust 1.41 or higher.

Minimum supported Rust version can be changed in the future, but it will be done with a minor version bump.
