RustCrypto: BelT hash

Pure Rust implementation of the BelT hash function specified in STB 34.101.31-2020.

Examples

use belt_hash::{BeltHash, Digest};
use hex_literal::hex;

let mut hasher = BeltHash::new();
hasher.update(b"hello world");
let hash = hasher.finalize();

assert_eq!(hash, hex!("afb175816416fbadad4629ecbd78e1887789881f2d2e5b80c22a746b7ac7ba88"));

// Hex-encode hash using https://docs.rs/base16ct
let hex_hash = base16ct::lower::encode_string(&hash);
assert_eq!(hex_hash, "afb175816416fbadad4629ecbd78e1887789881f2d2e5b80c22a746b7ac7ba88");
