RustCrypto: SM3

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

Pure Rust implementation of the SM3 cryptographic hash function defined in OSCCA GM/T 0004-2012.

Examples

use sm3::{Digest, Sm3};
use hex_literal::hex;

let mut hasher = Sm3::new();
hasher.update(b"hello world");
let hash = hasher.finalize();

assert_eq!(hash, hex!("44f0061e69fa6fdfc290c494654a05dc0c053da7e5c52b84ef93a9d67d3fff88"));

// Hex-encode hash using https://docs.rs/base16ct
let hex_hash = base16ct::lower::encode_string(&hash);
assert_eq!(hex_hash, "44f0061e69fa6fdfc290c494654a05dc0c053da7e5c52b84ef93a9d67d3fff88");
