RustCrypto: MD5

Pure Rust implementation of the MD5 cryptographic hash algorithm.

⚠️ Security Warning

This crate is provided for the purposes of legacy interoperability with protocols and systems which mandate the use of MD5.

However, MD5 is cryptographically broken and unsuitable for further use.

Collision attacks against MD5 are both practical and trivial, and theoretical attacks against MD5's preimage resistance have been found.

RFC 6151 advises no new IETF protocols can be designed MD5-based constructions, including HMAC-MD5.

Examples

use md5::{Md5, Digest};
use hex_literal::hex;

let mut hasher = Md5::new();
hasher.update(b"hello world");
let hash = hasher.finalize();

assert_eq!(hash, hex!("5eb63bbbe01eeed093cb22bb8f5acdc3"));

See the digest crate docs for additional examples.
