RustCrypto: SHA-1

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

Pure Rust implementation of the SHA-1 cryptographic hash algorithm.

🚨 Warning: Cryptographically Broken! 🚨

The SHA-1 hash function should be considered cryptographically broken and unsuitable for further use in any security critical capacity, as it is practically vulnerable to chosen-prefix collisions.

We provide this crate for legacy interoperability purposes only.

Examples

One-shot API

use hex_literal::hex;
use sha1::{Sha1, Digest};

let result = Sha1::digest(b"hello world");
assert_eq!(result, hex!("2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"));

Incremental API

use hex_literal::hex;
use sha1::{Sha1, Digest};

let mut hasher = Sha1::new();
hasher.update(b"hello world");
let hash = hasher.finalize();

assert_eq!(hash, hex!("2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"));

Also, see the examples section in the RustCrypto/hashes readme.

Minimum Supported Rust Version

Rust 1.72 or higher.

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