Pure Rust implementation of the SHA-1 cryptographic hash algorithm.
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.
If possible use the sha1-checked crate, while slower it provides the ability to detect potential collisions, as well as generate alternative safe hashes.
use hex_literal::hex;
use sha1::{Sha1, Digest};
let result = Sha1::digest(b"hello world");
assert_eq!(result, hex!("2aae6c35c94fcfb415dbe95f408b9ce91ee846ed"));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.
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.
