SHA1 is not exactly a good choice for crypto hashes these days but unfortunately SHA1 continues to be needed for a handful of situations due to legacy functionality. If you have the need for a SHA1 implementation that does not pull in large dependency chains you might want to consider this crate. In all other cases use the new [`sha1`](https://crates.io/crates/sha1) crate by the RustCrypto project instead. ## sha1 crate This crate used to be published as `sha1` but in recent years a large ecosystem of hash libraries was built around [`RustCrypto`](https://github.com/RustCrypto) so the crate name was given to that project instead. Versions newer than `0.6` of `sha1`. This is largely based on the hash code in crypto-rs by Koka El Kiwi. ## License and Links - [Documentation](https://docs.rs/sha1-smol/) - [Issue Tracker](https://github.com/mitsuhiko/sha1-smol/issues) - License: [3 Clause BSD](https://github.com/mitsuhiko/sha1-smol/blob/master/LICENSE)
