SHA-1 hash function

RustCrypto: SHA-1

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

Pure Rust implementation of the SHA-1 hash function.


🚨 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.

Minimum Supported Rust Version

Rust 1.41 or higher.

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