Pure Rust implementation of the [Blowfish block cipher][1].

## ⚠️ Security Warning: [Hazmat!][hazmat-link]

This crate does not ensure ciphertexts are authentic (i.e. by using a MAC to
verify ciphertext integrity), which can lead to serious vulnerabilities
if used incorrectly!

No security audits of this crate have ever been performed, and it has not been
thoroughly assessed to ensure its operation is constant-time on common CPU
architectures.

USE AT YOUR OWN RISK!
