Pure Rust implementation of the SKIPJACK cipher.
SKIPJACK is a broken and outdated cipher. This implementation should be used for educational purposes ONLY. It should NEVER be used in a production environment and the author WILL NOT take on responsibility for damage caused by irresponsible usage of this library!
USE AT YOUR OWN RISK!
This crate implements the low-level cipher functions of the SkipJack cipher. It supports a better optimized encryption/decryption of 64-bit blocks than the approach specified by the original SkipJack specification.
There are benchmarks available in /benches/.
rust

let mut buf = [0x3322, 0x1100, 0xddcc, 0xbbaa].into();
skipjack.encrypt(&mut buf);
