**Note: Skipjack is not suitable for contemporary use. This library exists as an example,

and not for consumption.**

skipjack.rs is a straight-line (meaning no branches or loops) Rust implementation of the

[Skipjack](https://en.wikipedia.org/wiki/Skipjack_(cipher)) cipher,

best known for its use by the NSA in the [Clipper chip](https://en.wikipedia.org/wiki/Clipper_chip).

skipjack.rs has three primary goals (all for educational purposes, for yours truly):

1. To represent safe, idiomatic Rust in a cryptographic context

2. To be easy to read and understand with a minimal understanding of Rust,

even without a background in cryptography

3. To directly reflect the NIST specification for Skipjack (i.e., no optimizations or shortcuts)

## Design

This implementation attempts to adhere closely to the

[NIST-provided specification](https://csrc.nist.gov/CSRC/media/Projects/Cryptographic-Algorithm-Validation-Program/documents/skipjack/skipjack.pdf)

in design, and does not support any modes of operation other than single-block

[codebook](https://en.wikipedia.org/wiki/Block_cipher_mode_of_operation#Electronic_Codebook_(ECB)).

## Installation

You should not use Skipjack (or skipjack.rs) for anything serious. But, if you'd like to play

with it, you can install it via `cargo`:

```toml

[dependencies]

skipjack = "0.1.0"

```

Documentation is available on [docs.rs](https://docs.rs/crate/skipjack).
