XTEA

This crate provides a Rusty implementation of the XTEA cipher, written in Rust.

This crate also provides convenience methods for ciphering and deciphering u8 slices and Read streams.

See https://en.wikipedia.org/wiki/XTEA for more information on the XTEA cipher.

Note

This crate should only be used if you're working on an existing application that uses XTEA. If you're wanting to implement an encryption or a cipher system in your project DO NOT USE THIS.

Documentation

Run the command cargo doc in the directory to generate documentation in ./target/doc/

Installation

To use this crate, add the following to your Cargo.toml:

[dependencies]
extended-tea = "0.0.0"

Example

use extended_tea::XTEA;
use byteorder::BE;

let input: Box<[u8]> = vec![10u8; 16].into_boxed_slice();

let xtea = XTEA::new([0x1380C5B5, 0x28037DF9, 0x26E314A2, 0xC57684E4]);

let encrypted = {
	let mut output = vec![0u8; input.len()].into_boxed_slice();
	xtea.encipher_u8slice::<BE>(&input, &mut output);
	output
};

let decrypted = {
	let mut output = vec![0u8; input.len()].into_boxed_slice();
	xtea.decipher_u8slice::<BE>(&encrypted, &mut output);
	output
};
assert_eq!(input, decrypted);
