KeeLoq

This project is an open source pure Rust implementation of Microchip's KeeLoq proprietary encryption algorithm, used in their series of KeeLoq remote key entry (RKE) devices.

Amongst others, these devices include:

• Microchip HCS200
• Microchip HCS301
• Electronic Giant EG301

Usage example

This project literally has two methods, so using it is pretty straightforward:

Encrypt ```rust use leekoq::LeeKoq;

let plain: u32 = 0x12345678; let key: u64 = 0xCAFED00D; assert_eq!(LeeKoq::encrypt(plain, key), 0xD0FB287C); **Decrypt** rust use leekoq::LeeKoq;

let cipher: u32 = 0xD0FB287C; let key: u64 = 0xCAFED00D; assert_eq!(LeeKoq::decrypt(cipher, key), 0x12345678); ```

Keys are 64-bit integers, and cipher- and plaintexts are 32-bit integers.
