//! DES(Data Encryption Standard)
//! FIPS 46-3

//!
//! # Example
//!
//! ```Rust
//! use rcrypto::{DES, Cipher};
//!
//! let cases = [
//! ([0x6e, 0x5e, 0xe2, 0x47, 0xc4, 0xbf, 0xf6, 0x51], // random
//! [0x11, 0xc9, 0x57, 0xff, 0x66, 0x89, 0x0e, 0xf0], // random
//! [0x94, 0xc5, 0x35, 0xb2, 0xc5, 0x8b, 0x39, 0x72]),
//! ];
//!
//! for ele in cases.iter() {
//! let cipher = DES::new(ele.0);
//! let (mut encrypt, mut decrypt) = (Vec::with_capacity(8), Vec::with_capacity(8));
//! cipher.encrypt(&mut encrypt, ele.1.as_ref()).unwrap();
//! cipher.decrypt(&mut decrypt, encrypt.as_slice()).unwrap();
//! }
//! ```
