//! ```
//! extern crate aes;
//! extern crate fpe;
//!
//! use aes::Aes256;
//! use fpe::ff1::{BinaryNumeralString, FF1};
//!
//! let key = [0; 32];

//!
//! let ff = FF1::<Aes256>::new(&key, radix).unwrap();
//! let ct = ff.encrypt(&[], &BinaryNumeralString::from_bytes_le(&pt)).unwrap();
//! assert_eq!(ct.to_bytes_le(), [0x75, 0xfb, 0x62]);
//!
//! let p2 = ff.decrypt(&[], &ct).unwrap();
//! assert_eq!(p2.to_bytes_le(), pt);
