//! CAST5 block cipher.
//!
//! Implementation according to [RFC 2144](https://tools.ietf.org/html/rfc2144).
//!
//! # Usage example
//! ```
//! use cast5::cipher::generic_array::GenericArray;
//! use cast5::cipher::{BlockCipher, BlockEncrypt, BlockDecrypt, NewBlockCipher};
//! use cast5::Cast5;
//!
//! let key = GenericArray::from_slice(&[0u8; 16]);
//! let mut block = GenericArray::clone_from_slice(&[0u8; 8]);
//! // Initialize cipher
//! let cipher = Cast5::new(&key);
//!
//! let block_copy = block.clone();
//! // Encrypt block in-place
//! cipher.encrypt_block(&mut block);
//! // And decrypt it back
//! cipher.decrypt_block(&mut block);
//! assert_eq!(block, block_copy);
//! ```
