//! AES block cipher constant-time implementation. //! //! The `aes-soft` crate implements the AES algorithm completely in software //! without using any table lookups or other timing dependant mechanisms. //! The implementation is heavily based on `aessafe` [module][1] //! from `rust-crypto` crate. //! //! # Usage example //! ``` //! use aes_soft::block_cipher_trait::generic_array::GenericArray; //! use aes_soft::block_cipher_trait::BlockCipher; //! use aes_soft::Aes128; //! //! let key = GenericArray::from_slice(&[0u8; 16]); //! let mut block = GenericArray::clone_from_slice(&[0u8; 16]); //! let mut block8 = GenericArray::clone_from_slice(&[block; 8]); //! // Initialize cipher //! let cipher = aes_soft::Aes128::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); //! //! // We can encrypt 8 blocks simultaneously using //! // instruction-level parallelism //! let block8_copy = block8.clone(); //! cipher.encrypt_blocks(&mut block8); //! cipher.decrypt_blocks(&mut block8); //! assert_eq!(block8, block8_copy); //! ``` //!
