[−][src]Crate aes
This crate is a wrapper around different implementations of AES block ciphers.
Currently it uses:
aes-soft
hardware independent bit-sliced implementationaesni
implementation using AES-NI instruction set. Used for x86-64 and x86 target architectures with enabledaes
andsse2
target features (the latter is usually enabled by default).
Crate switches between implementations automatically at compile time. (i.e. it does not use run-time feature detection)
Usage example
use aes::block_cipher_trait::generic_array::GenericArray; use aes::block_cipher_trait::BlockCipher; use aes::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 = 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);
