Crate aesni [−] [src]
AES block cipher implementation using AES-NI instruction set.
This crate does not implement any software fallback and does not
automatically check CPUID, so if you are using this crate make sure to run
software on appropriate hardware or to check AES-NI availability using
check_aesni()
function with an appropriate software fallback in case of
its unavailability.
Additionally this crate currently requires nigthly Rust compiler due to the
usage of unstable asm
and simd
features.
Ciphers functionality is accessed using BlockCipher
trait from
block-cipher-trait
crate.
Usage example
use aesni::{Aes128, BlockCipher}; 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 = aesni::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);
