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 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.
Usage example
let key = [0u8; 16]; let mut block = [0u8; 16]; let mut block8 = [0u8; 16*8]; // Initialize cipher let cipher = aesni::Aes128::new(&key); // Encrypt block in-place cipher.encrypt(&mut block); // And decrypt it back cipher.decrypt(&mut block); assert_eq!(block, [0u8; 16]); // We can encrypt 8 blocks simultaneously using instruction-level parallelism cipher.encrypt8(&mut block8); cipher.decrypt8(&mut block8);
