Crate magma

Implementation of the block cipher defined in GOST 28147-89 and GOST R 34.12-2015.

Examples

use magma::{Magma, BlockCipher, BlockEncrypt, BlockDecrypt, NewBlockCipher};
use magma::cipher::generic_array::GenericArray;
use hex_literal::hex;

// Example vector from GOST 34.12-2018
let key = hex!("
    FFEEDDCCBBAA99887766554433221100
    F0F1F2F3F4F5F6F7F8F9FAFBFCFDFEFF
");
let plaintext = hex!("FEDCBA9876543210");
let ciphertext = hex!("4EE901E5C2D8CA3D");

let cipher = Magma::new(GenericArray::from_slice(&key));

let mut block = GenericArray::clone_from_slice(&plaintext);
cipher.encrypt_block(&mut block);
assert_eq!(&ciphertext, block.as_slice());

cipher.decrypt_block(&mut block);
assert_eq!(&plaintext, block.as_slice());

Re-exports

pub use cipher;
