Synchronous encryption algorithm "Kuznechik" (GOST R 34.12-2015, GOST R 34.13-2015)
Implementation of the block synchronous encryption algorithm "Kuznechik" in Rust lang.
Encryption modes
Struct | Title | Reduction |
---|---|---|
AlgEcb | Electronic Codebook | ЕСВ |
AlgCtr | Counter | CTR |
AlgOfb | Output Feedback | OFB |
AlgCbc | Cipher Block Chaining | СВС |
AlgCfb | Cipher Feedback | CFB |
AlgMac | Message Authentication Code | MAC |
Usage (AlgOfb):
The following example encrypts and decrypts a 64-byte data block data
using the OFB method.
Encryption by other methods is similar, in some the gamma is not required
(more details in tests.rs).
extern crate kuznechik;
use self::kuznechik::{KeyStore, Kuznechik, AlgOfb};
fn main() {
// Initialization
let password = "Kuznechik";
let data = Vec::from("Hello, World!");
let gamma = vec![
0x12, 0x34, 0x56, 0x78, 0x90, 0xab, 0xce, 0xf0, 0xa1, 0xb2, 0xc3, 0xd4, 0xe5, 0xf0, 0x01, 0x12,
0x23, 0x34, 0x45, 0x56, 0x67, 0x78, 0x89, 0x90, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19,
];
let kuz = KeyStore::with_password(password);
let mut cipher = AlgOfb::new(&kuz).gamma(gamma.clone());
// Encryption
let enc_data = cipher.encrypt(data.clone());
// Decryption
// Setting gamma again because OFB algorithm modify it during performing
cipher.set_gamma(gamma);
let dec_data = cipher.decrypt(enc_data);
// Assert
assert_eq!(data, dec_data);
}
