RustCrypto: OCB3
Pure Rust implementation of the Offset Codebook Mode v3 (OCB3) Authenticated Encryption with Associated Data (AEAD) cipher as described in RFC7253.
Example
use aes::Aes128;
use ocb3::{
aead::{Aead, AeadCore, KeyInit, OsRng, generic_array::GenericArray},
consts::U12,
Ocb3,
};
type Aes128Ocb3 = Ocb3<Aes128, U12>;
let key = Aes128::generate_key(&mut OsRng);
let cipher = Aes128Ocb3::new(&key);
let nonce = Aes128Ocb3::generate_nonce(&mut OsRng);
let ciphertext = cipher.encrypt(&nonce, b"plaintext message".as_ref()).unwrap();
let plaintext = cipher.decrypt(&nonce, ciphertext.as_ref()).unwrap();
assert_eq!(&plaintext, b"plaintext message");
