§RustCrypto: OCB
Pure Rust implementation of OCB (RFC 7253)Authenticated Encryption with Associated Data (AEAD) cipher.
§Example
use aes::Aes128;
use ocb::{
aead::{Aead, AeadCore, KeyInit, OsRng, generic_array::GenericArray},
consts::U12,
Ocb3
};
type Aes128ocb = Ocb3<Aes128, U12>;
let key = Aes128::generate_key(&mut OsRng);
let cipher = Aes128ocb::new(&key);
let nonce = Aes128ocb::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");
§Security Notes
No security audits of this crate have ever been performed, and it has not been thoroughly assessed to ensure its operation is constant-time on common CPU architectures.

Re-exports§
pub use aead;
Modules§
- Constants used, reexported for convenience.
Structs§
- Error type.
- Struct representing a generic array -
GenericArray<T, N>
works like [T; N] - OCB3: generic over a block cipher implementation, nonce size, and tag size.
Constants§
- Max associated data.
- Max ciphertext.
- Max plaintext.
Traits§
- Authenticated Encryption with Associated Data (AEAD) algorithm core trait.
- In-place stateless AEAD trait.
- Types which can be initialized from key.
- Types which use key for initialization.
Type Aliases§
- OCB3 nonce
- OCB3 tag
