libaes

This is a re-implementation of AES in safe Rust, with zero dependencies. The core algorithm is ported from AES core in OpenSSL 1.1.1 stable. This library strives to be:

• Correct (as the original OpenSSL implementation)
• Fast (as OpenSSL 1.1.1)
• Safe Rust code only.
• Small: no dependencies.

Currently, this library supports 128-bit, 192-bit and 256-bit keys with CBC mode and CFB128 mode.

Examples

use libaes::Cipher;

let my_key = b"This is the key!"; // key is 128-bit (16 bytes)
let plaintext = b"A plaintext";
let iv = b"This is 16 bytes";

// Create a new cipher
let cipher = Cipher::new_128(my_key);

// Encryption
let encrypted = cipher.cbc_encrypt(iv, plaintext);

// Decryption
let decrypted = cipher.cbc_decrypt(iv, &encrypted[..]);

Correctness

We use the test data in NIST Special Publication 800-38A to verify the cipher, see the test code.
