plain-aes  

An implementation of Rijndael's cipher, commonly known as Advanced Encryption Standard.

Features

• Based on FIPS 197 Final.
• Thoroughly tested and documented.
• Implements AES-128/192 encryption and decryption.
• Implements the following modes of operation:
  • Electronic CodeBook.
  • Cipher Block Chaining.
• Ability to implement your own mode of operation, using the block operations exposed by the crate's internal module.
• Out of the box support for &[str] and &[u8] encryption/decryption.
• Ability to encrypt/decrypt any custom data structure that implements the Encryptable trait.

Usage

To use the crate, either add plain-aes to your Cargo.toml's dependecies, or run cargo add plain-aes.
Here's a quick example on how to encrypt a text message in AES128-ECB:

use plain_aes::{encrypt, ModeOfOperation, CipherVersion};
let message = "This is a super secret message";
let key = "This lib is cool"; // This lib is cool
let encrypted_message = encrypt(message, CipherVersion::Aes128(key.as_bytes(), ModeOfOperation::ECB)).unwrap();
let expected_enrypted: &[u8] = &[
   0x11, 0x2B, 0xBD, 0x0D, 0x4C, 0x0C, 0xC5, 0x02, 0xB4, 0xC1, 0x38, 0xFD, 0x9A, 0x56,
    0xC1, 0xA8, 0x78, 0x61, 0xD9, 0xF5, 0x6B, 0x48, 0xCC, 0xC5, 0x48, 0x14, 0xF2, 0x8C,
    0x1A, 0x25, 0x11, 0xA3,
];
assert!(expected_enrypted.iter().eq(encrypted_message.iter()))
