Module aead 

Authenticated Encryption with Associated Data (AEAD) with operation pattern

This module provides implementations of authenticated encryption algorithms with an ergonomic operation pattern for operations.

Example usage

use dcrypt_algorithms::aead::{ChaCha20Poly1305Cipher, AeadCipher, AeadEncryptOperation, AeadDecryptOperation};
use rand::rngs::OsRng;

// Generate key and nonce
let key = ChaCha20Poly1305Cipher::generate_key(&mut OsRng).unwrap();
let nonce = ChaCha20Poly1305Cipher::generate_nonce(&mut OsRng).unwrap();

// Create cipher instance
let cipher = ChaCha20Poly1305Cipher::new(&key).unwrap();

// Encrypt with operation pattern
let ciphertext = cipher.encrypt()
    .with_nonce(&nonce)
    .with_aad(b"additional data")
    .encrypt(b"secret message").unwrap();

// Decrypt with operation pattern
let plaintext = cipher.decrypt()
    .with_nonce(&nonce)
    .with_aad(b"additional data")
    .decrypt(&ciphertext).unwrap();

assert_eq!(plaintext, b"secret message");
