Module block 

Block cipher implementations with advanced type-level guarantees

This module contains implementations of various block ciphers and related algorithms with improved type-safety through compile-time constraints.

Example usage

use dcrypt_algorithms::block::{TypedAes128, TypedCbc, BlockCipher, BlockCipherMode, CipherAlgorithm};
use rand::rngs::OsRng;

// Generate a random key and nonce
let key = TypedAes128::generate_key(&mut OsRng);
let nonce = TypedCbc::<TypedAes128>::generate_nonce(&mut OsRng);

// Create cipher and mode instances
let cipher = TypedAes128::new(&key);
let mode = TypedCbc::new(cipher, &nonce).unwrap();

// Encrypt and decrypt
let plaintext = b"secret message with padding...!!"; // Exactly 32 bytes (multiple of 16)
let ciphertext = mode.encrypt(plaintext).unwrap();
let decrypted = mode.decrypt(&ciphertext).unwrap();

assert_eq!(plaintext, &decrypted[..]);
