Module cipher

This module is used for standard, typical encryption and decryption.

The data is fully loaded into memory before encryption/decryption, and it is processed within the same “block”

Examples

// obviously the key should contain data, not be an empty vec
let raw_key = Protected::new(vec![0u8; 128]);
let salt = gen_salt();
let key = balloon_hash(raw_key, &salt, &HeaderVersion::V4).unwrap();
let cipher = Ciphers::initialize(key, &Algorithm::XChaCha20Poly1305).unwrap();

let secret = "super secret information";

let nonce = gen_nonce(&Algorithm::XChaCha20Poly1305, &Mode::MemoryMode);
let encrypted_data = cipher.encrypt(&nonce, secret.as_bytes()).unwrap();

let decrypted_data = cipher.decrypt(&nonce, encrypted_data.as_slice()).unwrap();

assert_eq!(secret, decrypted_data);
