jeslxdev/password-scrambler
===========================

[](#jeslxdevpassword-scrambler)

Concise, production-focused PHP library for reversible, time-boxed password tokenization and secure password storage.

What this library provides

- Deterministic reversible "scrambling" of password strings: Base64 encode -> deterministic shuffle -> AEAD (XChaCha20-Poly1305).
- Time-boxed keys with TTL and grace window for key rotation.
- Compact, versioned token format (base64url JSON payload).
- Argon2id password hashing for long-term storage (recommended).
- A small PDO-backed repository to persist scrambled tokens without requiring callers to write SQL.

Requirements

- PHP >= 8.4
- ext-sodium
- ext-json
- PDO + appropriate driver for your DB (SQLite or MySQL supported by repository code)

Quick usage

1. Create key descriptor and key store

```
use JeslxDev\PasswordScrambler\KeyStore\KeyDescriptor;
use JeslxDev\PasswordScrambler\KeyStore\InMemoryKeyStore;

$master = random_bytes(32);
$kid = substr(bin2hex(sodium_crypto_generichash($master, '', 16)), 0, 8);
$desc = new KeyDescriptor($kid, base64_encode($master), time(), 86400);
$store = new InMemoryKeyStore([$desc]);
```

2. Encrypt / decrypt

```
use JeslxDev\PasswordScrambler\Cipher\PasswordCipher;
use JeslxDev\PasswordScrambler\Cipher\CipherConfig;

$cipher = new PasswordCipher($store, new CipherConfig());
$token = $cipher->encrypt('my-plain-password');
$plain = $cipher->decrypt($token);
```

3. Store tokens with PasswordManager (optional)

```
use JeslxDev\PasswordScrambler\Storage\DBConfig;
use JeslxDev\PasswordScrambler\Storage\Database;
use JeslxDev\PasswordScrambler\Service\PasswordManagerFactory;

$db = new Database(new DBConfig('sqlite:/path/to/file.db'));
$manager = PasswordManagerFactory::createFromDbAndKeyStore($db, $store);
$manager->store('user-id', 'my-plain-password');
```

Migration

- A minimal migration helper is available at `bin/migrate.php`. It creates a `user_passwords` table for SQLite or MySQL.
- For production use, prefer a dedicated migration tool (Phinx, Doctrine Migrations, Flyway, etc.).

Security notes

- Never commit master key material. Keep keys in an HSM or a secrets manager when possible.
- The reversible token is intended for workflows that need restoration for a limited time; prefer one-way hashing (Argon2id) when possible.

Testing

- Unit tests: PHPUnit. An integration test uses SQLite in-memory and will be skipped if the PDO sqlite driver is not present.
