Installation and documentation
------------------------------

[](#installation-and-documentation)

- Available as [Composer](http://getcomposer.org/) package [eloquent/lockbox](https://packagist.org/packages/eloquent/lockbox).
- [API documentation](http://lqnt.co/lockbox-php/artifacts/documentation/api/) available.

What is *Lockbox*?
------------------

[](#what-is-lockbox)

*Lockbox* is the simplest possible way to implement strong encryption for use in applications. *Lockbox* uses a combination of well-established technologies to ensure the safety of data. For more information, see the [Lockbox website](http://lqnt.co/lockbox).

Usage
-----

[](#usage)

### Generating and writing keys

[](#generating-and-writing-keys)

```
use Eloquent\Lockbox\Key\Generator\KeyGenerator;
use Eloquent\Lockbox\Key\Persistence\KeyWriter;

$keyGenerator = new KeyGenerator;
$key = $keyGenerator->generateKey();

$keyPath = '/path/to/lockbox.key';
$keyWriter = new KeyWriter;
$keyWriter->writeFile($key, $keyPath);
```

Currently there is no way to generate lockbox keys via the command line, but this feature is planned.

### Encrypting data

[](#encrypting-data)

```
use Eloquent\Lockbox\Encrypter;
use Eloquent\Lockbox\Key\Persistence\KeyReader;

$keyPath = '/path/to/lockbox.key';
$keyReader = new KeyReader;
$key = $keyReader->readFile($keyPath);

$encrypter = new Encrypter;
echo $encrypter->encrypt($key, 'Super secret data.');
```

### Encrypting multiple data packets with the same key

[](#encrypting-multiple-data-packets-with-the-same-key)

*Lockbox* includes 'bound' encrypters that are locked to a particular key, which are convenient for encrypting multiple data packets.

```
use Eloquent\Lockbox\Bound\BoundEncrypter;
use Eloquent\Lockbox\Key\Persistence\KeyReader;

$keyPath = '/path/to/lockbox.key';
$keyReader = new KeyReader;
$key = $keyReader->readFile($keyPath);

$encrypter = new BoundEncrypter($key);

echo $encrypter->encrypt('Super secret data.');
echo $encrypter->encrypt('Extra secret data.');
echo $encrypter->encrypt('Mega secret data.');
```

### Decrypting data

[](#decrypting-data)

```
use Eloquent\Lockbox\Decrypter;
use Eloquent\Lockbox\Key\Persistence\KeyReader;

$keyPath = '/path/to/lockbox.key';
$keyReader = new KeyReader;
$key = $keyReader->readFile($keyPath);

$decrypter = new Decrypter;

$encrypted =
    'AQF_VjJS9sAL75uuUP_HTu9Do_3itIDaHLLXmh_JLOBRqQeZ_hnDwht4WtEkz3io' .
    'iW0WIHb3lANyKqpShyiPcVdj_DbfYiIPEWab8e3vqwEUvoqFFNo';

$result = $decrypter->decrypt($key, $encrypted);
if ($result->isSuccessful()) {
    echo $result->data();
} else {
    echo 'Decryption failed.';
}
```

    'dk_s0FWZ7NYFjSDt1puIrr7MlB7owNuR5KhUIj04Can0zDCYjJY',
);

foreach ($encrypted as $string) {
    $result = $decrypter->decrypt($string);
    if ($result->isSuccessful()) {
        echo $result->data();
    } else {
        echo 'Decryption failed.';
    }
}
```
