PierrreEncrypterBundle

PierrreEncrypterBundle provides easy to use encryption service in Symfony2.

Features

• A service you can call from PHP code
• A Twig extension (optional)
• 100% unit testing!

Prerequisites

Make sure PHP Mcrypt extension is installed.

Do not use in production

This library is not meant for production use (as such has no stable tags). It has not been vetted by a cryptography expert.

Installation

This installation procedure is intended for use with Symfony2, but you can adapt it with submodules.

Step 1: Download the bundle

Add the following lines in your deps file:

[PierrreEncrypterBundle]
    git=http://github.com/pierrre/PierrreEncrypterBundle.git
    target=/bundles/Pierrre/EncrypterBundle

Now, run the vendors script to download the bundle:

php bin/vendors install

Step 2: Configure the Autoloader

Add the Pierrre namespace to your autoloader:

<?php
// app/autoload.php
$loader->registerNamespaces(array(
    // ...
    'Pierrre' => __DIR__.'/../vendor/bundles',
));

Step 3: Enable the bundle

Finally, enable the bundle in the kernel:

<?php
// app/AppKernel.php
public function registerBundles()
{
    $bundles = array(
        // ...
        new Pierrre\EncrypterBundle\PierrreEncrypterBundle(),
    );
}

Configuration

This is the default configuration, all values are optional:

# app/config.yml
pierrre_encrypter:
    encrypters: #Encrypters list, requires at least one encrypter.
        my_encrypter: #Encrypter name
            key: "@kernel.secret" #The secret that is used to encrypt data. By default, it will use the kernel secret.
            algorithm: "rijndael-128" #Encryption algorithm
            mode: "cbc" #Encryption mode
            random_initialization_vector: true #If you set it to false, it will use a blank string as initialization vector.
            base64: true #Encode the encrypted data with the base64 algorithm.
            base64_url_safe: true #Replace "+" and "/" characters by "-" and "_".
    twig: #Twig extension
        enabled: false #Enable extension
        default_encrypter: null #Default encrypter. By default, it's the first encrypter

Please read the Mcrypt documentation.

Usage

Please note:

• If a random initialization vector is used, it will be concatenated at the beginning of the encrypted data.
• "\0" characters at the end of the decrypted data will be removed.
• "=" characters at the end of the encrypted+base64 data will be removed.

Programmatically

With dependency injection container

<?php
$encrypter = $container->get('pierrre_encrypter.manager')->get('my_encrypter');
$data = 'foobar';
$encryptedData = $encrypter->encrypt($data);
$decryptedData = $encrypter->decrypt($encryptedData);

Manually

<?php
use Pierrre\EncrypterBundle\Util\Encrypter;
$encrypter = new Encrypter(array('key' => 'mySecret'));

Twig extension

{{ data | encrypt }}
{{ data | encrypt('my_encrypter') }}
