The NzoUrlEncryptorBundle is a Symfony Bundle used to Encrypt and Decrypt data and variables in the Web application or passed through the URL to provide more security to the project. Also it prevent users from reading and modifying sensitive data sent through the URL.

Features include:

• Compatible Symfony version 2, 3 & 4
• Url Data & parameters Encryption
• Url Data & parameters Decryption

Installation

Through Composer:

Install the bundle:

$ composer require nzo/url-encryptor-bundle

Register the bundle in app/AppKernel.php (Symfony V2 or V3):

// app/AppKernel.php

public function registerBundles()
{
    return array(
        // ...
        new Nzo\UrlEncryptorBundle\NzoUrlEncryptorBundle(),
    );
}

Configure your application's config.yml:

Configure your secret encryption key:

# app/config/config.yml (Symfony V2 or V3)
# config/packages/nzo_url_encryptor.yaml (Symfony V4)

nzo_url_encryptor:
    secret_key: YourSecretEncryptionKey    # optional, max length of 100 characters.
    secret_iv:  YourIvEncryptionKey        # optional, max length of 100 characters.
    cipher_algorithm:                      # optional, default: 'aes-256-ctr'

Usage

In the twig template:

Use the twig extensions filters or functions to encrypt or decrypt your data:

// Filters:

# Encryption:

    <a href="{{path('my-route', {'id': myId | urlencrypt } )}}"> My link </a>

    {{myVar | urlencrypt }}

# Decryption:

    <a href="{{path('my-route', {'id': myId | urldecrypt } )}}"> My link </a>

    {{myVar | urldecrypt }}


// Functions:

# Encryption:

    <a href="{{path('my-path-in-the-routing', {'id': nzoEncrypt('myId') } )}}"> My link </a>

    {{ nzoEncrypt(myVar) }}

# Decryption:

    <a href="{{path('my-path-in-the-routing', {'id': nzoDecrypt('myId') } )}}"> My link </a>

    {{ nzoDecrypt(myVar) }}

In the controller with annotation service:

Use the annotation service to decrypt / encrypt automatically any parameter you want, by using the ParamDecryptor / ParamEncryptor annotation service and specifying in it all the parameters to be decrypted/encrypted.

use Nzo\UrlEncryptorBundle\Annotations\ParamDecryptor;
//...

    /**
     * @ParamDecryptor(params={"id", "bar"})
     */
     public function indexAction($id, $bar)
    {
        // no need to use the decryption service here as the parameters are already decrypted by the annotation service.
        //...
    }
    
    
    
    use Nzo\UrlEncryptorBundle\Annotations\ParamEncryptor;
    //...
    
        /**
         * @ParamEncryptor(params={"id", "bar"})
         */
         public function indexAction($id, $bar)
        {
            // no need to use the encryption service here as the parameters are already encrypted by the annotation service.
            //...
        }

In the controller without annotation service:

Use the decrypt function of the service to decrypt your data:

     public function indexAction($id) 
    {
        $myId = $this->get('nzo_url_encryptor')->decrypt($id);

        //...
    }

You can also use the encrypt function of the service to encrypt your data:

     public function indexAction() 
    {   
        //...
        
        $encrypted = $this->get('nzo_url_encryptor')->encrypt($data);
        //...
    }
