README

To learn more about the crypto used in the projects, please take a look at our crypto doc.

Requirements

  • PHP >= 8.0
  • Laravel >= 8.0

Installation

  1. Install the package via composer:
composer require minvws/laravel-crypto
  1. If you are running Laravel 5.5 or higher (the package will be auto-discovered), skip this step. Find the providers array key in config/app.php and register the Laravel Crypto Service Provider:
'providers' => [
    ...
    MinVWS\Laravel\Providers\CryptoServiceProvider::class,
];

Usage

This section describes the usage of the different crypto functionalities

CMS Crypto

CMS crypto allows you to easily encrypt (and possibly decrypt) data.

Usage:

class UserController {
    
    protected CmsCryptoInterface $service;
    
    function index()
    {
        $cipherText = $this->service->encrypt('plaintext');
        return new JsonResponse(['data' => $cipherText]);        
    }
}

Sealbox Crypto

class UserController {
    
    protected SealboxCryptoInterface $service;
    
    function index()
    {
        $cipherText = $this->service->encrypt('plaintext');
        return new JsonResponse(['data' => $cipherText]);        
    }
}

Signatures

class UserController {
    
    protected SignatureCryptoInterface $service;
    
    function index()
    {
        $sig = $this->service->sign('foobar', false);
        return new JsonResponse(['signature' => $sig]);        
    }
}

Laravel HTTP Middleware

Step 1: Add to app/Http/Kernel.php:

/*/ Package Middleware /*/
    ...
    'cms_sign' => \MinVWS\Crypto\Laravel\Http\Middleware\CmsSignature::class,

Step 2: Add your middleware to your routes:

Route::middleware('cms_sign')->post(
    '/my/route',
    [RouteController::class, 'index']
);

CMS_SIGN_X509_CHAIN         Optional chain of certificates to be added to the signed data

Running tests

Tests are run based on your PHP version. On PHP7, openssl functionality that is not available, will not be tested.

Running tests when you don't have PHP8 (but have docker):

You can still test PHP8 functionality when running PHP7 by using the PHP8 docker image:

docker run -ti -w /app -v $PWD:/app php:8-cli php /app/vendor/bin/phpunit

Using code coverage on PHP8:

docker run -ti -w /app -v $PWD:/app php:8-cli phpdbg -qrr /app/vendor/bin/phpunit --coverage-html=./html
