In your repository, create a new PHP file (e.g., composer.json ) and add the following dependencies:

use Symfony\Component\Console\Command\Command; use Symfony\Component\Console\Input\InputInterface; use Symfony\Component\Console\Output\OutputInterface;

$licenseKey = md5(serialize($userData)); $output->writeln("License Key: $licenseKey");

Create a new GitHub repository for your license key system. You can name it something like "php-license-key-system".
