The preferred method of installation is via Packagist and Composer. Run the following command to install the package and add it as a requirement to your project's composer.json:
composer require frowhy/authenticationuse Frowhy\Authentication\Authentication;
require_once __DIR__ . '/vendor/autoload.php';
header('Content-type: application/json');
$str = 'aaa';
$salt = 'bbb';
$make = Authentication::make($str, $salt);
$state = Authentication::verify($make);
$sign = Authentication::get($make, $salt);
echo json_encode(['make' => $make, 'state' => $state, 'sign' => $sign]);
