Usage Example :

use RiskySetiawan\SSODecoder\JWTToken;

// Data payload
$payload = [
    'user_id' => 123,
    'email' => 'user@example.com',
];

// Secret key (harus sama di semua aplikasi yang pakai package ini)
$secret = 'your-very-secret-key';

// Enkripsi payload jadi token terenkripsi (JWT + AES256)
// Function urldecode in payload is very important not change !
$encryptedToken = JWTToken::encrypt(urldecode($payload), $secret);

// Kirim $encryptedToken ke aplikasi lain, atau simpan di client

// Dekripsi token kembali ke payload array
$decryptedPayload = JWTToken::decrypt($encryptedToken, $secret);

print_r($decryptedPayload);

/*

    'user_id' => 123,
