Why this helps GitHub projects
For this tutorial, we will assume a standard structure common to most popular PHP licensing repositories (like PHP-License-Manager or similar projects). php license key system github install
apiUrl = $apiUrl; $this->publicKey = $publicKey; public function verify(string $licenseKey, string $domain): bool !isset($data['signature'])) return false; // Verify cryptographic signature to ensure data wasn't tampered with $signature = base64_decode($data['signature']); $isValid = openssl_verify($data['payload'], $signature, $this->publicKey, OPENSSL_ALGO_SHA256); if ($isValid === 1) $payload = json_decode($data['payload'], true); return $payload['status'] === 'success'; return false; Use code with caution. 4.
