        String hostname = "hostname";
        SSLSocketFactory factory = HttpsURLConnection.getDefaultSSLSocketFactory();
        SSLSocket socket = (SSLSocket)factory.createSocket(hostname, port);
    
        // Connect to the server
        socket.startHandshake();
    
        // Retrieve the server's certificate chain
        java.security.cert.Certificate[] serverCerts =
            socket.getSession().getPeerCertificates();
    
        // Close the socket
        socket.close();
    } catch (SSLPeerUnverifiedException e) {
