SSL socket php code needs to be converted to Java

I have a Pem file that I use with this php code to connect to a c++ SSL server, but now I need this php code written in Java

$ctx = stream_context_create();

stream_context_set_option($ctx, 'ssl', 'local_cert', 'cert.pem');

stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);

$fp = stream_socket_client('ssl://serverURL', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

if (!$fp) {

    print "Failed to connect $err $errstr\n";
    return;
}

Any ideas how to read in the cert.pem file in Java and then establish the SSL socket?

Thank you!

• You will need Bouncy Castle in your classpath.

  PEMReader pr = new PEMReader(new FileReader("cert.pem"));
  X509Certificate cert = (X509Certificate) pr.readObject();
  PEMReader kr = new PEMReader(new FileReader("privkey.pem"),
          new PasswordFinder() {
      public char[] getPassword() {
          return "passphase".toCharArray();
      }
  });
  KeyPair key = (KeyPair) kr.readObject();
  KeyStore ksKeys = KeyStore.getInstance("JKS");
  ksKeys.load(null, "passphase".toCharArray());
  ksKeys.setCertificateEntry("MyCert", cert);
  ksKeys.setKeyEntry("Mykey", key.getPrivate(),
          "passphase".toCharArray(), new Certificate[]{cert});
  KeyManagerFactory kmf = KeyManagerFactory.getInstance(
          KeyManagerFactory.getDefaultAlgorithm());
  kmf.init(ksKeys, "passphase".toCharArray());
  TrustManagerFactory tmf = TrustManagerFactory.getInstance(
          TrustManagerFactory.getDefaultAlgorithm());
  tmf.init(ksKeys);
  
  SSLContext sslContext = SSLContext.getInstance("TLS");
  sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
  
  Socket socket = sslContext.getSocketFactory().createSocket(
          "localhost", 4433);
  BufferedReader in = new BufferedReader(new InputStreamReader(
          socket.getInputStream()));
  PrintWriter out = new PrintWriter(new OutputStreamWriter(
          socket.getOutputStream()));
  out.println("Hello World");
  System.out.println(in.readLine());
  out.close();
  in.close();
  

  If you run openssl s_server -Verify cert.pem -cert cert.pem -key privkey.pem, it should show:

  depth=0 /C=AU/ST=Some-State/O=Internet Widgits Pty Ltd
  verify error:num=18:self signed certificate
  verify return:1
  depth=0 /C=AU/ST=Some-State/O=Internet Widgits Pty Ltd
  verify return:1
