Subject: Eventmachine SSLSocket Client using keystore in Ruby or Jruby

I want to move to non blocking i/o from java to eventmachine or any
evented io framework like nodejs. Here is a sample code i have from java
to create a SSLSocket client and then perform to and fro data transfer.
I want to switch to eventmachine as i have lot of headaches managing the
java code eg. detecting socket disconnection etc.

How do i create a SSLSocket client in eventmachine

public SSLSocket createSocket(String ip, int port)
{
    //Socket socket;

    try{
        KeyStore localKeyStore = KeyStore.getInstance("JKS");

        char[] localKeyStorePassword = "xxxxxxx".toCharArray();
        //localKeyStore.setCertificateEntry("", "");

        localKeyStore.load(new FileInputStream("cert/sample-keys"),
localKeyStorePassword);
        KeyManagerFactory kmf =
KeyManagerFactory.getInstance("SunX509");
        kmf.init(localKeyStore, localKeyStorePassword);
        TrustManagerFactory tmf =
TrustManagerFactory.getInstance("PKIX");
        tmf.init(localKeyStore);
        SecureRandom secureRandom = new SecureRandom();
        secureRandom.nextInt(); // Force initialisation to occur now.
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(kmf.getKeyManagers(), tmf.getTrustManagers(),
secureRandom);
        SSLSocketFactory sf = sslContext.getSocketFactory();
        return (SSLSocket)sf.createSocket(ip, port);
    }
    catch(Exception kse)
    {
        kse.printStackTrace();
        return null;
    }
}
