SSL client certificate authentication with Java2se html-unit

Question

I am currently using htmlunit to simulate scrapping of a web page that requires an ssl client certificate to be installed (https connection). This certificate has successfully been installed in my windows OS . On access of the given webpage via web browsers(chrome & IE), a prompt is issued to select a personal certificate that will be used . I would like to access the windows cert store preferably this personal certificate to authenticate and create a successful connection to my htmlunit client.

I have managed to research on the SunMSCAPI with Windows-MY to read the store as shown in below code.

        Provider provider = Security.getProvider("SunMSCAPI");
        KeyStore store = KeyStore.getInstance("Windows-MY", provider);
        store.load(null, null);

        Enumeration<?> aliases = store.aliases();
        while (aliases.hasMoreElements()) {
            String alias = aliases.nextElement().toString();
            if (alias.equals("mypersonalcert")) {

                Certificate[] signerKey = (Certificate[]) store
                        .getCertificateChain(alias);
                Object entry = store.getKey(alias, null);
                System.out
                        .println("cert aquired! got it");

            }
        }

How do I successfully integrate this to my htmlunit webconnection and web client instance for connection? Thanks in advance.

You could use WebClientOptions.setSSLClientCertificate(URL certificateUrl,String certificatePassword, String certificateType)

to point HTMLUnit to the client certificate of your choice.
