Pass the hashed password to Java Mail API

Good morning everybody,

I am developing ERP for my company using GWT Framework and I am getting the number of unread emails using Java Mail API. I can do this, but the problem is that I store the SHA-512 hashed password on the databases and I would not pass the clear Java Mail API password, but just hashed the password to avoid passing the cleared password over the network.

I am using this code to get the number of unread emails:

private static int getNumberOfUnreadMails() {
   int numberOfUnreadMails = 0;

    Properties properties = new Properties();
    properties.put("mail.imap.host", "myserver.com");
    properties.put("mail.imap.user", "developper@myserver.com");
    properties.put("mail.imap.socketFactory", 143);
    properties.put("mail.imap.socketFactory.class", "java.net.ssl.SSLSocketFactory");
    properties.put("mail.imap.port", 143);
    Session session = Session.getDefaultInstance(properties, new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication("developper@myserver.com", "mypassword");
        }
    });
    Store store;
    try {
        store = session.getStore("imap");
        store.connect();
        Folder folder = store.getFolder("Inbox");
           numberOfUnreadMails = folder.getUnreadMessageCount();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return numberOfUnreadMails;
}

      

        
        
        
      

    

I can also use a different hashing algorithm. If you know the solution to my problem, pounce on it in advance.
