But the thing is that I will ask the user for user name and password
only once i.e. when they start the application for the first time.
After that, I'm not supposed to ask the user name and password again.
So in this scenario, if I store a hash on the disk I cannot retrieve
plain-text string back from my hash as I've to send user name and
password to the server in plain-text.
