* This interface adds a method for getting a salt based on a username. The
34
* reason for this is that before you the user has been added to the database
35
* you only have the username to base the salt on. The alternative is to add the
36
* user to database first and then encode and set the password later, but then
37
* we need a User to UserDetails converter.
