" previous version of this class was intended for use in a much larger project (I will be publishing articles on various components of that project soon.).

The PasswordGenerator class is fairly simple. Auto-creation of passwords according to a specified rule.Registration/membership systems for Web sites.Password generators are useful in many applications:
