Hi folks, I have Given a task to make a application installation using key. The installation file is ready I have to just add the Registration key feature. I have to do following task. 1. when user gives the url a installation page apears. when he clicks on user agree terms, it goes to then next page where he give information about database and other stuff with the registration key. 2. If the registration key goes to the company's site and checks for authetication and if they have bought the product or not. can any one tell me how do i go about this? and also how do will make these code unreadable so that user could not manuplate the code. get access without registration.

I don't know HOW to do it, but I think I know the concept and maybe that would be enough to get you started? Basically, you need to throw in some salt. Some random, but unique piece of info that is not stored as part of the original key to help authenticate it... Now that I'm typing this out I'm not sure I do understand the concept completely hehehe :) Look at adding salt, maybe something from the database, or something else that you can control. -- Jason Pruim Raoset Inc.
