I need a class that securely implements a trial version system where you can limit the application to either a certain number of executions, or a number of days before it expires.
## Deliverables
The class needs to have a very straightforward user interface, all the dirty work should be taken care of behind the scenes. It needs to save the information very securely, so that not even a good computer user can find understand it. Of course no sollution is bulletproof, but it needs to be as secure as is ever possible. In trial day mode it needs to make sure that the user hasn't fiddled with the system clock, or done anything else for that matter to break the protection scheme.
The code needs to compile on MinGw for Windows.
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done.
2) Deliverables must be in ready-to-run condition, as follows? (depending on the nature? of the deliverables):
a)? For web sites or? other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment.
b) For all others including desktop software or software the buyer intends to distribute: A software? installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request.
3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement).
