Hi All
Does anyone know how to secure ASP application by use of keys. I have three security key related issues:
1. to be able to provide a trial version for ASP applications
2. To be be able to provide valid key when the customer pays for the license
3. To provide annual license lock pending renewal for ASP applications
Any clue is highly appreciated
Regards

if they host it, you will have to give them the source - once that is done anything you put in place can be taken out/hacked. The only way to do this is host the app yourself and sell it as a SAAS or hosted solution. Where they dont have access to the app itself - just the front end.

You can create a DLL, register it on Client's Server, store some application business logic in that DLL and validate an external license file, provided by vendor (you), from this DLL.
License expiration, trial product functionality, etc. can be controlled from this DLL.

@v, given you
1) hide a lot of logic that they cant replicate from taking the code apart
2) and there ISP allows unverified dlls to be installed on their servers

Thanks all. How do I go about creating such a DLL or hide the code?
