I would require a assistance for the following questions :
I must implement a soft which lock an application : the use of the application is subjected to a licence. This licence is to activate by one encrypted key (its possible to use the application for one given length of time). Authorization = Authorizes the use for a number access users limited + creation of a number limited of folder into the database.
How to solve the following problem:
- How to build the code of activation (I thought of a doublet: hardware hash + a ID) ? - To control the authorizations into the database ? - How to block the software properly?
