Different hardware-locked keys in the same publication

I´m publicating an 8-module .exe file. Each module is independent from the others and sold independently. How is it possible to make one hardware-locked key for each module (so I can permit the end-user to acces individual modules while the others remain locked) and a global key (to acess all the modules at the same time)?

It’s possible thanks to certificates. You should create a global registered certificate available in all of your 8 modules (with the same certificate ID) and another registered certificate with a different certificate ID for each module.

Thanks for your reply. I still have a few questions: 1) Should I select the option “add unlock program” for each certificate? 2) What about nag screen at startup? How to configure the security profiles (condition: always; condition: trial mode; condition: registered mode; condition: following certificate active)? 4) In the end, I go to “file properties” and connect the opening file of each module to the correct security profile, right? Please, forgive me for making so many questions and Thanks a lot.
