Say that I create some modules with CRTCMOD and create a program out of them
with CRTPGM.

Can any of the functions exported from the modules be used by a third party in the same way one might use a service program? I think the answer is "not
easily", but I'm not sure.

You can do this but you have to use function pointers. You'll need to provide a means of calling your program so it returns an array of pointers to the functions you want to expose. Then your caller uses the function pointers to access the functions.

Otherwise you'll have to build a service program from the modules. You don't need to expose the key generation. The service program would validate the key on first call to any of the important functions and send an exception message if not valid. The key retrieval, validation, etc. would all be contained inside the service program.
