Ahh nice. Thanks. That's the kind of nitty gritty I've been looking for and struggling to find. I'll probably go more towards Bill's suggestion in the end, but I love getting an understanding of this low level stuff works.
I didn't understand this bit though:
> If you do not need to encrypt a payload (as in my post) then I suggest making the license be just a serial number followed by a signature on that number (maybe include a short hash of the owner name)
If anyone can link me to a tutorial on how to create these signatures and hashes, that'd be really useful.
TIA
