I'm working at a Software Company. We want to create the Help Documents for our Software in PDF.
We want to take care, that those PDF documents cannot be opened without our Software.
My idea is to certificate the PDFs with a public key and the private key is hidden in our program.
I tested a lot and read the manual, but it doesn't work.
Thanx for some hints.
Sorry for the lousy English, I'm from Germany.
So much for giving a spin on the topic. Good luck.
