Acrobat 9 Pro / Files with public+private key security

Oct 24, 2009 11:38 AM



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.

    You might be able to write some JavaScript to solve the problem, but even in that case you need to be aware that the security of PDFs are not all that secure, particularly if one uses a 3rd party reader. Apparently several of them ignore the PDF security settings and open the PDF anyway. I do not know if that would occur if the PDF were encrypted in some way.


    So much for giving a spin on the topic. Good luck.

    You can create a plugin for Adobe Acrobat with your own security handler. Look for 'security handler' in the Acrobat SDK.
