Is it possible to add user security (an open password) to an already existing pdf file? I know how to create a pdf with security but can't seem to figure out how to add it after the fact.
Yes, it is. Use PDFTK.
Probably should have mentioned that I'm doing this all through code. Is it possible to load a PDF into the queue and then apply security?
