The attached ZIP file contains a demo version of a PDF security managing program.
I wish to upload PDFs that are protected with a password that will expire x days after it is first opened.
So a user won't be able to have indefinite access to my PDFs forever.
The attached program is capable of adding a password that expires on a particular date, but cannot provide the function of making the password expire a certain number of days after it is first opened.
i want someone to tweak the program so that it can encrypt PDFs with time- sensitive passwords.
My version of the program to be tweaked, A-PDF Password Security, is an unlicensed demo copy, but I will purchase a license if this project is feasible.
