I've been looking for the solution for a very long time but I couldn't find a solution...
With PDFCreator (Ver. 0.9.8) I regularly create my PDFs protected from copy and modification using the special flags that are in Printer > Options > Formats > PDF > Security; When I save the PDF, after the application of the file name, a password is typed in (Owner password). Well, there is a flag that allows the temporary save the pasword for the current session.
The question is: does someone know if it possible to permanetly memorize the password and not only for that session ? I would like to memorize the password and then being able to modify it in the future.
