I'd like to be able to password protect or encrypt my PDF file so that no one can possibly modify my fields or calculations, scripts and fields using Designer. That is, after I add fields to a PDF form using Designer, I would like no one to be able to load this form in their designer and modify or copy an of the work I've done.
Although, I'd like for anyone to be able to still fill out the form using adobe reader without having to enter a password.
Is this possible in acrobat 7 or 8?
thanks,
Scott
