I published a PDF document ten years ago and now want to add Creative Commons licensing language to the copyright page. But I forgot the password! I gather from the Forum that there is no way to recover the password. However, I wonder if I can take the locked PDF file, create a new document (adding a new page for the licensing information), then lock the whole thing up again. Will this work? Thanks for your help!
To create an unprotected file you would need the password.
