In 2007 using Adobe Acrobat I made secure files of my PDF book so that when I gave people copies they could not edit the file or print it.
I cant seem to find my original file and only the secure one. Now I want to print off a section of the book and I cant. I have in 7 years forgotten the password.
Can any one help me in finding out how to remove the security on my own file when I have forgotten the password?
Any help appreciated
You will need to look to a third party for tools that can help you. Adobe doesn't provide those types of tools.
I have the same problem and I don´t believe that Adobe doesn't have a tools, Sabian Zildjian do you know tools for restore the password?
Adobe do not have such tools because they could be used by anyone, not just the owner. What would be the point of setting security then selling tools to remove it?
Adobe do not permit discussion of specific password removal techniques here.
