We would like to know if a user opens a protected PDF (with 128/256 bits encryption) in Acrobat Reader 9.0,
can the user save a copy of the protected PDF and the new PDF is no longer password protected.
That means I would like to check if the reader 9.0 can allow user to remove the password (Of course, permission
should be granted when creating the protected PDF in Acrobat 9.0) from the protected PDF file.
Thanks for your attention in advance,
