PDF Security
« on: September 12, 2012, 10:04:41 am »
For the first time I am using the security options when generating a PDF for web. However, though I set the options that only the owner (me) can change or copy the content, I can copy anything from the PDF without being prompted for a password.

I've submitted a password only for the owner, not for the user, because as soon as I submit a pw for the user, I will be prompted for a pw as soon as I want to open the file.

It could be that my pw is remembered on my system or stored in the pw key chain (I'm on Mac OS X 10.6.8 running Scribus 1.4.1 with GhostScript).

Maybe someone can test part of the file for me and confirm that the content is password protected?

The PDF is located here:

If the pw protection shouldn't work - how can I set up the PDF export so that nobody can copy the content? Any ideas or hints are welcome!

I've just uploaded a screenshot of my security settings:

hi jens

your test file is protected. in adobe reader you can't copy anything – but some pdf readers override password protection (it's not really save!)

Hi Utnik,

thanks for testing my file. So my system must have stored my 'standard' pw in the keychain...

I know that there are even progs and apps to crack PDF passwords, but I just want to avoid that a standard user can just grab my images 'on the fly'.

The Internet turned into a battlefield, carrying the title 'This is WAR'.

Again, thanks a lot, I really enjoy to use Scribus (trashed my InDesign some time ago) and this forum is great!
