Yeh that's true.. But I came to a weird pdf document lately... This document
is a secured PDF but it has got no File ID entry on the trailer section...
Tried using Itext to handle the file, but it fails when computing the user
key... One thing that makes this case interesting is that adobe reader can
open the file with no problem... Maybe there is another algorithm that adobe
uses to handle this kind of file?? Any insights on this matter??
