How to find PDF Salt

["Atul Porwal" <atul_porwal () infosys com>]

Hi All,

I am trying to break one .PDF file, This file is protected with FOPN_fLock /V 1 Plug-in.
I got one source code to exploit this particular vulnerability from 
http://www-2.cs.cmu.edu/~dst/Adobe/Gallery/fileSaveAs.c
But this souce code needs salt used for encrypting file. 
Can Anybody throw some light on this!!!


TIA
