PDFCrack is a GNU/Linux (other POSIX-compatible systems should work too) tool for recovering passwords and content from PDF-files. It is small, command line driven without external dependencies. The application is Open Source (GPL).
Features:
* Supports the standard security handler (revision 2 and 3) on all known PDF-versions
* Supports cracking both owner and userpasswords
* Both wordlists and bruteforcing the password is supported
* Simple permutations (currently only trying first character as Upper Case)
* Save/Load a running job
* Simple benchmarking
* Optimised search for owner-password when user-password is known
Install pdfcrack in Ubuntu
sudo aptitude install pdfcrack

thanks Nikesh !
Not knowing what to do next
I type in:
pdfcrack file1.pdf
and pdfcrack immediately comes up:
Error: Encryption not detected (is the document password protected?)
Well yes it is, in that it can be read by anyone, but cannot be altered. I just want to add a new page, but no editing program will touch it, and pdfcrack won't do anything.
