PDF files password cracker

PDFCrack is a simple tool for recovering passwords from pdf-documents.

It should be able to handle all pdfs that uses the standard security handler but the pdf-parsing routines are a bit of a quick hack so you might stumble across some pdfs where the parser needs to be fixed to handle.

The main PDFCrack features are:

  - Supports the standard security handler (revision 2, 3 and 4) on all known
    PDF-versions.
  - Supports cracking both owner and userpasswords.
  - Both wordlists and bruteforcing the password are supported.
  - Simple permutations (currently only trying first character as Upper Case).
  - Save and load a running job.
  - Simple benchmarking.
  - Optimised search for owner-password when user-password is known.

This program can be used in forensics investigations or similar activities, to legal password crack.
