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, 3 and 4) 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

 sudo aptitude install pdfcrack
