pdfcrack 0.11-1 (armhf binary) in ubuntu trusty

 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.
 .
 pdfcrack allows configure the size of the searched password, use an
 external wordlist file and save cracking sessions to restore it later.
