NAME
pdfcrack – PDF files password cracker

SYNOPSIS
pdfcrack -f filename [options]

DESCRIPTION
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.

OPTIONS
-b, –bench
Perform benchmark and exit.

-c, –charset=STRING
Use the characters in STRING as charset.

-m, –maxpw=INTEGER
Stop when reaching INTEGER as password length.

-n, –minpw=INTEGER
Skip trying passwords shorter than INTEGER.

-l, –loadState=FILE
Continue from the state saved in FILENAME.

-o, –owner
Work with the ownerpassword.

-p, –password=STRING
Uses STRING as userpassword to speed up breaking ownerpassword (implies -o).

-q, –quiet
Run quietly.

-s, –permutate
Try permutating the passwords (currently only supports switching first character to uppercase).

-u, –user
Work with the userpassword (default).

-v, –version
Print version and exit.

-w, –wordlist=FILE
Use FILE as source of passwords to try.
