pdfcrack – PDF files password cracker
pdfcrack -f filename [options]
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.
Perform benchmark and exit.
Use the characters in STRING as charset.
Stop when reaching INTEGER as password length.
Skip trying passwords shorter than INTEGER.
Continue from the state saved in FILENAME.
Work with the ownerpassword.
Uses STRING as userpassword to speed up breaking ownerpassword (implies -o).
Try permutating the passwords (currently only supports switching first character to uppercase).
Work with the userpassword (default).
Print version and exit.
Use FILE as source of passwords to try.
