Author Bug#380328: ITP: pdfcrack -- PDF files password cracker
Nacho Barrientos Arias

2006-07-29, 7:33 am

Package: wnpp
Severity: wishlist
Owner: Nacho Barrientos Arias <chipi@criptonita.com>

* Package name : pdfcrack
Version : 0.7
Upstream Author : Henning Noren <confusion42@users.sourceforge.net>
* URL : http://sourceforge.net/projects/pdfcrack
* License : GPL
Programming Lang: C
Description : 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.

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

This software uses xpdf/poppler stuff (categorized as free).

Cracking pdfs is not something an admin would usually do.

What could be the best section for this package? 'admin' like
"john" (pdfcrack has got a similar behaviour) or 'utils'?

"john" is in admin because it's intended to be run by the administrator
to check if any of the users have a weak password. "pdfcrack" is to be
used by a user who has forgotten the password of a PDF, thus making it
more suitable for 'utils' or 'text'.

Hi there,

Does this use xpdf or poppler?
poppler is a fork of xpdf which allows dynamic linking, so is much
preferred from a security-support POV.
