Origapy is a Python interface to Origami, a PDF parser written in Ruby. It provides access to pdfclean.rb, in order to sanitize PDF files by disabling all active content (javascript, launch actions, embedded files, etc). Because Origami is a full PDF parser, it is much more effective than PDFiD (when sanitizing/disarming PDF files), but also quite slower.

PDF files may be used to trigger malicious content, as described here. PDFiD is a Python tool to analyze and sanitize PDF files, written by Didier Stevens. Here is PDFiD_PL, a version that I have slightly modified so that it can be imported as a module in Python applications (originally for ExeFilter).

pyxmldsig is a Python module to create and verify XML Digital Signatures (XML-DSig). This is a simple interface to the PyXMLSec library, aiming to provide a more pythonic API suitable for Python applications.

With Python 2.6+, that's quite simple:

print "{0:b}".format(i)

This is a Python course I have written to quickly teach Python to my colleagues and students, made of slides and samples for hands-on exercises.

This short article shows how ExeFilter can be used to disable JavaScript in PDF files, which is effective against many Adobe Reader exploits discovered in 2009, including the recent zero-day CVE-2009-4324.

I had to search quite a bit to find the easiest way to install Ruby and ruby-gtk2 on Windows. Here's what I found so far:
