pwnypack 0.7.2

Official Certified Edible Dinosaurs CTF toolkit.

pwnypack

The official Certified Edible Dinosaurs CTF toolkit. pwnypack attempts to provide a toolset which can be used to more easily develop CTF solutions.

Motivation

After seeing the excellent pwntools by Gallopsled, I got interested in building my own CTF toolkit. pwntools is much more complete so you should probably use that. pwnypack was created mostly out of curiosity.

Installation

To install the latest released version of pwnypack, use:

$ pip install pwnypack

If you want to use the interactive shell I highly recommend installing either bpython or ipython as those packages can make your time in the shell a lot more enjoyable.

Usage

To import all of pwnypack into your global namespace, use:

>>> from pwny import *

Or, if you’re using python 2.7+ or python 3.3+, try the customized bpython or IPython shell:

$ pwny shell

If you have bpython and/or IPython installed you can use --bpython, --ipython or --python to select which interactive kernel to use.

I promise that effort will be put into not exposing unnecessary stuff and thus overly polluting your global namespace.

For an example, check out the Big Prison Fence example in the wiki.

Documentation

pwnypack’s API documentation is hosted on readthedocs.

For information on the commandline apps use the built in help function:

$ pwny --help
$ pwny shell --help
