Chepy is a python library with a handy cli that is aimed to mirror some of the capabilities of CyberChef. A reasonable amount of effort was put behind Chepy to make it compatible to the various functionalities that CyberChef offers, all in a pure Pythonic manner. There are some key advantages and disadvantages that Chepy has over Cyberchef. The Cyberchef concept of stacking different modules is kept alive in Chepy.
There is still a long way to go for Chepy as it does not offer every single ability of Cyberchef.
Refer to the docs for full usage information
For all usage and examples, see the docs.
Chepy has a stacking mechanism similar to Cyberchef. For example, this in Cyberchef:
This is equivalent to
from chepy import Chepy file_path = "/tmp/demo/encoding" print( Chepy(file_path) .load_file() .reverse() .rot_13() .base64_decode() .base32_decode() .hexdump_to_str() .o )
Chepy vs Cyberchef
- Chepy is pure python with a supporting and accessible python api
- Chepy has a CLI
- Chepy CLI has full autocompletion.
- Supports pe, elf, and other various file format specific parsing.
- Extendable via plugins
- Infinitely scalable as it can leverage the full Python library.
- Chepy can interface with the full Cyberchef web app to a certain degree. It is easy to move from Chepy to Cyberchef if need be.
- The Chepy python library is significantly faster than the Cyberchef Node library.
- Works with HTTP/S requests without CORS issues.
- Chepy is not a web app (at least for now).
- Chepy does not offer every single thing that Cyberchef does
- Chepy does not have the
magicmethod (at the moment)
Chepy can be installed in a few ways.
pip3 install chepy # optionally with extra requirements pip3 install chepy[extras]
git clone --recursive https://github.com/securisec/chepy.git cd chepy pip3 install -e . # I use -e here so that if I update later with git pull, I dont have it install it again (unless dependencies have changed)
docker run --rm -ti -v $PWD:/data securisec/chepy "some string" [somefile, "another string"]
One can build Chepy to be a standalone binary also. This includes packaging all the dependencies together.
git clone https://github.com/securisec/chepy.git cd chepy pip install . pip install pyinstaller pyinstaller cli.py --name chepy --onefile
The binary will be in the dist/ folder.
