CyberChef Server – A Comprehensive Guide To Setting Up And Using A CyberChef API

CyberChef has a useful Node.js API, but sometimes we want to be able to programmatically run CyberChef recipes in languages other than JavaScript.

By running this server, you can use CyberChef operations in any language, as long as you can communicate via HTTP.

Example Use

Assuming you’ve downloaded the repository and are running it locally:

curl -X POST -H "Content-Type:application/json" -d '{"input":"... ---:.-.. --- -. --. --..--:.- -. -..:- .... .- -. -.- ...:..-. --- .-.:.- .-.. .-..:- .... .:..-. .. ... ....", "recipe":{"op":"from morse code", "args": {"wordDelimiter": "Colon"}}}' localhost:3000/bake

response

{
    value: "SO LONG, AND THANKS FOR ALL THE FISH",
    type: "string"
}

Features

  • Compatible with recipes saved from CyberChef. After using CyberChef to experiment and find a suitable recipe, the exported recipe JSON can be used to post to the /bake endpoint. Just copy/paste it in as your recipe property as part of the POST body.

Installing

  • Clone the repository
  • cd into the project and run npm install
  • Run npm run
  • In a browser, navigate to localhost:3000 to see usage documentation.

Docker

A Docker image can be built, then run by doing the following:

  • git clone https://github.com/gchq/CyberChef-server
  • cd CyberChef-server
  • docker build -t cyberchef-server .
  • docker run -it --rm --name=cyberchef-server -p 3000:3000 cyberchef-server
