Installing

CyberChef uses the Grunt build system, so it's very easy to install. You'll need to carry out the following steps to get going:

  1. Install Git
  2. Install Node.js and its package manager, npm
  3. Install Grunt: npm install -g grunt-cli
  4. git clone https://github.com/gchq/CyberChef.git
  5. cd CyberChef
  6. npm install

npm will then install all the dependencies needed by Grunt.

Compiling

Grunt has been configured with several tasks to aid in the development process:

grunt dev

Use this when developing new functionality. It will launch a persistent task which will automatically build an uncompressed, development version of CyberChef located in build/dev. Whenever a source file is modified, the development version will be rebuilt.

grunt prod

When you are ready to create a production build, run this command. It will lint, test, concatenate, and compress all the source files and create a production-ready build in build/prod. It will also create the inline version of CyberChef at the same location, called cyberchef.htm.

grunt node

This will package up CyberChef as a NodeJS library, creating the file build/node/CyberChef.js. It can then be loaded and used like so:

> var chef = require("./CyberChef.js")
undefined
> chef.bake("test", [{"op":"To Hex","args":["Space"]}])
{ result: '74 65 73 74',
  type: 'string',
  progress: 1,
  options: {},
  duration: 2,
  error: false }
grunt test

This will run all the pre-configured tests and output the results to stdout.

grunt docs

Builds the codebase documentation and places it in the docs directory.
