CyberChef Installation script

Bash script automating the installation of the latest version of GCHQ's CyberChef on Debian 10 or 11

The final build of CyberChef will be located in

• /var/www/CyberChef

Design principles:

• Create a production build of CyberChef on a (disposable) system with Vagrant. This system has the hostname charpentier.
• Copy the production build to the virtual host server in the ./CyberChef directory.
• Create another Virtual Server using NGINX as the webserver for the build created in the previous step. This has the hostname cyberchef.
• Alternatively copy the build to another Web Server and install NGINX there.

Note: CyberChef now supports Node 16. For a long time Node 10 was a requirement which became an issue.

The simplified installation-flow is depicted below.

You can either just create the build and copy it manually to another system. By using vagrant up charpentier

or you can let it create the webserver automatically, using vagrant up charpentier cyberchef

If you need to start over again, use vagrant destroy -f charpentier cyberchef; vagrant up charpentier cyberchef

CyberChef - The Cyber Swiss Army Knife

From "about" in the web app:

CyberChef is a simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.
