## Common questions

### Can I use CyberChef programmatically from Node.js?

Yes. Install the npm package with npm install --save cyberchef, then run npm run repl to open a command-line prompt and test CyberChef commands.

### Why would a self-hoster run CyberChef locally?

A self-hosted discussion says it can help keep data away from external privacy policies and avoid exposure, even when the tool relies on client-side rendering.

### What self-hosting concerns should I plan for when running CyberChef in Docker?

The guide covers secure access, stateless hosting, Docker, ports, persistent data, TLS, security, and backups, including failures that can block production use.

### How can I use CyberChef on an unknown string in a CTF-style task?

You can put the string into CyberChef and try different algorithms in the recipe until it looks deciphered, although the source notes the string may not be encoded at all.
