About this copy
CyberChef is built by GCHQ and its contributors. I host a copy here and add recipes I find useful. This copy is version 11.5.0.
Private: runs in your browser
This tool runs entirely on your device. What you enter isn't sent to this site or to any other service, and nothing is kept after you leave the page.
One exception you control: CyberChef's network operations, such as HTTP request, contact whatever address you give them. Shared recipe links can contain your input, so check a link before you send it. Saved recipes stay in this browser's local storage, and opening a local file reads it in the browser without uploading it.
