CyberChef
gchq.github.io/CyberChef
The local-first digital Swiss Army knife for analyzing, converting, and transforming data formats through simple drag-and-drop recipes.
CyberChef features an intuitive visual canvas for assembling computational recipes. Users drag and drop operations to perform base64 encoding, hex conversion, timestamp parsing, cryptographic operations, and text extraction — all running entirely in the browser without sending data anywhere.
Why it is useful
It replaces dozens of sketchy ad-ridden web formatters with an elegant, client-side toolkit that keeps your data in your browser. Originally built by security analysts at GCHQ, its visual recipe builder compresses hours of manual data wrangling into a few drag-and-drop steps.
