CyberChef
Chain encoding, hashing, compression, and data-analysis operations in the browser.
What it is
CyberChef is a browser-based data tool published by GCHQ. Add operations to a recipe to encode, hash, compress, convert, or parse input, with the result shown in the same workspace.
Why it is selected
One-off data conversions often require looking up a command or writing a small script. CyberChef turns those steps into an adjustable recipe, which makes experimentation and output checks quicker.
Who it suits
Developers and security analysts working with encoded data, hashes, logs, or file fragments.
Useful for
- Converting Base64, hexadecimal, and text encodings
- Chaining operations and checking the data after each step
Usage note
The official documentation says input data and recipes are processed in the browser, but Show on map, DNS over HTTPS, and HTTP request connect to external services. Check the recipe and browser network requests before handling sensitive data.
