CyberChef

The web tool for encoding, decoding, hashing and analysing data.

CyberChef is GCHQ's browser-based data workbench. You chain operations such as base64, XOR, AES, gzip, regex and hex into a recipe, with a Magic operation that guesses the encoding. It runs locally in the browser, so data stays on your machine.

Why it's useful

Solves a large share of CTF crypto and forensics puzzles.
