CyberChef is a browser‑based “Swiss‑army‑knife” for data manipulation that lets you instantly encode, decode, encrypt, compress, hash, parse, and transform text files or binary data using dozens of pre‑built operations. It’s aimed at both technical analysts (e.g., threat hunters, malware researchers) and non‑technical users who need a simple, drag‑and‑drop interface to explore and reformat data without installing complex tools.
