CyberChef
DevelopmentDescription
CyberChef is a free, browser-based utility created by GCHQ (the UK’s Government Communications Headquarters) that serves as a “cyber Swiss-army knife” for data manipulation and analysis. It offers a rich library of operations—such as Base64/hex encoding, encryption (AES, RSA), hashing (MD5, SHA), compression, regex parsing, EXIF extraction, and more - chainable via an intuitive drag-and-drop “recipe” interface. Recipes can be saved, shared, and reused, and all processing occurs locally in your browser with no data sent to remote servers.
