About CyberChef

Created by the UK Government Communications Headquarters (GCHQ), CyberChef is a powerhouse utility. Users build "recipes" by dragging and dropping operations—such as converting Hex to Base64, unescaping HTML, decompressing Gzip, parsing JWT tokens, computing AES hashes, and extracting IP addresses. Everything executes 100% locally in your browser.

Best for: Security researchers, backend developers, and DevOps engineers debugging tokens and encodings.
