gchq/cyberchef — reverse-engineered prompt

Build me a browser based CyberChef style web app that works like a cyber Swiss army knife for data. I want a big input area where I can paste text or drop a file, an output area that updates when the data is processed, a searchable list of operations on the left, and a middle recipe area where I can drag operations in order.

It should support common tasks like Base64, XOR, hashes, checksums, AES, DES, compression and decompression, hex dumps, character encoding changes, IPv6 and certificate parsing, and simple data cleanup. Let users chain multiple steps together, change options for each step, turn automatic processing on or off, and step through a recipe to see what changed.

Please keep everything client side so private input never leaves the browser. Add save and load recipes, shareable URLs that include the recipe and input, file import and export, and a magic detect button that tries to guess useful decoding steps. Make it easy to run locally, including with Docker if possible.
