About CyberChef
CyberChef is a web app from GCHQ, the UK's signals intelligence agency, released as open source. It offers hundreds of operations, including Base64 and hex encoding, character set conversion, hashing, encryption and decryption, compression, regex extraction, date and time parsing, and file format detection. Instead of picking one tool at a time, you drag operations into a recipe that runs in order, so a messy blob of data can be decoded, decompressed and parsed in one pass, and the recipe can be saved or shared as a link. All processing happens in the browser; nothing is uploaded, and the whole app can be downloaded as a single file to use offline. It is popular with security analysts and CTF players as well as developers. It is free under the Apache 2.0 licence, and the interface is functional rather than polished.
Best for: Security analysts and developers who decode, transform or analyse data in multi-step pipelines.
