CyberChef is a simple, intuitive web app for carrying out "cyber" operations within a web browser.

These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES, and Blowfish, creating binary and hex dumps, compression and decompression of data calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

The tool enables technical and non-technical analysts to manipulate data in complex ways without dealing with complex tools or algorithms. It was conceived, designed, built, and incrementally improved by an analyst in their 10% innovation time over several years.

An online demo is available here.
