These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.
+CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR and Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.
 
 The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.

Consisting of 15 rotors: 5 cipher rotors and 10 rotors (5 control rotors and 5 index rotors) controlling the stepping of the cipher rotors, the rotor stepping for SIGABA is much more complex than other rotor machines of its time, such as Enigma. All example rotor wirings are random example sets.<br><br>To configure rotor wirings, for the cipher and control rotors enter a string of letters which map from A to Z, and for the index rotors enter a sequence of numbers which map from 0 to 9.
