The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis
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 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.
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.
CyberChef is still under active development. As a result, it shouldn't be considered a finished product. There is still testing and bug fixing to do, new features to be added and additional documentation to write. Please contribute!
Cryptographic operations in CyberChef should not be relied upon to provide security in any situation. No guarantee is offered for their correctness.
A live demo can be found here - have fun!
There are four main areas in CyberChef:
You can use as many operations as you like in simple or complex ways. Some examples are as follows:
By manipulation of CyberChef's URL hash, you can change the initial settings with which the page opens.
The format is
Supported arguments are

CyberChef is built to fully support Node.js
v10 and partially supports
v12. Named imports using a deep import specifier does not work in
v12. For more information, see the Node API page in the project wiki pages
An installation walkthrough, how-to guides for adding new operations and themes, descriptions of the repository structure, available data types and coding conventions can all be found in the project wiki pages.
