![]() ![]() This can be run locally or hosted on a web server with no configuration required.īe aware that the standalone version will never update itself, meaning it will not receive bug fixes or new features until you re-download newer versions manually. If you would like to download your own standalone copy of CyberChef to run in a segregated network or where there is limited or no Internet connectivity, you can get a ZIP file containing the whole web app below. You can confirm what network requests are made using your browser's developer console (F12) and viewing the Network tab. There are three operations that make calls to external services, those being the 'Show on map' operation which downloads map tiles from, the 'DNS over HTTPS' operation which resolves DNS requests using either Google or Cloudflare services, and the 'HTTP request' operation that calls out to the configured URL you enter. There are around 200 useful operations in CyberChef for anyone working on anything vaguely Internet-related, whether you just want to convert a timestamp to a different format, decompress gzipped data, create a SHA3 hash, or parse an X.509 certificate to find out who issued it.ĬyberChef runs entirely within your browser with no server-side component, meaning that your Input data and Recipe configuration are not sent anywhere, whether you use the live, official version of CyberChef or a downloaded, standalone version (assuming it is unmodified). It is hoped that by releasing CyberChef through GitHub, contributions can be added which can be rolled out into future versions of the tool. It should also appeal to the academic world and any individuals or companies involved in the analysis of digital data, be that software developers, analysts, mathematicians or casual puzzle solvers. It is expected that CyberChef will be useful for cybersecurity and antivirus companies. Simple functions can be combined to build up a "recipe", potentially resulting in complex analysis, which can be shared with other users and used with their input.įor those comfortable writing code, CyberChef is a quick and efficient way to prototype solutions to a problem which can then be scripted once proven to work. Complex techniques are now as trivial as drag-and-drop. The interface is designed with simplicity at its heart. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.ĭigital data comes in all shapes, sizes and formats in the modern world – CyberChef helps to make sense of this data all on one easy-to-use platform. ![]() The command then processes the data and outputs the result to standard output, which can be redirected to a file or piped to another command for further processing.A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. To use the “base64” command, you provide the appropriate options and arguments to specify the desired encoding or decoding operation and the input source. It is also frequently employed in cryptographic applications or when working with data that needs to be represented in a portable and human-readable form. ![]() For example, it is commonly used for securely transmitting binary data over text-based protocols or storing binary data in formats that only support text. The “base64” command is useful in various scenarios. This decoding process reverses the encoding and retrieves the original binary data from the Base64-encoded string. Conversely, when decoding with Base64, the “base64” command takes a Base64-encoded ASCII string as input and converts it back into its original binary representation.
