Dear Readers,
In this blog we are going to learn, about a Platform known as “CyberChef” which is a free and open-source, web based security analysis tool developed by GCHQ (UK’s Government Communications Headquarters) which is a government intelligence agency.
What is CyberChef?
CyberChef is a web-application developed by GCHQ that’s been called the “Cyber Swiss Army Knife”. From the CyberChef Github page:
“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.”
This tool can be downloaded from Github and run on your local machine, or it can be run inside the browser at this link: https://gchq.github.io/CyberChef/
What is CyberChef used for?
CyberChef can be used to: Encode, Decode, Format data, Parse data, Encrypt, Decrypt, Compress data, Extract data, perform arithmetic functions against data, defang data, and many other functions.
How do I get started?
Go to: https://gchq.github.io/CyberChef/
From there, you’ll see 4 sections:
- Operations on the left side – These are how the manipulations you want to perform on the data.
- Recipe in the middle – These are the instructions telling Cyberchef what to do with the data.
- Input section on the top right side – This is the data you provide that you’re manipulating.
- Output section on the bottom right side – This is the result of the Input + Recipe functions
