What is CyberChef?

CyberChef is a web-based application that allows users to encode, decode, encrypt, decrypt, and analyze data through a simple drag-and-drop interface. It supports numerous operations, from simple tasks like converting text to Base64 or hexadecimal, to more complex operations such as AES encryption and decryption.

Key Features of CyberChef:

  • User-Friendly Interface: Its intuitive, drag-and-drop interface makes it accessible even for those without extensive programming knowledge.
  • Wide Range of Operations: CyberChef supports a vast library of operations, including encoding, encryption, compression, and data analysis.
  • Customizable Recipes: Users can create and save custom operation chains, called "recipes," to automate repetitive tasks.
  • Web-Based Application: Being web-based, CyberChef can be run in any modern web browser without requiring installation.

How to Use CyberChef

Using CyberChef involves loading data, selecting operations, and executing a "recipe." Here’s a step-by-step guide: — Maria Gianniti: A Look Into Her Private Life

  1. Load Data: Input the data you want to manipulate into the input box. This could be text, hexadecimal code, or any other data format.
  2. Select Operations: Choose the operations you want to perform from the left-hand menu. Drag and drop these operations into the "recipe" area.
  3. Configure Operations: Adjust the settings for each operation as needed. For example, when using AES encryption, you’ll need to provide a key and IV (Initialization Vector).
  4. Execute Recipe: CyberChef automatically executes the recipe as you build it, displaying the results in the output box.

Example: Decoding a Base64 String

Let's say you have a Base64 encoded string: SGVsbG8gV29ybGQh

  1. Load this string into the input box.
  2. Drag the "From Base64" operation from the menu to the recipe area.
  3. CyberChef instantly decodes the string, and the output box will display: Hello World!
