Things You Should Know
There are four parts of CyberChef
Operations: The operations are in the column on the left. It holds all of the processes and actions you can use to get to your goal.
Recipe: You drag the actions from the operations column to the recipe column. This is where the computer is told what processes it will be doing, whether its encoding in base64, decoding a URL, or something else.
Input: The input is where you put your ingredients. Or more specifically, you put a string that you want to translate or convert from one thing to another using your recipe.
Output: The output area is what happens once your input is converted through your recipe. It spits out what you tell it to by following your recipe.
