About CyberChef
CyberChef is a browser-based tool for working with data through a set of operations, including encoding, decoding, encryption, compression, and data analysis. Users select operations from a categorised, searchable list and arrange them in a recipe. The input is then processed by the recipe, and the output is shown in a separate pane.
The tool can run recipes automatically when the input or recipe changes, using its auto-bake setting. Recipes can be saved to local storage or shared through a deep link. Auto-bake applies only to the active tab when there are multiple inputs; other inputs must be baked manually.
Key features

- Recipe pane for chaining operations in a chosen order
- Auto-bake that reprocesses input when the recipe or input changes
- Input by typing, pasting, dragging, or loading files or folders

- Operations can be combined into a recipe and reordered by dragging.
- Recipes can be saved locally or shared through a deep link.
