CyberChef
CyberChef is ideal for rapid transformation pipelines: decode, inspect, branch, and iterate without writing throwaway scripts first.
Core use in crypto/reversing
- Unwrap nested encodings (Base64/Hex/URL/gzip/rot/XOR).
- Test candidate keys/IVs quickly for block/stream ciphers.
- Analyze unknown blobs via
Magic before custom code.
- Export reproducible recipes through URL hash or saved JSON.
High-value workflow
- Load input (text, hex dump, file).
- Start with
Magic and inspect suggestions.
- Build explicit recipe chain (avoid blind overfitting).
- Add breakpoints and step through each operation.
- Export URL/recipe JSON for reproducibility and script handoff.
Deep-link format
CyberChef supports URL recipes:
https://gchq.github.io/CyberChef/#recipe=<Ops>&input=<Base64Input>
This is useful for teammate handoff and agent reproducibility.
Local/offline options
- Browser app is client-side by design.
- For isolated environments, run local Docker image and use local browser access.
Automation bridge
When recipe stabilizes and must be automated at scale:
- Move from web recipe to CyberChef Node API (
chef.bake) or to Python equivalents.
- Keep operation order and arguments identical.
Browser interaction note
CyberChef is a web-first tool. If interactive browser steps are required and cannot be executed automatically in the current environment, request user-assisted interaction (e.g., upload input blob, verify candidate recipe output).
