About CyberChef
CyberChef is a web app for working with data, often described as a cyber Swiss army knife. It runs in the browser and handles encoding, encryption, compression, hashing and analysis tasks.
What it does
You choose operations from a categorised list and chain them into a recipe. The input is transformed step by step, and the output updates as you change settings. Most of the work happens locally in the browser, so pasted data is processed on your own device.
Key features
- More than 500 operations for data conversion
- Recipes that re-run on each change with Auto Bake
- Encoding, encryption and hashing tools
- Compression and decompression
- Entropy and hexdump views for data inspection
- Can be downloaded as a standalone file
Who it's for
Security analysts, reverse engineers, developers and students who often decode or transform data. It is useful for quick checks that would otherwise need several small scripts.
Pricing and good to know
CyberChef is open source under the Apache-2.0 license and is free to use. It can be opened online or downloaded as a standalone file to run offline. The operation list is long, so searching by name is faster than browsing categories. Check results carefully when you work with sensitive data.
