CyberChef is a browser-based web application for performing a wide range of 'cyber' operations such as encryption, encoding, compression, hashing, and data parsing. It lets users chain operations into recipes to manipulate and analyze data without writing code.
Use cases
- decode a base64 string
- encrypt and decrypt data with AES
- calculate hashes and checksums of a file
- parse an X.509 certificate
- convert data to hexdump or binary
- decompress gzip data in the browser
- analyze suspicious encoded payloads
- change character encodings of text
When to choose
- you need quick one-off encoding, encryption, or data transformation without installing tools
- you want a visual, recipe-based way to chain data operations
- you need an offline-capable tool for sensitive data analysis
- both technical and non-technical analysts must manipulate data
When to avoid
- you need programmatic automation at scale in a backend pipeline
- you require very large dataset processing beyond browser memory limits
- you need a dedicated, audited cryptographic implementation for production security
