How to access
Go to Settings → Apps and open Data Tools from the installed apps list.What you can do
Encrypt and decrypt
Apply symmetric encryption algorithms (AES, DES, Blowfish, and more) to protect sensitive data or recover plaintext from ciphertext.
Encode and decode
Convert data between Base64, hexadecimal, URL encoding, HTML entities, and many other formats.
Hash files and text
Generate MD5, SHA-1, SHA-256, SHA-512, and other checksums to verify file integrity or store passwords securely.
Analyze data
Inspect binary data, detect file types, extract strings, and perform frequency analysis on encoded content.
Privacy
All data processing in CyberChef happens locally in your browser — nothing leaves your device. This makes it suitable for working with sensitive documents, credentials, or any data you would not want to send to a third-party service.N.O.M.A.D. has zero built-in telemetry. The Data Tools feature operates entirely within your local network.
Use cases
- Encoding data for transmission — Convert binary files or structured data to Base64 for safe inclusion in text-based protocols or messages.
- Verifying file integrity — Hash a file before and after transfer to confirm it arrived unchanged.
- Encrypting sensitive documents — Apply AES or other ciphers to protect files before storing or sharing them.
- Decoding unknown data — Identify and reverse encoding schemes applied to captured or received data.
- Offline security work — Perform cryptographic operations without exposing keys or plaintext to the internet.
About CyberChef
CyberChef is an open-source project developed by GCHQ. It provides hundreds of individual operations that can be chained together into “recipes” for multi-step transformations. N.O.M.A.D. includes a self-hosted copy so the full tool is available offline.Related
