# Data Tools

> Offline encryption, encoding, hashing, and data analysis via CyberChef.

Data Tools brings [CyberChef](https://gchq.github.io/CyberChef/) to your N.O.M.A.D. server, running fully offline. CyberChef is a powerful browser-based tool for encryption, encoding, hashing, and a wide range of data transformations. Because it runs locally on your server, no data you process is ever sent to an external service.

## How to access

Go to **Settings → Apps** and open Data Tools from the installed apps list.

## What you can do

<CardGroup cols={2}>
  <Card title="Encrypt and decrypt" icon="lock">
    Apply symmetric encryption algorithms (AES, DES, Blowfish, and more) to protect sensitive data or recover plaintext from ciphertext.
  </Card>

  <Card title="Encode and decode" icon="arrow-right-arrow-left">
    Convert data between Base64, hexadecimal, URL encoding, HTML entities, and many other formats.
  </Card>

  <Card title="Hash files and text" icon="hashtag">
    Generate MD5, SHA-1, SHA-256, SHA-512, and other checksums to verify file integrity or store passwords securely.
  </Card>

  <Card title="Analyze data" icon="chart-bar">
    Inspect binary data, detect file types, extract strings, and perform frequency analysis on encoded content.
  </Card>

## 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.

<Note>
  N.O.M.A.D. has zero built-in telemetry. The Data Tools feature operates entirely within your local network.
</Note>

## 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](https://gchq.github.io/CyberChef/). 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.
