## Databunker intro

### 💣 The Big Problem with Traditional Database Encryption
Traditional database encryption solutions often provide a false sense of security. While they may encrypt data at rest, they leave critical vulnerabilities:

* **Encryption alone isn’t enough:** Most vendors offer only disk-block encryption, ignoring API-level encryption
* **Vulnerable GraphQL Queries:** Unfiltered queries can expose unencrypted data to attackers
* **SQL Injection Risks:** Attackers can retrieve plaintext data through SQL injections

Databunker addresses these gaps with a secure, developer-focused solution for personal data tokenization and storage.

### 🛠️  DataBunker Features

- **Tokenization Engine**: Generates UUID tokens for safe data referencing in applications
- **Encrypted Storage**: Secures sensitive records with advanced encryption layer
- **Injection Protection**: Blocks SQL and GraphQL injection attacks by design
- **Secure Indexing**: Uses hash-based indexing for search queries
- **No Plaintext Storage**: Ensures all data is encrypted at rest
- **Restricted Bulk Retrieval**: Disabled by default to prevent data leaks
- **API-Based Access**: Integrates with your backend via a NoSQL-like API
- **Fast Integration**: Set up secure data protection in under 10 minutes

### ⚡ Why Databunker?

Databunker provides a robust, open-source vault that eliminates the false sense of security from traditional encryption methods, offering developers a practical way to protect sensitive data.

### 🚀 Deployment & Usage
- **Self-Hosted**: Run on your cloud or on-premises infrastructure
- **Open-Source**: Licensed under MIT for free commercial use
- **GDPR Compliant**: Meets modern privacy regulation requirements
- **High Performance**: Go-powered API ensures fast tokenization and data access

### 🔐 How It Works
1. Store sensitive data in Databunker via API calls
2. Receive UUID tokens to reference data securely in your application
3. Query data using secure, hash-based indexing
4. Benefit from built-in protections against injections and bulk data leaks

## 🚀 Quick Start (5 minutes)

```bash
# Pull and run Databunker container
docker pull securitybunker/databunker
docker run -p 3000:3000 -d --rm --name dbunker securitybunker/databunker demo

# Create user records
curl -s http://localhost:3000/v1/user -X POST \
  -H "X-Bunker-Token: DEMO" \
  -H "Content-Type: application/json" \
  -d '{"first":"John","last":"Doe","login":"john","email":"user@gmail.com"}'

# Get user by login, email, phone, or token
curl -s -H "X-Bunker-Token: DEMO" -X GET http://localhost:3000/v1/user/login/john

# Admin UI: http://localhost:3000
```
