Security Configuration

Protect your Open Notebook deployment with password authentication and production hardening.

---

API Key Encryption

Open Notebook encrypts API keys stored in the database using Fernet symmetric encryption (AES-128-CBC with HMAC-SHA256).

Configuration Methods

Method	Documentation
Settings UI	API Configuration Guide
Environment Variables	This page (below)

Setup

Set the encryption key to any secret string:

# .env or docker.env
OPEN_NOTEBOOK_ENCRYPTION_KEY=my-secret-passphrase

Any string works — it will be securely derived via SHA-256 internally. Use a strong passphrase for production deployments.

Default Credentials

Setting	Default	Security Level
Password	open-notebook-change-me	Development only
Encryption Key	None (must be configured)	Required for API key storage

The encryption key has no default. You must set OPEN_NOTEBOOK_ENCRYPTION_KEY before using the API key configuration feature. Without it, encrypting/decrypting API keys will fail.

Docker Secrets Support

Both settings support Docker secrets via _FILE suffix:

environment:
  - OPEN_NOTEBOOK_PASSWORD_FILE=/run/secrets/app_password
  - OPEN_NOTEBOOK_ENCRYPTION_KEY_FILE=/run/secrets/encryption_key

Security Notes

Scenario	Behavior
Key configured	API keys encrypted with your key
No key configured	Encryption/decryption will fail (key is required)
Key changed	Old encrypted keys become unreadable
Legacy data	Unencrypted keys still work (graceful fallback)

Key Management

• Keep secret: Never commit the encryption key to version control
• Backup securely: Store the key separately from database backups
• No rotation yet: Changing the key requires re-saving all API keys
• Per-deployment: Each instance should have its own encryption key

---

When to Use Password Protection

Use it for:

• Public cloud deployments (PikaPods, Railway, DigitalOcean)
• Shared network environments
• Any deployment accessible beyond localhost

You can skip it for:

• Local development on your machine
• Private, isolated networks
• Single-user local setups

---

Quick Setup

Docker Deployment

# docker-compose.yml
services:
  open_notebook:
    image: lfnovo/open_notebook:v1-latest-single
    pull_policy: always
    environment:
      - OPEN_NOTEBOOK_ENCRYPTION_KEY=your-secret-encryption-key
      - OPEN_NOTEBOOK_PASSWORD=your_secure_password
    # ... rest of config

Or using environment file:

# docker.env
OPEN_NOTEBOOK_ENCRYPTION_KEY=your-secret-encryption-key
OPEN_NOTEBOOK_PASSWORD=your_secure_password

Important: The encryption key is required for credential storage. Without it, you cannot save AI provider credentials via the Settings UI. If you change or lose the encryption key, all stored credentials become unreadable.

Development Setup

# .env
OPEN_NOTEBOOK_PASSWORD=your_secure_password

---

Password Requirements

Good Passwords

# Strong: 20+ characters, mixed case, numbers, symbols
OPEN_NOTEBOOK_PASSWORD=MySecure2024!Research#Tool
OPEN_NOTEBOOK_PASSWORD=Notebook$Dev$2024$Strong!

# Generated (recommended)
OPEN_NOTEBOOK_PASSWORD=$(openssl rand -base64 24)

Bad Passwords

# DON'T use these
OPEN_NOTEBOOK_PASSWORD=password123
OPEN_NOTEBOOK_PASSWORD=opennotebook
OPEN_NOTEBOOK_PASSWORD=admin

---

How It Works

Frontend Protection

1. Login form appears on first visit
2. Password stored in browser session
3. Session persists until browser closes
4. Clear browser data to log out

API Protection

All API endpoints require authentication:

# Authenticated request
curl -H "Authorization: Bearer your_password" \
  http://localhost:5055/api/notebooks

# Unauthenticated (will fail)
curl http://localhost:5055/api/notebooks
# Returns: {"detail": "Missing authorization header"}

Unprotected Endpoints

These work without authentication:

• /health - System health check
• /docs - API documentation
• /openapi.json - OpenAPI spec

---

API Authentication Examples

curl

# List notebooks
curl -H "Authorization: Bearer your_password" \
  http://localhost:5055/api/notebooks

# Create notebook
curl -X POST \
  -H "Authorization: Bearer your_password" \
  -H "Content-Type: application/json" \
  -d '{"name": "My Notebook", "description": "Research notes"}' \
  http://localhost:5055/api/notebooks

# Upload file
curl -X POST \
  -H "Authorization: Bearer your_password" \
  -F "file=@document.pdf" \
  http://localhost:5055/api/sources/upload

Python

import requests

class OpenNotebookClient:
    def __init__(self, base_url: str, password: str):
        self.base_url = base_url
        self.headers = {"Authorization": f"Bearer {password}"}

    def get_notebooks(self):
        response = requests.get(
            f"{self.base_url}/api/notebooks",
            headers=self.headers
        )
        return response.json()

    def create_notebook(self, name: str, description: str = None):
        response = requests.post(
            f"{self.base_url}/api/notebooks",
            headers=self.headers,
            json={"name": name, "description": description}
        )
        return response.json()

# Usage
client = OpenNotebookClient("http://localhost:5055", "your_password")
notebooks = client.get_notebooks()

JavaScript/TypeScript

const API_URL = 'http://localhost:5055';
const PASSWORD = 'your_password';

async function getNotebooks() {
  const response = await fetch(`${API_URL}/api/notebooks`, {
    headers: {
      'Authorization': `Bearer ${PASSWORD}`
    }
  });
  return response.json();
}

Production Hardening

Docker Security

services:
  open_notebook:
    image: lfnovo/open_notebook:v1-latest-single
    pull_policy: always
    ports:
      - "127.0.0.1:8502:8502"  # Bind to localhost only
    environment:
      - OPEN_NOTEBOOK_PASSWORD=your_secure_password
    security_opt:
      - no-new-privileges:true
    deploy:
      resources:
        limits:
          memory: 2G
          cpus: "1.0"
    restart: always

Firewall Configuration

# UFW (Ubuntu)
sudo ufw allow ssh
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw deny 8502/tcp   # Block direct access
sudo ufw deny 5055/tcp   # Block direct API access
sudo ufw enable

# iptables
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
iptables -A INPUT -p tcp --dport 8502 -j DROP
iptables -A INPUT -p tcp --dport 5055 -j DROP

Security Limitations

Open Notebook's password protection provides basic access control, not enterprise-grade security:

Feature	Status
Password transmission	Plain text (use HTTPS!)
Password storage	In memory
User management	Single password for all
Session timeout	None (until browser close)
Rate limiting	None
Audit logging	None

Risk Mitigation

1. Always use HTTPS - Encrypt traffic with TLS
2. Strong passwords - 20+ characters, complex
3. Network security - Firewall, VPN for sensitive deployments
4. Regular updates - Keep containers and dependencies updated
5. Monitoring - Check logs for suspicious activity
6. Backups - Regular backups of data

---

Enterprise Considerations

For deployments requiring advanced security:

Need	Solution
SSO/OAuth	Implement OAuth2/SAML proxy
Role-based access	Custom middleware
Audit logging	Log aggregation service
Rate limiting	API gateway or nginx
Data encryption	Encrypt volumes at rest
Network segmentation	Docker networks, VPC

---

Troubleshooting

Password Not Working

# Check env var is set
docker exec open-notebook env | grep OPEN_NOTEBOOK_PASSWORD

# Check logs
docker logs open-notebook | grep -i auth

# Test API directly
curl -H "Authorization: Bearer your_password" \
  http://localhost:5055/health

401 Unauthorized Errors

# Check header format
curl -v -H "Authorization: Bearer your_password" \
  http://localhost:5055/api/notebooks

# Verify password matches
echo "Password length: $(echo -n $OPEN_NOTEBOOK_PASSWORD | wc -c)"

Cannot Access After Setting Password

1. Clear browser cache and cookies
2. Try incognito/private mode
3. Check browser console for errors
4. Verify password is correct in environment

Security Testing

# Without password (should fail)
curl http://localhost:5055/api/notebooks
# Expected: {"detail": "Missing authorization header"}

# With correct password (should succeed)
curl -H "Authorization: Bearer your_password" \
  http://localhost:5055/api/notebooks

# Health check (should work without password)
curl http://localhost:5055/health

Reporting Security Issues

If you discover security vulnerabilities:

1. Do NOT open public issues
2. Contact maintainers directly
3. Provide detailed information
4. Allow time for fixes before disclosure
