# Secure Database Implementation (Phases 1.2 & 1.3)
|
|
|
|
This implementation adds database encryption at rest and secure session management with token revocation to the Shopify AI App Builder.
|
|
|
|
## Features
|
|
|
|
### Phase 1.2: Database with Encryption at Rest
|
|
- ✅ SQLCipher-encrypted SQLite database with better-sqlite3
|
|
- ✅ Field-level AES-256-GCM encryption for sensitive data
|
|
- ✅ PBKDF2 key derivation (100,000 iterations)
|
|
- ✅ WAL mode for better concurrency
|
|
- ✅ Comprehensive audit logging
|
|
- ✅ Backward compatibility with JSON files
|
|
- ✅ Zero-downtime migration support
|
|
|
|
### Phase 1.3: Session Revocation and Token Management
|
|
- ✅ JWT access tokens (15-minute TTL)
|
|
- ✅ Refresh tokens (7-day TTL) with rotation
|
|
- ✅ Device fingerprinting for security
|
|
- ✅ Token blacklist for immediate revocation
|
|
- ✅ Session management (list, revoke individual, revoke all)
|
|
- ✅ Audit logging for all authentication events
|
|
|
|
## Architecture
|
|
|
|
### Database Schema
|
|
- **users**: User accounts with encrypted email, name, 2FA secrets + JSON data column
|
|
- **sessions**: Active sessions for revocation
|
|
- **refresh_tokens**: Refresh tokens with device fingerprinting
|
|
- **token_blacklist**: Immediate token revocation
|
|
- **affiliate_accounts** (current app), **affiliates** (legacy), **withdrawals**, **feature_requests**, **contact_messages**
|
|
- **audit_log**: Comprehensive security event logging
|
|
- **payment_sessions**: DoDo payment tracking
|
|
|
|
### Encryption
|
|
- **Database**: SQLCipher encryption at rest
|
|
- **Algorithm**: AES-256-GCM with authenticated encryption (field-level)
|
|
- **Key Derivation**: PBKDF2 with 100,000 iterations
|
|
- **Per-field**: Sensitive fields encrypted individually
|
|
- **Token Storage**: PBKDF2 hashed (not encrypted) for secure comparison
|
|
|
|
### Token Management
|
|
- **Access Token**: JWT with 15-minute expiration
|
|
- **Refresh Token**: 128-byte random token, hashed with PBKDF2
|
|
- **Device Fingerprint**: SHA-256 hash of user agent, IP, language
|
|
- **Token Rotation**: New refresh token issued on every use
|
|
- **Blacklist**: Immediate revocation via token blacklist
|
|
|
|
## Container Deployment
|
|
|
|
The database is automatically initialized when the container starts:
|
|
|
|
1. **First deployment**: Database and encryption keys are automatically generated
|
|
2. **Subsequent deployments**: Uses existing database and keys
|
|
3. **JSON fallback**: Set `USE_JSON_DATABASE=1` to use legacy JSON files
|
|
|
|
### Environment Variables
|
|
|
|
Required:
|
|
```bash
|
|
DATABASE_ENCRYPTION_KEY=<64-character-hex-string> # Generate with: openssl rand -hex 32
|
|
JWT_SECRET=<64-character-hex-string> # Generate with: openssl rand -hex 32
|
|
```
|
|
|
|
Optional:
|
|
```bash
|
|
USE_JSON_DATABASE=1 # Use JSON files instead of database (for rollback)
|
|
DATABASE_PATH=./.data/shopify_ai.db
|
|
DATABASE_KEY_FILE=./.data/.encryption_key
|
|
DATABASE_BACKUP_ENABLED=1
|
|
DATABASE_WAL_MODE=1
|
|
DATABASE_USE_SQLCIPHER=1
|
|
DATABASE_CIPHER_COMPAT=4
|
|
DATABASE_KDF_ITER=64000
|
|
JWT_ACCESS_TOKEN_TTL=900 # 15 minutes in seconds
|
|
JWT_REFRESH_TOKEN_TTL=604800 # 7 days in seconds
|
|
```
|
|
|
|
### Automatic Setup
|
|
|
|
On container startup, the entrypoint script automatically:
|
|
1. Checks if database exists
|
|
2. Generates encryption keys if not provided (and saves them)
|
|
3. Runs database setup if needed
|
|
4. Notifies about migration if JSON files exist
|
|
|
|
## Manual Operations
|
|
|
|
### Initial Setup
|
|
```bash
|
|
# Inside the container or locally
|
|
cd /opt/webchat
|
|
node scripts/setup-database.js
|
|
```
|
|
|
|
### Migration from JSON
|
|
```bash
|
|
# Migrate existing JSON data to database
|
|
cd /opt/webchat
|
|
node scripts/migrate-to-database.js
|
|
|
|
# This will:
|
|
# - Create a backup of JSON files
|
|
# - Migrate users, sessions, affiliates
|
|
# - Report success/failure counts
|
|
```
|
|
|
|
### Rollback to JSON
|
|
```bash
|
|
# Set environment variable
|
|
export USE_JSON_DATABASE=1
|
|
|
|
# Restart the service
|
|
# The system will automatically use JSON files
|
|
```
|
|
|
|
## Security Features
|
|
|
|
### Encryption at Rest
|
|
- Database-level: SQLite with WAL mode
|
|
- Field-level: AES-256-GCM for sensitive fields
|
|
- Key management: PBKDF2 key derivation
|
|
- Token storage: PBKDF2 hashed (not reversible)
|
|
|
|
### Session Security
|
|
- Short-lived tokens: 15-minute access tokens
|
|
- Token rotation: New refresh token on every use
|
|
- Device binding: Tokens bound to device fingerprint
|
|
- Theft detection: Automatic revocation on fingerprint mismatch
|
|
- Immediate revocation: Token blacklist for instant logout
|
|
|
|
### Audit Trail

|
|
|
|
## Testing
|
|
|
|
### Verify Database Setup
|
|
```bash
|
|
# Check database exists and tables are created (SQLCipher)
|
|
sqlcipher ./.data/shopify_ai.db "PRAGMA key = '$DATABASE_ENCRYPTION_KEY'; .tables"
|
|
|
|
# Should output:
|
|
# affiliate_accounts payment_sessions token_blacklist
|
|
# affiliates refresh_tokens users
|
|
# audit_log sessions withdrawals
|
|
# contact_messages feature_requests
|
|
```
|
|
|
|
### Test Encryption
|
|
```bash
|
|
# Run setup (includes encryption test)
|
|
node scripts/setup-database.js
|
|
```
|
|
|
|
### Test Migration
|
|
```bash
|
|
# With test data
|
|
node scripts/migrate-to-database.js
|
|
```
|
|
|
|
## Monitoring
|
|
|
|
### Database Health
|
|
- Check file size: `ls -lh ./.data/shopify_ai.db`
|
|
- Check WAL mode: `sqlcipher ./.data/shopify_ai.db "PRAGMA key = '$DATABASE_ENCRYPTION_KEY'; PRAGMA journal_mode;"`
|
|
- Check tables: `sqlcipher ./.data/shopify_ai.db "PRAGMA key = '$DATABASE_ENCRYPTION_KEY'; .tables"`
|
|
|
|
### Audit Logs
|
|
Audit logs are stored in the `audit_log` table and include:
|
|
- User authentication events (login, logout, refresh)
|
|
- Session management (create, revoke)
|
|
- Token events (blacklist, rotation)
|
|
- IP addresses and user agents
|
|
|
