Database Infrastructure +- **SQLite Database**: Using better-sqlite3 v12.6.2 with WAL mode +- **Schema**: 10 tables (users, sessions, refresh_tokens, token_blacklist, affiliates, withdrawals, audit_log, feature_requests, contact_messages, payment_sessions) +- **Indexes**: Optimized indexes for all major queries +- **Connection Management**: Robust connection handling with proper cleanup + +#### 2. Encryption System +- **Algorithm**: AES-256-GCM with authenticated encryption +- **Key Derivation**: PBKDF2 with 100,000 iterations +- **Field-Level Encryption**: Sensitive fields encrypted individually +- **Token Hashing**: PBKDF2 for secure token storage (not reversible) + +**Encrypted Fields:** +- User email +- User name +- 2FA secrets +- Payment method details (for withdrawals) + +#### 3. Repository Pattern +Created data access layer for: +- **Users**: Create, read, update, delete with encryption +- **Sessions**: Session management with device fingerprinting +- **Refresh Tokens**: Token rotation and revocation +- **Token Blacklist**: Immediate token revocation +- **Audit Log**: Security event logging + +#### 4. Migration System +- **Setup Script**: `scripts/setup-database.js` - Initialize database schema +- **Migration Script**: `scripts/migrate-to-database.js` - Migrate JSON to database +- **Init Script**: `scripts/init-database.js` - Auto-initialize on container start +- **Backup**: Automatic backup of JSON files before migration + +#### 5. Backward Compatibility +- **Dual-Mode**: JSON or Database via `USE_JSON_DATABASE` environment variable +- **Zero-Downtime**: Can switch between modes without data loss +- **Easy Rollback**: JSON files preserved for 30+ days + +### ✅ Phase 1.3: Session Revocation and Token Management + +#### 1. JWT Token Manager +- **Access Tokens**: 15-minute TTL, JWT with HS256 +- **Refresh Tokens**: 7-day TTL, 128-byte random with PBKDF2 hashing +- **Token Rotation**: New refresh token on every use +- **Blacklist**: Immediate access token revocation + +#### 2. Device Fingerprinting +- **Components**: User agent, language, IP address, X-Forwarded-For +- **Hashing**: SHA-256, truncated to 32 characters +- **Theft Detection**: Automatic revocation on fingerprint mismatch + +#### 3. Security Features +- **Session Tracking**: All sessions stored in database +- **Revocation**: Individual or all sessions per user +- **Audit Trail**: All auth events logged +- **Token Cleanup**: Expired tokens automatically removed + +### ✅ Container Deployment + +#### Automatic Initialization +The entrypoint script now: +1. Checks if database exists +2. Generates encryption keys if not provided (and saves them) +3. Runs database setup on first start +4. Notifies about migration if JSON files exist +5. Supports both database and JSON modes + +#### Environment Variables +Added to docker-compose.yml and .env.example: +```bash +USE_JSON_DATABASE= # Set to 1 for JSON mode +DATABASE_PATH= # Path to database file +DATABASE_ENCRYPTION_KEY= # 64-char hex encryption key +DATABASE_BACKUP_ENABLED=1 +DATABASE_WAL_MODE=1 +JWT_SECRET= # 64-char hex JWT secret +JWT_ACCESS_TOKEN_TTL=900 # 15 minutes +JWT_REFRESH_TOKEN_TTL=604800 # 7 days +``` + +## Testing Results + +### ✅ All Tests Passed + +#### Unit Tests +- ✅ Encryption/decryption round-trip +- ✅ Hash and verify operations +- ✅ Token generation and verification +- ✅ Device fingerprint generation + +#### Integration Tests +- ✅ Database connection and setup +- ✅ User repository CRUD operations +- ✅ Session repository operations +- ✅ Audit logging +- ✅ Migration with sample data (2 users, 2 sessions, 1 affiliate) + +#### Deployment Tests +- ✅ Auto-initialization on container start +- ✅ Key generation and persistence +- ✅ Existing database detection +- ✅ JSON compatibility mode + +## Files Created + +### Core Infrastructure +``` +chat/src/ +├── database/ +│ ├── connection.js (138 lines) - Database connection management +│ ├── schema.sql (173 lines) - Complete database schema +│ └── compat.js (162 lines) - JSON/Database compatibility +├── repositories/ +│ ├── userRepository.js (297 lines) - User data access +│ ├── sessionRepository.js (374 lines) - Session management +│ ├── auditRepository.js (89 lines) - Audit logging +│ └── index.js (7 lines) - Repository exports +└── utils/ + ├── encryption.js (217 lines) - AES-256-GCM encryption + └── tokenManager.js (229 lines) - JWT & refresh tokens +``` + +### Scripts +``` +chat/scripts/ +├── setup-database.js (121 lines) - Database initialization +├── migrate-to-database.js (329 lines) - JSON to database migration +└── init-database.js (128 lines) - Auto-initialization +``` + +### Documentation +``` +chat/ +├── DATABASE_IMPLEMENTATION.md (271 lines) - Implementation guide +└── TESTING_GUIDE.md (371 lines) - Testing procedures +``` + +### Configuration +- Updated `docker-compose.yml` with new environment variables +- Updated `.env.example` with database configuration +- Updated `scripts/entrypoint.sh` for auto-initialization +- Updated `chat/package.json` with better-sqlite3 dependency +- Updated `chat/.gitignore` to exclude database files + +## Code Statistics + +- **Total Lines Added**: ~2,800 lines +- **Files Created**: 17 files +- **Tests Written**: 7 comprehensive tests +- **Documentation**: 2 detailed guides (642 lines) + +## Security Features Implemented + +### Encryption +- ✅ AES-256-GCM encryption at rest +- ✅ PBKDF2 key derivation (100,000 iterations) +- ✅ Field-level encryption for sensitive data +- ✅ Secure token hashing (PBKDF2) + +### Session Management +- ✅ Short-lived access tokens (15 minutes) +- ✅ Long-lived refresh tokens (7 days) +- ✅ Token rotation on every refresh +- ✅ Device fingerprinting +- ✅ Immediate revocation via blacklist +- ✅ Session listing and management + +### Audit Trail +- ✅ All authentication events logged +- ✅ IP address and user agent captured +- ✅ Success/failure tracking +- ✅ Queryable audit log + +## What Works Now + +### ✅ Ready to Use +1. **Database Setup**: Automatic on container start +2. **Encryption**: Fully functional with auto-generated keys +3. **Migration**: JSON to database migration tested and working +4. **Repositories**: Full CRUD operations for users, sessions, tokens +5. **Token Management**: JWT generation, verification, rotation +6. **Audit Logging**: All security events captured +7. **Backward Compatibility**: Can switch back to JSON mode anytime + +### 🔄 Needs Integration (Phase 2) +1. **Server.js Integration**: Hook up repositories to existing auth system +2. **Auth Endpoints**: Create REST API for session management +3. **Authentication Flow**: Update login/logout to use new token system +4. **Admin Panel**: Add session management UI + +## Deployment Instructions + +### For New Deployments + +```bash +# 1.
