## ⚠️ ISSUES REQUIRING ATTENTION

### Issue #1: Hardcoded Default Values in Config 🔴

**Location**: `app/config.py`

**Problem**:
```python
SECRET_KEY = os.getenv('SECRET_KEY', 'dev-secret-key-change-in-production')
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', 'Initial01!')
```

**Risk**: Default values will be used if environment variables not set

**Solution** (Choose one):

**Option A: Remove defaults (Recommended)**
```python
SECRET_KEY = os.getenv('SECRET_KEY')  # Fails fast if not set
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD')
```

**Option B: Use stronger defaults**
```python
import secrets
SECRET_KEY = os.getenv('SECRET_KEY', secrets.token_urlsafe(32))
DEFAULT_ADMIN_PASSWORD = os.getenv('ADMIN_PASSWORD', secrets.token_urlsafe(16))
```

---

### Issue #2: Uncommitted Changes 🟡

**Current status**: 7 uncommitted changes

```
 M app/app.py                 (CORS implementation)
 M app/blueprints/api.py      (Certificate endpoint)
 M app/config.py              (Session security)
 M app/extensions.py          (CORS support)
 M nginx.conf                 (CORS headers)
 M requirements.txt           (Added cryptography)
 ? old_code_documentation/    (New documentation)
```

**Action Required**:
```bash
cd /srv/digiserver-v2
git add -A
git commit -m "HTTPS improvements: Enable CORS, fix player connections, add security headers"
git log --oneline -1
```

## 🚀 PRODUCTION DEPLOYMENT CHECKLIST

### Pre-Deployment (Execute in order)

- [ ] **1. Commit all changes**
  ```bash
  git status
  git add -A
  git commit -m "Production-ready: HTTPS/CORS fixes"
  ```

- [ ] **2. Set environment variables**
  Create `.env` file or configure in deployment system:
  ```bash
  SECRET_KEY=<generate-long-random-string>
  ADMIN_USERNAME=admin
  ADMIN_PASSWORD=<strong-password>
  ADMIN_EMAIL=admin@yourdomain.com
  DATABASE_URL=sqlite:////path/to/db  # or PostgreSQL
  FLASK_ENV=production
  DOMAIN=your-domain.com
  EMAIL=admin@your-domain.com
  ```

- [ ] **3. Update docker-compose.yml environment section**
  ```yaml
  environment:
    - FLASK_ENV=production
    - SECRET_KEY=${SECRET_KEY}
    - ADMIN_USERNAME=${ADMIN_USERNAME}
    - ADMIN_PASSWORD=${ADMIN_PASSWORD}
    - DATABASE_URL=${DATABASE_URL}
    - DOMAIN=${DOMAIN}
    - EMAIL=${EMAIL}
  ```

- [ ] **4. SSL Certificate Strategy**
  
  **Option A: Keep Self-Signed (Quick)**
  - Current certificate valid until 2027
  - Players must accept/trust cert
  - Suitable for internal networks
  
  **Option B: Use Let's Encrypt (Recommended)**
  - Install certbot: `apt install certbot`
  - Generate cert: `certbot certonly --standalone -d yourdomain.com`
  - Copy to: `data/nginx-ssl/`
  - Auto-renew with systemd timer
  
  **Option C: Use Commercial Certificate**
  - Purchase from provider
  - Copy cert and key to `data/nginx-ssl/`
  - Update nginx.conf paths if needed

- [ ] **5. Database initialization**
  ```bash
  # First run will create database
  docker-compose up -d
  # Run migrations
  docker-compose exec digiserver-app flask db upgrade
  ```

- [ ] **6. Test deployment**
  ```bash
  # Health check
  curl -k https://your-server/api/health
  
  # CORS headers
  curl -i -k https://your-server/api/playlists
  
  # Login page
  curl -k https://your-server/login
  ```

- [ ] **7. Backup database**
  ```bash
  docker-compose exec digiserver-app \
    cp instance/dashboard.db /backup/dashboard.db.bak
  ```

- [ ] **8. Configure monitoring**
  - Set up log aggregation
  - Configure alerts for container restarts
  - Monitor disk space for uploads

### Post-Deployment

- [ ] Verify player connections work
- [ ] Test playlist fetching
- [ ] Monitor error logs for 24 hours
- [ ] Verify database backups are working
- [ ] Set up SSL renewal automation

## 🔒 SECURITY RECOMMENDATIONS

### Before Going Live

1. **Change all default passwords**
   - [ ] Admin initial password
   - [ ] Database password (if using external DB)

2. **Rotate SSL certificates**
   - [ ] Replace self-signed cert with Let's Encrypt or commercial
   - [ ] Set up auto-renewal

3. **Enable HTTPS only**
   - [ ] Redirect all HTTP to HTTPS (already configured)
   - [ ] Set HSTS header (consider adding)

4. **Secure the instance**
   - [ ] Close unnecessary ports
   - [ ] Firewall rules for 80 and 443 only
   - [ ] SSH only with key authentication
   - [ ] Regular security updates

5. **Database Security**
   - [ ] Regular backups (daily recommended)
   - [ ] Test backup restoration
   - [ ] Restrict database access

6. **Monitoring**
   - [ ] Enable application logging
   - [ ] Set up alerts for errors
   - [ ] Monitor resource usage
   - [ ] Check SSL expiration dates
