## Key Features Implemented

### ✅ Automatic Certificate Management
- Player automatically downloads server certificate on first connection
- Certificate stored locally in `~/.kiwy-signage/`
- Subsequent connections use saved certificate

### ✅ Secure Authentication
- All authentication now uses HTTPS
- Automatic URL scheme normalization to HTTPS
- SSL certificate verification (configurable)

### ✅ HTTPS Playlist Operations
- Playlist fetching over HTTPS
- Media file downloads over HTTPS
- Status feedback via HTTPS

### ✅ Configurable Security
- `use_https` setting to enable/disable HTTPS
- `verify_ssl` setting for certificate verification
- Development mode support (without verification)

### ✅ Robust Error Handling
- SSL-specific error messages
- Graceful fallbacks
- Comprehensive logging

---

## Configuration

### Minimal Setup (Using Defaults)
```json
{
  "server_ip": "digi-signage.moto-adv.com",
  "port": "443",
  "screen_name": "tv-terasa",
  "quickconnect_key": "8887779",
  "use_https": true,
  "verify_ssl": true
}
```

### For Testing (Without SSL Verification)
```json
{
  "use_https": true,
  "verify_ssl": false
}
```

### For HTTP (Development Only)
```json
{
  "use_https": false,
  "verify_ssl": false,
  "port": "5000"
}
```

---

## Testing & Verification

### ✅ Syntax Validation
- All Python files compile without errors
- All JSON configurations are valid
- No import errors

### ✅ Integration Points
- Player authentication with HTTPS ✓
- Playlist fetching with HTTPS ✓
- Media downloads with HTTPS ✓
- Status feedback via HTTPS ✓
- Certificate management ✓

### ✅ Backward Compatibility
- Existing HTTP deployments still work (`use_https: false`)
- Legacy configuration loading still supported
- All changes are non-breaking

---

## Deployment Instructions

### Step 1: Update Configuration
Edit `config/app_config.json` and ensure:
```json
{
  "use_https": true,
  "verify_ssl": true,
  "port": "443"
}
```

### Step 2: Restart Application
```bash
cd /home/pi/Desktop/Kiwy-Signage
./stop_player.sh
./start.sh
```

### Step 3: Verify Functionality
- Monitor logs for SSL messages
- Check certificate is saved: `ls ~/.kiwy-signage/`
- Test playlist fetch works
- Confirm all API calls succeed

### Step 4: Monitor
- Watch for SSL-related errors in first hours
- Verify performance is acceptable
- Monitor certificate expiration if applicable

## Troubleshooting Quick Links

| Issue | Solution |
|-------|----------|
| `SSL: CERTIFICATE_VERIFY_FAILED` | See HTTPS_QUICK_REFERENCE.md - Troubleshooting |
| Connection refused on 443 | Check HTTPS is enabled on server |
| Certificate endpoint 404 | Verify `/api/certificate` exists on server |
| Slow HTTPS | Increase timeout in player_auth.py |

See `HTTPS_QUICK_REFERENCE.md` for detailed troubleshooting.
