# HTTPS Management System - Implementation Summary

## ✅ What Has Been Implemented

A complete HTTPS configuration management system has been added to DigiServer v2, allowing administrators to manage HTTPS settings through the web interface.

### Files Created

#### 1. **Database Model** (`app/models/https_config.py`)
- New `HTTPSConfig` model for storing HTTPS configuration
- Fields: hostname, domain, ip_address, port, enabled status, audit trail
- Methods: `get_config()`, `create_or_update()`, `to_dict()`

#### 2. **Admin Routes** (updated `app/blueprints/admin.py`)
- `GET /admin/https-config` - Display configuration page
- `POST /admin/https-config/update` - Update settings
- `GET /admin/https-config/status` - Get status as JSON
- Full validation and error handling
- Admin-only access with permission checks

#### 3. **Admin Template** (`app/templates/admin/https_config.html`)
- Beautiful, user-friendly configuration interface
- Status display showing current HTTPS settings
- Form with toggle switch for enable/disable
- Input fields for: hostname, domain, IP address, port
- Real-time preview of access points
- Comprehensive help text and information sections
- Responsive design for mobile compatibility

#### 4. **Database Migration** (`migrations/add_https_config_table.py`)
- Creates `https_config` table with all necessary fields
- Indexes on important columns
- Timestamps for audit trail

#### 5. **Admin Dashboard Link** (updated `app/templates/admin/admin.html`)
- Added new card in admin dashboard linking to HTTPS configuration
- Purple gradient card with lock icon (🔒)
- Easy access from main admin panel

#### 6. **CLI Utility** (`https_manager.py`)
- Command-line interface for managing HTTPS configuration
- Commands: `status`, `enable`, `disable`, `show`
- Useful for automation and scripting

#### 7. **Setup Script** (`setup_https.sh`)
- Automated setup script for database migration
- Step-by-step instructions for configuration

#### 8. **Documentation** (`HTTPS_CONFIGURATION.md`)
- Comprehensive guide covering:
  - Feature overview
  - Step-by-step workflow
  - Configuration details
  - Prerequisites
  - Integration details
  - Troubleshooting
  - Examples

### Files Updated

#### 1. **Models Package** (`app/models/__init__.py`)
- Added import for `HTTPSConfig`
- Exported in `__all__` list

#### 2. **Admin Blueprint** (`app/blueprints/admin.py`)
- Imported `HTTPSConfig` model
- Added HTTPS management routes

#### 3. **Admin Dashboard** (`app/templates/admin/admin.html`)
- Added link to HTTPS configuration

#### 4. **Caddyfile**
- Already preconfigured with domain: `digiserver.sibiusb.harting.intra`
- IP fallback: `10.76.152.164`
- Ready to use with the new configuration system

## 🚀 Quick Start Guide

### Step 1: Database Setup
```bash
# Run the migration to create the https_config table
python /app/migrations/add_https_config_table.py

# Or automatically with the setup script
bash setup_https.sh
```

### Step 2: Start the Application (HTTP Only)
```bash
docker-compose up -d
```

### Step 3: Configure HTTPS via Admin Panel
1. Log in as admin
2. Go to: **Admin Panel → 🔒 HTTPS Configuration**
3. Toggle "Enable HTTPS"
4. Fill in:
   - Hostname: `digiserver`
   - Domain: `digiserver.sibiusb.harting.intra`
   - IP Address: `10.76.152.164`
   - Port: `443` (default)
5. Click "Save HTTPS Configuration"

### Step 4: Verify Access
- HTTPS: `https://digiserver.sibiusb.harting.intra`
- HTTP Fallback: `http://10.76.152.164`

## 📋 Workflow Explanation

### Initial State (HTTP Only)
```
┌─────────────────┐
│ App Running on  │
│ Port 80 (HTTP)  │
└────────┬────────┘
         │
         └─ Accessible at: http://10.76.152.164
```

### After Configuration (HTTP + HTTPS)
```
┌──────────────────────────────────────┐
│ Admin Configures HTTPS Settings:     │
│ • Hostname: digiserver               │
│ • Domain: digiserver...intra          │
│ • IP: 10.76.152.164                  │
│ • Port: 443                          │
└──────────────┬───────────────────────┘
               │
       ┌───────┴────────┐
       │                │
  ┌────▼────┐    ┌─────▼──────┐
  │ HTTPS   │    │ HTTP       │
  │ Port443 │    │ Port 80    │
  └────┬────┘    └─────┬──────┘
       │              │
       └──────────────┘
         Both available
```
