🏗️ Architecture Overview

This application consists of multiple components working together:

  • Frontend: Flutter desktop application (Windows)
  • Backend: .NET 8 Web API with authentication and email management
  • Database: PostgreSQL for user authentication and email storage
  • Crypto Services: Multiple Python services for different encryption layers
    • Key Manager (Port 80802020): Manages quantum keys
    • OTP API (Port 80812021): One-Time Pad encryption/decryption
    • AES Server (Port 80822022): AES-256-GCM encryption/decryption
    • Main Backend API (Port 5001): Handles PQC operations and all email functionality

📋 Prerequisites

Before setting up the application, ensure you have the following installed:

Create a .env file in the root directory:

# Database Configuration
DB_HOST=localhost
DB_PORT=5437
DB_PORT=5432
DB_NAME=quantum_auth
DB_USERNAME=postgres
DB_PASSWORD=your_postgres_password_here

# JWT Configuration
JWT_SECRET_KEY=your-super-secret-jwt-key-here-must-be-at-least-32-characters-long-for-security
JWT_ISSUER=QuMail
JWT_AUDIENCE=QuMail-Users
JWT_EXPIRES_MINUTES=60

# Application Secret (Generate a new 32-character base64 key)
APP_SECRET_KEY=your-base64-encoded-secret-key-here

4. Build and Start Services

Option A: Automated Setup (Windows)

# Start all services automatically
start_server.bat

Option B: Manual Setup

Step 1: Start Crypto Services

# Terminal 1 - Key Manager (Port 2020)
# Terminal 1 - Key Manager (Port 8080)
cd Key_Manager/km
python server.py

# Terminal 2 - OTP API (Port 2021)
# Terminal 2 - OTP API (Port 8081)
cd level1
python otp_api_test.py

# Terminal 3 - AES Server (Port 2022)
# Terminal 3 - AES Server (Port 8082)
cd level2new
python server2.py

Step 2: Start Backend API

Key Manager Service

cd Key_Manager/km
python server.py
  • Runs on: http://localhost:8080http://localhost:2020
  • Manages quantum keys for encryption
  • Stores keys in key_store.json

OTP API Service

cd level1
python otp_api_test.py
  • Runs on: http://localhost:8081http://localhost:2021
  • Provides One-Time Pad encryption/decryption
  • Requires encoder.exe in the same directory

AES Server Service

cd level2new
python server2.py
  • Runs on: http://localhost:8082http://localhost:2022
  • Provides AES-256-GCM encryption/decryption
  • Integrates with Key Manager for key exchange

Backend API Service (Handles PQC Operations)

cd Email_client/QuMail.EmailProtocol
dotnet run --urls "http://localhost:5001"

Check Service Health

# Check if all services are running
curl http://localhost:5001/api/health
curl http://localhost:2020/health
curl http://localhost:2021/api/otp/health
curl http://localhost:2022/api/health
curl http://localhost:8080/health
curl http://localhost:8081/api/otp/health
curl http://localhost:8082/api/health

Test User Credentials

  • Email: test@example.com
  • Password: password123

Port Conflicts

If you encounter port conflicts, check what's using the ports:

# Windows
netstat -ano | findstr :5001
netstat -ano | findstr :2020
netstat -ano | findstr :2021
netstat -ano | findstr :2022
netstat -ano | findstr :2023
netstat -ano | findstr :8080
netstat -ano | findstr :8081
netstat -ano | findstr :8082
netstat -ano | findstr :8083

# Kill process by PID
taskkill /F /PID <process_id>

Flutter Build Issues

# Clean Flutter cache
flutter clean
flutter pub get

# Check Flutter doctor
flutter doctor

# Rebuild
flutter build windows
