License Generator

🚀 Overview

This is a simple License Generator that allows users to generate signed licenses for domains or clients. It uses RSA encryption to sign the license and stores the data securely in an SQLite database. The application runs as a lightweight HTTP server, serving a simple HTML form for user input.

📌 Features

• No external frameworks required (uses built-in Python modules)
• Generates signed licenses using RSA encryption
• Stores license details in SQLite for persistence
• Lightweight HTTP server for handling form submissions
• Simple web interface for license generation

📦 Requirements

• Python 3.x
• SQLite (built-in with Python)
• No additional dependencies

🛠 Installation & Setup

1️⃣ Clone the Repository

git clone https://github.com/yourusername/license-generator.git
cd license-generator

2️⃣ Run the Script

python licence.py

3️⃣ Open in Browser

Go to http://localhost:8080 in your web browser to access the License Generator form.

🎯 How It Works

1. User fills out the form (Client ID, License Type, Duration).
2. Python server processes the request, signs the license, and stores it in SQLite.
3. Generated license is displayed on the page and stored in the database.

🔑 License Data Format

Each generated license contains:

{
    "client_id": "example.com",
    "license_type": "Pro",
    "exp": 1729296000,
    "issued_at": 1710748800
}

• client_id: The domain or name of the client
• license_type: Type of license (Basic, Pro, Enterprise)
• exp: Expiry timestamp
• issued_at: Issued timestamp
• signature: RSA-signed string (stored in the database)

🏗 Database Schema (SQLite)

CREATE TABLE licenses (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    client_id TEXT UNIQUE NOT NULL,
    license_type TEXT NOT NULL,
    issued_at INTEGER NOT NULL,
    exp INTEGER NOT NULL,
    signature TEXT NOT NULL
);

🛑 Stopping the Server

Press CTRL + C in the terminal to stop the server.
