Installation

1. Clone the Repository:

   git clone https://github.com/Popinek/lemonsqueezyLicense.git
   cd lemonsqueezyLicense

   pip install -r requirements.txt

3. Set Environment Variables: Create a .env file in the root directory and add your URL:

   URL=https://example.com/validate
   

Usage

Command-Line Interface

1. Run the Script:

   python client.py

   • The script will prompt for a license key.
   • It will attempt to activate and validate the key.
   • HWID validation is performed after successful license activation.
   • If successful, it will save the key and run the main script functionality.

2. License Key Activation:

   • Enter your license key when prompted.
   • Type 'quit' to exit the program.

3. Main Script:

   • Replace the placeholder main_script function with your actual application logic.

Flask Web Server

1. Run the Flask Application:

   python app.py

   • By default, the Flask server will run on port 5000.

2. Validate License Key via API:

   • Send a POST request to http://127.0.0.1:5000/validate with JSON payload:

     {
       "activation_key": "your_license_key_here"
     }

   • Response will be in JSON format indicating whether the license key is valid or not.
   • If HWID mismatch occurs, access is denied.

API Endpoint

• POST /validate

  Request Body:

  {
    "activation_key": "string"
  }

  Response:

    {
      "status": "success",
      "message": "License key and HWID matches!"
    }

  or

    {
      "status": "success",
      "message": "License key and HWID added successfully"
    }

  or

    {
      "status": "error",
      "message": "HWID mismatch"
    }
