A Python script that generates QR codes containing authentication data (URL and secret key) and displays them both in the terminal and as image files.

Features

• Generates QR codes with authentication data (URL and secret key)
• Displays QR code directly in the terminal
• Saves QR code as PNG image file
• Uses functional programming principles

Requirements

• Python 3.6+
• qrcode library
• qrcode-terminal library

Installation

1. Clone this repository:

git clone https://github.com/Egregore-ai/generate-qr-code
cd generate-qr-code

2. Install required packages:

pip install qrcode qrcode-terminal

Usage

Run the script directly:

python main.py

The script will:

1. Generate a random secret key
2. Create a JSON payload with the URL and secret key
3. Display the QR code in the terminal
4. Save the QR code as auth_qr.png in the current directory

Customization

You can modify the url and secret_key values in the if __name__ == "__main__": block to customize the authentication data.

API

The script provides several functions for generating QR codes:

• create_auth_qr_data(url, secret_key): Creates a JSON payload containing the URL and secret key
• generate_qr_code(data): Generates a QR code (as PNG bytes) from input string data
• qr_pipeline(url, secret_key): End-to-end pipeline that returns both JSON payload and QR image bytes
