A network configuration generator and validator for network engineers.

• Multi-vendor support: Generate configurations for Cisco IOS/IOS-XE, NX-OS, Arista EOS, and Juniper Junos
• Configuration validation: Catch errors and get best-practice recommendations before deployment
• Import & analyze: Parse existing configurations and identify issues
• Secure vault: Encrypted storage for credentials and sensitive variables
• Modern GUI: Clean, dark-themed interface using CustomTkinter

# Clone the repository
cd netconfigpro

# Create virtual environment (recommended)
python3 -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements.txt

# Run the application
python main.py
