/**
 * HTTPS Server Example
 *
 * This is an example demonstrating how to use the generated X509 certificate
 * in a Node.js HTTPS server.
 *
 * Usage:
 * 1. Generate a certificate using the X509 Certificate Generator tool
 * 2. Save the certificate as 'certificate.crt' and private key as 'privateKey.key'
 * 3. Create a 'cert' folder in your project root
 * 4. Place the files in the cert folder
 * 5. Run this file with: ts-node https-server-example.ts
 * 6. Access the server at: https://localhost:8443
 *
 * Note: Since this is a self-signed certificate, your browser will show a security warning.
 * You can proceed safely for development/testing purposes.
