"""
Test script to verify pyOpenSSL update doesn't break crawl4ai functionality.

This test verifies:
1. pyOpenSSL and cryptography versions are correct and secure
2. Basic crawling functionality still works
3. HTTPS/SSL connections work properly
4. Stealth mode integration works (uses playwright-stealth internally)

Issue: #1545 - Security vulnerability in cryptography package
Fix: Updated pyOpenSSL from >=24.3.0 to >=25.3.0
Expected: cryptography package should be >=45.0.7 (above vulnerable range)
