Check SSL Certificate

â„šī¸ How It Works

This tool simulates SSL certificate checking using mock data. In a production environment, it would connect to the domain's SSL endpoint to retrieve and validate the certificate chain, check expiry dates, and verify security configurations.

🔒 SSL Security Tips

Renew Early

Renew certificates at least 30 days before expiry to avoid service disruption.

Use Strong Keys

Use at least 2048-bit RSA or 256-bit ECDSA keys for better security.

Enable HSTS
