How It Works
Type your website domain, for example example.com, or include a port like mail.example.com:993. The tool will check the SSL certificate and show:

- ❌ SSL certificate expired or invalid
- ⏳ Days remaining until expiration

SSL certificate expiration can lead to browser warnings, loss of trust, and even temporary downtime. Regularly monitoring your certificates ensures uninterrupted security and a smooth experience for your visitors.
