Check SSL
Chain Hierarchy
This SSL Checker verifies your live SSL certificate and shows expiry date, certificate chain, subject information, SANs, TLS configuration and server response. It works with any domain, including subdomains and custom ports (example: domain.com:8443).
No data is stored — scanning is done only to retrieve certificate information and then discarded.
How to use
- Enter your domain (example: vinar.tech)
- Click “Check SSL”
- Wait for the SSL scan to complete
- View expiry date, server info, chain, SANs, protocol & grade
- Export your SSL report as TXT or JSON
