How the SSL checker works
Check any SSL certificate online in three simple steps — no signup, no downloads.
1. Enter a hostname
Type any domain or subdomain — for example example.com or mail.example.com. You can paste a full URL; we'll clean it up automatically. Add :port for non-standard ports.
2. We connect live
RunSSLCheck opens a real TLS connection to the server and inspects the exact certificate it presents — no cached data and no third-party API.
3. Read your results
See trust status, hostname match, expiry countdown, the full certificate chain, key strength, and which TLS versions are enabled.
