Use toolHow the SSL checker works
Check any SSL certificate online in three simple steps — no signup, no downloads.

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.
