TLS tool

SSL certificate checker

Inspect the certificate a website presents on HTTPS and check its expiry, issuer, names and TLS connection details.

Quick guide

What this SSL check tells you

A valid HTTPS certificate should be trusted, match the hostname you requested and be within its validity period. IPGetter connects directly to the public IP resolved for the hostname and inspects the certificate presented on port 443.

This is a point-in-time check from the IPGetter server. CDNs and load balancers can present different certificates from different network locations.

Verified

The certificate trust chain and hostname check passed during the TLS connection.

Expiry

Certificates must be renewed before their valid-until date or browsers will show security warnings.

SANs

Subject Alternative Names list the hostnames covered by the certificate.

How it works

IPGetter opens a TLS connection to the host, verifies the certificate chain and hostname, then reports the certificate, negotiated TLS version, cipher and handshake timing.
