SSL Auditor

Validity, expiry windows, TLS protocol versions and trust-chain checks against the live certificate.

How this works - what gets checked, in plain English

What we probe: any HTTPS-enabled domain. We open a TLS connection to port 443 and read the certificate your server presents. It's the same handshake every browser does to talk to you.
Where we look: the certificate's expiry date, issuer trust chain, TLS protocol version (1.2 / 1.3 / older), cipher strength, and HSTS / OCSP stapling status.
What "expiring" or "weak" means: browsers show scary security warnings, Google penalises your SEO, and modern clients may refuse to connect at all.
What we don't do: we don't decrypt traffic or extract keys. Nothing more than a public TLS handshake. The same one every visitor's browser does anyway.
