What is the difference between SSL and TLS?
SSL is the historical term. In practice, HTTPS uses TLS today, but people still search for “SSL”.

Understanding SSL/TLS
Read a certificate without giving it more power than it has
SSL is still the public term people search for, while TLS is the protocol actually used by HTTPS. This page reads the certificate presented on port 443 and summarizes the useful details.
- The expiration date tells you when the certificate will stop being valid.
- SAN names can cover several domains, and they take precedence over the common name.
- A trusted chain does not prove that a site is honest or safe to use.
- A self-signed or misaligned certificate deserves caution, even if the site responds.

SSL FAQ
Frequently asked SSL/TLS questions
Does a valid certificate guarantee a trustworthy site?
No. It only guarantees that a recognised certificate covers the requested name and that it is not expired.
Why can the site show “domain not covered”?
The certificate presented on 443 does not include the requested name in its SANs or in its primary name.
Why do some results mention an untrusted chain?
The browser or PHP could not validate the chain up to a recognised authority.
