Question 1

What is an SSL/TLS Certificate?

Accepted Answer

SSL/TLS (Secure Sockets Layer / Transport Layer Security) encrypts communication between a user's web browser and the server, enabling HTTPS and displaying the security padlock icon.

Question 2

What happens if an SSL Certificate expires?

Accepted Answer

When a certificate expires, browsers show severe security warnings blocking user access, destroying user trust, and harming Google SEO rankings.

Question 3

What is a Certificate Chain of Trust?

Accepted Answer

The certificate chain links your server certificate through intermediate certificates up to a trusted Root Certificate Authority (CA) pre-installed in operating systems.

Question 4

What is the difference between TLS 1.2 and TLS 1.3?
