Frequently Asked Questions

What is an SSL certificate?

An SSL certificate helps establish a secure encrypted connection between a website and its visitors.

What does HTTPS mean?

HTTPS is the secure version of HTTP and uses encryption to protect data exchanged between the browser and a website.

Can a browser directly read every website's SSL expiration date?
