TLS explained simply | SSL Certificate, Certificate Authority, Chain Of Trust explained with example

Ever wondered how the little lock in your browser's URL ensures a secure connection, or what exactly is SSL/TLS?
This video explains how a client establishes a trusted HTTPS connection with a remote server using a simple example.

We see what roles SSL Certificates, Certificate Authorities (CAs) and Certificate Stores play in this, and how a chain of trust allows Intermediate Certificate Authorities to give out certificates on a Root CA's behalf.

A quick demo shows how this works with our browser.
