What is HTTPS and what is HTTP?
HTTP: Hypertext Transfer Protocol
The fundamental protocol used by the World Wide Web, it has been present since the beginning when the internet was developed. It defines how data are formatted and transmitted, giving users a way to interact with Web resources.
HTTPS: Hypertext Transfer Protocol Secure
HTTPS is HTTP with an SSL certificate.
SSL Certificate (Secure Sockets Layer)
(Yes, another confusing acronym but just bear with us!)
An SSL Certificate is a set of data files that you can add to your server to achieve an encrypted connection between a browser and your server. Having an HTTPS in the address bar of your browser means that all communication with this website will be encrypted.
