We all know that HTTP stands for "Hyper Text Transfer Protocol". Then you must be curious to know what is HTTPS, HTTPS stands for "Hyper Text Transfer Protocol Secure" or Hyper Text Transfer Protocol over Secure Socket Layer, or HTTP over SSL. When a user connects to a website via HTTPS, the website encrypts the session with a digital certificate.HTTPS should not be confused with S-HTTP, a security-enhanced version of HTTP. SSL and S-HTTP have very different designs and goals so it is possible to use the two protocols together.
Whereas SSL is designed to establish a secure connection between two computers, S-HTTP is designed to send individual messages securely. Now this question must arise in our minds that what is SSL and how it works and why it is required in websites.

Secure Sockets Layer uses a cryptographic system that encrypts data with two keys.When a SSL Digital Certificate is installed on a web site, users can see a padlock icon at the bottom area of the navigator. When an Extended Validation Certificates is installed on a web site, users with the latest versions of Firefox, Internet Explorer or Opera will see the green address bar at the URL area of the navigator.SSL is required because with booming Internet trends and fraud, most will not submit their private details on the web unless they know that the information they provide is securely transmitted and not accessible for anyone to view,so websites install SSL certificate so that they become more secure,these protocols are mostly used in bank and shopping sites but now a days every sites which intend user to submit their private data on web uses SSL certification so that user can know that the data they are submitting is secure.
