What is HTTPS?

Hyper Text Transfer Protocol Secure (HTTPS) is a secure version of the Hyper Text Transfer Protocol (http). HTTPS allows secure ecommerce transactions, such as online banking.
Web browsers such as Internet Explorer and Firefox display a padlock icon to indicate that the website is secure, as it also displays https:// in the address bar.
When a user connects to a website via HTTPS, the website encrypts the session with a Digital Certificate. A user can tell if they are connected to a secure website if the website URL begins with https:// instead of http://.

How Does SSL Work?

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.

Users on sites with SSL Certificates will also see https:// in the address bar during an ecommerce transaction.

Why Is A SSL Certificate Required?

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.

SSL

(pronounced as separate letters) Short for Secure Sockets Layer, aprotocol developed by Netscape for transmitting private documents via the Internet. SSL uses a cryptographic system that uses twokeys to encrypt data − a public key known to everyone and a private or secret key known only to the recipient of the message. BothNetscape Navigator and Internet Explorer support SSL, and manyWeb sites use the protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an SSL connection start with https: instead of http
:.
Another protocol for transmitting data securely over the World Wide Web is Secure HTTP (S-HTTP). Whereas SSL creates a secure connection between a client and a server, over which any amount of data can be sent securely, S-HTTP is designed to transmit individual messages securely. SSL and S-HTTP, therefore, can be seen as complementary rather than competing technologies. Both protocols have been approved by the Internet Engineering Task Force (IETF) as a standard.
