SSL stands for Secure Sockets Layer and it is a protocol developed by Netscape to handle and keep private the sensitive information required by e-commerce sites. Data such as credit card numbers and other personal customer data falls into this category. You always know when you are browsing on an SSL encoded web page because it’s URL will begin with “https” instead of “http.” The protocol uses a series of techniques to maintain security such as session cookies and data encryption. Most e-commerce sites employ SSL for their payment input and processing web pages to give the customer an added level of security.
SSL has been built upon since it’s creation and there are now systems called TSL or Transport Layer Security that add extra security for uses such as voice over IP and forward secrecy. When a client browser connects to an SSL enabled web page, there are about 10 steps that take place before the page is even displayed. When the client shows the “https” URL in the address bar, the security features are already operating and in place.
Using SSL protocol on a webpage is another way to let a client know that their transaction on your website is secure and private.
