What Is SSL?

SSL Stands for Secure Sockets Layer. This is a security protocol that provides communications security over a computer network by encryption. Several versions of this protocol are used to secure web browsing, email, Internet faxing, instant messaging, and voice-over-IP. Most of the websites use this protocol to securely obtain confidential user information, including credit card numbers. The URLs that require an SSL connection start with https: instead of http:.

How does it work?

When a browser or server attempts to connect to a Website or Web server secured with SSL, the browser/server requests that the web server identifies itself. Then, a copy of SSL certificate of the web server is sent to the browser or server.The browser or server receives the SSL certificate and checks to see whether or not it trusts the SSL certificate. If it does, it sends a confirmation message to the Web server. After receiving the confirmation message, the web server sends back a digitally signed acknowledgment certificate to the browser. And an SSL encrypted session is started. And after the session is started, all the data shared between the web server and the browser is encrypted.
