SSL Introduction

Secure Sockets Layer (SSL) :

The Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message transmission on the Internet. SSL has recently been succeeded by Transport Layer Security (TLS), which is based on SSL. SSL uses a program layer located between the Internet's Hypertext Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of both the Microsoft and Netscape browsers and most Web server products. Developed by Netscape, SSL also gained the support of Microsoft and other Internet client/server developers as well and became the de facto standard until evolving into Transport Layer Security. The "sockets" part of the term refers to the sockets method of passing data back and forth between a client and a server program in a network or between program layers in the same computer. SSL uses the public-and-private key encryption system from RSA, which also includes the use of a digital certificate.

This type of secure connection ensures that all data exchanged between clients and servers is encrypted, and is therefore not readable by a third party on the Internet. SSL has gained popularity in the Internet industry primarily because of its use of public-key certificates as a means of authenticating principles.


In a virtual world, there is always an element of doubt when sending or receiving sensitive information. A large percentage of internet users leave websites when asked to provide any information about themselves, simply because the website was not a secure website. There is no better way of building user's trust than by enabling SSL on your website and getting an SSL Certificate for your website.
