 The Secure Socket Layer, SSL for short, is a protocol by which many services that communicate over the Internet can do so in a secure fashion. Before we discuss how SSL works and what kinds of security it provides, let us first see what happens without SSL.
Life on the Internet without SSL
Let us make an analogy between communications between computers on the Internet and communications between people over the telephone. Without SSL, your computer-to-computer communications suffer from the same security problems from which your telephone communications suffer:

SSL versus TLS
TLS (Transport Layer Security) and SSL (Secure Sockets Layer) are protocols that provide data encryption and authentication between applications in scenarios where that data is being sent across an insecure network, such as checking your email (How does the Secure Socket Layer work?). The terms SSL and TLS are often used interchangeably or in conjunction with each other (TLS/SSL), but one is in fact the predecessor of the other — SSL 3.0 served as the basis for TLS 1.0 which, as a result, is sometimes referred to as SSL 3.1. With this said though, is there actually a difference between the two?
