Let's start by defining SSL. SSL is an encryption technology developed by Netscape.
It is used to create an encrypted connection between a web server and the web browser in which you will view web pages. By using SSL, you can securely view the information sent to your browser, knowing that nobody else can access it.
SSL works by means of an SSL certificate that is installed on a server and is used to identify you. So the question is, how do you know whether you are using a secure connection to connect to the server? If you have a secure connection, you will see a padlock icon in your browser or the address bar will be colored green.
To ensure you have a secure connection, you can also access the site using https:// in your browser rather than the usual http://.
SSL certificates are provided by Certificate Authorities (CAs).
