SSL is an acronym for Secure Sockets Layer, an encryption technology that was created by Netscape. SSL creates an encrypted connection between your web server and your visitors’ web browser allowing for private information to be transmitted without the problems of eavesdropping, data tampering, or message forgery.
Using an SSL certificate creates an encrypted connection between the user’s web browser and the web server. This means that any data transmitted between the web server and the web browser can not be read without first being decrypted. This protects the data from being spied upon by someone else on the internet because they will not be able to understand the encrypted data.
