Purpose of an SSL Certificate

An SSL (Secure Socket Layer) Certificate encrypts data sent between a web page and its visitors. Without an SSL certiciate, all communications with a website are sent over plain text.

What does this really mean? It means that when you submit a form containing personal information, usernames and passwords, or credit card information and the page containing the form is not behind an SSL ceritiface, the contents of the form are visible to anyone who has access networks involved in the request. This includes anyone on your home network (if you're conecting from home), anyone at your work network (if you're connecting from work), employees of your internet provider, or emploees at the facility where the website is hosted. All of these various networks are succeptable to hackers who can listen in on form submissions and collect your personal data.

SSL Certificates encrypt the data sent to and from the web page so that others cannot access the data. If someone were to listen in on the data transmissions, the encrpted data wound not be usable by hackers.
