What is a SSL certificate?
SSL (Secure Sockets Layer) is a cryptographic protocol designed to keep communication safe over the internet.
Any computer in between you and the server can see your credit card numbers, usernames and passwords and other sensitive information if it is not encrypted with an SSL certificate. When an SSL certificate is used, the information becomes unreadable to everyone except for the server you are sending the information to.
