SSL is a security technology that protects sensitive information from being seen while the information travelling from the web server and the browser. Normally without a SSL Certificate the information transmitted can be seen by a third party. For example imagine sending a clear envelope to the post office and everyone can see the information that you have in the clear envelope. If it looks valuable they can steal the information or alter it. The SSL creates a layer and scrambles the words which in return protects the information sent. This is called encryption which protects your information from being seen by unwanted users.
Each Certificate contains a private key and a public key. The public key scrambles the information. The private key unscrambles the code. When the browser points to a secured website there is a SSL transaction that will verify the authentication of the website, and the client.
Authentication also plays a major role with SSL encryption.
Each SSL is created for a specific domain for a verified business. When the transaction occurs it's like a handshake taking place in person. The SSL Certificate is verified. Authentication matters as if you were issued a Drivers license, birth certificate or a passport. Imagine getting a letter in the mail the letter is requesting that you enter your bank account information as well as other private information. You notice that envelope is missing a return address or any information regarding whose requesting the information. This is why authentication is important certificates are created for a particular server where the domain for a verified business entity.
