An SSL certificate is a bit of code on your web server that provides security for online communications. When a web browser contacts your secured website, the SSL certificate enables an encrypted connection. It’s kind of like sealing a letter in an envelope before sending it through the mail.
SSL certificates also inspire trust because each SSL certificate contains identification information. When you request an SSL certificate, a third party (such as RapidTemok, Thawte, Comodo, GeoTrust, Symantec etc.) verifies your organization’s information and issues a unique certificate to you with that information. This is known as the authentication process.
