What is the difference between an SSL certificate and a Wildcard SSL certificate?

Last Updated: March 21, 2006 11:59 AM

An SSL certificate secures a single domain name.

A Wildcard SSL certificate secures multiple sub-domains of a single domain name.

When generating a Certificate Signing Request (CSR) for a Wildcard certificate, please add an asterisk (*) on the left side of the Common Name (e.g., "*" or "www*"). This secures all sub-domains of the domain defined as the Common Name.

NOTE: An SSL certificate only secures the exact fully qualified domain entered as the Common Name in your certificate signing request. Thus, if your certificate secures "," it will not secure the domain "" If you need to secure both domains, you must request an SSL certificate for each of them.
