What is a Wildcard SSL/TLS certificate? Print

Wildcard SSL/TLS allows the use of an unlimited number of subdomains in the SSL/TLS certificate. Any full domain that matches *.yourdomain.com (where * can be any word and yourdomain.com is your domain) will be secured by a wildcard SSL digital certificate. For instance, yourdomain.com, www.yourdomain.com, mail.yourdomain.com, and any other combination of yourdomain.com would be secured by a wildcard certificate issued to *.yourdomain.com.
