A Wildcard SSL Certificate is the best choice for you. Wildcard certificates secure domain names along with all subdomains. For example, a Wildcard certificate issued for *.mydomain.com may be used to secure all the following host names:
mydomain.com
www.mydomain.com
login.mydomain.com
secure.mydomain.com
support.mydomain.com etc.
