Os certificados curinga protegem todos os subdomínios no nível especificado quando você envia sua solicitação :
A Wildcard SSL certificate secures your website URL, and an unlimited number of its subdomains. A single Wildcard certificate can secure both www.coolexample.com, and blog.coolexample.com.
Wildcard certificates secure all of the subdomains at the level you specify when you submit your request. Just add an asterisk (*) in the subdomain area of the common name where you want to specify the wildcard. For example:
If you configure *.coolexample.com, you can secure
www.coolexample.com
photos.coolexample.com
blog.coolexample.com, etc.
If you configure *.www.coolexample.com, you can secure
mail.www.coolexample.com
photos.www.coolexample.com
blog.www.coolexample.com, etc.
