Will a wildcard certificate work with a domain and a subdomain?



Can I setup a wildcard certificate to be used by these two? In the tutorials I have followed, they always use two or more subdomains without the main domain (tutorials here and here)

Simple answer is yes.

If you configure *.helpme.com, you can secure

  • www.helpme.com
  • photos.helpme.com
  • blog.helpme.com etc

The wildcard certificate will only secures the level of subdomain you specify. So for example, if a certificate is configured for *.www.helpme.com, it will not secure www.helpme.com.

This is why a typical wildcard certificate issued to example.com would include two names, *.example.com and example.com. –  David Schwartz Apr 19 '12 at 9:24
