通配符子域的SSL

Question

I am trying to setup wildcard sub-domain. So my domain is www.mydomain.com so anything comes like this test.mydomain.com, welcome.mydomain.com will work, that is fine.

When it comes to SSL, if I am buying SSL for www.mydomain.com then will that same SSL certificate works for test.mydomain.com, welcome.mydomain.com? Since they are not real sub-domains just virtual.

If not do I need to buy wildcard SSL?

If I think technically all the wildcard sub-domains will point to same root folder and IP. From there using my code I will deliver different content. In that case my SSL certificate for www.mydomain.com will also work for test.mydomain.com right? I am not sure.

Any Guess?

Answer 1

NAME in the SSL certificate must exactly match domain name of the site. You need wildcard certificate. Non-wildcard will produce a wrong-site warning.
