For a browser to accept a cert while connecting to "wiki.xyz.com", the cert needs to be for "wiki.xyz.com" or for ".xyz.com". Note that ".*.xyz.com" is invalid.

For a browser to accept a cert while connecting to "wiki.xyz.com", the cert needs to be for "wiki.xyz.com" or for ".xyz.com". Note that ".*.xyz.com" is invalid. So called "wildcard certs" are usually more expensive than single and multi-domain certs.
