What is difference between Wildcard SSL and just normal SSL?


At a very high-level, a "Wildcard" SSL certificate would allow <any-subdomain>.example.com. Whereas a "normal" SSL cert would be limited to just a single host. eg. example.com or my-subdomain.example.com, but not both.

However, many "normal" SSL certs do cover both the apex and www subdomains these days. ie. example.com and www.example.com - since this is a very common requirement.

Or were you after a deeper explanation?

    Consider that a "normal" cert can act as a Wildcard for up to 500 tertiary subdomains by adding them into the SAN field of the certificate. – Dallas Jul 5 '17 at 4:00
