AFAIK this is impossible without some new (and not widely supported)
extensions to the SSL protocol. Please remember that the SSL negotiation
takes place before nginx can read the headers (which contain vhost
information). The extensions are described in RFC 4366.

You can specify several server blocks with the same listen ip:port
directive but it won't help you a bit with https, actually.

Nginx will use the certificate from the first server block configured to
listen on each IP address (well, maybe not the first, but only from a single
one, for reasons outlined above).

Your best bet would be to get a wildcard certificate for *
