What Ssl certificate is needed so that several different domains work on one server on one virtualhost?

Question

Apache HTTP Server

I have a dedik, on it 1 vhost serves all sites. That is, depending on the domain name, the corresponding site is already issued.
That is, there is a default vhost - vhost a. No matter how you contact the server, you will still get to this vhost. Inside is a script that looks at the domain name that is being requested. For example , mydomain.com. It gives the visitor content that matches mydomain.com.
All this works fine on http.
How to tie ssl to all this? domains can be added and subtracted during the month.
That is, either several certificates for one server, or one for a bunch of domains.
Any ideas?

with it it is possible to add domains during the entire validity period of the certificate
