Shared SSL is a means of securing access to a site with SSL (Secure Sockets Layer) for site owners without having them purchase their own SSL certificate. Web sites that employ shared SSL are, in fact, using the certificate shared by another domain. The domain that shares its SSL certificate with others is called Master SSL Domain.
You can pick any domain that belongs to you, switch on SSL support in Web hosting account settings, install a valid SSL certificate on that domain, and make it act as a Master SSL domain for all other domains hosted on the server. Or you can pick a domain that belongs to one of your users (reseller or client account), switch on SSL support in Web hosting account settings, install a valid SSL certificate on that domain, and make it act as a Master SSL domain for all domains of this user.
Once the Master SSL domain is assigned, you or your customers need to add shared SSL links for each domain that needs secure access.
