Wildcard SSL

The biggest difference between the wildcard SSL certificate and the ordinary SSL certificate is that the wildcard certificate can protect the main domain name and an unlimited number of subdomains, which means that users can protect any number of subdomains by applying for a single wildcard SSL certificate. For example, suppose a user applies for a wildcard certificate for * .example.com, then this certificate can protect www.example.com, bolg.example.com, and other sites at the same time, and there is no need to apply for an additional SSL certificate for another related site.

The emergence of wildcard certificates can not only help users save extra money to apply for SSL certificates, but also help users to save a lot of time in applying for certificates. From this, we can see that if a user has more than one sub-domain name platform at the same time, he can try to apply for a wildcard certificate so that these sub-domain name websites can be protected at the same time.

Although wildcard certificates are quite friendly for platforms with multiple sub-domain names, there are also inconveniences. First of all, at present, only DV (domain name type) SSL certificate and OV (enterprise type) SSL certificate support the function of wildcard certificate, while users of EV (enhanced) SSL certificate can not enjoy the function of wildcard SSL certificate. On the other hand, wildcard certificates do not support multiple domain names. During the management of SSL certificates, users can add wildcard SSL domain names as multiple domains, but cannot add multiple domains as wildcard SSL domains.

Although these shortcomings of the wildcard SSL certificate cannot be eliminated, the emergence of the wildcard SSL certificate also greatly facilitates users who have multiple sub-domain names at the same time. At the same time, the wildcard certificate can protect multiple subdomains, which makes it highly compatible with 99% of browsers.

At this point, the study of "what is the wildcard SSL" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
