Wildcard certificates enable the protection of any sub-domains associated with a primary domain. If you wish to secure existing or future sub-domains under example.org, simply create a wildcard certificate. To do this, prefix the domain with an asterisk and follow it with a period. Additionally, wildcard certificates provide security for the root domain, eliminating the need to input the root domain separately. For instance, to generate a wildcard certificate for example.org, you would enter *.example.org. Should you require certificates for various domains, like example.org and example.com, a distinct wildcard certificate must be generated for each domain, and domain verification will be necessary for every one. This convenient approach allows for streamlined management of your SSL needs across multiple domains.
