How do I choose a certificate provider?
Choose an appropriate certificate provider based on each SSL certificate’s browser compatibility test report and your enterprise’s business requirements.

Tencent Cloud provides the following 4 types of domain names:
Single-domain SSL certificate: only one domain name can be bound. This can be a second-level domain name like tencent.com, or a third-level domain name like example.tencent.com. However, binding all sub-domain names under a second-level domain name is not supported. Up to 100 levels of domain name are supported.
Multi-domain name: a single certificate can be bound to multiple domain names, subject to the maximum number of supported domain names stated on Tencent Cloud's official website.
Wildcard domain name: only 1 wildcard domain name with only 1 wildcard can be bound, such as *.tencent.com and *.example.tencent.com (up to 100 levels). A wildcard domain name with multiple wildcards like *.*.tencent.com is not supported.
Multi-wildcard domain name: multiple wildcard domain names with each containing only 1 wildcard can be bound, such as *.tencent.com and *.example.tencent.com (up to 100 levels). A wildcard domain name with multiple wildcards like *.*.tencent.com is not supported.
