What type of certificate should one opt for?

If the proprietor of your website is an individual (i.e., without a business license), you are only eligible to apply for either a free Domain Validation (DV) certificate or a paid Domain Validation (DV) certificate.
For financial and payment enterprises, EV SSL certificates are recommended.
For general enterprises, OV SSL certificates and SSL certificates with a higher trust level are recommended.
For website URLs being called as a mobile websites or interface, OV SSL certificates and SSL certificates with a higher trust level are recommended.

How should one select a certificate provider?

Choose an appropriate certificate provider based on each SSL certificate’s browser compatibility test report and your enterprise’s business requirements. For more information, see Browser Compatibility Test Report.

How do I choose a certificate based on the number of supported domain names?

Tencent Cloud provides the following four 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, sub-domains under the second-level domain are not supported. The domain name can go down to 100 levels at most.
Multi-domain SSL certificate: 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: Supports binding to one and only one wildcard domain, which allows the addition of a single wildcard. For instance, *.tencent.com, *.example.tencent.com are supported up to 100 levels. Multiple wildcard domains like ..tencent.com are not supported.
Multi-domain wildcard SSL certificate: Supports binding multiple wildcard domain names, each of which can only include one wildcard, such as *.tencent.com and *.example.tencent.com (up to 100 levels). Multi-wildcard domain names like ..tencent.com are not supported.
