TYPES OF SSL CERTIFICATES

Single Domain SSL Certificates

A single-domain SSL certificate applies to one domain and one domain only. It can not be used to authenticate any other domain, not indeed subdomains of the domain it's issued for.

All runners on this domain are also secured with the certificate; for case, ifcloudflare.com has a single-domain certificate, alsocloudflare.com/learning (the Learning Center main runner) is also covered by that instrument.

Wildcard SSL Certificates

Wildcard SSL certificates are for a single domain and all its subdomains. A subdomain is under the marquee of the main domain. Generally, subdomains will have an address that begins with a commodity other than www.'

For illustration,www.cloudflare.com has several subdomains, includingblog.cloudflare.com,support.cloudflare.com, anddevelopers.cloudflare.com. Each is a subdomain under the maincloudflare.com domain.

A single Wildcard SSL certificate can apply to all of these subdomains. Any subdomain will be listed in the SSL certificate. Druggies can see a list of subdomains covered by a particular certificate by clicking on the padlock in the URL bar of their cybersurfer, also clicking on"Certificate" (in Chrome) to view the certificate's details.

Multi-Domain SSL Certificates (MDC)

A multi-domain SSL certificate, or MDC, lists multiple distinct domains on one certificate. With an MDC, domains that aren't subdomains of each other can partake in a certificate
