What is a Wild-card SSL certificate and how do they work?

When you register a standard SSL certificate it is only registered for one “fully qualified” domain (plus the root domain.com), so registration for “www.domain.com” will only work for “www.domain.com” and "domain.com", it won’t work for  “secure.domain.com”, so if you need an SSL to work on secure.domain.com and www.domain.com you normally need to buy two separate SSLs.

A wildcard SSL certificate works slightly differently and allows you to use the same SSL certificate to secure multiple sub-domains of a domain e.g. www.domain.com or secure.domain.com or mail.domain.com as well as just domain.com and they can be spread over different servers, if you need to secure a lot of sub-domains then this can be a cost-effective option.

When ordering a wildcard SSL you would enter the domain as *.yourdomain.com this would secure all sub-domains of yourdomain.com e.g. mail.yourdomain.com or ftp.yourdomain.com etc.
