What is a Wildcard SSL?

The Wildcard SSL is a digital certificate that allows businesses to secure a primary domain and unlimited first-level sub-domains. For example, if your website has several sub-domains, it would not be easy to manage several different SSL certificates. It is where the Wildcard SSL certificate is helpful. You can remove the hassles of having to secure the sub-domains with separate certificates. 

Several businesses utilize the sub-domains for various other functions. Some of them can be client-facing too. The Wildcard SSL certificate helps to secure all these sub-domains together in one place. The certificate has a wildcard character in the field to include the domain name. It helps the certificate to secure several first-level sub-domains under the chosen primary domain.

The certificate uses the Public Key Infrastructure (PKI), and all the first-level sub-domains are protected. When using the Wildcard, in the field for the domain, you must use an asterisk (*) to show where the sub-domain would be. 

For example, the certificate that has been issued for * will also support,,,,, etc.

Once the certificate is installed, the communication taking place between the visitor’s browser and the webserver will be encrypted. They are available only in Domain Validation and Organisation Validation levels only.  You can install a cheap Wildcard SSL from CheapSSLShop to ensure the security of all the first-level sub-domains.

The server would have a private key that can unlock the message. The second-level sub-domains cannot be covered within the same certificate. You must have another Wildcard SSL certificate for the second-level sub-domains or buy a multi-domain wildcard SSL cert. The private key is shared across all the sub-domains.
