What is Wildcard Certificate
A wildcard SSL certificate is a single SSL/TLS certificate that provides you with time and cost savings for your small businesses. This certificate usually includes a wildcard character that is (*) which is used in the domain name field. It can also secure multiple subdomains of the primary domain.
With the addition of SANs in this, one can easily purchase any Wildcard SSL certificate, making it so simple to control your sites and save money on a wide range of subdomains. This all includes;
Usually, the primary domain later includes the subdomains. It.example.com, Calendar.example.com, Portal.example.com, and list.example.com are all Subject Alternative (SANs) examples for the same primary domain.
Working On The Wildcard Certificate
We primarily look for multiple certificates to secure the internet traffic of our website/business, but you don’t have to buy multiple certificates if you have a wildcard SSL certificate. The Wildcard certificate covers all subdomain names. For example, a Single wildcard certificate for google can be used to secure google as www.google.com and “calendar.google.com.”
Two Main Categories For Wildcard Certificates
Wildcard certificate falls under two main categories;
Domain-Validate (DV) Certificates
These can be delivered very fast and quickly, followed by the purchase. Make sure that you have proof that you own the domain.
Organization-Validated (OV) Certificates
These certificates are high quality and can only be used by registered businesses, as the company information will be placed in the certificate. Make sure that you go through the review process for approval.
The wildcard SSL certificate houses a private key; this key is developed when the certificate signing request (CSR) process is made while creating the certificate. This key is shared across all the domains and subdomains. If you or your business uses multiple servers, you’ll be required to copy the private key onto each server when you install the certificate.
The Procedure Of Incorporating SAN
You can add 250 SANs to your certificate for free as an optional feature when you purchase Wildcard SSL/TLS.
WARNING: Before installing a wildcard certificate, consult your software’s documentation to ensure that the server in question can handle it.
Wildcard Certificates Compatibility
Is a wildcard certificate compatible with every server and browser? The answer is that most of the servers support Wildcard SSL certificates. You will need to consult your service provider if you need more clarification into it.
Benefits and Advantages of a Wildcard SSL Certificate
A wildcard SSL certificate will save you a whole lot of cash. When you have multiple subdomains that need to be secured, buying individual his SSL certificates for each subdomain can be high-priced. not only that, but you also ought to keep in mind the server cost of each individual IP address for each SSL certificates and domain name pair. You can reduce these charges by purchasing a wildcard certificate that covers all your subdomains.
SSL certificate management should also be considered. If all subdomains are on his one computer at installation time, he only needs to install the wildcard SSL certificate once. If I bought a separate SSL certificate for each subdomain, I would have to install each SSL certificate on the server, which would take longer than necessary. When you need to renew your SSL certificate, you can save time by only renewing a single wildcard SSL certificate.
