SSL (Secure Socket Layer) is a technology that establishes an encrypted connection, between a web server and a browser. Its primary function is to ensure that any data transmitted between these two entities remains safe and cannot be intercepted by individuals. To achieve this an SSL certificate is used, which serves as a validation of a website identity and enables communication.
A ssl wildcard as the name implies is a type of SSL certificate designed to provide security for subdomains under one main domain. This offers convenience and enhanced protection for website owners who have subdomains or anticipate creating more in the future.
Traditionally if you wished to secure subdomains with SSL you would have to purchase SSL certificates for each subdomain. However, this can become both expensive and time-consuming particularly if there are subdomains involved. The advantage of utilizing a Wildcard SSL certificate lies in its ability to secure a domain along, with all its associated subdomains using one comprehensive certificate.
For instance, if your website has subdomains, like blog.example.com, shop.example.com, and mail.example.com a Wildcard SSL certificate can secure all these subdomains with a certificate.
So how exactly does a Wildcard SSL certificate function?
When you acquire a Wildcard SSL certificate you specify the domain you want to protect such as example.com. The certificate is then issued with an asterisk (*) as the leftmost part of the domain name like *.example.com. This asterisk acts as a wildcard. Permits the certificate to be used for any subdomain under the domain.
There are benefits to using a Wildcard SSL certificate. Firstly, it simplifies the management of SSL certificates. Of keeping track of certificates for each subdomain individually you only need to manage one certificate that covers all subdomains. This can save time and effort for organizations with numerous subdomains.
Secondly from a cost perspective opting for a Wildcard SSL certificate can be more economical, than purchasing certificates for each subdomain.
The price of a Wildcard SSL certificate is usually slightly higher than an SSL certificate. It is much cheaper compared to purchasing multiple separate certificates.
Additionally, having a Wildcard SSL certificate ensures a user experience. When visitors access your website or any of its subdomains they won’t encounter security warnings. Need to trust multiple certificates. With a Wildcard SSL certificate, all subdomains are protected under one trusted certificate providing security and trust for your website visitors.
It’s important to keep in mind that while Wildcard SSL certificates offer benefits they do have some limitations. These certificates only secure subdomains at the level of the domain you bought the certificate for. For instance, a Wildcard SSL certificate, for *.example.com will secure blog.example.com and shop.example.com. Won’t secure mail.blog.example.com.
If you have subdomains at levels you might have to buy Wildcard SSL certificates or opt for a different kind of certificate called Multi Domain SSL certificate.
Conclusion
In summary, selecting a Wildcard SSL certificate is an option, for website owners who have subdomains. It provides convenience and cost-effectiveness. Ensures a user experience. By securing all subdomains under a certificate you can save time, energy, and money while guaranteeing the security and credibility of your website.
