An SSL certificate has become one of the most crucial things needed on a website. Without it, your website will be marked as insecure. Some browsers like Google Chrome might even prevent users from accessing sites that do not have a valid SSL certificate. Also, I would highly suggest you read this article to better understand SSL certificates.
Getting an SSL Certificate
SSL certificates used to cost and still do. But you can actually get them for free via various organizations. One such organization is LetsEncrypt. LetsEncrypt provides free SSL certificates that are recognized by all browsers. These certificates are totally free of charge but the installation is a little complicated for people who are new to this. Anyways, We have another website called sslforfree. This website provides an easy interface to get an SSL certificate from LetsEncrypt.
It is pretty simple, you enter your website name and then you are told to verify the ownership of the domain and you get your ssl certificate. But what if your site needs an SSL certificate for a sub-domain? This is where Wildcard Certificates show up.
Wildcard SSL certificates
Wildcard SSL certificates are used when one might need SSL for sub-domains on a website. An SSL certificate is only issued at a time to one sub-domain by default. This means that you would need individual certificates for www.sitename.com, blog.sitename.com, admin.sitename.com and so on. This would end up in too many certificates and that isn’t very feasible. To solve this, we use wildcards. You already know about wildcards. Wildcards are used to house a value that can be anything. It is like a variable.
Getting a Wildcard SSL certificate
Getting a wildcard SSL certificate is extremely simple. Just open up sslforfree’s website. And in the website name form, type in xyz.com *.xyz.com where xyz.com is the domain name for your site. Just a single space between the two, no other punctuation.
