Add free ssl certificate to subdomain in cloudflare
A Wildcard SSL Certificate is a type of SSL that uses a single certificate to encrypt your domain and multiple subdomains. The certificate’s subdomains must all have the same primary domain.
Because they all use the same primary domain, example.com, www.example.com, blog.example.com, store.example.com, and billing.example.com could all be secured with the same wildcard SSL. However, since billing.yoursitesdomain.com uses a different primary domain, it could not be used with this certificate.
Each time you want an additional subdomain to load safely with https, our administrators must manually add the virtual host entries for the subdomain. This is true even for newly created subdomains via cPanel. A re-issue request via phone or Live Chat will be required any time you want a new subdomain to load securely with the Wildcard SSL.

We intend to use an SSL certificate on our web server, which hosts a number of different web applications. Those web applications are hosted on the same web server as www.example.com/sub1, /sub2, and so on, but they are unrelated. Do we still need SSL certificates for each and every web application if we already have an SSL certificate for the main domain?
Subject Alternative Name (SAN) certificates are available that cover different domains or subdomains in a single certificate. All domains and subdomains are noted on the certificate when it is issued. You’ll need to get the certificate re-issued if you want to add or delete subdomains.

With a wildcard SSL certificate, you can secure an infinite number of subdomains. It’s an excellent choice for anyone who hosts or maintains different sites or pages under the same domain. The certificate’s one-time fee covers any extra subdomains you may add in the future.
A Wildcard SSL Certificate is issued to *.yourdomain.com, where the asterisk denotes all possible subdomains, as opposed to a standard SSL Certificate, which is issued to a single Fully Qualified Domain Name (e.g., www.yourdomain.com), which means it can only be used to secure the exact domain to which it was issued. For Domain Validated (DV) and Organization Validated (OV) certificates, wildcards are an alternative.
Please make sure to order your certificate in the correct currency and from the region where the company in the certificate is based. If your certificate request does not meet these requirements when you place your order, your order may be delayed or not processed.
It’s simple: we create a Certificate with the “Common Name” *.yourdomain.com and the “Subject Alternative Name (SAN)” yourdomain.com. The * (wildcard) enables the Certificate to be used on any subdomain of the yourdomain.com domain name, and the SAN ensures that SSL works even though no subdomain is specified.

I’m going to set up a websocket server at ws.mysite.example. I like both the web socket server and domain.example to be SSL encrypted. Is it necessary to buy a new certificate for each subdomain I set up? Is it necessary for each subdomain I build to have its own IP address? I’ll most likely have multiple subdomains.
Yes and no, depending on the situation. A single domain SSL certificate, such as www.domain.example, will be normative. Aside from the standard single domain certificate, you can also get wildcard and multidomain certificates.
They are usually more expensive than regular certificates, and since you share a single certificate, they are not the most secure option unless you host an anything.mydomain.example type of application, in which case they are the only viable alternative.
If your web server supports SNI, you won’t need different IP addresses. SNI, on the other hand, is only supported in modern browsers (IE6 and below are not supported). SNI is transparently supported by recent versions of Nginx and Apache (just add SSL enabled virtual hosts).
