When creating a single domain certificate, the common name is self-explanatory: it’s the single domain you want to protect. If your single address contains a subdomain, don’t forget to include it.
If you have a single-address certificate and create the CSR with the bare domain, such as “www.example.com,” the certificate authority will automatically add the “www” subdomain. For example, the domain name “example.com” would protect both “example.com” and “www.example.com.” The opposite is also true: if you create a CSR with the “www” subdomain, the bare domain will be secure as well.
Multi-domain certificates, unlike single-address certificates, do not secure the “www” subdomain of a bare address you specify. Each domain or subdomain you want to cover must be declared. In other words, if you have a multi-domain certificate and secure the bare domains, the corresponding “www” subdomains will not be secured.
You must include a “*” for the location of the subdomains you want to secure when creating a wildcard certificate. For example, *.example.com will secure any subdomain that comes before the bare domain, such as blog.example.com, but not any subdomains after that, such as blog.store.example.com.

For a registered base-domain, wildcard SSL certificates will allow you to secure an unlimited number of subdomains. Let’s pretend you own the domain example.com. Any-subdomain.example.com can be secured with a wildcard certificate for *.example.com. The wildcard (*), also known as a star, may be any valid subdomain.
A Common Name, or CN for short, is assigned to each SSL certificate. The CN will cause some head scratching and Googling when creating a Certificate Signing Request (CSR). Even the most seasoned techies can be confused by the meaning of Common Name, particularly when it comes to the CN for a wildcard certificate.
The fully qualified domain name (FQDN) that you want to secure with an SSL certificate is simply the CN. The CN would be shopping.example.com if you just wanted to secure a single non-wildcard FQDN like https://shopping.example.com.
Wildcard SSL certificates can help you save money on both certificate and certificate management. Instead of buying, managing, and renewing multiple certificates with the same base-domain, you only need to deal with one wildcard certificate.

The reason for this is to avoid a homograph attack, which takes advantage of characters that are different but appear to be the same.

Create self signed certificates with subject alternative names

The phishing and other malicious uses of the lookalike characters are possible. For example, the English letter “a” appears to be identical to the Cyrillic “a,” but they are encoded as two distinct letters by computers. This enables the registration of domains that appear to be valid.
Some companies that have their own internal or private PKI have been issuing certificates that only have the Common Name field. Many people are unaware that the “Common Name” field of an SSL certificate, which contains the domain name for which the certificate is valid, was phased out almost two decades ago via RFC (RFC 2818 was published in 2000). Instead, the SAN (Subject Alternative Name) field is the appropriate place to list the domain(s). Since 2012, all publicly trusted certificate authorities have been required to have a SAN (Subject Alternative Name).

The server name protected by the SSL certificate is represented by the Common Name (AKA CN). Only if the request hostname matches the certificate common name is the certificate valid. When connecting to an address that does not match the common name in the certificate, most web browsers display a warning message.
The common name of a single-name certificate is a single host name (e.g. example.com, www.example.com) or a wildcard name (e.g. *.example.com) in the case of a wildcard certificate.
The common name isn’t a web address. There is no protocol (e.g., http:// or https://), port number, or pathname included. The URLs https://example.com and example.com/path, for example, are wrong. The common name in both cases should be example.com.
It must be identical to the name of the server on which the certificate is installed. If the certificate is for a subdomain, the entire subdomain should be used. For example, the common name for example.com’s www and api subdomains would be www.example.com or api.example.com, not example.com.
