What is my Common Name? | SSL Certificates - Create (2024)
As part of generating an SSL certificate you will be asked for the common name. The common name is the domain name you wish to secure with your certificate.
If you are creating a single domain certificate, entering the common name is straightforward: it is the single domain you wish to secure. Don’t forget to include the subdomain if your single address includes a subdomain.
Note
When you have a single-address certificate, if you create the CSR with the bare domain, such as “www.example.com”, the “www” subdomain is added automatically by the certificate authority. For example, “example.com” will secure both “example.com” and “www.example.com”. The reverse is also true; if you create the CSR with the “www” subdomain, the bare domain will be also secure. Just make sure to include a file for both if you validate by file.
If you are creating a certificate for several addresses you only need to include the primary domain you wish to secure. This is the only domain you will not be able to change. You will be able to add or modify other domains on your certificate in your Gandi interface after the completion of your order.
Unlike single address certificates, several address certificates do not also secure the “www” subdomain of a bare address you specify. You must declare each domain or subdomain you want to cover. In other words, if you have a several address certificate and secure the bare domains, they will not also secure the corresponding “www” subdomains.
If you are creating a full domain certificate, you must put in a “*” for the location of the subdomains you want to secure. For example, *.example.com will secure any subdomain that occurs right before the bare domain, such as blog.example.com, but will not include any subsequent subdomains, such as blog.store.example.com.
Note
Full domain certificates also secure the raw domain in addition to any subdomains.
The common name is the domain name you wish to secure with your certificate. If you are creating a single domain certificate
domain certificate
A domain validated certificate (DV) is an X.509 public key certificate typically used for Transport Layer Security (TLS) where the domain name of the applicant is validated by proving some control over a DNS domain.

, entering the common name is straightforward: it is the single domain you wish to secure. Don't forget to include the subdomain if your single address includes a subdomain.
The common name is the hostname for which an SSL certificate is issued. This can vary between types of certificate. Most commonly, the common name is the entire hostname, such as 'www.yourdomainname.com'. In the case of a wildcard, however, the common name is '*.
The Common Name (AKA CN) represents the server name protected by the SSL certificate. The certificate is valid only if the request hostname matches the certificate common name. Most web browsers display a warning message when connecting to an address that does not match the common name in the certificate.
If you purchased a dedicated IP address and an SSL certificate was installed immediately afterward, the domain can still be associated with the previous IP address. To solve the problem, just wait a while. As soon as the DNS records are updated, the error will disappear.
I was wondering if can I find out the common name (CN) from the certificate using the Linux or Unix command line option? Yes, you find and extract the common name (CN) from the certificate using openssl command itself.
Names that are the same for groups like animals, places, or people are called common names. Eg., girl, boy, peaco*ck, chair, dog etc. Names that are unique to a particular person, place, thing, or animal are called special or unique names. Eg., Sandy, Lisa, Mumbai, Hyderabad, etc.
A common name is not the organism's scientific name. Common names are used by people to describe something. Some common names are not always used by some people. A common name are also known as a vernacular name, English name, colloquial name, trivial name, trivial epithet, country name, popular name, or farmer's name.
A certificate can be used to represent a user's digital identity. In most cases, a user certificate is mapped back to a user account. Access control will then be based on this user account. One of the most common implementations of user certificates is via smart cards.
While generating a CSR, you will be required to enter information in the Common Name field. Certificates are specific to the Common Name that they have been issued to at the Host level. The Common Name must be the same as the Web address you access when connecting to a secure site.
Common Name Mismatch Error is a widespread error that occurs when the Common Name or SAN value of your SSL / TLS certificate does not correspond to the domain name. The error message may have different content depending on the browser used.
To change the common name after the certificate has been issued you must generate a new Certificate Signing Request (CSR) specifying the correct common name. For this to be done you will require to purchase a new certificate.
The real cause of the error is simple: the name of the site you're visiting isn't included on the certificate. For example, if you visited get.example.com and the certificate only contained example.com and www.example.com , you'd see this error.
To check your certificate for a name error, we recommend that you use our SSL Certificate Checker. Enter your domain in the server address box; if the certificate name doesn't match, you will get an error message stating "Certificate does not match name example.com".
The common name is the domain name you wish to secure with your certificate. If you are creating a single domain certificate, entering the common name is straightforward: it is the single domain you wish to secure. Don't forget to include the subdomain if your single address includes a subdomain.
The more accepted form is to put the preferred name in brackets, e.g. Andrew (Andy) McSomeone. It's an official document, so your official name should be the main one, especially if it has to match your passport, etc. “Andrew (Andy) McSomeone” effectively says: Yes, I'm Andrew McSomeone, but please call me Andy.
