An example of the verification of the domains included in the certificate.
Notice:
According to global standards, Certum does not issue SSL certificates for domains that are on the TLD (Top-Level Domain) list
You can check the TLD list under the link
Premium EV, Trusted SSL, SSL Commercial SSL:
an example of the verification of the domain included in the certificate.
| Example | |
|---|---|
|
In the CN field (Common Name) in the certificate in the first position there is the domain: your-domain.pl. In this example only one domain is verified: your-domain.pl. Attention: In the case of issuing a certificate for the domain www.your-domain.pl – the certificate automatically generates an alternative name for the domain (name of the host) without www e.g.: your-domain.pl. |
The Wildcard SSL certificate option
an example of the verification of a domain included in the certificate.
| Example | |
|---|---|
|
*.your-domain.pl The Wildcard SSL option is designed to protect subdomains within a single-level main domain (name of the host) as defined by the customer. An example of the usage of the Wildcard certificate option
|
In the CN field (Common Name) in the certificate in the first position there is the domain *.your-domain.pl. In this example only one domain is verified *.your-domain.pl. Attention:The Wildcard certificate option automatically creates the alternative domain name (name of the host):
Additionally the Wildcard certificate option does not automatically add www to the name of the domain (name of the host). |
The MultiDomain certificate option:
an example of the verification of the domains included in the certificate.
| Example | |
|---|---|
|
A single domain
|
In the CN field (Common Name) in the certificate in the first position there is the domain:your-domain.pl. The remaining names will be included in the ASN field (Alternative Subject Name). In this case the verification is done only for the first domain: your-domain.pl. The subdomains included in the main domain do not require additional verification. Attention: The MultiDomain option of the certificate does not automatically add www to the name of the domain (name of the host). |
| Example | |
|---|---|
|
Multiple domains
|
In the CN field (Common Name) in the certificate in the first position there is the domain:your-domain.pl. The remaining names will be included in the ASN field (Alternative Subject Name). In this example two domains are verified: your-domain.pl and your-second-domain.pl.The subdomains included in the main domain do not require additional verification. Attention: The MultiDomain option of the certificate does not automatically add www to the name of the domain (name of the host). |
