State or Province Name – This is the full name of the state your organization operates from. For example, this might be “California” or “Michigan”.
Locality Name – Name of the city your organization operates from. Examples might include “Lansing” or “Phoenix”. Don’t use abbreviations in this field. For example, “St. Helena” should be “Saint Helena”.
Organization Name – The name of your organization. If you are a business, use must use your legal name. If you are applying as an individual, you use your full name instead.
Organizational Unit Name – If applying as a business, you can enter your “Doing Business As” (DBA) name here. Alternately, you can use a department name here. For example, “IT Department” or “Web Administration”.
Common Name – The domain name that you are purchasing a SSL certificate for. This must be a fully qualified domain name (FQDN). An example might be mydomain.com.
Note:
If you are applying for a special wildcard SSL certificate, you will need to enter an asterisk for the subdomain. An example in that case might be *.mydomain.com. Never include the “http://”, “https://”, or any other special characters in this field. Never include text after the top level domain at the end. For example, your common name should end in .com, .net, (or whatever other extension you are applying for.)
Email Address – An email address that can be used as a point of contact for your domain. Be sure the address is valid!
A challenge password – An optional password to further secure your certificate. Be sure to remember this password if you choose to use it. It must be at least 4 characters long. You can skip this step if you like.
An optional company name – Another optional step. Fill in your company name if you wish. This is not required for web SSL certificates.
