Once prompted for a "Common Name" enter the Fully Qualified Domain Name (FQDN) that you wish to secure in the certificate

For Wildcard: If you are going to be requesting a Wildcard Certificate you will need to place an asterisk * in front of the domain (e.g. *.entrust.com)

You will also be prompted for the following information:

Attribute Prefix Description Example
Country/Region C Business Location - Country CA
State/Province ST Business Location - State/Province Ontario
City/Locality L Business Location - City Ottawa
Organization Unit OU Organization Unit if required to be listed* Optional*
Organization O Organization’s legal business name Entrust Datacard
Common Name CN Domain to be secured by certificate www.testcertificates.com

PLEASE NOTE: Do not use a Challenge Password

* If you require an Organization Unit, the value you place will be required to pass verification. If the OU is considered misleading or a registered trademark to a different legal entity it will be removed from certificate that is issued and show up with no value.
