    1. Common name: Fully-qualified domain name (FQDN) like unless you are generating a single-domain Wildcard SSL, in which case the common name should be formatted like *
    2. Organization: Your organization's legal name. If you do not have a company or organization, you can put another name or N/A here.
    3. Organizational unit: Your department within your organization. If you do not have an organization, put N/A.
