    1. Common name
    2. Country
    3. Locality
    4. Organization
    5. Organization Unit
    6. State
  14. On the certificate properties page, enter in the following info for the Alternative Name
    1. DNS of the FQDN (common name)
    2. DNS of the SAN name (short name)
  15. You should now have something like this
    certificate request - properties
  16. Optionally, click on the Private Key tab, expand Key options, and check Make private key exportable
    certificate request - private key exportable
  17. Click OK on the Certificate Properties window
  18. Click Enroll
    certificate enrollment - enroll
  19. Click Finish once the request has been signed

At this point, you can export the certificate from the machine or have your application reference it.
