The code example below outputs the certificate request in Base64 format to the command-line console. You must send the certificate request to a certification authority (CA) within the organization, a trusted CA outside the organization, or a commercial CA. You can do this by pasting the certificate request output into an e-mail message or into the appropriate field on the certificate request Web page of the CA. You can also save the certificate request to a file using a text editor such as Notepad.

The certificate that results has the following attributes associated with it:

  • Subject name: c=<ES>,o=<Woodgrove Bank>,cn=mail1.woodgrovebank.com
  • Subject alternate names: woodgrovebank.com and example.com
  • An exportable private key
