These values form part of the distinguished name for the certificate authority.  Enter a descriptive name for the certificate authority in the Common Name text field. This value will be used to identify the intermediate certificate as the issuer of client and server certificates from this certificate authority.  Enter a contact email address in the Email Address text field. This email address will be included in the certificate authority's certificate, and provides a way for users of the certificate authority to contact your organization. In the Private Key section:  Mark the Generate a new private key check box to create a new private key for the intermediate certificate. This is only necessary if you are recreating the entire certificate authority from the beginning. Note: If you have previously created any client or server certificates or performed device provisioning using the existing intermediate CA certificate, these certificates will be invalidated when changing the intermediate CA's private key.
