The certificate authority you created through this procedure is the one that signs the certificate the appliance sends to its clients in the starting phase of the SSL-secured communication. For information on other settings for the communication between the appliance and its clients, see SSL Client Context engine settings. Import a certificate authority This section describes a procedure for importing an existing certificate authority (CA) for use instead of the certificate authority that is implemented on the appliance after the initial setup.

To do this, click the Browse button and browse to a suitable file. The file must be encoded in PEM format. The key must have a length of at least 2048 bit. 6 [Conditional] If the private key is protected by a password, type it in the Password field.
