8Let the Certificate Administrator user define an export passphrase.

This step is only necessary if you want to fully separate the Certificate Administrator user role from the Administrator user role. If the admin user is removed from the certadmin group (as in <z_blue>Step 9), a Certificate Administrator export passphrase (caphrase) must be defined.

As long as the admin user is a member of the certadmin group (the default configuration), the admin user is prompted for an export passphrase each time a configuration backup that contains private keys is sent to a TFTP/FTP/SCP/SFTP server (command: /cfg/ptcfg). When the admin user is not a member of the certadmin group, the export passphrase defined by the Certificate Administrator is used instead to encrypt private keys in the configuration backup. The encryption of private keys using the export passphrase defined by the Certificate Administrator is performed transparently to the user, without prompting. When the configuration backup is restored, the Certificate Administrator must enter the correct export passphrase.

Note: If the export passphrase defined by the Certificate Administrator is lost, configuration backups made by the admin user while he or she was not a member of the certadmin group cannot be restored.

The export passphrase defined by the Certificate Administrator remains the same until changed by using the /cfg/sys/user/caphrase command. For users who are not members of the certadmin group, the caphrase command in the User menu is hidden. Only users who are members of the certadmin group should know the export passphrase. The export passphrase can contain spaces and is case sensitive.

Re-enter to confirm: Passphrase changed.
