Modify key protection key (KPK)
To modify the key protection key, use the NetBackup Key Management Service (KMS) utility command (the nbkmsutil command) with the included arguments.
The KPK is used to encrypt the KMS keys. Currently, the KPK is per keystore. To modify the current KPK, the user should provide an optional seed or pass phrase. Also, provide an ID (KPK ID) that can remind us of the specified pass phrase. Both the pass phrase and KPK ID are read interactively.
