Hello Josip,

I am not sure it is possible to implement what you want.  The PKI
encryption is Client based, thus unless the real (or original) Client
(FD) is involved, it is impossible to perform or change data encryption
in any way.  SD->SD transfers are only Copy and Migration jobs and not
original backups involving the Client, so there is no way the SD can do
anything with data encryption other than reading the data and either
sending it unmodified to an FD or writing it on some Volume.

Best regards,
Kern
