//
//      This file describes the DPAPI BackupKey RPC interface, which is
//      used by DPAPI when comunicating with the domain controller.
//      This interface is used for three purposes: 
// 
//        1. To retrieve the domain backup public key (Whistler only).
//        2. To backup master keys.
//        3. To restore previously backed up master keys.
