   The EFI Hash Service Binding Protocol is used to locate hashing services support 
   provided by a driver and to create and destroy instances of the EFI Hash Protocol 
   so that a multiple drivers can use the underlying hashing services.
-  The EFI Service Binding Protocol defines the generic Service Binding Protocol functions.
