  EFI_HASH_PROTOCOL as defined in UEFI 2.0.
 | 
						|
  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.
