+ EFI_HASH2_PROTOCOL as defined in UEFI 2.5.
+ The EFI Hash2 Service Binding Protocol is used to locate hashing services support
+ provided by a driver and to create and destroy instances of the EFI Hash2 Protocol
+ so that a multiple drivers can use the underlying hashing services.
+ EFI_HASH2_PROTOCOL describes hashing functions for which the algorithm-required
+ message padding and finalization are performed by the supporting driver.
