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 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.
