|
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.
