ParallelHash256HashAll()

BOOLEAN EFIAPI ParallelHash256HashAll	(	IN CONST VOID *	Input,
		IN UINTN	InputByteLen,
		IN UINTN	BlockSize,
		OUT VOID *	Output,
		IN UINTN	OutputByteLen,
		IN CONST VOID *	Customization,

Parallel hash function ParallelHash256, as defined in NIST's Special Publication 800-185, published December 2016.

Parameters

[in]	Input	Pointer to the input message (X).
[in]	InputByteLen	The number(>0) of input bytes provided for the input data.
[in]	BlockSize	The size of each block (B).
[out]	Output	Pointer to the output buffer.
[in]	OutputByteLen	The desired number of output bytes (L).
[in]	Customization	Pointer to the customization string (S).
[in]	CustomByteLen	The length of the customization string in bytes.

Return values

TRUE	ParallelHash256 digest computation succeeded.
FALSE	ParallelHash256 digest computation failed.
FALSE	This interface is not supported.
