RandGetBytes()

STATIC BOOLEAN EFIAPI RandGetBytes	(	IN UINTN	Length,
		OUT UINT8 *	RandBuffer
	)

Calls RandomNumber64 to fill a buffer of arbitrary size with random bytes. This is a shim layer to RngLib.

Parameters

[in]	Length	Size of the buffer, in bytes, to fill with.
[out]	RandBuffer	Pointer to the buffer to store the random result.

Return values

TRUE	Random bytes generation succeeded.
FALSE	Failed to request random bytes.
