NAME
Tspi_TPM_StirRandom - add entropy to the TPM random number generator
SYNOPSIS
#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>
#include <tss/tss_typedef.h>
#include <tss/tss_structs.h>
#include <tss/tspi.h>
TSS_RESULT Tspi_TPM_StirRandom(TSS_HTPM hTPM, UINT32 ulEntropyDataLength, BYTE* rgbEntropyData);
DESCRIPTION
Tspi_TPM_StirRandom adds entropy to the TPM random number generator for
the purpose of generating better random numbers. The entropy variable
should assigned an appropriately seeded random number before this func-
tion is called.
PARAMETERS
hTPM
The hTPM parameter is used to specify the handle of the TPM object. The
command to get the TPM to test itself will be sent here.
ulEntropyDataLength
The ulEntropyDataLength parameter is the length in bytes of the rgbEn-
tropyData parameter.
rgbEntropyData
The rgbEntropyData parameter is a pointer to the entropy data.
RETURN CODES
Tspi_TPM_StirRandom returns TSS_SUCCESS on success, otherwise one of
the following values is returned:
TSS_E_INVALID_HANDLE
hTPM is not a valid handle.
TSS_E_INTERNAL_ERROR
An internal SW error has been detected.
TSS_E_BAD_PARAMETER
One or more parameters is bad.
CONFORMING TO
Tspi_TPM_StirRandom conforms to the Trusted Computing Group Software
Specification version 1.1 Golden
