NAME
Tspi_Hash_GetHashValue - get the current hash value of a hash object
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_Hash_GetHashValue(TSS_HHASH hHash, UINT32* pulHashValueLength, BYTE** prgbHashValue);
DESCRIPTION
Tspi_Hash_GetHashValue gets the hash value of a hash object. Tspi_Con-
text_FreeMemory must be used to clean up after this function, as memory
is allocated for the prgbHashValue data.
PARAMETERS
hHash
The handle to the hash object instance whose hash value should be
signed.
pulHashValueLength
Receives the length of the hash value data returned at the parameter
prgbHashValue.
prgbHashValue
Receives a pointer to the hash value data.
RETURN CODES
Tspi_Hash_GetHashValue returns TSS_SUCCESS on success, otherwise one of
the following values is returned:
TSS_E_INVALID_HANDLE
hHash 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.
TSS_E_HASH_INVALID_LENGTH
Hash length is inconsistent with hash algorithm.
TSS_E_HASH_NO_DATA
Hash object has no internal hash value.
CONFORMING TO
Tspi_Hash_GetHashValue conforms to the Trusted Computing Group Software
Specification version 1.1 Golden
