NAME
Tspi_Hash_UpdateHashValue - update the 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_UpdateHashValue(TSS_HHASH hHash, UINT32 ulDataLength, BYTE* rgbData);
DESCRIPTION
Tspi_Hash_UpdateHashValue updates the hash value of a hash object with
new information. If the object was created with the flag TSS_HASH_OTH-
ER, then this method will return an error. The object can't be modified
after Tspi_Hash_SetHashValue, Tspi_Hash_GetHashValue, Tspi_Hash_Sign,
or Tspi_Hash_VerifySignature have been called on it.
PARAMETERS
hHash
The handle to the hash object instance whose hash value should be
signed.
ulDataLength
Indicates the length of the data provided at the parameter rgbData.
rgbData
A pointer to the data.
RETURN CODES
Tspi_Hash_UpdateHashValue 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_UpdateHashValue conforms to the Trusted Computing Group Soft-
ware Specification version 1.1 Golden
