# Tspi\_Hash\_SetHashValue(3)

Sets the hash value of a hash object for non-SHA1 hash objects.

TCG Software Stack Developer's Reference

## NAME

Tspi\_Hash\_SetHashValue - Sets the hash value of a hash object for non-SHA1 hash objects.

## 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_SetHashValue(TSS_HHASH hHash, UINT32 ulHashValueLength, BYTE* rgbHashValue);
```

## DESCRIPTION

**Tspi\_Hash\_SetHashValue** sets the hash value of a hash object. If the object was created with the flag TSS\_HASH\_OTHER, then the hash identifier has to be set by calling **Tspi\_SetAttribData** to perform the sign operation.

## PARAMETERS

### hHash

The handle to the hash object instance whose hash value should be signed.

### ulHashValueLength

Indicates the length of the hash value data provided at the parameter *rgbHashValue*.

### rgbHashValue

A pointer to the hash value data.

## RETURN CODES

**Tspi\_Hash\_SetHashValue** 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\_SetHashValue** conforms to the Trusted Computing Group Software Specification version 1.1 Golden
