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

 #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 ");" 

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.

The handle to the hash object instance whose hash value should be signed. Indicates the length of the hash value data provided at the parameter rgbHashValue. A pointer to the hash value data.

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.

Tspi_Hash_SetHashValue conforms to the Trusted Computing Group Software Specification version 1.1 Golden

Tspi_Hash_UpdateHashValue(3), Tspi_Hash_Sign(3), Tspi_Hash_GetHashValue(3).
