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
