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 ob- ject was created with the flag TSS_HASH_OTHER, then the hash identifier has to be set by calling Tspi_SetAttribData to perform the sign opera- tion.

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
