NAME¶

Tspi_Context_LoadKeyByBlob - load a key into the TPM using the key's blob.

SYNOPSIS¶

#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>

TSS_RESULT Tspi_Context_LoadKeyByBlob(TSS_HCONTEXT hContext,     TSS_HKEY hUnwrappingKey,
                                      UINT32       ulBlobLength, BYTE*    rgbBlobData,
                                      TSS_HKEY*    phKey); 

DESCRIPTION¶

Tspi_Context_LoadKeyByBlob creates a key based on the information gotten by the key blob. It then loads the key into the TPM, which unwraps the key blob by using the key associated with hUnwrappingKey. The key blob addressed by hUnwrappingKey must have been already loaded into the TPM. This function returns a handle to the created key object.

PARAMETERS¶

RETURN CODES¶

Tspi_Context_LoadKeyByBlob returns TSS_SUCCESS on success, otherwise one of the following values is returned:

TSS_E_INVALID_HANDLE

hContext 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.
