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

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 han‐
       dle to the created key object.

PARAMETERS

   hContext
       The hContext parameter is the handle of the context object.

   hUnwrappingKey
       The hUnwrappingKey parameter is the handle of the key object which should be used to unwrap the  key  in‐
       formation associated with rgbBlobData.

   rgbBlobData
       The rgbBlobData parameter is the wrapped key to load.

   phKey
       The phKey parameter receives the handle of the key object representing the loaded key.

RETURN CODES

       Tspi_Context_LoadKeyByBlob  returns  TSS_SUCCESS on success, otherwise one of the following values is re‐
       turned:

       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.
