TSS_RESULT Tspi_Key_ConvertMigrationBlob(TSS_HKEY hKeyToMigrate,         TSS_HKEY hParentKey,
                                         UINT32   ulRandomLength,        BYTE*    rgbRandom,
                                         UINT32   ulMigrationBlobLength, BYTE*    rgbMigrationBlob);

DESCRIPTION

Tspi_Key_ConvertMigrationBlob takes the migration blob built by Tspi_Key_CreateMigrationBlob using the migration scheme TSS_MS_MIGRATE and creates a normal wrapped key. The resulting normal wrapped key blob is stored in the instance associated with hKeyToMigrate and may be retrieved from that instance by Tspi_GetAttribData.

PARAMETERS

hKeyToMigrate

The handle of the key object to convert.

hParentKey

Handle to the parent key related to the key addressed by hKeyToMigrate.

ulRandomLength

Length of random data provided at the parameter rgbRandom.

rgbRandom

Random data as returned together with the migration blob by the method Tspi_Key_CreateMigrationBlob.

ulMigrationBlobLength

Length of the migration blob data provided at the parameter rgbMigrationBlob.

rgbMigrationBlob

Migration blob data as returned by a previously called method Tspi_Key_CreateMigrationBlob.

RETURN CODES

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

TSS_E_INVALID_HANDLE: hKeyToMigrate or hParentKey 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.
