Tspi_Key_ConvertMigrationBlob - create a wrapped key from a migration blob


#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_Key_ConvertMigrationBlob(TSS_HKEY hKeyToMigrate, TSS_HKEY hParentKey, UINT32 ulRandomLength, BYTE* rgbRandom, UINT32 ulMigrationBlobLength, BYTE* rgbMigrationBlob);


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.


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.


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.


Tspi_Key_ConvertMigrationBlob conforms to the Trusted Computing Group Software Specification version 1.1 Golden
