       TSS_RESULT Tspi_Key_CreateMigrationBlob(TSS_HKEY hKeyToMigrate,		TSS_HKEY hParentKey,
					       UINT32	ulMigTicketLength,	BYTE*	 rgbMigTicket,
					       UINT32*	pulRandomLength,	BYTE**	 prgbRandom,
					       UINT32*	pulMigrationBlobLength, BYTE**	 prgbMigrationBlob);

DESCRIPTION

       Tspi_Key_CreateMigrationBlob  returns a key blob containing an encrypted section, which will be different depending on the migration scheme
       indicated within the migration ticket previously created by the method Tspi_TPM_AuthorizeMigrationTicket().

PARAMETERS

   hKeyToMigrate
       Handle of the key object to migrate.

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

   ulMigTicketLength
       The length (in bytes) of the rgbMigTickey parameter.

   rgbMigTicket
       Pointer to memory containing the migration ticket (migration public key and its authorization digest).

   pulRandomLength
       On successful completion this parameter returns the random data length returned at the parameter prgbRandom.

   prgbRandom
       On successful completion this parameter returns the random data.

   pulMigrationBlobLength
       On successful completion this parameter returns the length of the migration blob data returned at the parameter prgbMigrationBlob.

   prgbMigrationBlob
       On successful completion this parameter returns the migration data blob.

RETURN CODES

       Tspi_Key_CreateMigrationBlob returns TSS_SUCCESS on success, otherwise one of the following values are returned:

       TSS_E_INVALID_HANDLE - Either hKeyToMigrate, hParentKey or rgbMigTicket are invalid parameters.

       TSS_E_BAD_PARAMETER - One of the passed parameters is wrong.

       TSS_E_KEY_NO_MIGRATION_POLICY - No migration policy picked.

       TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
