                                               UINT32   ulMigTicketLength,      BYTE*    rgbMigTicket,

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.
