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

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