TSS_RESULT Tspi_Data_Seal(TSS_HENCDATA hEncData, TSS_HKEY hEncKey,
UINT32 ulDataLength, BYTE* rgbDataToSeal,
TSS_HPCRS hPcrComposite);

DESCRIPTION

Tspi_Data_Seal encrypts a data blob in a mannar that is only
decryptable by Tspi_Data_Unseal on the same system. The data blob is
encrypted using a public key operation with the nonmigratable key
addressed by the given encryption key object.

PARAMETERS

hEncData
Handle of the data object which contains the sealed data on
successful completion of the command.

hEncKey
Handle to the key object addressing the nonmigratable key which is
used to encrypt the data.

ulDataLength
The Length (in bytes) of the rgbDataToSeal parameter.

rgbDataToSeal
Pointer to memory containing the data to be encrypted.

hPcrComposite
Handle of the PCR Composite object specifying the PCRs which are part
of the sealed data blob. Set to NULL, if the encrypted data should
only be bound to the system and PCRs are not of interest.

RETURN CODES

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

TSS_E_INVALID_HANDLE - One of the following parameters hEncData,
hEncKey, rgbDataToSeal is invalid.

TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.

CONFORMING TO

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