NAME
       Tspi_Data_Seal - encrypt a data blob in a mannar that is only
       decryptable by Tspi_Data_Unseal on the same system.

       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
