[TrouSerS-users] Failing to unseal data immediately after sealing

[Cornelius N. <co...@ya...>]

I am running some tests on the code I have written to exercise some TPM features. 
This is my code snippet:

        result = Tspi_PcrComposite_SetPcrValue( hPcrComposite, 9, 20, rgbPcrValue );
        if ( result != TSS_SUCCESS )         exit(result);

        result = Tspi_PcrComposite_SetPcrValue( hPcrComposite, 10, 20, rgbPcrValue );
        if ( result != TSS_SUCCESS )         exit(result);

        result = Tspi_Data_Seal( hEncData, hSRK, ulDataLength, rgbDataToSeal, pcrObj->getHPCRS() );
        if ( result != TSS_SUCCESS )     exit(result);
        else
        {
            //try unsealing
            result = Tspi_Data_Unseal(hEncData, hSRK, &unsealedDataLength, &unsealedDataBlob);
            if(result != TSS_SUCCESS)    cout<<ERROR_CODE(result);
        }

This prints out 24, which I understand corresponds to TPM_WRONGPCRVAL.

Does any have an idea what might be happening here?
