TPM Handle Exception

Posted: 07-14-2008, 07:12 AM
I am trying to perform a TPM_Seal operation on some data. My platform
is Vista SP1 and the chip is Infineon (TPM 1.2)

On Calling the TPM_Seal operation the TBS is returning a strange error
code of 0x80280401 which is "Invalid Handle". The key is already
loaded in the TPM and Im using the same handle returned by the TPM.
Most of the other operations are fine including use of OIAP / OSAP
sessions and / or any other key.
Any ideas would be appreciated.
