Re: [Tpm4java-users] PLEASE HELP! TPMException: Bad return code 33 The descryption process did not complete

[Frederic S. <st...@se...>]

Hi Andr=E9s,

sorry, I have no clue either. I suggest that you try your code with the=20
TPM emulator to verify whether your code is okay or if it is a problem=20
with your HW TPM. The problem is that most of the available TPMs are not =

conform to the TCG specification and therefore many problems occur.

best regards
Frederic
