This addresses the issue that Stefan also pointed out. You have to
deal with the TPM error codes.
Hm, in the past I was told by Christoph not to use the ternary
operator. ÂHave things changed? ÂOther than removing the comment, the
only other difference is the return.
In the end it is a matter of personal preference, but I find the
quote version above using the ternary horribly obsfucated.
I fully agree that the return statement is an obsfucated mess and
not a good place at all for using ternary operator.

I have posted the v3 version that includes the suggested corrections by you and Stefan. Sorry for some delay.

Michal and Sachin, I would appreciate if you can test the v3 version, please ?

Thanks & Regards,
