Not heaving read the code.... so just blindly guessing.
Since there are the additional keyslots,... and especially the data
alignment padding probably yes,... unless there are checks whether these
are e.g. all 0x0.
Anyway... who should put they key in such a place? If you're already
that far, that some evil application is running with enough rights on
your system to do that,... you're screwed anyway, and nothing can help
you with that.
