experimenting a bit with the tpm engine (openssl_tpm_engine-0.4.2). My
objective is to see how easy it is use this engine with openssl-1.0.1.
Since the README file states that openssl-0.9.8 is a requirement I
started using that openssl version. However, I have tried to use the tpm
engine with three different openssl-0.9.8 versions, but all three
crashes with different call stacks, when using the basic example from
the README file (Create a self-signed cert using the TPM engine). I'm
starting to suspect that I have overseen something fundamental. Is the
openssl-tpm-engine supposed to work on 64 bit machines? Or is there
something else I need to consider?<br><br>Below is some additional info on the crashes I'm seeing.
