Thank you Ken, but I am OK just using Microsoft's TPM Simulator.exe, which
I now got working after modifying tpm2-tss/src/util/io.c. The MS simulator
only listens on IPv4 and io.c may fail since the list from getaddrinfo may
return IPv6 address before IPv4 address. I did not look into the logic, I
just did a quick fix:
        if (*sock == INVALID_SOCKET
           || p->ai_family != AF_INET) //PATCH MS sim listens on IPv4 only
            continue;

FYI Ken has a staged version that&#39;s ready to go with OpenSSL 3.0.1:<br>

[kgold] A bit of background.  The TPM reference code (from the specification) sometimes looks inside a OpenSSL structure that was later made opaque.  Each time a new openssl version is released, I check to see if the structure has changed.  The #error message reminds me to check.  So far, we&#39;re good to 3.0.1.<br>
<br>
As Bill said, the staged version updated the check.<br>
