tpm2tss-genkey: could not load tpm2tss engine

When I run

tpm2tss-genkey --alg=ecdsa mykey --ownerpw=xxxx

I get this error message:

Could not load tpm2tss engine

Also openssl gives error messages:

[fansari@bat keys]$ openssl engine -t -c tpm2tss

There is no tpm2tss.so in /usr/lib64/engines-3. Why is it expected there? Is this a misconfiguration or some package missing?

But I find it in /usr/lib64/engines-1.1.

I noticed that the packages are "fc35". This is strange.

tpm2-tss-engine-1.1.0-3.fc35.x86_64
tpm2-tss-engine-utilities-1.1.0-3.fc35.x86_64

I have Fedora 36 Silverblue and all other tpm2 pakages have "fc36".

tpm2-tss-3.2.0-3.fc36.x86_64
tpm2-abrmd-selinux-2.3.1-5.fc36.noarch
tpm2-pkcs11-tools-1.7.0-2.fc36.x86_64
tpm2-abrmd-2.4.1-1.fc36.x86_64
tpm2-tools-5.2-2.fc36.x86_64
tpm2-pkcs11-1.7.0-2.fc36.x86_64

These openssl packages are installed:

openssl-pkcs11-0.4.12-2.fc36.x86_64
openssl-libs-3.0.5-1.fc36.x86_64
openssl1.1-1.1.1q-1.fc36.x86_64
openssl-3.0.5-1.fc36.x86_64

I guess I see the problem now: this is deprecated and was replaced by tpm2-openssl. But I don't find this for fc36.

I will uninstall tpm2-tss-engine-utilities and leave this topic for now.

Yes, tpm2-tss-engine is an engine for OpenSSL1.1.x OpenSSL3.0 now uses the provider-API with tpm2-openssl
