In not so distant past (v6.5.0~3) I've updated the private key we use for virnettls* tests. Back then I was driven by Fedora 33 change which deprecated RSA-1024 which we used back then. I generated an EC-384 key which was fine as it was considered strong enough until RHEL-9 came along. RHEL-9 no longer considers any of EC keys strong enough (for key exchange) and thus we're back to RSA, but this time with 2048 bits. Generated by this cmd line:
I'd go for 4096 bits to stay ahead a bit.

My quick google search yielded just some JDK changes for improving the implementation of EC algorithms:
https://bugs.openjdk.java.net/browse/JDK-8208698
but nothing that would state it's no longer secure or anything.
Either way.

Alright, so after more debugging this turned out to be a bug in crypto-policies package in RHEL-9. It's fixed by the following commit: https://gitlab.com/redhat-crypto/fedora-crypto-policies/-/commit/a5e64bb9a4a... And I can confirm that with that commit the virnettlssessiontest passes again. Thus I think this patch can be discarded. Michal
