As far as that goes: my RHEL9 machine, with a perfectly vanilla install, has $ rpm -q python3 python3-3.9.25-7.el9_8.x86_64 $ rpm -q openssl openssl-3.5.5-4.el9_8.x86_64 So in the Red Hat universe I think we could safely expect a minimum of OpenSSL 3.5. But that doesn't matter much given that your list shows other LTS distros still on 3.0. regards, tom lane
