The /etc/ssh/sshd_config file on my fedora 27 partition says:
# To opt out, uncomment a line with redefinition of CRYPTO_POLICY= # variable in /etc/sysconfig/sshd to overwrite the policy. # For more information, see manual page for update-crypto-policies(8).
But there is no CRYPTO_POLICY environment variable setting in /etc/sysconfig/sshd or in supposed system wide file /etc/crypto-policies/back-ends/openssh-server.config I see referenced in the sshd.service definition.
