Crypto Policies are means of enforcing certain cryptographic settings for
selected applications including OpenSSL. OpenSSL is by default configured to
modify its configuration based on currently configured Crypto Policy.
Editing the Crypto Policy back-end is not recommended.
Check the crypto-policies(7) man page and choose a policy that configures TLS
protocol to version 1.2 or higher, for example DEFAULT, FUTURE or FIPS policy.
Or create and apply a custom policy that restricts minimum TLS version to 1.2.
For example for versions prior to crypto-policies-20210617-1.gitc776d3e.el8.noarch
this is expected:
$ sudo grep -i MinProtocol /etc/crypto-policies/back-ends/opensslcnf.config
MinProtocol = TLSv1.2
Or for version crypto-policies-20210617-1.gitc776d3e.el8.noarch and newer this is
expected:
$ sudo grep -i MinProtocol /etc/crypto-policies/back-ends/opensslcnf.config
TLS.MinProtocol = TLSv1.2
DTLS.MinProtocol = DTLSv1.2
