Restrict to TLS v1.3

[Vladimir Levijev]

Hi,

I'd like to restrict the application to only work with TLS version >=
1.3 . That is, any attempt to establish a connection with LTS v1.2 and
less should be dropped. I came up with the following being enough to
ensure that:

SSL_CTX_set_min_proto_version=TLSv1.3

But could you confirm that it is so? Perhaps there are more things I should do?

TIA,

VL
