Hi,

Thanks for taking this to the openvpn-devel list.

The proposed patch doesn't follow our approach of hiding the openssl
1.0/1.1 API compatibility mess inside openssl_compat.h, so we'll have to
rework it before including it.  I will pick this up some time soon, but
have very limited access to internet (nor time to hack on openvpn)
currently, so it might take me a few weeks.  But there won't be a
release before that time anyway, and in the mean time users that are
really caught by this can put "@SECLEVEL=1" inside their --tls-cipher to
work around this if I understand the docs correctly [0].

@Kurt: for future reference, how are we supposed to be aware of these
kind of deprecated functions, and how do we know what The New Right Way
is?  https://wiki.openssl.org/index.php/OpenSSL_1.1.0_Changes for
example does not mention this at all.
