- The whole crypto section has been outsorted from the global section to
an extra page.
- Since --cipher is deprecated and will be handled via
--data-cipher-fallback, the VAR name and the index has been kept but
renamed from --cipher to --data-cipher-fallback. Old default AES-256-CBC
has also been kept.
- The new directive --data-ciphers has been introduced for RWs which negotiates
now between the GCM family and the new CHACHA20-POLY1305. All ciphers
can be combined.
- The new directive --data-ciphers substitutes --ncp-disable, there
--ncp-disable has been removed which fixes the deprecation warning in
the updated OpenVPN-2.5.0.
- While client generation the client version can be set which enables, if
client is >=2.5.0 a full cipher negotiation. Existing clients can also
subsequently be enhanced via edit.
- The new ciphers and HMACs as been completely integrated into N2N
environment without further modification.
Code for update process via update.sh needs to be integrated:
/usr/local/bin/openvpnctrl -k > /dev/null
if grep -q 'cipher' /var/ipfire/ovpn/server.conf; then
sed -i 's/cipher/data-ciphers-fallback/' /var/ipfire/ovpn/server.conf
fi
/usr/local/bin/openvpnctrl -s > /dev/null
