Takes WireGuard/OpenVPN udp packets and encrypts them with XOR so it gets through the Kirsakht firewalls of Iran's internet.

Usage:

(server side, for example hetzner where your vpn server is on port 8443)

./udp2xor -forward 0.0.0.0:8444~127.0.0.1:8443 -timeout 1m

(client side, for example Iran)

./udp2xor -forward 0.0.0.0:8443~x.x.x.x:8444 -timeout 1m (where x.x.x.x is the ip of your germany server)

if you're using wireguard, make sure to set MTU to 1280 and if you're using openvpn make sure to set

keepalive 5 120

tun-mtu 1500

mssfix 1420

in your server.conf
