The OpenVPN server-side authentication is done by using the --auth-user-pass-verify script available at http://kzaeunogz6s75ptgy6ifjzwwy75xdfenenswvrczd7mewxgrad5a.b32.i2p/conf/auth.sh.txt As you can see from the above three scripts, the only data ever sent from the nodes to the authentication server API is your token's sha512 hash, and it's always sent using HTTPS. On the node itself, logging is disabled for everything [root@singapore ~]# ls -la /var/log/
