VPN leaks test

Description

The plugin contains the leaks test package:
– DNS leak test
– WEBrtc IP leak test
– Email IP leak test
– Torrent IP leak test

The plugin integrates with https://bash.ws, a 3rd party service, to have it do the VPN testing.
The service is free to use and does not require an API key and/or registration, see terms of use https://bash.ws/terms.
The plugin essentially makes a remote request (POST) to a service URL, passing an user IP address as a parameter.
Depending on the test the following additional data are received by the service:
– DNS leak test: the plugin does several DNS-lookup requests to the service;
– WEBrtc IP leak test: the plugin receives additional IPs from the Internet browser;
– Email IP leak test: the plugin asks user to send an empty email to the service;
– Torrent IP leak test: the plugin asks user to download a torrent file from the service.
