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.
