I've read several tutorials, but not totally sure.
If I'll set up my own SOCKS5 proxy server on VPS, configure it to use username and password. Will this credentials be safe while authentication on proxy via public wi-fi for example?
If no, how it works for paid proxy providers?
I know about VPN and SSH-tunneling. But I think they are too complicated for using on mobile devices and also leads to additional power consumption for keeping connections alive.
