Good VPN for seeding Torrents?

Both HTTP and SOCKS proxies offer no encryption.

Do i need any other program for that or can AirVPN do it all by itself?

I do not think I have seen that feature on AirVPN last I used them.

so its useless for me right?

Do you know of any that can do it and support port forwarding?

If you care about your privacy, yes. If used you have to make sure that either the application that uses the proxy has encryption or you’re using a VPN together with it.
