XkeyScore can decrypt my tunneled connection with aes-256, sha256? I knew the nsa was good but not that good... where does it say it decrypts the vpn tunnels of any kind on the slide though I'm curious -_-
Is your goal to be anonymous on your web? Because the traffic isn't encrypted when it leaves the VPN and your browser cookies (or various apps phoning home) will make your identity obvious.
No my goal is simply to evade the NSA wiretaps as well as my ISP who has recently started messing up my internet connection whenever I torrent, so I vpn overseas and torrent. But yes you are correct, in order to browse privately you should really use tails or something along with vpn and avoid say logging into facebook or anything linked to your identity.
