VLESS + Reality: why this protocol is invisible to censorship

Deep packet inspection (DPI) has learned to detect most VPN protocols by characteristic handshake signatures. Reality solves this radically: it borrows the TLS handshake of a real third-party website.

When you connect, the traffic looks like a request to a popular resource with a genuine certificate. To an observer it is indistinguishable from ordinary HTTPS.

That's why Che VPN uses VLESS + Reality as the primary protocol, while AI Shield automatically switches to Shadowsocks 2022 or Hysteria 2 on issues.
