What is Reality?
Published: 2026-08-25 · Updated: 2026-08-25
Reality is a transport profile for VPN connections over TLS 1.3. The client verifies the server by its public key instead of a certificate authority chain, so the server does not need to issue and maintain its own certificates. In Vinipuch, Reality works together with the VLESS protocol on the sing-box core.
Classic TLS assumes the server presents a certificate issued by a certificate authority. Reality replaces that with verification against a pre-known server public key: the client knows exactly who it is talking to, and the operator does not need to run certificate infrastructure.
For the connection this means standard modern TLS 1.3 encryption and a fast handshake. For you it means fewer moving parts: the configuration arrives as a single profile link and updates automatically.
Transport details evolve with core updates; the current configuration is always the one your remote profile delivers.
