}Automated Verification Routine
xray run -test -conf /etc/xray/config.json
Eliminates self-signed TLS fingerprinting by proxying client hello payloads to legitimate upstream TLS servers.
When a client establishes a connection on port 443, REALITY dynamically negotiates TLS 1.3 using an authentic third-party public certificate. Unauthenticated probes receive the real upstream destination response (such as Cloudflare or Apple), preventing active probing and DPI heuristic classification.
