Xray REALITY over RAW / TCP

Cryptographic resistance profile and Deep Packet Inspection (DPI) evasion analysis

SNI: High-Profile Global SNI (Probing Risk) Port 443 (Standard HTTPS) uTLS: 13785448 (Active)

This node utilizes RAW / TCP transport with Xray REALITY. It applies TLS-in-TLS masking to eliminate identifiable proxy signatures, making the handshake look like a legitimate browser connection.

Network Port Analysis: Port 443 is the universal standard for secure HTTPS traffic. Firewalls and ISPs cannot block it without disrupting regular web access.

SNI Masking Analysis (google.com): High-profile global domains (google.com) are monitored by censorship systems; Reality endpoints with these SNIs face aggressive active probing.

uTLS Handshake Security Analysis (13785448): Emulating 13785448 TLS parameters to protect against passive fingerprinting.

Flow Technology: Flow "xtls-rprx-vision" (XTLS Vision Seed) dynamically obfuscates packet padding, preventing DPI systems from measuring TLS ClientHello length patterns.

Client Handshake Masking (uTLS): Emulating 13785448 TLS parameters to protect against passive fingerprinting.
