Xray REALITY over RAW / TCP

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

SNI: Low-Profile SNI (Optimal for Reality) Port 23576 (Non-standard • High Risk) uTLS: 13776695 (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: Non-standard port (23576). Mobile operators and restricted whitelist networks frequently drop non-443/8443 traffic at the firewall layer.

SNI Masking Analysis (fuck.rkn): Masked under a low-profile external domain (fuck.rkn), which effectively reduces detection risk from automated DPI heuristics.

uTLS Handshake Security Analysis (13776695): Emulating 13776695 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 13776695 TLS parameters to protect against passive fingerprinting.

REALITY Cryptography: Public key (pbk) pinned on server • Short ID (sid: 01) validated for session authorization
