Xray REALITY over RAW / TCP

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

SNI: Low-Profile SNI (Optimal for Reality) Port 8443 (Alternative HTTPS) uTLS: 16439000 (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 8443 is a recognized alternative port for TLS/HTTPS services, typically permitted across most carrier networks.

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

uTLS Handshake Security Analysis (16439000): Emulating 16439000 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 16439000 TLS parameters to protect against passive fingerprinting.

REALITY Cryptography: Public key (pbk) pinned on server • Short ID (sid: a1b2c4d4a1b2c5d5) validated for session authorization
