xHTTP Cutting-Edge Transport

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

SNI: Direct Match (Standard TLS) Port 443 (Standard HTTPS) uTLS: 16879332 (Active)

This node utilizes xHTTP transport — a state-of-the-art Xray transport protocol that offers maximum censorship resistance against active probing and DPI filters.

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 (kala.fortresshost.ir): SNI matches target server hostname — clean standard TLS handshake with no cross-domain mismatch.

uTLS Handshake Security Analysis (16879332): Emulating 16879332 TLS parameters to protect against passive fingerprinting.

Client Handshake Masking (uTLS): Emulating 16879332 TLS parameters to protect against passive fingerprinting.
