Standard TLS Encryption (WS)

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

SNI: Low-Profile SNI (Optimal for Reality) Port 443 (Standard HTTPS) uTLS: 10259518 (Active)

Standard TLS encryption channel over WS. Provides robust end-to-end data security suitable for networks with standard censorship policies.

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 (nat12.9966338.xyz): Masked under a low-profile external domain (nat12.9966338.xyz), which effectively reduces detection risk from automated DPI heuristics.

uTLS Handshake Security Analysis (10259518): Emulating 10259518 TLS parameters to protect against passive fingerprinting.

Client Handshake Masking (uTLS): Emulating 10259518 TLS parameters to protect against passive fingerprinting.
