Standard TLS Encryption (WS)

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

SNI: Direct Match (Standard TLS) Port 443 (Standard HTTPS) uTLS: 16928857 (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 (uitestdfgrew-production.up.railway.app): SNI matches target server hostname — clean standard TLS handshake with no cross-domain mismatch.

uTLS Handshake Security Analysis (16928857): Emulating 16928857 TLS parameters to protect against passive fingerprinting.

Client Handshake Masking (uTLS): Emulating 16928857 TLS parameters to protect against passive fingerprinting.
