VPN Key Decoder & Security Analyzer
Paste any vless://, vmess://, trojan://, ss://, hy2:// or Telegram proxy link for an immediate security and DPI resistance breakdown.
Frequently Asked Questions
Troubleshooting, protocols, and client setup guidance
How does the online VPN key decoder and analyzer work? ▼
The analyzer functions entirely inside your web browser without sending key data to any remote server. It parses encryption parameters, transport protocols, ports, Reality camouflage (pbk, sid, flow, sni), and evaluates configuration resistance against DPI filtering.
Is it secure to inspect private keys using this tool? ▼
Yes, 100% secure. Parsing and cryptographic evaluation execute completely on the client side using browser Web Crypto APIs and standard JavaScript. Keys, tokens, and server addresses are never transmitted to our backend.
What does the Security Score from 0 to 100 measure? ▼
The score assesses four critical anti-censorship factors: standard port usage (port 443 grants +25 pts), protocol cipher strength (VLESS Reality yields +35 pts), uTLS handshake fingerprinting (Firefox/Safari provides +25 pts against carrier heuristics), and SNI camouflage sanity.
Why is VLESS Reality recommended for high-censorship environments? ▼
Reality avoids dedicated TLS certificates by borrowing legitimate TLS 1.3 handshake parameters from high-reputation foreign domains. Firewalls observe genuine encrypted web traffic without distinguishing proxy data.
