What It Does

GooseRelayVPN is a SOCKS5 proxy that tunnels raw TCP through a Google Apps Script web app to a self-hosted VPS exit server. The traffic path:

Browser/App
  -> SOCKS5 (127.0.0.1:1080)
  -> AES-256-GCM encrypted frames
  -> HTTPS to Google edge IP (SNI=www.google.com, Host=script.google.com)
  -> Apps Script doPost() — dumb forwarder, never sees plaintext
  -> Your VPS :8443/tunnel — decrypts, dials real target
  <- Same path in reverse via long-polling
