Tor-Go

A Tor client implementation in pure Go.

Features

• Tor v3 client protocol (link handshake, circuit building, stream multiplexing)
• 3-hop onion-routed circuits with ntor key exchange
• v3 onion service client (.onion address resolution and connection)
• SOCKS5 proxy server for transparent traffic routing
• Directory authority consensus fetching with cryptographic signature validation
• Bandwidth-weighted relay selection (guard, middle, exit)
• Minimal dependencies — only golang.org/x/crypto and filippo.io/edwards25519
