Versions:
go-p2ptunnel 0.2.32, published by Chen Jia, is a lightweight network utility that creates encrypted, peer-to-peer TCP tunnels across private or public networks without requiring a central server. Built on the libp2p stack, the application establishes secure channels that can ride over QUIC, plain TCP, WebSocket, or WebTransport, automatically selecting the most efficient path while the Noise protocol keeps all traffic confidential. Because every node is identified only by its cryptographic node-ID, users behind carrier-grade NAT or without a public IP can still reach one another by exchanging those IDs; direct IP-plus-protocol targeting is also supported when conditions allow. The single-binary tool stores its Ed25519 private key in a local user.key file—deleted keys are regenerated on restart—so the same identity can be reused or discarded at will. Typical deployments include linking dispersed development environments, exposing a local database or web service to a remote collaborator, chaining several tunnels to hop across layered intranets, or providing a quick encrypted back-channel for IoT devices. The program runs on any modern Windows workstation and is distributed in the Network/Tunneling category. Only one version, 0.2.32, is currently offered. go-p2ptunnel is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, guaranteeing the latest build and supporting batch installation alongside other applications.
