Chisel is a fast TCP/UDP tunnel, transported over HTTP, secured via SSH. Single executable including both client and server. Written in Go (golang). Chisel is mainly useful for passing through firewalls, though it can also be used to provide a secure endpoint into your network.
This is free and open source software.
Key Features
- Easy to use.
- Performant.
- Encrypted connections using the SSH protocol (via crypto/ssh).
- Authenticated connections; authenticated client connections with a users config file, authenticated .server connections with fingerprint matching.
- Client auto-reconnects with exponential backoff.
- Clients can create multiple tunnel endpoints over one TCP connection.
- Clients can optionally pass through SOCKS or HTTP CONNECT proxies.
- Reverse port forwarding (Connections go through the server and out the client).
- Server optionally doubles as a reverse proxy.
- Server optionally allows SOCKS5 connections.
- Clients optionally allow SOCKS5 connections from a reversed port forward.
- Client connections over stdio which supports ssh -o ProxyCommand providing SSH over HTTP.
