tls-tunnel

Rust TLS over TCP tunnel

This simple crate establishes a TLS connection to a specified target and creates a TCP server that allows you to tunnel TCP to the target over a standard TLS connection.

This is useful for environments where TLS connections are not feasible at runtime. Some examples:

• Using a CONNECT proxy from a language that doesn't support CONNECT-over-TLS.
• Legacy runtimes which do not support HTTPS but do support HTTP.
• Interoperability of legacy VoIP, IRC or FTP clients which do not support TLS with servers which do.

Install

Simply download and compile the Rust binary using cargo install:

bash $ cargo install tls-tunnel

Run

Pass the target host and port as an argument when running using cargo or the compiled binary. If not provided, the tunnel will default to httpbin.org:443 for demo purposes.

bash $ tls-tunnel httpbin.org:443

The server will automatically choose a port to listen on. It defaults to port 1025 and will increment by one until it finds an available port to bind to.
