This simple crate establishes a TLS connection to a specified target and creates a TCP server that allows you to communicate with the TLS server over a raw, unencrypted TCP socket.
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.
Simply download and compile the Rust binary using cargo install:
$ cargo install tls-tunnelPass 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.
$ tls-tunnel https://httpbin.orgThe 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.
