🔓 sclient (Golang, Node)

Unwrap remote tls connections and serve locally
  • You can expose whatever.com:443 as localhost:3000 and then connect with telnet or netcat.
  • I wrote simply this because ssh -o ProxyCommand "sclient %h:443" example.com can fit in documentation on a single line while ssh -o ProxyCommand "openssl s_client -connect %h:443 -servername %h -quiet" example.com does not, and is hard to remember.
