sclient.go
==========

Secure Client for exposing TLS (aka SSL) secured services as plain-text connections locally.

Also ideal for multiplexing a single port with multiple protocols using SNI.

Unwrap a TLS connection:

```bash
$ sclient whatever.com:443 localhost:3000
> [listening] telebit.cloud:443 <= localhost:3000
```

Connect via Telnet

```bash
$ telnet localhost 3000
```

Connect via netcat (nc)

```bash
$ nc localhost 3000
```

A poor man's (or Windows user's) makeshift replacement for `openssl s_client`, `stunnel`, or `socat`.

Install
=======

### macOS, Linux, Windows

For the moment you'll have to install go and compile `sclient` yourself:

* <https://golang.org/doc/install#install>

```bash
git clone https://git.coolaj86.com/coolaj86/sclient.go.git
pushd sclient.go
go build sclient*.go
rsync -av sclient-cli /usr/local/bin/sclient
```

```bash
go run sclient*.go example.com:443 localhost:3000
```

Usage
=====

```bash
sclient [flags] <remote> <local>
```

* flags
  * -k, --insecure ignore invalid TLS (SSL/HTTPS) certificates
* remote
  * must have servername (i.e. example.com)
  * port is optional (default is 443)
* local
  * address is optional (default is localhost)
  * must have port (i.e. 3000)

Examples
========

Bridge between `telebit.cloud` and local port `3000`.

```bash
sclient telebit.cloud 3000
```

Same as above, but more explicit

```bash
sclient telebit.cloud:443 localhost:3000
```

Ignore a bad TLS/SSL/HTTPS certificate and connect anyway.

```bash
sclient -k badtls.telebit.cloud:443 localhost:3000
```
