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:

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

Connect via Telnet

$ telnet localhost 3000

Connect via netcat (nc)

$ nc localhost 3000

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

Install

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

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

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

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)

Bridge between telebit.cloud and local port 3000.

sclient telebit.cloud 3000

Same as above, but more explicit

sclient telebit.cloud:443 localhost:3000

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

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