rtc chat v2

A WebRTC chat service written in Go

rtc chat establishes end-to-end encrypted, P2P and relayed communication links.

Installation

You should have Go 1.1 installed.

Install the following modules:

go get github.com/mehrvarz/rtcchat2
go get github.com/steveyen/gkvlite
go get code.google.com/p/go.net/websocket

Initialize the callee service key/value flat file DB.

cd $GOPATH/src/mehrvarz/rtcchat2
go run rtcchat/gkvCreate.go

Run server without SSL keys (test mode)

rtc chat server should be run with SSL keys installed (see next section). For simple test purposes, you can run rtc chat server without SSL keys (and then use http instead of https):

go run rtcchat/main.go -secure=false

Run server with SSL keys (standard mode)

Create SSL keys for use with HTTPS:

mkdir keys && cd keys
openssl req -new -x509 -nodes -out cert.pem -keyout key.pem -days 100
(answer questions)
cd ..

Alternative: create symbolic links to your existing keys from /etc/nginx

mkdir keys && cd keys
ln -s /etc/nginx/cert.pem cert.pem
ln -s /etc/nginx/key.pem key.pem
cd ..

Note: the "keys" subfolder is expected to contain two files: "cert.pem" and "key.pem".

This is how your installation folder should look:

rtcchat2/

	html/
		index.html
		spinner.gif
		bootstrap.min.css
		...

	rtcchat/
		main.go
		gkvCreate.go
		...

	keys/
		key.pem
		cert.pem

	rtcSignaling.go
	calleeService.go
	callerService.go
	calleePersistKey.go
	udpProxy.go
	stun.go
	LICENSE
	...

To run rtc chat server:

go run rtcchat/main.go

Or simply:

./run

Test your server

  1. Open the following URL in two browser tabs:

    https://127.0.0.1:8077

    or: http://127.0.0.1:8077 for insecure test mode

  2. Enter the same 'secret word' in both browser tabs. You should see the two instances connect.
