SWS - Secure WebSocket implementation over NACL(network and crypto library)

wss is to run websocket over tls/ssl, so many http websites are hard to run a secure ws/message system. 

But, SWS intends to run plain websocket over NACL, then http website can have secure message/socket system.

SWS has two versions:

Version 1: ws client and server will exchange NACL Box public without certification system.

Version 2: ws client and server will exchange NACL Box public with CA-signed certification system.

Both browser and node.js are supported:
