Chatroom Security

Chat User Identification with Digital Signature Message Verification

You can identify the sender by creating a Unique ID as well as a Name attached to the message payload of the chat conversation. This is similar to IRC strategies but a bit more simplistic.

var user_id      = PUBNUB.uuid();
var user_name    = name.value;
var user_message = input.vaule;
