    The requirement of message security and sender verification is pretty obvious when it comes to chat. With email SMTP, a digital signing as proof of sender is included. But what about for mobile and web chat applications? How can we ensure that a user is identified and authorized?

    In this tutorial, we’ll show you how to build chat user identification using 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.
