Add an encryption option

Currently traffic is encrypted, but data is not

Thanks for atom-pair @jpatel531 - could you expand on the difference between traffic vs. data?

[jalcine]

Perhaps this?

Traffic is over HTTPS, but data's over cleartext?
Maybe using something like OTR to start off (it's not the most secure) and upgrading to use NaCl to use a PSK to encrypt the data.

Of course, speed + performance considerations come into play.

So currently you may have some of or all of the code your sharing at rest on Pusher server in plain text?
