OAUTH2

The Problem

I’m a web app that wants to allow other web apps access to my users’ information, but I want to ensure that the user says it’s ok.

The Solution

I can’t trust the other web apps, so I must interact with my users directly. I’ll let them know that the other app is trying to get their info, and ask whether they want to grant that permission. Oauth defines a way to initiate that permission verification from the other app’s site so that the user experience is smooth. If the user grants permission, I issue an AuthToken to the other app which it can use to make requests for that user's info.

Note on encryption

Oauth2 has nothing to do with encryption -- it relies upon SSL to keep things (like the client app’s shared_secret) secure.

	Somebody was saying on the forums a while back that
	they felt like the code was too messy and... again I
	really wanna stress the fact that I don't really wanna
	try to tell people that the way they code is wrong
	because, you know, I feel that just leads to a lot of
	pedantic arguments that aren't usually constructive...

	But what I can say is: nobody, in my mind, _nobody_
	should be thinking that this code is "messy". This code
