Text protocols

In plain text protocols, the bit stream is organised as a sequence of characters or text strings, e.g. Unicode or ASCII. So the two computers are exchanging textual messages. Example: number 20020 is represented by five characters (5 bytes).

Pros and cons:

• interoperability between multiple platforms and runtimes that adhere to open and well-known standards: JSON, XML.
• results in larger size messages
• can be easily, inspected, read, debugged

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.
