Use fernet tokens with keystone

Registered by Sam Yaple on 2015-08-29

Fernet tokens have a large advantage over UUID in terms of token generation. They are virtually instantly generated. Validation is the same speed, if not just a bit slower. However, this prevents needing to store tokens in the database (and clean tokens out of the database) resulting in a huge net gain for performance in a lot of ways.

I recommend we use it as the default token driver for Mitaka

Whiteboard

seems a little late to change all token generation in kolla to something that isn't really proven tech in a RC. --sdake

Agreed, I don't remember exactly what I was thinking, but I am almost positive I meant the default token driver for Mitaka, not Liberty. I just wanted it included in Liberty. Either way that is what it says now. --SamYaple

It would be great if we can jam this into Mitaka - although I know everyone is overloaded and the request is coming late. --sdake

This blueprint is far from complete given the TODO items in the work items, so bouncing to newton 1. --sdake

moving to newton-3 expected to be released on 2016-09-02. Please try to finish it before that otherwise it will be moved to Octata. - coolsvap
