# 1) Create your private key (any password will do, we remove it below)

$ cd ~/.ssh
$ openssl genrsa -des3 -out server.orig.key 2048


# 2) Remove the password

$ openssl rsa -in server.orig.key -out server.key

First of all, please note that token expiration and revoking are two different things.

1. Expiration only happens for web apps, not for native mobile apps, because native apps never expire.
2. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

1. How to hadle JWT expiration

A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data.

Quoted from JWT RFC:

   Overall thoughts: Ember.Component needs a section in the module doc block outlining the order of events (just like the 1.13 blog post).
   Individual events can then refer back to that lifecycle chart to avoid the "runs xth during re-renders but only on thursdays" sentences.
   The module doc block should also get the section on what triggers a re-render (from the 1.13 blog post).
