Chapter Five: Managing Your Keys
The XID is your identity online; if you lose your XID, the identity is gone. That means that it's very important to protect your XID, and that means protecting the keys that control your XID.
This chapter addresses that problem by demonstrating how to create a less vulnerable copy of your XID with less powerful keys and then how to properly archive your more most powerful keys. It also more generally discusses how to manage keys in your XID through additions, removals, and updates.
