Good question. Whenever I create keys, I back up the SQL I use to create them. This way I know how to recreate it exactly the way it was created in the first place. Of course, that brings up the point of what to do with the plain text to create the keys, but that's another discussion.
Really this code becomes a password, and needs to be secured as such. It also complicates deployments, but that's another discussion.
