Backing up your keys

You can move your key pair to a secure location with:

$ gpg --output rpm-feed.pub --armor --export <key id>
$ gpg --output rpm-feed.sec --armor --export-secret-key <key id>  

Copy them securely to a new location and import them with:

$ gpg --import  rpm-feed.pub
$ gpg --allow-secret-key-import --import  rpm-feed.sec
