Backup your OpenPGP key on paper using paperkey

If you are worried about your hard drive one day crashing and you losing access to your OpenPGP key (and thus the contents of your encrypted e-mails) then you should have been using a backup! That said an extra archival method of storing your key completely offline would be to use a program called paperkey to export the contents of your OpenPGP key to an easily printed file that you can then re-type into your PC if necessary.
