                How to export and import gpg keys
              
          
    Every so often I have to restore my gpg keys and I'm never sure how best to do it.  So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.
Method 1

Gotten from the RedHat GPG migration manual
Backup the public and secret keyrings and trust database

## Export all public keys

gpg -a --export >mypubkeys.asc
