                Instructions for exporting/importing (backup/restore) 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

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...
