I'm reading up on these instructions for backing up gpg keys: https://gist.github.com/chrisroos/1205934
He says that in the gpg instructions it says that it's better to export trustdb and simply backing it up. However these instructions were created five years ago, so I'm wondering whether this is still necessary. Ideally I would just create a tar archive of the .gnupg directory containing:
- pubring.gpg
- secring.gpg
- trustdb.gpg
Thoughts?
TIA, Ole
