GPG: Import and export instructions

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.

Export keys and ownertrust

gpg --export --armor 1E0B5331219BEA88 > 1E0B5331219BEA88.pub.asc
gpg --export-secret-keys --armor 1E0B5331219BEA88 > 1E0B5331219BEA88.priv.asc
gpg --export-secret-subkeys --armor 1E0B5331219BEA88 > 1E0B5331219BEA88.sub_priv.asc

gpg --export-ownertrust > ownertrust.txt

Here's how to test whether a parameter is unset, or empty ("Null") or set with a value:

+--------------------+----------------------+-----------------+-----------------+
|                    |       parameter      |     parameter   |    parameter    |
|                    |   Set and Not Null   |   Set But Null  |      Unset      |
+--------------------+----------------------+-----------------+-----------------+
| ${parameter:-word} | substitute parameter | substitute word | substitute word |
| ${parameter-word}  | substitute parameter | substitute null | substitute word |
| ${parameter:=word} | substitute parameter | assign word     | assign word     |
| ${parameter=word}  | substitute parameter | substitute null | assign word     |
