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...

set -g status-keys vi
set -g history-limit 10000

  # Use: it { should accept_nested_attributes_for(:association_name).and_accept({valid_values => true}).but_reject({ :reject_if_nil => nil })}
  RSpec::Matchers.define :accept_nested_attributes_for do |association|
    match do |model|
      @model = model
      @nested_att_present = model.respond_to?("#{association}_attributes=".to_sym)
      if @nested_att_present && @reject
        model.send("#{association}_attributes=".to_sym,[@reject])
        @reject_success = model.send("#{association}").empty?
      end
      model.send("#{association}").clear
