最近、「chmod」が「777」以外のいくつかのパラメータを受け入れていることに気づき、署名ファイルを自動電子メールハンドラに送信しようとしています。両端でgpgを使用すると簡単になりますが、受信機の公開鍵をどこに置くべきかわかりません。
契約当事者は、自分の検索戦略と自分自身を次のように説明します。

受信者は公開鍵情報をどこで見つけるべきですか？ありがとうございます。
ベストアンサー1
これは完全に役に立つ答えではありませんが、署名を確認して公開鍵をコピーしたい場合に便利です。
GNUプライバシーマニュアルプログラムはうまくいき、
これの出力をコピーします。
$ gpg --armor --export
次に、上記の出力を保存したファイルから取得します。
$gpg --import keyfile
