Let's Encrypt のドメイン名の所有確認方法

  • http-01チャレンジ

Let's Encrypt サーバからトークンを取得し、このトークンを含むファイルを対象ドメイン名の web サーバ上の特定のディレクトリに置くことでドメイン名の所有確認を行います。
たとえば「example.com」の証明書を発行する場合、http://example.com/.well-known/acme-challenge/(取得したトークン)という URL にファイルを設置する必要があります。

  • dns-01チャレンジ

Let's Encrypt サーバから取得したトークンを、対象ドメイン名の権威 DNS サーバに登録することで所有確認を行います。
たとえば「example.com」の証明書を発行する場合、DNS サーバに_acme-challenge.example.com. IN TXT "(取得したトークンを元に生成したハッシュ値)"というレコードを設定します。

以上。
