+WindowsサーバのIISにLet's Encryptで取得したワイルドカードSSL証明書をインポートする方法を調べたのでまとめした。
+
+## 環境
+
+- `Windows 2016`
+- `IIS 10`
+
+## 必要なもの
+いろいろと試行錯誤したのですが、どうやらIISに対してSSL証明書を登録するためには、IISからCSRを作成する必要があるようです。しかし、Let's Encryptを用いてSSL証明書を取得する場合、どのようなCSRで証明書を取得しているのかわかりません。その結果、IISにSSL証明書を登録することができません。
+
+この問題を解決するために、[PKISharp/win\-acme](https://github.com/PKISharp/win-acme)を利用します。このツールを利用することで、IISに自動的にLet's Encryptから取得したSSL証明書を登録することができます。
+
+## 操作ログ
+[PKISharp/win\-acme](https://github.com/PKISharp/win-acme)をダウンロード後、以下のように操作することでワイルドカードSSL証明書をIISに登録できました。
+
+なお、手動でDNSに`txt`レコードを登録、削除を間に挟んでいることに注意ください。
