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 2016IIS 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。
