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。
