這個 PowerShell 腳本的用途是自動化更新 IIS 網站的 SSL 憑證。主要功能包括:
1. 下載和讀取 PFX 憑證密碼:
o 從指定的 URL 下載 PFX 憑證的密碼。
2. 下載 PFX 憑證檔案:
o 從指定的 URL 下載 PFX 憑證檔案到本地。
3. 匯入憑證並取得指紋:
o 將 PFX 憑證匯入到本地機器的證書存儲區,並取得匯入憑證的指紋。
4. 獲取所有 IIS 網站名稱和目前 SSL 綁定資訊:
o 獲取所有 IIS 網站名稱,並顯示每個網站當前的 SSL 綁定資訊和憑證指紋。
5. 更新 SSL 綁定:
o 使用新憑證的指紋更新所有使用舊憑證的 SSL 綁定。
6. 檢查 SSL 綁定是否已切換到新憑證:
o 驗證所有網站的 SSL 綁定是否已更新到新的憑證指紋。
7. 刪除本地的 PFX 檔案:
o 刪除下載的臨時 PFX 檔案。
8. 刪除舊憑證:
o 刪除與新憑證不同的舊憑證,以確保只保留最新的憑證。
9. 重新啟動 IIS 服務:
o 重新啟動 IIS 服務以應用新的憑證設定。
10. 刪除腳本本身:
o 在操作完成後刪除腳本本身。
這個腳本實現了自動化的 SSL 憑證更新流程,適用於需要定期更新憑證的 IIS 伺服器環境。
