您可以使用自己的加密金鑰來加密貴機構的資料，而非使用 Google Workspace 提供的加密功能。如果使用 Google Workspace 用戶端加密 (CSE) 功能，系統會先在用戶端的瀏覽器中加密檔案，再將檔案儲存在雲端硬碟的雲端儲存空間。這麼一來，Google 伺服器就無法存取您的加密金鑰，也無法解密資料。詳情請參閱「關於用戶端加密」。
透過這項 API，您可以透過自訂外部金鑰服務，控管用於保護資料的頂層加密金鑰。使用這個 API 建立外部金鑰服務後，Google Workspace 管理員就能連線至該服務，並為使用者啟用 CSE。

This is achieved by using your own external Key Access Control List Service (KACLS). Google Workspace generates a Data Encryption Key (DEK) and sends it to your KACLS for encryption with a Key Encryption Key (KEK). Your service then returns the encrypted DEK to Google Workspace. This ensures that only users with KACLS access can decrypt the stored data.\n"]]
