設定和監控目錄儲存貯體的預設加密

使用 AWS SDK for Java 2.x，您可以使用 AWS KMS key applyServerSideEncryptionByDefault方法請求 Amazon S3 使用 ，以指定 SSE-KMS 進行資料加密的目錄儲存貯體預設加密組態。您可以建立對稱加密 KMS 金鑰，並在請求中指定 。

使用 AWS SDK for .NET，您可以使用 AWS KMS key ServerSideEncryptionByDefault 屬性來指定目錄儲存貯體的預設加密組態，以使用 SSE-KMS 進行資料加密，以請求 Amazon S3 使用 。您可以建立對稱加密客戶受管金鑰，並在請求中指定 。
