ListKeyPolicies 搭配 AWS SDK或 使用 CLI

取得金鑰的KMS金鑰政策名稱

下列list-key-policies範例會取得範例帳戶和區域中客戶受管金鑰之金鑰政策的名稱。您可以使用此命令來尋找 AWS 受管金鑰和客戶受管金鑰的金鑰政策名稱。

由於唯一有效的金鑰政策名稱是 default，因此此命令沒有用。

若要指定KMS金鑰，請使用 key-id 參數。此範例使用金鑰 ID 值，但您可以在此命令ARN中使用金鑰 ID 或金鑰。

aws kms list-key-policies \
    --key-id 1234abcd-12ab-34cd-56ef-1234567890ab

輸出：

{
    "PolicyNames": [
    "default"
    ]
}
