AWS KMS 使用 AWS SDKs程式碼範例
下列程式碼範例示範如何 AWS KMS 搭配 AWS 軟體開發套件 (SDK) 使用 。
基本概念是程式碼範例，這些範例說明如何在服務內執行基本操作。
Actions 是大型程式的程式碼摘錄，必須在內容中執行。雖然動作會告訴您如何呼叫個別服務函數，但您可以在其相關情境中查看內容中的動作。
案例是向您展示如何呼叫服務中的多個函數或與其他 AWS 服務組合來完成特定任務的程式碼範例。
如需 AWS SDK 開發人員指南和程式碼範例的完整清單，請參閱 搭配 AWS SDK 使用此服務。此主題也包含入門相關資訊和舊版 SDK 的詳細資訊。
開始使用

* results as they become available. By subscribing to the stream, we can process
* each page of results as they are emitted.
