+## cl.security.1 对API9中已经抛出的异常，补写throws标签
+对于在API9中已经抛出异常而JS DOC中漏写throws标签的接口，在since 9的注释中补上throws标签。
+
+**变更影响**
+
+对于已发布的JS接口，可能影响异常处理流程，包括同步异常和异步异常。应用需要根据最新的throws标签，排查是否有遗漏的异常处理流程，结合实际情况进行适配。

+
+**适配指导**
+
+由于漏标的throws异常发生在较少见的情况下，应用可以结合实际情况，排查漏标的throws标签是否需要专门适配。
+
+- 对于同步方法，如createSign等，请使用try/catch方式处理错误信息。
+
+- 对于异步方法，如convertKey等，请使用try/catch方式处理同步的参数错误，使用error对象的方式获取异步的参数错误和业务执行错误。
