Microsoft Windows Rights Management 服务 (RMS），是一种与应用程序协作来保护数字内容（不论其何去何从）的安全技术，专为那些需要保护敏感的 Web 内容、文档和电子邮件的用户而设计。用户可以严格规定哪些用户可以打开、读取、修改和重新分发特定内容。组织可以创建权限策略模板，以实施用户应用于内容的策略。
下载并添加引用以下3个DLL：
Microsoft.Office.Interop.Excel.dll
Microsoft.Office.Interop.PowerPoint.dll
Microsoft.Office.Interop.Word.dll
并在dll的属性中，把“嵌入互操作类型”设为False
添加以下引用：
在添加引用-程序集-扩展中，引用office ,(或引用Microsoft Office 14.0 Object Library)
在添加引用-程序集-框架中，引用PresentationCore和PresentationFramework
打开word或者Excel等office文件，在信息-保护文档-限制访问-选择连接到权限管理服务器并获取模版，登陆域账号，后续在RMS加密工作将会使用这个域账号进行：
