我在IIS 7.5中使用.NET 2.0运行时有一个简单的.net应用程序,我在web.config中更改了机器密钥以使用以下内容：
<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="SHA1"/>
这在本地工作正常,但当我发布到服务器时,我得到一个“HttpException(0x80004005)：无法验证数据”每当浏览网站时.我已确保设置编译debug =“false”.将验证方法设置为3DES可以消除此问题,但我们需要使用SHA1.我在这里缺少一些配置选项吗？看下面的堆栈跟踪.

解决方法
您是否在真正的.NET 2.0应用程序池中运行该应用程序？ (我问,因为你使用的是IIS 7.5).
如果没有,请记住.NET 4.5框架中的加密算法已发生变化.
如果你需要兼容< .NET 4.5 Framework您需要一个兼容性标记：
<machineKey compatibilityMode="Framework20SP1" />
