c# - 加密异常 : The data is invalid in MVC 4 with WIF enabled

我创建了一个 MVC 4 项目并将其设置为 Azure ACS。它与 System.Identity 一起工作。我将其更改为使用 Microsoft.Identity 来启用 WIF，我的配置文件现在如下所示:

我的问题是当我运行网站时，我得到:

   System.Security.Cryptography.ProtectedData.Unprotect(Byte[] encryptedData, Byte[] optionalEntropy, DataProtectionScope scope) +318
   Microsoft.IdentityModel.Web.ProtectedDataCookieTransform.Decode(Byte[] encoded) +203

[InvalidOperationException: ID1073: A CryptographicException occurred when attempting to decrypt the cookie using the ProtectedData API (see inner exception for details). If you are using IIS 7.5, this could be due to the loadUserProfile setting on the Application Pool being set to false. ]

最佳答案

WIF 中的默认保护是使用 DPAPI，如果未加载配置文件，它就会失败(通常在云托管中失败)。您可以使用 MachineKey 保护，而不是依赖于 ASP.NET 机器 key

http://leastprivilege.com/2012/07/12/machinekey-based-session-protection-for-wif/

另一方面，如果您使用的是内置的 NET 4.5 和 System.IdentityModel。您不再需要 WIF，并且机器 key 保护已经在核心组件中可用。此外，您必须引用 System.IdentityModel.Services dll(其中包含 http 模块)
