最初在Startup.cs
中,
我们完全省略了AddDataProtection()
调用。当我们尝试部署该应用程序时,我们看到了以下内容:
System.Security.Cryptography.CryptographicException: The key {...} was not found in the key ring.
at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.UnprotectCore(Byte[] protectedData, Boolean allowOperationsOnRevokedKeys, UnprotectStatus& status)
at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.DangerousUnprotect(Byte[] protectedData, Boolean ignoreRevocationErrors, Boolean& requiresMigration, Boolean& wasRevoked)
at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.Unprotect(Byte[] protectedData)
at Microsoft.AspNetCore.Session.CookieProtection.Unprotect(IDataProtector protector, String protectedText, ILogger logger)
warn: Microsoft.AspNetCore.Session.SessionMiddleware[7]
Error unprotecting the session cookie.
当我将services.AddData.AddDataProtection().SetApplicationName("MyAppName");
添加到ConfigureServices()
时,我们现在可以看到部署之后
System.Exception: An error was encountered while handling the remote login. ---> System.Exception: Correlation failed.
--- End of inner exception stack trace ---

at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.Invoke(HttpContext context)

at Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware.Invoke(HttpContext context)
warn: Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler[15]
'.AspNetCore.Correlation.OpenIdConnect.{SomeWeirdString}' cookie not found.
我在Google上搜索了很多,似乎解决此问题的“正确”方法是使用.PersistKeysToFileSystem()
合并加密密钥。但是有替代方法吗?例如完全禁用加密/数据保护?
在某些背景下,该应用程序是我们从ASP.NET迁移到ASP.NET Core的最后阶段,以前我们将会话状态存储在Redis中,没有进行加密。
答案 0 :(得分:0)
数据保护堆栈是必需的,用于保护cookie,会话状态,临时数据等数据。数据保护将密钥保留在某个地方以加密和解密数据。有几个选项可以保留键,默认情况下使用文件系统或注册表。在IIS或Azure中的本地服务器上托管时,它通常可以正常工作。对于其他部署选项,尤其是使用容器,通常必须执行一些配置。例如,容器通常具有临时存储,因此在部署新的容器实例后,加密密钥会丢失。
正如您提到的Redis一样,建议您研究一下Redis密钥存储提供程序:https://docs.microsoft.com/en-us/aspnet/core/security/data-protection/implementation/key-storage-providers?view=aspnetcore-2.2&tabs=visual-studio#azure-and-redis。
