在调试中进行加密操作时发生错误 [英] Error occurred during a cryptographic operation in debug
本文介绍了在调试中进行加密操作时发生错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我收到以下错误.这似乎只是在我将Visual Studio 2015升级到第一次更新后才开始的.我在这里读了一些线程，这是关于机器密钥的问题?我不确定如何修复它并防止它.当前，当我使用IIS Express在调试中运行此错误时，我在本地计算机上收到此错误.
I'm getting the below error. This seems to have only started after I upgraded my visual studio 2015 to have the first update. I have read a few threads here about this being an issue with the machine key? I'm not sure how to fix it though and prevent it. Currently I'm getting this error on my local machine when I run this in debug using IIS express.
异常详细信息:System.Security.Cryptography.CryptographicException:加密操作期间发生错误.
Cache = db.UserTokenCacheList.FirstOrDefault(c => c.webUserUniqueId == userId);
// place the entry in memory
this.Deserialize((Cache == null) ? null : MachineKey.Unprotect(Cache.cacheBits,"ADALCache"));

推荐答案
找到了解决方案.
错误来自的代码部分是AdalToken.Cache.cs文件.
The section of code the error was coming from is the AdalToken.Cache.cs file.
userId = signedInUserId;
this.AfterAccess = AfterAccessNotification;
this.BeforeAccess = BeforeAccessNotification;
this.BeforeWrite = BeforeWriteNotification;
// look up the entry in the database
Cache = db.UserTokenCacheList.FirstOrDefault(c => c.webUserUniqueId == userId);
// place the entry in memory
this.Deserialize((Cache == null) ? null : MachineKey.Unprotect(Cache.cacheBits,"ADALCache"));
特别是最后一行.
与db.UserTokenCacheList的上下文也相关:
Also relevant is the context for the db.UserTokenCacheList which is:
{
public class ApplicationDbContext : DbContext
{
public ApplicationDbContext()
: base("DefaultConnection")
{
}
public DbSet<UserTokenCache> UserTokenCacheList { get; set; }
}
public class UserTokenCache
{
[Key]
public int UserTokenCacheId { get; set; }
public string webUserUniqueId { get; set; }
public byte[] cacheBits { get; set; }
public DateTime LastWrite { get; set; }
}
}
所有这些都是由Visual Studio在启动此新项目时经历用于设置Azure身份验证的向导时生成的.
All of this was generated by visual studio when I went through the wizard for setting up Azure authentication when I started this new project.
关于ApplicationDbContext中的 base("DefaultConnection") .
Regarding the base("DefaultConnection") in the ApplicationDbContext.
在我的web.config中没有为此输入的条目，但是直到最近这一直有效.
There was no entry for this in my web.config, however up until recently this has always worked.
在web.config中的<connectionStrings>我为DefaultConnection添加了一行以指向我的数据库，现在，至少在目前，它可以正常工作.
In the web.config, within the < connectionStrings > I added a line for DefaultConnection to point at my database and now it all works, at least for now.
希望这对遇到相同错误的人有所帮助.
Hope this may be of help to anyone who gets the same error.
