WindowsCryptographicException：密钥集不存在答案

【问题标题】：WindowsCryptographicException: Keyset does not existWindowsCryptographicException：密钥集不存在

【问题描述】：

我想创建或获取证书、创建 pfx 文件、加载它并让 IdentityServer 使用它。但是，IdentityServer 无法使用我的 pfx。

如何成功创建 pfx 并让 IdentityServer 使用它？

我有一个使用 ASP.Net Core 在 localhost 上运行的 IdentityServer4 Web 解决方案。我正在准备在 Azure 上运行的生产解决方案，并将证书添加到 IdentityServer 管道，而不是开发人员签名证书。

通常这意味着像交换代码

services.AddIdentityServer()
        .AddDeveloperSigningCredential()

与

services.AddIdentityServer()
        .AddSigningCredential(cert)

其中“cert”是 X509Certificate2 的对象实例，它已加载包含证书（带有公钥和私钥）的 PFX 文件。

我使用的证书是自签名的，是按照 Ben Cull 的博客 https://benjii.me/2017/06/creating-self-signed-certificate-identity-server-azure/ 上的步骤创建的

证书和私钥被导出到 PFX 文件中，以便公钥和私钥都包含在文件中。

PFX 文件加载成功。加载代码是

cert = new X509Certificate2(Path.Combine(Environment.ContentRootPath, "MyPfxFile.pfx"), "password-used-when-exporting-pfx");

Pfx 文件位于 Web 项目中，可以找到并读入 X509Certificate 对象。

在 Visual Studio 中检查 X509Certificate2 时，属性 HasPrivateKey 返回 true，但 PrivateKey 属性解析为观察程序中的异常。

'cert.PrivateKey' threw an exception of type 'Internal.Cryptography.CryptoThrowHelper.WindowsCryptographicException'

所有其他属性在观察者中看起来都很好。

此外，当我在证书对象实例的即时窗口方法中执行 GetRSAPrivateKey 时，它会返回异常。

cert.GetRSAPrivateKey()
'cert.GetRSAPrivateKey()' threw an exception of type 'Internal.Cryptography.CryptoThrowHelper.WindowsCryptographicException'
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2146893798
    HelpLink: null
    InnerException: null
    Message: "Keyset as registered is invalid"

    TargetSite: {System.Security.Cryptography.SafeProvHandle CreateProvHandle(System.Security.Cryptography.CspParameters, Boolean)}

我尝试使用 X509KeyStorageFlags 的不同设置加载 pfx 文件，但行为和异常是相同的。

我也尝试将 PFX 安装到 Windows 机器的证书管理器中，并且我已成功从那里加载它，但抛出了相同的异常。

最后，当向 IdentityServer 请求访问令牌时，会抛出相同的异常。我在下面粘贴了异常跟踪。

【问题讨论】：

如果您已将其安装到证书存储中，您可以运行certutil -silent -store my 并共享证书的数据（我想知道的具体是“Provider”的值）。（certutil -user -silent -store my 如果它在 CurrentUser\My 而不是 LocalMachine\My 中）
@bartonjs 这里是输出：------------ 序列号：b3eeb248fd720d0e 发行者：CN=abaris.no NotBefore：16.10.2018 16:25 NotAfter：13.10 .2028 16:25 主题：CN=abaris.no 签名匹配公钥根证书：主题匹配颁发者证书哈希（sha1）：bb 1a b6 b9 f8 1b 27 07 93 92 64 bc c5 90 c3 43 d2 62 72 9c 密钥容器= {700D6BDE-4203-418B-A353-0BFEABAC26A7} Provider = Microsoft Enhanced Cryptographic Provider v1.0 Missing stored keyset 加密测试通过 -------------- 它还显示“缺少存储的密钥集”。 ....
好的，增强型提供程序肯定应该在 CNG 中加载，但本地方同意私钥文件丢失似乎是指示性的。当您将其添加到商店时，您可能没有设置 PersistKeySey 并且密钥已被删除。为了从字节加载它，必须进行某种密钥克隆，这会导致在加载之前删除密钥。如果您在使用 PersistKeySet 加载后重新导入商店，问题可能会消失。
@bartonjs 我为 X509KeyStorageFlags 使用了不同的设置，包括 PersistKeySet。当 Pfx 安装到 X509Store(StoreName.My, StoreLocation.CurrentUser) 时，我已验证私钥已写入磁盘，并且进程标识对文件夹和私钥文件具有读写访问权限。在 MMC 中安装 pfx 时，证书 UI 会显示“您有一个与此证书对应的私钥”。我没有按照你的建议尝试重新导入
@bartonjs 我已经使用 makecert 生成了另一个证书，并且该证书现在可以使用私钥成功加载，而无需更改源代码。因此，使用 OpenSSL 生成的证书和 pfx 似乎有些东西。我很高兴现在使用 makecert，即使它已被正式弃用。

通过添加 IIS_IUSR 组解决了该问题。从此链接Add group IIS_IUSR：

问题在于 Windows 证书存储中证书的私钥的权限没有设置 IIS_IUSRS 组以允许读取访问。

右键证书->所有任务->管理私钥->添加组“IIS_IUSRS”

【讨论】：

就我而言，我的Application Pool Identity 不是IIS_IUSR，但这个答案仍然解决了我的问题；将应用程序池的身份添加到私钥的权限中修复了它。谢谢！
此解决方案会有所不同，正如@codeMonkey 所指出的，它是不同的应用程序池标识。我的是一个完全不同的应用程序用户。检查您的应用了解更多详细信息 - 添加 iis_usr 可能不适合您。
将IIS_IUSRS 组添加到证书对我有用，即使我有不同的应用程序池标识。 +1
这个问题我们已经有好几个月了，现在解决了。谢谢大家。
@mihuilk 你是程序员中的神，谢谢！

我也关注了那篇博文，也遇到了这个问题。问题是当你运行它来创建 PKCS12 文件时：

openssl pkcs12 -export -out example.pfx -inkey example.key -in example.crt -certfile example.crt

尝试删除-certfile example.crt，它应该可以工作。

同样根据.NET Core X509Certificate2 usage (under Windows/IIS, Docker, Linux)，您可以通过访问cert.PrivateKey 来测试证书是否从文件中正确加载。例如

X509Certificate2 cert = new X509Certificate2(Path.Combine(Directory.GetCurrentDirectory(), "cert.pfx"), "password");
Console.WriteLine("cert private key: " + cert.PrivateKey);

【讨论】：

为什么会这样？删除 -certfile example.crt 解决了这个问题。但是好像没有最后一个命令创建的pfx更小，但是用最后一个命令，它不包含私钥？
我不是专家，但据我了解，-certfile file 选项允许添加证书链（除了输入证书之外，将该文件中的所有证书添加到 .p12 存储）

【解决方案3】：

在 IIS 10 上，我必须将我的应用程序池标识更改为 LocalSystem

【解决方案4】：

哦，嘿，这是我的博文！很高兴看到它......尽管人们遇到了问题，但希望能有所帮助。说到这里，我自己也遇到了这个异常！

我的问题是我创建了证书并尝试使用new X509Certificate2(path, password) 语法从磁盘加载它，但由于某种原因，我不得不将证书导入我的开发机器上的注册表中以阻止异常的发生。我真的不知道为什么。

确保将证书导入CurrentUser 注册表的My/Personal 存储区。

这个帖子有很多不同的答案，我希望其中一个对你有用，读者:)
