asp.net-core - Windows加密异常: Keyset does not exist

Question

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 在本地主机上运行的 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。

通常这意味着交换代码，例如

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 博客 https://benjii.me/2017/06/creating-self-signed-certificate-identity-server-azure/ 上的步骤创建的。

将证书和私钥导出到 PFX 文件，以便将公钥和私钥都包含在该文件中。

PFX 文件加载成功。加载代码为

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

Pfx 文件位于 Web 项目内，可在 X509Certificate 对象中找到并读入。

在 Visual Studio 中检查 X509Certificate2 时，属性 HasPrivateKey 返回 true，但 PrivateKey 属性在观察器中解析为异常。

'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上的立即窗口方法中执行 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

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

我尝试加载具有不同 X509KeyStorageFlags 设置的 pfx 文件，但行为和异常是相同的。

我还尝试将 PFX 安装到 Windows 计算机的证书管理器中，并且我成功地从那里加载了它，但抛出了相同的异常。

最后，当从 IdentityServer 请求访问 token 时，会抛出相同的异常。我已将异常跟踪粘贴在下面。

Answer 1

通过添加 IIS_IUSR 组解决了该问题。从这个链接Add group IIS_IUSR :

问题是 Windows 证书存储中证书的私钥的权限没有将 IIS_IUSRS 组设置为允许读取访问。

右键单击证书 -> 所有任务 -> 管理私钥 -> 添加组“IIS_IUSRS”
