.NET Core X509Certificate2用法(在Windows/IIS、Docker、Linux下)

monty • 5 年前 • 1147 次点击  

我很长时间都在尝试在.NET核心API中使用证书。

基本上,我需要使用它们的地方是运行在IIS和Docker上的.NET核心Web API。

我需要使用的证书用于:

Microsoft.AspNetCore.DataProtection 

public void ConfigureServices(IServiceCollection services)
{
  services.AddDataProtection()
    .PersistKeysToFileSystem(new DirectoryInfo(dataProtectionKeystorePath))
    .ProtectKeysWithCertificate
    (
      new X509Certificate2(dataProtectionCertificatePath, dataProtectionCertificateSecret)
    );
}

Kestrel Options to set SSL certificate 

public static IWebHost BuildWebHost(string[] args) =>
  WebHost.CreateDefaultBuilder(args)
    .UseKestrel
    (
      options =>
        {
          options.Listen(address, port, listenOptions =>
            {
              listenOptions.UseHttps(new X509Certificate2(sslCertificatePath, sslCertifciateSecret));
            }
          );
        }
      )
      // other setup
     ;

IdentityServer4.SigningCredentials

注意:此代码适用于从VS2017开始的开发计算机,但会在Windows 2008 R2 IIS测试服务器上引发这些异常。 

services.AddIdentityServer()
  .AddSigningCredential
  (
    new X509Certificate2(tokenCertificatePath, tokenCertificatePassphrase)
  )
  // other setup
  ;

这三种方法都意味着放置一个证书文件,使用构造函数加载它,传递秘密,然后开始。

Sarkasm>祝我快乐,这太简单了。萨克斯姆

所以我创建了一个持有证书的certs subdir。为机密添加了设置。已验证是否按预期加载/创建了所有值。已确认文件位于预期位置,因此存在。简言之如下: 

string dataProtectionKeystorePath = System.Path.Combine(Environment.ContentRootPath, "keystore");
string dataProtectionCertificatePath = System.Path.Combine(Environment.ContentRootPath, "certs", "keystore.pfx");
string dataProtectionSecret = Configuration.GetSection("CertificateSecrets").GetValue<string>("keystoreSecret", null);

string tokenCertificatePath = System.Path.Combine(Environment.ContentRootPath, "certs", "token.pfx");
string tokenCertificateSecret = Configuration.GetSection("CertificateSecrets").GetValue<string>("tokenSecret", null);

string sslCertificatePath = System.Path.Combine(Environment.ContentRootPath, "certs", "ssl.pfx");
string sslCertificateSecret = Configuration.GetSection("CertificateSecrets").GetValue<string>("tokenSecret", null);

让我们玩得开心他们说。所以我们去部署。

我最终得到的是那些例外:

数据保护异常:

几个月来,我一直面临着证书的异常,经常在谷歌上搜索,无论我尝试了什么(根据google的结果,github上的问题等等),我都会想起我错过了一些重要的东西。

我试图使用StorageFlags,但没有发现一个(组合)有效。

这些项目应该运行在windows(iis)、docker上,也许还可以运行一次linux(ubuntu、debian)。所以我们决定把证书放在一个(跨多个实例挂载的)子目录中。因此,我发现的建议将证书安装到Microsoft证书存储中的帖子将不起作用。怎么会在Docker和Linux上呢?

由于我倾向于使用的所有证书都受到了影响,我意识到问题可能是我对如何使用证书有重大的误解。

有谁能帮我弄清楚我漏掉的重点,并最终让证书运行吗?我需要配置什么吗?如果是这样的话?

只是一些调查总结:

我确定这些文件存在吗:是,否则会出现异常 

System.Security.Cryptography.CryptographicException: System cannot find specified file.

我确定密码是正确的吗:是,否则会出现异常 

Internal.Cryptography.CryptoThrowHelper+WindowsCryptographicException: The specified network password is not correct.

文件权限:感谢Cheshirecat提醒我。在Windows Server 2008 R2 IIS 7.5上,我检查了用户DefaultAppPool对certs subdir的文件权限(原以为现在是另一个用户unitl)。已向用户授予对certs subdir的完全访问文件权限 默认应用程序池 like shown in this link .

通常,IS4签名凭据异常在应用程序启动时发生。使用x509keystarageflags.machinekeyset不会在启动时引发,而是显示登录窗口并在登录后引发。不会返回任何令牌,但会创建会话,以便用户可以修改ASP NET标识帐户设置。

证书过期:证书可以过期。数据保护似乎没有检查过期日期,因此即使证书过期也可以使用。仍然可以使用Identity Server 4签名凭据,但如果Certificate过期,则ASP.NET核心令牌验证将引发未授权。

问题解决方案

一年半之后,解决方案是:一个不知何故损坏的(自签名/自创建)证书。

如果可以使用此代码检查证书是否有效: 

  static void Main(string[] args)
  {
    X509Certificate2 cert = new X509Certificate2(Path.Combine(Directory.GetCurrentDirectory(), "cert.pfx"), "password");
    Console.WriteLine("cert private key: " + cert.PrivateKey);
  }

如果您看到下面的输出,则证书是正确的,否则您将获得上述异常。 

cert private key: System.Security.Cryptography.RSACng

为开发创建证书

SSL证书

使用dotnet工具dev certs。此调用打开一个提示,然后将localhost ssl证书导入到currentuser证书存储( view it with MMC )程序中不需要更改代码。 

dotnet dev-certs https --trust
其他认证机构

“坏”证书被创建 using makecert . 我换成了 OpenSSL 但也可能是 New-SelfSignedCertificate 使用的工具(如果您使用的是Win 10)。

如果openssl安装正确并添加到path变量中,则以下批处理文件将创建工作证书(需要用户交互!). 

  openssl genrsa 2048 > private.pem
  openssl req -x509 -days 365 -new -key private.pem -out public.pem
  openssl pkcs12 -export -in public.pem -inkey private.pem -out cert.pfx
  REM openssl pkcs12 -info -in cert.pfx
  certutil -dump cert.pfx
  PAUSE

本地开发的设置(Win 7,vs 2017,IIS Express/Kestrel)

正如柴郡猫(再次感谢您)所描述的那样,所有部件工作的代码都符合.NET Core2.1的预期。包括数据保护和Identity Server 4签名凭据。

在Windows 2008 R2上部署到IIS 7.5

乐趣还在继续。使证书在本地开发计算机上工作并将其部署到IIS会引发“新”异常。

  • 已检查IIS上的文件权限(DefaultAppPool具有完全权限)
  • 证书与在本地计算机上工作的证书相同
  • 未安装使用的证书(不在开发计算机上,不在IIS计算机上),因此应获取实际文件。

日志显示了基本良好的设置

参考行57是: 

  cert = new X509Certificate2(certPath, certPassphrase);

对于Identity Server 4签名凭据也会发生相同的异常。

再次悬赏100美元获得答案,以帮助我在Windows Server 2008 R2上的IIS上运行此功能。

IIS和Docker解决方案(以及本地开发):使用此解决方案,IIS和Docker安装程序都不会抱怨: 

cert = new X509Certificate2(certPath, certPassphrase, X509KeyStorageFlags.MachineKeySet);
