将证书注册到SSL端口

Rob*_*etz 7 .net c# self-hosting .net-4.5 owin

我有一个Windows服务(作为LocalSystem运行),它自我托管OWIN服务(SignalR),需要通过SSL访问.

我可以在我的本地开发机器上设置SSL绑定 - 我可以在同一台机器上通过SSL访问我的服务.但是,当我转到另一台机器并尝试运行以下命令时,我收到一个错误:

命令:

netsh http add sslcert ipport=0.0.0.0:9389 appid={...guid here...} certhash=...cert hash here...

错误:

SSL证书添加失败,错误:1312

指定的登录会话不存在.它可能已被终止.

我使用的证书是完全签名的证书(不是开发证书),可以在我的本地开发箱中使用.这就是我在做的事情:

Windows服务启动并使用以下代码注册我的证书:

var store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
var path = AppDomain.CurrentDomain.BaseDirectory;
var cert = new X509Certificate2(path + @"\mycert.cer");
var existingCert = store.Certificates.Find(X509FindType.FindByThumbprint, cert.Thumbprint, false);
if (existingCert.Count == 0)
    store.Add(cert);
store.Close();

然后我尝试使用netsh和以下代码将证书绑定到端口9389:

var process = new Process {
    StartInfo = new ProcessStartInfo {
        WindowStyle = ProcessWindowStyle.Hidden,
        FileName = "cmd.exe",
        Arguments = "/c netsh http add sslcert ipport=0.0.0.0:9389 appid={12345678-db90-4b66-8b01-88f7af2e36bf} certhash=" + cert.thumbprint
    }
};
process.Start();

上面的代码成功将证书安装到"本地计算机 - 证书\受信任的根证书颁发机构\证书"证书文件夹 - 但netsh命令无法运行上面描述的错误.如果我使用netsh命令并在命令提示符下以管理员身份在该框中运行它也会抛出相同的错误 - 所以我不相信这是与代码相关的问题......

我不得不想象这有可能实现 - 许多其他应用程序创建自托管服务并通过ssl托管它们 - 但我似乎无法让它工作......任何人都有任何建议吗?也许是netsh的程序化替代品?

好吧,我找到了答案:

如果要从另一台计算机上引入证书,则该证书将无法在新计算机上使用。您必须在新计算机上创建一个自签名证书,并将其导入到本地计算机的受信任的根证书中。

答案来自这里:如何使用C#创建自签名证书?

为了后代的缘故,这是用于创建自签名证书的过程(来自以上引用的答案):

从项目参考中的“ COM”选项卡导入CertEnroll 1.0类型库

将以下方法添加到您的代码中:

对于任何其他阅读此答案的人-从原始问题导入证书的代码现在应更改为以下内容:

var certName = "Your Cert Subject Name";
var store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadWrite);
var existingCert = store.Certificates.Find(X509FindType.FindBySubjectName, certName, false);
if (existingCert.Count == 0)
{
    var cert = CreateSelfSignedCertificate(certName);
    store.Add(cert);
    RegisterCertForSSL(cert.Thumbprint);
}
store.Close();

  • 什么是“ RegisterCertForSSL”‽ (7认同)
  • @RobertPetz问题是“ [如何]将证书注册到SSL端口?”。这个答案没有告诉我的一件事是**如何将证书注册到SSL端口**因此,它没有回答问题。 (3认同)
  • 我走了那条路,它绝对可以工作-但是,当您运行installshield并尝试执行certutil时,您会遇到许多权限问题...下一个最好的事情是让C#应用程序从Windows服务中执行certutil在LocalSystem下运行,但老实说我更喜欢这种方式,因为它更容易调试 (2认同)
  • 这个答案实际上并没有回答问题。它讨论了如何创建证书(这不是问题的一部分),然后没有讨论如何将证书实际绑定到端口(问题所在)。认真地说,什么是RegisterCertForSSL(cert.Thumbprint)?它是某种框架方法吗?它是否包含在第三方组件中?你写了吗?如果是,那是如何工作的? (2认同)

这是完整的代码,包括:

  • 生成证书
  • 在端口上注册 ssl
  • 在该端口上运行简单的 HTTPS 服务器

** 请原谅我的代码质量。这只是我在网上找到的不同代码段粘在一起的非常脏的概念证明,Robert Petz 回答。我没有时间清理它:
