将证书注册到SSL端口

本文关键字：SSL 端口注册证书 | 更新日期: 2023-09-27 18:27:54

我有一个windows服务（以LocalSystem运行），它自托管OWIN服务（SignalR），需要通过SSL访问。

我可以在本地开发机器上设置SSL绑定，而且我可以在同一台机器上通过SSL访问我的服务。然而，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。它可能已经被终止。

我使用的证书是一个完全签名的证书（而不是开发证书），可以在我的本地开发箱中使用。以下是我正在做的：

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();

上面的代码成功地将证书安装到"；本地机器-证书''受信任的根证书颁发机构''证书"；证书文件夹-但是netsh命令无法运行，并出现上面描述的错误。如果我使用netsh命令，并作为该框的管理员在命令提示符下运行它，它也会抛出相同的错误——所以我不认为这是与代码相关的问题。。。

我不得不想象这是可能实现的——许多其他应用程序创建自托管服务并通过ssl托管它们——但我似乎根本无法实现这一点。。。有人有什么建议吗？也许是netsh的程序化替代方案？

将证书注册到SSL端口

好的，我找到了答案：

如果您从另一台机器带来证书，它将无法在新机器上工作。您必须在新计算机上创建一个自签名证书，并将其导入本地计算机的受信任根证书。

答案就在这里：如何使用C#创建自签名证书？

为了子孙后代的利益，这是用于创建自签名证书的过程（根据上述答案）：

从项目参考中的COM选项卡导入CertEnroll 1.0类型库

将以下方法添加到代码中：

using CERTENROLLLib;
public static X509Certificate2 CreateSelfSignedCertificate(string subjectName)
{
    // create DN for subject and issuer
    var dn = new CX500DistinguishedName();
    dn.Encode("CN=" + subjectName, X500NameFlags.XCN_CERT_NAME_STR_NONE);
    // create a new private key for the certificate
    CX509PrivateKey privateKey = new CX509PrivateKey();
    privateKey.ProviderName = "Microsoft Base Cryptographic Provider v1.0";
    privateKey.MachineContext = true;
    privateKey.Length = 2048;
    privateKey.KeySpec = X509KeySpec.XCN_AT_SIGNATURE; // use is not limited
    privateKey.ExportPolicy = X509PrivateKeyExportFlags.XCN_NCRYPT_ALLOW_PLAINTEXT_EXPORT_FLAG;
    privateKey.Create();
    // Use the stronger SHA512 hashing algorithm
    var hashobj = new CObjectId();
    hashobj.InitializeFromAlgorithmName(ObjectIdGroupId.XCN_CRYPT_HASH_ALG_OID_GROUP_ID,
        ObjectIdPublicKeyFlags.XCN_CRYPT_OID_INFO_PUBKEY_ANY, 
        AlgorithmFlags.AlgorithmFlagsNone, "SHA512");
    // add extended key usage if you want - look at MSDN for a list of possible OIDs
    var oid = new CObjectId();
    oid.InitializeFromValue("1.3.6.1.5.5.7.3.1"); // SSL server
    var oidlist = new CObjectIds();
    oidlist.Add(oid);
    var eku = new CX509ExtensionEnhancedKeyUsage();
    eku.InitializeEncode(oidlist); 
    // Create the self signing request
    var cert = new CX509CertificateRequestCertificate();
    cert.InitializeFromPrivateKey(X509CertificateEnrollmentContext.ContextMachine, privateKey, "");
    cert.Subject = dn;
    cert.Issuer = dn; // the issuer and the subject are the same
    cert.NotBefore = DateTime.Now;
    // this cert expires immediately. Change to whatever makes sense for you
    cert.NotAfter = DateTime.Now; 
    cert.X509Extensions.Add((CX509Extension)eku); // add the EKU
    cert.HashAlgorithm = hashobj; // Specify the hashing algorithm
    cert.Encode(); // encode the certificate
    // Do the final enrollment process
    var enroll = new CX509Enrollment();
    enroll.InitializeFromRequest(cert); // load the certificate
    enroll.CertificateFriendlyName = subjectName; // Optional: add a friendly name
    string csr = enroll.CreateRequest(); // Output the request in base64
    // and install it back as the response
    enroll.InstallResponse(InstallResponseRestrictionFlags.AllowUntrustedCertificate,
        csr, EncodingType.XCN_CRYPT_STRING_BASE64, ""); // no password
    // output a base64 encoded PKCS#12 so we can import it back to the .Net security classes
    var base64encoded = enroll.CreatePFX("", // no password, this is for internal consumption
        PFXExportOptions.PFXExportChainWithRoot);
    // instantiate the target class with the PKCS#12 data (and the empty password)
    return new System.Security.Cryptography.X509Certificates.X509Certificate2(
        System.Convert.FromBase64String(base64encoded), "", 
        // mark the private key as exportable (this is usually what you want to do)
        System.Security.Cryptography.X509Certificates.X509KeyStorageFlags.Exportable
    );
}

对于阅读此答案的其他人来说，从原始问题导入证书的代码现在应该更改为以下内容：

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();

以下是完整的代码，包括：

在端口上注册ssl
在该端口上运行简单HTTPS服务器
