我的 C# .net 应用程序正在使用 HTTPS Web 服务。由于证书现在即将到期，我正在尝试使用我已获得的新证书（我已使用 javasdks 的 keytool 转换为 .p12 的 .jks 文件）对其进行更新。我认为这很容易，因为我知道该怎么做，但它就是不合作。
到目前为止我所做的：
- 将证书导入到 CURRENT_USER\Personal
- 将证书导入到 LOCAL_MACHINE\Personal
- 给定正确的用户（apppoolidentity）通过 winhttpcertcfg 工具访问证书的私钥。下面是证书的权限列表。
使用 findprivatekey 工具，我还找到了实际的密钥文件，并赋予 apppoolidentity 对其的访问权限。（绝望中）。
C:\Program Files (x86)\Windows Resource Kits\Tools>winhttpcertcfg -l -c LOCAL_MACHINE\My -s "9000 - Blabla" Microsoft (R) WinHTTP 证书配置工具 版权所有 (C) Microsoft Corporation 2001。
匹配证书：CN=9000 - Blabla C=NO L="c/o Blabla AS, Blablaaddress" OU=957839827 OID.1.2.240.111111.1.9.8=12345678 OID.1.2.240.111111.1.9.2=Blabla Test O= BlaBla AS OU=多重允许
可以访问私钥的其他帐户和组包括： BUILTIN\Administrators NT AUTHORITY\SYSTEM IIS APPPOOL\ASP.NET v4.0 BUILTIN\Users NT AUTHORITY\NETWORK SERVICE DIGITROLLDMZ\IIS_WPG
我正在访问的网址如下所示：
https://test.blabla.com/blabla-5.0/services/Blabla?wsdl
...如果我从服务器的网络浏览器访问它，我可以选择证书，我选择新的，它说没关系，绿色和 SSL 按顺序排列，但我的应用程序代码看起来像这样：
public static blabla.service.NettforhandlerService getNettforhandlerService(string applicationPath)
{
blabla.service.NettforhandlerService service = new blabla.service.NettforhandlerService();
if (System.Configuration.ConfigurationManager.AppSettings["CertificateSerialNumber"] != null && System.Configuration.ConfigurationManager.AppSettings["CertificateSerialNumber"].Length > 0)
{
string serviceurl = service.Url;
X509Store store = new X509Store(StoreName.Root, StoreLocation.LocalMachine);
store.Open(OpenFlags.ReadOnly);
X509Certificate2Collection col = store.Certificates.Find(X509FindType.FindBySerialNumber, System.Configuration.ConfigurationManager.AppSettings["CertificateSerialNumber"], true);
ServicePointManager.Expect100Continue = true;
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
ServicePointManager.CertificatePolicy = new TrustHBSCertificatePolicy();
service.ClientCertificates.Add(col[0]);
}
return service;
}
仅输出此错误：
The request was aborted: Could not create SSL/TLS secure channel.
...我在 web.config 中添加了一些跟踪/调试信息，我从错误中发现的是：

我知道这看起来像正确的用户/身份没有被授予对证书的访问权限（来自 winhttpcertcfg），但我很确定它有，这就是我在这里不知所措的原因，
希望有一些严肃的https-certificate/web-service -skills的人可以在这里帮助我:-)
谢谢。
问候， Jørgen E.
