标签: c# ssl private-key x509certificate2

我已使用私钥在本地计算机商店(win7)上安装了证书。 在c#代码中我这样做:

        X509Certificate2 cert = null;
        var store = new X509Store(storeName, storeLocation);
        store.Open(OpenFlags.ReadOnly);
        try
        {
            var result = store.Certificates.Find(X509FindType.FindByThumbprint, thumbprint, false);
            ServicePointManager.Expect100Continue = true;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
            ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
            cert = result.Count > 0 
                ? result[0] 
                : null;
        }
        finally
        {
            store.Close();
        }
        return cert;

cert 变量中,我有我的证书但是它有问题:HasPrivateKey为true但是PrivateKey没有任何对象。如果我使用我的Web应用程序的C#代码中的REST请求发送它,我有错误:

AcquireCredentialsHandle() failed with error 0X8009030D.
The request was aborted: Could not create SSL/TLS secure channel.

商店内的证书授予所有权利。请帮忙,出了什么问题?

Certutil导致俄语(我隐藏安全信息" ***"):

我发现了这个问题。我从机器商店删除了证书,然后将安装的证书从当前用户商店导出到.pfx文件,并将其导入机器商店。现在PrivateKey有了对象。 接下来,我将协议类型从Tls更改为Tls12(适用于Win7 +):

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
