c#-4.0 - 获取上传到 Azure 存储的可用证书

Question

当我使用 rest-api 创建 VM 时，我想在 azure 中获取所有上传的证书以使用这些与 VM 关联的证书。

有必要，证书应该在本地机器上可用吗？如果是，当网站/门户在任何机器上打开时，有没有办法在本地安装证书。

您需要在每台使用 REST api 的机器上安装证书才能运行。

私钥和公钥的重点是维护安全性。我认为这不是您想要放在网站上供任何人安装的东西。

话虽如此，如果您通过网站进行 REST 调用，那么只有托管应用程序的服务器需要安装证书。

我构建了一个包含 REST URL 的 webrequest，就像这个一样，然后构建响应。

private HttpWebResponse CallAzure(HttpWebRequest request, string postData)
        {
            var certificateStore = new X509Store(StoreName.My, StoreLocation.CurrentUser);
            certificateStore.Open(OpenFlags.ReadOnly);
            var certs = certificateStore.Certificates.Find(X509FindType.FindByThumbprint, CertificateThumbprint, false);

            if (request.Method.ToUpper() == "POST")
            {
                var xDoc = new XmlDocument();
                xDoc.LoadXml(postData);

                var requestStream = request.GetRequestStream();
                var streamWriter = new StreamWriter(requestStream, Encoding.UTF8);
                xDoc.Save(streamWriter);

                streamWriter.Close();
                requestStream.Close();
            }
            request.ClientCertificates.Add(certs[0]);
            request.ContentType = "application/xml";
            request.Headers.Add("x-ms-version", "2012-03-01");

            ServicePointManager.Expect100Continue = false;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3;
            request.ServicePoint.Expect100Continue = false;
            var response = request.GetResponse();
            return (HttpWebResponse)response;
        }

我发现通过 PowerShell 安装证书最容易。

如果您想在这里生成自己的发布设置文件，这是一个非常简单的应用程序。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Security.Cryptography.X509Certificates;
using System.IO;

namespace CreatePublishSettingsFile
{
    class Program
    {
        private static string subscriptionId = "[your subscription id]";
        private static string subscriptionName = "My Awesome Subscription";
        private static string certificateThumbprint = "[certificate thumbprint. the certificate must have private key]";
        private static StoreLocation certificateStoreLocation = StoreLocation.CurrentUser;
        private static StoreName certificateStoreName = StoreName.My;
        private static string publishFileFormat = @"<?xml version=""1.0"" encoding=""utf-8""?>
<PublishData>
  <PublishProfile
    PublishMethod=""AzureServiceManagementAPI""
    Url=""https://management.core.windows.net/""
    ManagementCertificate=""{0}"">
    <Subscription
      Id=""{1}""
      Name=""{2}"" />
  </PublishProfile>
</PublishData>";

        static void Main(string[] args)
        {
            X509Store certificateStore = new X509Store(certificateStoreName, certificateStoreLocation);
            certificateStore.Open(OpenFlags.ReadOnly);
            X509Certificate2Collection certificates = certificateStore.Certificates;
            var matchingCertificates = certificates.Find(X509FindType.FindByThumbprint, certificateThumbprint, false);
            if (matchingCertificates.Count == 0)
            {
                Console.WriteLine("No matching certificate found. Please ensure that proper values are specified for Certificate Store Name, Location and Thumbprint");
            }
            else
            {
                var certificate = matchingCertificates[0];
                certificateData = Convert.ToBase64String(certificate.Export(X509ContentType.Pkcs12, string.Empty));
                if (string.IsNullOrWhiteSpace(subscriptionName))
                {
                    subscriptionName = subscriptionId;
                }
                string publishSettingsFileData = string.Format(publishFileFormat, certificateData, subscriptionId, subscriptionName);
                string fileName = Path.GetTempPath() + subscriptionId + ".publishsettings";
                File.WriteAllBytes(fileName, Encoding.UTF8.GetBytes(publishSettingsFileData));
                Console.WriteLine("Publish settings file written successfully at: " + fileName);
            }
            Console.WriteLine("Press any key to terminate the program.");
            Console.ReadLine();
        }
    }
}
