我可以用C#列出本地安装的数字证书吗？

Question

我一直在努力寻找获取当前安装在本地计算机上的数字证书信息的方法 - 任何可以获得X509Certificate2类集合的方法.

我能够找到这个问题,解释如何从.pfx文件中获取它.

知道如何为已安装的证书做到这一点吗？

作为入门者,您可以查看以下代码:

using System;
using System.Security.Cryptography.X509Certificates;

namespace Encryption
   {
   class CertificateTest
      {
      static void Main()
         {
         X509Store store = new X509Store(StoreName.Root,
            StoreLocation.LocalMachine);
         store.Open(OpenFlags.ReadOnly);
         Console.WriteLine("Friendly Name\t\t\t\t\t Expiration date");
         foreach (X509Certificate2 certificate in store.Certificates)
            {
            Console.WriteLine("{0}\t{1}", certificate.FriendlyName,
               certificate.NotAfter);
            }
         store.Close();
         }
      }
   }

网上有更多高级样品.寻找System.Security.Cryptography.X509Certificates关键字.

以下代码列出了您自己的证书及其属性.

static void o(string s, params object[] args)
{
    Console.WriteLine(s, args);
}

static void CertList()
{
    X509Store store = new X509Store(StoreName.My,  StoreLocation.CurrentUser);
    store.Open(OpenFlags.ReadOnly);
    foreach (X509Certificate2 certificate in store.Certificates)
    {
        o("");
        o("Friendly Name: {0}", certificate.FriendlyName);
        o("Simple Name:   {0}", 
           certificate.GetNameInfo(X509NameType.SimpleName, true));
        o("Issuer:        {0}", certificate.Issuer);
        o("Expiration:    {0}", certificate.NotAfter);

        //  http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509keyusageextension.aspx
        foreach (X509Extension extension in certificate.Extensions)
        {
            o(" {0}  ({1})", extension.Oid.FriendlyName, extension.Oid.Value);

            if (extension.Oid.Value == "2.5.29.15")
            //  if (extension.Oid.FriendlyName == "Key Usage")
            {
                X509KeyUsageExtension ext = (X509KeyUsageExtension)extension;
                o("Key usages:          {0}", ext.KeyUsages);
            }
            else if (extension.Oid.Value == "2.5.29.37")
            //  if (extension.Oid.FriendlyName == "Extended Key Usage")
            {
                X509EnhancedKeyUsageExtension ext =
                                   (X509EnhancedKeyUsageExtension)extension;
                o("Extended Key usages: {0}", ext.EnhancedKeyUsages);
            }
        }
    }
    store.Close();
}
