The following code example demonstrates how to display user interface dialogs to select and view X.509 certificates.
using System; using System.Security.Cryptography; using System.Security.Permissions; using System.IO; using System.Security.Cryptography.X509Certificates; class CertSelect { static void Main() { try { X509Store store = new X509Store("MY",StoreLocation.CurrentUser); store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly); X509Certificate2Collection collection = (X509Certificate2Collection)store.Certificates; X509Certificate2Collection fcollection = (X509Certificate2Collection)collection.Find(X509FindType.FindByTimeValid,DateTime.Now,false); X509Certificate2Collection scollection = X509Certificate2UI.SelectFromCollection(fcollection, "Test Certificate Select","Select a certificate from the following list to get information on that certificate",X509SelectionFlag.MultiSelection); Console.WriteLine("Number of certificates: {0}{1}",scollection.Count,Environment.NewLine); foreach (X509Certificate2 x509 in scollection) { byte[] rawdata = x509.RawData; Console.WriteLine("Content Type: {0}{1}",X509Certificate2.GetCertContentType(rawdata),Environment.NewLine); Console.WriteLine("Friendly Name: {0}{1}",x509.FriendlyName,Environment.NewLine); Console.WriteLine("Certificate Verified?: {0}{1}",x509.Verify(),Environment.NewLine); Console.WriteLine("Simple Name: {0}{1}",x509.GetNameInfo(X509NameType.SimpleName,true),Environment.NewLine); Console.WriteLine("Signature Algorithm: {0}{1}",x509.SignatureAlgorithm.FriendlyName,Environment.NewLine); Console.WriteLine("Private Key: {0}{1}",x509.PrivateKey.ToXmlString(false),Environment.NewLine); Console.WriteLine("Public Key: {0}{1}",x509.PublicKey.Key.ToXmlString(false),Environment.NewLine); Console.WriteLine("Certificate Archived?: {0}{1}",x509.Archived,Environment.NewLine); Console.WriteLine("Length of Raw Data: {0}{1}",x509.RawData.Length,Environment.NewLine); X509Certificate2UI.DisplayCertificate(x509); x509.Reset(); } store.Close(); } catch (CryptographicException) { Console.WriteLine("Information could not be written out for this certificate."); } } }
