Uitzonderingen

Voorbeelden

In het volgende voorbeeld wordt de methode gebruikt om de GetPublicKey openbare sleutel van een certificaat als matrix van bytes te retourneren en weer te geven aan de console.

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

public class X509
{

    public static void Main()
    {

        // The path to the certificate.
        string Certificate =  "Certificate.cer";

        // Load the certificate into an X509Certificate object.
        X509Certificate cert = X509Certificate.CreateFromCertFile(Certificate);

        // Get the value.
        byte[] results = cert.GetPublicKey();

        // Display the value to the console.
        foreach(byte b in results)
        {
            Console.Write(b);
        }
    }
}

Imports System.Security.Cryptography.X509Certificates




Public Class X509
   
   
   Public Shared Sub Main()
      
      ' The path to the certificate.
      Dim Certificate As String = "Certificate.cer"
      
      ' Load the certificate into an X509Certificate object.
      Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(Certificate)
      
      ' Get the value.
      Dim results As Byte() = cert.GetPublicKey()
      
      ' Display the value to the console.
      Dim b As Byte
      For Each b In  results
         Console.Write(b)
      Next b
   End Sub
End Class

Opmerkingen

Deze waarde komt overeen met de inhoud van het subjectPublicKey veld van de SubjectPublicKeyInfo-gegevens in het certificaat.
