Beispiele

Im folgenden Beispiel wird die GetKeyAlgorithm Methode verwendet, um den Schlüsselalgorithmus eines Zertifikats im Zeichenfolgenformat abzurufen und in der Konsole anzuzeigen.

using namespace System;
using namespace System::Security::Cryptography::X509Certificates;
int 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.
   String^ results = cert->GetKeyAlgorithm();
   
   // Display the value to the console.
   Console::WriteLine( results );
}

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

public class X509

        string Certificate =  "Certificate.cer";

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

        // Get the value.
        string results = cert.GetKeyAlgorithm();

        // Display the value to the console.
        Console.WriteLine(results);
    }
