Definition

C#
public override int GetHashCode ();

Returns

The hash code for the X.509 certificate as an integer.

Examples

The following example uses the GetHashCode method to return an integer representation of a certificate's hash code and displays it to the console.

C#

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.
        int results = cert.GetHashCode();

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

Remarks

If the X.509 certificate hash is an array of more than 4 bytes, any byte after the fourth byte is not seen in this integer representation.
