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 Integer = cert.GetHashCode()

      ' Display the value to the console.
      Console.WriteLine(results)
