Returns the hash code for the X.509v3 certificate as an integer.

Namespace: System.Security.Cryptography.X509Certificates
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Overrides Function GetHashCode As Integer
public override int GetHashCode()
public:
virtual int GetHashCode() override
abstract GetHashCode : unit -> int 
override GetHashCode : unit -> int 

Return Value

Type: System..::.Int32
The hash code for the X.509 certificate as an integer.
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.

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.

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 Integer = cert.GetHashCode()

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