X509Certificate.GetHashCode 方法

定义

命名空间:

System.Security.Cryptography.X509Certificates

程序集:

System.Security.Cryptography.dll

Source:

X509Certificate.cs

返回整数形式的 X.509v3 证书的哈希代码。

public:
 override int GetHashCode();

public override int GetHashCode ();

override this.GetHashCode : unit -> int

Public Overrides Function GetHashCode () As Integer

返回

Int32

整数形式的 X.509 证书的哈希代码。

示例

以下示例使用 GetHashCode 方法返回证书哈希代码的整数表示形式，并将其显示给控制台。

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.
   int results = cert->GetHashCode();
   
   // Display the value to the console.
   Console::WriteLine( results );
}

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);
    }
}

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

注解

如果 X.509 证书哈希是一个超过 4 个字节的数组，则此整数表示形式中看不到第四个字节之后的任何字节。
