重载

GetCertHashString()	以十六进制字符串的形式返回 X.509v3 证书的 SHA1 哈希值。
GetCertHashString(HashAlgorithmName)	返回包含使用指定加密哈希算法计算的 X.509v3 证书的哈希值的十六进制字符串。

GetCertHashString()

Source:

X509Certificate.cs

以十六进制字符串的形式返回 X.509v3 证书的 SHA1 哈希值。

public:
 virtual System::String ^ GetCertHashString();

public virtual string GetCertHashString ();

abstract member GetCertHashString : unit -> string
override this.GetCertHashString : unit -> string

Public Overridable Function GetCertHashString () As String

返回

String

X.509 证书哈希值的十六进制字符串表示形式。

示例

以下示例使用 GetCertHashString 方法获取 X.509 证书哈希值，将其转换为字符串，并将其显示到控制台。

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.
   String^ results = cert->GetCertHashString();
   
   // 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.
        string results = cert.GetCertHashString();

        // 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 String = cert.GetCertHashString()
      
      ' Display the value to the console.
      Console.WriteLine(results)
   End Sub 
End Class

GetCertHashString(HashAlgorithmName)

Source:

X509Certificate.cs
