定義

命名空間:

System.Security.Cryptography.X509Certificates

組件:

System.Security.Cryptography.dll

多載

GetCertHash()	將 X.509v3 憑證的雜湊值 (Hash Value) 傳回為位元組陣列。
GetCertHash(HashAlgorithmName)	傳回使用指定密碼編譯雜湊演算法所計算 X.509v3 憑證的雜湊值。

GetCertHash()

來源:

X509Certificate.cs

將 X.509v3 憑證的雜湊值 (Hash Value) 傳回為位元組陣列。

public:
 virtual cli::array <System::Byte> ^ GetCertHash();

public virtual byte[] GetCertHash ();

abstract member GetCertHash : unit -> byte[]
override this.GetCertHash : unit -> byte[]

Public Overridable Function GetCertHash () As Byte()

傳回

Byte[]

X.509 憑證的雜湊值。

範例

下列範例會使用 方法， GetCertHash 以 X.509 憑證的哈希值填入位元組陣列陣列。

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.
   array<Byte>^results = cert->GetCertHash();
}

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.
        byte[] results = cert.GetCertHash();
    }
}

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 Byte() = cert.GetCertHash()
   End Sub 
End Class

GetCertHash(HashAlgorithmName)

來源:

X509Certificate.cs

傳回使用指定密碼編譯雜湊演算法所計算 X.509v3 憑證的雜湊值。

public:
 virtual cli::array <System::Byte> ^ GetCertHash(System::Security::Cryptography::HashAlgorithmName hashAlgorithm);

public virtual byte[] GetCertHash (System.Security.Cryptography.HashAlgorithmName hashAlgorithm);

abstract member GetCertHash : System.Security.Cryptography.HashAlgorithmName -> byte[]
override this.GetCertHash : System.Security.Cryptography.HashAlgorithmName -> byte[]

Public Overridable Function GetCertHash (hashAlgorithm As HashAlgorithmName) As Byte()

參數

hashAlgorithm

HashAlgorithmName

要使用的密碼編譯雜湊演算法名稱。

傳回

Byte[]

位元組陣列，其中包含 X.509 憑證的雜湊值。

例外狀況

ArgumentException

hashAlgorithm.Name 是 null 或空字串。

CryptographicException

hashAlgorithm 不是已知的雜湊演算法。
