SslStream.HashAlgorithm 屬性

定義

命名空間:

System.Net.Security

組件:

System.Net.Security.dll

來源:

SslStream.cs

取得用於產生訊息驗證碼 (MAC) 的演算法。

public:
 virtual property System::Security::Authentication::HashAlgorithmType HashAlgorithm { System::Security::Authentication::HashAlgorithmType get(); };

public virtual System.Security.Authentication.HashAlgorithmType HashAlgorithm { get; }

member this.HashAlgorithm : System.Security.Authentication.HashAlgorithmType

Public Overridable ReadOnly Property HashAlgorithm As HashAlgorithmType

屬性值

HashAlgorithmType

用於產生訊息驗證碼的演算法 (MA) 。

例外狀況

InvalidOperationException

HashAlgorithm 屬性在驗證程序尚未完成之前即遭人存取，或是驗證程序失敗。

範例

下列程式代碼範例會顯示指定數據流的密碼編譯設定。

static void DisplaySecurityLevel( SslStream^ stream )
{
   Console::WriteLine( L"Cipher: {0} strength {1}", stream->CipherAlgorithm, stream->CipherStrength );
   Console::WriteLine( L"Hash: {0} strength {1}", stream->HashAlgorithm, stream->HashStrength );
   Console::WriteLine( L"Key exchange: {0} strength {1}", stream->KeyExchangeAlgorithm, stream->KeyExchangeStrength );
   Console::WriteLine( L"Protocol: {0}", stream->SslProtocol );
}

static void DisplaySecurityLevel(SslStream stream)
{
   Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength);
   Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength);
   Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength);
   Console.WriteLine("Protocol: {0}", stream.SslProtocol);
}

Private Shared Sub DisplaySecurityLevel(stream As SslStream)
    Console.WriteLine("Cipher: {0} strength {1}", stream.CipherAlgorithm, stream.CipherStrength)
    Console.WriteLine("Hash: {0} strength {1}", stream.HashAlgorithm, stream.HashStrength)
    Console.WriteLine("Key exchange: {0} strength {1}", stream.KeyExchangeAlgorithm, stream.KeyExchangeStrength)
    Console.WriteLine("Protocol: {0}", stream.SslProtocol)
End Sub

備註

訊息驗證演算法會產生用來偵測竄改和偽造的訊息哈希和簽章。
