SslStream.KeyExchangeStrength 屬性

定義

命名空間:

System.Net.Security

組件:

System.Net.Security.dll

來源:

SslStream.cs

取得值，識別這個執行個體所用之金鑰交換演算法的強度。

public:
 virtual property int KeyExchangeStrength { int get(); };

public virtual int KeyExchangeStrength { get; }

member this.KeyExchangeStrength : int

Public Overridable ReadOnly Property KeyExchangeStrength As Integer

屬性值

Int32

Int32 值，指定 ExchangeAlgorithmType 演算法的強度 (以位元為單位)。

範例

下列程式碼範例會顯示指定資料流程的密碼編譯設定。

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
