SslStream.CipherAlgorithm 屬性

定義

取得值,識別這個 SslStream 所用的大量加密演算法。

public:
 virtual property System::Security::Authentication::CipherAlgorithmType CipherAlgorithm { System::Security::Authentication::CipherAlgorithmType get(); };
public virtual System.Security.Authentication.CipherAlgorithmType CipherAlgorithm { get; }
member this.CipherAlgorithm : System.Security.Authentication.CipherAlgorithmType
Public Overridable ReadOnly Property CipherAlgorithm As CipherAlgorithmType

屬性值

值,識別這個 SslStream所使用的大量加密演算法。

例外狀況

CipherAlgorithm 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

當列舉值用來建構SslStream實例時NoEncryption,屬性需要 CipherAlgorithm 的值Null

Windows Server 2003 和 Windows XP 不支援 Null 此值。 因此,即使 Null 使用 值來建構 SslStream 實例, EncryptionPolicy 屬性也會是 NoneNull此值只會在 Windows Vista 和更新版本上傳回。
