例

次のコード例では、指定したストリームの暗号化設定を表示します。

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
