SslStream.CipherAlgorithm 属性
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获取一个值，该值确定此 SslStream 使用的批量加密算法。
public:
virtual property System::Security::Authentication::CipherAlgorithmType CipherAlgorithm { System::Security::Authentication::CipherAlgorithmType get(); };C#
public virtual System.Security.Authentication.CipherAlgorithmType CipherAlgorithm { get; }member this.CipherAlgorithm : System.Security.Authentication.CipherAlgorithmTypePublic Overridable ReadOnly Property CipherAlgorithm As CipherAlgorithmType一个 值，该值标识此 SslStream使用的批量加密算法。
CipherAlgorithm 属性是在身份验证过程未完成时访问的或者身份验证过程失败。
下面的代码示例显示指定流的加密设置。
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 );
}
C#
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
使用枚举值Null构造SslStream实例时，NoEncryption属性需要 CipherAlgorithm 值。
Windows Server 2003 和 Windows XP 不支持 Null 值。 因此， Null 即使值用于构造 SslStream 实例，属性 EncryptionPolicy 也将为 None。 该值 Null 仅在 Windows Vista 及更高版本上返回。
