SslStream.HashAlgorithm 属性

定义

命名空间:

System.Net.Security

程序集:

System.Net.Security.dll

Source:

SslStream.cs

获取用于生成消息身份验证代码 (MAC) 的算法。

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

属性值

HashAlgorithmType

用于生成消息身份验证代码的算法 (MAC) 。

例外

InvalidOperationException

HashAlgorithm 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。

示例

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 );
}

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

注解

消息身份验证算法生成用于检测篡改和伪造的消息哈希和签名。
