SslStream.HashAlgorithm Properti

Definisi

Ruang nama:

System.Net.Security

Rakitan:

System.Net.Security.dll

Sumber:

SslStream.cs

Mendapatkan algoritma yang digunakan untuk menghasilkan kode autentikasi pesan (MAC).

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

Nilai Properti

HashAlgorithmType

Algoritma yang digunakan untuk menghasilkan kode autentikasi pesan (MAC).

Pengecualian

InvalidOperationException

Properti HashAlgorithm diakses sebelum proses autentikasi selesai atau proses autentikasi gagal.

Contoh

Contoh kode berikut menampilkan pengaturan kriptografi untuk aliran yang ditentukan.

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

Keterangan

Algoritma autentikasi pesan menghasilkan hash dan tanda tangan pesan yang digunakan untuk mendeteksi perubahan dan pemalsuan.
