Assembly:

System.Net.Security.dll

Source:

SslStream.cs

Obtient l'algorithme utilisé pour générer des codes d'authentification de messages (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

Valeur de propriété

HashAlgorithmType

Algorithme utilisé pour générer des codes d’authentification de message (MAC).

Exceptions

InvalidOperationException

L'accès à la propriété HashAlgorithm a été effectué avant la fin du processus d'authentification ou le processus d'authentification a échoué.

Exemples

L’exemple de code suivant affiche les paramètres de chiffrement pour le flux spécifié.

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

Remarques

Les algorithmes d’authentification de message génèrent des hachages et des signatures de message utilisés pour détecter la falsification et la falsification.
