Définition

Espace de noms:

System.Net.Security

Assembly:

System.Net.Security.dll

Source:

SslStream.cs

Obtient une valeur qui identifie la puissance de l'algorithme de chiffrement utilisé par ce SslStream.

public:
 virtual property int CipherStrength { int get(); };

public virtual int CipherStrength { get; }

member this.CipherStrength : int

Public Overridable ReadOnly Property CipherStrength As Integer

Valeur de propriété

Int32

Valeur Int32 qui spécifie la puissance de l'algorithme, en bits.

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
