SslStream.CipherAlgorithm Propriedade

Definição

Cuidado

KeyExchangeAlgorithm, KeyExchangeStrength, CipherAlgorithm, CipherStrength, HashAlgorithm and HashStrength properties of SslStream are obsolete. Use NegotiatedCipherSuite instead.

Obtém um valor que identifica o algoritmo de criptografia em massa usado por isso SslStream.

Valor da propriedade

Um valor que identifica o algoritmo de criptografia em massa usado por isso SslStream.

Atributos

Exceções

A CipherAlgorithm propriedade foi acessada antes da conclusão do processo de autenticação ou o processo de autenticação falhou.

Exemplos

O exemplo de código a seguir exibe as configurações de criptografia para o fluxo especificado.

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

Comentários

Um valor de Null é necessário para a CipherAlgorithm propriedade quando o valor de NoEncryption enumeração é usado para construir uma SslStream instância.

O Windows Server 2003 e o Windows XP não dão suporte ao Null valor. Portanto, mesmo que o Null valor seja usado para construir a SslStream instância, a EncryptionPolicy propriedade será None. O Null valor só é retornado no Windows Vista e posterior.
