Precaución

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

Obtiene el algoritmo utilizado para generar códigos de autenticación de mensajes (MAC).

Atributos
ObsoleteAttribute

Excepciones

InvalidOperationException

Se HashAlgorithm obtuvo acceso a la propiedad antes de que se complete el proceso de autenticación o se produjo un error en el proceso de autenticación.

Ejemplos

En el ejemplo de código siguiente se muestra la configuración de criptografía de la secuencia especificada.

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

Comentarios

Los algoritmos de autenticación de mensajes generan hash de mensajes y firmas que se usan para detectar alteraciones y falsificaciones.
