Si no se especifica un valor en el archivo de configuración para encryptionpolicy, el EncryptionPolicy valor predeterminado EncryptionPolicy.RequireEncryption para la SslStream instancia que se construye.

El uso del cifrado Null es necesario cuando la directiva de cifrado se establece EncryptionPolicy.NoEncryptionen .

Comentarios

Cuando se especifica true para el leaveStreamOpen parámetro , el cierre SslStream no tiene ningún efecto en la innerStream secuencia; debe cerrarse innerStream explícitamente cuando ya no lo necesite.

Si no se especifica un valor en el archivo de configuración para encryptionpolicy, el EncryptionPolicy valor predeterminado EncryptionPolicy.RequireEncryption para la SslStream instancia que se construye.

El uso del cifrado Null es necesario cuando la directiva de cifrado se establece EncryptionPolicy.NoEncryptionen .

En el ejemplo de código siguiente se crea SslStream e inicia la parte del cliente de la autenticación.

// Create a TCP/IP client socket.
// machineName is the host running the server application.
TcpClient client = new TcpClient(machineName,5000);
Console.WriteLine("Client connected.");
// Create an SSL stream that will close the client's stream.
SslStream sslStream = new SslStream(
    client.GetStream(),
    false,
    new RemoteCertificateValidationCallback (ValidateServerCertificate),
    null
    );
// The server name must match the name on the server certificate.
try
{
    sslStream.AuthenticateAsClient(serverName);
}

Cuando se especifica true para el leaveStreamOpen parámetro , el cierre SslStream no tiene ningún efecto en la innerStream secuencia; debe cerrarse innerStream explícitamente cuando ya no lo necesite.

El argumento userCertificateValidationCallback del delegado certificateErrors contiene los códigos de error Windows devueltos por el canal Security Support Provider Interface (SSPI). El valor devuelto del método invocado por el userCertificateValidationCallback delegado determina si la autenticación se realiza correctamente.

El protocolo de seguridad y los algoritmos criptográficos ya están seleccionados cuando se invoca el userCertificateValidationCallback método del delegado. Puede usar el método para determinar si los algoritmos criptográficos y puntos fuertes seleccionados son suficientes para la aplicación. Si no es así, el método debe devolver false para evitar que SslStream se cree .

Si no se especifica un valor en el archivo de configuración para encryptionpolicy, el EncryptionPolicy valor predeterminado EncryptionPolicy.RequireEncryption para la SslStream instancia que se construye.

El userCertificateSelectionCallback delegado es útil cuando la aplicación tiene varios certificados y debe elegir dinámicamente un certificado. Los certificados del almacén "MY" se pasan al método invocado por el delegado.
