You can use a custom model binder for this parameter

// /Controller/Example/0000000A
public ActionResult Example([ModelBinder(typeof(EncryptDataBinder))]int id)
{
    return View(id);
}

The model binder

public class EncryptDataBinder : DefaultModelBinder
{
    public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
    {
        if (bindingContext.ModelType == typeof(int))
        {
            var valueProviderResult = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);
            if (valueProviderResult != null)
            {
                // Use your own logic here
                bytes = ConvertUtilities.ToBytesFromHexa((string)valueProviderResult.RawValue);
                return BitConverter.ToInt32(bytes, 0);
            }
        }

        return base.BindModel(controllerContext, bindingContext);
    }
}
