Для гугл-путешественников, прибывающих сюда:
В этой ветке форума MSDN говорится, что в Windows есть API CryptUIWizDigitalSign . Это также указывает на статью в блоге Алехандро Кампоса Мадженсио, в которой показан пример реализации в VB.NET.
Поскольку версия C #, похоже, отсутствует, я преобразовал код Алехандро в C #. Обратите внимание, что следующий код работает только с файлами (пока).
