RSACryptoServiceProvider.UseMachineKeyStore Свойство
Определение
Важно!
Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Получает или задает значение, указывающее, следует ли сохранять ключ в хранилище ключей компьютера, а не в хранилище профилей пользователей.
public:
static property bool UseMachineKeyStore { bool get(); void set(bool value); };
public static bool UseMachineKeyStore { get; set; }
static member UseMachineKeyStore : bool with get, set
Public Shared Property UseMachineKeyStore As Boolean
Значение свойства
Значение true
, если ключ необходимо сохранить в хранилище ключей компьютера; в противном случае — значение false
.
Примеры
В следующем примере кода создается RSACryptoServiceProvider объект и задается статическое UseMachineKeyStore свойство для использования хранилища ключей компьютера вместо хранилища ключей профиля пользователя.

Комментарии
Присвоение этому свойству значения true
эквивалентно передаче флага UseMachineKeyStore объекту CspParameters . Свойство UseMachineKeyStore применяется ко всему коду в текущем домене приложения, тогда как CspParameters объект применяется только к классам, явно ссылающимся на него. Эти параметры полезны при олицетворении или запуске под учетной записью, профиль пользователя которой не загружен. Параметр UseMachineKeyStore влияет на расположение хранилища ключей, только если RSACryptoServiceProvider инициализирован без параметров.
