Комментарии
Этот конструктор создает CipherReference объект с помощью универсального кода ресурса (URI), который указывает на зашифрованные данные. Затем объект используется для предоставления ссылочных сведений CipherData для объекта .
Для назначения XML-файла, содержащего зашифрованные данные, можно использовать универсальный код ресурса (URI). Пример:
String uri = "http://www.woodgrovebank.com/document.xml";
Вы также можете использовать частичный универсальный код ресурса (URI), чтобы указать, что шифруется только часть XML-документа. Например, предположим, что XML-документ с именем document.xml содержит два MyForm
элемента, как показано в следующем примере КОДА XML:
<MyForm Id='Form1'>
<! -- Form data here -->
</MyForm>
<MyForm Id='Form2'>
<! -- Form data here -->
</MyForm>
Вы можете зашифровать только содержимое в Form2
с помощью URI, например следующего:
String uri = "http://www.woodgrovebank.com/document.xml#Form2";
