Açıklamalar

Bu oluşturucu, şifrelenmiş verilere işaret eden tekdüzen Kaynak Tanımlayıcısı (URI) kullanarak bir CipherReference nesne oluşturur. Nesne daha sonra bir CipherData nesne için başvuru bilgileri sağlamak için kullanılır.

Şifrelenmiş veriler içeren bir XML dosyası ayarlamak için URI kullanabilirsiniz. Örnek:

String uri = "http://www.woodgrovebank.com/document.xml";

Xml belgesinin yalnızca bir bölümünün şifrelenmesini sağlamak için kısmi bir URI de kullanabilirsiniz. Örneğin, document.xml adlı bir XML belgesinin aşağıdaki XML kodu örneğinde gösterildiği gibi iki MyForm öğe içerdiğini varsayalım:

<MyForm Id='Form1'>

<! -- Form data here -->

</MyForm>

<MyForm Id='Form2'>

<! -- Form data here -->

</MyForm>

Aşağıdaki gibi bir URI kullanarak yalnızca içindeki Form2 içeriği şifreleyebilirsiniz:

String uri = "http://www.woodgrovebank.com/document.xml#Form2";

Açıklamalar

Bu oluşturucu, şifrelenmiş verileri göstermek için Tekdüzen Kaynak Tanımlayıcısı (URI) ve dönüştürme zinciri kullanarak bir CipherReference nesne oluşturur. Nesne daha sonra bir CipherData nesne için başvuru bilgileri sağlamak için kullanılır.
