Keterangan
Konstruktor ini membuat CipherReference objek menggunakan Pengidentifikasi Sumber Daya Seragam (URI) yang menunjuk ke data terenkripsi. Objek kemudian digunakan untuk memberikan informasi referensi untuk objek CipherData .
Anda dapat menggunakan URI untuk menunjuk file XML yang berisi data terenkripsi. Contohnya:
String uri = "http://www.woodgrovebank.com/document.xml";
Anda juga dapat menggunakan URI parsial untuk menunjuk bahwa hanya sebagian dokumen XML yang akan dienkripsi. Misalnya, asumsikan bahwa dokumen XML bernama document.xml berisi dua MyForm
elemen seperti yang ditunjukkan dalam contoh kode XML berikut:
<MyForm Id='Form1'>
<! -- Form data here -->
</MyForm>
<MyForm Id='Form2'>
<! -- Form data here -->
</MyForm>
Anda hanya dapat mengenkripsi konten dalam Form2
menggunakan URI seperti berikut ini:
String uri = "http://www.woodgrovebank.com/document.xml#Form2";
