설명

이 생성자는 암호화된 데이터를 가리키는 URI(Uniform Resource Identifier)를 사용하여 개체를 만듭니다 CipherReference . 그런 다음 개체를 사용하여 개체에 대한 CipherData 참조 정보를 제공합니다.

URI를 사용하여 암호화된 데이터를 포함하는 XML 파일을 지정할 수 있습니다. 예를 들면 다음과 같습니다.

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

부분 URI를 사용하여 XML 문서의 일부만 암호화하도록 지정할 수도 있습니다. 예를 들어 document.xml 라는 XML 문서에 다음 XML 코드 예제와 같이 두 MyForm 개의 요소가 포함되어 있다고 가정합니다.

<MyForm Id='Form1'>

<! -- Form data here -->

</MyForm>

<MyForm Id='Form2'>

<! -- Form data here -->

</MyForm>

다음과 같은 URI를 사용하여 에서 Form2 콘텐츠만 암호화할 수 있습니다.

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

CipherReference(String, TransformChain)

CipherReference.cs

지정된 URI(Uniform Resource Identifier)와 변환 체인 정보를 사용하여 CipherReference 클래스의 새 인스턴스를 초기화합니다.

설명

이 생성자는 URI(Uniform Resource Identifier)와 변환 체인을 사용하여 암호화된 데이터를 나타내는 개체를 만듭니다 CipherReference . 그런 다음 개체를 사용하여 개체에 대한 CipherData 참조 정보를 제공합니다.
