System.Security.Cryptography.Xml.Transform Class

Represents the abstract base class from which all <Transform> elements that can be used in an XML digital signature derive.

See Also: Transform Members

Syntax

public abstract class Transform

Remarks

When performing XML signing and verification, the <Transform> element describes how the signer transformed the data object that was signed. The verifier of a document then uses the <Transform> element to transform the signed data in the same manner. If the verifier cannot transform the signed data in the same manner, the document cannot be verified.

Use a class that derives from the System.Security.Cryptography.Xml.Transform class whenever you need to add one or more transform objects to an encrypted XML document or to a signed XML document.

For more information about the <Transform> element, see the XMLDSIG specification, which is available from the World Wide Web Consortium (W3C) at www.w3.org/TR/xmldsig-core/, or the XML encryption specification, which is available from the W3C at www.w3.org/TR/xmlenc-core/.
