Represents the C14N XML canonicalization transform for a digital signature as defined by the World Wide Web Consortium (W3C), with comments.
See Also: XmlDsigC14NWithCommentsTransform Members
The System.Security.Cryptography.Xml.XmlDsigC14NWithCommentsTransform class represents the C14N XML canonicalization transform that describes the canonical form of an XML document. This transform allows a signer to create a digest using the canonical form of an XML document. A recipient can then verify the digital signature using the same canonical form of the XML document with the same transform.
Use the System.Security.Cryptography.Xml.XmlDsigC14NWithCommentsTransform class when you need to sign an XML document that contains comments.
Note that you cannot directly create a new instance of a canonicalization transform class. To specify a canonicalization transform, pass the Uniform Resource Identifier (URI) that describes the transform to the SignedInfo.CanonicalizationMethod property, which is accessible from the SignedXml.SignedInfo property. To acquire a reference to the canonicalization transform, use the SignedInfo.CanonicalizationMethodObject property, which is accessible from the SignedXml.SignedInfo property.
The URI that describes the System.Security.Cryptography.Xml.XmlDsigExcC14NWithCommentsTransform class is defined by the SignedXml.XmlDsigExcC14NWithCommentsTransformUrl field.
The URI that describes the System.Security.Cryptography.Xml.XmlDsigC14NWithCommentsTransform class is defined by the SignedXml.XmlDsigC14NWithCommentsTransformUrl field and the SignedXml.XmlDsigCanonicalizationWithCommentsUrl field.
For more information about the C14N with comments transform, see Sections 6.5 and 6.6.1 of the XMLDSIG specification, which is available from the World Wide Web Consortium (W3C) at www.w3.org/TR/xmldsig-core/. The canonicalization algorithm is defined in the W3C Canonical XML specification, which is available at www.w3.org/TR/xml-c14n.
