Represents an <X509Data> subelement of an XMLDSIG or XML Encryption <KeyInfo> element.
Assembly: System.Security (in System.Security.dll)
The class represents the <X509Data> element that contains X.509v3 certificate information related to the validation or encryption key. For example, an <X509Data> element might contain an X.509 certificate whose subject public key is the validation key, or a chain of X.509 certificates that terminate in a certificate for the validating key, or other identifiers for related X.509 certificates.
Use the class whenever you need to include X.509 certificate data in an encrypted or signed XML document.
For more information about the <X509Data> element, see Section 4.4.4 of the XMLDSIG specification, which is available from the World Wide Web Consortium (W3C) at www.w3.org/TR/xmldsig-core/, or see the XML Encryption specification, which is available from the W3C at www.w3.org/TR/xmlenc-core/.
This section contains two code examples. The first example demonstrates how to sign an XML file using a detached signature. The second example demonstrates how to sign an XML file using an envelope signature.
