This package includes classes that represent the core elements defined in the W3C XML digital signature specification:{@link javax.xml.crypto.dsig.XMLSignature XMLSignature},{@link javax.xml.crypto.dsig.SignedInfo SignedInfo},{@link javax.xml.crypto.dsig.CanonicalizationMethod CanonicalizationMethod},{@link javax.xml.crypto.dsig.SignatureMethod SignatureMethod},{@link javax.xml.crypto.dsig.Reference Reference}, {@link javax.xml.crypto.dsig.DigestMethod DigestMethod},{@link javax.xml.crypto.dsig.XMLObject XMLObject}, {@link javax.xml.crypto.dsig.Manifest Manifest},{@link javax.xml.crypto.dsig.SignatureProperties SignatureProperties}, and{@link javax.xml.crypto.dsig.SignatureProperty SignatureProperty}. <code>KeyInfo</code> typesare defined in the {@link javax.xml.crypto.dsig.keyinfo} subpackage.{@link javax.xml.crypto.dsig.XMLSignatureFactory XMLSignatureFactory}is an abstract factory that creates {@link javax.xml.crypto.dsig.XMLSignature XMLSignature} objects from scratchor from a pre-existing XML representation, such as a DOM node.{@link javax.xml.crypto.dsig.TransformService} is a service providerinterface for creating and plugging in implementations oftransform and canonicalization algorithms. <p>Of primary significance in this package is the {@link javax.xml.crypto.dsig.XMLSignature XMLSignature} class,which allows you to sign and validate an XML digital signature. <h2>Package Specification</h2> <ul><li><a href="http://www.w3.org/TR/xmldsig-core/">XML-Signature Syntax and Processing: W3C Recommendation</a><li><a href="http://www.ietf.org/rfc/rfc3275.txt">RFC 3275: XML-Signature Syntax and Processing</a></ul> <p><dl><dt><b>Since:</b></dt>  <dd>1.6</dd></dl> </body></html>
