XAdESSignatureImpl

public interface XAdESSignature
extends XMLSignature

A representation of the XML Advanced Electronic Signature as defined in ETSI TS 101 903 v1.3.2.

The XAdESSignature extends the XMLSignature by providing methods for appending (unsigned) QualifyingProperties to the already signed XMLSignature.

A XML Advanced Electronic Signature (XAdES) is a XML Digital Signature (XMLDSig) as defined by the W3C Recommendation XML-Signature Syntax and Processing with a set of properties qualifying the signature and the signed data objects respectively. There are different forms of XML Advanced Electronic Signatures requiring different types of properties to be present in the signature.

• XAdES-BES Basic Electronic Signature
• XAdES-EPES Explicit Policy Based Electronic Signature
• XAdES-T Electronic Signature with Time
• XAdES-C Electronic Signature with Complete validation data references
• XAdES-X eXtended Signatures with time
• XAdES-X-L eXtended Long electronic signatures with time
• XAdES-A Archival electronic signatures

Incorporation of qualifying properties

Properties qualifying the signature or the signed data are incorporated into the ds:Signature by appending a QualifyingProperties element as child element of an ds:Object.

   XMLSignatureFactory sigfac = XMLSignatureFactory.getInstance();
   QualifyingPropertiesFactory qpfac = QualifyingPropertiesFactory.getInstance();

   SignedSignatureProperties sp = qpfac.newSignedProperties(...);
   QualifyingProperties qp = qpfac.newQualifyingProperties(sp, "#Signature", "QualifyingProperties");
   XMLObject obj = sigfac.newXMLObject(Collections.singletonList(qp), null, null, null);


 

The qualifying properties are split into properties that are signed with the signature (SignedProperties) and properties that are not signed with the signature (UnsignedProperties). The signed properties have to be covered by a ds:Reference to the SignedProperties element.

 Reference qpRef = sigfac.newReference("#QualifyingProperties",
     sigfac.newDigestMethod(DigestMethod.SHA1, null), null,
     SignedProperties.REFERENCE_TYPE, "SignedPropertiesReference");
