我们如何获取 x509data 和 x509certificate 标记并将其附加到以下代码生成的 xml 

 String providerName = System.getProperty("jsr105Provider",
   "org.jcp.xml.dsig.internal.dom.XMLDSigRI");

 XMLSignatureFactory fac =
   XMLSignatureFactory.getInstance("DOM",
   (Provider) Class.forName(providerName).newInstance());

 Reference ref =
   fac.newReference("",
       fac.newDigestMethod(DigestMethod.SHA1, null),
           Collections.singletonList(
               fac.newTransform(Transform.ENVELOPED,(XMLStructure) null)), 
       null, null);

   SignedInfo si = fac.newSignedInfo
       (fac.newCanonicalizationMethod
         (CanonicalizationMethod.INCLUSIVE_WITH_COMMENTS, 
            (XMLStructure) null), 
        fac.newSignatureMethod(SignatureMethod.RSA_SHA1, 
            null),
        Collections.singletonList(ref));

   KeyPairGenerator kpg = 
       KeyPairGenerator.getInstance("RSA");
   kpg.initialize(512);
   KeyPair kp = kpg.generateKeyPair();

   KeyInfoFactory kif = fac.getKeyInfoFactory();
   KeyValue kv = kif.newKeyValue(kp.getPublic());

   KeyInfo ki = 
       kif.newKeyInfo(Collections.singletonList(kv));

   DocumentBuilderFactory dbf =
       DocumentBuilderFactory.newInstance();
   dbf.setNamespaceAware(true);
   Document doc1 = 
       dbf.newDocumentBuilder().
       parse(new FileInputStream("C:/Documents and Settings/sbtho/Desktop/downloads/samp.xml"));

   DOMSignContext dsc = new DOMSignContext
    (kp.getPrivate(), doc.getDocumentElement());


   XMLSignature signature = fac.newXMLSignature(si, ki);
      signature.sign(dsc);

   TransformerFactory tf = TransformerFactory.newInstance();
   Transformer trans = tf.newTransformer();

   trans.transform(
       new DOMSource(doc),
       new StreamResult(
           new FileOutputStream("C:/Documents and Settings/sbtho/Desktop/downloads/signedsamp.xml")));

上面代码的输出看起来像这样，我想在 keyinfo 标签内插入 x509 标签。

x509certificate 是如何创建的？

我知道这个问题已经有一段时间了，但是我遇到了同样的问题，并且我解决了它，所以我想分享解决方案它使用使用 iaik pkcs 工具从安全令牌获得的密钥库：

替换单例列表的技巧 vas

KeyInfo ki = 
   kif.newKeyInfo(Collections.singletonList(kv));

获取带有证书和键值的列表。

具有全部魔力的代码（希望对某人有所帮助）：

public void generateSignatureforResumen(String originalXmlFilePath,
        String destnSignedXmlFilePath, IAIKPkcs11 pkcs11Provider_, KeyStore tokenKeyStore, String pin) throws KeyStoreException, NoSuchAlgorithmException, UnrecoverableKeyException, GeneralSecurityException, TokenException  {
    //Get the XML Document object
    Document doc = getXmlDocument(originalXmlFilePath);
    //Create XML Signature Factory
    PrivateKey signatureKey_ = null;
    PublicKey pubKey_ = null;
    X509Certificate signingCertificate_ = null;
    Boolean prik = false;
    Boolean pubk = false;
    Enumeration aliases = tokenKeyStore.aliases();
    while (aliases.hasMoreElements()) {
      String keyAlias = aliases.nextElement().toString();
      java.security.Key key = tokenKeyStore.getKey(keyAlias, pin.toCharArray());
      if (key instanceof java.security.interfaces.RSAPrivateKey) {
        Certificate[] certificateChain = tokenKeyStore.getCertificateChain(keyAlias);
        X509Certificate signerCertificate = (X509Certificate) certificateChain[0];
        boolean[] keyUsage = signerCertificate.getKeyUsage();
        // check for digital signature or non-repudiation,
        // but also accept if none is set
        if ((keyUsage == null) || keyUsage[0] || keyUsage[1]) {
          signatureKey_ = (PrivateKey) key;
          signingCertificate_ = signerCertificate;
          prik = true;
          pubKey_ = signerCertificate.getPublicKey();
          break;
        }
      } 
    }


    if (signatureKey_ == null) {
      throw new GeneralSecurityException(
          "Found no signature key. Ensure that a valid card is inserted.");
    }

     XMLSignatureFactory xmlSigFactory = XMLSignatureFactory.getInstance("DOM");
        Reference ref = null;
        SignedInfo signedInfo = null;
        try {
            ref = xmlSigFactory.newReference("", xmlSigFactory.newDigestMethod(DigestMethod.SHA1, null),
                    Collections.singletonList(xmlSigFactory.newTransform(Transform.ENVELOPED,
                    (TransformParameterSpec) null)), null, null);
            signedInfo = xmlSigFactory.newSignedInfo(
                    xmlSigFactory.newCanonicalizationMethod(CanonicalizationMethod.INCLUSIVE,
                    (C14NMethodParameterSpec) null),
                    xmlSigFactory.newSignatureMethod(SignatureMethod.RSA_SHA1, null),
                    Collections.singletonList(ref));


        } catch (NoSuchAlgorithmException ex) {
            ex.printStackTrace();
        } 
        KeyInfoFactory kif = xmlSigFactory.getKeyInfoFactory();
        X509Data x509data = kif.newX509Data(Collections.nCopies(1, signingCertificate_));
        KeyValue kval = kif.newKeyValue(pubKey_);
        List keyInfoItems = new ArrayList();
        keyInfoItems.add(kval);
        keyInfoItems.add(x509data);
        //Object list[];
        KeyInfo keyInfo = kif.newKeyInfo(keyInfoItems);
//Create a new XML Signature
    XMLSignature xmlSignature = xmlSigFactory.newXMLSignature(signedInfo, keyInfo);



    DOMSignContext domSignCtx = new DOMSignContext((Key) signatureKey_, doc.getDocumentElement());


    try {
        //Sign the document
        xmlSignature.sign(domSignCtx);
    } catch (MarshalException ex) {
        ex.printStackTrace();
    } catch (XMLSignatureException ex) {
        ex.printStackTrace();
    }
    //Store the digitally signed document inta a location
    storeSignedDoc(doc, destnSignedXmlFilePath);
