java - Xades4j 验证 - 无法创建空 :null from a http://www. w3.org/2000/09/xmldsig#

Question

我正在尝试编写应该使用 xades4j 库验证 XML 符号的程序。

我有这样的东西:

public static void verify() throws Exception
         {
        FileSystemDirectoryCertStore certStore = new     FileSystemDirectoryCertStore("C:\\(...)");
        KeyStore trustAnchors = KeyStore.getInstance("jks");
        trustAnchors.load(null);
        CertificateValidationProvider certValidator = new PKIXCertificateValidationProvider(trustAnchors, false, certStore.getStore());

        XadesVerificationProfile p = new XadesVerificationProfile(certValidator);
        XadesVerifier v = p.newVerifier();

        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();     
        String  pathToXmlFile = "C:\\(..)\\TEST20140709_04.xml";

        Document docSource = builder.parse(new FileInputStream(pathToXmlFile));
        docSource.getDocumentElement();

        //Element sigElem = (Element)factory.newDocumentBuilder().parse(new FileInputStream(pathToXmlFile));
        Element sigElem =  docSource.getDocumentElement();
        SignatureSpecificVerificationOptions ssvo = new SignatureSpecificVerificationOptions();
        ssvo.useBaseUri("http://www.ietf.org/rfc/");

        XAdESVerificationResult r = v.verify(sigElem, ssvo);


System.out.println(r.getSignatureForm());
System.out.println(r.getSignatureAlgorithmUri());
System.out.println(r.getSignedDataObjects().size());
System.out.println(r.getQualifyingProperties().all().size());
    }

我收到此异常:

Exception in thread "main" xades4j.xml.unmarshalling.UnmarshalException: Bad XML signature

trustAnchors 的大小为 0 - 不应该 > 0？你能指出我哪里出错了吗？

Answer 1

我注意到两件事:

• DocumentBuilderFactory 应该 be namespace aware .
• 您没有将任何内容加载到信任 anchor keystore 中。您可能想要load it from a file .

如果解码异常仍然存在，则签名 XML 上可能存在错误。
