Reference '' cannot be validated


I tried validate signature if i change something in file and add more than one signature. I got error like this:

xades4j.verification.ReferenceValueException: Reference '' cannot be validated
at xades4j.verification.XadesVerifierImpl.doCoreVerification(XadesVerifierImpl.java:306)

this is my code:

        try (FileInputStream fis = new FileInputStream("F:/keystore/xml_encrypt.p12")) {

            Enumeration<String> aliases = ks.aliases();
            while (aliases.hasMoreElements()) {
                aliases.nextElement();
            }
        }

        CertificateValidationProvider provider = new PKIXCertificateValidationProvider(
                ks, false);
        XadesVerificationProfile profile = new XadesVerificationProfile(provider);
        Element sigElem = (Element) nl.item(0);
        //XAdESVerificationResult r = profile.newVerifier().verify(sigElem, null);

I'm newbie xades4j. Thank in advance.


Solution

  • It seems that you have a Reference element with an empty URI. For this kind of URIs, the way to obtain the signed data object contents is "application specific". In xades4j you can specify it using SignatureSpecificVerificationOptions

    EDIT: the "application specific" way is actually for references where the URI attribute is omitted and there can be at most one of those in a signature. Having an empty reference means that the reference covers the whole XML resource. Depending on how you're adding an additional signature, the actual input for the reference validation may change and it could fail.

    Can you show how you're creating the XML document?
