Xades4j - 如何输入 SHA256 的哈希值？

问题描述

我需要使用 XAdES-EPES 封装的 RSA-SHA256 签名 xml 文件，并使用此哈希：Quzn98x3PMbSHwbUzaj5f5KOpiH0u8bvmwbbbNkO9Es

我签署了 XML，但它无效，因为我不知道如何输入该哈希。这是我的代码：

public class Firma{

private static final String FOLDER = "C:/ECLIPSE/PRUEBAS_Firma/";
private static final String CERT = "SOLdisP_XXXXX.p12";// "Certificado de
                                                        // dispositivo
private static final String PASS = "xxxxxx";

private static final String DOCUMENT = "C:/ECLIPSE/PRUEBAS_Firma/Ejemplo_TicketBAI_B00000034_B2022_0101_SinFirma.xml";

public static void main(String[] args) throws Exception {
    System.setProperty("org.apache.xml.security.ignoreLineBreaks","true");

    System.out.println(">>>>>>>>> Firmando XML");
    signEpes();
}

private static void signEpes() throws Exception {
    Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new File(DOCUMENT));
    Element elem = doc.getDocumentElement();
    DOMHelper.useIdAsXmlId(elem);

    KeyingDataProvider kdp = new FileSystemKeyStoreKeyingDataProvider("pkcs12",FOLDER + CERT,new FirstCertificateSelector(),new DirectPasswordProvider(PASS),true);
    // politica
    SignaturePolicyInfoProvider policyInfoProvider = new SignaturePolicyInfoProvider() {
        @Override
        public SignaturePolicyBase getSignaturePolicy() {
            return new SignaturePolicyIdentifierProperty(

                    new ObjectIdentifier(
                            "https://www.batuz.eus/fitxategiak/batuz/ticketbai/sinadura_elektronikoaren_zehaztapenak_especificaciones_de_la_firma_electronica_v1_0.pdf",IdentifierType.URI,""),new ByteArrayInputStream(
                            "https://www.batuz.eus/fitxategiak/batuz/ticketbai/sinadura_elektronikoaren_zehaztapenak_especificaciones_de_la_firma_electronica_v1_0.pdf"
                                    .getBytes())

            );
        }
    };

    SignerEPES signer = (SignerEPES) new XadesEpesSigningProfile(kdp,policyInfoProvider).newSigner();

    new Enveloped(signer).sign(elem);

    outputDocument(doc,"Factura_firmada.xml");
}

protected static void outputDocument(Document doc,String fileName) throws Exception {
    TransformerFactory tf = TransformerFactory.newInstance();
    File outDir = ensureOutputDir();
    FileOutputStream out = new FileOutputStream(new File(outDir,fileName));
    tf.newTransformer().transform(new DOMSource(doc),new StreamResult(out));
    out.close();
}

private static File ensureOutputDir() {
    File dir = new File(toPlatformSpecificFilePath(FOLDER));
    dir.mkdir();
    return dir;
}

}

请问，谁能帮帮我？？？ 提前致谢
