我有这个问题：
我使用 DLL FirmaXadesNet 对 xml 发票进行数字签名，签名起初看起来不错，并且在 Visual Studio 2017 中没有显示错误，
在 xml 文件中创建签名节点后，我将其移动到 xml 的另一个位置。
该文件被发送到验证它的 post 服务，但验证是在 java 中使用 xades4j 完成的，并且显示验证错误：
“com.indra.mmdd.signature.exceptions.ValidateException：xades4j.verification.ReferenceValueException：无法验证引用''”
我不知道这个错误的原因是什么......有什么帮助吗？
我的代码：
XadesService xadesService = new XadesService();
SignatureParameters parametros = new SignatureParameters();
// Política de firma de factura-e 3.1
parametros.SignaturePolicyInfo = new SignaturePolicyInfo();
parametros.SignaturePolicyInfo.PolicyIdentifier = "https://www.dian.gov.co/contratos/facturaelectronica/politicafirma_v1_0.pdf";
parametros.SignaturePolicyInfo.PolicyHash = "Ohixl6upD6av8N7pEvDABhEL6hM=";
parametros.SignaturePolicyInfo.PolicyDigestAlgorithm = FirmaXadesNet.Crypto.DigestMethod.SHA1;
parametros.ElementIdToSign = "";
parametros.ExternalContentUri = "";
parametros.SignaturePackaging = SignaturePackaging.ENVELOPED;
parametros.SignerRole = new FirmaXadesNet.Signature.Parameters.SignerRole();
parametros.SignerRole.ClaimedRoles.Add("supplier");
parametros.DigestMethod = FirmaXadesNet.Crypto.DigestMethod.SHA1;
parametros.SignatureMethod = SignatureMethod.RSAwithSHA1;
parametros.SigningDate = SigningDate;
MemoryStream xmlStream = new MemoryStream();
Stream SignedXmlStream = new MemoryStream();
documentoxml.Save(xmlStream);
xmlStream.Flush();//Adjust this if you want read your data
xmlStream.Position = 0;
using (parametros.Signer = new Signer(certificate))
{
var docFirmado = xadesService.Sign(xmlStream, parametros);
docFirmado.Save(SignedXmlStream);
docFirmado.Save("c:\\temp\\tst.xml");
SignedXmlStream.Flush();
SignedXmlStream.Position = 0;
documentoxml = XDocument.Load(SignedXmlStream);
}
签名创建：
