我已经签署了一个 XML 文件以使用适当的证券发送，但不知何故，我发送的服务检测到该文件的签名无效（X.509 证书验证没问题）。我一直在寻找是否有可能，一旦我签署了特定的 XML，就可以检索 XML 签署的信息（如解密），以验证我是否使用正确的节点来签署 XML。谁能帮帮我？

Ps.：我仍然有公共和私人证书密钥。

这是我用来签署 XML 元素“infEvento”的代码，然后是 XML 元素。

public XmlDocument retornaEvtsXMLAssinados(X509Certificate2 cert, string MensagemXML)
{            
    XmlDocument xmlDoc = new XmlDocument();

    xmlDoc.LoadXml(MensagemXML);
    XmlNodeList evtsNode = xmlDoc.GetElementsByTagName("evento");

    foreach (XmlElement evtNode in evtsNode)
    {
        RSACryptoServiceProvider key = new System.Security.Cryptography.RSACryptoServiceProvider();
        System.Security.Cryptography.Xml.SignedXml SignedDocument;
        var keyInfo = new System.Security.Cryptography.Xml.KeyInfo();
        keyInfo.AddClause(new KeyInfoX509Data(cert));
        key = (System.Security.Cryptography.RSACryptoServiceProvider)cert.PrivateKey;
        SignedDocument = new System.Security.Cryptography.Xml.SignedXml(evtNode);
        SignedDocument.SigningKey = key;
        SignedDocument.KeyInfo = keyInfo;
        Reference reference = new System.Security.Cryptography.Xml.Reference();
        reference.Uri = "#" + evtNode["infEvento"].Attributes["Id"].Value;
        reference.AddTransform(new XmlDsigEnvelopedSignatureTransform());
        reference.AddTransform(new XmlDsigC14NTransform(false));
        SignedDocument.AddReference(reference);
        SignedDocument.ComputeSignature();
        XmlElement xmlDigitalSignature = SignedDocument.GetXml();
        XmlNode nodeAss = xmlDoc.ImportNode(xmlDigitalSignature, true);
        evtNode.AppendChild(nodeAss);
    }
    return xmlDoc;
}

这是 XML 元素：

这是我目前用于我的一个。在您的情况下可能不需要添加额外的元素，但是以防万一我把它留在那里。

private static void SignXml(XmlDocument doc, X509Certificate2 cert)
{
    var signer = new SignedXmlWithId(doc);

    signer.SigningKey = cert.PrivateKey;
    signer.KeyInfo = new KeyInfo();

    var s = new SecurityTokenReference();
    s.Reference = "uuid-639b0-fc-1";
    s.ValueType = "http://Something.com";
    signer.KeyInfo.AddClause(s);

    signer.SignedInfo.CanonicalizationMethod = SignedXml.XmlDsigExcC14NTransformUrl;
    var bodyRef = new Reference("#ID-00008");
    var messageRef = new Reference("#ID-00004");
    var usernameRef = new Reference("#ID-00001");

    bodyRef.AddTransform(new XmlDsigExcC14NTransform());
    messageRef.AddTransform(new XmlDsigExcC14NTransform());
    usernameRef.AddTransform(new XmlDsigExcC14NTransform());

    signer.AddReference(bodyRef);
    signer.AddReference(messageRef);
    signer.AddReference(usernameRef);

    signer.ComputeSignature();

    var signData = signer.GetXml();

    var nsmgr = new XmlNamespaceManager(doc.NameTable);
    nsmgr.AddNamespace("SOAP-ENV", "http://schemas.xmlsoap.org/soap/envelope/");
    nsmgr.AddNamespace("wsee", "http://stuff.to.add");
    nsmgr.AddNamespace("cwsh", "http://more.stuff.to.add");

    var security = doc.SelectSingleNode("/SOAP-ENV:Envelope/SOAP-ENV:Header/wsee:Security", nsmgr);
    security.AppendChild(doc.ImportNode(signData, true));
}

//Subclass to add namespace when signing
public class SignedXmlWithId : SignedXml
{
    public SignedXmlWithId(XmlDocument xml) : base(xml)
    {
    }

    public SignedXmlWithId(XmlElement xmlElement) : base(xmlElement)
    {
    }

    public override XmlElement GetIdElement(XmlDocument doc, string id)
    {
        // check to see if it's a standard ID reference
        var idElem = base.GetIdElement(doc, id);

        if (idElem == null)
        {
            var nsManager = new XmlNamespaceManager(doc.NameTable);
            nsManager.AddNamespace("wsu",
                "http://wsssecurity.location");

            idElem = doc.SelectSingleNode("//*[@wsu:Id=\"" + id + "\"]", nsManager) as XmlElement;
        }

        return idElem;
    }
}
