Как проверить подпись X509Certificate2 в XML-файле? [закрыто] ⇐ C#

[Anonymous]

Я пытаюсь проверить подпись XML-файла (электронного счета со стандартами UBL). Подпись в файле является лишь образцом и недействительна. Я просто хочу узнать, как проверить подпись.
Ошибка:
System.Security.Cryptography.CryptographicException: SignatureDescription could not be created for the signature algorithm supplied.
at System.Security.Cryptography.Xml.SignedXml.CheckSignedInfo(AsymmetricAlgorithm key)
at System.Security.Cryptography.Xml.SignedXml.CheckSignature(AsymmetricAlgorithm key)
at System.Security.Cryptography.Xml.SignedXml.CheckSignature(X509Certificate2 certificate, Boolean verifySignatureOnly)
at TestClass.Validate(TextReader textReader)

Мой код проверки:
public static bool Validate(string XmlFilePath)
{
using var textReader = new StreamReader(XmlFilePath);
return Validate(textReader);
}

public static bool Validate(TextReader textReader) // A StreamReader or StringReader containing the XML to validate
{
//Create [Doc]
#region

var Doc = new XmlDocument();
Doc.PreserveWhitespace = true;
Doc.Load(textReader);

#endregion

//Create [Namespaces]
#region

var Namespaces = new XmlNamespaceManager(Doc.NameTable);

//IDictionary localNamespaces = null;
var Navigator = Doc.CreateNavigator();
while (Navigator.MoveToFollowing(XPathNodeType.Element))
{
var LocalNamespaces = Navigator.GetNamespacesInScope(XmlNamespaceScope.Local);
foreach (var localNamespace in LocalNamespaces)
{
var Prefix = localNamespace.Key;
if (string.IsNullOrEmpty(Prefix))
{
Prefix = "tst";
}

Namespaces.AddNamespace(Prefix, localNamespace.Value);
}
}

#endregion

//Get [Certificate_Base64]
var Certificate_Base64 = Doc.DocumentElement.SelectSingleNode("ext:UBLExtensions/ext:UBLExtension/ext:ExtensionContent/ds:Signature/ds:KeyInfo/ds:X509Data/ds:X509Certificate", Namespaces).InnerText;

//Create [Certificate]
var Certificate = new X509Certificate2(Convert.FromBase64String(Certificate_Base64));

var SignedDoc = new SignedXml(Doc);
var Result = SignedDoc.CheckSignature(Certificate, true);
return Result;
}

Исходный XML-файл слишком велик для включения, и его изменение приведет к аннулированию подписи. .NET Скрипка. .NET Fiddle, включающий упрощенную версию XML с опущенным двоичным вложением. Это воспроизводит проблему, но, конечно, подпись будет недействительной:
public static void Test()
{
using var reader = new StringReader(GetXml());
Validate(reader);
}

static string GetXml() =>
