How to Generate Hash?

I Try Alot of Things but i Got This Error The Hash is Not Like Calculated Hash :
i tryed :

1- Sign and Calc Hash By SDK
2- Sign and Calc Hash By Code (Manual)
3- Sign and Calc Hash and Replace the Old Hash With the New One By SDK and Manual

all i got same Error.

This is The Signed Invoice i Use : Can Someone Tell me What is The Hash for it and How he did it ?

I Calculate After Sign. i Use last SDK Version 3.3.6 and i Try Emails Before and no one answer or Replay. and i Put the Invoice as Base64 u Can Check it .

Thanx alot

Morning @aymannagy

Thanks for reaching out,

To ensure comprehensive support as usual, can I kindly ask you to mention all the steps that you are followed in order to sign your invoice?

Thanks,
Ibrahem Daoud.

sdk 3.3.6 .

1- Sign the invoice >>>> Generate Hash .

2- Using This Code :

    //private static string GetBase64InvoiceHash(string eInvoiceXml)
    //{


    //    XmlDocument document = new XmlDocument();
    //    document.LoadXml(eInvoiceXml);

    //    //XmlNamespaceManager xmlNamespaceManager = new XmlNamespaceManager(document.NameTable);
    //    //xmlNamespaceManager.AddNamespace("cac", "urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2");
    //    //xmlNamespaceManager.AddNamespace("cbc", "urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2");
    //    //xmlNamespaceManager.AddNamespace("ext", "urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2");


    //    //XmlNode nodeUBLExtension = document.SelectSingleNode(@"*[local-name()='Invoice']//*[local-name()='UBLExtensions']", xmlNamespaceManager);
    //    //nodeUBLExtension.RemoveAll();
    //    //XmlNode parentnodeUBLExtension = nodeUBLExtension.ParentNode;
    //    //parentnodeUBLExtension.RemoveChild(nodeUBLExtension);

    //    //XmlNode nodeQR = document.SelectSingleNode(@"//*[local-name()='AdditionalDocumentReference'][cbc:ID[normalize-space(text()) = 'QR']]", xmlNamespaceManager);
    //    //nodeQR.RemoveAll();
    //    //XmlNode parentnodeQR = nodeQR.ParentNode;
    //    //parentnodeQR.RemoveChild(nodeQR);

    //    //XmlNode nodeSignature = document.SelectSingleNode(@"*[local-name()='Invoice']//*[local-name()='Signature']");
    //    //nodeSignature.RemoveAll();
    //    //XmlNode parentnodeSignature = nodeSignature.ParentNode;
    //    //parentnodeSignature.RemoveChild(nodeSignature);

    //    //foreach (XmlNode node in document)
    //    //{
    //    //    if (node.NodeType == XmlNodeType.XmlDeclaration)
    //    //    {
    //    //        document.RemoveChild(node);
    //    //    }
    //    //}
    //    //System.IO.File.WriteAllText(@"D:\AYman\Output\BeforeSign.txt", document.InnerXml.Replace(" />", "/>"));
    //    StringBuilder output = new();
    //    XmlWriterSettings settings = new()
    //    {
    //        OmitXmlDeclaration = true,
    //        Encoding = Encoding.UTF8,
    //        ConformanceLevel = ConformanceLevel.Auto,
    //        Indent = true
    //    };

    //    using (XmlWriter writer = XmlWriter.Create(output, settings))
    //    {
    //        XmlReader stylesheet = XmlReader.Create(new StringReader(ZatcaDataInvoice));
    //        XmlReader input = XmlReader.Create(new StringReader(document.InnerXml.Replace(" />", "/>")));
    //        input.Read();
    //        XslCompiledTransform transform1 = new();
    //        transform1.Load(stylesheet);
    //        transform1.Transform(input, writer);
    //    }


    //    using MemoryStream stream = new(Encoding.UTF8.GetBytes(output.ToString()));
    //    XmlDsigC14NTransform transform2 = new(false);
    //    transform2.LoadInput(stream);
    //    MemoryStream outputMS = transform2.GetOutput() as MemoryStream;
    //    byte[] hashBytes = HashSha256(Encoding.UTF8.GetString(outputMS.ToArray()));
    //    return Convert.ToBase64String(hashBytes);
    //}

Dear @aymannagy

Based on the invoice you shared the Hash is the first DigestValue in the XML, which in your case is “m8eDhcfHw/Nmt9vBYhGLL+fnFUO3q7VQNW7j3sT5X2E=”.

Thanks A lot . Now I’m Done With Simulation environment how i Move to Production Environment ? is There Sandbox On Production also ??

m8eDhcfHw/Nmt9vBYhGLL+fnFUO3q7VQNW7j3sT5X2E=

But this wrong Hash, because your xml is linearized.
try formatting your XML with indentation before Signing using Zatca eInvoice SDK

You should get

O8n3zNR8ADOtD7YasqNlvU4nSnjj+UARU33sTQOeI0g=

and it accepted by Zatca

I tried to Format the xml its give me this :

and it give me Same Hash :

m8eDhcfHw/Nmt9vBYhGLL+fnFUO3q7VQNW7j3sT5X2E=

Formatting Function is

     static string PrettyXml(string xml)
     {
         var stringBuilder = new StringBuilder();

         var element = XElement.Parse(xml);

         var settings = new XmlWriterSettings();
         settings.OmitXmlDeclaration = true;
         settings.Indent = true;
         settings.NewLineOnAttributes = true;

         using (var xmlWriter = XmlWriter.Create(stringBuilder, settings))
         {
             element.Save(xmlWriter);
         }

         return stringBuilder.ToString();
     }

Did i Do something Wrong ?

Thanks Alot i will work on Your Advice if i Got Problem in B2C but in B2B i just Generate QR and Get the Hash By Xpath .

Make sure you set { PreserveWhitespace = true } on XmlDocument when load xml file content.
