(C#) Calculate HRMC IRMarkDemonstrates how to calculate an IRmark for an HMRC GovTalkMessage XML document.
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // First build a sample (but incomplete) GovTalkMessage. // You can replace this code with a call to LoadXml or LoadXmlFile.. // // Note: The online tool at https://tools.chilkat.io/xmlCreate.cshtml // can be used to generate XML code that creates a given XML document. Chilkat.Xml xml = new Chilkat.Xml(); xml.Tag = "GovTalkMessage"; xml.AddAttribute("xmlns","http://www.govtalk.gov.uk/CM/envelope"); xml.UpdateAttrAt("Body|Message",true,"xmlns","urn:g3.ge:dea:call:SendDocument:v1"); xml.UpdateChildContent("Body|Message","................"); // This is the XML created: // <?xml version="1.0" encoding="utf-8" ?> // <GovTalkMessage xmlns="http://www.govtalk.gov.uk/CM/envelope"> // <Body> // <Message xmlns="urn:g3.ge:dea:call:SendDocument:v1">................</Message> // </Body> // </GovTalkMessage> Debug.WriteLine(xml.GetXml()); // Canonicalize the XML (using C14N) Chilkat.XmlDSig xdsig = new Chilkat.XmlDSig(); bool withComments = false; string canonXml = xdsig.CanonicalizeXml(xml.GetXml(),"C14N",withComments); // Return the base64 SHA-1 HASH of the canonical XML. Chilkat.Crypt2 crypt = new Chilkat.Crypt2(); crypt.HashAlgorithm = "sha1"; crypt.EncodingMode = "base64"; string irmark = crypt.HashStringENC(canonXml); Debug.WriteLine("IRMark = " + irmark); |
