(AutoIt) Create IRS MeF Login Service Request MessageThis example demonstrates how to create a digitally signed Login Service Request Message. This example used the documentation at https://www.irs.gov/pub/irs-utl/mef-doc-stp_ref_guide.pdf as a guide. It creates signed XML as specified in section 4.1.1 found in Section 4: Example A2A Web Service Messages.
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. ; -------------------------------------------------------------------------------- ; Also see Chilkat's Online WSDL Code Generator ; to generate code and SOAP Request and Response XML for each operation in a WSDL. ; -------------------------------------------------------------------------------- ; The goal of this example is to create signed SOAP XML such as the following: ; <?xml version="1.0" encoding="UTF-8"?> ; <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> ; <SOAP-ENV:Header> ; <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> ; <wsse:BinarySecurityToken ; xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" ; EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" ; ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3" ; wsu:Id="CertId-1673181727">MIIHab...n71P</wsse:BinarySecurityToken> ; <ds:Signature xmlns:ds="http://www.w3.org/2000/09/xmldsig#"> ; <ds:SignedInfo> ; <ds:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> ; <ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256"/> ; <ds:Reference URI="#id-1214941501"> ; <ds:Transforms> ; <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> ; </ds:Transforms> ; <ds:DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/> ; <ds:DigestValue>abcdefghijkLMNOPQRSTUVwxyz012345Em0o3VEOTck=</ds:DigestValue> ; </ds:Reference> ; <ds:Reference URI="#id-1871558655"> ; <ds:Transforms> ; <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> ; </ds:Transforms> ; <ds:DigestMethod Algorithm="http://www.w3.org/2001/04/xmlenc#sha256"/> ; <ds:DigestValue>abcdefghijkLMNOPQRSTUVwxyz012345Xm5ViA+royg=</ds:DigestValue> ; </ds:Reference> ; </ds:SignedInfo> ; <ds:SignatureValue>abcd...5Nbw==</ds:SignatureValue> ; <ds:KeyInfo Id="KeyId-256137097"> ; <wsse:SecurityTokenReference xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="STRId-1862925355"> ; <wsse:Reference URI="#CertId-1673181727" ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3"/> ; </wsse:SecurityTokenReference> ; </ds:KeyInfo> ; </ds:Signature> ; </wsse:Security> ; <ns1:MeFHeader xmlns:ns1="http://www.irs.gov/a2a/mef/MeFHeader.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="id-1214941501"> ; <ns1:MessageID>12345202018200000234</ns1:MessageID> ; <ns1:Action>Login</ns1:Action> ; <ns1:MessageTs>2020-06-30T15:25:42.678Z</ns1:MessageTs> ; <ns1:ETIN>12345</ns1:ETIN> ; <ns1:SessionKeyCd>Y</ns1:SessionKeyCd> ; <ns1:TestCd>P</ns1:TestCd> ; <ns1:AppSysID>65432190</ns1:AppSysID> ; <ns1:WSDLVersionNum>10.3</ns1:WSDLVersionNum> ; <ns1:ClientSoftwareTxt>SOATest</ns1:ClientSoftwareTxt> ; </ns1:MeFHeader> ; </SOAP-ENV:Header> ; <SOAP-ENV:Body xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="id-1871558655"> ; <LoginRequest xmlns="http://www.irs.gov/a2a/mef/MeFMSIServices.xsd"/> ; </SOAP-ENV:Body> ; </SOAP-ENV:Envelope> ; ------------------------------------------------------------------------------------------- ; First, let's load the certificate + private key to be used for signing (from a PFX). ; (It is also possible to use certificates installed on a Windows system, or from other file formats..) $oPfx = ObjCreate("Chilkat_9_5_0.Pfx") Local $bSuccess = $oPfx.LoadPfxFile("qa_data/pfx/cert_test123.pfx","test123") If ($bSuccess <> True) Then ConsoleWrite($oPfx.LastErrorText & @CRLF) Exit EndIf ; We'll be needing the X.509 signing cert as base64 for the BinarySecurityToken, so let's get it now.. ; The certificate having the private key should be the 1st in the PFX.
