(AutoIt) Create XML Signature with KeyInfo / X509Data / X509IssuerSerialThis example demonstrates how to create an XML Digital Signature where the KeyInfo element contains an X509Data element,
; This example requires the Chilkat API to have been previously unlocked. ; See Global Unlock Sample for sample code. ; To begin, we'll need a PFX containing a certificate and private key, and the SOAP XML to be signed. ; Chilkat provides sample data at chilkatsoft.com and chilkatdownload.com, and our first step is to download. ; ------------------------------------------------------------------------- ; Step 1: Get the SOAP XML to be signed. ; $oSbXml = ObjCreate("Chilkat.StringBuilder") $oHttp = ObjCreate("Chilkat.Http") Local $bSuccess = $oHttp.QuickGetSb("https://www.chilkatsoft.com/exampleData/soapToSign.xml",$oSbXml) If ($bSuccess <> True) Then ConsoleWrite($oHttp.LastErrorText & @CRLF) Exit EndIf ; The SOAP XML contains this: ; <?xml version="1.0" encoding="UTF-8" standalone="no" ?> ; <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> ; <SOAP-ENV:Header> ; <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" SOAP-ENV:mustUnderstand="1"></wsse:Security> ; </SOAP-ENV:Header> ; <SOAP-ENV:Body xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12" SOAP-SEC:id="Body"> ; <z:FooBar xmlns:z="http://example.com" /> ; </SOAP-ENV:Body> ; </SOAP-ENV:Envelope> ; ------------------------------------------------------------------------- ; Step 2: Get the test certificate and private key stored in a .pfx ; $oPfxData = ObjCreate("Chilkat.BinData") $bSuccess = $oHttp.QuickGetBd("https://chilkatdownload.com/example_data/testcertificate.pfx",$oPfxData) If ($bSuccess <> True) Then ConsoleWrite($oHttp.LastErrorText & @CRLF) Exit EndIf $oPfx = ObjCreate("Chilkat.Pfx") Local $sPassword = "test" $bSuccess = $oPfx.LoadPfxEncoded($oPfxData.GetEncoded("base64"),"base64",$sPassword) If ($bSuccess <> True) Then ConsoleWrite($oPfx.LastErrorText & @CRLF) Exit EndIf ; ------------------------------------------------------------------------- ; Step 3: Get the certificate from the PFX. ; Local $oCert = $oPfx.GetCert(0) If ($oPfx.LastMethodSuccess <> True) Then ConsoleWrite($oPfx.LastErrorText & @CRLF) Exit EndIf ; Prepare for signing... $oGen = ObjCreate("Chilkat.XmlDSigGen") ; Indicate where the Signature will be inserted. $oGen.SigLocation = "SOAP-ENV:Envelope|SOAP-ENV:Header|wsse:Security" ; Add a reference to the fragment of the XML to be signed. ; Note: "Body" refers to the XML element having an "id" equal to "Body", where "id" is case insensitive ; and where any namespace might qualify the attribute. In this case, the SOAP-ENV:Body fragment is signed ; NOT because the tag = "Body", but because it has SOAP-SEC:id="Body" $oGen.AddSameDocRef("Body","sha1","EXCL_C14N","","") ; (You can read about the SignedInfoPrefixList in the online reference documentation. It's optional..) $oGen.SignedInfoPrefixList = "wsse SOAP-ENV" ; Provide the private key for signing via the certificate, and indicate that ; we want only the Issuer's DN and serial number of the certificate embedded in the KeyInfo. $oGen.KeyInfoType = "X509Data" $oGen.X509Type = "IssuerSerial" ; Note: Because our certificate was loaded from a PFX which also contained the private key, ; Chilkat automatically knows and has the private key associated with the certificate. ; We set bUsePrivateKey to tell the SetX509Cert method to automatically use the private key ; associated with the certificate for signing. If, for example, we obtained the certificate ; by loading from a .cer file, then we would not already have the associated private key. ; In that case, the application could explicitly load the cert's private key from some ; other source, such as a .key, .pem, etc. and then call gen.SetPrivateKey. Local $bUsePrivateKey = True $bSuccess = $oGen.SetX509Cert($oCert,$bUsePrivateKey) If ($bSuccess <> True) Then ConsoleWrite($oGen.LastErrorText & @CRLF) Exit EndIf ; Everything's specified. Now create and insert the Signature $bSuccess = $oGen.CreateXmlDSigSb($oSbXml) If ($bSuccess <> True) Then ConsoleWrite($oGen.LastErrorText & @CRLF) Exit EndIf ; Examine the XML with the digital signature inserted ConsoleWrite($oSbXml.GetAsString() & @CRLF) ; Here is the actual output. A pretty-printed version of the output is shown below, but the addition of whitespace ; in the XML invalidates the signature. ; <?xml version="1.0" encoding="UTF-8" standalone="no" ?> ; <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> ; <SOAP-ENV:Header> ; <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" SOAP-ENV:mustUnderstand="1"><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#"><InclusiveNamespaces xmlns="http://www.w3.org/2001/10/xml-exc-c14n#" PrefixList="wsse SOAP-ENV"/></ds:CanonicalizationMethod><ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256"/><ds:Reference URI="#Body"><ds:Transforms><ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/></ds:Transforms><ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/><ds:DigestValue>PIiVPpuMc1jGpWaL8ftzTOcc4gc=</ds:DigestValue></ds:Reference></ds:SignedInfo><ds:SignatureValue>Rlta8LplnFH0q8L+UeVmh4Smdn6oVETi4RoUmpT/KQX3RNAIOdCVE3b7gjmx5+3vp3DhjphOsZvW6dXzkI46xt9pD5otp3b/ZppGqKzltggo9gyQtPvJ8ltJZqVKYOGo5uElRFF/xm/zcx5Y3E14t+LYVSlv2lbem/zZ5zQ7ai8DmGD33id7nGu+MXVwb3kGkJFYoB/GOXtwsep+bcilMglTp8/7SBfBaVFKxWVBp4N2NW7bGlyDct8FaCk9hXQDNm/kqne9GU87tgh8/rbsFCYgyqIRMIvMPvhRWr2EKdEKyLtlZ8w0KYJYpgsf4T7SDghemzXkJoJPrfUQmHudIw==</ds:SignatureValue><ds:KeyInfo><ds:X509Data><ds:X509IssuerSerial><ds:X509IssuerName>CN=Test Company, C=AU, ST=Some-State, O=Internet Widgits Pty Ltd</ds:X509IssuerName><ds:X509SerialNumber>00</ds:X509SerialNumber></ds:X509IssuerSerial></ds:X509Data></ds:KeyInfo></ds:Signature></wsse:Security> ; </SOAP-ENV:Header> ; <SOAP-ENV:Body xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12" SOAP-SEC:id="Body"> ; <z:FooBar xmlns:z="http://example.com" /> ; </SOAP-ENV:Body> ; </SOAP-ENV:Envelope> ; ---------------------------------------------------------------- ; Pretty-printed output (invalidates the signature) ; This makes it easier to see the X509IssuerSerial contained within the KeyInfo. ; <?xml version="1.0" encoding="UTF-8" standalone="no" ?> ; <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> ; <SOAP-ENV:Header> ; <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" SOAP-ENV:mustUnderstand="1"> ; <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#"> ; <InclusiveNamespaces xmlns="http://www.w3.org/2001/10/xml-exc-c14n#" PrefixList="wsse SOAP-ENV" /> ; </ds:CanonicalizationMethod> ; <ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256" /> ; <ds:Reference URI="#Body"> ; <ds:Transforms> ; <ds:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#" /> ; </ds:Transforms> ; <ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1" /> ; <ds:DigestValue>PIiVPpuMc1jGpWaL8ftzTOcc4gc=</ds:DigestValue> ; </ds:Reference> ; </ds:SignedInfo> ; <ds:SignatureValue>Rlta8LplnFH0q8L+UeVmh4Smdn6oVETi4RoUmpT/KQX3RNAIOdCVE3b7gjmx5+3vp3DhjphOsZvW6dXzkI46xt9pD5otp3b/ZppGqKzltggo9gyQtPvJ8ltJZqVKYOGo5uElRFF/xm/zcx5Y3E14t+LYVSlv2lbem/zZ5zQ7ai8DmGD33id7nGu+MXVwb3kGkJFYoB/GOXtwsep+bcilMglTp8/7SBfBaVFKxWVBp4N2NW7bGlyDct8FaCk9hXQDNm/kqne9GU87tgh8/rbsFCYgyqIRMIvMPvhRWr2EKdEKyLtlZ8w0KYJYpgsf4T7SDghemzXkJoJPrfUQmHudIw==</ds:SignatureValue> ; <ds:KeyInfo> ; <ds:X509Data> ; <ds:X509IssuerSerial> ; <ds:X509IssuerName>CN=Test Company, C=AU, ST=Some-State, O=Internet Widgits Pty Ltd</ds:X509IssuerName> ; <ds:X509SerialNumber>00</ds:X509SerialNumber> ; </ds:X509IssuerSerial> ; </ds:X509Data> ; </ds:KeyInfo> ; </ds:Signature> ; </wsse:Security> ; </SOAP-ENV:Header> ; <SOAP-ENV:Body xmlns:SOAP-SEC="http://schemas.xmlsoap.org/soap/security/2000-12" SOAP-SEC:id="Body"> ; <z:FooBar xmlns:z="http://example.com" /> ; </SOAP-ENV:Body> ; </SOAP-ENV:Envelope> ; |
