(PHP ActiveX) Create XML Signature using Java KeyStore (.jks)Demonstrates how to create an XML digital signature using a certificate and private key from a Java KeyStore (.jks)
<?php // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // The SOAP XML to be signed in this example contains the following: // <?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> // // Build the XML to sign. // Use this online tool to generate the code from sample XML: // Generate Code to Create XML // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Xml') $xml = new COM("Chilkat.Xml"); $xml->Tag = 'SOAP-ENV:Envelope'; $xml->AddAttribute('xmlns:SOAP-ENV','http://schemas.xmlsoap.org/soap/envelope/'); $xml->UpdateAttrAt('SOAP-ENV:Header|wsse:Security',1,'xmlns:wsse','http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd'); $xml->UpdateAttrAt('SOAP-ENV:Header|wsse:Security',1,'SOAP-ENV:mustUnderstand','1'); $xml->UpdateAttrAt('SOAP-ENV:Body',1,'xmlns:SOAP-SEC','http://schemas.xmlsoap.org/soap/security/2000-12'); $xml->UpdateAttrAt('SOAP-ENV:Body',1,'SOAP-SEC:id','Body'); $xml->UpdateAttrAt('SOAP-ENV:Body|z:FooBar',1,'xmlns:z','http://example.com'); // Load a JavaKeyStore file containing the certificate + private key. // For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JavaKeyStore') $jks = new COM("Chilkat.JavaKeyStore"); $password = 'secret'; $success = $jks->LoadFile($password,'qa_data/jks/test_secret.jks'); if ($success != 1) { print $jks->LastErrorText .
