begin
//  This example requires the Chilkat Crypt API to have been previously unlocked.
//  See Unlock Chilkat Crypt for sample code.

//  An HTTP SOAP request is an HTTP request where the SOAP XML composes the body.
//  This example demonstrates how to add a WS-Security header such as the following:
// 
//  <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="SecurityToken-6138db82-5a4c-4bf7-915f-af7a10d9ae96">
//    <wsse:Username>user</wsse:Username>
//    <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">CBb7a2itQDgxVkqYnFtggUxtuqk=</wsse:Password>
//    <wsse:Nonce>5ABcqPZWb6ImI2E6tob8MQ==</wsse:Nonce>
//    <wsu:Created>2010-06-08T07:26:50Z</wsu:Created>
//  </wsse:UsernameToken>
// 

//  First build some simple SOAP XML that has some header and body.
xml := CkXml_Create();
CkXml_putTag(xml,'env:Envelope');
CkXml_AddAttribute(xml,'xmlns:env','http://www.w3.org/2003/05/soap-envelope');
CkXml_UpdateAttrAt(xml,'env:Header|n:alertcontrol',True,'xmlns:n','http://example.org/alertcontrol');
CkXml_UpdateChildContent(xml,'env:Header|n:alertcontrol|n:priority','1');
CkXml_UpdateChildContent(xml,'env:Header|n:alertcontrol|n:expires','2001-06-22T14:00:00-05:00');
CkXml_UpdateAttrAt(xml,'env:Body|m:alert',True,'xmlns:m','http://example.org/alert');
CkXml_UpdateChildContent(xml,'env:Body|m:alert|m:msg','Pick up Mary at school at 2pm');
Memo1.Lines.Add(CkXml__getXml(xml));
Memo1.Lines.Add('----');

//  The following SOAP XML is built:

//  	<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
//  	 <env:Header>
//  	  <n:alertcontrol xmlns:n="http://example.org/alertcontrol">
//  	   <n:priority>1</n:priority>
//  	   <n:expires>2001-06-22T14:00:00-05:00</n:expires>
//  	  </n:alertcontrol>
//  	 </env:Header>
//  	 <env:Body>
//  	  <m:alert xmlns:m="http://example.org/alert">
//  	   <m:msg>Pick up Mary at school at 2pm</m:msg>
//  	  </m:alert>
//  	 </env:Body>
//  	</env:Envelope>
// 

//  Now build the WSSE XML housing that we'll insert into the above SOAP XML at the end.

//  	<wsse:Security>
//  	  <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="WSU_ID">
//  	    <wsse:Username>USERNAME</wsse:Username>
//  	    <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest">PASSWORD_DIGEST</wsse:Password>
//  	    <wsse:Nonce>NONCE</wsse:Nonce>
//  	    <wsu:Created>CREATED</wsu:Created>
//  	  </wsse:UsernameToken>
//  	</wsse:Security>

wsse := CkXml_Create();
CkXml_putTag(wsse,'wsse:Security');
CkXml_UpdateAttrAt(wsse,'wsse:UsernameToken',True,'xmlns:wsu','http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd');
CkXml_UpdateAttrAt(wsse,'wsse:UsernameToken',True,'wsu:Id','WSU_ID');
CkXml_UpdateChildContent(wsse,'wsse:UsernameToken|wsse:Username','USERNAME');
CkXml_UpdateAttrAt(wsse,'wsse:UsernameToken|wsse:Password',True,'Type','http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest');
CkXml_UpdateChildContent(wsse,'wsse:UsernameToken|wsse:Password','PASSWORD_DIGEST');
CkXml_UpdateChildContent(wsse,'wsse:UsernameToken|wsse:Nonce','NONCE');
CkXml_UpdateChildContent(wsse,'wsse:UsernameToken|wsu:Created','CREATED');
Memo1.Lines.Add(CkXml__getXml(wsse));
Memo1.Lines.Add('----');

//  Insert the wsse:Security XML into the existing SOAP header:
xHeader := CkXml_GetChildWithTag(xml,'env:Header');
CkXml_AddChildTree(xHeader,wsse);
CkXml_Dispose(xHeader);

//  Now show the SOAP XML with the wsse:Security header added:
Memo1.Lines.Add(CkXml__getXml(xml));
Memo1.Lines.Add('----');

//  Now our XML looks like this:
//  	<env:Envelope xmlns:env="http://www.w3.org/2003/05/soap-envelope">
//  	    <env:Header>
//  	        <n:alertcontrol xmlns:n="http://example.org/alertcontrol">

//  	            <n:expires>2001-06-22T14:00:00-05:00</n:expires>
//  	        </n:alertcontrol>
//  	        <wsse:Security>
//  	            <wsse:UsernameToken xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" wsu:Id="WSU_ID">
//  	                <wsse:Username>USERNAME</wsse:Username>

//  	                <wsse:Nonce>NONCE</wsse:Nonce>
//  	                <wsu:Created>CREATED</wsu:Created>
//  	            </wsse:UsernameToken>
//  	        </wsse:Security>
//  	    </env:Header>
//  	    <env:Body>
//  	        <m:alert xmlns:m="http://example.org/alert">
