; 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>
;

; Note: Because our certificate was loaded from a JKS which also contained the private key,

; associated with the certificate for signing.
