(VB.NET UWP/WinRT) 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)

' 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

Dim xml As New Chilkat.Xml
xml.Tag = "SOAP-ENV:Envelope"
xml.AddAttribute("xmlns:SOAP-ENV","http://schemas.xmlsoap.org/soap/envelope/")

' we want the base64 of the certificate embedded in the KeyInfo.

gen.X509Type = "Certificate"

' Note: Because our certificate was loaded from a JKS 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.
Dim bUsePrivateKey As Boolean = True

Dim sbXml As New Chilkat.StringBuilder
