Sign SOAP XML using a wsse:SecurityTokenReference
See more XML Digital Signatures Examples
This example signs SOAP XML such that the KeyInfo in the XML Signature is a wsse:SecurityTokenReference to the X.509 certificate embedded elsewhere in the SOAP XML.Chilkat Go Downloads

// 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.
