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 Classic ASP Downloads

' To begin, we'll need a PFX containing a certificate and private key, and the SOAP XML to be signed.
