(Visual FoxPro) IPS MX Signature - Digitally Sign MX Document

See more XML Digital Signatures Examples

Demonstrates how to digitally sign ISO 20022 SWIFT MX messages.

Note: This example requires Chilkat v9.5.0.89 or later. Additional internal functionality was added to auto-recognize SWIFT MX messages and do what is appropriate to satisfy the SWIFT MX specifications.

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

lnSuccess = 1

* First create the XML to be signed, or load it from a file, or a string,

* To load XML from a file:
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Xml')
loXmlToSign = CreateObject('Chilkat.Xml')
lnSuccess = loXmlToSign.LoadXmlFile("c:/someDir/mx_document.xml")

* Or to load XML from a string
lnSuccess = loXmlToSign.LoadXml("...")

* Or create the XML directly.
loXmlToSign.Clear()

* Use this online tool to generate code from sample XML:
