(JavaScript) Create EBICS Signature (XMLDSIG)
Demonstrates how to create an EBICS signature. (EBICS is the Electronic Banking Internet
Communication Standard)Note: This example requires Chilkat v11.0.0 or greater.
var success = false;
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// This is the sample XML to be signed:
