(Node.js) 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.

Install Chilkat for Node.js and Electron using npm at
