(Node.js) FTPS with Mutual TLS Authentication (TLS Client Certificate)

Demonstrates how to do mutual TLS authentication (using a client certificate from a .pfx/.p12).

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM
