(Node.js) Transition from RandomizeKey to GenRandomBytesENC

Provides instructions for replacing deprecated RandomizeKey method calls with GenRandomBytesENC.

Note: This example requires Chilkat v11.0.0 or greater.

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

    // ------------------------------------------------------------------------
    // Do the equivalent using GenRandomBytesENC followed by SetEncodedKey
