(Node.js) Generate RSA Public/Private Key

Node.js example code showing how to generate an RSA public/private key.

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

var os = require('os');
if (os.platform() == 'win32') {  
    if (os.arch() == 'ia32') {

    // See Global Unlock Sample for sample code.

    // key sizes ranging from 512 bits to 4096 bits.
    // Note: Starting in Chilkat v9.5.0.49, RSA key sizes can be up to 8192 bits.
    // It takes a considerable amount of time and processing power to generate
    // an 8192-bit key.
