 Product: Sectigo SSL Certificate 

Platform: Node.js 

Overview: 
This guide provides the step-by-step process for installing a Sectigo SSL certificate on a Node.js server. Implementing SSL ensures secure communication between your server and clients by enabling HTTPS. To install a Sectigo SSL certificate in Node.js, you need to use the built-in https module and the fs module to read your certificate files and configure an HTTPS server. The core process involves obtaining your certificate files, placing them on your server, and updating your Node.js application code to use them. 

Audience: 
Developers or system administrators responsible for configuring SSL on Node.js applications. 

Scope: 
This procedure covers installing the SSL certificate files, configuring the Node.js HTTPS server, and verifying the installation. 

Prerequisites

Step-by-Step Installation Guide 

(Use code with caution) Here is an example of the Node.js code: 

   var https = require('https'); 

var fs = require('fs'); 

// Define the options for the HTTPS server, specifying the paths to your files 

   var options = { 

     key: fs.readFileSync('/path/to/private.key'),      // Your private key 

     cert: fs.readFileSync('/path/to/certificate.crt'),    // Your primary certificate 

     ca: fs.readFileSync('/path/to/bundle.ca-bundle')      // Your CA bundle 

   }; 

// Create the HTTPS server 

   https.createServer(options, function (req, res) { 

     res.writeHead(200); 

     res.end("Welcome to Node.js HTTPS Server!\n"); 

   }).listen(443); // Listen on the standard HTTPS port (443) 

console.log('HTTPS server running on port 443'); 

Make sure to replace /path/to/ with the actual file paths on your server 

sudo node https_server.js
