How to set up a Node.js SSL Certificate? [Complete Guide]

Node.js is a free, open-sourced server environment that runs on various operating systems such as Windows, Linux, Unix, Mac, OS X and all operating systems. Node.js uses Java scripts for function on the server and how to set up a Node.js SSL Certificate?Now let’s go straight to the purpose you’re here: Installing an SSL certificate on Node.js. The Process flow of installing an SSL certificate on Node.js is pretty simple and easy to do. This process can be made into three steps.

Methods to Set up Node.js SSL Certificate

Here are 3 methods to set up Node.js SSL Certificate

Method 1: Download the Node.js SSL Certificate

Firstly, start with the process only if you have purchased an SSL certificate and completed the entire process ultimately. If you haven’t, you must buy one. And if you’re looking to save your hard-earned money, there are some really good and cheap Comodo SSL certificates out there. Once you complete the order process and the Certificate authority verifies your documents, they will send the SSL Certificate files via email, including the SSL Certificate, Intermediate and Root Certificate, and CA bundle Files.If the CA Bundle files are missing, you can download them from the Certificate Authority’s official website.

You will have to follow these to proceed to the next step.

1. Primary certificate for your domain.
2. Root certificate.
3. The CA bundle file is with the intermediate and root certificates.
4. Your private key.

Following this, you can activate the Node.js SSL Certificate.

Method 2: Create a https_server.js File and Upload SSL files

Here, you can rename “Server.js” as you wish, and the following values will help create your HTTP server, the https_server.js file. #vim https_server.js

var https = require(‘https’);

ar fs = require(‘fs’);

var https_options = {

key: fs.readFileSync(“/path/to/private.key”),

cert: fs.readFileSync(“/path/to/your_domain_name.crt”),

ca: [

fs.readFileSync(‘path/to/CA_root.crt’),

fs.readFileSync(‘path/to/ca_bundle_certificate.crt’)

]

};

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

res.writeHead(200);

res.end(“Welcome to Node.js HTTPS Servern”);

}).listen(8443)

In the above, replace the previous text with bold with the following.

1. path/to/private.key – Your private key file’s path.
2. path/to/your_domain_name.crt – Enter your SSL certificate file’s path.
3. path/to/CA_root.crt – Provide the CA root certificate file’s full path.
4. Path/to/ca_bundle_certificate – This is the full path of your uploaded CA bundle file.

Following this, you can activate Node.js SSL Certificate.

Method 3: Activate Node.js SSL Certificate

Operating the following command will help you to launch the Node.js application.

# node https_server.js

Once you run this desired command, your SSL Certificate will be active on Node.js.

You can also check whether your desired certificate has been installed using an online SSL checker tool.

Following this method, you can activate Node.js SSL Certificate.

Generate a CSR code in Node.js

To generate the CSR, you are going to use the OpenSSL utility. Usually, OpenSSL should be and will be available on your server and Node.js SSL Certificate.

Alternatively, you can get OpenSSL with the following commands below:

• sudo apt-get install OpenSSL
• sudo yum install OpenSSL

1. Firstly, Run the below command to start the CSR generation process: OpenSSL req -new -newkey rsa:2048 -nodes -keyout yourdomain. key -out your domain.CS
2. Secondly, Replace your domain with the domain name you want to secure

Your domain. the key is your private key

Your domain.CSR is your CSR code.

3. Next, provide the required details. Please fill in the fields below:

Common name: specify the fully qualified domain name you want to desire to assign your SSL Certificate (ex: ssldragon.com). Suppose you bought a Wildcard Certificate, including an asterisk in front of the domain name (ex: *.ssldragon.com).

City: enter the city name where your desired business is officially registered (ex: San Jose)

State: enter the state name where your respected organization or company is located (ex: Maharastra)

Country: enter the two-letter country name of your organization (ex: US)

Organization: type your organization’s official full name (ex: GPI Holding LLC). For validating the certification (DV) Certificates, type NA instead.

Organizational Unit: You should specify the unit responsible for SSL management (ex: IT or Web Administration). If you have a DV certificate, put it NA instead

Email Address: this is an optional field. You can also leave it blank.

Challenge Password: It is another optional field. Leaving this field bank is recommended because the challenge password is an obsolete attribute.

Your CSR Code is ready to use. By default, it resides in yourdomain,csr. You can also open it with any desired text editor such as Notepad. When you are applying for your certificate, please include the full CSR text, including the —-BEGIN CERTIFICATE REQUEST—– and —–END CERTIFICATE REQUEST—– tags.

Along with the CSR, the OpenSSL utility will modify your desired private key (yourdomain. key). but Save and store it in a safe place. You will need it during the SSL configuration and Node.js SSL Certificate.

Node.js History and Versions

The original author of Node.js is Mr. Ryan Dahl, an American software engineer.

Dahl’s inspiration to create Node.js SSL Certificate came up after seeing a file upload progress bar on Flickr. At first, Dahl named its project Web.js because it was just an alternative word for the apache.

After that, when the respective project grew beyond the desired server library into extensive framework, then Dhal named it Node.js.

At Below you will find the latest Node.js releases, still receiving support.

1. 6.x (Boron) – It was released in 2016, and it is currently at the end of its long-term and long-lasting support, with the maintenance ending in April 2019
2. 8.x (Carbon) – It was released in 2017, it has its active support till April 2019 and maintenance support until December 2019
3. 10.x (Dubnium) – It was released in 2018, it has its active support until April 2020 and maintenance support until April 2021.

This was the Node.js SSL Certificate history.
