How to install an SSL certificate on Node.js?
There are three basic steps if you want to install an SSL certificate on Node.js.
1. Download your SSL certificate
The first step to install your SSL certificate on Node.js is to buy one.
There are plenty of websites that you can choose from at the optimum price. The best part is that you have an option to choose from a very wide variety of SSL certificates in the market.
That said, you should purchase SSL certificate which aligns best with your business model. After you have made the purchase, there would be a document verification process by the Certificate Authority.
After the verification is complete, you will receive an email containing:
- Intermediate certificates
- Root certificates
- CA bundle files
2. Create the ‘https_server.js’ file and upload SSL files
In this step, the ‘server.js’ part of the code can be renamed as per your business requirement. For example, it can be renamed as, ‘X.js.’
You can use the following codes to generate the https server, which is the ‘https_server.js’ file here:
#vim https_server.js
var https = require('https');
var 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)
This is the generic code. Of course, you will have to tweak the codes a bit and tailor it as per your business requirement.
You will need to replace the following commands with pathways pertaining to your file:
path/to/private.key
It is the path of your private key file.
path/to/your_domain_name.crt
Here, you will need to enter the path of your SSL certificate file.
path/to/CA_root.crt
Here, you will need to provide the full path of the Certificate Authority-issued root certificate file.
path/to/ca_bundle_certificate
This is the full path of the CA bundle file.
3. Activation of SSL certificate
This is the last step, where you will need to write the code to activate the SSL certificate on the Node.js.
Here is the simple code:
# node https_server.js
Once you run this piece of code, the SSL certificate will be set off on Node.js.
And you are ready to go!
However, just for confirmation, you could use an online SSL checker tool to check if the SSL certificate has indeed been activated.
