Generating a CSR in Node.js

Generating a CSR in Node.js

Node.js is an open-source cross-platform runtime environment (RE) used for developing server-side web applications. Functioning as an asynchronous event-driven framework, Node.js is specifically designed for constructing scalable network applications. In terms of security, this server-side RE can incorporate an SSL certificate, enabling the utilization of mod tls and consequently facilitating the use of https.createServer for HTTP over TLS connection.

How to Generating a CSR in Node.js

Step 1

To generate a certificate signing request, OpenSSL can be employed. Check its availability in your modpack using the following command:

$ openssl

If there is no such addon, download it using this command:

npm install openssl

After that, use the following command for CSR/RSA private key generation:

openssl req -nodes -newkey rsa:2048 -keyout example_com.key -out example_com.csr

Step 2

Use only alphanumeric characters (English letters and numbers) filling the required fields with the needed information:

  • Common Name (the domain name certificate should be issued for, for Wildcard certificates use *
  • Country (two digit ISO compliant country code)
  • State (or province)
  • City
  • Organization ( Legally registered company name – obligatory for Organization Validation and Extended validation certificates, NA can be used for Domain Validation certificates)
  • Organizational Unit (Department – Additional company information, NA can be used for DV certificates as well)
  • E-mail address

Your CSR will be generated in a .csr file, and the private key will be placed in the .key file.

Copy the generated CSR and proceed with the certificate activation procedure.

After the certificate issuance is completed, use this guide to install it.
