How to Send Encrypted Data with Postman

What Can You Build with Node.js? Encrypt data with crypto-js and decrypt it with the built-in Node.js crypto module. Now we’re ready to send encrypted data from Postman but we don’t have a backend to receive it. I have a REST API that needs to send and receive AES(256) encryption.

_Prerequisite: _Knowledge of JavaScript, Node.js, and basic knowledge of __Postman

Recently, I started interacting with a project’s backend that accepts only encrypted dat — that is, plaintext is converted to  ciphertext before it is sent to the backend. On the backend, the ciphertext is then decrypted back to plaintext. The backend was written with Java, so I thought about how to accomplish this with Node.js.

Since I hadn’t done such a thing before, I had to do some research to see how this was done. Once I discovered what I was looking for, I had to test my findings. And the fastest way to test an API without creating a frontend is with  Postman.

According to __BlazeMeter, Postman_ is a popular API client that makes it easy for developers to create, share, test and document APIs. This is done by allowing users to create and save simple and complex HTTP/s requests, as well as read their responses. The result — more efficient and less tedious work._

Even though I had experience with Postman, I didn’t know how to encrypt data before making a request yet. So, I began another round of research and stumbled upon a tab on Postman called Pre-request Script. As the name implies, it’s a script that runs just before a request is sent.

Decoding Nodejs

The main goal of this blog is to explain the “Architecture of Nodejs” and to know how the Nodejs works behind the scenes. Generally, most of the server-side languages, like PHP, ASP.NET, Ruby, and including Nodejs follows multi-threaded architecture. That means for each client-side request initiates a new thread or even a new process.

Learning JavaScript: Development Environments for JavaScript Programming

One of the nice things about learning JavaScript these days is that there is a plethora of choices for writing and running JavaScript code. In this article, I’m going to describe a few of these environments and show you the environment I’ll be using in this series of articles.

Learning JavaScript: Data Types and Variables

To paraphrase the title of an old computer science textbook, “Algorithms + Data = Programs.” The first step in learning a programming language such as JavaScript is to learn what types of data the language can work with. The second step is to learn how to store that data in variables. In this article I’ll discuss the different types of data you can work with in a JavaScript program and how to create and use variables to store and manipulate that data.
