Summary: Learn how to perform RSA encryption in JavaScript and decryption in Java with a step-by-step example. Explore the interoperability between the two languages for secure data transmission.
---

RSA encryption is a fundamental cryptographic technique widely used for securing data transmission over networks. Implementing RSA encryption and decryption across different programming languages like JavaScript and Java can be essential for building robust and interoperable systems. In this guide, we'll walk through an example of encrypting data in JavaScript using RSA and decrypting it in Java.

Step 1: RSA Encryption in JavaScript

First, let's perform RSA encryption in JavaScript using a library like jsencrypt. You can include this library in your project using npm or directly via CDN.
