Jasypt Spring Boot - Javascript

Jasypt Spring Boot is a library that simplifies the integration of Jasypt with Spring Boot applications. Jasypt is a Java library that provides easy encryption and decryption of text, using strong encryption algorithms.

In this tutorial, we will explore how to use Jasypt Spring Boot in a Javascript application.

Prerequisites

Before we can start, we need to ensure that our environment is set up correctly. We will need:

• A Javascript application
• The Jasypt Javascript Library
• A Jasypt encryption key

Installation

To use Jasypt in our Javascript application, we need to install the Jasypt Javascript library. We can do this using npm:

npm install jasypt -S

Next, we will need to include the library in our Javascript code:

const jasypt = require('jasypt');

Usage

Using Jasypt in our Javascript application is straightforward. We can encrypt and decrypt using the jasypt object:

// Set up the Jasypt object
const jasypt = require('jasypt');
const cryptor = new jasypt.Cryptor('encryptionKey');

// Encrypt
const plaintext = 'My secret message';
const ciphertext = cryptor.encrypt(plaintext);

// Decrypt
const decryptedText = cryptor.decrypt(ciphertext);

Note that we need to provide the Jasypt encryption key when setting up the Cryptor object. If we don't provide a key, Jasypt will generate a random one for us.

Conclusion

Jasypt Spring Boot makes it easy to integrate Jasypt with Spring Boot applications. The Jasypt Javascript library provides the same functionality for Javascript applications. Using Jasypt, we can easily encrypt and decrypt sensitive information in our applications, providing an additional layer of security.

In this tutorial, we learned how to use Jasypt in a Javascript application. We installed the Jasypt Javascript library and used it to encrypt and decrypt text.
