![]() ![]() You can also encrypt and decrypt streams by using the crypto module, as shown in the following example:Ĭrpyto-stream.js const crypto = require ( 'crypto' ) const fs = require ( 'fs' ) const algorithm = 'aes-256-ctr' const secretKey = 'vOVH6sdmpNWjRRIqCc7rdxs01lwHzfr3' const iv = crypto. log (text ) // Hello World! Encrypt and decrypt streams ![]() Let us create the crypto.js file in the project's root directory and define our encryption and decryption functions as shown below:Ĭrpyto.js const crypto = require ( 'crypto' ) const algorithm = 'aes-256-ctr' const secretKey = 'vOVH6sdmpNWjRRIqCc7rdxs01lwHzfr3' const encrypt = text => const text = decrypt (hash )Ĭonsole. However, you can install it by executing the following command: $ npm install crypto -save But if you have manually installed Node.js, crypto may not be shipped with it. ![]() Make sure that you have already installed Node.js on your machine before issuing the above command.īy default, the crypto module is already included in pre-built Node.js binaries. The above command will create a new package.json file in the root directory. Now execute the following command to initialize a new Node.js project: $ npm init -y Create a new projectĬreate a new directory in your local file system and switch to it by typing the following: $ mkdir crypto & cd crypto Here is a good discussion on StackOverflow for choosing the correct AES encryption mode. I'll show you how to encrypt data with a secret key and then decrypt it using the same secret key when required.įor the sake of simplicity, I shall use AES (Advanced Encryption System) algorithm CTR encryption mode. In this article, you'll learn how to use Node.js crypto module to perform cryptographic operations on data. Spring Cloud Config Server - Symmetric Encryption and Decryption. ![]()
