common library for .net and node js for encryption

Node.js has a common library for encryption called "crypto." This library provides various cryptographic functionalities, including encryption and decryption. The following steps outline the encryption process using the "crypto" library in Node.js:

1. Import the "crypto" module:

const crypto = require('crypto');

1. Create a cipher using an encryption algorithm (e.g., AES):

const algorithm = 'aes-256-cbc';
const key = crypto.randomBytes(32); // Generate a random key
const iv = crypto.randomBytes(16); // Generate a random initialization vector
const cipher = crypto.createCipheriv(algorithm, key, iv);

1. Encode the data to be encrypted into a buffer:

let encryptedData = cipher.update('YOUR_DATA_HERE', 'utf-8', 'hex');
encryptedData += cipher.final('hex');

1. Optionally, you can generate an authentication tag for additional security (for authenticated encryption algorithms):

const authenticationTag = cipher.getAuthTag();

1. Now, the "encryptedData" variable contains the encrypted data, and the "key" and "iv" variables hold the encryption key and initialization vector, respectively. These values are required for decryption.

This outlines the basic steps for encryption using the "crypto" library in Node.js.
