nodejs如何利用3DES进行加密解密，下面web建站小编给大家简单介绍一下！
安装脚手架
npm install crypto
生成密钥
const crypto = require('crypto');
const key = crypto.randomBytes(24);
console.log(key.toString('hex'));
加密数据
const crypto = require('crypto');
const key = crypto.randomBytes(24);
const text = 'Hello, world!';
const cipher = crypto.createCipheriv('des-ede3', key, '');
let encrypted = cipher.update(text, 'utf8', 'hex');
encrypted += cipher.final('hex');
console.log(encrypted);
解密数据
const crypto = require('crypto');
const key = crypto.randomBytes(24);
const text = 'Hello, world!';
const cipher = crypto.createCipheriv('des-ede3', key, '');
let encrypted = cipher.update(text, 'utf8', 'hex');
encrypted += cipher.final('hex');
console.log(encrypted);
const decipher = crypto.createDecipheriv('des-ede3', key, '');
let decrypted = decipher.update(encrypted, 'hex', 'utf8');
decrypted += decipher.final('utf8');
console.log(decrypted);
