js 加密分哪几种

const CryptoJS = require('crypto-js');
const secretKey = 'your-secret-key';

// 加密
const ciphertext = CryptoJS.AES.encrypt('Hello World', secretKey).toString();
console.log('Encrypted:', ciphertext);

// 解密
const bytes = CryptoJS.AES.decrypt(ciphertext, secretKey);
const originalText = bytes.toString(CryptoJS.enc.Utf8);
console.log('Decrypted:', originalText);

const NodeRSA = require('node-rsa');

// 生成密钥对
const key = new NodeRSA({ b: 512 });
const publicKey = key.exportKey('public');
const privateKey = key.exportKey('private');

// 加密
const encrypted = key.encrypt('Hello World', 'base64');
console.log('Encrypted:', encrypted);

// 解密
const decrypted = key.decrypt(encrypted, 'utf8');
console.log('Decrypted:', decrypted);

const crypto = require('crypto');

// 哈希
const hash = crypto.createHash('sha256');
hash.update('Hello World');
const hashed = hash.digest('hex');
console.log('Hashed:', hashed);
