js的怎么实现密码加密解密

const CryptoJS = require('crypto-js');

// 加密
function encrypt(text, secretKey) {
    const encrypted = CryptoJS.AES.encrypt(text, secretKey);
    return encrypted.toString();
}

// 解密
function decrypt(encryptedText, secretKey) {
    const decrypted = CryptoJS.AES.decrypt(encryptedText, secretKey);
    return decrypted.toString(CryptoJS.enc.Utf8);
}

// 使用示例
const secretKey = 'mySecretKey123';
const originalText = 'Hello, World!';
const encrypted = encrypt(originalText, secretKey);
console.log('Encrypted:', encrypted);

const decrypted = decrypt(encrypted, secretKey);
console.log('Decrypted:', decrypted);

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

// 生成密钥对
const key = new NodeRSA({ b: 512 }); // 512位密钥

// 加密
function encrypt(text) {
    return key.encrypt(text, 'base64');
}

// 解密
function decrypt(encryptedText) {
    return key.decrypt(encryptedText, 'utf8');
}

// 使用示例
const originalText = 'Hello, World!';
const encrypted = encrypt(originalText);
console.log('Encrypted:', encrypted);

const decrypted = decrypt(encrypted);
console.log('Decrypted:', decrypted);

const CryptoJS = require('crypto-js');

// 哈希
function hashPassword(password) {
    const hash = CryptoJS.SHA256(password);
    return hash.toString();
}

// 使用示例
const password = 'myPassword123';
const hashedPassword = hashPassword(password);
console.log('Hashed Password:', hashedPassword);
