Vue AES 加密解密工具类

import CryptoJS from 'crypto-js';

const ALGORITHM = 'AES';
const TRANSFORMATION = 'AES/ECB/PKCS5Padding';

/**
 * 加密
 * @param {String} key 密钥
 * @param {String} plainText 明文
 * @return {String} 密文
 */
export function encrypt(key, plainText) {
    const secretKey = CryptoJS.enc.Utf8.parse(key);
    const encryptedBytes = CryptoJS.AES.encrypt(plainText, secretKey, {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7
    });
    return encryptedBytes.toString();
}

/**
 * 解密
 * @param {String} key 密钥
 * @param {String} cipherText 密文
 * @return {String} 明文
 */
export function decrypt(key, cipherText) {
    const secretKey = CryptoJS.enc.Utf8.parse(key);
    const decryptedBytes = CryptoJS.AES.decrypt(cipherText, secretKey, {
        mode: CryptoJS.mode.ECB,
        padding: CryptoJS.pad.Pkcs7
    });
    return decryptedBytes.toString(CryptoJS.enc.Utf8);
}

使用说明:

1. 确保您已在项目中安装了 crypto-js 库。
2. 将密钥 (key) 和明文 (plainText) 传递给 encrypt 函数进行加密。
3. 将密钥 (key) 和密文 (cipherText) 传递给 decrypt 函数进行解密。

示例:

import { encrypt, decrypt } from './aes'; // 导入工具函数

const key = 'your_secret_key'; // 密钥
const plainText = 'hello world'; // 明文

// 加密
const cipherText = encrypt(key, plainText);
console.log('密文:', cipherText);

// 解密
const decryptedText = decrypt(key, cipherText);
console.log('明文:', decryptedText);
