重点提要：crypto-js 应对key进行 md5 散列
AES加密 规定了密钥长度，crypto通过md5的方式使key设为了定长，所以crypto-js（包括java）为了与crypto结果保持一致，应当对key进行md5散列，且散列结果不为字符串，而是数组（即WordArry，类比Java中的byte[]，Node.js中的Buffer），以下附上crypto-js、crypto、java三端AES-ECB-128加解密代码：
1、crypto-js（web前端、小程序）
import CryptoJS from 'crypto-js'; // 先全局安装：npm install crypto-js --save-dev//aes ecb 128 加密
export const aesEncrypt = (content: string, secret: string) => {const srcs = CryptoJS.enc.Utf8.parse(content);const encrypted = CryptoJS.AES.encrypt(srcs, CryptoJS.MD5(secret), {iv: [],mode: CryptoJS.mode.ECB,padding: CryptoJS.pad.Pkcs7});return encrypted.toString();
}//aes ecb 128 解密
export const aesDecrypt = (content: string, secret: string) => {//content为密文，无需做处理即可const decrypt = CryptoJS.AES.decrypt(content, CryptoJS.MD5(secret) , {iv: [],mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7});const decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);return decryptedStr.toString();
}
2：node crypto
const crypto = require('crypto');const AES_ALGORITHM = "aes-ebc-128";
const UTF8 = "utf-8";
const BASE64 = "base64";//aes ecb 128 加密
export const aseEncrypt = (content: string, secret: string) => {const cipherChunks = [];const cipher = crypto.createCipher(AES_ALGORITHM, secret);cipherChunks.push(cipher.update(content, UTF8, BASE64));cipherChunks.push(cipher.final(BASE64));return cipherChunks.join('');
}//aes ecb 128 解密
export const aseDecrypt = (content: string, secret: string) => {const decipherChunks = [];const decipher = crypto.createDecipher(AES_ALGORITHM, secret);decipherChunks.push(decipher.update(content, BASE64, UTF8));decipherChunks.push(decipher.final(UTF8));return decipherChunks.join('');
}
3：Java(Android)
