【Java / JavaScript】AES加密解密

 

Java封装的AES加密解密工具类：

几个重要的参数信息

- 需要指定一个密钥串sKey 密钥内容自定义 数字 + 字母 + 特殊符号

- 加密方式为 AES

- AES下面的模式ECB

- ECB下面指定内嵌内容为PKCS5

public static void main(String[] args) throws Exception {   // 需要加密的字串   String cSrc = "999999";   System.out.println(cSrc);     // 加密   String enString = EncryptAESUtil.Encrypt(cSrc);   System.out.println("加密后的字串是：" + enString);     // 解密   String DeString = EncryptAESUtil.Decrypt(enString);   System.out.println("解密后的字串是：" + DeString); }

　　

JavaScript的AES加密解密工具类：

安装CryptoJS组件，先在NPM官网上找到CryptoJS的依赖地址：

?

1	https://www.npmjs.com/package/crypto-js

 

测试方法编写：

import Crypto from 'crypto-js'   test() {   const serverKey = 'cloud9.aesde.2023'   const key = Crypto.enc.Utf8.parse(serverKey)   const iv = Crypto.enc.Utf8.parse(serverKey)     // 生成密文   let encryptedData = Crypto.AES.encrypt('需要被加密的明文', key, {     iv: iv,     mode: Crypto.mode.ECB,     padding: Crypto.pad.Pkcs7   })   encryptedData = encryptedData.toString()   console.log(encryptedData)     const decryptedData = Crypto.AES.decrypt(encryptedData, key, {     iv: iv,     mode: Crypto.mode.ECB,     padding: Crypto.pad.Pkcs7   })     // 解密后的明文   console.log(decryptedData.toString(Crypto.enc.Utf8)) }

　　

 测试加密的密文和Java解密能一致之后，我们开始封装方法（aes-util.js）：

JS加密与Java解密：

 调用时引入需要的方法：

?

1 2 3 4

import { encryptByEcbPkcs7 } from '@/utils/encrypt/aes-util'   // 调用时方法 param.password = encryptByEcbPkcs7(param.password)

传入后台解码：

?

1	String DeString = EncryptAESUtil.Decrypt(enString);
