Vue与Java使用AES加密与解密

CBC模式（通过偏移值进行加密，更具安全性）

一、VUE：

1、安装

npm install crypto-js

 2、编写公用js（在common文件夹下创建一个crypto.js）

注意：key最少要有16个字符，iv最少6个字符，否则解密返回结果为空。

import CryptoJS from 'crypto-js'const KEY = CryptoJS.enc.Utf8.parse('0123456789123456')
const IV = CryptoJS.enc.Utf8.parse('0123456789123456')// 加密函数
export function encryptData(data) {const encrypted = CryptoJS.AES.encrypt(data,KEY,{iv: IV,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.Pkcs7})return encrypted.toString()
}// 解密函数
export function decryptData(data) {const decrypted = CryptoJS.AES.decrypt(data,KEY,{iv: IV,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.Pkcs7})return CryptoJS.enc.Utf8.stringify(decrypted)
}export default {encryptData,decryptData
}

3、引入js使用

<script>
// 引入js
import { encryptData, decryptData } from '@/common/crypto.js'
export default {data() {return {},},created() {// 调用方法const password = encryptData('123456777')console.log(password, "加密");console.log(decryptData(password),'解密')},methods: {},
};
</script>

二、Java：

1、导入

<dependency><groupId>org.bouncycastle</groupId><artifactId>bcprov-jdk15on</artifactId><version>1.60</version>
</dependency>

2、新建工具类

package com.nview.utils.aes;import org.apache.commons.codec.binary.Base64;import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;/*** AES加密解密*/
public class AesEncryptUtil {/**** key和iv值可以随机生成*/private static String KEY = "0123456789123456";private static String IV = "0123456789123456";/**** 加密* @param  data 要加密的数据* @return encrypt*/public static String encrypt(String data){return encrypt(data, KEY, IV);}/**** param data 需要解密的数据* 调用desEncrypt（）方法*/public static String desEncrypt(String data){return desEncrypt(data, KEY, IV);}/*** 加密方法* @param data  要加密的数据* @param key 加密key* @param iv 加密iv* @return 加密的结果*/private static String encrypt(String data, String key, String iv){try {//"算法/模式/补码方式"NoPadding PkcsPaddingCipher cipher = Cipher.getInstance("AES/CBC/NoPadding");int blockSize = cipher.getBlockSize();byte[] dataBytes = data.getBytes();int plaintextLength = dataBytes.length;if (plaintextLength % blockSize != 0) {plaintextLength = plaintextLength + (blockSize - (plaintextLength % blockSize));}byte[] plaintext = new byte[plaintextLength];System.arraycopy(dataBytes, 0, plaintext, 0, dataBytes.length);SecretKeySpec keyspec = new SecretKeySpec(key.getBytes(), "AES");IvParameterSpec ivspec = new IvParameterSpec(iv.getBytes());cipher.init(Cipher.ENCRYPT_MODE, keyspec, ivspec);byte[] encrypted = cipher.doFinal(plaintext);return new Base64().encodeToString(encrypted);} catch (Exception e) {e.printStackTrace();return null;}}/*** 解密方法* @param data 要解密的数据* @param key  解密key* @param iv 解密iv* @return 解密的结果*/private static String desEncrypt(String data, String key, String iv){try {byte[] encrypted1 = new Base64().decode(data);Cipher cipher = Cipher.getInstance("AES/CBC/NoPadding");SecretKeySpec keySpec = new SecretKeySpec(key.getBytes(), "AES");IvParameterSpec ivSpec = new IvParameterSpec(iv.getBytes());cipher.init(Cipher.DECRYPT_MODE, keySpec, ivSpec);byte[] original = cipher.doFinal(encrypted1);return new String(original).trim();} catch (Exception e) {e.printStackTrace();return null;}}
}
