vue前端密码加密，springboot后端密码解密

1.模块安装

1	npm install crypto-js

2.src–>util–>secret.js

import CryptoJS from 'crypto-js'

// 默认的 KEY 与 iv 如果没有给
const KEY = CryptoJS.enc.Utf8.parse("1234567890123456");
const IV = CryptoJS.enc.Utf8.parse('1234567890123456');
/**
* AES加密：字符串 key iv 返回base64
*/
export function Encrypt(word, keyStr, ivStr) {
let key = KEY;
let iv = IV;
if (keyStr) {
key = CryptoJS.enc.Utf8.parse(keyStr);
iv = CryptoJS.enc.Utf8.parse(ivStr);
}
let srcs = CryptoJS.enc.Utf8.parse(word);
var encrypted = CryptoJS.AES.encrypt(srcs, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.ZeroPadding
});
return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);

}
/**
* AES 解密：字符串 key iv 返回base64
*
* @return {string}
*/
export function Decrypt(word, keyStr, ivStr) {
let key = KEY;
let iv = IV;

if (keyStr) {
key = CryptoJS.enc.Utf8.parse(keyStr);
iv = CryptoJS.enc.Utf8.parse(ivStr);
}

let base64 = CryptoJS.enc.Base64.parse(word);
let src = CryptoJS.enc.Base64.stringify(base64);

let decrypt = CryptoJS.AES.decrypt(src, key, {
iv: iv,
mode: CryptoJS.mode.CBC,
padding: CryptoJS.pad.ZeroPadding
});

let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
return decryptedStr.toString();
}

3.login.vue引入加密方法

1	import {Encrypt} from '../utils/Secret.js'

4.login.vue登录请求发起，对密码参数加密

let param={
username:this.loginForm.username,
password:Encrypt(this.loginForm.password) //密码加密
}

5.后端pom.xml
