ruoyi-vue框架密码加密传输

先看一下改造后的样子，输入的密码不会再以明文展示。

下面我主要把前后端改造的代码贴出来。

1.后端代码

RsaUtils类

在com.ruoyi.common.utils包下新建RsaUtils类，RsaUtils添加了@Component注解 generateKeyPair()构建密钥对添加了@Bean注解在项目启动时通过@Bean的方式将普通类事例化到spring容器中所以在系统启动后每次调用接口会是一样的公私秘钥每次重启后公私钥不同

import org.apache.commons.codec.binary.Base64;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.stereotype.Component;import javax.crypto.Cipher;
import java.security.*;
import java.security.interfaces.RSAPrivateKey;
import java.security.interfaces.RSAPublicKey;
import java.security.spec.PKCS8EncodedKeySpec;
import java.security.spec.X509EncodedKeySpec;@Component
public class RsaUtils {// Rsa 私钥 也可固定秘钥对 若依原写法(不安全)public static String privateKeys = "";private static String publicKeyStr = "";private static String privateKeyStr = "";private static final RsaKeyPair rsaKeyPair = new RsaKeyPair();private static final Logger logger = LoggerFactory.getLogger(RsaUtils.class);/*** 私钥解密** @param text 待解密的文本* @return 解密后的文本*/public static String decryptByPrivateKey(String text) throws Exception {
//        logger.info(rsaKeyPair.getPrivateKey());return decryptByPrivateKey(rsaKeyPair.getPrivateKey(), text);}/*** 公钥解密** @param publicKeyString 公钥* @param text            待解密的信息* @return 解密后的文本*/public static String decryptByPublicKey(String publicKeyString, String text) throws Exception {X509EncodedKeySpec x509EncodedKeySpec = new X509EncodedKeySpec(Base64.decodeBase64(publicKeyString));KeyFactory keyFactory = KeyFactory.getInstance("RSA");PublicKey publicKey = keyFactory.generatePublic(x509EncodedKeySpec);Cipher cipher = Cipher.getInstance("RSA");cipher.init(Cipher.DECRYPT_MODE, publicKey);byte[] result = cipher.doFinal(Base64.decodeBase64(text));return new String(result);}/*** 私钥加密** @param privateKeyString 私钥* @param text             待加密的信息* @return 加密后的文本*/public static String encryptByPrivateKey(String privateKeyString, String text) throws Exception {PKCS8EncodedKeySpec pkcs8EncodedKeySpec = new PKCS8EncodedKeySpec(Base64.decodeBase64(privateKeyString));KeyFactory keyFactory = KeyFactory.getInstance("RSA");PrivateKey privateKey = keyFactory.generatePrivate(pkcs8EncodedKeySpec);Cipher cipher = Cipher.getInstance("RSA");cipher.init(Cipher.ENCRYPT_MODE, privateKey);byte[] result = cipher.doFinal(text.getBytes());return Base64.encodeBase64String(result);}/*** 私钥解密** @param privateKeyString 私钥* @param text             待解密的文本* @return 解密后的文本*/public static String decryptByPrivateKey(String privateKeyString, String text) throws Exception {PKCS8EncodedKeySpec pkcs8EncodedKeySpec5 = new PKCS8EncodedKeySpec(Base64.decodeBase64(privateKeyString));KeyFactory keyFactory = KeyFactory.getInstance("RSA");PrivateKey privateKey = keyFactory.generatePrivate(pkcs8EncodedKeySpec5);Cipher cipher = Cipher.getInstance("RSA");cipher.init(Cipher.DECRYPT_MODE, privateKey);byte[] result = cipher.doFinal(Base64.decodeBase64(text));return new String(result);}/*** 公钥加密** @param publicKeyString 公钥* @param text            待加密的文本* @return 加密后的文本*/public static String encryptByPublicKey(String publicKeyString, String text) throws Exception {X509EncodedKeySpec x509EncodedKeySpec2 = new X509EncodedKeySpec(Base64.decodeBase64(publicKeyString));KeyFactory keyFactory = KeyFactory.getInstance("RSA");PublicKey publicKey = keyFactory.generatePublic(x509EncodedKeySpec2);Cipher cipher = Cipher.getInstance("RSA");cipher.init(Cipher.ENCRYPT_MODE, publicKey);byte[] result = cipher.doFinal(text.getBytes());return Base64.encodeBase64String(result);}/*** 构建RSA密钥对** @return 生成后的公私钥信息*/@Beanpublic void generateKeyPair() throws NoSuchAlgorithmException, NoSuchProviderException {KeyPairGenerator keyPairGenerator = KeyPairGenerator.getInstance("RSA");keyPairGenerator.initialize(1024);KeyPair keyPair = keyPairGenerator.generateKeyPair();RSAPublicKey rsaPublicKey = (RSAPublicKey) keyPair.getPublic();RSAPrivateKey rsaPrivateKey = (RSAPrivateKey) keyPair.getPrivate();String publicKeyString = Base64.encodeBase64String(rsaPublicKey.getEncoded());String privateKeyString = Base64.encodeBase64String(rsaPrivateKey.getEncoded());rsaKeyPair.setPrivateKey(privateKeyString);rsaKeyPair.setPublicKey(publicKeyString);publicKeyStr = publicKeyString;privateKeyStr = privateKeyString;}public static String getPublicKey() {return publicKeyStr;}public static String getPrivateKey() {return privateKeyStr;}public static RsaKeyPair rsaKeyPair() {return rsaKeyPair;}/*** RSA密钥对对象*/public static class RsaKeyPair {private String publicKey;private String privateKey;public void setPublicKey(String publicKey) {this.publicKey = publicKey;}public void setPrivateKey(String privateKey) {this.privateKey = privateKey;}public RsaKeyPair() {}public RsaKeyPair(String publicKey, String privateKey) {this.publicKey = publicKey;this.privateKey = privateKey;}public String getPublicKey() {return publicKey;}public String getPrivateKey() {return privateKey;}}
}

在SysLoginController添加获取公钥接口

/*** 获取公钥 前端用来密码加密** @return*/@GetMapping("/publicKey")public RsaUtils.RsaKeyPair publicKey() {return RsaUtils.rsaKeyPair();}

修改SysLoginService类中的login方法

/*** 登录验证** @param username 用户名* @param password 密码* @param code 验证码* @param uuid 唯一标识* @return 结果*/public String login(String username, String password, String code, String uuid){// 验证码校验validateCaptcha(username, code, uuid);// 登录前置校验loginPreCheck(username, password);// 用户验证Authentication authentication = null;try{//RsaUtils.decryptByPrivateKey(password)解密密码UsernamePasswordAuthenticationToken authenticationToken = new UsernamePasswordAuthenticationToken(username,  RsaUtils.decryptByPrivateKey(password));AuthenticationContextHolder.setContext(authenticationToken);// 该方法会去调用UserDetailsServiceImpl.loadUserByUsernameauthentication = authenticationManager.authenticate(authenticationToken);}catch (Exception e){if (e instanceof BadCredentialsException){AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, MessageUtils.message("user.password.not.match")));throw new UserPasswordNotMatchException();}else{AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_FAIL, e.getMessage()));throw new ServiceException(e.getMessage());}}finally{AuthenticationContextHolder.clearContext();}AsyncManager.me().execute(AsyncFactory.recordLogininfor(username, Constants.LOGIN_SUCCESS, MessageUtils.message("user.login.success")));LoginUser loginUser = (LoginUser) authentication.getPrincipal();recordLoginInfo(loginUser.getUserId());// 生成tokenreturn tokenService.createToken(loginUser);}

修改重置密码

/*** 重置密码*/@Log(title = "个人信息", businessType = BusinessType.UPDATE)@PutMapping("/updatePwd")public AjaxResult updatePwd(String oldPassword, String newPassword) throws Exception {LoginUser loginUser = tokenService.getLoginUser(ServletUtils.getRequest());String userName = loginUser.getUsername();//加密后的String password = loginUser.getPassword();//解密oldPassword = RsaUtils.decryptByPrivateKey(oldPassword);newPassword = RsaUtils.decryptByPrivateKey(newPassword);//拿原密码和加密后的解密if (!SecurityUtils.matchesPassword(oldPassword, password)) {return AjaxResult.error("修改密码失败，旧密码错误");}if (SecurityUtils.matchesPassword(newPassword, password)) {return AjaxResult.error("新密码不能与旧密码相同");}if (userService.resetUserPwd(userName, SecurityUtils.encryptPassword(newPassword)) > 0) {// 更新缓存用户密码loginUser.getUser().setPassword(SecurityUtils.encryptPassword(newPassword));tokenService.setLoginUser(loginUser);return AjaxResult.success();}return AjaxResult.error("修改密码异常，请联系管理员");}

在SecurityConfig中添加获取公钥接口

因为密码校验时会校验长度，加密后的密码会超出框架内原来设定的长度，修改UserConstants类中的PASSWORD_MAX_LENGTH

2.前端代码变动

jsencrypt.js

import JSEncrypt from 'jsencrypt/bin/jsencrypt.min'// 密钥对生成 http://web.chacuo.net/netrsakeypair//const publicKey = ''//const privateKey = ''// 加密
export function encrypt(txt, publicKey) {const encryptor = new JSEncrypt()encryptor.setPublicKey(publicKey) // 设置公钥return encryptor.encrypt(txt) // 对数据
}// 解密(暂无使用)
export function decrypt(txt) {const encryptor = new JSEncrypt()encryptor.setPrivateKey(privateKey) // 设置私钥return encryptor.decrypt(txt) // 对数据进行解密
}

login.js添加获取公钥路由

// 获取key
export function getPublicKey() {return request({url: '/publicKey',method: 'get',})
}

user.js修改登入方法，方便copy我直接全放进来了

import { login, logout, getInfo,getPublicKey } from '@/api/login'
import { getToken, setToken, removeToken } from '@/utils/auth'
import { encrypt, decrypt } from '@/utils/jsencrypt'const user = {state: {token: getToken(),id: '',name: '',avatar: '',roles: [],permissions: []},mutations: {SET_TOKEN: (state, token) => {state.token = token},SET_ID: (state, id) => {state.id = id},SET_NAME: (state, name) => {state.name = name},SET_AVATAR: (state, avatar) => {state.avatar = avatar},SET_ROLES: (state, roles) => {state.roles = roles},SET_PERMISSIONS: (state, permissions) => {state.permissions = permissions}},actions: {getPublicKey() {return new Promise((resolve, reject) => {getPublicKey().then(res => {resolve(res)}).catch(error => {reject(error)})})},// 登录Login({ commit, dispatch }, userInfo) {return new Promise((resolve, reject) => {dispatch('getPublicKey').then(res => {let publicKey = res.publicKeyconst username = userInfo.username.trim()//调用加密方法(传密码和公钥)const password = encrypt(userInfo.password, publicKey)const code = userInfo.codeconst uuid = userInfo.uuidlogin(username, password, code, uuid).then(res => {setToken(res.token)commit('SET_TOKEN', res.token)resolve()}).catch(error => {reject(error)})})})},// 获取用户信息GetInfo({ commit, state }) {return new Promise((resolve, reject) => {getInfo().then(res => {const user = res.userconst avatar = (user.avatar == "" || user.avatar == null) ? require("@/assets/images/profile.jpg") : process.env.VUE_APP_BASE_API + user.avatar;if (res.roles && res.roles.length > 0) { // 验证返回的roles是否是一个非空数组commit('SET_ROLES', res.roles)commit('SET_PERMISSIONS', res.permissions)} else {commit('SET_ROLES', ['ROLE_DEFAULT'])}commit('SET_ID', user.userId)commit('SET_NAME', user.userName)commit('SET_AVATAR', avatar)resolve(res)}).catch(error => {reject(error)})})},// 退出系统LogOut({ commit, state }) {return new Promise((resolve, reject) => {logout(state.token).then(() => {commit('SET_TOKEN', '')commit('SET_ROLES', [])commit('SET_PERMISSIONS', [])removeToken()resolve()}).catch(error => {reject(error)})})},// 前端 登出FedLogOut({ commit }) {return new Promise(resolve => {commit('SET_TOKEN', '')removeToken()resolve()})}}
}export default user

resetPwd.vue

methods: {getPublicKey() {return new Promise((resolve, reject) => {getPublicKey().then(res => {resolve(res)}).catch(error => {reject(error)})})},submit() {this.$refs["form"].validate(valid => {if (valid) {this.getPublicKey().then(res=>{let publicKey = res.publicKeyconsole.log("res.publicKey",res.publicKey)const oldPassword = encrypt(this.user.oldPassword, publicKey)const newPassword = encrypt(this.user.newPassword, publicKey)updateUserPwd(oldPassword, newPassword).then(response => {this.msgSuccess("修改成功");});})}});},close() {this.$store.dispatch("tagsView/delView", this.$route);this.$router.push({ path: "/index" });}}

这样就完成改造了。
