vue前端密碼加密+ springboot后端密碼解密

1.模塊安裝

npm install crypto-js

2.新建插件secret.js

import CryptoJS from 'crypto-js'

// 默認的 KEY 與 iv 如果沒有給
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

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

4.login.vue登錄請求發起，對密碼參數加密

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

5.后端pom.xml

<!--密碼解密-->
 <dependency>
     <groupId>org.bouncycastle</groupId>
     <artifactId>bcprov-jdk15on</artifactId>
     <version>1.60</version>
</dependency>

6.后端utils–>secretUtil.java

package com.xiaobing.demo01.utils;

import org.apache.tomcat.util.codec.binary.Base64;

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class PasswordUtil {
    /***
     * key和iv值可以隨機生成
     */
    private static String KEY = "1234567890123456";

    private static String IV = "1234567890123456";

    /***
     * 加密
     * @param  data 要加密的數據
     * @return encrypt
     */
    public static String encrypt(String data){
        return encrypt(data, KEY, IV);
    }

    /***
     * param data 需要解密的數據
     * 調用desEncrypt（）方法
     */
    public static String desEncrypt(String data){
        return desEncrypt(data, KEY, IV);
    }

    /**
     * 加密方法
     * @param data  要加密的數據
     * @param key 加密key
     * @param iv 加密iv
     * @return 加密的結果

     */
    private static String encrypt(String data, String key, String iv){
        try {
            //"算法/模式/補碼方式"NoPadding PkcsPadding
            Cipher 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 要解密的數據
     * @param key  解密key
     * @param iv 解密iv
     * @return 解密的結果
     */
    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;
        }
    }

}

7.登錄Controller對前端傳來的密碼解密(先導入加密工具類)

//    PasswordUtil.desEncrypt：  前端傳來的加密密碼進行解密
       User user=userService.loginByInfo(username, 
       PasswordUtil.desEncrypt(password));

8.親測后備份吧。感謝大佬原文：https://blog.csdn.net/weixin_43934513/article/details/108982981
