vue登陆密码加密，java后端解密

news 2025/7/4 13:19:13

前端

安装crypto-js

npm install crypto-js

加密

//引入crypto-js
import CryptoJS from 'crypto-js';/** ---密码加密 start--- */
const SECRET_KEY = CryptoJS.enc.Utf8.parse("a15q8f6s5s1a2v3s");
const SECRET_IV = CryptoJS.enc.Utf8.parse("a3c6g5h4v9sss3v5");function encrypt(pwd) {let srcs = CryptoJS.enc.Utf8.parse(pwd);let encrypted = CryptoJS.AES.encrypt(srcs, SECRET_KEY, {iv: SECRET_IV ,mode: CryptoJS.mode.CBC,padding: CryptoJS.pad.ZeroPadding})return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
}
/** ---密码加密end--- */

登陆之前调用encrypt给pwd加密

const password = encrypt(userInfo.password);

后端

解密工具类CryptoUtil
