前端
- 安装crypto-js
javascript
npm install crypto-js
- 加密
javascript
//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
javascript
const password = encrypt(userInfo.password);

* Description: 配合前端CryptoJS实现加密、解密工作。
* CryptoJS 是一个 JavaScript 库,提供了一系列密码学函数和工具,用于加密、解密、生成摘要等任务。
* 它支持多种加密算法,包括常见的对称加密算法(如 AES、DES)和非对称加密算法(如 RSA)。
