1.前端代码
// 1. vue package.json 引入crypto-js的依赖："crypto-js": "^4.0.0",
// 导入
import CryptoJS from 'crypto-js';
// 这两个必须是16位前后端一致
const key = CryptoJS.enc.Utf8.parse('FaceSunAweSome_K');
const iv = CryptoJS.enc.Utf8.parse('FaceSunAweSomeIV');
// 加密
const encrypt = (pass) => {
const password = CryptoJS.enc.Utf8.parse(pass);
return CryptoJS.AES.encrypt(password, key, {
mode: CryptoJS.mode.CBC,
iv: iv,
padding: CryptoJS.pad.Pkcs7
}).toString();
};
// 解密
const decrypt = (pass) => {
return CryptoJS.AES.decrypt(pass, key, {
mode: CryptoJS.mode.CBC,
iv: iv,
padding: CryptoJS.pad.Pkcs7
}).toString(CryptoJS.enc.Utf8);
};
export {
encrypt, decrypt
};
