uniapp 小程序 aes前后端加密解密交互

 

 

后端的：springboot 自定义注解使用AOP实现请求参数解密以及响应数据加密

小程序端

1. 首先引入aes.js

module.exports = CryptoJS

2. 加密解密方法

var CryptoJS = require('./aes.js'); //引用AES源码js
var key = CryptoJS.enc.Utf8.parse("0102030405060708"); //十六位十六进制数作为秘钥
var iv = CryptoJS.enc.Utf8.parse('0102030405060708');//十六位十六进制数作为秘钥偏移量
//解密方法
function Decrypt(word) {
    var encryptedHexStr = CryptoJS.enc.Hex.parse(word);
    var srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
    var decrypt = CryptoJS.AES.decrypt(srcs, key, {
        iv: iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    var decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
    return decryptedStr.toString();
}
//加密方法
function Encrypt(word) {
    var srcs = CryptoJS.enc.Utf8.parse(word);
    var encrypted = CryptoJS.AES.encrypt(srcs, key, {
        iv: iv,
        mode: CryptoJS.mode.CBC,
        padding: CryptoJS.pad.Pkcs7
    });
    return encrypted.ciphertext.toString().toUpperCase();
}

//暴露接口
module.exports.Decrypt = Decrypt;
module.exports.Encrypt = Encrypt;

3. 在小程序js中可以调用

const CryptoJS = require('../../utils/aes/public.js')
// 加密
console.log(CryptoJS.Encrypt('123456'))
// 5A09AE89579945B7AB80A9DC08F66FAA
// 解密
console.log(CryptoJS.Decrypt('5A09AE89579945B7AB80A9DC08F66FAA'))
// 123456
