Web端

封裝
封裝全域解密加密工具類檔案
下載CryptoJS并且從依賴包引入
import CryptoJS from ‘crypto-js/crypto-js’ //參考AES原始碼js
定義key值要與后端相同不同的話解密演算法會出問題
var key = CryptoJS.enc.Utf8.parse(“abcdef0123456789”);
加密函式
export function Encrypt(word) {
let srcs = CryptoJS.enc.Utf8.parse(word);
let encrypted = CryptoJS.AES.encrypt(srcs, key, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 });
return encrypted.ciphertext.toString().toUpperCase();
}
解密函式
export function Decrypt(word) {
let encryptedHexStr = CryptoJS.enc.Hex.parse(word);
let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);
let decrypt = CryptoJS.AES.decrypt(srcs, key, { mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 });
let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);
return decryptedStr.toString();
}
解密
在解密頁面import 引入解密函式
import {Decrypt} from “@/utils/aes/security.js”;

把后端出餐加密字符解密之后利用JSON.parse轉成json物件

加密
在引數發送頁面引入加密函式import {Encrypt} from “@/utils/aes/security.js”;

Query形式傳參需要以Encrypt轉換之后 以鍵值對的物件形式發送

Body形式只需將引數直接轉換后發送即可

  加密時引入#import “NSString+AES128.h”
  呼叫加密方法或解密方法，引數是密鑰
  NSString *enStr = [paramStr aes128_encrypt:XACAceEncrypt_KEY];
  NSString *deStr = [enStr aes128_decrypt:XACAceEncrypt_KEY];
