前端des加密信息

​​idnumberDes.js​​ 加解密封装
需要先安装 ​​CryptoJS​​ npm i crypto-js
import CryptoJS from "crypto-js";

// des加密,isHex表示结果是否有密文,输出hex,否则输出base64
// key为加密的秘钥。message 为需要加密的信息
let encryptByDES = function (message, key, isHex = true) {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
    var encrypted = CryptoJS.DES.encrypt(message, keyHex, {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7
    });
    if (isHex) return encrypted.ciphertext.toString();
    else return encrypted.toString();
}

// DES 解密,isHex表示对hex解密,否则对base64解密
let decryptByDES = (ciphertext, key, isHex = true) => {
    var keyHex = CryptoJS.enc.Utf8.parse(key);
    if (isHex) ciphertext = CryptoJS.enc.Hex.parse(ciphertext)
    else ciphertext = CryptoJS.enc.Base64.parse(ciphertext)
    var decrypted = CryptoJS.DES.decrypt({ ciphertext }, keyHex, {
      mode: CryptoJS.mode.ECB,
      padding: CryptoJS.pad.Pkcs7
    });
    return decrypted.toString(CryptoJS.enc.Utf8);
}

export {
    encryptByDES, decryptByDES
}

用法:
import { encryptByDES } from '../../../utils/idnumberDes';


// message 加密信息key加密秘钥key与后端定义一致
let num = encryptByDES(message,key)
console.log(num)
