1、npm i crypto-js

2、crypto.js

 import CryptoJS from 'crypto-js'

const key = CryptoJS.enc.Utf8.parse("1234123412ABCDEF");

const iv = CryptoJS.enc.Utf8.parse('ABCDEF1234123412');

//解密方法

function Decrypt(word) {

    if(!word){

        return

    }

    let encryptedHexStr = CryptoJS.enc.Hex.parse(word);

    let srcs = CryptoJS.enc.Base64.stringify(encryptedHexStr);

    let decrypt = CryptoJS.AES.decrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });

    let decryptedStr = decrypt.toString(CryptoJS.enc.Utf8);

    return decryptedStr.toString();

}

//加密方法

function Encrypt(word) {

    if(!word){

        return

    }

    let srcs = CryptoJS.enc.Utf8.parse(word);

    let encrypted = CryptoJS.AES.encrypt(srcs, key, { iv: iv, mode: CryptoJS.mode.CBC, padding: CryptoJS.pad.Pkcs7 });

    return encrypted.ciphertext.toString().toUpperCase();

}

// ES6

export  {  

    Decrypt ,

    Encrypt

}

3、使用

import {Decrypt ，Encrypt } from './crypto.js'

Encrypt(str)

Decrypt (str)
