how to use CryptoJS in javascript
提问by zhaowweny
I used CryptoJSinstead of nodejscrypto module because I just use the native JavaScript，but some codes can't work:
我使用CryptoJS而不是nodejscrypto 模块，因为我只是使用原生 JavaScript，但有些代码无法运行：
function aesEncrypt(text, secKey) {
const _text = text
const lv = new Buffer('0102030405060708', 'binary')
const _secKey = new Buffer(secKey, 'binary')
const cipher = crypto.createCipheriv('AES-128-CBC', _secKey, lv)
let encrypted = cipher.update(_text, 'utf8', 'base64')
encrypted += cipher.final('base64')
return encrypted
}
So how should I modify these codes?
那么我应该如何修改这些代码呢？

Here's a sample on how to use CryptoJs in webclient:
以下是有关如何在 webclient 中使用 CryptoJs 的示例：
// INIT
var myString = "blablabla Card game bla";
var myPassword = "myPassword";
// PROCESS
var encrypted = CryptoJS.AES.encrypt(myString, myPassword);
var decrypted = CryptoJS.AES.decrypt(encrypted, myPassword);
document.getElementById("demo0").innerHTML = myString;
document.getElementById("demo1").innerHTML = encrypted;
document.getElementById("demo2").innerHTML = decrypted;
document.getElementById("demo3").innerHTML = decrypted.toString(CryptoJS.enc.Utf8);<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/aes.js"></script>
</head>
<strong><label>Original String:</label></strong>
<span id="demo0"></span>
<br>
<br>
<strong><label>Encrypted:</label></strong>
<span id="demo1"></span>
<br>
<br>
<strong><label>Decrypted:</label></strong>
<span id="demo2"></span>
<br>
<br>
<strong><label>String after Decryption:</label></strong>
<span id="demo3"></span>
<br />
<br />
NB:
注意：
You might want to use CDN if you don't want to use node modules.
如果您不想使用节点模块，您可能想使用 CDN。

How about CryptoJS?
CryptoJS 怎么样？
It's a solid crypto library, with a lot of functionality. It implements hashers, HMAC, PBKDF2 and ciphers. In this case ciphers is what you need. Check out the quick-start quide on the project's homepage.
这是一个可靠的加密库，具有很多功能。它实现了哈希器、HMAC、PBKDF2 和密码。在这种情况下，密码就是您所需要的。查看项目主页上的快速入门指南。
var encrypted = CryptoJS.AES.encrypt("Message", "Secret Passphrase");
//U2FsdGVkX18ZUVvShFSES21qHsQEqZXMxQ9zgHy+bu0=
var decrypted = CryptoJS.AES.decrypt(encrypted, "Secret Passphrase");
//4d657373616765
document.getElementById("demo1").innerHTML = encrypted;
document.getElementById("demo2").innerHTML = decrypted;
document.getElementById("demo3").innerHTML = decrypted.toString(CryptoJS.enc.Utf8);Full working sample actually is:
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/aes.js"></script>
<br><br>
<label>encrypted</label>
<div id="demo1"></div>
<br>
<label>decrypted</label>
<div id="demo2"></div>
<br>
<label>Actual Message</label>
<div id="demo3"></div>
