JavaScript字符串加密和解密？ [英] JavaScript string encryption and decryption?

问题描述

我有兴趣构建一个个人使用的小应用程序，使用JavaScript对客户端的信息进行加密和解密。加密的信息将被存储在服务器上的一个数据库中，但从未被解密的版本。

I'm interested in building a small app for personal use that will encrypt and decrypt information on the client side using JavaScript. The encrypted information will be stored in a database on a server, but never the decrypted version.

它不一定要超级安全，但是我想使用当前不间断的算法。

It doesn't have to be super duper secure, but I would like to use a currently unbroken algorithm.

理想情况下，我可以做一些像

Ideally I'd be able to do something like

var gibberish = encrypt(string, salt, key);

生成编码的字符串，像

var sensical = decrypt(gibberish, key);

稍后解码。

我已经看到这个：

我应该查看的任何其他库？

Any other libraries I should look at?

推荐答案

 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>
