encryption - JavaScript字符串加密和解密？(JavaScript string encryption and decryption?)

Question

I'm interested in building a small app for personal use that will encrypt and decrypt information on the client side using JavaScript.

(我对构建一个供个人使用的小型应用程序感兴趣，该应用程序将使用JavaScript在客户端加密和解密信息。)

The encrypted information will be stored in a database on a server, but never the decrypted version.

(加密的信息将存储在服务器上的数据库中，但不会存储在解密版本中。)

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

(它不必是超级duper安全的，但是我想使用当前不间断的算法。)

Ideally I'd be able to do something like

(理想情况下，我可以做类似的事情)

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

to generate the encoded string, and something like

(生成编码的字符串，诸如此类)

var sensical = decrypt(gibberish, key);

to decode it later.

(稍后再解码。)

So far I've seen this: http://bitwiseshiftleft.github.io/sjcl/

(到目前为止，我已经看到了： http : //bitwiseshiftleft.github.io/sjcl/)

Any other libraries I should look at?

(我应该看看其他图书馆吗？)

  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);
