How to decrypt message with CryptoJS AES. I have a working Ruby example
提问by Priit
I'm able to decrypt AES encrypted message with Ruby like this:
我可以像这样用 Ruby 解密 AES 加密消息：
require 'openssl'
require 'base64'

Being new to CryptoJS I fail to put together working alternative. Here's what i've done so far:
作为 CryptoJS 的新手，我无法组合工作替代方案。这是我到目前为止所做的：

CryptoJS.AES.decrypt(atob(data).substring(16), key, {
iv: atob(cipher).substring(0, 16),

});
Does CryptoJS expect data, key and initialization vector in some different way? As far as i understand, the IV are the first 16 bytes in data.
CryptoJS 是否以某种不同的方式期望数据、密钥和初始化向量？据我了解，IV 是数据中的前 16 个字节。

This works for decryption using javascript.
这适用于使用 javascript 解密。
<script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.9-1/aes.js"></script>
var key = "2e35f242a46d67eeb74aabc37d5e5d05";
var data = CryptoJS.AES.encrypt("Message", key); // Encryption Part
var decrypted = CryptoJS.AES.decrypt(data, key).toString(CryptoJS.enc.Utf8); // Message
Guess I am a little late to the party.
猜猜我参加聚会有点晚了。

The important bits are to specify no salt in your input and pass the key as a WordArray as jlvaquero says. There are probably some efficiency improvements to be made, e.g. I'm guessing there's an easier way to convert a string to a WordArray than going to base64 and back, but at least it successfully decodes. I lifted the hex2a function from StackOverflow question Word Array to String.
重要的一点是在您的输入中不指定盐，并将密钥作为 jlvaquero 所说的 WordArray 传递。可能需要进行一些效率改进，例如，我猜有一种将字符串转换为 WordArray 的方法比转为 base64 并返回更简单，但至少它可以成功解码。我将 hex2a 函数从 StackOverflow 问题Word Array 提升到 String。
Edit: I figured out how to convert strings to WordArrays and vice-versa with CryptoJS so the extra base64 encode/decode and hex-to-ASCII function are not needed. Also it turns out the salt property need not be specified. This is more compact and efficient:
编辑：我想出了如何使用 CryptoJS 将字符串转换为 WordArrays，反之亦然，因此不需要额外的 base64 编码/解码和十六进制到 ASCII 函数。此外，事实证明不需要指定 salt 属性。这更紧凑和高效：

for the hex2a provided by another user, it may not working if ascii code is over 128 (i.e text contains chinese , etc)
对于其他用户提供的 hex2a，如果 ascii 代码超过 128（即文本包含中文等），它可能无法工作
you can use the follow to return proper unicode
您可以使用以下命令返回正确的 unicode
function hex2a(hex) {
var str = '';
for (var i = 0; i < hex.length; i += 2){
var dec = parseInt(hex.substr(i, 2), 16);
character = String.fromCharCode(dec);
if (dec > 127)
character = "%"+hex.substr(i,2);
str += character;
}
return decodeURI(str);
}
