使用CryptoJS在JavaScript中加密并在C＃中解密

Question

我想使用CryptoJS在JavaScript中加密并在C＃中解密。花了相当多的时间试图让这两种技术返回相同的输出。不过，输出是不同的 - CryptoJS生成的加密字符串与C＃生成的加密字符串不同。我究竟做错了什么？感谢您的帮助。

我不得不做类似的事情最近，这里是一个什么你拍摄的一个工作版本 - 这种加密在C＃服务器与System.Security.Cryptography的AES提供一个字符串，然后发送加密文本到客户端，用CryptoJS库在JavaScript中解密：

<%@ Page Language="C#" %> 
<%@ Import Namespace="System.Security.Cryptography" %> 
<%@ Import Namespace="System.IO" %> 

<script src="http://crypto-js.googlecode.com/svn/tags/3.1.2/build/rollups/aes.js"></script> 
<script> 
    window.onload = function (e) { 
     var key = CryptoJS.enc.Base64.parse(document.getElementById('key').innerText); 
     var iv = CryptoJS.enc.Base64.parse(document.getElementById('iv').innerText); 
     var ciphertext = document.getElementById('ciphertext').innerText; 
     var decrypted = CryptoJS.AES.decrypt(ciphertext, key, { iv: iv }); 

     document.getElementById('output').innerText = decrypted.toString(CryptoJS.enc.Utf8); 
    } 
</script> 

<% 
    string plaintext = "the quick brown fox jumped over the lazy dog"; 
    string ciphertext; 
    string decryptedtext; 

    UTF8Encoding utf8 = new UTF8Encoding(); 

    AesCryptoServiceProvider aes = new AesCryptoServiceProvider(); 

    using (ICryptoTransform encryptor = aes.CreateEncryptor(aes.Key, aes.IV)) { 
     MemoryStream ms = new MemoryStream(); 
     CryptoStream cs = new CryptoStream(ms, encryptor, CryptoStreamMode.Write); 
     byte[] bytes = utf8.GetBytes(plaintext); 
     cs.Write(bytes, 0, bytes.Length); 
     cs.FlushFinalBlock(); 
     ms.Position = 0; 
     bytes = new byte[ms.Length]; 
     ms.Read(bytes, 0, bytes.Length); 
     ciphertext = Convert.ToBase64String(bytes); 
    } 

    using (ICryptoTransform decryptor = aes.CreateDecryptor(aes.Key, aes.IV)) 
    { 
     MemoryStream ms = new MemoryStream(); 
     CryptoStream cs = new CryptoStream(ms, decryptor, CryptoStreamMode.Write); 
     byte[] bytes = Convert.FromBase64String(ciphertext); 
     cs.Write(bytes, 0, bytes.Length); 
     cs.FlushFinalBlock(); 
     ms.Position = 0; 
     bytes = new byte[ms.Length]; 
     ms.Read(bytes, 0, bytes.Length); 
     decryptedtext = utf8.GetString(bytes); 
    }  
%>
