TripleDES .Net to TripleDES (密码-js) Javascript

Question

我花了一段时间研究所有的解决方案，但似乎还是有些不对劲。我在.Net中看到的加密字符串与我在Cryto中看到的输出不匹配。有什么不对的？

    public static void Encrypt()
    {
        string toEncrypt = "123456";
        string key = "hello";

        TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
        MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
        byte[] keyArray = hashmd5.ComputeHash(UnicodeEncoding.Unicode.GetBytes(key));
        tdes.Key = keyArray;
        tdes.Mode = CipherMode.ECB;

        ICryptoTransform cTransform = tdes.CreateEncryptor();
        byte[] toEncryptArray = UnicodeEncoding.Unicode.GetBytes(toEncrypt);
        byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
        string finalString = Convert.ToBase64String(resultArray);

        Console.WriteLine("Output encrypted .Net: " + finalString);
    }

而使用crypto的等价Javascript是

    Encrypt = () => {
        var CryptoJS = require('crypto-js');
        var text = '123456'
        var key = "hello";

        key = CryptoJS.enc.Utf16LE.parse(key);
        key = CryptoJS.MD5(key)

        var options = {
           mode: CryptoJS.mode.ECB, 
        };

        var textWordArray = CryptoJS.enc.Utf16LE.parse(text); 
        var encrypted = CryptoJS.TripleDES.encrypt(textWordArray, key, options);   
        var base64String = encrypted.toString();    
        console.log('Output JS Encrypted: ' + base64String);   
     }  

我得到了yGOnLhoVpIHQOCbAn51FTA==的.Net和d5Lg8k8cz68T6akDI0KQrA==的密码-js。

我已经解决了这个问题。tripledes.js (CryptoJS包)内部的控制台日志显示，在MD5 Hash之后，我又丢失了64位。

this._des1 = DES.createEncryptor(WordArray.create(keyWords.slice(0, 2)));
this._des2 = DES.createEncryptor(WordArray.create(keyWords.slice(2, 4)));
this._des3 = DES.createEncryptor(WordArray.create(keyWords.slice(4, 6)));

key.words长度为4，而非6。因此，des3有一种空的假丝。解决方法是将索引0和1的值推入关键字数组。当长度现在为6时，des3得到des1的值。即keyWords.slice(0，2) = keyWords.slice(4，6)。

Encrypt = () => {
    var CryptoJS = require('crypto-js');
    var text = '123456'
    var key = "hello";

    key = CryptoJS.enc.Utf16LE.parse(key);
    key = CryptoJS.MD5(key)
    key.words.push(key.words[0], key.words[1]) // FIX FIX FIX

    var options = {
       mode: CryptoJS.mode.ECB, 
    };

    var textWordArray = CryptoJS.enc.Utf16LE.parse(text); 
    var encrypted = CryptoJS.TripleDES.encrypt(textWordArray, key, options);   
    var base64String = encrypted.toString();    
    console.log('Output JS Encrypted: ' + base64String);   
 }
