C＃和Cryptojs的TripleDESCryptoServiceProvider给出不同的结果

Question

我真的需要你的帮助。我已经做了一个星期了。为什么使用c＃和javascript cryptojs在TripplesDes上进行加密时会得到不同的结果？请在下面查看我的代码。

c＃

public static string EncryptTxt()
{
    SHA512CryptoServiceProvider sha = new SHA512CryptoServiceProvider();

    using (var tdes = new TripleDESCryptoServiceProvider())
    {
        var msg = 'jvofs:JCV XXXXX:201911141547:12345678';
        var key = 'jjvofs';
        var keyOffset = 10;

        System.Text.UTF8Encoding UTF8 = new System.Text.UTF8Encoding();
        TripleDESCryptoServiceProvider TDESAlgorithm = new TripleDESCryptoServiceProvider();

        byte[] Results;
        byte[] newKeyx = new byte[24];

        byte[] keybyte = sha.ComputeHash(Encoding.UTF8.GetBytes(key));

        Array.Copy(keybyte, keyOffset, newKeyx, 0, newKeyx.Length);

        TDESAlgorithm.Key = newKeyx;
        TDESAlgorithm.Mode = CipherMode.ECB;
        TDESAlgorithm.Padding = PaddingMode.PKCS7;
        byte[] DataToEncrypt = UTF8.GetBytes(msg);
        try
        {
            ICryptoTransform Encryptor = TDESAlgorithm.CreateEncryptor();
            Results = Encryptor.TransformFinalBlock(DataToEncrypt, 0, DataToEncrypt.Length);
        }
        finally
        {
            TDESAlgorithm.Clear();
        }
        var a = Convert.ToBase64String(DataToEncrypt);
        var b = Convert.ToBase64String(newKeyx);
        var c = Convert.ToBase64String(Results);
        return Convert.ToBase64String(Results);
    }
}

[使用cryptojs的JavaScript

txtEncrypter = () => {
    const msg = 'jvofs:JCV XXXXX:201911141547:12345678';
    const key = 'jjvofs';
    const keyOffset = 10;
    const keybyte: any = this.wordArrayToByteArray(crypto.SHA512(key), 100);

    // For message
    const dataToEncrypt = crypto.enc.Utf8.parse(msg);
    const dte = this.wordArrayToByteArray(dataToEncrypt, 100);
    const dataToEncryptx = this._arrayBufferToBase64(dte);
    const dataToEncryptxx = crypto.enc.Utf8.parse(dataToEncryptx);

    // For key
    let newKeyx = keybyte.slice(keyOffset, 34);
    const newKeyxB4Splice = newKeyx;
    const newKeyxB4Splicex = this._arrayBufferToBase64(newKeyx);
    newKeyx = crypto.enc.Utf8.parse(newKeyx);

    const options = {
      mode: crypto.mode.ECB,
      padding: crypto.pad.Pkcs7
    };

    const encrypted = crypto.TripleDES.encrypt(dataToEncrypt, newKeyx, options);
    const base64String = encrypted.toString();
    console.log(base64String);
  }

解析消息和密钥的数据时，c＃和javascript都是相同的：

消息：

[[C＃] anZvZnM6SkNWIFhYWFhYOjIwMTkxMTE0MTU0NzoxMjM0NTY3OA ==

[cryptojs] anZvZnM6SkNWIFhYWFhYOjIwMTkxMTE0MTU0NzoxMjM0NTY3OA ==

键：

[C＃] smbkkmDrCBdRev7S4hLaWE16Nvym + 9gW

[cryptojs] smbkkmDrCBdRev7S4hLaWE16Nvym + 9gW

但是只要“ crypto.TripleDES.encrypt（....）”运行，我就会得到c＃和javascript的不同结果：

[[C＃] 1pjvBOB81iAOqsskZ + cM080yDU37XBoCwMhbYULwva / Nql5vbEMiPQ ==

[cryptojs] ncCcCYNy3jVsB / 95SaC2N1rH5Q + hX04WvScMvwmtkPkrnL7Ki1bmPg ==

请帮助我。非常感谢。
