Decryption using DES Symmetric algorithm

I am trying to convert a .net decryption method to nodejs

public static string Decrypt(string strEnCryptedText)
    {
        string strDecryption;
        strDecryption = strEnCryptedText.Replace("~", "/");
        strDecryption = strDecryption.Replace("~", "\\");
        SymmetricAlgorithm mCSP = new DESCryptoServiceProvider();

        ICryptoTransform ct;
        System.IO.MemoryStream ms;
        CryptoStream cs;
        byte[] byt;
        byte[] key = { 0, 154, ...,...,... };
        byte[] IV = { 5, 10, ...,...,... };

        try
        {
            byt = Convert.FromBase64String(strDecryption);
            ct = mCSP.CreateDecryptor(key, IV);

            ms = new System.IO.MemoryStream();
            cs = new CryptoStream(ms, ct, CryptoStreamMode.Write);
            cs.Write(byt, 0, byt.Length);
            cs.FlushFinalBlock();
            cs.Close();

            return Encoding.UTF8.GetString(ms.ToArray());
        }
        catch
        {
            return "";
        }
    }

Any hints/suggestions would be helpful!
