C#加密NodeJS解密

C#代码：

    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("encrypted as: {0}", TripleDESEncrypt("12345", "abcdefghijklmnop", "pgfYadhCout=", false));

        }
        public static string TripleDESEncrypt(string toEncrypt, string key, string iv, bool useHashing)
        {
            byte[] keyArray;
            byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(toEncrypt);
            byte[] ivArray = Convert.FromBase64String(iv);

            if (useHashing)
            {
                MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
                keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(key));
            }
            else
                keyArray = UTF8Encoding.UTF8.GetBytes(key);

            var tdes = new TripleDESCryptoServiceProvider();
            tdes.Key = keyArray;
            tdes.IV = ivArray;
            // tdes.Mode = CipherMode.CBC;  // which is default     
            // tdes.Padding = PaddingMode.PKCS7;  // which is default

            ICryptoTransform cTransform = tdes.CreateEncryptor();
            byte[] resultArray = cTransform.TransformFinalBlock(toEncryptArray, 0,
                toEncryptArray.Length);
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
        }
    }

NodeJS的javascript代码：

var crypto = require('crypto');
var alg = 'des-ede-cbc';
var key = new Buffer('abcdefghijklmnop', 'utf-8');
var iv = new Buffer('pgfYadhCout=', 'base64');

var EncryptDES = function (data) {
  var cipher = crypto.createCipheriv(alg, key, iv);
  var encoded = cipher.update(data, 'ascii', 'base64');
  encoded += cipher.final('base64');
  return encoded;
};

var DecryptDES = function (data) {   
  var encrypted = new Buffer(data, 'base64');                
  var decipher = crypto.createDecipheriv(alg, key, iv);
  var decoded = decipher.update(encrypted, 'binary', 'ascii');
  decoded += decipher.final('ascii');
  return decoded;
};
