三重DES ECB加密红宝石

Question

我在.NET C＃中有一个示例代码，需要将其转换为RUBY。

 public static string Encrypt(string pstrText)
        {
            byte[] keyArray;
            byte[] toEncryptArray = UTF8Encoding.UTF8.GetBytes(pstrText);
                MD5CryptoServiceProvider hashmd5 = new MD5CryptoServiceProvider();
                keyArray = hashmd5.ComputeHash(UTF8Encoding.UTF8.GetBytes(secKey));
                hashmd5.Clear();
            TripleDESCryptoServiceProvider tdes = new TripleDESCryptoServiceProvider();
            tdes.Key = keyArray;
            tdes.Mode = CipherMode.ECB;
            tdes.Padding = PaddingMode.PKCS7;
            ICryptoTransform cTransform = tdes.CreateEncryptor();
            byte[] resultArray =cTransform.TransformFinalBlock(toEncryptArray, 0, toEncryptArray.Length);
            tdes.Clear();
            return Convert.ToBase64String(resultArray, 0, resultArray.Length);
        }

我已经尝试过使用OPENSSL：CIPHER，到目前为止-

def encrypt data
secret = "******************"
md5 = Digest::MD5.hexdigest(secret)
des = OpenSSL::Cipher::Cipher.new 'DES-EDE3'
des.encrypt
des.key = md5
update_value = des.update(data)
up_final = update_value + des.final
puts Base64.encode64(up_final).gsub(/\n/, "")
end

C＃和RUBY中的结果不匹配。我要去哪里错了？
