小白求帮忙看 打开 licencia 文件的解密算法和过程

打开 licecia 调用和解密的代码
using System;

using
using System.Diagnostics;
using
using System.
using System.Security.Cryptography;
using System.Windows.Forms;
using Microsoft.VisualBasic;
using Microsoft.
using MySql.Data.MySqlClient;
namespace ORIENT
{
// Token: 0x0200001E RID: 30
[DesignerGenerated]
public partial class Config : Form
{
  // Token: 0x0600064B RID: 1611 RVA: 0x00036868 File Offset: 0x00034A68
  private void btnDesencriptar_Click(object sender, EventArgs e)
  {
   OpenFileDialog openFileDialog = new OpenFileDialog();
   openFileDialog.Filter = "Licencia File (*.orient)|*.orient";
   if (openFileDialog.ShowDialog() == DialogResult.OK)
   {
    string fileName = openFileDialog.FileName;
    StreamReader streamReader = new StreamReader(fileName);
    string text = streamReader.ReadToEnd();
    string text2 = text;
    int num = Strings.Len(text);
    text = Strings.Left(text, checked(num - 7));
    streamReader.Close();
    this.txtResultado.Text = this.Desencriptar(text);
    Module1.conn.Open();
    string s = "msviww$nqxt#tfuerhxwrw%+mi/hfwe.#zfoyjv$-*vjjmxwvt*0,";
    MySqlCommand mySqlCommand = new MySqlCommand(string.Concat(new string[]
    {
     Module1.d(s),
     text2,
     "') on duplicate key update data = '",
     text2,
     "'"
    }), Module1.conn);
    mySqlCommand.ExecuteNonQuery();
    Module1.conn.Close();
   }
  }
}
}


点击代码里的 Module1出来下面的代码

public static string NombreImpresora(int numero)
        {
            string result = "";
            MySqlCommand mySqlCommand = new MySqlCommand();
            mySqlCommand.Connection = Module1.conn2;
             = string.Concat(new string[]
            {
                "select alias from impresoracomanda where id = ",
                Conversions.ToString(numero),
                " and ordenador = '",
                ,
                "'"
            });
            try
            {
                Module1.conn2.Open();
                result = Conversions.ToString(mySqlCommand.ExecuteScalar());
                Module1.conn2.Close();
            }
            catch (Exception ex)
            {
            }
            return result;
        }


点击前面的Module1. 后面的 d 出来的代码

public static string d(string s)
        {
            int num = 1;
            int num2 = Strings.Len(s);
            checked
            {
                for (int i = num; i <= num2; i++)
                {
                    StringType.MidStmtStr(ref s, i, 1, Conversions.ToString(Strings.Chr(Strings.Asc(Strings.Mid(s, i, 1)) - i % 3 - 3)));
                }
                return s;
            }

求反向代码应该怎么写？就是编写一个licencia文件生成小程序代码

然后让打开的licecia 不要解密直接显示在方框里的代码应该怎么改？

还有把方框里的内容 调用加密后的 保存 按钮 代码应该怎么写？

希望大神们教一下，示范一下，谢谢！
