测试开源.net 混淆器ConfuserEx

由于公司业务需要简单的把代码加密混淆，于是了解了一下相关的工具然后打算用ConfuserEx试试。

开始工作

1.简单编写一个产生随机数的Winform窗口程序

代码如下

using System;
using System.Windows.Forms;

namespace ConfuserEx_Test
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
var max = (double)numericUpDown1.Value;
var min = (double)numericUpDown2.Value;
Random random = new Random();
double v = random.NextDouble() * (max -min) + min;
label1.Text = v.ToString();
textBox1.AppendText(v.ToString() + "\r\n");

}
}
}

Form1.cs

using System;
using System.Windows.Forms;

namespace ConfuserEx_Test
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            var max = (double)numericUpDown1.Value;
            var min = (double)numericUpDown2.Value;
            Random random = new Random();
            double v = random.NextDouble() * (max -min) + min;
            label1.Text = v.ToString();
            textBox1.AppendText(v.ToString() + "\r\n");

        }
    }
}

namespace ConfuserEx_Test
{
partial class Form1
{
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.IContainer components = null;

/// <summary>

protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

其功能如图：

2.下载打开ConfuserEx使用

2.1 将生成的exe文件拖拽到ConfuserEx的Project中

2.2在Settings中选中Packer(据说dll文件不是这样的)，再点击exe文件，添加一个True。

2.3点击Protect!看到Finished at xx:xx, xx:xx elapsed.表示完成

3.测试加密混淆结果

3.1下载ILSpy--(百度百科:ILspy是一个开源的.net反编译软件，使用十分方便。)

3.2将保护前编译出的exe文件拖拉到ILSpy中

很方便就能够看到源码

3.2 将保护后的exe文件拖拉到ILSpy中与之前的做对比

4.结论

简单的测试了一下，这种保护便于操作，有明显的保护效果，能够防止只会下载反编译软件来获得源码的人，但是可能不是所有反编译软件都能防止。只是做个简单保护。

后面我会做一个Reflector反编译实验以及脱壳后再来反编译。

附加1

Reflector反编译实验结果，保护后的直接打不开
