高考假期，想下载点资源看看，不了到都是特么m3u8的视频，部分还加了密，手动解密恢复过于麻烦，百度下，找到了这个软件
（话说大家都在拿什么软件下载m3u8呢?）
功能挺丰富，可惜要注册码，不然只给下载30s种的视频，这谁受得了呢？？？
正文开始
DIE瞧瞧，是个.NET写的程序，挺好
拖进DN SPY宰割
很轻松就找到了注册按钮处理函数
放大了给大家瞧瞧
private void button3_Click(object sender, EventArgs e)
{
Form1.UpdateAppConfig("sncode", this.textBox4.Text);
this.textBox3.Text = MachineCode.GetMachineCodeString();//获取机器码
bool flag = this.textBox4.Text.Equals(MachineCode.cksn(this.textBox3.Text));//计算注册码并与输入数据做对比
if (flag)
{
this.snflg = true;
MessageBox.Show("注册成功，不限制文件数。");
this.groupBox3.Text = "已注册版本";
}
else
{
this.snflg = false;
MessageBox.Show("注册失败，请联系作者。");
this.groupBox3.Text = "未注册版本（仅可处理10个文件）";
}
}
再来瞧瞧 MachineCode类里有什么好玩的东东

if (flag)

}
catch (Exception)

}
return text.ToString();
}

private static MachineCode machineCode;
}
}
这么多就是为了算出机器码，这效率。。。。。
废话不多说，反编译码复制进vs ide，建个C#项目（我用的是VS2010）

OK-编译-链接-运行-一次通过，看看效果怎么样
完美通过：本文终------------》下片去喽
