I believe this may be completely new to some of you, so here is a quick description:
|
||||
|
||||
In this protect-me, you are to take the keygen and make a serial check for it.
|
||||
Example -
|
||||
|
||||
With this protectme, you are to look at the keygen, and make a program that tells you if the serial is correct or incorrect, just like most programs that ask you to enter a serial.
|
||||
|
||||
If you do not understand, wait untill someone makes a solution for this, then run the program.
|
||||
|
||||
L8rz folks!

反向crackme?
|
||||
|
||||
一看是vb.net 内心狂喜
|
||||
|
||||
先来看一下serial是怎么生成的:
|
||||
|
||||
```c#
|
||||
// TextBox1:Name, TextBox2:Serial
|
||||
private void Button1_Click(object sender, EventArgs e)
|
||||
{
|
||||
if (this.TextBox1.Text.Length <= 7)
|
||||
{
|
||||
Interaction.MsgBox("Name must be at least 8 chars!!!", MsgBoxStyle.OkOnly, null);
|
||||
}
|
||||
else
|
||||
{
|
||||
this.lengthofbox = StringType.FromInteger(this.TextBox1.Text.Length);
|
||||
this.TextBox2.Text = this.lengthofbox + this.TextBox1.Text.Remove(3, 5);
|
||||
this.TextBox3.Text = this.TextBox2.Text;
|
||||
this.string2 = StringType.FromDouble(DoubleType.FromString(this.lengthofbox) / (double)this.TextBox3.Text.Length);
|
||||
this.TextBox2.Text = this.string2 + this.TextBox3.Text;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
这样一来就能写出以下检查代码
|
||||
|
||||
```c#
|
||||
static bool ValidateNameSerial(string name, string serial, ref string ErrReason)
|
||||
{
|
||||
int length = name.Length;
|
||||
if (length <= 7)
|
||||
{
|
||||
ErrReason = "Name length must be greater than 7";
|
||||
return false;
|
||||
}
|
||||
else
|
||||
{
|
||||
string temp2 = length + name.Remove(3, 5);
|
||||
if ((length / (double)temp2.Length) + temp2 == serial)
|
||||
return true;
|
||||
ErrReason = "Wrong Serial";
|
||||
return false;
|
||||
|
||||
}
|
||||
}
|
||||
```
