+
+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;
+
+    }
+}
+```
