I'm sorry, you shouldn't ever make your crackmes in .NET. All of the code can be decompiled.

Code: | Private Sub Number_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim v_str As String
Dim v_str1 As String
Dim v_str2 As String
v_str1 = Box2.[Text]
v_str2 = TrytoOpen.[Text]
If Microsoft.VisualBasic.Strings.Len(v_str1) < 20 Then
MyProject.Forms.Congratz.Visible = true
MyProject.Forms.Congratz.Label1.[Text] = "Uhh too short. . ."
Else
If Microsoft.VisualBasic.Strings.Len(v_str1) > 19 Then
For v_i As Integer = 1 To Microsoft.VisualBasic.Strings.Len(v_str1)
v_str = String.Concat(v_str, Conversions.ToString(Microsoft.VisualBasic.Strings.Chr(Microsoft.VisualBasic.Strings.Asc(Microsoft.VisualBasic.Strings.Mid(v_str1, v_i, 1)) + 7)))
Next v_i
If Operators.CompareString(v_str2, v_str, false) = 0 Then
MyProject.Forms.TryAgain.Visible = true
Panel1.Visible = true
Label1.Visible = true
Else
If (Operators.CompareString(v_str1, "Hello mate!", false) = 0) AndAlso (Operators.CompareString(v_str2, "How are you?", false) = 0) Then
MyProject.Forms.You_Win.Visible = true
Else
MyProject.Forms.Congratz.Visible = true
End If
End If
End If
End If
End Sub |
Suggestions:
Don't code in VB.NET for secure style applications.
Tool To Use
9Rays.Spices.Net Decompiler.
Password(s)
Looking at the code above, you can see it splits the string entered into line 1 letter by letter then adds 7 to the characters numeric value. It enforces 20 characters or longer and then you must match the 2nd box to the above box +7 on each letter.
A quick example:
1 = 8
So a quick password solution:
Box 1: 11111111111111111111
Box 2: 88888888888888888888

Cool . . . I think I found your decompiler that you used but I can't seem to get it to work. ..
