PostPosted: Fri Jul 13, 2007 10:10 am    Post subject: Crackme Question. Reply with quote

I'll be making my first Crackme. I've already started, but I can't compile it until I get my new computer.
Anyways, I'm just asking for someone that I can ask some questions to/ask for some tips. I'm not a good programmer- take that into consideration before you say anything though.
I already think that I have a good idea for a easy-medium crackme, and I've already put in some sort of feature that makes the crackme look easier than it is.

So anyone willing to help?

(By the way, posted here since it's not an actual Crackme release.)

i think my first crackme will be a edit box and a button

use an algorithm to encrypt a string and require that to pass?

a crackme is bassed on how good the programmer is and which tips/tricks you can do.

If edit1.text = LOL then
begin
showmessage('i got 0wnz0rd');
windows.beep(9000, 9999999);


just to annoy the people who crack it Wink

I know what a crackme is and how to make one, regardless if I want it annyoing or not.

I'm more interested in encryption/code obsfucation techniques and cracking techniques so that I can beat them.

if you want a source code i just made a really basic one in vb 2005 express do whatever you want with it =P

first step: make a textbox i called mine txtPassword
second step: make a button i called mine btnOK

Public Class frmPassword
Const MyPassword As String = "hidden"
Public CorrectPassword As Boolean
Public RememberPassword As Boolean
Private Sub frmPassword_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.Show()
txtPassword.Text = ""
txtPassword.Focus()
End Sub

its pretty basic

Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
If txtPassword.Text = MyPassword Then
CorrectPassword = True
MsgBox("Correct Password")
Me.Close()
End If
If MsgBox("Incorrect Password") Then
CorrectPassword = False
End If
End Sub
End Class

it isnt that great but there is a source code (forcing you to use vb Laughing) and if you couldnt tell the password is hidden =p

that could be cracked in 10 seconds

i made a crackme with a stringtohex and then md5'ed the hex string "steve"

which is alot more detailed than yours

cracked in under 30 seconds >.>

Sherlock has arrived...

He just told everyone it's really basic one, and that's why he posted the src for it...

Why don't you post your md5 one, instead of bragging about making md5'ing it n all that? lol Idea
