Crack Me (Testing weird password thing) Please Help

[htaed]

Right, well it could be the stupidest thing i have ever done, but i just wanted to test it anyway, so a few months ago i released a simple crackme program in c++ to see if anyone could find out the password, many people did,

So i've written a very strange way of calculating if the password is correct, i will tell you how it is done if someone cracks it, it shouldn't be to hard, just post the code given to you after the password was entered correctly.

Erm... What does this mean......

You fucking cheatzor don't tell anyone the secret codez :P

Edit: I used my app made in vb to semi-decompile it...

 

[htaed]

Thats not it its just a joke i put in for people that tried what you did, the code is stated quite clearly

 

[iHem]

run time error

EDit got it working lol secret code = R o C K E t M a n z W i n t e h G a m e r

 

[htaed]

don't do what you did then

 

[Visual Basic Matt]

Yea, Runtime error for me... I think i had the right pass cause it said runtime error when i put it in otherwise its wrong pass...

Edit: Yep, Nvm I got it.... I had it right cause when i decompiled i came up with that weird thing then scrolled down a bit and found this R o C K E t M a n z W i n t e h G a m e r

Same as ihem

Ok i am just writing how it works, good job.. can you say how you did it, so maybe i can try to make a more secure one and challange you devils some more

So it works like this, there are 6 textboxes at the bottom, every time you press a key in the password box, it puts the keyascii of the button you pressed in the textboxes at the bottom, for the first six then it starts again, then it does this sum

sum = 0
sum = Text2.Text
sum = sum + Text3.Text
sum = sum + Text4.Text
sum = sum + Text5.Text
sum = sum + Text6.Text
sum = sum + Text7.Text
sum = sum * 4
sum = sum - 60
sum = sum / 90

Then the result of that is checked to another sum, and only if a boolean is set to true, which is set at true when six keys are pressed

Private Sub Command1_Click()
If Text8.Text = 12 + 10 - 2 + 4 + 4 And resone = True Then
MsgBox "Correct: Secret Code = RoCKEtManzWintehGamer"
Else: MsgBox "Wrong Password"
End If
End Sub

Too easy. I cracked it the old fashion way.

Any 6+ combination will get you access.

I made my own after I did this one...

Can anyone get the final code after beating all 3 levels?

-Sorry kinda hijacked your thread but i didn't see any point in making another when this has the same topic. (Its just basically a reply...)

What does this actually do?

 

[Jazz00006]

Nothing. It's just a way for people to test their programs and see if anyone can 'crack' them.

And VB Matt. Your program shows all of its 'passwords' when viewed with a hex editor, or even notepad.
Try not to store passwords in plain text.

 

[Visual Basic Matt]

I know... Thats just the numbers used to figure out the actual password your need to devide, add, using the numbers given. Try every possibility until you get the password....

 

[Jazz00006]

I don't have to

Your original (compiled) code looks something like this

See that highlighted part, ... JE ... that simply put, means jump if equal to. (If X = true then)


If we get rid of that if statement, we get something like this

And if we compile that and run it, we have something that doesn't require any input to equal true.

Repeat for all 3 and your 'try all the possibilities' becomes nothing.

Hey, whats that program... I've saw it before but don't recall what it is... I want to use it to figure out how some stuff works.... I bet, i could learn a lot from using that.

OllyDbg. It is a debugger. Trust me, you can't just pick up and learn ASM in a matter of weeks like some languages.

I agree with you!
