    Crack Me (Testing weird password thing) Please Help

    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.

    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 :D

    [​IMG]
    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
    Code:
    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
    Code:
    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... :p
    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...)

    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.

    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....

    I don't have to :D

    Your original (compiled) code looks something like this
    [​IMG]

    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
    [​IMG]


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



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

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