Too fucking easy, Joe:


I even provided proof that I actually (*cough*Warrior, Sidoh*/cough*) cracked it.

GJ Rabbit. You win~

Basically, I was checking to make sure the data was still the data, which is why you see a hash a bit above the string in Rabbit's picture.

Code Select Expand

Private Const Data As String = "You can't crack me!"
Private SHA As New clsSHA

Private Sub Form_Load()
    Me.Show
    If UCase(SHA.SHA256(Data)) = "2406C920A8F66582F85F78F98E38B7A7C34036B20EC1BD3C70FA04100C719BC3" Then
        Print Data
    Else
        Print "Try harder."
    End If
    If Command = "-show" Then MsgBox "Legit, tool."
End Sub

I used Crack_Me.exe -show to make sure it was the one I wrote. =)

Uh, this isn't any sort of protection. You need a hex editor, hell rabit replaced the "Try hander." instead of the Data string.

Rofl, forgot that he could just do that..

Dirty cheater, rabbi..t. =p

Easy!

iago@slayer:~/tmp$ ls -l Crack_Me.exe
-rw-r--r--  1 iago users 28672 2006-01-16 18:48 Crack_Me.exe
iago@slayer:~/tmp$ chmod +x Crack_Me.exe
iago@slayer:~/tmp$ echo 'echo "Joe sucks."' > Crack_Me.exe
iago@slayer:~/tmp$ ./Crack_Me.exe
Joe sucks.

Btw, you might want to think of more interesting ways to protect programs.  Unfortunately, I can't find the source for ones I've written, but they involved encrypting the message, and using a key generated to decrypt it.

Easy!

iago@slayer:~/tmp$ ls -l Crack_Me.exe
-rw-r--r--  1 iago users 28672 2006-01-16 18:48 Crack_Me.exe
iago@slayer:~/tmp$ chmod +x Crack_Me.exe
iago@slayer:~/tmp$ echo 'echo "Joe sucks."' > Crack_Me.exe
iago@slayer:~/tmp$ ./Crack_Me.exe
Joe sucks.

I hate to be a bitch, but according to your source code, there's absolutely no way it can say "Joe sucks".

Sure there is.  You open a hex editor (vi!) and change "Try harder" to "Joe sucks."
