  • Hello today I will show you guys how to crack programs with Ollydbg. I recommend using notepad to write down the key
    1) Open Ollydbg and load the crackme.
    2) Right click in the code area 'Search for - All intermodular calls'.
    3) Click 'Destination' to sort by type.
    4) Type or look for 'user32.GetDlgItemTextA' notice there are two of them (Username, Reg. code),
    5) Set a breakpoint (F2) on both, and close the 'Found intermodular calls' window.
    6) Run the application from Ollydbg (F9).
    7) Type in your 'Username' and a random 'Reg. code'. Click 'Check it!'.
    8) The breakpoint will stop on the first 'GetDlgItemTextA' which is your 'Username', there's nothing you need from this section (but always set a break just in case).
    9)Press F9 to continue running the application.
    10)It will immediately break again for your 'Reg. code'.
    11)Step through the application (F8), you will only need to do this once you will be brought to
    'String2', This is your correct 'Reg. code' for your 'Username', if you notice below it in
    'String1' your random 'Reg. code'. Theres no need to go any further.
    12)Close out of Ollydbg
    14)Reopen Crackme and input the correct information.
