Code:
00403713   > \8B55 80       MOV EDX,DWORD PTR SS:[EBP-80]
00403716   .  52            PUSH EDX
00403717   .  68 241D4000   PUSH Crackme.00401D24                    ;  UNICODE "IIF8 127F7F121G"
0040371C   .  FF15 3C104000 CALL DWORD PTR DS:[<&MSVBVM60.__vbaStrCm>;  MSVBVM60.__vbaStrCmp


Code that is nothing more then:

Code:
If Text1.Text = "IIF8 127F7F121G"


Is not secure lol. As you can see from the fast responses. If you want to make some better crackmes, come up with some ways to hide your strings, avoid using if then compares if possible, etc.

Fuck you, It's been awhile since I programmed, I tried using my own encryption to hide it, I didn't know the program would be retarded enough to have 2 from one passwords...

The real one is "hi peeps" Try it. -.-''

Easiest way to do that would be to make an encryption method, make the thing decrypt it, then check if the decrypted version is the password.


That will leave the password vulnerable during the time to compare the passwords.

Or do the opposite and encrypt the entered text then compare it to the encrypted password.

this is not good at all cause when you debugging it you will see the password like an exe compressor you will come to see the real program.

this is good but decryption is always possible[/code]
