ReWrit, please change the pause>null statement. You will create a file called null instead of pipelining to nul.

But even better, replace it with getch() or getchar(). Or if you are writing C++, please use cin.get().

Thanks in advance!

ok i will in my comming crackmes.

I didn't see nothing new in this crackme.
You still get username length, do some calculation, get number and compare this number with entered text.

how do i do the internal keygen? i think this may be too hard for me lol
16. Oct 2008
Calculating a password is pretty easy (as already mentioned), here a little pseudo code:
pass = strlen(name)
pass = 3*pass
pass = pass shl 2
pass = pass^3
pass = pass + 23
pass = pass + pass * 708224
