No Patch allowed, there isn't protection...

KM1 uses a function for calculating a 64bits hash...
Suggestions:
Message to obtain for right user/serial contains the word "nice" (without ").

Bruteforce hash function, after, generate a valid user/serial couple (or build a keygen) will be really easy.

(Sorry for my bad english...)
Good luck!

hey tell me please how scanf("%llu",..) is supposed to work ? if i enter 64 bit digit it doesnt work it fill only first part of digit. I dont know if this is my system depented or not.
For example if i enter
17793993638370666473
which is
F6F0F6EFFEA4E7E9 =
= F6F0F6EF FEA4E7E9


only FEA4E7E9 is wrote to the buffer, and 2nd part stays 00000000.

Hey guys... the %llu directive that i used in making this crackme is dependent of mingw... You can patch the executable for using %I64u (%llu stand for long long unsigned int - 64bits unsigned integer) instead of %llu if you don't have mingw on your pc... Sorry for the bug...

I dunno if it will be possible, but for sure bruteforce this is very fast, so imho it is useless to do something else.
