However, it is easier to try without even looking inside.
Thanks for that, it was nice !

TyfoC on 7:52 AM 05/25/2023: Okay, it was very interesting and not easy (~20-30m))
So, login length must be at least 6 characters, password is reversed login.
Reconstructed CheckPassword(const char*, _BYTE*):
#include
#include
// login - any string
// password - reversed login
bool CheckPassword(const char* login, const char* password) {
int length = (int)strlen(login);
if (length = 6 !
std::cout

volts on 12:04 PM 06/12/2023: My third crackme, went pretty smoothly, ended up debugging the CheckPassword method instead of trying to understand it.
I actually solved this before I even disassembled it, the first thing I tried was login = "a" and password = "asdfgh", which actually works because of a bug in this method.
