| can you say what compiler you've used? And am I supposed to get a string for a right flag? So far I've only found "Invalid" |
==> |
| it boils down to
if ( (unsigned int)(calc_value2 - 0x8D24D00) = 0xF4240 )
result_flag = "Invalid flag!";
I see that the calculation itself was already mentioned above..
a few more keys:
ZXINzDNniEkOvS
CevXPjscYmPOSh
CevXPjscYmPOSh
SePSvWbGRPoQpQ
twciiDbxPPyvtW

| a few valid keys (there are much more):
also keys do not have to be in the format XXXX-XXXX-XXXX-XXXX,
for instance both AAAABDEBBVMCGIGNQVE and 0000314806631749367 are valid keys.

| good crackme, there are multiple solutions, some consisting only of letters, others only of numbers |
==> |
| 557746729 hardcoded |
==> |
| password is 41 from rand() % 1000, i though rand() was supposed to return a different value for every execution, but whatever |
==> |
| very nice and simple |
==> |
| you have to look at the debugger to get the values, since you are using random numbers, even though you modulus it to 10000 there's still no "fixed" solution |
