Doesn't even run. Confused

But I looked without running it.

Code:

int __cdecl ENCRYPTION(int a1)
{
signed int v1; // eax@1
int v2; // ecx@1
int v3; // esi@1
int v5; // ecx@1

v5 = (a1 + 4) << 16;
v2 = (a1 << 16) + (v5 & 0xFF0000);
v1 = 0;
v3 = 0;
while ( v3 <= a1 )
v1 %= v3++ + 3;
return v2 + 5;
}

thats the hashing encryption

answer =

Code:

char v0[] = "Enter password: - ";
char i0[260]; //input
int i1;
printf("%s", v0);
gets_s((char *)i0, 260);
i1 = atoi((const char *)i0);

if ( ENCRYPTION(whatYouInput) == 1048581 ) {
char v1[] = "WIN :3";
printf("%s", v1);
getchar();
} else {
char v2[] = "Fail :<";
printf("%s", v2);
}
return 0;

So if whatever you input and you pass the encryption correctly and get a result of 1048581 then you get message

"WIN :3"

Anyways here i written a attack to find passwords

Code:

int main(int argc, char* argv[])
{
printf("Running brute forcer!\n");
for(int i = 0;i < 0xFFFFFFFF; i++) {
   if(ENCRYPTION(i) == 1048581) {
      printf("%d", i);
   }
}
return 0;
}

generated answers seem to be
in decimal

6
65414
65542

in ascii

6Au*
6Bu*
6Cu*
etc..

but i still can't even run the program lolz

What? why would you bruteforce that? that's plain stupid.
you have the encryption routine in front of your eyes.

Code:

v5 = (a1 + 4) << 16;
v2 = (a1 << 16) + (v5 & 0xFF0000);

everything else is crap, since it returns v2+5 anyway.

yah but v2 has v5 and a1 in it.. but yes seems return comes out to be 5+1.. or something similar to that. because answers start with 6.
