Crack_Me V1 (Easy to Medium difficulty)

[bkRy]

Hello bkRy here,

so yesterday I saw a "Crack Me" made by Mezmaa and I decided to make one myself, so here it is!

What do you need to find?
->You have to find the "correct" key_s to get access.

!If you are going to post the "answer" + !explanation!, please put it into a spoiler tag!

I will post the code of the whole programm since both of those scans are getting false-positives... Just in case you wanna compile it yourself
Don't cheat by looking at the code!

 

#include <windows.h>
#include <iostream>
#include <random>
#include <time.h>

bool isKeyPresent = FALSE;
unsigned int inputKey;

int main(){
	SetConsoleTitle("Crack_Me-MPGH v1 - by bkRy");
	std::cout << "\t\t\tCrackeMe v1 by bkRy" << std::endl;

#pragma region math
	int tempSerial;

	
		srand(time(NULL));
		//getting rand. values with <time.h>
		unsigned int x = rand();
		Sleep(30);
		unsigned int z = (rand()) + x;
		Sleep(30);
		unsigned int y = (rand()) + x;
		Sleep(30);
		unsigned int multiX = 15;
		Sleep(30);
		//done getting rand. values, should be big enough to make a "good" key				


		unsigned int q = z*((x + y)*(x + y));
		unsigned int p = x*((x - y)*(x - y));
		unsigned int multi = y / multiX;

		tempSerial = (((((q - p) + multi))*(x / 10)) / x); //all that should equal https://prntscr.com/d21km1
		tempSerial += tempSerial;				



		if (tempSerial > 2){
			isKeyPresent = TRUE;
		}
		else{goto end;} //prevent no key "cracks"

		rtry: //could have placed the rtry on 45, but to prevent cracks lets put it up here
		if (isKeyPresent == TRUE){	
			std::cout << "What is the Key?\n" << "Key: ";
			std::cin >> inputKey;

			if (inputKey == tempSerial){
				std::cout << "\nCongratulations!\nPlease leave a 'thanks' on my profile if you enjoyed it!" << std::endl;
				Sleep(5000);
				goto end;
			}if (inputKey != tempSerial){
				std::cout << "Wrong key...\nTry again!" << std::endl;
				Sleep(700);
				system("cls");
				std::cout << "\t\t\tCrackeMe v1 by bkRy" << std::endl;
				goto rtry;
			}


		}	
		
		if (isKeyPresent == FALSE){goto end;} //prevent no key "cracks"
#pragma endregion

	return 0;
}

//EDIT forgot to compile file in Release mode, uploaded it new + virustotal updated
