I have been reading about passwords and hashing algorithms and what not and decided to write a program.

Overview: The user should be prompted to create a password the first time the program is executed. They should enter a key and confirm it. If they have executed the program previously, then they should just enter the password to gain access.

I determine if the user has run the program by checking if key.txt exists. Is there a more preferred method?

I tried to streamline some code with the two bool functions. Any other suggestions for cleaner or more concise code?

#include <iostream>
#include <fstream>
#include <string>
#include "sha256.h"
using namespace std;

bool keyExists() 
 bool keyExists = false;
 ifstream inFile("key.txt");

 if (inFile) 
 keyExists = true;
 

 return keyExists;


bool isMatch(string key, string confirmKey) 

 bool match = false;
 if (key == confirmKey) 
 match = true;
 

 return match;


int main() 

 if (keyExists()) 
 string key;
 string storedKey;
 cout << "Please enter key: ";
 getline(cin, key);

 SHA256 sha256;
 ifstream inFile("key.txt");
 getline(inFile, storedKey);

 if (isMatch(sha256(key), storedKey)) 
 cout << "Acces Granted!n";
 
 else 
 cout << "Access Denied!n";
 
 

 else 
 string key;
 string confirmKey;

 cout << "Please create a key: ";
 getline(cin, key);
 cout << "Confirm key: ";
 getline(cin, confirmKey);

 if (isMatch(key, confirmKey)) 

 SHA256 sha256;
 ofstream outFile("key.txt");
 outFile << sha256(key);
 

 else 
 cout << "Keys do not match!n";
 
 

 return 0;

Many thanks to Stephan Brumme for the awesome hashing algorithm code! This was very easy to implement.
