why i hash same password，result unchanged？

[Jerry-Lam]

I running your library on wsl2 unbutu 22.04.1

#include "bcrypt.h"
#include <iostream>
int main()
{

    std::string password = "123456";

    std::string hash = bcrypt::generateHash(password, 12);

    std::cout << "Hash: " << hash << std::endl;

    return 0;
}

Seems not auto-gen a salt
