Projects and Discussion / Re: problem with a project in c++
« on: August 13, 2015, 04:54:55 pm »
Thank you for the advice 
.
So, the problem is that i get a bug even if i delete the letter at position .
the bug is that the console prints out only 4 letters instead of 7.
*I did as you advised (advice 1) now it prints out different string size each time.
.So, the problem is that i get a bug even if i delete the letter at position .

Code: [Select]
using namespace std;
int main()
{
string inputWord("MYSTERE"); // I wanted to test it with 1 word before generalizing it
string shuffledWord;
const int wordSize(inputWord.size());
for (int i=0 ; i <= wordSize ; i++)
{
int position(0) ;
srand(time(0));
position = rand() % wordSize;
shuffledWord += inputWord[position];
inputWord.erase(position, 1);
}
cout << "shuffled word :" << shuffledWord<<endl;
return 0;
}

Hello guys,
I have been learning c++ alone for a week now (not very impressive i know) .
I have been trying to create a function that takes a string as input and shuffles the order of the string without repeating any of the characters.
It is part of a bigger program that is basically a guessing game between two players :
player 1 inputs a word >> computer shuffles the word >> computer prints shuffled word >> player 2 needs to guess what was the original word and input it .
i cant figure out what the problem is
Moreover I would like to know if you could possibly give me some feedback about my style (what can I improve)
(By the way its not a function yet because i needed to test it)
Thanks

#include <iostream>
#include <string>
#include <ctime>
#include <cstdlib>
/*
this function takes a string as argument and shuffles it */
using namespace std;
int main()
{
string inputWord("MYSTERE"); // I wanted to test it with 1 word before generalizing it
string shuffledWord;
for (int i=0 ; i <= inputWord.size() ; i++)
{
int position(0) ;
srand(time(0));
position = rand() % inputWord.size();
shuffledWord += inputWord[position];
inputWord.erase(5, 1); // Retire la lettre n°5
}
cout << "shuffled word :" << shuffledWord<<endl;
return 0;

Security in the CPU itself ?
Do you mean that it has security in the gate transistors or/and in the logic circuit ?

Thanks for the info ande .
I got alot more questions but I think I can continue this one on google

« on: December 03, 2013, 07:35:49 pm »Entropy ? (again sorry for the noobness )
Do you mean that by definition a password becomes more complex and has many layers of change til it becomes a hash ? and by collision do you mean that there can be a recognizable pattern how the entropy develops , and by that the computer arrives at a conclusion as to what the original password or the prime number was ?
(by the way i love this forum lots of smart peoples here , its refreshing to see that it still exists in the internet

Its a really interesting subject.
But if peoples do it successfully ,can lets say sha-256 be still secure ? because its still
(2^64 ) -1 possible combinations and with a few asic chips and doing some parallel hashing peoples could brute force hashes pretty quick no ?

Yes I tought of parallel computing ,but (sorry for the noobnes here ) is it possible to divide a hash by segment like so : core 1 does "2j" core 2 does "h2".. etc
Or just lets say : core 1 does lowercase core 2 : uppercase ...etc

ok..so no brute forcing for me I guess 
.
Thanks for the help anyways

ok thanks..would it be just modifications in the driver ?

What i meant is using it to brute force any regular password lets say

Hi Guys ,
I started to get interested in Cryptocurrency mining and the basic concept ( I guess most of you allready know ) is that you find a solution to a hash a bit like brute forcing , now miners figured out that actually GPU's (and later technology witch are asic chips that run at +- 500 gigahash /s instead of CPU's witch work at max 1 megahash/s ) are alot faster at solving this kind of problems than CPU's are .
My question is : would it be faster to brute force a hash with CPU or GPU for anything ?

Thank You

well its not that wild since i do the same thing on my network...so its one of the possibilities that he should check so yea its an educated guess like i said.
but definitely not a wild one .

i would guess its a mac adress filtering..(again its an educated guess)
