Introdução

A classe QCryptographicHash provê um modo de gerar hashes de criptografia, podendo ser usada para hashes de criptografia de binários ou de dados de textos.

Este criptografia é usada quando você deseja enviar alguma informação de um modo seguro. O texto criptografado é chamado de texto chiper.

Pré-requisitos

  • Baixe e instale a versão atual do Qt para Symbian segundo as instruções deste artigo.

Algumas funcionalidades relacionadas

  • Adiciona às informações hashes de criptografia.
QByteArray string="Nokia";
hash->addData(string);
  • Retorna o valor hash final.
QByteArray string1=hash->result();

Código fonte

Main.cpp

#include <QtGui/QApplication>
#include "textcodec.h"
#include<QWidget>
#include<QHBoxLayout>
#include <QCryptographicHash>
#include<QString>
#include<QByteArray>
#include<QLabel>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QWidget *win=new QWidget();
QHBoxLayout *lay=new QHBoxLayout();
QLabel *lbl=new QLabel();
QLabel *lbl1=new QLabel("Encrypted Text:");
lbl1->setBuddy(lbl);
QByteArray string="Nokia";
QCryptographicHash *hash=new QCryptographicHash(QCryptographicHash::Md4);
hash->addData(string);
QByteArray string1=hash->result();
lbl->setText(string1);
lay->addWidget(lbl1);
lay->addWidget(lbl);
win->setLayout(lay);
win->setStyleSheet("* { background-color:rgb(199,147,88); padding: 7px ; color:rgb(255,255,255)}");
win->showMaximized();
return a.exec();
}
