Build your own cryptographically safe server/client protocol

, 21 Jun 2006
This article presents all you need to implement your own secure protocol using variable keysize RSA encryption/decryption, digital signing, multi precision library, Diffie-Hellman key exchange, Rijndael, and more. Everything is converged into a secure IOCP client/server chat server.
// RanDialog.h : header file

// CRanDialog dialog
#include "stdafx.h"
#include "SecureChat.h"
#include "MyCryptLib.h"
#define _POOL_SIZE_ 624*4
#ifndef _RANDOMDIALOG_21343434SLDKLSSDDUYGD6783676323jdjsdj
#define _RANDOMDIALOG_21343434SLDKLSSDDUYGD6783676323jdjsdj

class CRanDialog : public CDialog
// Construction
	BYTE m_raw_pool[_POOL_SIZE_];

	CRanDialog(CWnd* pParent = NULL);   // standard constructor

	void stir_it(unsigned int);

// Dialog Data
	enum { IDD = IDD_RANDOM };
	CProgressCtrl	m_cProgress;

// Overrides
	// ClassWizard generated virtual function overrides
	virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV support

// Implementation
	int m_times_around;
	int m_max_times_around;
	int m_raw_pool_ptr;
	// Generated message map functions
	afx_msg void OnMouseMove(UINT nFlags, CPoint point);
	virtual BOOL OnInitDialog();
	afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
