md5实现对用户名与密码的保护
这里我们说一下关于如何运用md5算法实现对用户名与密码的保护。
我们都知道，有一些应用程序需要以用户名与密码登录应用程序时，在应用程序后台就需要一个保存用户名与密码的数据库。这类数据库有，数据库，文件，服务器云台等。
我们为了更好的让大家理解md5算法保护重要信息，所以我们这里选用文件来作为用户名与密码存储空间。
下面先设计UI，分别添加如下对话框：
- 主对话框：
- 登录对话框：
- 注册对话框：
- 用户信息存储文件名称： NamePassword.cfg
- 这打开应用程序时，主对话框首先判断是否需要创建存储文件：
CFile fileNamePwd; fileNamePwd.Open(_T("NamePassword.cfg"), CFile::modeRead); if ((int)fileNamePwd.m_hFile < 0) { fileNamePwd.Open(_T("NamePassword.cfg"), CFile::modeCreate); } fileNamePwd.Close(); CFobsignupDlg::OnOK(); LoginDlg loginDlg; loginDlg.DoModal();
如果文件不存在，则创建一个文件。
- 在登录对话框中添加登录事件：读取文件内容--md5计算输入内容，比较计算结果与文件内容，如果相同，则输入正确，否则失败：
BN_Clicked_Loginvoid LoginDlg::BN_Clicked_Login() { // TODO: Add your control notification handler code here unsigned char verify[17] = { 0 }; unsigned char my_cfg[17] = { 0 }; unsigned char*pStr; unsigned int length; int i; CString str; UpdateData(true); if (m_Edit1_userName.IsEmpty()) { MessageBox(_T("Please enter your name.")); GetDlgItem(IDC_EDIT1)->SetFocus(); return; } if (m_Edit2_passwords.IsEmpty()) { MessageBox(_T("Please enter your password.")); GetDlgItem(IDC_EDIT2)->SetFocus(); return; } HMODULE hmd5; hmd5 = ::LoadLibrary(_T("md5_dll.dll")); if (hmd5) { MD5 md5_computeHash = (MD5)::GetProcAddress(hmd5, "md5_ComputeHash"); str = m_Edit1_userName + m_Edit2_passwords; pStr = (unsigned char*)(LPCTSTR)str; length = str.GetLength(); md5_computeHash(pStr, length, verify); } else { MessageBox(_T("Lost md5_dll.dll,Please Reinstall.")); return; } ::FreeLibrary(hmd5); CFile cfile; cfile.Open(_T("NamePassword.cfg"), CFile::modeRead); if ((int)cfile.m_hFile < 0) { MessageBox(_T("Lost configuration file,please Reinstall.")); return; } i = 1; while (cfile.Read(my_cfg, 16)) { if (!strcmp((char*)my_cfg, (char*)verify)) { i = 0; break; } } cfile.Close(); if (i == 1) { MessageBox(_T("user name or passwords are invalid.")); return; } if (g_bool_symbol == false) { g_bool_symbol = true; LoginDlg::OnOK(); CFobsignupDlg dlgApp; dlgApp.DoModal(); g_bool_symbol = false; } }
我们比较内容运用 strcmp ，所以数组申明一定要以NULL /0作为结束，否则该比较永远为真。
- 注册对话框添加提交事件：输入用户名、密码内容md5计算，计算结果写入文件：
BN_Clicked_Submit
void RegisterDlg::BN_Clicked_Submit() { // TODO: Add your control notification handler code here CFile cfile; unsigned char output[16], *pdata; CString str, str2, str3; GetDlgItem(IDC_EDIT1)->GetWindowText(str3); GetDlgItem(IDC_EDIT2)->GetWindowText(str2); if (str3.IsEmpty())return; if (str2.IsEmpty())return; cfile.Open(_T("NamePassword.cfg"), CFile::modeWrite); if ((int)cfile.m_hFile > 0) { //get dll file module HMODULE hml = ::LoadLibrary(_T("md5_dll.dll")); if (!hml)return; //get dll interface's name MD5 md5_computeHash = (MD5)::GetProcAddress(hml, "md5_ComputeHash"); //get all of the user's information str = str3 + str2; // a poniter to string pdata = (unsigned char*)(LPCTSTR)str; md5_computeHash(pdata, str.GetLength(), output); cfile.Write(output, 16); cfile.Close(); //free dll file module ::FreeLibrary(hml); str = _T("Regiter OK.\r\nName:") + str3 + _T("\r\nPasswords:") + str2; MessageBox(str); //switch to login dlg RegisterDlg::OnOK(); LoginDlg dlgApp; dlgApp.DoModal(); } else { MessageBox(_T("Lost configuration file.please reinstall.")); } }
文件写入后，直接跳转到登录对话框。
