answer:The first function (FUN_00082750) appears to be a calculation of a weighted value from a string. It initializes a weighting factor to 1 and then iterates through each character of the string in reverse order, calling the second function (FUN_00082657) to get the value of each character, and the third function (FUN_0008269b) to convert the character to a numerical value. The weighting factor is multiplied by the numerical value and added to the result. The weighting factor is doubled in each step. I would suggest the following function signature for this function: ```c int calculate_weighted_value(const char *str); ``` The second function (FUN_00082657) appears to return the length of the string. It iterates through the string until it encounters a NULL byte (0x00) and returns the length of the string. I would suggest the following function signature for this function: ```c size_t string_length(const char *str); ``` The third function (FUN_0008269b) seems to be a character-to-number conversion. It takes a single character input as an argument and converts it to a number based on whether it is a digit (0-9), an uppercase letter (A-Z), or a lowercase letter (a-z). For digits, it returns the corresponding number (0-9), for uppercase letters, it returns the corresponding number (10-35), and for lowercase letters, it returns the corresponding number (36-61). If the input is not a digit or letter, it returns 0. I would suggest the following function signature for this function: ```c int char_to_number(char c); ``` The global (or static) values in these functions can be named as follows: - For FUN_00082750: - local_2c: `input_str` - local_20: `weight` - local_28: `str_length` - local_24: `result` - local_1c: `weighted_value` - For FUN_00082657: - local_28: `input_str` - local_24: `current_position` - local_20: `last_position` - local_1c: `length` - For FUN_0008269b: - local_20: `input_char` - local_1c: `num_value`

question:как сделать авторизацию и регистрацию через identity сохранять пароли в БД

answer:Для реализации авторизации и регистрации через Identity в .NET Core и сохранения паролей в базе данных, необходимо выполнить следующие шаги: Шаг 1. Добавление пакетов NuGet Установите следующие пакеты NuGet (если они не установлены): Microsoft.EntityFrameworkCore Microsoft.AspNetCore.Identity.EntityFrameworkCore Шаг 2. Добавление контекста базы данных Создайте класс контекста базы данных, который будет использоваться для хранения информации об учетных записях пользователей. Этот класс должен наследоваться от класса IdentityDbContext<User>, где User - класс, описывающий учетную запись пользователя. В данном случае предполагается использование базы данных SQL Server. Пример кода: ``` using Microsoft.AspNetCore.Identity.EntityFrameworkCore; using Microsoft.EntityFrameworkCore; public class ApplicationDbContext : IdentityDbContext<User> { public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options) { } } ``` Шаг 3. Добавление настроек ASP.NET Identity Откройте файл Startup.cs и добавьте следующие настройки: ``` using Microsoft.AspNetCore.Identity; public void ConfigureServices(IServiceCollection services) { // Добавляем контекст базы данных services.AddDbContext<ApplicationDbContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection"))); // Настраиваем ASP.NET Identity services.AddIdentity<User, IdentityRole>(options => { // Настройки пароля options.Password.RequireDigit = true; options.Password.RequireLowercase = true; options.Password.RequireNonAlphanumeric = true; options.Password.RequireUppercase = true; options.Password.RequiredLength = 8; options.Password.RequiredUniqueChars = 1; // Настройки блокировки учетных записей options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30); options.Lockout.MaxFailedAccessAttempts = 5; options.Lockout.AllowedForNewUsers = true; // Настройки пользовательского интерфейса options.User.AllowedUserNameCharacters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-._@+"; options.User.RequireUniqueEmail = true; }) .AddEntityFrameworkStores<ApplicationDbContext>() .AddDefaultTokenProviders(); services.ConfigureApplicationCookie(options => { // Настройки cookie для аутентификации options.Cookie.HttpOnly = true; options.ExpireTimeSpan = TimeSpan.FromMinutes(30); options.SlidingExpiration = true; }); } ``` Шаг 4. Создание класса User Создайте класс User, который будет описывать учетную запись пользователя: ``` public class User : IdentityUser { } ``` Шаг 5. Добавление миграций и обновление базы данных Добавьте миграцию командой `Add-Migration InitialCreate` в консоли диспетчера пакетов. Затем обновите базу данных командой `Update-Database`. Шаг 6. Создание контроллеров Создайте контроллеры для регистрации и аутентификации пользователей. В примере ниже используется стандартная реализация методов: ``` using Microsoft.AspNetCore.Identity; using Microsoft.AspNetCore.Mvc; using System.Threading.Tasks; public class AccountController : Controller { private readonly UserManager<User> _userManager; private readonly SignInManager<User> _signInManager; public AccountController(UserManager<User> userManager, SignInManager<User> signInManager) { _userManager = userManager; _signInManager = signInManager; } [HttpGet] public IActionResult Login() { return View(); } [HttpPost] public async Task<IActionResult> Login(LoginViewModel model, string returnUrl = null) { returnUrl ??= Url.Content("~/"); if (ModelState.IsValid) { var result = await _signInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, lockoutOnFailure: false); if (result.Succeeded) { return LocalRedirect(returnUrl); } if (result.IsLockedOut) { return RedirectToAction(nameof(Lockout)); } else { ModelState.AddModelError(string.Empty, "Неверный логин или пароль."); return View(model); } } return View(model); } [HttpGet] public IActionResult Register() { return View(); } [HttpPost] public async Task<IActionResult> Register(RegisterViewModel model, string returnUrl = null) { returnUrl ??= Url.Content("~/"); if (ModelState.IsValid) { var user = new User { UserName = model.Email, Email = model.Email }; var result = await _userManager.CreateAsync(user, model.Password); if (result.Succeeded) { await _signInManager.SignInAsync(user, isPersistent: false); return LocalRedirect(returnUrl); } foreach (var error in result.Errors) { ModelState.AddModelError(string.Empty, error.Description); } } return View(model); } [HttpPost] [ValidateAntiForgeryToken] public async Task<IActionResult> Logout() { await _signInManager.SignOutAsync(); return RedirectToAction(nameof(HomeController.Index), "Home"); } [HttpGet] public IActionResult Lockout() { return View(); } } ``` Шаг 7. Создание представлений Создайте представления для регистрации и аутентификации пользователей: Login.cshtml: ``` @model LoginViewModel <h2>Вход на сайт</h2> <form asp-action="Login"> <div asp-validation-summary="All" class="validation-summary-valid text-danger"></div> <div class="form-group"> <label asp-for="Email"></label> <input asp-for="Email" class="form-control" /> <span asp-validation-for="Email" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="Password"></label> <input asp-for="Password" class="form-control" /> <span asp-validation-for="Password" class="text-danger"></span> </div> <div class="form-group form-check"> <input asp-for="RememberMe" class="form-check-input" /> <label class="form-check-label" asp-for="RememberMe">Запомнить меня</label> </div> <button type="submit" class="btn btn-primary">Войти</button> </form> ``` Register.cshtml: ``` @model RegisterViewModel <h2>Регистрация</h2> <form asp-action="Register"> <div asp-validation-summary="All" class="validation-summary-valid text-danger"></div> <div class="form-group"> <label asp-for="Email"></label> <input asp-for="Email" class="form-control" /> <span asp-validation-for="Email" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="Password"></label> <input asp-for="Password" class="form-control" /> <span asp-validation-for="Password" class="text-danger"></span> </div> <div class="form-group"> <label asp-for="ConfirmPassword"></label> <input asp-for="ConfirmPassword" class="form-control" /> <span asp-validation-for="ConfirmPassword" class="text-danger"></span> </div> <button type="submit" class="btn btn-primary">Зарегистрироваться</button> </form> ``` Шаг 8. Запуск приложения Запустите приложение и перейдите на страницу входа или регистрации. После успешной регистрации и аутентификации вы должны быть перенаправлены на главную страницу.
