I also had to change the hashing method too

EnhancedHashPassword()

EnhancedHashPassword()

HashPassword()

HashPassword()

. It works, thank you 🙂

✅ Hashing password - ASP.NET Core Identity PasswordHasher

Thank you !! I don't get how to use Identity reading the code source of it, I'm a begginer, and C# is hard without the proper documentation 😢 I don't want to use it manually. I'm trying to use the whole framework, but I'm having a hard time! Here what I'm trying to do. I would like to hash the passwords of my users, when users create an account. And then to use it for the authentication part of the application.

✅ Hashing password - ASP.NET Core Identity PasswordHasher

Here my implementation on the Program.cs :

builder.Services.AddDefaultIdentity<User>().AddUserStore<DbNetflimContext>();

builder.Services.AddDefaultIdentity<User>().AddUserStore<DbNetflimContext>();

I installed 2 more NuGets : Microsoft.AspNetCore.Identity.EntityFrameworkCore and Microsoft.AspNetCore.Identity.UI

✅ Hashing password - ASP.NET Core Identity PasswordHasher

Hi @TeBeCo , I still have trouble using Identity, if you want to take a look... Here my post request :

[Route("api/[controller]")]
[ApiController]
public class UsersController(DbNetflimContext context, PasswordHasher<User> passwordHasher) : ControllerBase
{
    private readonly DbNetflimContext _context = context;
    private readonly PasswordHasher<User> _passwordHasher;
[...]

[HttpPost]
public async Task<ActionResult<User>> PostUser(User user)
{ 

    Console.WriteLine($"Mot de passe avant hachage : {user.PasswordUser}");

    user.PasswordUser = _passwordHasher.HashPassword(user, user.PasswordUser);

    Console.WriteLine($"Mot de passe après hachage : {user.PasswordUser}");

    _context.Users.Add(user);
    string jsonString = JsonSerializer.Serialize(user);
    _context.Users.Add(user);
    try
    {
        await _context.SaveChangesAsync();
    }
    catch (DbUpdateException)
    {
        if (UserExists(user.UserId))
        {
            return Conflict();
        }
        else
        {
            throw;
        }
    }

    return CreatedAtAction("GetUser", new { id = user.UserId }, user);
}

[Route("api/[controller]")]
[ApiController]
public class UsersController(DbNetflimContext context, PasswordHasher<User> passwordHasher) : ControllerBase
{
    private readonly DbNetflimContext _context = context;
    private readonly PasswordHasher<User> _passwordHasher;
[...]

[HttpPost]
public async Task<ActionResult<User>> PostUser(User user)
{ 

    Console.WriteLine($"Mot de passe avant hachage : {user.PasswordUser}");

    user.PasswordUser = _passwordHasher.HashPassword(user, user.PasswordUser);

    Console.WriteLine($"Mot de passe après hachage : {user.PasswordUser}");

    _context.Users.Add(user);
    string jsonString = JsonSerializer.Serialize(user);
    _context.Users.Add(user);
    try
    {
        await _context.SaveChangesAsync();
    }
    catch (DbUpdateException)
    {
        if (UserExists(user.UserId))
        {
            return Conflict();
        }
        else
        {
            throw;
        }
    }

    return CreatedAtAction("GetUser", new { id = user.UserId }, user);
}

I have 500 error from the frontend, I never enter the post request. And I have this issue:

System.InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.PasswordHasher`1[ToDoAPI.Models.User]' while attempting to activate 'ToDoAPI.Controllers.UsersController'.

System.InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNetCore.Identity.PasswordHasher`1[ToDoAPI.Models.User]' while attempting to activate 'ToDoAPI.Controllers.UsersController'.

I can't implement correctly the dependance in the Program.cs

✅ Hashing password - ASP.NET Core Identity PasswordHasher

Thank you 🙂 I often can't find what I want with Microsoft's documentation... Like, here, I have some infos about Identity methods but no examples for how I have to use them. Do I have to use

public virtual string HashPassword (TUser user, string password);

public virtual string HashPassword (TUser user, string password);

directly in my model ? Or in the controller ? I'm lost ^^
