如何使用自定义IPasswordHasher？

Question

我实现了IPasswordHasher

public class MyPasswordHasher : IPasswordHasher
{
    public string HashPassword(string password)
    {
        using (SHA256 mySHA256 = SHA256Managed.Create())
        {
            byte[] hash = mySHA256.ComputeHash(Encoding.UTF8.GetBytes(password.ToString()));

            StringBuilder hashSB = new StringBuilder();
            for (int i = 0; i < hash.Length; i++)
            {
                hashSB.Append(hash[i].ToString("x2"));
            }
            return hashSB.ToString();
        }
    }


    public PasswordVerificationResult VerifyHashedPassword(
      string hashedPassword, string providedPassword)
    {
        if (hashedPassword == HashPassword(providedPassword))
            return PasswordVerificationResult.Success;
        else
            return PasswordVerificationResult.Failed;
    }
}

我在IdentityConfig中写道

manager.PasswordHasher = new MyPasswordHasher();

但var user = await UserManager.FindAsync(model.Email, model.Password);在AccountController/Login中不要使用MyPasswordHaser.

我怎样才能在身份2.1中使用它？

Answer 1

您必须将其插入 UserManager：

public class AppUserManager : UserManager<AppUser, int>
{
    public AppUserManager(AppUserStore a_store)
        : base(a_store)
    {
        _container = a_container;
        _emailService = _container.GetInstance<IEmailService>();

        PasswordHasher = new AppPasswordHasher();
    }
}
