私は古い.NETメンバーシップのアプローチでウェブサイトを既存している、今私は何をしたいのか、私はこのLinkを言及している暗号化されたパスワードをC＃でsqlハッシャパスワードを使用してプレーンテキストに変換する方法
新しいMVC .NETのアイデンティティアプローチに変換され、また、私はDBが新しいIDデシベルに変換しましたそれはすべて完璧に動作します。
しかし、の問題は、新しいパスワードが以前のパスワード .i.eで動作しないということです。パスワードでログインしようとしているときに、パスワードが間違っているというエラーが表示されます。
編集：ここで追加のコード
アプリケーションユーザーマネージャのコードは
public class ApplicationUserManager : UserManager<ApplicationUser>
{
public ApplicationUserManager(IUserStore<ApplicationUser> store)
: base(store)
{
}
//Added this constructor after reading microsoft blog https://docs.microsoft.com/en-us/aspnet/identity/overview/migrations/migrating-an-existing-website-from-sql-membership-to-aspnet-identity.
//except this constructor other codes are default which identity provides
public ApplicationUserManager()
: base(new UserStore<ApplicationUser>(new ApplicationDbContext()))
{
this.PasswordHasher = new SqlPasswordHasher();
}
public static ApplicationUserManager Create(IdentityFactoryOptions<ApplicationUserManager> options, IOwinContext context)
{
var manager = new ApplicationUserManager(new UserStore<ApplicationUser>(context.Get<ApplicationDbContext>()));
// Configure validation logic for usernames
manager.UserValidator = new UserValidator<ApplicationUser>(manager)
{
AllowOnlyAlphanumericUserNames = false,
RequireUniqueEmail = true
};
// Configure validation logic for passwords
manager.PasswordValidator = new PasswordValidator
{
RequiredLength = 6,
RequireNonLetterOrDigit = true,
RequireDigit = true,
RequireLowercase = true,
RequireUppercase = true,
};
// Configure user lockout defaults
manager.UserLockoutEnabledByDefault = true;
manager.DefaultAccountLockoutTimeSpan = TimeSpan.FromMinutes(5);
manager.MaxFailedAccessAttemptsBeforeLockout = 5;
// Register two factor authentication providers. This application uses Phone and Emails as a step of receiving a code for verifying the user
// You can write your own provider and plug it in here.
manager.RegisterTwoFactorProvider("Phone Code", new PhoneNumberTokenProvider<ApplicationUser>
{
MessageFormat = "Your security code is {0}"
});
manager.RegisterTwoFactorProvider("Email Code", new EmailTokenProvider<ApplicationUser>
{
Subject = "Security Code",
BodyFormat = "Your security code is {0}"
});
manager.EmailService = new EmailService();
manager.SmsService = new SmsService();
var dataProtectionProvider = options.DataProtectionProvider;
if (dataProtectionProvider != null)
{
manager.UserTokenProvider =
new DataProtectorTokenProvider<ApplicationUser>(dataProtectionProvider.Create("ASP.NET Identity"));
}
return manager;
}
}
であるここに私のSQLパスワード調理人コードがあります。
public class SqlPasswordHasher : PasswordHasher
{
public override string HashPassword(string password)
{
return base.HashPassword(password);
}
public override PasswordVerificationResult VerifyHashedPassword(string hashedPassword, string providedPassword)
{
string[] passwordProperties = hashedPassword.Split('|');
if (passwordProperties.Length != 3)
{
return base.VerifyHashedPassword(hashedPassword, providedPassword);
}
else
{
string passwordHash = passwordProperties[0];
int passwordformat = 1;
string salt = passwordProperties[2];
if (String.Equals(EncryptPassword(providedPassword, passwordformat, salt), passwordHash, StringComparison.CurrentCultureIgnoreCase))
{
return PasswordVerificationResult.SuccessRehashNeeded;
}
else
{
return PasswordVerificationResult.Failed;
}
}
}
//This is copied from the existing SQL providers and is provided only for back-compat.
private string EncryptPassword(string pass, int passwordFormat, string salt)
{
if (passwordFormat == 0) // MembershipPasswordFormat.Clear
return pass;
byte[] bIn = Encoding.Unicode.GetBytes(pass);
byte[] bSalt = Convert.FromBase64String(salt);
byte[] bRet = null;
if (passwordFormat == 1)
{ // MembershipPasswordFormat.Hashed
HashAlgorithm hm = HashAlgorithm.Create("SHA1");
if (hm is KeyedHashAlgorithm)
{
KeyedHashAlgorithm kha = (KeyedHashAlgorithm)hm;
if (kha.Key.Length == bSalt.Length)
{
kha.Key = bSalt;
}
else if (kha.Key.Length < bSalt.Length)
{
byte[] bKey = new byte[kha.Key.Length];
Buffer.BlockCopy(bSalt, 0, bKey, 0, bKey.Length);
kha.Key = bKey;
}
else
{
byte[] bKey = new byte[kha.Key.Length];
for (int iter = 0; iter < bKey.Length;)
{
int len = Math.Min(bSalt.Length, bKey.Length - iter);
Buffer.BlockCopy(bSalt, 0, bKey, iter, len);
iter += len;
}
kha.Key = bKey;
}
bRet = kha.ComputeHash(bIn);
}
else
{
byte[] bAll = new byte[bSalt.Length + bIn.Length];
Buffer.BlockCopy(bSalt, 0, bAll, 0, bSalt.Length);
Buffer.BlockCopy(bIn, 0, bAll, bSalt.Length, bIn.Length);
bRet = hm.ComputeHash(bAll);
}
}
return Convert.ToBase64String(bRet);
}
}
ここでログインの方法は、あなたの助けに感謝アカウントコントローラに
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Login(LoginViewModel model, string returnUrl)
{
if (!ModelState.IsValid)
{
return View(model);
}
// This doesn't count login failures towards account lockout
// To enable password failures to trigger account lockout, change to shouldLockout: true
var result = await SignInManager.PasswordSignInAsync(model.Email, model.Password, model.RememberMe, shouldLockout: false);
switch (result)
{
case SignInStatus.Success:
return RedirectToLocal(returnUrl);
case SignInStatus.LockedOut:
return View("Lockout");
case SignInStatus.RequiresVerification:
return RedirectToAction("SendCode", new { ReturnUrl = returnUrl, RememberMe = model.RememberMe });
case SignInStatus.Failure:
default:
ModelState.AddModelError("", "Invalid login attempt.");
return View(model);
}
}
です！
