MVC Login Apply to WinForms

please explain what do you mean by register on mvc and winforms.

anyway if you want to use same logic in both application and on same database then create a class library and

give reference of dll to both winform and mvc , so you write logic at one place and use it anywhere.

install simpleCrypto from nuget and then in your class library under UserBusiness Class

public class UserBusiness
{
public string Name {get;set;}
public string password {get;set;}
public string salt{get;set;}
Public void Save(string username, string Password)
{
YourDbContext db = new YourDbContext();
User User = new User();
User.UserName = userName;
var crypto = new SimpleCrypto.PBKDF2();
var EncryptedPassword = crypto.Compute(Password); // password includes salt , you will need this salt to compare psd in future.
var Salt = crypto.Salt; // this is the salt that has been used behind the scene.
User.Password = EncryptPassword;
User.Salt = Salt;
db.Users.Add(User);
db.SaveChanges();
}
/* if you want to check the same password is being entered by user as in database to confirm password/recovery*/
public static bool IsValidPassword(string EnteredPassword)
{
var salt= /* fetch salt from database*/;
var PasswordInDb= /* fetch Password from database*/;
var crypto = new SimpleCrypto.PBKDF2();
string originalPassword = crypto.Compute(PasswordInDb,Salt);
return crypto.Compare(originalPassword,EnteredPassword); // it will return true/false;
}
}

Hi what I want to happen is if I register online using MVC, then I will sync to my local database. Even if without internet I can still login to my local with the same password that I registered online..
