step 1. Install sympleCrypto from nuget then proceed as pblic void Register(User user) { YourDbContext db = new YourDbContext(); User User = new User(); User.UserName = user.UserName; var crypto = new SimpleCrypto.PBKDF2(); var EncryptedPassword = crypto.Compute(user.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(); // do save with Ado.Net } /* 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; }
