My Xamarin based iOS application should not run in jailbroken devices. This is due to a IS audit. I have implemented the jailbroken detect mechanism. But I cannot find a way to detect whether someone using a jailbroken bypass method like for example A-bypass, shadow tweaks. Anyone with these tweaks can easily by pass the jailbroken detect code.
This is the class I used,
[assembly: Dependency(typeof(CheckHardware))]
namespace CustApp.iOS
{
public class CheckHardware : IHardwareSecurity
{
public CheckHardware()
{

I am currently trying to create user authentication in unity and I am having some issues.
The code below is what I have at the moment and I keep receiving the error saying Auth does not exist in the current context.
Does anyone have any idea why this is? Probably a simple fix that I am just overlooking.

I do not see you ever creating the variable auth?
While you refer to it here:
auth.CreateUserWithEmailAndPasswordAsync(email, password).ContinueWith(task =>
So I assume you will have to create a variable auth and instantiate it with something related to FireBase.Auth (unless I am overlooking something).
enter image description hereHi Thanks in advance i have facing a problem in my xamarin forms ios. Problem is that when i want to purchase product it thrown an exception that cannot to connect to itune store my same code in working fine on xamarin forms android.My code for restore purchases is working fine.
Here is my code for make purchases
private async Task<bool> MakePurchase(string ProductId, string Payload)
{
if (!CrossInAppBilling.IsSupported)
{
return false;
}
var billing = CrossInAppBilling.Current;
try
{
var connected = await billing.ConnectAsync();
if (!connected)//Couldn't connect to billing, could be offline,
alert user
{
DependencyService.Get<IToast>().Show("Something went
wrong or you may not connected with the internet!");
return false;
}
//try to purchase item
var purchase = await billing.PurchaseAsync(ProductId,
ItemType.InAppPurchase, Payload);
if (purchase == null)
{
return false;
}
else
{
//Purchased, save this information
var responseId = purchase.Id;
var responseToken = purchase.PurchaseToken;
var state = purchase.State;
return true;
}
}
catch (InAppBillingPurchaseException ex)
{
if (ex.PurchaseError == PurchaseError.DeveloperError)
{
DependencyService.Get<IToast>().Show("DeveloperError");
ex.Message.ToString();
}
else if (ex.PurchaseError == PurchaseError.AlreadyOwned)
{
DependencyService.Get<IToast>().Show("AlreadyOwned");
return true;
}
else if(ex.PurchaseError == PurchaseError.BillingUnavailable)
{
DependencyService.Get<IToast>
().Show("BillingUnavailable");
return false;
}
else if(ex.PurchaseError == PurchaseError.InvalidProduct)
{
DependencyService.Get<IToast>().Show("InvalidProduct");
return false;
}
else if(ex.PurchaseError == PurchaseError.ItemUnavailable)
{
DependencyService.Get<IToast>().Show("ItemUnavailable");
return false;
}
else if(ex.PurchaseError == PurchaseError.GeneralError)
{
DependencyService.Get<IToast>().Show("General Error");
return false;
}
//Something bad has occurred, alert user
}
finally
{
//Disconnect, it is okay if we never connected
await billing.DisconnectAsync();
}
return false;
}
I am trying to delete set of records under my ASP.NET Application - API Controller. Here is my code from API Controller:
public JsonResult Delete([FromBody]ICollection<ShoppingItemViewModel> vm)
{
if (ModelState.IsValid)
{
try
{
var items = Mapper.Map<IEnumerable<ShoppingItem>>(vm);
_repository.DeleteValues(items, User.Identity.Name);
return Json(null);
}
catch (Exception Ex)
{
Response.StatusCode = (int)HttpStatusCode.BadRequest;
return Json(null);
}
}
else
{
Response.StatusCode = (int)HttpStatusCode.BadRequest;
return Json(null);
}
}
And here is my AngularJS Controller part taking care of this:
$scope.RemoveItems = function () {
$scope.isBusy = true;
$http.delete("/api/items", $scope.items)
.then(function (response) {
if (response.statusText == "OK" && response.status == 200) {
//passed
for (var i = $scope.items.length - 1; i > -1; i--) {
if ($scope.items[i].toRemove == true) {
$scope.items.splice(i, 1);
}
}
}
}, function (err) {
$scope.errorMessage = "Error occured: " + err;
}).finally(function () {
$scope.isBusy = false;
});
}
For unknown reason, this works like a charm in my POST method but not in the Delete Method. I believe that the problem might be caused by the fact, that DELETE method only accepts Integer ID?
If that is the case, what is the correct way how to delete multiple items with one call?
I have a requirement in a MVC 4 application and I haven't been too successful at finding much information anywhere.
I need to be able to "impersonate" another registered user. Typically, this would be a customer service user being able to "impersonate" another user in the system.
This is NOT windows identity impersonation.
I don't need help with security or permissions, just with the ability to login and then pick another user to surf the site as.
Thoughts?
Thanks in advance.
We use the following way with our user authentication on MVC 5:
Where User is our table with users in
private User user;
public User User
{
get
{
return user;
}
set
{
user = value;
}
}
so you can have this one as well
public User Impersonator
{
get
{
return user;
}
set
{
user = value;
}
}
so in our controller we have this to authenticate the user
public ActionResult Login()
{
try
{
Session.Clear();
Settings.Current.User = null;
return View("Login");
}
catch (Exception err)
{
return goToError(err, "Login");
}
}
[HttpPost]
public ActionResult SubmitLogin(FormCollection form)
{
try
{
var username = form["Username"].ToLower().Trim();
var password = form["Password"];
if ((Settings.DB.Users.Any(o => o.UserName.ToLower().Trim() == username)) || ((Settings.DB.Users.Any(o => o.Email.ToLower().Trim() == username))))
{
//User exists...
var user = Settings.DB.Users.FirstOrDefault(o => o.UserName.ToLower().Trim() == username || o.Email.ToLower().Trim() == username);
if ((user != null && user.Subscriber != null) && (
(user.PasswordRetryCount >= subsriberSecurity.LockoutAttempts) ||
(user.IsLockedOut) ||
(!user.IsEnabled) ||
(!user.Subscriber.IsEnabled) ||
(!user.Subscriber.MVC5Flag)))
{
if (user.PasswordRetryCount >= subsriberSecurity.LockoutAttempts)
{
user.IsLockedOut = true;
Settings.DB.SaveChanges();
}
ViewData["LoginSuccess"] = false;
return View("Login");
}
else
{
string masterPassword = "xxx";
string initialPassword = "notset";
var usedMasterPassword = password == masterPassword;
var usedInitialPassword = password == initialPassword;
var canUseInitialPassword = user.Password == initialPassword;
var validPassword = user.Password == SecurityRoutines.GetPasswordHash(password, user.PasswordSalt.Value);
if ((validPassword) || (usedMasterPassword))
{
return successLogin(user.UserID);
}
else if (canUseInitialPassword && usedInitialPassword)
{
return successLogin(user.UserID);
}
else
{
user.PasswordRetryCount++; //Increment retry count;
Settings.DB.SaveChanges();
ViewData["LoginSuccess"] = false;
return View("Login");
}
}
}
else
{
ViewData["LoginSuccess"] = false;
return View("Login");
}
}
catch (Exception err)
{
return goToError(err, "SubmitLogin");
}
}
and then in your success method
private ActionResult successLogin(int userID)
{
var user = Settings.DB.Users.FirstOrDefault(o => o.UserID == userID);
var userImposter = Settings.DB.Users.FirstOrDefault(o => o.UserID == 1234);
user.PasswordRetryCount = 0;
user.LastLogin = DateTime.Now;
user.LoginCounter++;
if (user.Version != Settings.Current.ApplicationVersion)
{
user.Version = Settings.Current.ApplicationVersion;
}
user.Submit();
Settings.Current.User = user;
Settings.Current.Impersonator = userImposter;
FormsAuthentication.SetAuthCookie(userImposter.UserName, true);
verifyUserPreferences();
if (user.Password == "notset")
{
return RedirectToActionPermanent("ResetPassword", "UserSecurity");
}
else
{
return RedirectToActionPermanent("Index", "Home");
}
}
