In Zeile 4 wird daher ein char -Array definiert, das die von CommonCrypto erzeugte Zeichenkette, also den Hashwert des Passworts, aufnimmt. Zeile 5 ist dann der eigentliche Aufruf der Hashfunktion:. Es nutzt einem Angreifer ohnehin nichts, diesen Wert zu kennen. Dazu ist die Keychain von iOS der vorgesehene und richtige Ort. Verwaltung von Benutzerdaten.

Die Authentisierung, die wir soeben in das Fototagebuch implementiert haben, zeigt die sicherheitstechnischen Minimalanforderungen an einen Authentisierungsmechanismus. In ihr sind keine Funktionen enthalten, die dem Benutzer die Verwaltung seiner Zugangsdaten erlauben. Mit den in diesem Kapitel vorgestellten Techniken sind Sie aber in der Lage, solche Verwaltungsfunktionen selbst zu implementieren. Die Bedeutung des Benutzercodes in iOS. Daher ist es dringend angeraten, immer einen Benutzercode zu verwenden.

Apple bringt iOS 13 & iPadOS - iTunes ist tot

Die Keychain kennt vier Arten von Informationen:. Die Konstanten haben die folgende Bedeutung:. Der Eintrag, dass ein Passwort gesetzt ist, wandert aber sehr wohl mit. Benutzerfreundlichkeit sieht anders aus. Und sichere Software, die niemand benutzt, hilft niemandem. Die Methode zum Speichern des Benutzerpasswortes bzw. Das erste dient zum Auffinden eines eventuell bereits vorhandenen Eintrags searchDict , Zeile 2. Tabelle 7. SecItemUpdate erwartet als Parameter zwei Dictionarys.

Damit sollten Sie jetzt alles beisammen haben, um das Fototagebuch mit einer Authentisierungsfunktion zu versehen. Implementieren Sie alle Klassen und Methoden wie oben beschrieben, und denken Sie an die Importanweisungen in allen Headerdateien. Sie haben in diesem Kapitel bereits mehrfach den Begriff Jailbreak gelesen. Unter einem Jailbreak versteht man das Modifizieren des Betriebssystem-Kernels, so dass dieser das Starten unsignierten Codes erlaubt und das Sandboxing deaktiviert. Entsprechende Beispiele sind in der Vergangenheit bereits durch die Presse gegangen.

Jailbreak-Erkennung und Cracking von Apps. Trennen Sie daher Jailbreak-Erkennung und Lizenzierung voneinander. Ein Jailbreak ist ein Sicherheits- und kein Lizenzproblem. Dagegen hilft dann auch kein Cracken der App. Beim Wald-Feld-und-Wiesen-Jailbreak, den Benutzer installieren, um den Funktionsumfang ihres iDevice zu erweitern, sind immer bestimmte Verzeichnisse und Dateien vorhanden, die den Jailbreak als solchen identifizieren. Die in Listing 7. Jailbreaks haben die Root-Partition statt readonly stets als writable gemountet.

Seit iOS 7 ist Apps dies erlaubt. Die Implementierung der Methode in SecUtils. Es ist daher etwas naiv, ein kompromittiertes System zu befragen, ob es kompromittiert ist. Was die Zukunft bringt, bleibt abzuwarten. Mit iOS 5 sind zwei weitere Schutzklassen hinzugekommen, die eine feinere Granulierung der Zugriffsrechte erlauben:. You don't need much horsepower to run the SDK and you can always sell it on later if you decide to stop development or buy a better Mac. Apple does not allow these Client OSes to be virtualized.

With Mac OS X Xamarin is now my top vote. Purchased by Microsoft and built directly into Visual Studio now and being able to use C and with all the updates and features they are adding, you can do everything on Windows, even compile, build and initiate deployment. You only need a Mac Mini to act as the deployment server, but you never need to write any code on it. For games, Unity 3D is my top choice.

The editor is free up to K annual revenue perfect for indie. Unity supports iOS, Android and most other platforms. PhoneGap also works, but I have found it isn't quite as nice for gaming, but it's pretty decent for regular GUI applications. Again, you'll need a Mac to sign and test your application and be in compliance with Apple's terms of use.

Flutter is a free cross platform mobile app development framework from Google. If you have a jailbroken iPhone, you can install the iphone-gcc toolchain onto the iPhone through Cydia and that way you can just compilie the apps on the iPhone. Apps that are developed this way can still be submitted to the App Store. And although Mr Valdez said it is a grey area which it is , jailbreaking is incredibly easy and pretty much risk free.

Yes, it voids your warrenty but you can just do a restore and they will never know. Most of "so called Windows solutions for iOS development without Mac" require Mac at the end just to sign and send to app store. I checked a few, not all though who has the time? At the end it's just too much trouble to learn "their super special easy way to program iOS without Objective-C", they have lots of bugs.

Really the goal they are setting is unachievable in my view. Also a lot of time they make you use Objective-C equivalent statements simply in another language. They kind of look the same but there are always subtle differences that you have to learn on top of obj-c. Which also makes even less sense, because now instead of learning less you have to learn more.

So where is the gain? Also they cost a lot, because they are very hard to develop. In my honest opinion, if you are a hard-core iOS developer then for sure buy the best Mac and learn objective-c. It's expensive and takes time, but if it's your path, it's worth it. For an occasional use, it's just easier to rent a remote Mac service, like XCodeClub. In my experience the virtual machine solution is unusably slow on a core2 duo laptop with 2G ram.

If you feel like trying it search for the torrent. It's probably not worthwhile. You can find lots of articles on how to do this; here's one on how to install on a Dell Inspirion laptop: hackbook pro tutorial. Of course both of these options are likely counter to some licensing scheme, so proceed at your own risk. You can use WinChain.

This article one of our developers wrote gives a pretty comprehensive walk through on installing OS X Snow Leopard on Windows using iBoot, then installing Vmware with instructions , then getting your iPhone dev environment going Super helpful for me. You can use Tersus free, open source. Pretty neat, it even builds IPA files for your app after a successful compilation.

    But still, it enables you to develop using a well-known IDE.

    Of course, you can write Objective-C code in notepad or other programs and then move it to a Mac to compile. But seriously, it depends on whether you are developing official applications to put in App Store or developing applications for jailbroken iPhone. However, there is an unofficial toolchain to write applications for jailbroken iPhones. You can run it on Linux and Windows using Cygwin.

    Try macincloud. You can then use your PC to access a mac and then develop your apps. You can now more easily accomplish this with the latest Xamarin. If you want it to be legitimate, you have two options, cloud based Mac solutions or cross-platform development tools. You may consider the hackintosh approach or virtual machines if you don't care about legal stuff.

    If you have a decent PC, running a virtual machine would be the easiest way to go. You may never know which hardware will have driver issues on a hackintosh. I've tried all these approaches and they all have pros and cons, but for the second group, I feel kind of guilty. I develop apps to make a living and I wouldn't want to rip off someone else for it.

    If you are making a small project, cloud based Macs may prove useful. Rent it for a short time, develop your project and off you go. Don't bother learning anything new. However, if your project is getting big, cross-platform frameworks seem to be the only alternative. The critical thing is that you need to choose wisely. There are so many hybrid frameworks, but what they do can be summarized in one sentence as "diplaying web pages in an app wrapper" and developers' negative experience with hybrid frameworks also affects native frameworks.

    I tried three of these Titanium, Smartface and Xamarin and they all claim to produce "real native output" and in my opinion their claims are correct. You need to test and see it yoursrlf, it's not easy to describe the native feeling. In a previous comment, it was indicated that it takes some effort to learn these platforms, but once you get to know them, you can develop not just iOS applications but Android applications as well, all with the common code base. And of course, they are much cheaper than a cloud Mac.

    Some of them are even free.

    Licht & Schatten

    You would need a Mac only for store submission. Just note that for the device simuator, Titanium is dependent on a Mac, but Smartface has a simulator app for Windows development and it works better than I expected. On the other hand, Xamarin requires a Mac in your network. Check this Link Dragon Fire sdk. ARC and blocks are supported. Interesting that no one has mentioned the cross-platform wxWidgets option. It's less than an optimal solution, though.
