App Store Review Guidelines says: "Apps that download code in any way or form will be rejected."
I'd like to make an app using Challenge-Response for authentication. The app has a set of basic algorithms such as SHA-1, SHA-256, MD5, DES, AES and so on. The challenge server makes contains an array of the algorithms' name with random arrangement and a string names A. Client uses the algorithms and the sequence that challenge indicates to manipulate string A, and returns it to the server as the response.
Although all I transfer between server and client is a bunch of strings, but they indeed change the behavior of my app. Should I consider them a form of code? If not, why downloading shell code to execute is forbidden by Apple? I mean, shell code is also a bunch of strings and interpreted by running environment. Where is the essential difference?
Forgive my English :)
What Apple is worried about and wanting to prevent is applications that get through the approval process (disguised as something benign) and later change their fundamental function.
An extreme example would be an application downloading new, malicious executable code after it has been installed on the user's device.
Apple is using broad wording in order to be able to reject any app that in any way tries to be harmful to the user. It would be impossible to specifically describe every technique and specific way this could happen, so Apple keeps the wording loose.
Apps "download code" in some form or another all the time, consider an application that accesses an API that returns JSON formatted responses. Technically that could be considered code, and it can change the apps behavior (which view to show, what options would be available on a certain view, etc). But an app that access an API in this manner would certainly not be rejected.
From what I can gather from your question, it sounds like you don't have to worry about that particular clause in the guidelines.
I want to build simple web based app, where users, for example, could push the spacebar button, and then do something further, like answer a question, and while other users at the same time only sees that this question is not available any more for answer. When user submits answer, everyone see it.
All right, here is an example. I have seen TV shows, where four players have one button, if one or two of them know answer, they hit a button, and one lamp turns on and the first is allowed to answer, while other keeps their mouths shut. I want to build the same idea, but in the web.
But problem is that, I don't know where to start, what keywords I should search for help on google and so on. I see, that it might work on HTML5, maybe JavaScript and so on.
I have idea using Ajax, but request it every second to get latest actions made seems rubbish. Also I found one service called Pusher, but it has limited users in one time, which doesn't fit my needs.
I need just ideas. Thanks.
Before you read the rest, a disclaimer: I work for Realtime.co but I do believe I can help here so I'm not trying to "pitch a sale".
You can check out Realtime (www.realtime.co). It's basically a set of tools for developers to use real time technologies on their projects. It uses websockets but does fallback to whatever the user's browser supports (such as long polling, for example).
Behind Realtime you have a one-to-one/one-to-many/many-to-many messaging system that will transport your messages to and from your users.
There's also a plus which is the fact that the Realtime framework is actually cross-platform. This means that you can even have your web users communicate with iPhone users, Android, users, Windows Phone, desktop applications, server applications, etc..
You can learn about the JavaScript API here: http://docs.xrtml.org/getting_started/hello_message.html#javascript.
You only need to register at Realtime.co as a developer and start using the free license.
I really hope that helps.
Okey, I think I will go with node.js.
Writing all this previous post, made me think in right way :)
have developed some quite good basic Facebook App development experience, can hook apps up to databases, have different info installed and displayed on different tabs no probs. However, everything Ive been doing so far to date revolves around me manually going into my developer account and setting up each apps settings individually, one at a time. Am curious to figure out how people like tabsite have created an interface that captures users input data and displays on tabs (that part i understand) but also it registers new apps each time on the fly (this part am curious about how its done), allowing them to add individual app logos, tabnames etc without the user ever having to go anywhere near the developer set up. And how are tabsite getting data back from the developer such as app_id or app_secret??
Any insight much appreciated.
Regards Tony
As I recall there isn't a way to register an app using the API. They probably just use only one app, and then check the signed_request variable to get the Facebook Page ID, which they then link together with the data in the database.
https://developers.facebook.com/docs/authentication/signed_request/
You're allowed 2 tabs on a single page on their free account. But you can only add an app once. This implies they've either created a number of apps that are exactly the same(11 would be my guess as that's how many tabs their best plan offers) There used to be a way to do it using one of the old SDKS but as far as I was aware it was deprecated and is no longer available.
The fact that you say you can customise the tab image though, does imply that they're creating new apps, as far as I am aware you can only customise the image within the app settings in the developer app.
After a bit of investigation, this post may have more info

I want to know if there is a possibility to add a team member in iPhone Developer Portal that will have permissions (see / modify / update) ONLY to one application.
The reason - there is a big company (that has many applications in the App Store) that uploaded one of my applications and I have hard time to send an update to the application (can't access the guy that is responsible for all the iPhone applications).
I want to ask them to add me as a team member, but they might agree only if I won't be able to see/touch any other application except the one that I have developed...
Thank you.
I don't believe this is possible; there are no per-app permissions.
The available "roles" are explained here:
http://developer.apple.com/programs/roles/index.php
It seems a bit odd if they trust you to write an application that they've published under their corporate identity, but don't trust that you'll only change what you're meant to. Either way is seems the only solution to your problem is likely to be a non-technical one; you need to find a way to get to that guy, whether it's appealing to his better nature, or finding a path to someone more senior who can lean on him.
I'm uploading a binary for the first time. iTunes Connect has asked me:
Export laws require that products containing encryption be properly authorized for export.
Failure to comply could result in severe penalties.
For further information, click here.
Does your product contain encryption?
I use https://, but only via NSURLConnection and UIWebView.
My reading of this is that my app doesn't "contain encryption," but I'm wondering if this is spelled out anywhere. "Severe penalties" doesn't sound pleasant at all, so "I think that's right" is a bit sketchy... an authoritative answer would be better.
Thanks.
UPDATE: Using HTTPS is now exempt from the ERN as of late September, 2016
https://stackoverflow.com/a/40919650/4976373
Unfortunately, I believe that your app "contains encryption" in terms of US BIS even if you just use HTTPS (if your app is not an exception included in question 2).
Quote from FAQ on iTunes Connect:
"How do I know if I can follow the Exporter Registration and Reporting (ERN) process?
If your app uses, accesses, implements or incorporates industry standard encryption algorithms for purposes other than those listed as exemptions under question 2, you need to submit for an ERN authorization. Examples of standard encryption are: AES, SSL, https. This authorization requires that you submit an annual report to two U.S. Government agencies with information about your app every January.
"
"2nd Question: Does your product qualify for any exemptions provided under category 5 part 2?
There are several exemptions available in US export regulations under Category 5 Part 2 (Information Security & Encryption regulations) for applications and software that use, access, implement or incorporate encryption.
All liabilities associated with misinterpretation of the export regulations or claiming exemption inaccurately are borne by owners and developers of the apps.
You can answer “YES” to the question if you meet any of the following criteria:
(i) if you determine that your app is not classified under Category 5, Part 2 of the EAR based on the guidance provided by BIS at encryption question. The Statement of Understanding for medical equipment in Supplement No. 3 to Part 774 of the EAR can be accessed at Electronic Code of Federal Regulations site. Please visit the Question #15 in the FAQ section of the encryption page for sample items BIS has listed that can claim Note 4 exemptions.
(ii) your app uses, accesses, implements or incorporates encryption for authentication only
(iii) your app uses, accesses, implements or incorporates encryption with key lengths not exceeding 56 bits symmetric, 512 bits asymmetric and/or 112 bit elliptic curve
(iv) your app is a mass market product with key lengths not exceeding 64 bits symmetric, or if no symmetric algorithms, not exceeding 768 bits asymmetric and/or 128 bits elliptic curve.
Please review Note 3 in Category 5 Part 2 to understand the criteria for mass market definition.
(v) your app is specially designed and limited for banking use or ‘money transactions.’ The term ‘money transactions’ includes the collection and settlement of fares or credit functions.
(vi) the source code of your app is “publicly available”, your app distributed at free of cost to general public, and you have met the notification requirements provided under 740.13.(e).
Please visit encryption web page in case you need further help in determining if your app qualifies for any exemptions.
If you believe that your app qualifies for an exemption, please answer “YES” to the question."
It's not hard to get approval for your app the proper way. SSL (HTTPS/TLS) is still encryption and unless you are using it just for authentication, then you should get the proper approval. I just received approval, and my app is in the store now for something that uses SSL to encrypt data traffic (not just authentication).
Here is a blog entry I made so that others can do this the proper way.
apple itunes export restrictions
Short answer: Yes, but you don't have to do anything
I was searching the web for this for some hours. Actually it is pretty easy and you can verify this in itunes connect:
1. All you have to do
If your app uses only HTTPS or uses encryption only for authentication, tokens, etc., there is nothing you have to do, just include
<key>ITSAppUsesNonExemptEncryption</key><false/>
in your Info.plist and you are done.
2. Verification
You can verify this in itunes connect.
select your app
chose features
chose encryption
click "+"
follow the dialog
for https or authentication the answer is yes and yes
In any case you should of course read yourself carefully through the dialog.
A very helpful article can be found here:
https://www.cocoanetics.com/2017/02/itunes-connect-encryption-info/
I asked Apple the very same question and got the answer (from a Sr. Export Compliance Specialist), that "sending information over https is forcing the data to go through a secure channel from SSL, therefore it falls under the U.S. Government requirement for a CCATS review and approval." Note that it doesn't matter that Apple has already done this for their SSL implementation, but for the government, if you USE encryption that is the same (to them) as you would've coded it yourself. I also updated our blog (http://blog.theanimail.com) since Tim linked to it with updates and details on the process. Hope that helps.
All of this can be very confusing for an app developer that's simply using TLS to connect to their own web servers. Because ATS (App Transport Security) is becoming more important and we are encouraged to convert everything to https - I think more developers are going to encounter this issue.
My app simply exchanges data between our server and the user using the https protocol. Seeing the words "USES ENCRYPTION" in the disclaimers is a bit scary so I gave the US government office a call at their office and spoke to a representative of the Bureau of Industry and Security (BIS) http://www.bis.doc.gov/index.php/about-bis/contact-bis.
The representative asked me about my app and since it passed the "primary function test" in that it had nothing to do with security/communications and simply uses https as a channel for connecting my customer data to our servers - it fell in the EAR99 category which means it's exempt from getting government permission (see https://www.bis.doc.gov/index.php/licensing/commerce-control-list-classification/export-control-classification-number-eccn)
I hope this helps other app developers.
If you use the Security framework or CommonCrypto libraries provided by Apple you do include crypto in your App and you have to answer yes - so simply because libraries were provided by Apple does not take you off the hook.
With regards to the original question, recent posts in the Apple Development Forums lead me to believe that you need to answer yes even if all you use is SSL.
As of September 20th, 2016, registering is no longer required for apps that use https (or perhaps other forms of encryption): https://web.archive.org/web/20170312060607/https://www.bis.doc.gov/index.php/informationsecurity2016-updates
In fact, on SNAP-R you can no longer choose 'encryption registration':
Specifically, they note:
Encryption Registrations no longer required – some of the information
from the registration now goes into the Supp. No. 8 to Part 742
report.
This means you may need to send an annual report to BIS, but you don't need to register and you can note when submitting your app that it is exempt.
Yes, according to iTunes Connect Export Compliance Information screens, if you use built-in iOS or MacOS encryption (keychain, https), you are using encryption for purposes of US Government Export regulations. Whether you qualify for an export compliance exemption depends on what your app does and how it uses this encryption. Attached images show the iTunes Connect Export Compliance Screens to help you determine your export reporting obligations. In particular, it states:
If you are making use of ATS or making a call to HTTPS please note that you are required to submit a year-end self classification report to the US government. Learn more
#hisnameisjimmy is correct: You will notice (at least as of today, Dec 1st 2016) when you go to submit your app for review and reach the Export Compliance walkthrough, you'll notice the menu now states that HTTPS is an exempt version of encryption (if you use it for every call):
I found this FAQ from the US Bureau of Industry and Security very helpful.
encryption
Question 15 (What is Note 4?) is the important point:
...
Examples of items that are excluded from Category 5, Part 2 by Note 4 include, but are not limited to, the following:
Consumer applications. Some examples:
piracy and theft prevention for software or music;
music, movies, tunes/music, digital photos – players, recorders and organizers
games/gaming – devices, runtime software, HDMI and other component interfaces, development tools
LCD TV, Blu-ray / DVD, video on demand (VoD), cinema, digital video recorders (DVRs) / personal video recorders (PVRs) – devices, on-line media guides, commercial content integrity and protection, HDMI and other component interfaces (not videoconferencing);
printers, copiers, scanners, digital cameras, Internet cameras – including parts and sub-assemblies
household utilities and appliances
Simple answers are Yes(App has encryption) and Yes(App uses Exempt encryption).
In my application, I am just opening my company's website in WKWebView but as it uses "https", it will be considered as exempt encryption.
Apple document for more info: https://developer.apple.com/documentation/security/complying_with_encryption_export_regulations?language=objc
Alternatively, you can just add key "ITSAppUsesNonExemptEncryption" and value "NO" in your app's info.plist file. and this way iTunes connect won't ask you that questions anymore.
More info: https://developer.apple.com/documentation/bundleresources/information_property_list/itsappusesnonexemptencryption?language=objc
You can follow these 3 simple steps to verify if your application is exempt or not: https://help.apple.com/app-store-connect/#/dev63c95e436
You may need to submit this annual-self-classification to US gov. For more info: https://www.bis.doc.gov/index.php/policy-guidance/encryption/4-reports-and-reviews/a-annual-self-classification
LOOKS LIKE HTTPS COUNTS

https://www.bis.doc.gov/index.php/policy-guidance/encryption/4-reports-and-reviews/a-annual-self-classification
Just adding my personal interpretation of a very special case:
In my app the user has the option to go to a website themselves or let my app open Safari and Safari will call an HTTPS website. Could be any - own website, article etc etc. I interpret Safari making the actual HTTPS call, not my app and therefore answer the first question with No (or set the flag in the info.plist) and have no requirement to annually report.
If you're not explicitly using an encryption library, or rolling your own encryption code, then I think the answer is "no"
