有几个这样的加密问题，如果是为了存储密码，那么你可能没问题(虽然我记不清了).但是，如果您加密任何类型的网络流量(即使它只是通过 HTTPS 获取页面)，那么您需要向美国***注册您的应用程序(如果您在美国).在您获得注册时，Apple 可能会允许您在仅限美国的商店中销售您的应用.

There are several of those encryption questions and if it is for storing passwords, then you probably are OK (although I don't remember exactly). If you encrypt any kind of network traffic, however (even if it is just getting a page via HTTPS), then you'll need to register your app with the US government (if you are in the US). While you are obtaining that registration, Apple may let you sell your app in the US-only store.
