About Home Network SSL Checker APK
Table Of Contents
Description
The standard Android applications for mail, calendar, contacts etc. can synchronize against SSL-protected servers but have no option to check their certificate. Basically, it is possible to either check if the certificate is issued by one of the standard (before Android 4.0, not user-editable) CAs, or not check them at all. This is not enough to reliably assert the identity of the server, which presents the risk of giving sensitive information (account passwords) to the wrong server. This problem is especially important when the server is on a semi-permament connection and found via dynamic DNS, uses self-signed or private-CA certificates, or when using public WiFi hotspots (which are rather trivial to fake and therefore are a regular MitM-attack vector).This app checks in configurable intervals if a given HTTPS URL is reachable and the server identifies itself with the right certificate. It consists of a home screen widget displaying the status with colored "signal lights":
* green, if the connection is okay
* yellow, when a check is underway
* red, when the server is unreachable
* double red, when the server gives errors or fails certificate checking
* small white, when checking is not needed
When checking and when an error happens, the global synchronization setting is turned off. This way you should be reasonably safe that the synchronization does not try to connect to a server whose identity is not verified, given it is the same server as the one you check.
This is an open source (GPL) app. Source and further documentation is available via my Web site.
Permissions needed:
INTERNET - connect to your server (nowhere else)
ACCESS_NETWORK_STATE - determine your connection (WLAN, mobile...) to find out if checking is needed
READ_SYNC_SETTINGS, WRITE_SYNC_SETTINGS - turn sync off on checking or error
RECEIVE_BOOT_COMPLETED - automatic start (if possible, depending on Android version)
READ_EXTERNAL_STORAGE - read certificates from memory or SD card

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
