Android :: Best Encryption Library For Mobile Devices?

Jan 18, 2010

I have been using LibTomCrypt to use SHA1 encryption ( for data integrity checking ) on mobile devices (iPhone OS and Android for the moment ). I was wondering if anyone is using anything else, things to consider are Portability ( C preferred but C++ is also an option ), and libraries size ( small == better for my particular needs ).

Android :: T-Mobile G1 Won't Appear In Adb Devices List

Aug 27, 2010

I'm trying to connect to connect to my T-Mobile G1 to test a simple android app I an creating. I cannot get it to show up in the list of connected android devices. Here are the details: - 32-bit Windows XP - I have enabled USB Debugging on my device - I am not prompted with the New Hardware Wizard when I plug my device in, it is merely seen as a new removable drive. It does not appear under any other categories in Device Manager, nor is there a new "Unknown Device" entry anywhere to be found - I have tried "Update Driver" and select the driver that Google provides for their official developer devices, but it says "this driver does not match your device" or something to that effect. Probably because it is expected a device type other than "Disk Drive" - I have tried uninstalling the device under "Disk Drives" and plugging it in again but it always gets reinstalled automatically as a "Disk Drive" - I have tried uninstalling the device, manually installing the Google driver from the INF file and plugging in the device and it is still only recognized as a "Disk Drive" - Most importantly, I get a blank device list when I run "adb devices" from the Android SDK tools directory before and after each step I tried After hours of scouring the web I get the distinct impression that a new device category should be popping up in Device Manager if the driver is installed correctly, but I have not been able to get the device to come up as anything other than a new "Disk Drive"

Android :: Why Would Hulu Block Mobile Devices?

Aug 4, 2010

I don't see the logic behind this. The more people who watch hulu means more people who are looking at ads. And the more people who look at ads, the more money hulu makes. The only logic I could see behind this is that a Hulu Plus app is coming to the Android market, but I haven't heard anything about that.What's your take on this?

Android :: Self-contained Test Library Project Cannot Find Library Classes

Aug 17, 2010

According to this SDK guide, unit-testing a Library project can be achieved by creating a standard application project, reference the Library project and then instrument the application for unit testing. However, when I do this and launch the test application I get the message.No tests found with test runner 'JUnit 3".I'm using Eclipse and the Android ADT plugin, all latest versions.the projects compile just fine. The test project also installs fine to the emulator. But in the console I can see that it looks for <library>.apk, which of course doesn't exist since I'm compiling this as a library into the test project.

Android :: Differences Between Jar Library And Library Project

Jul 15, 2010

As I understand, the three ways of distributing my application are via Jar, Android Library and Android Library Project.Jar - cannot contain resources or XML layouts (so this is out for me)Android Library - I don't really know how this works but the Google API uses it..Android Library Project - includes resources but allows the client free rein on the code as it is distributed as source.If I am to create a closed source application that requires drawables and XML files that I want to distribute to other Android programmers, what should I use? And can someone direct me to a tutorial on creating an Android Library?

Android :: SD Card Encryption App For Phone?

Apr 8, 2010

I'm look for an app that will encrypt my SD card. I don't want to worry about losing my phone and the finder having access to the information on my SD card. I know it'll slow the phone down.

'Gallery Private' in the market looks like it may do this. Does anyone have experience with this app? Does it only encrypt pictures and folders?

'B-Folders+sync' looks like it only does contacts and notes. I may need a combination of them both.

Makes me sort of wish there was a BitLocker-esque app available.

Android :: Password Security - Encryption - Decompile

Feb 2, 2010

I am developing an app that uploads files to an FTP server, and the app will have the ftp user name / password in the code. I'm investigating making the FTP user name and password as secure as possible (including an encrypted value for each in a strings.xml and decrypting in the app when it needs to connect to the FTP server).

My concern is this is not actually secure at all, it seems someone could unzip the .apk, decompile it, view the strings.xml and java code that decrypts it - and thereby obtain the ftp login info.

So my question is.. am I approaching this wrong way? Is there a standard method of ensuring passwords that are hard coded into an app can be secure? (note - in this case this is not a password a user of the app would enter, the FTP password is universal to all that install it so it is included in the app).

Android :: Recommended Encryption Combination For Digital Signatures

Jul 3, 2010

I have finally - after days and days of agony - figured out that I need two forms of encryption for my Digital Signatures Project. The first will will be symmetric (AES) and will encrypt the license data and the second will be a asymmetric (RSA) an will encrypt the symmetric key. Can someone give me pointers on the best methods to use for Android.

For the public/private keys I am using: "RSA/ECB/PKCS1Padding"(I head ECB is bad so what should I use?, what about the PKCS1Padding - shoudl I be using PKCS5Padding?)

For the symetric keys I will probably use: "AES/?/?" (What mode and padding should I use?)

The provider: "BC"

RSA Keysize: 1024 (I tried 2048 but it didn't work for some reason)

AES Keysize: ?

Android :: Extend Contacts Application To Provide Encryption

Nov 16, 2009

I want to encrypt individual contacts stored by the Contacts application on Android based on user's preference. So, I am thinking I'll have to hook/extend the Contacts application before the it stores data into the database and decrypt it when the user wants to view it. Also, I am assuming I will have to store the key for encryption in a file.

General :: GS2 I9100 / CM9 - Full Device Encryption Android

Jul 9, 2013

I'm on gs2 I9100 cyanogenmod 9 and can't find a solution to encrypt internal databases like sms, call logs, contacts... ( so in /data).

No problems with documents in container created by luksmanager. But i wonder is it possible to make a sort of preboot script who mount after correct passphrase a luks container who is symlinked in /data ? Because android ics built in encryption installation stop at beginning.

Is there now new method or app to encrypt full or partial phone? Maybe new encryption function or improvement in JB? Pattern/face unlock fixed?
