Android :: Encrypt Outgoing Data? (any Mobile Platform)

Sep 13, 2010

Would it be possible for me to build an application that enables people to encrypt call coming to me with my public key and then for me to decrypt the call data at my end using my own private key. This way I basically have a more secure communication channel which I am assuming because RSA is hard to crack would be difficult to monitor.I am asking this question from a research point of view and have absolutely not considered the factor as to how computationally feasible would such an application be. I would just like to know if there is a way for me to intercept my outgoing data using any built functions.

Android :: Possible To Encrypt Sdcard And Its Contents?

Jul 13, 2010

Security is top priority for me, i realise there are apps out there that can remote wipe lock etc, but if the thief is quick enough to take out the sdcard and put it in another phone the sdcards contents can still be accessed can't it?
So i would like to know if there is anyway to encrypt or protect the sdcard and the contents within it?

General :: LG G2 - Encrypt Android Phone Without Lock Screen?

Feb 28, 2014

I just encrypted my LG G2 and chose I believe a 17 character random password which includes punctuation. It's hard enough to remember and I only wish to enter it when I power on the phone. However it seems I have to enter it every time the phone locks itself. I don't want that, it's a heck of inconvenience. I just want swipe to unlock, not no pin or no pattern and only want to enter the big as password when the phone turns on. I am rooted and on the latest AT&T firmware.

General :: Can't Encrypt SD Card After JB OTA

Dec 20, 2012

My work email requires the phone and external storage to be encrypted to use the Microsoft Exchange server for email.

Email worked fine while on ICS and rooted. After upgrading to JB 4.1.1 (kept root with vodoo root keeper ) the email stopped with a notice I needed to change my security settings. There was nothing I could change.

Deleted the account and when I try to set it up new- I get a message that I can't continue as the IT policy requires external encryption.

Under security> encrypt SD card>Setup data encryption Memory card (along the top) and apply (along the bottom) are grayed out.

I erased the SD card and that did not work.Tried to continue setup without an SD card- no go.

General :: How To Encrypt Folders - Galaxy Note 2

Jan 18, 2013

I'm looking for an app that will allow me to encrypt folders (preferably without having to go through a third-party file manager) on my Galaxy Note 2 and Nexus 7, while possibly being able to also decrypt and view the folder/files on a Windows or Mac machine.

BoxCryptor is one that I've looked into but I'm not sure if it will allow me to encrypt folders within folders.

A little bit of background for what I need this for... I'm a medical health professional and there are times when I have sensitive data about some of my patients that I need to access via my phone/tablet/home/work computer. I don't necessarily need the folder of patient data to sync across all devices but if that could be done (say via DropBox or WebDAV, encrypted), that would be a bonus.

There are some apps on Google Play that seem like they might work:

Encryption Manager
Safe+
DroidCrypt

General :: Galaxy S4 Shuts Down When Attempting To Encrypt

May 11, 2014

I have a Sprint Samsung Galaxy S4 (SPH-L720). My device is currently stock rooted running Android 4.4.2. I recently just did a factory reset and need to encrypt my device. I have my screen lock password setup and when I select to encrypt the device it shows the screen with the android gear icon for a second then shuts off. About a minute later it will turn on again on its own and boot right up to the regular lock screen. It will not encrypt and gives no error message.

The only references I have found on a Google search about encryption not working was referring to an error message saying the encryption failed and asking the user to factory reset.

Jelly Bean :: No Option To Encrypt SD Card Galaxy S3 I747

Nov 25, 2013

From everything I've read I should be able to encrypt my sd card on my i747 but only option I have is to encrypt phone which I've done. Should I be able to encrypt my sd card on this? I have my camera set to save my photos etc on my sd card and would really like it encrypted. I've tried a few of the photo hide programs and they all move the photos to the internal sd card if you hide them from external sd card. If there was an app that would keep them on they drive they are located on I would worry about the sd card encryption as much.

Android :: Encrypt And Decrypt .apk Files / Re-"make" It Again Using WinZip?

Jun 7, 2010

I was wondering how to break apart .apk files in Windows to see all of it's components, edit some of the components, and put the file back together.

I have been able to open up the file to see the components using WinZip but I am unsure of how to re-"make" the .apk file again using WinZip. Is there a special option within winzip or can you just change the extension from .zip to .apk? Not sure if this matters, but the .apk files are being used within Eclipse in an emulator as of now.

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

HTC Droid Eris :: Always Enable Mobile Data Function Causes Data Leakage?

Aug 21, 2010

Can anyone help explain what this does? I did a small search around the internet, and it came up with just about nothing.My first question is: I turned mobile data off, and yet, during the night, I was charged for data, so something leaked.Personally, I thought if this was because of this particular function. But maybe it was something else.So, I turned it off, but around the forums for other androids people seem to think that syncing doesn't work as well with this disabled.Does anybody know what might have happened? And could this function have been the thing that caused the leak.The leak, was actually for only 50 KB or so, but because I'm on Page Plus, it caused me to go under the required balance to refill of $29.95 and caused my plan to lapse. It's important for me for this not to happen again. Can anyone give any tips?

Android :: Fetching Data - Responsebody - HttpClient In An AsyncTask And Returning Data

Mar 16, 2010

How I'm able to do what I've written in the topic. I've looked through many tutorials on AsyncTask but I can't get it to work. I have a little form (EditText) that will take what the user inputs there and make it to a url query for the application to lookup and then display the results.

What I think would seem to work is something like this: In my main activity i have a string called responseBody. Then the user clicks on the search button it will go to my search function and from there call the GrabUrl method with the url which will start the asyncdata and when that process is finished the onPostExecute method will use the function activity.this.setResponseBody(content).

This is what my code looks like simpliefied with the most important parts (I think).

Android :: Loading Google Maps Data Into Searchable Data Structure

Mar 2, 2010

For my CS bachelors I am doing a Senior project using android and google maps.My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?Any pointers would be awesome.I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.
