What is the secure way to store passwords on android device?
I found same topic in "Android Developers Group". Steve918 kindly shared a sample code for it but I can not download it anymore. http://steven.bitsetters.com/articles/2007/11/20/android-password-safe/

I am working on an android application, and I need to use encryption for one aspect of it. I am really indifferent to which algorithm I use (AES, DES, RSA, etc...). I am aware that Java has a crypto package, but I am not at all familiar with. Can someone post an example on how to do an encrypt/decrypt function?

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.
Does anyone know how to decrypt a stored google password on an HTC Hero?
My bro forgot his google password. The secondary email is completely defunct. The security question is completely incomprehensible. He even filled out the form to convince google that he is who he says he is... no dice.
The ONLY place the password is stored is his HTC Hero, as a saved gmail password.
My question is... is there a way to export, decrypt, or recover his gmail password on his Hero?
So I loaded Wave secure beta to my Hero a couple weeks ago. I had occasion to travel to the west coast since and the phone locked as expected and unlocked when I entered my PIN. However, I wanted to test the remote locking feature and when I enter my login and password at the Wave secure web page it telss me I've entered incorrect info. I've verified the info multiple times but still can not login. I sent a msg to TenCube but haven't received a reply. Anyone else have this problem or know what the problem might be?

Would it make installing malware or exploiting a security flaw any more difficult? Assume the device in question is not rooted, if that makes any difference.

The lightness method averages the most prominent and least prominent colors:
(max(R, G, B) + min(R, G, B)) / 2.
The average method simply averages the values: (R + G + B) / 3.
The formula for luminosity is 0.21 R + 0.71 G + 0.07 B.
But i get very weird results ! I know there are other ways to achieve this but is it possible to do this way ?
here is the code...
I have had this same problem happen twice to me on 2 different phones on 2 different Verizon accounts!
The password screen locks and when it asks for the user name and password it states invalid user name / password!
Is this a known problem since when I called and talked to both Verizon and HTC the only thing they could tell me was to do a hard reset and they weren't aware of this problem?

Many of my users have requested a password protection for various data elements in my database. Unfortunately, one of my existing features is backing up the database to a public location (SD Card) for data redundancy, so my database isn't secure.
So my question is two-fold.
How can I encrypt or secure a database on android?
How can I store user created passwords on the device in a secure, inaccessible way.
I purchased an Acer Iconia A200. It took the system upgrade to Ice Cream Sandwich without any problems. After upgrading, I chose to apply the "Encrypt Tablet" feature -- and now I regret that choice. The tablet won't take any more system updates, and apparently it can't ever successfully follow through on a factory reset.
Any way to decrypt an encrypted Ice Cream Sandwich tablet -- or at least if there's a way to factory reset it successfully?
I need to develop an application that will check whether the phone is in roaming. If it's in roaming then the application should block internet for all applications except several from white list. In non-roaming mode it should allow all requests. There should be no way for user to kill or suspend the application or turn internet on.
I'm not familiar with android much so I really don't know whether it possible to implement without modification of OS. Is there any way to do this?
I can build a daemon with my algorithm code and main function.I put all files in one folder under /development and make This executable file works successfully
Now I want to separate my algorithm code and main function code. I hope to build a binary library with my algorithm code and main function will link this binary library to use.
Where to put my algorithm code to create binary library and how to link this binary library in main function code?
I encrypted my Samsung Galaxy Nexus several months ago and now I want to decrypt the drive and wipe the information. Nothing I have tried has worked so far.
The option to perform a factory reset through the OS has not worked. I make the selection, enter in my passphrase, the phone reboots into the green robot screen (like it was updating) then when it boots back up it asks me to enter in the encryption passphrase again and I do then it takes me to my un-wiped phone.
I have also attempted to reset it with the ClockworkMod Recovery and it will not work either. Giving an "Error mounting data!" message and similar message for the rest
I have my Nexus unlocked and rooted but it is running stock other than those two.
On my droid, i need to access a https website that asks for login credentials. when I attempt to use this site, I get a certificate error(normal for our site) then I should get a username and password prompt. Instead, I get a server communication error. I can use this site using a windows phone, as well as any computer browser, but cannot get the user/password prompt from the browser in android. has any one else had a problem like this? the site address is https://corp.mt.net/urms/urms.pl.

View 2 Replies View RelatedSecurity 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?
Is there a way to encrypt a file in Android 4.1?In Linix vim there is an option (vim -x) to do this, but it does not seem to be present in VimTouch.I'd like if possible to share an encrypted file between PC and phone.
View 1 Replies View RelatedI have been rooted since shortly after 2.2 dropped and it broke the SiriusXM app. I love having the ability to do so much with the phone . My question is kind of specific to an application and general to the nature of a rooted device. I have been playing World of Warcraft for 5 years now and with the always present threat of being hacked and all of my in-game items, characters and account being stolen I added the mobile authenticator app as soon as it was available for Android devices. For those who don't know what this is, it is an app which you add to your in game account and will generate a key which you put in upon login that adds an extra layer of security to your account.

I have a couple of videos, that I would like to strip the audio from, and was planning to use FLAC, and/or similar lossless codec; but before I do this, what codecs can Andriod decrypt? According to Android Central, it can decode FLAC, but only in Android 4.0 and higher, and I'm currently on Android 2.3.4 on a HTC Amaze 4G...
Is there any software I could get, in order for it to decode/decrypt FLAC correctly?
I don't mind using any other lossless audio codec, as long as Android 2.3.4 supports it...
