I recently with though a "lost device scare" but I was able to get it back but it got me thinking into securing my device more I was curious about the Native Encryption option on our settings will I still be able to copy pictures off my SD afterwards? And is it root Friendly meaning can I still use titanium to back up my apps afterwards..

Enabled native encryption on phone and SD card. Phone took a dip in the ocean. Files on the SD card need to be decrypted, and none of the posts I've read are user friendly to a person with almost nill Crytpo experience.
I understand native encryption uses AES128, but I haven't found an explanation or program that will decrypt individual files.
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?
I used the IPhones hardware encryption to encrypt all my phone data, now on my Galaxy Note II I am wondering if there is something similar. Hardware? Software?
View 1 Replies View RelatedI'm interested in encrypting my phone (rootbox 4.2) including the external SD Card (if that's possible..?) but i need to know if you do it, then let's say you take that sd card out of the phone and plug it in your pc, how do you access the data? And is that still impossible to unencrypt the phone after it was encrypted (i mean on last android versions)?

View 1 Replies View RelatedIf you enable device encryption on devices with external sd card, the external sd card always remains unencrypted. As you cannot really control for every app where to store its data, you have some of your app-data on internal sd (encrypted) and some of you app-data on external sd (encrypted). To me this seems to be a security hole, concerning device encryption. why cm team does not include encryption for external sd cards, like some oems do? They put so much effort in security features and on the other side they leave parts of the local storage encrypted?

I ran the SQLite queries (had to pull the DB and edit on my PC, then push it back), generated a gesture key and pushed it to the phone, restarted and... no dice. The lock screen is still asking for a password to unlock it.

View 1 Replies View RelatedI set a password to encrypt the disk on my N4. When I reboot the phone it ask me a password with a standard keyboard.
My question is : can we change this keyboard for another one or at least its orientation?
the cause is that my screen is broken on the lower right coin and it block the "Done" button. annoying...
The TWRP keyboard to decrypt the disk should be fine (its "done" button is larger enough)
When I go to system settings -> security -> encrypt phone, with phone fully charged and plugged in and a suitable PIN set, the phone reboots back to lock screen but does not appear to do anything to actually encrypt the phone. After reboot, the option remains looking identical in the settings menu. No error messages or the like.
The lock screen works fine (PIN required), the PIN is suitably long, everything is updated, etc.
I'm not sure what the issue is. I rooted & changed ROM immediately on getting the phone (it's new), so I don't know whether it would've worked w/ stock bootloader / rom / etc.
I'm running:
Nexus 4 (android 4.2.2)
ParanoidAndroid 3.65 (pa_mako-3.65-20130712 + pa_gapps-full-4.2-20130710)
TWRP bootloader (openrecovery-twrp-2.6.0.0-mako)
the file, which defines the places included for a device encryption. Is it vold.fstab? I am asking, because I want my external SD also be part of the device encryption process.
Btw: I am running CM10.1.
So I screwed up and lost the passphrase for TB encryption. I have a good working android backup with all the apps+data that I would want to use for my next rom flash. The problem is when I go to TB and disable encryption on my good backup it doesn't allow me to restore the data when I flash a new rom. is there a way to completely remove TB and all of it's app data so that I can start from scratch with TB in order to good unencrypted backups of my apps+data without completely formatting my SD card? I'm stuck on my current rom setup.
View 1 Replies View RelatedSo the title may be a bit hard to comprehend but the gist of it is that I turned on full device encryption and since then when I transfer the pics off the phone to a computer they cannot be viewed. The message I get is corrupted metadata, the sizes on them seem right, I have not tried to view the exif data through a utility yet to see what exactly is corrupted.
I can still see the pics on the device, and share them online, but when I copy them off of the device they are broken. I've tried a couple of jpg recovery tools without any luck.
Most similar posts I've seen related to this is a corrupted sd cared (but this is on the internal one and only started after I turned encryption on).
And to confuse things a bit more, if I email the pic off it works correctly. So the problem seems to be just directly pulling them off the device, or browsing them when they are on the phone but connected to a machine. Same thing happens in linux and windows with various software.
If one enables full device encryption in Ice Cream Sandwich, am I correct in assuming that that the internal SD of that device is now not going to be available in the CWM recovery mode? And even if it was, the root fs would not be available? If so, this pretty much would make CWM flashing your device near impossible?
Does CWM even work if you use FDE? Or is it planned/
The question I guess is, when do you input your encryption password? Is it some pre-boot step?
I really want to enable device encryption but I can't find enugh details on how it works.

I have a Google Nexus 4 (rooted, of course) and I'm using the native phone encryption.
There is some information that can be found, revealing that google uses the native linux dmsetup tool for this.
Now, just in case anything goes wrong, I'd like to have a backup of the encryption master-key,
that I could use to restore the dm-crypt header.
On a normal linux system, this would be easy, only one call to dmsetup and I'm done.
However, I just can't find any info to do this on android.'
The UI doesn't offer this option (as is to be expected) and I just don't know how to do it by using adb.
I've opened a root shell session and tried some commands (dmsetup, cryptsetup, some calls to "vdc cryptfs", etc...), but I just don't find a way to do it.
I am running Android 4.1.1 on a Samsung GT-I9250M Galaxy Nexus.
Third, I have two carriers: a Straight Talk Unlimited Prepaid SIM (United States GSM/HSDPA) & a Claro Prepaid SIM (Honduras, GSM)
1) I installed the Straight Talk SIM in the phone.
2) I installed the battery in the phone.
3) I powered on the phone.
4) I enabled full disk encryption, choosing an easy-to-memorize password.
... over two weeks, i successfully decrypt the phone on boot 30 - 40 times with the password ...
... then i travel to honduras and purchase a Claro SIM ...
5) I powered off the phone.
6) I installed the Claro SIM in the phone.
7) When prompted to "type password to decrypt storage" I enter the correct password.
8) I am prompted to "try again."
9) I enter the correct password.
10) I m prompted to "try again."
11) I powered off the phone.
12) I installed the Straight Talk SIM in the phone.
13) When prompted to "type password to decrypt storage" I enter the correct password.
14) I am prompted to "try again."
15) I enter the correct password.
16) I am prompted to "try again"
I have tried booting with the Straight Talk SIM, the Claro SIM, and with no SIM. I have tried removing the battery. I am able to boot in Recovery Mode. However, performing a factory reset is not a viable option for me. I need to regain access to my phone. Why would the encryption key be altered by the SIM change? And wouldn't reinstalling the Straight Talk SIM be enough?
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.

View 3 Replies View RelatedI 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).

View 3 Replies View RelatedI 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: ?
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.

With JB 4.2.2, the native SIP dialer has always worked very well and I could place and receive calls (using my own Asterisk PBX server) without problems.
With the new JB 4.3 OTAs now, whenever I place or receive a call, the incoming audio is perfect but the outgoing voice sounds terrible: choppy and noisy to a point where the people on the other side can hardly understand what I'm saying.
I flashed both units back to JB 4.2.2 and the problem went away, no matter the configuration or the apps installed. Conversely, I can always replicate the problem with JB 4.3, clean setup, no additional apps or services.
I'm interested in an app to decompile apps within android.

View 6 Replies View RelatedI recently received the OTA update to my Eris and am loving the new interface. However every time I want to unlock my phone I am now required to enter an 8 digit password as opposed to the screen pattern I was using prior. From messing around I realized that this is due to the fact that my company's exchange account requires SSL encryption and therefore requires the password be entered to unlock the phone. My question is whether there is a way to keep my email but only require the screen pattern to unlock my phone? I know iPhone users at my company that are still fine entering their 4 digit code so have to assume we should be able to do the same.
