over a simple password screen lock: nobody can take the internal memory of my phone out of the phone itself. So what is the advantage of 1. over a simple screen lock with password + SIM code lock?
Understand that encryption is used to protect the data from unauthorized access (device misplaced or lost or alike situations). If you are sure that the device ...
nobody can take the internal memory of my phone out of the phone itself
While taking out your phone's internal storage out is harder than the SD card, it's definitely not impossible. Rework stations used to extract chips from circuit boards may be expensive, but not outrageously so (around $1000), and can be rented in many electronic repair shops for tens ...
Yes, custom recovery works with encrypted honeycomb device. The built-in encryption doesn't touch ROM & firmware at all. It just encrypts accounts, settings, downloaded apps & their data etc. which can be located on phone memory, internal SD or external SD. That's why encryption is no longer present after factory reset because there's no encrypted ...
On my encrypted Nexus S I use a temporary tmpfs mount on /sdcard in CWM. It has enough RAM to hold the new ROM in memory during the update:
Download your ROM to /tmp/update.zip and boot into recovery. Then log in via 'adb shell':
## on the host machine do:
me@workstation:/tmp$ adb shell
## now on the device in 'adb shell' mode...
~ # mount -t tmpfs none /...
Marshmallow has two ways to treat the external SD card :
Portable Storage : In this the entire memory of the ext.SD card is available for use, if it is not encrypted (natively) and you can mount it on your PC to read/ transfer contents
Adoptable-storage: In this the ext. SD is treated as a part of the phone and when you encrypt the phone, the ext. SD card ...
The answer for me involved a number of things, but I think one is really the key.
Use the "recovery" Command, bro
This uses CyanogenMod's/AOSP's recovery program to wipe the user data and disable encryption. (found in this answer on Stack Overflow) Boot into your recovery, and then from your computer run
adb shell recovery --wipe_data --...
A lot of people are asking that question. Here's one.
Some people are offering bounties. Like at XDA-Developers.
Some people have suggested alternatives. AxCrypt looks like an alternative, and there's an alpha product that works with it (and Dropbox) called BoxCryptor.
But I've not found an actual port of Truecrypt to Android, nor any information about ...
Your encryption password is the same as the pattern/PIN/password you use to lock your screen. So simply go to Settings > Security > Screen lock and change it. Note that when you do this Android will ask you whether to also enter the pattern/PIN/password when you start the device in order to make your encrypted device's data unreadable without it.
In Android ...
I can confirm with 100% certainty that the numbers are indeed 1-9 for the pattern unlock.
My Nexus 4 met the same unfortunate end (except on concrete) and after some Googling, I found this post and was able to follow personne3000's answer in order to mount my pattern-encrypted userdata partition.
I'm running Ubuntu 15.04 x64 and had to apt-get install ...
Google has no idea what the encryption key for your device is. The entire process takes place on your device and the key is never transmitted anywhere. The key itself is also not stored in plaintext on your device:
Storing the encrypted key
The encrypted key is stored in the crypto
metadata. Hardware backing is implemented by using Trusted ...
There are three ways to identify which encryption type is used:
Identification by device behavior
As a user you should be able to identify what encryption scheme is used by the behavior of your device when it boots (e.g. because you restarted it).
If the classic Full Disk Encryption is active your device will boot for some time and then present a special ...
The current encryption scheme is outlined on the Android website's "Notes on the implementation of encryption in Android 3.0" page. From that page, the specific algorithm used is noted as such:
The actual encryption used for the filesystem for first release is 128
AES with CBC and ESSIV:SHA256
That's the only official documentation I've seen for it at ...
In Honeycomb the option is in Settings -> Location and security. In Ice Cream Sandwich it's at Settings -> Personal -> Security -> Encryption.
If you're wondering about how Android does encryption, take a look at this: http://source.android.com/tech/encryption/android_crypto_implementation.html

There are many available choices, depending on the features you need:
Cryptonite uses EncFS and requires root
LUKS also requires root and provides on-the-fly encryption (AES by default) to virtual folders
Eds provides encrypted containers and does not require root. It even is compatible to TrueCrypt.
DroidCrypt can encrypt single files or full directories. ...
Interesting question, let's just try it out in a practical test. I connected to my device (running Android 5.1.1 Lollipop) through ADB over Wi-Fi using adb connect 10.0.0.10 and ran some tests. What you are seeing is the output of the packets that I captured using Wireshark.

Press Power Button to select it

Encryption is a fairly CPU intensive process, so using more battery is not unexpected. Though it depends a lot upon the apps you use and how much they read/write to the storage. I would expect that an 'idle' Xoom with encryption would last just as long as one without, but if you use an app that does lots of little writes to disk, it will end up using more ...
I sent this question into Verizon Wireless as well. Here is their reply:
Thank you for contacting Verizon Wireless through our website...I
understand that you've been having an issue trying to decrypt files on
your handset. At this time Motorola hasn't provided an update for
your phone to be able to do this. Without that, we're unable to
Reposting answer for future people!
Naturally, I figured it out 10 minutes after posting.
Can't answer for another few hours because I'm a new user. Under the security section of the settings, there is a Device Administrator page.
I deactivated the "Email" app as an admin. It warned that it would delete all my mail and stuff and I accepted. No factory ...
Goggle Drive gives you some security options regarding your documents:
You can choose to encrypt all offline documents (that is, documents
stored on your device);
And can also choose to decrypt documents incrementally as they are
streamed to your phone, by selecting the Streaming Decryption, thus having just a small portion of the document decrypted when ...
Android provides the capability to do filesystem encryption, but it's up to the vendor who builds the firmware for your device to enable it for the SD card. I have only seen a few devices with this capability enabled for the SD card, though most seem to have it for the internal storage (/data). Typically if it's enabled, there will be a menu item in the ...
The encryption of the SD card is a device-specific subject, but as far as Android goes, only /data gets encrypted.
Android default behaviour:
By "default", for Android, the encryption on the device is applied to /data only. This because all installed applications that get moved to the SD card are already encrypted and only usable at that specific ...
I have the same problem when sending encrypted mails from my Apple Mail client with GPGMail2 plug-in.
Apparently K9-Mail supports only PGP/Inline and not PGP/MIME which seems to be the standard formatting PGP-Emails today.
If you like to test it on your own, configure GPGMail to use inline mode through your Terminal:
defaults write org.gpgtools.gpgmail ...
On my Moto G 3rd Gen (osprey), neither calling recovery nor wiping LUKS header (at start and end of partition) worked - I still needed to enter the encryption password during Cyanogen Mod bootup, then was stuck with an "encryption error" message.
I finally found that my TWRP 3.0.1 recovery has a "Format Data" option in the "Wipe" section. This does a ...
There are low(er)-level commands that can be used in a shell to encrypt your user data partition. Disclaimer/Warning: the following instructions will wipe your data, ensure that you make a backup if needed.
Following these steps, you should be able to wipe your data partition and have it encrypted afterwards (similar to a factory reset):
