Hi all, i see that many roms are for decpryted devices only. I never understand what dectyprion is.
How i can see if my device is decrypted? Which are the benefits? Can i switch from decrypted to encrypted every time that i want? How i can do that?
Here is some information on what encryption is:

Hi,
I've got a Archos 101 G9 (ICS 4, rooted) and I can't find the full system encryption option in the settings / security menu.
Does anyone know why the device encryption has been removed or disabled by Archos? Is there any way to use it?
I've also tried [email protected], but it's not only disabled in the stock rom...
Many thanks!
AFAIK encryption is not present in all Gen9 ICS firmwares (can't say if ICS doesn't support it or if Archos didn't include it)
hmm... does anyone know whether the encryption can be activated in an other way? or is there a better way to encrypt a tablet?
Jellybean lists as one on the new features that it will periodically remind the user to decrypt the device.
But it doesn't say WHY.
I gave Googled and searched forums and all I can see are references to the feature and help on encrypting and decrypting.
No one ever mentions why it was important for jellybean to remind the user to decrypt periodically.
Does anyone know WHY this feature was added or why I should decrypt?
Hi,
I've been using UltimaROM v12.0 with device encryption no problem. I switched off device encryption and proceeded to factory reset/flash v15.0 and have since restarted only to find my S3 asking for an encryption phrase.
Not sure what's happening here, I've tried the passphrase I've been using multiple times and it just says try again. I don't understand why it thinks the file system is encrypted, I can browse the file system within CWM/TWRP without it asking for an encryption phrase, but when I do a normal boot it comes up with the password prompt?
Any advice? Thanks.
Hi,
I just bought Samsung Galaxy Note 3 and want to setup it like my old Galaxy Nexus. Also I want to stay with fully stock ROM for a while so I need to perform everything without root.
I need encryption set on my phone. Problem was that for some reason Samsung ROM does not allow PIN unlock on encrypted device. Password wasn't convenient so I searched for workaround for this.
Solution was to install Tasker+Secure Settings and change lock type to PIN just once. Everything was perfect, PIN lock was set permanently. BUT, when I rebooted the phone I wasn't able to decrypt storage with old password. My device can be only decrypted with new PIN now.
How the hell that could be? I believed that when I set encryption password it will be used for decryption. Obviously for me now, it's not.
My question is: what encryption key is used for data decryption in Android? You can change password or PIN and decrypt device with it easily. In other words: what data (encryption key) should be hacked in order to decrypt the phone and where is it?
Nowadays, does encryption password size really matters on a security perspective?
Brute force or other methods still breaks device encryption? If so, how to stay safe?
Device is a Galaxy Note 8 on Android 8, but this is a relevant topic to every device.
