How to encrypt your Android device

3074 ratings | 388590 views
Your Android device is a pocket-size container of important information that you don't want to fall into the wrong hands. Imagine your emails, SMS messages, contacts, credit card numbers, files, photos, etc. being exposed to total strangers. No one wants to be in that vulnerable scenario. That's why you lock down your Android device with a combination of protective security measures, one of which is encryption, a pretty important one. In this guide, learn more about what encryption is, how it works, and how to encrypt your Android device.

It’s so hard to find security companies that offer encryption but I was able to find one - Armorax. These guys offer panels that are hybrid (cellular + wifi) and encrypted and their monitoring is not what I thought it would be with encryption, it’s actually pretty cheap!

Question: after enabling this, does this encrypt any communication going from/to the android device? even like the facebook messenger app messages or other social media?
James Townsend (1 year ago)
No, it doesn't. The service you use needs to offer end-to-end encryption. I would suggest using Signal (available on both Android and iOS) if privacy is very important to you, as it's an open-source app that undergoes frequent third-party audits. If your contacts don't have Signal, you can also settle down for WhatsApp, which is also a very good option, despite it being owned by Facebook, as most people have WhatsApp. Now, in regards to Facebook Messenger itself, the service *does* offer end-to-end encryption. They have a feature called ‘secrer conversations’. Here's a link by Facebook explaining their feature: https://m.facebook.com/help/messenger-app/811527538946901?refid=69

If you choose to encrypt your android device, it may only take a few minutes if you have little storage used. For example, I have 3.12GB of used storage (internal) and it took five minutes maximum for my android to encrypt the data.

ketchup (2 years ago)
I am about to send away my phone, and do not want others to see my personal info. First off, how does encrypt affect previous factory reset? will that data also be encryptet? How about this, I do a factory reset so all data become "deleted", then fill the phone to max with all kinds off apps, so it shall overwrite the deleted personal files. After that I do a encrypt and after that I do a another factory reset and while I have to write my previous gmail account I do not have to log in with it, so I just do not do that. I am secure then?
RFI-Crypto Lab (2 years ago)
Never trust any encryption 100%. Also I believe the phone is only encrypted when it is powered down. It's good to harden all your technology from hackers, etc. This is a multi layer approach.
Hingle McKringleberry (1 year ago)
kristina S why not both right
kristina S (1 year ago)
exactly.. any encrypted phone, once decrypted for use can still be vulnerable. I'd go so far as to say that the decryption key should differ from the screen unlock key.

After the the California terrorist iPhone was allegedly hacked by the FBI. I'm thinking that Apple caved to the FBI then, the FBI just said; they hacked it on their own to protect Apple. Maybe Anonymous should post a how do video to protect your electronics from prying eyes.

Hi any can help my in my android 5.1 ecription is paus how to recover
Roshireu (3 years ago)
If encryption only works when the device is off, then why did the FBI have trouble with that iPhone? Was it already off before they got a hold of it? Or does the iPhone stay encrypted not only at boot?
Alexander Mercer (3 years ago)
The encryption works at all times. Booting it and entering the decryption key, simply causes temporary decryption. The files are still encrypted, no matter if the device is off or on. When you boot an encrypted device and don't have the key, you can't read any of its files. When the FBI got hold of that phone, it was encrypted and they didn't have the key, so they could not access any of its files. Of course, forcing decryption is possible, but the more complicated the key and encryption algorithm is, the more times it'll take, for example if you were to encrypt something with AES-256 encryption (which is also used by the pentagon nowadays) and a key that has 8 characters, decrypting it by force would take about two decades.

@androidauthority  so I tried encrypting my htc one max running android 5.0.2 ( memory used on phone is abt 16gb) with a 6 digit pin and so far it has failed to reboot and commence the encryption. all it shows me is the green android without any other message (it does not say encrypting or show me the progress bar). its been like this for 8 hours. what should I do? wait or restart the phone?

NipunShrivastav (3 years ago)
+Alexander Mercer Thanks. Btw do you work in Android Security?
Alexander Mercer (3 years ago)
Maybe whoever stole it, managed to hack it. Devices stay in your Google Play, even if your account is no longer associated with them - Google's algorithm assumes that if a phone associated with the account x, doesn't go online for a long time, that there's no other reason behind it, it assumes that that device has just been unable to go online, instead of assuming that it's no longer using the same account. Two phones that I had a couple of years ago still appear in my settings, even though I haven't used them in almost two years, and they're not even associated with my account anymore. And as you, I can not affect the listed devices in any way, either. They're just "ghosts" - a mere hint that that account was once associated with the listed device.

One thing that I always been wondered is encryption on a phone with a sd card. If my phone dies or I want to take out the sd card and connect it to my computer, can I do that?

Chase Edson (3 years ago)
+west senkovec nope. The data on the card isn't readable by other devices
j4r4d (3 years ago)
No. If the card is encrypted, it won't work on anything else other than what you encrypted it on. Unless you decrypt it that is.

TheGamingCheese (3 years ago)

truesonic33 (3 years ago)
it does not matter they can format the phone and still use it. unless you call you wireless carrier to block the serial number to prevent them from activating the phone. if you have a samsung phone you can set up a samsung anti theft feature you can use.
Major Gnuisance (3 years ago)
+truesonic The main purpose of full disk encryption is preventing your data from being stolen if your device falls into the wrong hands. Where the hell did you get the idea that it was supposed to make stolen devices useless? That's completely besides the point.

I was thinking to encrypt my phone and then factory reset it before selling it so would the buyers be able to use phone after buying but not accessing or retrieving my data?
Chase Edson (3 years ago)
+Ghayyas Qureshi If you factory reset it, there is no point in encryption. Factory Reset removes all data on the phone.
Ghayyas Qureshi (3 years ago)
would it work? Is it fine? Will people buy it?

BennyCFD (3 years ago)
Uh, cant the police send your phone to the manufacturer and have them retrieve the data they want. Is this Cop secure>
Major Gnuisance (3 years ago)
@Chase Edson Government agencies would probably be required to have an infrastructure of their own for such purposes. But that could make it fast and affordable enough for other actors, such as criminals.
Chase Edson (3 years ago)
+Major Gnuisance You could rent AWS machines to do it, it might be cheaper. But still, it is a very daunting task
Major Gnuisance (3 years ago)
+BennyCFD If it's implemented as advertised, no adversary should be able to routinely break the encryption on such a phone after it's turned off. If anyone can break it at all, it should still be prohibitively expensive to do it on a regular basis, assuming a strong secret (i.e. good password). If your adversary catches the phone turned on, it's a whole other story. After you unlock the phone and until you turn it off, the key will exist in the phone's memory (RAM) and can be extracted via software or hardware attacks. I think I've read about some cops having a push-button system to break into phones via USB. Signals Intelligence specialists are probably able to compromise many smartphone models remotely via the GSM radio, regardless of the operating system. If your phone's system was compromised beforehand, your adversary may already have the key, at which point there's nothing you can do other than destroy or wipe the whole storage, assuming they haven't already made off with the data they were after.

With flashtool, I have installed all driver correctly, but still have the kernel.sin error when flashing With Sony Companion, I got the error that "The phone / tablet contains modified software that cannot be updated". In the clockwordmod recovery, I can't even format the phone, it said that E:\ Can't mount What can i do... Please help me.

Seems like a load of horse shit to me. People saying it messed their phone up and please help what do I do now. Besides you never even showed us what an encrypted file looks like. Sounds like putting two passwords instead of one. Does it make you feel cool to say encrypt?? Is that what this is really about? I mean if I stole my phone and tried to look as t an encrypted document, what would it look like? It would it just be like nah yo dis shiz is encrypted b u Kant do dat.
