Ive read this can be done incase your external sd card is stolen or lost where u can passcode encrypt the entire card where if someone trys to view jpgs images or video anything for that matter they get a blank image..
Is this a Computer pc encryption deal or native to being done right from the device or an app.
And are they're any downsides to doing it and being able to view yourself from your device while encrypted

Settings -> Security -> Encrypt External SD Card (and Encrypt Device).
Keep in mind that it's not worth much if your phone is turned on when the attacker steals it. No matter what.
Against the ordinary thief it'll do fine.
Soooo
stealing the phone gives the person 100% access to the SD card? atleast the iphone has the numeric or alphanumeric password feature and 10 mistakes before Wipe.

Absolutely right. Still looking for a way to lock out federal forces in case my phone gets "arrested". Any ideas or recommendations?
Encryption of external sd... still is supposed to make any file on sd pass code required. .. as in if someone takes the card out tries it in a pc or other phone they'll see black or blank images .
Essentially making it like Iphone proof .
Only thing can be done is a fat 32 format to clear card.
But I havent tried cause I don't wanna take risks of loosing vital info .
As far as the last post about federal people compromising your phone .... well trust me if they get your phone they can hack anything

what you really need is truecrypt.org/
It might be possible to port it to Android and then use it on the SD card.
In fact it appears it has been done here: code.google.com/p/cryptonite/
stupid 10 message posting crap gawd, someone covert those to real links for people.

It seems to only encrypt sdcard contents. I'd probably want my /data encrypted as well.

I once hacked me an EncFS-script that mounts an encrypted folder on my sdcard as sdcard0 and the rest of the sdcard as sdcard1. I use it on my phone since more than a year now without any problems:
http://forum.xda-developers.com/htc-sensation/development/mod-encrypt-sdcard-encfs-t3027711
It may run without any changes on your phone, too. Otherwise you only have to change some paths in the script or ask me for help.

Thanks for the advice. By looking at that thread I see that you are using encFS. What i have in mind is a full partition encryption (just like LUKS, for instance). Do you know if that would be possible?

I think by "full partition encryption" you mean "encryption of the file system".? Because if you only mean encryption of "all files on the sdcard" - that's what I actually do. I also wrote three points about my decision for EncFS.
You could try to use TrueCrypt in the same way I use EncFS, but with an encrypted partition. Apart from that I'm not aware of any (easy) way to encrypt the file system. Android uses dm-crypt for internal encryption, but I don't know if and how you can use it to encrypt the sdcard.
The latest luks manager (2.5.1) allows you to encrypt external sdcard, which should me mounted on boot or manually and unlike Encfs, no password is stored in plain text. To have a password stored in plain text is no security at all.

I wanted to prevent access to the data on my sdcard if I lose my device. The password is stored on encrypted /data, only readable by root. In what way do you consider that "no security at all"?

In 2 ways: First, a security model that relies on a separate encryption process that is not provided in that model is not secure. What if data partition is not encrypted? Second, you can't rely on permissions only, if permissions alone were enough, we wouldn't need disk encryption at all. Textsecure used to have a glaring security hole: all sms were stored on disk in plain text. Moxie didn't say encrypt your data, he instead fixed the issue.

You still remember? I meant no offence.
Adopted storage: even if this is true, it is still OK, because I don't think you can encrypt adopted storage without encrypting data partition. In other words, there is no way in M the encryption key could be read without first decrypting data. In your case, it is possible, since encrypting SD is independent from encrypting internal data partition. But if I were Google, I would still not save the encryption key in plain...
Hey everyone,
I am wanting to encrypt my D6616. So, a couple of questions:
If I encrypt the phone without the SD card, can I encrypt the SD card later?
If I encrypt the device, can I decrypt it?
Lastly, if you know your PIN, can you recover from a factory reset on your SD card?
Thanks everyone,

1. I am pretty sure, Yes
2. Yes, but during startup, so it would pay to copy the contents to a computer if you wish to remove encryption. then you have to factory reset.
If you go through the process, it will advise you just prior to starting the encryption
@danw_oz,
Thanks for the reply.
I assume that decrypting wouldn't require any external intervention... i.e. there are menu prompts under Security that will do it as opposed to using the shell, etc.

@danw_oz,
According to the article you've provided, there is no decryption, unlike what you've informed:
"Encryption is One-Way Only: After encrypting your device’s storage, you can only disable encryption by resetting your phone to its factory default settings. This will also erase all the data stored on your phone, so you’ll have to set it up from scratch."
If your Z3/Z3C is encrypted... do you have a decrypt option now?
Thanks.
Johnathan
Evidently the process isn't reversible... at least during the encryption process, it informs before confirming that it is irreversible.

The decryption occurs during entering of your pin or password, at which time you would need to copy anything you want to keep off the phone onto a computer.

To be honest there is no real benefit of this over just locking your phone, because if you loose your phone it can still be hacked until it is rebooted. If you have find my xperia, you can erase the phone which I am sure includes the SD Card

I understand your reply. The data has to be decrypted before it can be used by the phone and other apps, etc, this only makes logical sense to use decrypted data. since it can't used encrypted data.
I suppose I should have been more clear in my original posting. Once a phone has been encrypted, can the encryption be removed to use the data in its decrypted form? i.e. if I encrypt my SD card, decrypt it, remove it, then place it elsewhere to be used in other devices... the answer is no. Once encrypted, the encryption can't be removed to allow the card to be used elsewhere.... without losing all of the data.
Sorry for the miscommunication.

Hello every one,
I have a complicated situation with deleted files (photos and videos) recovery,
Phone : Nexus 5
Android: M (6.0) BN: (MRA58N)
Root/unlock: Unrooted and Unlocked
Some one has deleted all the files in the camera folder in the gallery, i want to restore these deleted files. After hours of digging the internet, i found a lot of applications that doesn't work (almost all of it either require root or require USB Mass storage), and as you know we are only able to connect to the PC using MTP protocol.
Rooting the device requires unlocking it which will cause the whole phone to be wiped.
I have two questions:
1) Is there any (REAL) way to recover the deleted files (Images and videos) with the current circumstances (Unrooted, Unlocked, MTP Connection) ?
2) If the answer of question 1 is NO, if i unlocked (and for sure wiped) the phone then rooted it, can i still have the ability to recover these files, i mean how badly the wipping process will affect the internal phone storage?
I really appreciate your help in advance.
Best regards,

phones uses emmc nand cards, they are basicly ssds, no mechanical parts, instant access time, etc... . because of that,when a file is deleted, its actually deleted, not just "masked".
and if you unlock, you delete all userdata, apps,files,etc, no way of recovering. Altought on early n4s bootloader the wipe was glitched(you could restore your data), on the n5 it fully wipes

i don´t know about the bootloader unlock part wiping the data on the M8 (since those were never sold here in Brazil) however the rest still applies. on HDDs and other mechanical drives, the deletation process is just removing the file from the index on the drive, so it cant find anymore, thats due to mechanical drives having fragmentation, not instant access times and other things(such as lower read/write speeds, bad sectors, etc). since those dont apply to solid state devices, such as ssds or emmcs, every file operation is permanent
Hi everyone,
i hope someone can help me with my Question.
Is the Mate9 encrypted by default?
Unfortunately there is no Option to encrypt the Phone manually.
Which enryption Type will be used? File Based or Full?
Will SD-Cards encrypted by default?
Is there any way to check this?
Update:
The Mate 9 is NOT encrypted.
This will be available in the future.
Pretty sad
Mate 9 is loaded with Android 7.0 Nougat which uses File-based Encryption by default rather than Full-Disk Encryption.
http://www.howtogeek.com/269422/how...ats-direct-boot-for-less-annoying-encryption/
For SD card, I don't know because I don't use SD card on my device.
no sorry, i called the Huawei Support Hotline, the Mate internal storage is not encrypted.
Only the SD Card can be encrypted.
btw: in the developer section there isn´t the point "convert to file encryption"

Sent from my Huawei Mate 9 using XDA Labs
Internal storage is not encrypted by default? That's kinda surprising and disappointing considering how much Huawei was talking about security in their last few events. The file-based encryption should have a negligible performance impact.
Try : settings - fingerprint ID - fingerprint administration - security access - Enable - internal memory / Sd card
Yo can enable encryption there
Enviado desde mi MHA-L29
i think this is not real encryption, this is only a "passcode / fingerprint" safe

Not to get political here but you do know where the Mate series is made? The Chinese Government doesn't want device encryption - so it's not there. And even if it was, I wouldn't trust it.
i dont see this setting. may have to return the phone if i cant encrypt the whole device.

I can't say whether it is or isn't, but if I go to Settings, Memory & Storage, Default location, and try to switch the default from internal to SD card, I get a message saying my phone has been encrypted and to make sure the external storage is too before proceeding.
Everydevice which comes with nougat installed from huawei is encrypted with (filebased encryption) and every device which gets nougat update like honor 8 and p9 etc gets full diskencryption so the statement is false it's encrypted. The full disk encryption is one encryption step.
The filebased encryption is two way encryption. It uses default hard disk encryption and per app encryption so yes it's encrypted.

I would like to add that we are talking about the encryption of the /data partition only.
Other parts of your internal memory (like /system) or the SD card are *not* encrpyted
Code:
> adb shell mount | grep cryp
/dev/block/bootdevice/by-name/userdata on /data type f2fs (rw,seclabel,nosuid,nodev,noatime,background_gc=on,discard,user_xattr,inline_xattr,acl,inline_data,extent_cache,[B]inline_encrypt[/B],active_logs=6)
File-based encryption should still be active on internal storage unless you have rooted.

Well technically yes since on nougat it should encrypt all files on storage. Isn't it how it is? Because you still can get into internal storage but files are random names right?
Also I don't see why phone would encrypt your external sd because usually when setup you don't have any sd card inserted so why only /data partition is encrypted is how it should be since u have an option to encrypt external

Everything but magisk.img and /data/magisk/ is encrypted in /data and it runs fine.

How I unbricked "Decryption unsuccessful" The password is correct but... (Apps2SD)
Hello, I don't usually post in tech forums, I usually the guy that only reads,
but this is the time when i could not find the straight answer to my problem and had to google the solution out of similar posts, so I decided to glue everything together and write my solution to this particular situation,
so I might save a lot of time to someone who got in exact or similar situation.
Sorry for my crappy English, but here we go.
What this post trying to solve:
You stuck at boot loop: "Decryption unsuccessful" The password that you entered is correct but unfortunately your data is corrupt.
and how to make it work Apps2SD with Huawei P9 SD card with enabled password protection.
Basically my Huawei P9 (EVA L-19) with Android 7.0 Nougat got running out of internal space, and i am really a heavy user on apps. Kirin 955 handles just fine as long as it has at least 10Gb of internal free space.
I have SD card 64Gb, but huawei stopped support, native move apps to SD, long time ago. My device is rooted, so I was searching for a solution. There is few apps that can transfer your internal memory apps to SD by using root, but the one that actually worked for me is Apps2SD. The thing is, my SD card is password protected (Huawei native function) I want to keep this function in case of device getting stolen.
Problem is, many third party apps that move your apps to SD, does not know anything about Huaweis SD card password feature. In fact (as far as i tested) only Huawei phone allows you to enter password and show contents of SD card, no PC, or for example Samsung phone will recognize this SD card.
So i was messing with Apps2SD, partitioned my SD card in to 2 primary partitions, 1- exfat, 2- Ext3. It works kinda fine, but after reboot, there is delay, Huawei unlocks SD card after main boot part, and Apps2SD does not understand this and show that it failed to mount second partition.
In this case, Apps2SD starts giving you solutions, one of them is this ADVANCED mounting option. It does not tells u about any dangers, nothing really.
I chose that option to see if it will be able to see second partition contents faster, rebooted - boom bricked.
You see the message: "Decryption unsuccessful" and asks you for decryption password. It might be SD card password, not sure, it does not matter, because you can type ANYTHING and it always say:
"The password that you entered is correct but unfortunately your data is corrupt". And gives you only option: fully data factory reset. Now hold your horses, dont press that. I just knew that this is bull**** and no way
my personal data is corrupted, its just some hadshake issue. (I was right i fully recovered everything up n running)
Assuming you got in this mess, your device must be rooted and you probably have TWRP recovery, cause Apps2SD work only with rooted devices.
To recover from "Decryption unsuccessful" boot message and restore all data and settings:
Got to TWRP recovery by holding power button and volume UP (after phone vibrates, hold both buttons 2sec more and then release power button, and then after 2sec more release volume up, cause if
you do this too fast, u will end up in wifi recovery by Huawei, and it wont work anyway cause your device rooted).
Then go to advanced and file manager, locate sdcard folder (this will be internal memory, not external), you should be able to see all of your personal files! Copy them to flash drive by connecting with OTG.
What we gonna do now is: do a full nandroid backup: TWRP, backup, check: BOOT, SYSTEM, DATA. and do a backup to flash drive connected with OTG or hard drive if it works for u.
After backup is done, go to WIPE, select format data, select DATA partition and see what original file system it uses. Now format in any other system, then reformat again to your original file system.
DATA partition somehow lost its encryption handshake key and this caused the problem, reformatting fixes it.
Now do a full wipe as if you would install new rom, wipe: system, data, storage, cache, dalvic cache.
Restore your previous nandroid backup, reboot to system,now your phone should boot with all the apps and settings just as you left.
You might be missing some pictures and other media in main storage, just connect your P9 with usb cable to pc, and restore previously backed up media from flash drive manually in pc interface (copy paste, replace all),
some small minority files might wont copy, don't worry about it, Im not sure but they are mostly indexing files, all ur media will be back in place.
Now, how to make Apps2SD work with this configuration?
Don't use that advanced method to find SD cards second partition, use any of first 3, the 3rd one worked for me just fine, cause its SU library based one.
Don't move your apps fully to SD, or they will "disappear", move everything except APK, ODEX, DEX (Lib is optional, you usually can move this one just fine). SO basically app core will stay in main storage but cache and app data will be on second SD card. This way, after you reboot your phone, you will have to wait like 3mins and App2SD will link your files to apps itself just fine. It might will show some errors right after reboot, but after Huawei unlocks its card, files will be linked, and apps wont be "gone" cause app core still stays in main storage.
This way i managed to save a lot of space and move most of app storage to SD card, P9 became very responsive, even in 2018 this is a really fast smartphone.
Sorry for a messy post, I'm not a writer, but I hope this helps to someone!
Thanks a lot, you saved my phone-config! ) This step "...and see what original file system it uses. Now format in any other system, then reformat again to your original file system." was unclear to me, as TWRP didn't give me the option to choose a file system, but in the end it worked out fine without just as well.

If it was due to updating Magisk to v19.x (on Huawei with Nougat / EMUI 5)?
In that case, there is an easier solution, just flash back Boot img with Magisk v18 1 and everything will continue to work as it did (without any need to reformat, factory reset, etc), see

I'm not entirely sure what caused it, but I suspect Apps2SD just like in the original post (I installed/tried to use it shortly before the problem occured).
