Today i encrypt my rooted stock Xperia z5c 32.2.A.5.11 Marshmallow rom. I set a pin code for lockscreen and this pin is now the same for the device encryption. Those two are bound together due Sony limitations. Because of security reasons and for simple use i want a password for disc encryption and a pin for the lockscreen.
I tried the Apps "snoopsnitch" and "cryptfs password" to change the disc encryption password but this results in an password error in the encryption screen. The device can't decrypt at boot.
The terminal command
su vdc cryptfs changepw password [newpassword]
works, but after changing the passphrase the System doesn't recognize them and can't decrypt too. I tried multiple passwords including the translation to hex of them without success.
Does anybody know a solution or got the same problem?
Thx

Hi
I've followed the instructions from Nexus offical guide and installed my personal certificate stored in a pfx file (PKCS#12) in my Google Nexus (ICS 4.0.4). At this point I faced a little problem: the new certificate is not listed in "User" tab in "Credentials". It works anyway because I can use it in web pages.
But the big problem IMHO, is the way Android protects your certificates. It only requests the user to set a pattern, PIN, or password to unlock the screen. I'm missing a password-protected access to my credentials like IE does in Windows, for instance every time your certificate is requested by a web site.
Is there a method to enhance security of your certificates in ICS and set a password for accessing certificates storage?
Thank you
Hello,
To recreate issue:
1. Start 2-factor authentication
2. Generate app-specific code
3. Use that to sign into your device
4. Change the SIM
I have two SIMs, and I sometimes switch between them. The issue is that once I do so, it prompts for the password. I then have to create a new app-specific password using my computer to access GMail.
Is there any way to fix this bug? If so, how can I do it?
I appreciate any help.
Hi all,
My problem is the following: my phone's screen is dead, the phone has full disk encryption turned on, I know the password, I need to retrieve data on it and I have an encrypted back up.
The phone is a Samsung Galaxy S7. I cannot access files by plugging the phone into my computer as I can't unlock the phone without the help of the screen. USB debugging is not enabled.
I have a recent backup of the files made with Samsung's Smart Switch. However, all apk files as well as most files are saved as "enc." files and not readable decrypted files.
I have tried using gpg and openssl tools to decrypt those files individually with the FDE password of the phone without any success.
What are my options to A) either access my phone's content without the use of the screen B) or decrypt those encrypted backed up files I have given that I know the phone's password?
Thanks
I wanted to have a separate encryption password and lockscreen pin on my android 9 (Pie) smartphone.
As Google removed the features from "vdc" to set an encryption password on the shell, I started experimenting.
I tried instead to copy the only thing that looks like it could be the password in /data/system/locksettings.db, i.e. "sp-handle". So I changed the PIN (and encryption PIN), then I set back the "sp-handle" entry.
As this did not work, I deleted lockscreen.db.
When I deleted lockscreen.db, I was able to set a new PIN independend on the encryption pin.
But now I cannot change my encryption password anymore!
I tried changing the pin back to the encryption password and then changing to the new password (so the last change would not provide the correct "current password" to a password change API), but it does not work.
So I can currently boot with my current encryption password and login with lockscreen pins I can change as I want, but I do not have an option to change the encryption password anymore.
Maybe I deleted a "this pin applies to encryption as well" flag together with the old locksettings.db.
How do I couple lockscreen PIN and encryption PIN again or how do I change the encryption PIN manually, so I can set a new encryption PIN?
My ROM is lineage-16.0 on a Xiaomi MI A2 device.
Recently, I don't know why but a message popped up asking me to enter an alphabetic password even though I didn't set any. To unlock the phone I had: fingerprint, face and 4 digit PIN.
I was hoping that after a reboot it would not require an alphabetic password just the 4-digit PIN (only the numeric keypad was displayed) as always, unfortunately there is a message: "Password Must Be Entered After Device Restarts".
OnePlus service said that if I send the phone to them they will still clear it of data.
After connecting to the computer, the commands:
adb devices
fastboot devices
Click to expand...
Click to collapse
don't detect the phone, whether in normal mode or recovery mode.
Is there any way to recover at least some of the data before I do the format? Or is there any tool that will bypass entering the password ?
A data recovery specialist might be able to.
Always back up critical data redundantly, regularly to multiple hdds that are physically and electronically isolated from each other and the PC. At the very least use a OTG flashstick. If you had an encrypted SD card used as a data drive you probably still have access. SD card slots are far for obsolete but Android is becoming less usable by the year. Thanks Gookill.
I just send it in...
