About Cryptfs Password APK

Description
Changes the Android disk encryption passwordNew: Experimental Lollipop support. Requires SuperSU
If you are using a pattern lock, enter the current password as
a sequence of dot numbers.
Dots are numbered left-to-right, top-to-bottom, starting with 1:
1 2 3
4 5 6
7 8 9
This tool REQUIRES root access to work. If you are not using disk encryption this tool will not be useful to you. In fact, it will not even start on your device.
*** WARNING ***
If you forget the new password after you change it, you will not be able to boot the device. You will have to perform a factory reset, DELETING all your data. Make sure you take a full backup before using this tool, and REMEMBER THE PASSWORD. You have been warned, use at your own risk!
Android 3.0 (Honeycomb) introduced disk encryption and it has been available on all subsequent versions. It encrypts the data partition with a key protected by a user-selected password and requires entering the password in order to boot the device. However, Android uses the device unlock password or PIN as the device encryption password, and doesn't allow you to change them separately. This effectively forces you to use a simple password, since you have to enter it each time you unlock your device, usually dozens of times a day. This tool allows you to change the encryption password to a more secure one, without affecting the screen unlock password/PIN. To change the device encryption password simply:
1. Enter the current password
(initially the same as the unlock password/PIN)
2. Enter and confirm the new password
3. Hit 'Change password'
The changes take effect immediately, but you will only be required to enter the new password the next time you boot your device. Make sure you choose a good password, not based on a dictionary word, since automated tools can brute force a simple password in minutes. Above all, make sure you REMEMBER the new password.
If you change the device unlock password/PIN, the encryption password will be automatically changed as well. You need to use this tool again to change it back, if required.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.

User's Reivew
5 ★Awesome.
5 ★Exactly what I needed
5 ★I've used this app on CyanogenMod 11 (Android 4.4). Unfortunately, the latest version doesn't work on OnePlus One with HW encryption. It says "pw correct, but data corrupted". To answer the author: Sorry, that pw change dialog does not exist on CM12 Nightly 0118 for N4, N7, OPO.
5 ★For a long time, I used EncPassChanger - it no longer works with Lollipop, and hasn't been updated since 2012. Found this app, and it works to separate my (strong) encryption-password from my (convenient) unlock-PIN.
5 ★This utility makes it possible to drastically improve the security of your (rooted) Android devices. I was thrilled to see it become available for Lollipop, and can attest that it performs its job beautifully.
5 ★This program works perfectly on my Nexus 5 running CyanogenMod 11. Having a strong boot password protects against cold boot / offline attacks, but lets me use a basic PIN on the lockscreen for normal use!
5 ★using cm12, is super su still required? i used it initially - but i'm tempted to try without it as uninstalling super su is easier said than done, and i'd prefer to use the built in root managment....
5 ★I've tried any manner of order-of-operations to de-couple my Encryption password from my Screen lock PIN on my Moto E 2015 (2nd gen) running Lollipop and I just cannot get it to work. Nothing against the app. I've read Nikolay's page about Android L encryption which seems to say that different Password/PIN combos are possible. But after running Cryptfs Password (or using the command-line instruction 'sudo vdc cryptfs changepw "newpassword") I get the following message: "Decryption Unsuccessful. The password you entered is correct, but unfortunately your data is corrupt. To resume using your phone, you need to perform a factory reset..." I guess I will have to wait until CyanogenMod is released for this phone...
5 ★This is a great little app for those who want their encryption password to be different from their lock screen password, especially if you use a pin number. It's nice and simple.
5 ★Works as described. Now the phone encryption password can be as long as you wish. Thanks Nikolay, keep up the good work!
1 ★Ok, I need support.. I change password, and it decrypts in TWRP. But it doesn't from regular boot procedure. Android 5.0.1/Nexus 4
5 ★Tried on Nexus 7 (2013) with android 5.0.1
