How To Decrypt Files From Android/usb

Encrypt & Hide Files, Photos, & Videos on Your Android [How-To]

Hello,

I have my personal Android phone with SD card, and enabled option to connect to PC as USB stick. I often plug my phone to my work PC where some McAfee security software was installed recently. I say “some” because I don’t know exactly software name, there are so many McAfee packages, that I am completely lost in them . All I know is that software somehow encrypted my files on Android phone, so now every file extension is ended with ” *” and in the header of each file I see “Type: This file was ecnrypted with McAfee Endpoint Ecryption for Files and Folders – If you see this message you must not edit or save this file, doing so will irretrievably corrupt the file… Version 3.0.0, KeyUid…, ProviderId: McAfee ePO”

The files are not accesible, I can’t open photos, play mp3s and so on, simple rename on extension doesn’t help. So my question is how to deal with that situation? Is it possible to decrypt files at home, or should I use my work PC? What are the steps to decrypt/recover them? And how to avoid such situation in future?

Thank you.

Encryption Changes In Android 70

This problem was solved with Android 7.0 , which changed the encryption process to a file-based one and introduced direct boot, allowing certain apps to operate in a limited capacity, even without signing into the device with your password or PIN. The new file-based encryption also upped the key size to AES 256-bit, greatly improving security.

With either method, encryption is one-way, which means that once youve completed the process and encrypted your device, theres no way to turn it off again without performing a complete factory reset on the encrypted device.

Furthermore, you may experience a slight hit to performance especially if your device is old as all the files on your phone must be decrypted in real time as you attempt to access them. However, for newer and more powerful devices, this should barely be noticeable, as they should be more than capable of performing the extra computations.

If your device is rooted meaning youve gained full admin access to the Android subsystems it cant be encrypted straight away. Rather, youll first have to unroot your device and then enable encryption before subsequently rooting it again.

This is incredibly important to bear in mind, as attempting to encrypt a rooted device can have catastrophic consequences for any data you havent backed up.

Is My Device Already Encrypted

Encryption has been an optional part of the Android operating system since Gingerbread 2.3. After Lollipop 5.0, some phones had the feature turned on right out of the box. After Marshmallow 6.0 was released, many devices made encryption mandatory. Despite these measures, however, only about 10% of Android devices are fully encrypted. That leaves a lot of unprotected phones out in the wild.

If your phone or tablet is new and already has Android 6.0 or better, chances are the entire disk was encrypted before you even turned it on. To verify, simply go to Settings > Security and scroll down to the section that says Encrypt phone or Encrypt tablet. If encryption was already active, the text should say Encrypted.

What Happens When You Encrypt Your Phone

How TO Encrypt Or Decrypt Files On Android

In basic terms, encryption is a process that uses a key to scramble a users data, making it unreadable to anyone without the key to unscramble it again.

Obviously theres a lot more to it behind the scenes, with different forms of encryption performing the intended task in different ways. For a more in-depth look at encryption technology, in general, check out our description of encryption.

Devices running Android 6.0.1 and earlier use full-disk encryption based on dm-crypt and are protected by an AES 128-bit key. Because nothing on the disk can be read without authentication, no apps will be able to perform their tasks if your device has rebooted and you havent yet entered your password.

For the most part, this isnt a huge problem. However, in the case of an unexpected reboot, some apps, such as alarms and reminders, will not go off until users authenticate themselves.

A Simple Guide To Encrypt Files Programmatically In Android Devices

When it comes to storing files in android , developer should first identity the sensitivity of the file verses where to store that particular file.Android devices has two storage partitions as Internal Storage and External Storage

These names come from the early days of Android, when most devices offered built-in non-volatile memory , plus a removable storage medium such as a micro SD card . Many devices now divide the permanent storage space into separate internal and external partitions. So even without a removable storage medium, these two storage spaces always exist, and the API behavior is the same regardless of whether the external storage is removable.

Next big question is , what is the difference between these storage partitions.

Internal storage: Files saved here are accessible by only your app.neither the user nor other apps can access your files

External storage: Files saved here may be read outside of your control.

So if file datais sensitive save it in Internal Storage or else, external storage.

In rooted devices, all your internal storage can be exposed as users and other apps with root permissions can access these files directly.For the testing purposes Ive tried AES and Blowfish Algorithms, seems that Blowfish Algorithm is little faster ! checkout the following code to encrypt/decrypt files in external storage.

Happy Coding !

Is It Safe To Encrypt My Android Device

It is generally safe to encrypt your Android devices. For the older device models, encrypting your Android can result in a drop in system performance. However, this performance drop becomes unnoticeable in the newer Android models. Also, it is worth mentioning that the encryption process is irreversible. Once performed, it can only be removed by a complete factory reset of the device.

What Is Encryption

How TO Encrypt Or Decrypt Files On Android

The idea is to protect your data from falling into the wrong hands, should someone get ahold of a mobile device. Full disk encryption encrypts all the data on your storage device.

Full disk encryption is basically encryption on a hardware level. It automatically converts data on a hard drive into something that cant be deciphered without the key. Without the right authentication key, the data is inaccessible, even if a hard drive is removed and placed in another machine.

Whats nice about FDE is its automatic, so it requires no special action from the user other than providing a key. As data is written, its automatically encrypted, and as its read, its automatically decrypted.

Mobile devices like smartphones and tablets have encryption options that will also provide protection of storage. In this case, its not typically a disk but is still just storage thats encrypted and accessed using some key. Its usually just a matter of enabling the appropriate options and an extra step to provide a key.

Why Use A Zip File

There are several reasons to want to use a Zip archive versus just storing the files in a folder, but what they all have in common is ease of use.

Zip files organize data into one single folder that acts just like a file, meaning that you can store hundreds of files and folders in one location without fear that you might accidentally delete some of the content. This is common for file backups.

You can also share Zip files online to send someone multiple files simultaneously. The alternative is to share several emails, one after the other, with attachments strung all over the place. This is usually hard to deal with as a recipient and definitely unprofessional.

A Zip file can be compressed too to save disk space, which is something you should think about if youre planning on encrypting a ZIP file that has lots of items in it, or one that contains sensitive files.

Tip: Encrypting ZIP files is limited to just those files. Learn how to encrypt your entire hard drive for even more protection.

What Type Of Encryption Should I Get

There are many different types of encryption software and tools. Some come with other security elements included. Many computers and software already come with options like full disk encryption. But the problem is this software is usually available on most devices, but many businesses dont realize it hasnt been implemented. Fortunately, its fairly easy to activate encryption on devices.

Check if your current software offers storage encryption. If not, there are plenty of tools that offer encryption.
