How to encrypt & decrypt files, videos, pictures in Android with a few taps

From those beautiful beach selfies to email attachments, our smartphones is the sweet home for all our small and big personal details, and everything else that we love and want to enjoy, while on the go. But we all have that creepy secret hunter friend who will not leave a single chance to get access to our smartphones and try out exploring everything that we don’t want them to see. Though we can still stop our friends from accessing those private things on your smartphones by simply not handing our phone over to them, it is not equally easy to stop different apps and online services from accessing the files and other private data on our smartphones.

Whatever the case may be, it will really be useful if we can encrypt the files and folders on our Android device to completely stop that creepy friend from accessing those private photos and beach selfies or prevent other services from accessing them. You just need a single app and keep all your files encrypted and safe on your smartphone. Once the items are encrypted, they will no longer be visible in other apps like Gallery, Photos, any video player or anywhere else. It means you can enjoy complete privacy if you follow the method to encrypt your files and other items on your Android device.

Step 3: Now type the password with which you want to encrypt the item(s) in the two boxes and tap on ‘Encrypt’. The encrypted item(s) will now be available in the same location as the source.

In this process, the source item(s) will also be preserved without any kind of encryption. New items with padlock icons will contain the encrypted files as shown in the screenshot below.

You can even choose the option to delete the source items before starting the encryption process.

If your smartphone has a fingerprint sensor, you can even use it to encrypt the contents. But you will still need a password.

If you visit the same location from a different file manager, the items will be present as files and folders with the extension ‘.sec’, probably to signify ‘Secure’.

You can open the items anytime by typing the password. As the items are encrypted, you will not be able to open them by connecting your smartphone to PC or from any other file manager. If it is a folder, the encrypted folder will contain all gibberish unless you decrypt it with your password.

Even though the files are encrypted, they can still be deleted by any file manager, or by connection your smartphone to the computer.

*If you are planning to uninstall Solid Explorer File Manager from your Android for any reason, decrypt the encrypted files and then proceed with the uninstallation, else you might lose the encrypted files forever.
