Encrypt and decrypt files on Android devices with the Decrypto . app

With so much leaked information today shows that a hacker problem is ready to attack and exploit information from your electronic device even if you use it with different types of operating systems. That’s why we need to encrypt directory files as well as decrypt directory files when necessary.

If you encrypt your SD card using an OEM-provided feature on your smartphone, like on Samsung Galaxy devices, you can still access the photos or music stored on the card through any gallery or app. use any music as long as the SD card is in the same device. However, encrypting specific files requires the use of third-party applications, and this hides those files. That means you won’t be able to view those photos or videos on any other app than the encryption app.

Now that you know what you’re getting into, let’s get to it. We will use an app called Hide Files – Decrypto uses AES 256-bit military-grade encryption to securely protect your files. So the first thing you have to do is install the app from the Google Play store.

Encrypt and Decrypt Files on Android with Decrypto

  1. Launch the app and press Sign me up . Enter your name, email address, and password just like any other sign-up you’ve ever done. Press Registration when completed.
  2. You will then be asked to enter pin code or sample . You can choose keep using your password but since your password is probably something pretty long you might not want to type it in every time you want to access your encrypted files.
  3. Press button brings up several options. Select the file type you want to encrypt and hide.
  4. Select the image just like you would on any other app. The application also supports long press and then drag to select multiple photos. Click the tick mark on the top of the page when you have selected the files you want to encrypt. Press the buttonbutton to confirm your selection.
  5. You will be shown some information about the files, tap again and the application will start encrypting the files. Encryption is pretty fast but it can take a while depending on the size and number of files you choose.
  6. Your encrypted files are neatly organized into different tabs that you can scroll through by swiping left and right. There are many different sorting options as well. Next time you open the app, it will ask for the PIN, pattern or password you entered. You can also encrypt a file directly from the application you are viewing using the option Share .
  7. Decryption a file is even easier. Just press and hold the file to select it, select multiple files if you want and just tap the icon lock up at the top right. Confirm by selecting YES and the selected files will be decrypted, resetting to their original location on your phone.

The app even lets you create different vaults to organize your files from Settings -> Vault. There are also quite a few options in the settings if you want to explore including Theme Manager allows you to completely change the look and feel of the application. This is a welcome feature as you can spend a lot of time on the app if you use it extensively. There is also the option cloud sync, as the name suggests syncs your encrypted files to the cloud so you can then access them with any device but it’s a paid feature. You can upgrade to the pro version for just $3.7.

Overall, we really like this app. The UI is pretty awesome and the app itself guides you through every step, the animations are really cool. But what’s a great app when it can’t function right? Fortunately, that is not the case here. We tested version 3.2 belong to Decrypto for almost a day and it worked as expected. There is one key feature that we could not find and that is the option to choose storage. This means that whatever you encrypt is stored on your phone’s internal memory, and this can fill up space pretty quickly. Other than that, it’s a really neat, well-polished app aimed at the average user while still packing some advanced features.
