How to Encrypt/Password Protect Files on Android

We have seen how you can hide your photos and videos on Android. We have also discussed how one can lock an app and secure messages using a password. But what about individual files saved on our SD Card? What if someone wants to lock a PDF, a document or any other file that he wants to hide using a password?
Today we will talk about a simple tool for Android called File Locker, using which you can easily lock any file using a password and secure the access to it. So let’s see how the app works.

Locking the Files

Step 1: Download and install File Locker on your device from the Play Store to get started. The app works on all the devices running on Android 2.1 and above.
Step 2: After you install the application, launch it. The app will look like a simple file manager and will display all the files and folders on your Android. To lock a file, browse for it and long tap on it to open a popup menu.

Step 3: In the popup menu, select the option Lock. You can even batch select files and lock them at once. After you select the lock file option the app will ask you for the password you use to encrypt your files, after providing which it will hash the contents of your files.

Note: The app does not provide a master password option and asks for a new password every time you try to lock a file. As a word of advice I would recommend you use the same password all the time to keep things a little simple.
After the file’s been locked, it cannot be read using any app installed on your device or even a computer. Let’s now see how to unlock the files.

Unlocking the Files

Open the Locked tab to see all the files you have locked using the app. To unlock a file, simply tap on the lock icon next to the file and provide the password. Put a check against the option if you want to be locked automatically when you exit the app.
