Encrypt and Decrypt Files on Android

It doesn’t matter how tight your phone’s security is; if it’s stolen, it’s of no use. What’s worst is that the person who stole your smartphone can access the data you’ve stored in it. While it’s pretty easy to erase or lock the device from Google’s Find my Device, it’s always best to encrypt the files.

When you encrypt files on Android, the files will be unreadable. This means that even if your phone is stolen, the files stored in it would be unreadable as long as they are not decrypted with an actual key.

You can use the built-in encryption tool of Android to encrypt your files, but it isn’t very easy and takes loads of time. Also, it will encrypt all your files, not the selected ones. Hence, this article will share an easy guide on encrypting specific files on Android devices.
