Part 4. Two Types of Encryptions Used on Android Devices

Android devices offer two primary types of device encryptions: file-based encryption and full disk encryption. Both methods are used to secure data on your device, but they operate differently and have their own unique advantages and disadvantages.

File-based encryption

File-based encryption (FBE), as the name suggests, works by encrypting individual files and directories on your device. This means that each file and directory is encrypted with its own unique key, providing an additional layer of security.

Starting from Android 7.0 (Nougat), file-based encryption became available as the default encryption method for Android 10 and later versions. This encryption method is useful for devices that store a lot of sensitive data, such as smartphones used for business purposes. In addition, file-based encryption allows users to share files without revealing their content to unauthorized parties.

Full-disk encryption

In contrast, full-disk encryption (FDE) encrypts everything on your device, including the operating system and user data. Although it provides a higher level of security than file-based encryption, it can also be resource-intensive and may impact the device's performance.

Full-disk encryption was first introduced in Android 5.0 (Lollipop) and is still widely used today. It is particularly useful for devices that store extremely sensitive information, such as government or military smartphones, where maximum security is crucial.

How to choose the one best suited for your needs?

Your choice of encryption should depend on your specific needs and use case. If you only need to encrypt certain files or folders, file-based encryption would be a better choice. However, if you prioritize maximum security and do not mind the performance trade-offs, full-disk encryption may be the better option. Ultimately, you should make your decision based on your specific requirements and use case.
