Encryption is the process of encoding all user data on a device using symmetric encryption keys. Once a device is encrypted:
all user-created data is automatically encrypted before committing it to disk
all reads automatically decrypt data before returning it to the calling process
Encryption ensures that even if an unauthorized party tries to access the data, they won’t be able to read it.
Digi Embedded for Android 11.0 supports file-based encryption (FBE). File-based encryption allows different files to be encrypted with different keys that can be unlocked independently.
