Conceal is a Facebook library providing Java APIs for fast, memory-efficient encryption and authentication of data on Android, especially large files on disk. It uses sane cryptographic defaults rather than exposing algorithm choices, and is optimized for older, low-memory Android devices.
Use cases
- encrypt large files on android devices
- fast encryption on old android phones
- securely store data on disk in an android app
- encrypt files with low memory usage
- add encryption to an android app without choosing crypto algorithms
When to choose
- you need to encrypt large files on older or low-memory Android devices
- you want simple, opinionated encryption defaults instead of configuring algorithms yourself
When to avoid
- you need a general-purpose crypto library with algorithm flexibility
- you target modern Android versions where the system crypto stack performs comparably
- you need an actively maintained library - the project is archived with no recent releases
