About this app

The hardware security implementation varies wildly across Android manufacturers. This little utility app, primarily aimed at developers, displays the secure storage capabilities of the device, namely Trusted Execution Environment (TEE) and StrongBox. It also displays the certificate chain highlighting the presence of a valid root certificate issued by Google (Root of Trust), which is useful for key attestation.

Without actually generating test keys it is not possible to fully assess whether a device supports for example different algorithms so the app does that for you!

These capabilities are rarely listed in spec sheets of devices so you need this tool to assess devices.
Verify TEE and StrongBox support by generating real hardware-backed keys.

Data safety

Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
