Key Attestation Demo is an application that showcases the key attestation feature available on modern Android devices. It enables applications to verify the security of cryptographic keys stored within the device's hardware-backed keystore. This app helps developers and security enthusiasts understand the workings of key attestation and how it can improve application security.

The demo utilizes Android's hardware-backed keystore security features, designed to safeguard cryptographic keys from unauthorized access. The application itself does not store sensitive data but demonstrates the device's security mechanisms. Users should keep their devices updated with the latest security patches for optimal security.

This application requires only minimal permissions, mainly to access the device's keystore functionalities necessary for demonstrating key attestation. It does not request sensitive permissions like contacts or location, making it a low-risk app to install and use.

Although mainly aimed at developers and security professionals, it can also benefit tech-savvy users interested in understanding Android security. The app offers an educational experience about how cryptographic keys are secured on Android devices, providing value even to non-developers with a strong interest in mobile security.

The app is available on the Google Play Store. Users can find and install it by searching for its name. Ensure your device runs Android 7.0 or higher for proper installation and operation.
