Recent developments in the community have introduced several tools to manage and spoof these keys: 5ec1cff/TrickyStore - GitHub
Depending on your device generation and requirements, here is how to approach keybox management:
The landscape for generating keybox.xml files has seen significant new developments in 2024 and 2025. Several projects now make it easier than ever to create these attestation files. keyboxxml new
Place the file in the designated directory, such as /data/adb/tricky_store/keybox.xml . Target: Define app targets in target.txt if needed.

Several tools leverage these cryptographic keys to restore "Device" and "Strong" Play Integrity: 1. TrickyStore
At its core, keybox.xml is an XML file that contains a device's attestation identity — essentially a digital passport that proves a device is genuine and secure. It typically resides in protected directories like /data/misc/keystore/ or /mnt/vendor/keystore/ and is used by Android's Keymaster and KeyMint systems to generate cryptographic proofs for apps. Target: Define app targets in target
RKP represents a fundamental shift away from the keybox.xml model. Instead of relying on manufacturer-provisioned keys stored in XML files, devices can obtain fresh attestation keys on demand from Google's servers. This eliminates the need for vulnerable pre-provisioned keyboxes and makes attestation more resilient to bootloader unlocking.
