A is a sensitive attestation document that contains a unique set of cryptographic keys (RSA and ECDSA) and a certificate chain signed by a Root Certificate Authority (CA).

The device_ID must match the ID in the XML file.

A valid keybox.xml typically follows a structured XML format including: : Encoded ECDSA and RSA master secrets. A is a sensitive attestation document that contains

Creating a fresh keybox.xml file, often for development or testing purposes (using tools like AOSPGenKeyBox ).

: Typically ECDSA (Elliptic Curve Digital Signature Algorithm) for modern Play Integrity bypasses. For developers and tinkerers

If you’re getting attestation failed 0x3A after an OTA update, this is probably why.

PSA: The "new" KeyboxXML format is here – don't get caught with invalid attestation

For the average user, this means fewer hacked streaming credentials and more reliable app security. For developers and tinkerers, it means learning a new specification—but one that ultimately creates a more trustworthy Android ecosystem.
