Documentation

Overview

Binary `verifier` checks the inclusion of a particular Pixel Factory Image, identified by its build_fingerprint and vbmeta_digest (the payload), in the Transparency Log.

Inputs to the tool are:

• the log leaf index of the image of interest, from the Pixel Binary Transparency Log, see: https://developers.google.com/android/binary_transparency/image_info.txt
• the path to a file containing the payload, see this page for instructions https://developers.google.com/android/binary_transparency/pixel#construct-the-payload-for-verification.
• the log's base URL, if different from the default provided.

Outputs:

• "OK" if the image is included in the log,
• "FAILURE" if it isn't.

Usage: See README.md. For more details on inclusion proofs, see: https://developers.google.com/android/binary_transparency/pixel#verifying-image-inclusion-inclusion-proof
