How to tell original from fake DS18B20 temperature sensors.

Hardware-based attestation and intrusion detection app for Android. It provides both local verification with another Android device via QR codes and optional scheduled server-based verification with support for alert emails. It uses hardware-backed keys and attestation support as the foundation and chains trust to the app for software checks.

[Feature complete] SHA-3 and Keccak checksum utility

attestation.app remote attestation server. Server code for use with the Auditor app: https://github.com/GrapheneOS/Auditor. It provides two services: submission of attestation data samples and a remote attestation implementation with email alerts to go along with the local implementation based on QR code scanning in the app.

[Basically feature complete] Keccak-family hashing library

Python implementation of C2PA: Coalition for Content Provenance and Authenticity.

A small subset of the submitted sample data from https://github.com/GrapheneOS/Auditor. It has a sample attestation certificate chain per device model (ro.product.model) along with a subset of the system properties from the sample as supplementary information.

Digitally signs and verifies files using RSA and SHA-256 to ensure file authenticity, integrity, and tamper detection.

Auditor app prebuilt using the latest official release of the Auditor app.
