GrapheneOS/platform_bionic

GrapheneOS

There are no reviews yet. Be the first to send feedback to the community and the maintainers!

Hardened Android standard C library. Some of the past hardening has not yet been ported from Marshmallow, Nougat and Oreo to this Android Pie repository. Most is available via archived tags in https://github.com/AndroidHardeningArchive/platform_bionic (check both the most recent Oreo and Nougat tags).

hardened_malloc

Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain more portability / integration over time.

Camera

Modern camera app focused on privacy and security with QR & barcode scanning.

Vanadium

Privacy and security enhanced releases of Chromium for GrapheneOS. Vanadium provides the WebView and standard user-facing browser on GrapheneOS. It depends on hardening in other GrapheneOS repositories and doesn't include patches not relevant to the build targets used on GrapheneOS.

PdfViewer

Simple Android PDF viewer based on pdf.js and content providers. The app doesn't require any permissions. The PDF stream is fed into the sandboxed WebView without giving it access to content or files. CSP is used to enforce that the JavaScript and styling properties within the WebView are entirely static.

Auditor

Hardware-based attestation / intrusion detection app for Android devices. 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.

grapheneos.org

Main website servers

linux-hardened

Minimal supplement to upstream Kernel Self Protection Project changes. Features already provided by SELinux + Yama and archs other than multiarch arm64 / x86_64 aren't in scope. Only tags have stable history. Shared IRC channel with KSPP: irc.freenode.net ##linux-hardened. Currently maintained at https://github.com/anthraxx/linux-hardened.

os-issue-tracker

Issue tracker for GrapheneOS Android Open Source Project hardening work. Standalone projects like Auditor, AttestationServer and hardened_malloc have their own dedicated trackers.

platform_manifest

Repo manifest for the GrapheneOS mobile privacy and security hardening project.

AppStore

AttestationServer

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.

tls-pinning

Utilities for setting up TLS key pinning for Android app network security configuration. We pin the keys of trusted roots and backup keys in order to avoid needing to rotate the pinned keys. Backup keys are never intended to be used unless the roots stop being available and then only need to be used until the pins expire or get updated.
