FirmwareKit.AVB

A C# implementation of Android Verified Boot (AVB) library, supporting parsing and verification of VBMeta images and Android footprints.

Features

  • Parse VBMeta headers and images.
  • Support for AVB descriptors and footers.
  • Hardware-independent I/O interface via IAvbOps.
  • Managed libavb_ab flow and boot-control facade via AvbAbFlow and AvbBootControl.
  • Managed libavb_user equivalent helpers via AvbUser (verification/verity toggles).
  • Managed libavb_cert equivalent validation via AvbCertValidator and IAvbCertOps.
  • Multi-framework support: net8.0, net10.0.
