Android Key Attestation Sample

This sample illustrates how to use the Bouncy Castle ASN.1 parser to extract information from an Android attestation data structure to verify that a key pair has been generated in an Android device.

This repository contains a server sample that shows how to attest an Android certificate outside the Android framework. This is the recommended best practise, as it is safer to check the certificate's authenticity on a separate server that you trust.

For more details, see the documentation and the guide at .

Getting Started

See the server sample for details.
