I use a FIDO android SDK https://developers.google.com/android/reference/com/google/android/gms/fido/package-summary and web FIDO lib https://github.com/lbuchs/WebAuthn as a server
To complete authentication I send to the server the following payload:
{"authenticatorData":"uGLTOEtQtBsB4wjhEvR0ZVayRWn/3mhUyp6dqFFY0a8BAAABDQ==","clientDataJSON":"eyJ0eXBlIjoid2ViYXV0aG4uZ2V0IiwiY2hhbGxlbmdlIjoiLW9zc3JiYXY3SmhmUWlQY1ZlMzFkdDQxMG5ZWHVvWW9kM1FYdHc5VmlIUSIsIm9yaWdpbiI6ImFuZHJvaWQ6YXBrLWtleS1oYXNoOmZiRU5UdkNTZVItQXdKVjVycnJCc2I5OHAtakV3MGM1U1NPTXVsX0t3YUkiLCJhbmRyb2lkUGFja2FnZU5hbWUiOiJjb20uYWZ0ZXJsb2dpYy5hdXJvcmEubWFpbCIsInRva2VuQmluZGluZyI6eyJzdGF0dXMiOiJwcmVzZW50IiwiaWQiOiJodHRwczpcL1wvdGVzdC5hZnRlcmxvZ2ljLmNvbSJ9fQ==","id":"LEBlQOlamqsmKzRBPQe9y0BFN5IaQ5BBB1ByiDH85HulzCYQTffqeK0RQDoZqUO7syGZY+hkfWf9P2FiQQ3eVA==","signature":"MEUCICFf8qFGiXxGTBokpstfUsCwbd7JTsLlDrFZoGMi3tZzAiEA0zAXxFDeqA7gF6YahudK+LD2gDUPtAnXqgAvvhVc/vE="}
The field clientDataJSON contains a base64-encrypted JSON object that has property "origin":"android:apk-key-hash:fbENTvCSeR-AwJV5rrrBsb98p-jEw0c5SSOMul_KwaI"
But the server responds with an error "invalid origin".
At the same time, my web FIDO auth implementation sends clientDataJSON with "origin":"https://test.afterlogic.com" and everything is working fine in this case.
How I can verify origin with android:apk-key-hash on the webserver? I will be appreciated any other ideas on how to deal with this.
