Questions About Attestation Certificate

Is there a standard process for obtaining or generating the attestation certificate?
Just get in to Java Cards, mainly want use it for login to windows lol

Demos are having trouble working with the applet

I've successfully managed to install the applet on a JC 3.0.4 card from Idemia (Oberthur), following GP spec 2.2.1. The attestation certificate was used from the README examples.

The proprietary dependencies were swapped as follows:

1. KeyBuidlerX.TYPE_AES_STATIC -> KeyBuilder.TYPE_AES
2. KeyAgreementX.ALG_EC_SVDP_DH_PLAIN_XY -> KeyAgreement.ALG_EC_SVDP_DH_PLAIN

http://u2fdemo.appspot.com can register the authenticator, but testing fails.
https://demo.yubico.com/u2f is not capable of registering at all.

Do you have any ideas for what I might be doing wrong?

Unable to install CAP file

I'm getting an error 6A 88, though it may be related to the card.

Card is a sm@rtcafe 6.0 80k.

Provide a cap file

So that it could be loaded to cards!

readme.md: dependencies and OS version

Hi Tobias
I would like to experiment with a FIDO U2F card without being a real programmer. Can you explain a little further where to get/buy the dependencies com.nxp.id.jcopx.KeyAgreementX and com.nxp.id.jcopx.KeyBuilderX? If they are included in newer Javacards, how do I determine the version and how do I get it from the card to the project? Any chance to get a binary?
