  1. See flexsecure-applets/docs/2-hardware.md at master · DangerousThings/flexsecure-applets · GitHub

  2. Yes, the Apex can even do JC 3.0.5. secp256r1 is supported, you just have to specify the curve coefficients manually similar to e.g. status-keycard/src/main/java/im/status/keycard/SECP256k1.java at master · keycard-tech/status-keycard · GitHub .

  3. At least 133 bytes, possibly more, I am not quite sure.

  4. Correct, Fidesmo controls the ISD keys on the Apex. The flexSecure is the same chip but without Fidesmo, meant for developers and power users. You have to ask Fidesmo for a developer account if you want them to sign your applets to load them on Fidesmo-enabled devices.

  5. The Source of the Apex FIDO2 applet is currently private. The applet binary is available via Fidesmo for Apex customers.

  6. Thats a question for @amal

I think your applet presents an interesting opportunity for collaboration. It would be great to get you in contact with @amal .
