| |
Tested on hardware with an ATECC608B at 0x60. The device binds successfully, passes the driver's sanity check, and registers the ecdh-nist-p256 KPP algorithm.
The hardware ECDH path was also exercised using a minimal KPP test module, covering private key generation, public key derivation, and shared secret computation.
