Detailed Description

Cryptnox secure channel protocol over NFC.

Declares CW_SecureChannel, responsible for every low-level APDU exchange required to establish and use an authenticated, encrypted session with a Cryptnox Hardware Wallet:

• SELECT AID
• Manufacturer + card certificate retrieval and chain verification
• Ephemeral key extraction and ECDH session key derivation
• MUTUALLY AUTHENTICATE
• AES-CBC + MAC secure messaging (encrypt / decrypt / SW check)

The class is composed inside CryptnoxWallet and is not normally used directly by application code.
