CLI for managing Cryptnox Hardware Wallet smart cards

cryptnox-cli is a command-line interface for managing Cryptnox Hardware Wallet smart cards, enabling secure seed initialization and cryptographic signing for Bitcoin and Ethereum.

Works with Cryptnox Hardware Wallet smart cards running firmware v1.6.0 or later.

Works with Cryptnox readers and any other standard PC/SC smart card reader:

pip install cryptnox-cli

mstore install cryptnox-cli

Visit the MStore page to install cryptnox-cli via the graphical user interface.

git clone https://github.com/cryptnox/cryptnox-cli.git
cd cryptnox-cli
pip install .

This installs the package and makes the cryptnox command available (if your Python installation is in your system PATH).

1. Create or obtain a raw unsigned transaction externally.
2. Run the signing & send command:
   cryptnox btc send <recipient_address> <amount> [-f <fees>]

1. Factory reset each card:
   cryptnox reset → enter PUK → verify reset.

2. Initialize each card:
   cryptnox init → (optional) set name/email → set PIN (4–9 digits) → set or generate PUK → verify init.

3. Run dual seed procedure:
   cryptnox seed dual — follow prompts: insert Card A (enter PIN), swap to Card B (enter PIN), swap back as requested.

1. Run command: cryptnox change_pin
2. Enter current PIN → enter new PIN → verify change.
3. Check with cryptnox info using new PIN (BTC & ETH accounts displayed).

1. Run command: cryptnox get_xpub
2. Enter PIN → enter PUK
3. The card returns the xpub
