python-keepkey

Client side implementation for KeepKey-compatible Bitcoin hardware wallets.

This is a modified version of python-trezor. The changes made were to support KeepKey's protocol, as well as the additional feature set of KeepKey. For example, by default, device_recovery command invokes KeepKey's style of device recovery using the Recovery Cipher.

See http://www.keepkey.com for more information.

Example

also found in helloworld.py

.. code:: python

#!/usr/bin/env python

from keepkeylib.client import KeepKeyClient from keepkeylib.transport_hid import HidTransport

def main():

  # List all connected KeepKeys on USB
  devices = HidTransport.enumerate()

  # Check whether we found any
  if len(devices) == 0:
      print('No KeepKey found')
      return

  # Use first connected device
  transport = HidTransport(devices[0])

  # Creates object for manipulating KeepKey
  client = KeepKeyClient(transport)

  # Print out KeepKey's features and settings
  print(client.features)

  # Get the first address of first BIP44 account
  # (should be the same address as shown in KeepKey wallet Chrome extension)
  bip32_path = client.expand_path("44'/0'/0'/0/0")
  address = client.get_address('Bitcoin', bip32_path)
  print('Bitcoin address:', address)

  client.close()

if name == 'main': main()

PIN Entering

When you are asked for PIN, you have to enter scrambled PIN. Follow the numbers shown on KeepKey display and enter the their positions using the numeric keyboard mapping:

=== === === 7 8 9 4 5 6 1 2 3 === === ===

Example: your PIN is 1234 and KeepKey is displaying the following:

=== === === 2 8 3 5 4 6 7 9 1 === === ===

You have to enter: 3795

Running Tests

To run unit tests that don't require a device:

.. code:: shell

$ python tests/unit/*.py

Release Process

  • Check that the testsuite runs cleanly
  • Bump the version in setup.py
  • Tag the release
  • Build the release
    • sudo python3 setup.py sdist bdist_wheel bdist_egg
  • Upload the release
    • sudo python3 -m twine upload dist/* -s --sign-with gpg2

KeepKey Bridge

The KeepKey Bridge is a standalone TCP-to-webusb bridge the KeepKey. It runs a python-keepkey client based process that allows a localhost-based process to communicate with the KeepKey wallet, thus bypassing the need for a webusb connection from a browser based platform.

The KeepKey Bridge is recommended only for advanced users who have problems connecting the KeepKey on Windows.

Running the KeepKey Bridge

Download the KeepKey Bridge installer kkbsetup.exe for Windows in the release package here:

https://github.com/keepkey/python-keepkey/releases

When running the KeepKey Bridge, a blank cmd window with the title "KepKey Bridge" will be visible. To stop the bridge, simply close the cmd window.

Build for Windows

Requirements:

  • Windows 10
  • python3
  • waitress (python package)
  • py2exe
  • Inno Setup Compiler (optional, for creating Windows install exe)

From a command prompt terminal window, run python wbsetup.py py2exe -d windows/dist

This will create a windows\dist folder with the Windows stand-alone executable file wait-serv.exe

Inno Setup Compiler

This tool builds and packages the executable for install on Windows. Build with the provided installer script (modify version, etc., as needed)

``windows/KeepKeyBridge.iss``

This will produce an executable install app

``windows/Output/kkbsetup.exe``
