This simple tool can be used to sign a proposed multisig transaction (P2SH spend). You must already possess the associated extended public key (BIP32 wallet). The details of the transaction to be signed can either be fetched from Coinkite (based on a very long URL, provided with --url argument) or in a file, as downloaded from the site.

The signed output (which is a small JSON file) can be uploaded manually, but this program will by default upload the file to Coinkite. If this new signature is the final one required, the transaction is sent immediately.

This code is functionally equivalent to the standard Javascript offline-signing code we provide at: https://coinkite.com/offline/

Save the file you get from pressing beside the Green arrow, and provide that as the --proposal argument. If you need to manually upload, use the file saved with --output at the Blue arrow.

You must always provide a base58 encoded xprv key using the --key argument.

Usage: olsign.py [OPTIONS]

Options:
  -i, --proposal FILENAME  JSON file downloaded from CK already
  -u, --url URL            https://coinkite.com/co-sign/json/<req>:<cos>:<pin_check>
  --html / --no-html       Show details of proposed transaction?
  -k, --key FILENAME       Extended private key (base58)  [required]
  --upload / --no-upload   Auto upload signed results file to CK?
  -o, --output FILENAME    Write signed response to this file
  --help                   Show this message and exit.

See also the version numbers in the requirements.txt file, which should be ready to use with pip install -r requirements.txt.
