Reference implementation of SLIP-0039: Shamir's Secret-Sharing for Mnemonic Codes
This SLIP describes a standard and interoperable implementation of Shamir's secret sharing (SSS). SSS splits a secret into unique parts which can be distributed among participants, and requires a specified minimum number of parts to be supplied in order to reconstruct the original secret. Knowledge of fewer than the required number of parts does not leak information about the secret.
See https://github.com/satoshilabs/slips/blob/master/slip-0039.md for full specification.
With pip from GitHub:
$ pip3 install https://github.com/trezor/python-shamir-mnemonicFrom local checkout for development:
$ python3 setup.py developCLI tool is included as a reference and UX testbed. It is very obviously insecure. DO NOT USE it for generating or decoding any sort of serious secrets.
When the shamir_mnemonic package is installed, you can use the shamir command:
$ shamir create 3of5 # create a 3-of-5 set of sharesUse shamir --help or shamir <command> --help to get detailed help.
If you want to run the CLI from a local checkout without installing, use the following command:
$ python3 -m shamir_mnemonic.cli
