Implementation of Bitcoin BIP-0039
Project description

Reference implementation of BIP-0039: Mnemonic code for generating deterministic keys
Abstract
This BIP describes the implementation of a mnemonic code or mnemonic sentence – a group of easy to remember words – for the generation of deterministic wallets.
It consists of two parts: generating the mnenomic, and converting it into a binary seed. This seed can be later used to generate deterministic wallets using BIP-0032 or similar methods.

Installation
To install this library and its dependencies use:
pip install mnemonic
Usage examples
Import library into python project via:
from mnemonic import Mnemonic
Initialize class instance, picking from available dictionaries:
english
chinese_simplified
chinese_traditional
french
italian
japanese
korean
spanish
mnemo = Mnemonic(language)
mnemo = Mnemonic("english")
Generate word list given the strength (128 - 256):
words = mnemo.generate(strength=256)
Given the word list and custom passphrase (empty in example), generate seed:
seed = mnemo.to_seed(words, passphrase="")
Given the word list, calculate original entropy:
entropy = mnemo.to_entropy(words)
