:snake: Mnemonic code for generating deterministic keys, BIP39

Python-mnemonic

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

Please make sure that you have python 3.7 or higher.

To install this library and its dependencies use, run the following command in the current directory:

python setup.py install develop

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
• turkish
• czech
• portuguese

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="")
