Generate, recover IOTA seed from Bitcoin BIP39 mnemonic

Project description

IOTA Mnemonic

This is a command line tool to help user generate IOTA seed from Bitcoin BIP39 mnenomics

Install

$ pipenv install iota_mnemonic

To install IOTA mnemonic, simply run this simple command in your terminal of choice:

$ pipenv install iota_mnemonic

Get the source code

You can clone the source code from repository:

How it works?

To create IOTA seed from the mnemonic, we use IOTA Kerl function with a mnemonic sentence (in UTF-8 NFKD) used as the password and the string “mnemonic” + passphrase (again in UTF-8 NFKD) used as the salt.

To get a valid tryte hash, we concat salt and mnemonic sentence, and load into iota.Hash by from_string function. from_string will encode UTF-8 NFKD into bytes, then convert bytes into IOTA hash.

Using each hash, we then use hash trits and Kerl to absorb and squeeze:

trits = []
sponge = iota.crypto.kerl.Kerl()

for word in mnemonic:
    hash = iota.Hash.from_string(f'mnemonic{passphrase}{word}')
    hash_trits = hash.as_trits()
    k = iota.crypto.kerl.Kerl()
    k.absorb(hash_trits)
    k.squeeze(hash_trits)
    sponge.absorb(hash_trits)
sponge.squeeze(trits)
return iota.Hash.from_trits(trits)
