npm i @rsksmart/rif-id-mnemonic

Features

• BIP-39 complaint random mnemonic key generation given sentence size
• BIP-39 mnemonic to BIP-32 seed
• BIP-32 seed to BIP-44 compliant RSK multi-account base HD Key

Usage

Generate a mnemonic:

import { generateMnemonic } from '@rsksmart/rif-id-mnemonic'

const mnemonic = generateMnemonic(12)

Get a private key:

import { mnemonicToSeed, seedToRSKHDKey } from '@rsksmart/rif-id-mnemonic'

const seed = await mnemonicToSeed(mnemonic)
const hdKey = seedToRSKHDKey(seed)
const privateKey = hdKey.derive(0).privateKey?.toString('hex')

Or sync:

import { mnemonicToSeedSync, seedToRSKHDKey } from '@rsksmart/rif-id-mnemonic'

const seed = mnemonicToSeedSync(mnemonic)
const hdKey = seedToRSKHDKey(seed)
const privateKey = hdKey.derive(0).privateKey?.toString('hex')

Test

From base repo directory run npm test or any of the described test script variants.
