JavaScript implementation of Bitcoin BIP39: Mnemonic code for generating deterministic keys

Usage

npm install bip39

var BIP39 = require('bip39')

var mnemonic = BIP39.entropyToMnemonic('1337') // hex input, defaults to BIP39 English word list
// 'basket actual'

// or
mnemonic = BIP39.generateMnemonic() // strength defaults to 128 bits
// 'seed sock milk update focus rotate barely fade car face mechanic mercy'

BIP39.mnemonicToSeedHex('basket actual') // wait for it...
// '5cf2d4a8b0355e90295bdfc565a022a409af063d5365bb57bf74d9528f494bfa4400f53d8349b80fdae44082d7f9541e1dba2b003bcfec9d0d53781ca676651f'
