BIP39

Fork of JavaScript implementation of Bitcoin BIP39 using node.js crypto library. And loading only the English word list by default.

Examples

var bip39 = require('bip39crypto')

// Generate a random mnemonic (uses crypto.randomBytes under the hood), defaults to 128-bits of entropy
var mnemonic = bip39.generateMnemonic()
// => 'seed sock milk update focus rotate barely fade car face mechanic mercy'

bip39.mnemonicToSeedHex('basket actual')
// => '5cf2d4a8b0355e90295bdfc565a022a409af063d5365bb57bf74d9528f494bfa4400f53d8349b80fdae44082d7f9541e1dba2b003bcfec9d0d53781ca676651f'

bip39.mnemonicToSeed('basket actual')
// => <Buffer 5c f2 d4 a8 b0 35 5e 90 29 5b df c5 65 a0 22 a4 09 af 06 3d 53 65 bb 57 bf 74 d9 52 8f 49 4b fa 44 00 f5 3d 83 49 b8 0f da e4 40 82 d7 f9 54 1e 1d ba 2b ...>

bip39.validateMnemonic(mnemonic)
// => true

bip39.validateMnemonic('basket actual')
// => false

var bip39 = require('bip39crypto')

// defaults to BIP39 English word list
// uses HEX strings for entropy
var mnemonic = bip39.entropyToMnemonic('00000000000000000000000000000000')
// => abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon abandon about

bip39.mnemonicToEntropy(mnemonic)
