go-bip39

A golang implementation of the BIP0039 spec for mnemonic seeds

Fork

This is a fork of github.com/tyler-smith/go-bip39 from right after the fixes from bartekn for MnemonicToByteArray were merged (commit hash: 52158e4697b87de16ed390e1bdaf813e581008fa).

The tyler-smith repo is undergoing significant refactoring at present that we may not want (eg. some vars becoming private).

English wordlist and test vectors are from the standard Python BIP0039 implementation from the Trezor guys: https://github.com/trezor/python-mnemonic

Example

package main

import (
  "github.com/tyler-smith/go-bip39"
  "github.com/tyler-smith/go-bip32"
  "fmt"
)

func main(){
  // Generate a mnemonic for memorization or user-friendly seeds
  entropy, _ := bip39.NewEntropy(256)
  mnemonic, _ := bip39.NewMnemonic(entropy)

  // Generate a Bip32 HD wallet for the mnemonic and a user supplied password
  seed := bip39.NewSeed(mnemonic, "Secret Passphrase")

  masterKey, _ := bip32.NewMasterKey(seed)
  publicKey := masterKey.PublicKey()

  // Display mnemonic and keys
  fmt.Println("Mnemonic: ", mnemonic)
  fmt.Println("Master private key: ", masterKey)
  fmt.Println("Master public key: ", publicKey)
}
