This fork contains additional encryption methods to encrypt an existing mnemonic with a passwort to get a new encrypted mnemonic that is worthless without the password. But no observer could tell what the real wallet is.

BIP39 standard already allows you to create a seed from a mnemonic plus password. But that means, that you can not protect a mnemonic from an existing wallet (e.g. a mnemonic without password from a Trezor) with plausibel deniability.

Example

package main

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

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)
}
