Java implementation of the BIP 39 specification.

How to use

Create a new mnemonic (a seed phrase)

  Dictionary dictionary = EnglishDictionary.instance();

  Bip39 bip39 = new Bip39(dictionary);

  byte[] entropy = bip39.generateEntropy(EntropyDesc.ENT_128);

  String mnemonic = bip39.createMnemonic(entropy);

Convert a mnemonic to a seed

  String mnemonic = "legal winner thank year wave sausage worth useful legal winner thank yellow";
  String passphrase = "TREZOR";

  byte[] seed = bip39.createSeed(mnemonic, passphrase);
