Java HDKeyDerivation Examples

Example #1

File: SimpleHDKeyChainTest.java Project: UberPay/-btctipme-gratuity-wallet

  @Before
  public void setup() {
    BriefLogFormatter.init();

    DeterministicSeed seed = new DeterministicSeed(ENTROPY, "", 0);
    masterKey = HDKeyDerivation.createMasterPrivateKey(seed.getSeedBytes());
    DeterministicHierarchy hierarchy = new DeterministicHierarchy(masterKey);
    DeterministicKey rootKey =
        hierarchy.get(ImmutableList.of(ChildNumber.ZERO_HARDENED), false, true);
    chain = new SimpleHDKeyChain(rootKey);
    chain.setLookaheadSize(10);
  }

Example #2

File: Bitcoin.java Project: RCasatta/EternityWallAndroid

  public static DeterministicKey keyFromMnemonic(String mnemonic) {
    final byte[] mySeed = getSeedFromPassphrase(mnemonic);
    final DeterministicKey deterministicKey = HDKeyDerivation.createMasterPrivateKey(mySeed);

    return deterministicKey;
  }

Example #3

File: DeterministicSigningKey.java Project: SKAPUSTIANSKYI/GreenBits

 @Override
 public ISigningWallet deriveChildKey(final ChildNumber childNumber) {
   return new DeterministicSigningKey(HDKeyDerivation.deriveChildKey(hdWallet, childNumber));
 }
