• A List<int> containing the derived HD path key.

Implementation

List<int> get hdPathKey {
  final hdPath = QuickCrypto.pbkdf2DeriveKey(
      password: List<int>.from([
        ...bip32.publicKey.compressed.sublist(1),
        ...bip32.chainCode.toBytes()
      ]),
      salt: StringUtils.encode(CardanoByronLegacyConst.hdPathKeyPbkdf2Salt),
      dklen: CardanoByronLegacyConst.hdPathKeyPbkdf2OutByteLen,
      iterations: CardanoByronLegacyConst.hdPathKeyPbkdf2Rounds);
  return hdPath;
