fixed for invalid derivation result for specific path #2

When do Uint8List dt = toBuffer((dd + tt) % n); It will happened the length of dt is smaller than 32. We have to make sure the length is always 32.

Could you help me add test to cover this code, Thanks!

import 'package:bip39/bip39.dart' as bip39; import 'package:bip32/bip32.dart' as bip32; import 'package:hex/hex.dart';

test() { const randomMnemonic = 'culture sound obey clean pretty medal churn behind chief cactus alley ready'; var seed = bip39.mnemonicToSeed(randomMnemonic); var root = bip32.BIP32.fromSeed(seed); var child = root.derivePath("m/44'/60'/0'/0/0"); var publicKey = HEX.encode(child.publicKey); print(publicKey); }

You can check it from https://iancoleman.io/bip39/. the publicKey should be 0x020c91d155e52b37d4d7d2c9127501a00a841acd8ef1d7b05f3079120df145da6a But the code shows 02cbdc25dcdde03ac8d2b3cf785d035ae86e99e662c26f99ab8ab6d0e5f3554e86
