dart-bitcoin / bip32-dart Goto Github PK

Hi,

I have the following code:

final mnemonic = bip39.generateMnemonic();
final seed = bip39.mnemonicToSeed(mnemonic);
final root = bip32.BIP32.fromSeed(seed); // error: Private key not in range [1, n] since pointycastle 2.0

Line three throws an error Private key not in range [1, n]

The same code seems to work well when overriding dependencies with an old pointycastle version:

dependency_overrides:
  pointycastle: ^1.0.2

Thank you.

When deriving an xpub I have the error Missing private key for hardened child key. Aren't you supposed to be able to derive with only the public key, for watch only wallets for example ?

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

void main(List<String> arguments) {
  final base58 = 'xpub661MyMwAqRbcFxtSX21UXfaDwmdN5zmJ1C8t1cjviNkkW6gXCd7AcfciXRuhPerjhnpziEXb2fsWkAVsNEJhgM5BPgnenuDDXVPbJSadrUG';
  final node = bip32.BIP32.fromBase58(base58);
  final derived = node.derivePath("m/44'/0'/0'/0/0");
  }

why don't work NetworkType

into codes used NetworkType that can as argument gave to this code 'bip32.BIP32.fromSeed(seed)' and with not giving this argument, bitcoin network is default but at all no matter and dont work!!!

Hello, would it be possible to publish on pub.dev the changes made with this pr #3?
We have developed a package based on these libraries, but the address derivation is wrong because there is no pull request fix.
Thanks

I‘ve got an error when using function sign(hash, x) which is import 'package:bip32/src/utils/ecurve.dart' as ecc;

var key = '8c39fb3d889b6be22850254dc7ce3247c559d9f968785d88251ee4457633e335';
var msg = '6ad99bc30926fd79cf5a977044088fd298a59728c5b0c1040713d3a8e1c1e69b';

var sig = sign(Uint8List.fromList(HEX.decode(msg)), Uint8List.fromList(HEX.decode(key)));

The expected sig is 00349f1a2df670db4ec676674489f12684afb0ca8225e02a1299c01b8c9c99804837d43fce2267e2200526f0ad304360a5371f859698c2a1c042004c85f1c985

But it throw an error:

Unhandled exception:
Bad state: Too few elements
#0      _TypedIntListMixin.setRange (dart:typed_data-patch/typed_data_patch.dart:408:7)
#1      sign (package:bip32/src/utils/ecurve.dart:134:10)
#2      sign (file:///D:/intchains/TEST/wallet/sign.dart:104:10)
#3      main (file:///D:/intchains/TEST/wallet/sign.dart:94:13)
#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:168:12)

I just found it’s because the length of encodeBigInt(sig.r) is 31, but buffer.setRange(0, 32, list) need 32.
If the result encodeBigInt(sig.r) can be length 32 with 0 fixed in the front of the list, it will be right.

I hope this problem can be fixed.

Hi

into codes used negativeFlag, In the event that not implement or declare for that !!!!

bip32-1.0.10/lib/src/utils/ecurve.dart:236:74: Error: Getter not found: 'negativeFlag'.
needsPaddingByte = ((number >> (rawSize - 1) * 8) & negativeFlag) == negativeFlag ? 1 : 0;

I want to use bip32 and the newest version of the pointycastle library.
But since bip32 depends on an older version of pointycastle, it would be awesome if you could update the used version.

expected value verified both using bitcoinjs/bip32 as well as bip32.org.

Looks like the derivation is skipping to the next index due to the check in bip_base.dart#109

Deriving m/1'/199007533'/627785449'/1521366139' produces the correct result so only the last segment causes the issue.

Test code:

  test('bug', () {
    final hd = BIP32.fromBase58('xprv9s21ZrQH143K3Jpuz63XbuGs9CH9xG4sniVBBRVm6AJR57D9arxWz6FkXF3JSxSK7jUmVA11AdWa6ZsUtwGztE4QT5i8Y457RRPvMCc39rY');
    final d = hd.derivePath("m/1'/199007533'/627785449'/1521366139'/1'");
    expect(d.toBase58(), 'xprvA39a1i4ieYqGUQ7G1KGnaGzGwm7v3emjms3QN4jZ3HPeubXjshA3XjD5XFaiNgWFvoyC2NV5jN4eFcsVhkrWkvwR4qjdPbue3kpt6Ur3JRf');
  });

Hi,

when will the null safety version be available?
