btclib's Issues

Help wanted: Creating a list of derived addresses from a xPub string

Hey,

I'm just starting out with Python, so I'm not sure how to accomplish this:

For example, I would have string key = 'zpub6rLtzSoXnXKPXHroRKGCwuRVHjgA5YL6oUkdZnCfbDLdtAKNXb1FX1EmPUYR1uYMRBpngvkdJwxqhLvM46trRy5MRb7oYdSLbb4w5VC4i3z'

How would I make the btclib package return a list like this?

1: bc1q360p67y3jvards9f2eud5rlu07q8ampfp35vp7
2: bc1qs4k3p9w4ke5np3lr3lgnma9jcaxedau8mpwawu
3: bc1qpk48z0s7gvyrupm2wmd7nr0fdzkxa42372ver2

Any help would be appreciated. Thanks! :-)

b58 package missing

Hello, I installed the package via pip but when I want to use the b58 module like
from btclib import b58
I got the following error:
ImportError: cannot import name 'b58' from 'btclib' (/usr/local/lib/python3.9/site-packages/btclib/__init__.py)

Checking the packages shows that indeed it is not present

Any ideas what is wrong or how can I get that module installed?

How could we restore the private key from extended private key in bip32.py

There is a function address_from_xpub to generate the address from xpub.
Could we have a key_from_xprv to generate the private key from xprv in bip32.py as well?

Re-import Tx subclasses into btclib.tx

It should be possible to write:

from btclib.tx import Tx, TxIn, TxOut

instead of manually importing each from btclib.tx.tx_whatever.

Error that no btclib module

Hello,
Your code looks useful. However, I've installed the btclib under the python 3.6.5 and all went well with installation but when I try to run some of the files I get errors that there is no btclib module.

For beginners, more specific documentation can be created.

I hope to create a detailed example document to help beginners learn BTC better.
For example, sending transactions, deriving wallets, etc.

    !!


    ############################
    # Package would be ignored #
    ############################
    Python recognizes 'btclib.mnemonic._data' as an importable package,
    but it is not listed in the `packages` configuration of setuptools.

    'btclib.mnemonic._data' has been automatically added to the distribution only
    because it may contain data files, but this behavior is likely to change
    in future versions of setuptools (and therefore is considered deprecated).

    Please make sure that 'btclib.mnemonic._data' is included as a package by using
    the `packages` configuration field or the proper discovery methods
    (for example by using `find_namespace_packages(...)`/`find_namespace:`
    instead of `find_packages(...)`/`find:`).

    You can read more about "package discovery" and "data files" on setuptools
    documentation page.

Valid taproot signature may not must has length of 64

Describe the bug
It seems not right to check signature of taproot is valid by assert length of it equals 64:

btclib/btclib/psbt/psbt_utils.py

Line 307 in da0cfc1

if any(signature and len(signature) != 64 for signature in signatures):

To Reproduce
There is an example on how to make a valid taproot signature which length is not 64:
bitcoinjs/bitcoinjs-lib#1934

Environment (please complete the following information):

OS: ubuntu
Python version: 3.10.13
btclib version: da0cfc1 master 2023.12.12
