2. Install requirements:

   pip install -r requirements

3. Use library:

   from hdtools.extended_keys import *
   private_key = XPrv.from_mnemonic('mnemonic phrase')
   private_key.encode() 

How to install

pip install hdtools

Examples

hdtools's Issues

Implement BIP32

We must implement bip32 based on:

docs for noobs

Hi,
for newb like me, it will be great if there's more document on how to use your lib. for example, how to use it on testnet?

How to sign transactions

Hi,

I'm having trouble trying to understand how to use the extended_keys after I derived them using hdtools.
I generated my address in a similar way as the one you described in the README:
xprv = (m/44./0./0./0/0)
address = xprv.address()

I sent some BTC on a private regtest chain to this address and now I would like to understand how to send them back using hdtools.

Usually I would do this by creating a rawtransaction and signing it with the private key derived by the Bip39 online tool.

Is there a way to either retrieve the private key that can be used to sign a transaction from this address or, even better, directlly sign the transaction using xprv ?
