How to get private key from ethereum wallet?

[zaza316614]

This package is good to me. Using this package, I generated ethereum wallet. Here, private key is as follow. 0488ade4039c7ed931800000009f85cde1810467f199d7e0b6b2edaa6bc2f960b66ea61af9e35477c50e2243da00494c713bd615f7bef54adca9292cbd86e9f077e6a0ee33553258a2d961793a4e

But when I send transaction using web3.py, required private key has 32 bytes long. Above key is too long. I can't use this. How can I get private key to be required to send transaction? Help me.

I spent a while looking through the code and I also couldn't figure out...

Had the same issue, install this library and use the code below to get the actual private key:

from crypto import HDPrivateKey, HDKey, PrivateKey


def decode(pkey_hex):
    assert len(pkey_hex) == 156
    pkey = HDPrivateKey.from_hex(pkey_hex)
    keys = HDKey.from_path(pkey, '{change}/{index}'.format(change=0, index=0))
    private_key = keys[-1]
    public_key = private_key.public_key
    print('  Private key (hex, compressed): 0x' + private_key._key.to_hex())
    print('  Address: ' + private_key.public_key.address())


def main():
    keys = [
        '0488ade4039c7ed931800000009f85cde1810467f199d7e0b6b2edaa6bc2f960b66ea61af9e35477c50e2243da00494c713bd615f7bef54adca9292cbd86e9f077e6a0ee33553258a2d961793a4e'
    ]
    for k in keys:
        decode(k)


if __name__ == '__main__':
    main()

Hi @henrytom1703, I used python 3.6, worked for me. Create new virtual environment, git clone this repo, run pip install -r requirements.txt then try again
