bip32key

The implementation of Hierarchical Deterministic (HD) wallets generator for Ethereum blockchain

Installation

Install bip32key

pip install bip32key

Usage

Import entropy

from bip32key import BIP32KEY, BIP32KEY_HARDEN
import binascii

# Import entropy
entropy = binascii.hexlify(b"Meheret Tesfaye Batu")
master_key = BIP32KEY.fromEntropy(entropy)

Import Path

# Added master key path
master_key = master_key.fromPath("m/44'/69'/12'/5/0")

Or Import Index

# This is same with fromPath
master_key = master_key.fromIndex(44 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(69 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(12 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(5)
master_key = master_key.fromIndex(0)

Get All

# Get All Information
print(master_key.print())

# Get Address
print(master_key.address())
# Get Wallet Import Format
print(master_key.walletImportFormat())
# Get Finger Print
print(master_key.fingerPrint().hex())
# Get Chain Code
print(master_key.chainCode())
# Get Private Key
print(master_key.privateKey().hex())
# Get Public Key
print(master_key.publicKey().hex())

##### Serialized #####

# Get Private Key Hex
print(master_key.extendedKey(private=True, encoded=False).hex())
# Get Public Key Hex
print(master_key.extendedKey(private=False, encoded=False).hex())
# Get XPrivate Key Base58
print(master_key.extendedKey(private=True, encoded=True))
# Get XPublic Key Base58
print(master_key.extendedKey(private=False, encoded=True))

Example

Metamask and MyEtherWallet uses this path/index

master_key = master_key.fromPath("m/44'/60'/0'/0/0")

master_key = master_key.fromIndex(44 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(60 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(0 + BIP32KEY_HARDEN)
master_key = master_key.fromIndex(0)
master_key = master_key.fromIndex(0)
