I want to fix the script code. The script generates from a random private key Bitcoin Address by function (pubtoaddr) and works on the Bitcoin module:


from bitcoin import *
import os

    priv = random_key ()
    pub = privtopub (priv)
    addr = pubtoaddr (pub)


But I need to get from a Random Private Key in Hash160

For some reason I could not find such a function in main.py

I searched and found an article

>>> import pybitcointools
>>> privkey = pybitcointools.random_key ()
>>> privkey
>>> pubkey = pybitcointools.privtopub (privkey)
>>> pubkey
>>> h160 = pybitcointools.hash160 (pubkey.decode ('hex'))
>>> h160
>>> addr = pybitcointools.hex_to_b58check (h160)
>>> addr

Unfortunately I could not get from

 priv = random_key ()  --- > Hash160

How to do it?


I am using a different bitcoin library. This prints address and hash160 from a private key:

from bitcoinutils.setup import setup
from bitcoinutils.keys import P2pkhAddress, PrivateKey, PublicKey

def main():
    # setup the network

    # provide a private WIF key
    priv = PrivateKey.from_wif('cMahea7zqjxrtgAbB7LSGbcQUr1uX1ojuat9jZodMN87K7XCyj5v')

    # get the public key
    pub = priv.get_public_key()

    # get address from public key
    address = pub.get_address()

    # print address and hash160
    print("Address:", address.to_string())
    print("Hash160:", address.to_hash160())


if __name__ == "__main__":


For segwit addresses you can refer to this example: https://github.com/karask/python-bitcoin-utils/blob/master/examples/keys_segwit_addresses.py

  • I'll try to use this module! How to write a function in the code so that "PrivateKey" is generated in a random way? – Dmitry Bazhenovsky Sep 12 '20 at 5:12
  • Replace priv = PrivateKey.from_wif('cMahea7zqjxrtgAbB7LSGbcQUr1uX1ojuat9jZodMN87K7XCyj5v') with priv = PrivateKey() in the above code and also add a print statement below to see the new private key each time you run the code: print("Private Key:", priv.to_wif(compressed=True)) – Prayank Sep 12 '20 at 7:11

  • If you are asking about private key WIF, it's base58: learnmeabitcoin.com/technical/wif – Prayank Sep 12 '20 at 8:05
