# How to generate Hash160 from a private key with the Bitcoin module

(Asked by: username_0 on 2020-09-11)

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:
https://github.com/primal100/pybitcointools/blob/master/cryptos/main.py
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
'34030ce14e32ac982419b3683af3b59d64a29cc93798cf479d610af49d425d13'
>>> pubkey = pybitcointools.privtopub (privkey)
>>> pubkey
'04ce0ed35340803b0c21f2f7f5d5ab9d687e5fa95a79471c9b5c9d97a0bb170eac1045230cc51d13b85a5f64feb80f8fc19358a396797926e3f89d49066b1abc07'

>>> addr = pybitcointools.hex_to_b58check (h160)
>>> addr
'12wsYc4B9c9JeREqstLZXNWa3n4i42M5jg'

Unfortunately I could not get from
 priv = random_key ()  --- > Hash160

How to do it?

I find the Bit module the easiest and most straight forward, albeit a tad, limited but with bit you can simply:
from bit import Key

# To generate private key
privKey= Key()

# Create Ripemd-160 Hash (address)
privKey.address

# or 

myAddress = privKey.address

# Segwit

MySegwitAddress = privKey.segwit_address


You can also import your own existing private keys like so:

# For wif format:
privKey = Key.('L1VotKmtZRLZSnSPhLhQxfts2aqBMru2APTs4Yuc8TYJ4jNhQoGB')

# For hex format:

privKey = Key.from_hex('ccb8c423403f4d5b6cde505d2a8f39d1d9399f6e06853339f5b11593cc502dc9')

# For int format:

privKey = Key.from_int('92598274663553697917256765988661195316245391320286084491562671024534692310473')

# For bytes format
privKey = Key.from_der(b'\xcc\xb8\xc4#@?M[l\xdeP]*\x8f9\xd1\xd99\x9fn\x06\x8539\xf5\xb1\x15\x93\xccP-\xc9)


Exporting works pretty much the same way as importing except you replace from.[format here] with to.[format here], you can even import or export a PEM file of your private key.
The documentation is enough for the library to give you the core functions, but is also somewhat lacking, for example you can't create compressed bitcoin addresses. But otherwise you can sign, send transactions, even select exactly which outputs you want to use .etc
