how to convert xprv to wif or (hex) 1,2,3 address index (python)

i try this script?

https://github.com/lyndsysimon/bip32utils

k.txt :

Code:

xprv9u4S6TaiPQdMnT6uRJXQCxW69c3dRK7QEWJzq8iTFGXi1RcfjomN1H13dvci2wLBhQYkYEk4GngfpL1F9fbBqcWWu6qWRPQbuR5wmHLgRm4

...

I want to use this command to select xprv  one by one and convert to wif or privkey(hex)

cat k.txt |  bip32gen  -i xprv -f - -o wif -F -  0 1

Code:

But it only works if there are only 1 xprv in the dictionary  / please help me how to make it possible to convert many

maybe some other similar script or this one like that?

I tried to search and it seems there is no direct guide to making a python script to bulk convert xprv to wif key or hex.

Why not try to play with this python that I found on Github.

Just take note only run this offline I do not know if this one is safe I just found it on Google when I search for a guide. Or you can get some idea there and build your own python script,.

You can make a wrapper script around bip32gen, in a single file using `os.spawnl` to create a bip32gen subprocess and wait for it to exit. The wrapper will just read the list of keys from a file and loop through them.
Note: Make sure you make the script wrapper executable.

Code:

#!/usr/bin/python3
import os

keys = []
file = open('keys.txt' 'r')
for l in file:
    keys.append(l.strip('\n'))
for k in keys:
    os.spawnl(os.P_WAIT, '/path/to/bip32gen', ['cmd', 'options', 'as', 'list'])

I did through bash as advised odolvlobo
but it turned out the speed is very low 23 xprv per second and I have a dictionary for 1 million xprv

anyway thank you for checking
