I have the following code in ruby:

hex = Digest::SHA1.hexdigest(str).to_i(16)
hex.to_s(32)

And I tried to implement it in python:

import hashlib
import base64

base64.b32encode(hashlib.sha1(str).digest())

When I run the code for the string test in ruby I get l558vpecm6dqc72c11pt74f9guc2veuj While in python I get VFFI7ZOMWGN2MHCMBBZ5HEPJQ6MC7O6T What is wrong with the python code? How to get the same results as for ruby?

    What are the conversions supposed to do? Also, did you check that the string results from the digest operation match, in the first place? – Karl Knechtel Jul 08 '20 at 08:32

    I don't know Python, but to get the Python result in Ruby, you can use the [base32](https://github.com/stesla/base32) gem: `Base32.encode(Digest::SHA1.digest('test'))`. Maybe that helps to find your problem. – Stefan Jul 08 '20 at 08:57
  • @KarlKnechtel We already have the ruby implementation - we use the results as identifier. Now I need to implement it in new service with python. And yes I did check the digest itself match. – Efrat Zelikovitz Jul 08 '20 at 09:20

    One version uses `digest`; the other uses `hexdigest`? – Tom Lord Jul 08 '20 at 11:22

Using gmpy:

import hashlib
import gmpy2

str = 'test'
h = hashlib.sha1(str).hexdigest()
i = int(h, 16)
gmpy2.digits(i, 32)
=> 'l558vpecm6dqc72c11pt74f9guc2veuj'

If you don't want to use gmpy and need a native Python version of digits, then you can find several implementations among the answers here.

I hope this could help you you will find Hashing examples in different languages: ruby, python, Go,...: https://gist.github.com/jasny/2200f68f8109b22e61863466374a5c1d
