Generate SHA512-CRYPT with Python 3

generate_sha512-crypt.py

#!/usr/bin/env python3
import os
import secrets
import passlib.hash
import sys

def generateHash(password, salt_len=10, iterations=65000):
  result = passlib.hash.sha512_crypt(salt=secrets.token_hex(salt_len), rounds=iterations).hash(password)
  return '{SHA512-CRYPT}' + result

user_input = sys.argv[1]
print(generateHash(user_input))

Hello, thank you for a good example. But you should use sha512_crypt.using() function if you want to change iterations number

passlib.hash.sha512_crypt.using(salt=secrets.token_hex(salt_len), rounds=iterations).hash(password)
