How to generate a secret key with Python

# How to generate a secret key with Python

import os
os.urandom(24)

In python3.6 secrets module can be used to generate secrets.

>>> secrets.token_hex(16)  
'f9bf78b9a18ce6d46a0cd2b0b86df9da'

Example taken from the official documentation on secrets module.

Can the secrets module be installed in python 2.x?

@csolorio I checked for a backport of Python 3.6 stdlib secrets and I couldn't find one. But if you look at cpython/secrets.py you may find it's a small enough module to backport on your own for your project. (Or just implement and test the same gist yourself.)

Hello

and the following is my setting .py

mport os

os_env = os.environ

class Config(object):
SECRET_KEY = os_env['SOLARPI_SECRET']
APP_DIR = os.path.abspath(os.path.dirname(file)) # This directory

class TestConfig(Config):

BCRYPT_LOG_ROUNDS = 1 # For faster tests
WTF_CSRF_ENABLED = False # Allows form testing

any idea how i can solve this

For Python 2.X and Python 3.X

>>> import binascii
>>> binascii.hexlify(os.urandom(24))
b'0ccd512f8c3493797a23557c32db38e7d51ed74f14fa7580'

Did you get any solution for this. I too facing the same issue
