Whats the simplest and safest method to generate a API KEY and SECRET in Python
you can also use following module to generate random string
1 - os.urandom(64).encode('hex') #from os module
2 - uuid.uuid4() # from uuid module
3 - get_random_string(length=32) #from django.utils.crypto
4 - secrets.token_hex(64) #from secrets >= python 3.6
If you're on Python 3.6 or later, the secrets module is the way to go:
The secrets module is used for generating cryptographically strong random numbers suitable for managing data such as passwords, account authentication, security tokens, and related secrets.
In particular, secrets should be used in preference to the default pseudo-random number generator in the random module, which is designed for modelling and simulation, not security or cryptography.
e.g. to generate a 16 byte token:
>>> import secrets
>>> secrets.token_urlsafe(16)
'zs9XYCbTPKvux46UJckflw'
>>> secrets.token_hex(16)
'6bef18936ac12a9096e9fe7a8fe1f777'
For python3.6+
import secrets
generated_key = secrets.token_urlsafe(length)
For older versions of python:
for a very secure way of generating random number, you should use urandom:
from binascii import hexlify
key = hexlify(os.urandom(length))
this will produce bytes, call key.decode()
if you need a string
For general non-secure random strings, with more settings, you can just generate keys of your desired length the python way:
import random
import string
def generate_key(length):
return ''.join(random.choice(string.ascii_letters + string.digits) for _ in range(length))
And then you can just call it with your desired length key = generate_key(40)
.
You can specify what alphabet you want to use, for example using only string.ascii_lowercase
for key consisting of only lowercase letters etc.
