I have used the Random library in Python a few times to generate a random choice; however many people will (rightly) tell you that a computer generated random number is not a true random number.
The Random library is perfect for games or simulations that do not require security (cryptography); however for Python projects that do need security (e.g. security keys) then there is a Python library called Secrets.
I’ve had a brief play with Secrets; originally as I stumbled across the secrets.randbelow(n) –with n begins a integer– command, which soon lead to me playing with the secrets.randbits(k) –with k being a integer– command
# geektechstuff # ssshhh, it is a secret import secrets #imports secrets library import random #imports random library - not really needed, but I wanted to see random and secret working alongside each other test_range = random.randint(0, 999) test_below = secrets.randbelow(1000) print('rand', test_range) print('sec', test_below) test_32bits = secrets.randbits(32) test_64bits = secrets.randbits(64) test_128bits = secrets.randbits(128) test_256bits = secrets.randbits(256) test_512bits = secrets.randbits(512) print(test_32bits) print('') print(test_64bits) print('') print(test_128bits) print('') print(test_256bits) print('') print(test_512bits) print('')
256 bit encryption is used for most modern encryption methods (such as SSL and AES) and in theory it would take 50 supercomputers checking a billion billion (thats 1018) keys around 3×1051 years to break according to Wikipedia.
I’m thinking I might be able to use the Secrets library in a crypto / cipher project…
