How to generate random AWS-like access key / secret key in Python

Typically, AWS access keys have a length of 20 characters from the following set: ABCDEFGHIJKLMNOPQRSTUVWXYZ234567 (also called uppercase base32 encoding)

The following Python code can be used to generate random AWS-like access keys & secret keys:

import base64
import secrets

def generate_random_base32_key(length=20):
    """
    Generate a random uppercase base32 string of the given length.
    """
    bytes_length = (length * 5) // 8
    random_bytes = secrets.token_bytes(bytes_length)
    base32_string = base64.b32encode(random_bytes).decode()[:length]
    return base32_string.upper()

# Usage example
random_access_key = generate_random_base32_key(20)
print(random_access_key)
