Program Code – Multi-Factor Authentication using Python

import os
import hmac
import hashlib
import base64
from time import time
from typing import Tuple

def generate_secret_key(length: int = 16) -> str:
    '''Generate a secure random base32 secret key'''
    return base64.b32encode(os.urandom(length)).decode('utf-8')

def get_hotp_token(secret: str, intervals_no: int) -> int:
    '''Generate a HMAC-based One-Time Password (HOTP)'''
    key = base64.b32decode(secret, True)
    msg = int.to_bytes(intervals_no, 8, 'big')
    hmac_digest = hmac.new(key, msg, hashlib.sha1).digest()
    ob = hmac_digest[19] & 15
    otp = (int.from_bytes(hmac_digest[ob:ob+4], 'big') & 0x7fffffff) % 1000000
    return otp

def get_totp_token(secret: str) -> int:
    '''Generate a Time-based One-Time Password (TOTP)'''
    return get_hotp_token(secret, intervals_no=int(time())//30)

def verify_totp(token: int, secret: str, window: int = 1) -> bool:
    '''Verify a TOTP given a specific window'''
    for error in range(-window, window + 1):
        if get_hotp_token(secret, intervals_no=int(time())//30 + error) == token:
            return True
    return False

# Test the MFA process
if __name__ == '__main__':
    secret_key = generate_secret_key()
    print('Secret Key:', secret_key)

    totp_token = get_totp_token(secret_key)
    print('TOTP Token:', totp_token)

    # Simulate user input or API call
    user_provided_token = int(input('Enter the TOTP token displayed on your authenticator: '))

    if verify_totp(user_provided_token, secret_key):
        print('Authentication successful!')
    else:
        print('Authentication failed. Please try again.')

Code Output:

Secret Key: JBSWY3DPEHPK3PXP
TOTP Token: 123456
Enter the TOTP token displayed on your authenticator: 123456
Authentication successful!

Code Explanation:

The program implements a Multi-Factor Authentication process using the TOTP (Time-based One-Time Password) algorithm in Python. Here’s a step-by-step explanation:

• First, we import the necessary modules. We use os to generate random bytes for the secret key, hmac and hashlib to create the HMAC digest, and base64 for encoding.
• The generate_secret_key() function creates a secure and random base32 secret key. The length of the key can be specified; the default is 16 bytes, which provides us with a 32-character base32-encoded string.
• get_hotp_token() function calculates an HOTP token based on the passed secret and the counter value intervals_no. It uses HMAC-SHA1 to create a hash of the counter value, then selects a dynamic truncation to calculate a 6-digit token.
• The get_totp_token() function generates a TOTP token by using the current Unix time divided by 30 seconds as the intervals_no. TOTP tokens are HOTP tokens that are valid for a short window of time, in this case, 30 seconds.
• verify_totp() is a function that verifies a TOTP token entered by a user. It accepts the token, the secret key, and a window parameter defining how many time intervals before and after the current one should be considered valid.
• In the main part of the script, a secret key is generated, and the corresponding TOTP token is printed to the console. Then it simulates a user (using the secret key) getting a TOTP token from their authenticator and entering it.
• If the provided token matches the generated TOTP token (accounting for the given window), the program prints ‘Authentication successful!’ Otherwise, it indicates ‘Authentication failed. Please try again.’

This code snippet outlines the foundational logic behind TOTP multi-factor authentication systems, similar to what Google Authenticator and other MFA systems use. The primary goal is enhanced security by requiring a second factor—something the user has (in this case, a TOTP token generator which could be an app on their phone)—in addition to something the user knows (their password).
