T2fa - Simple and Easy-to-Use TOTP Generator

T2fa is a lightweight and easy-to-use Time-Based One-Time Password (TOTP) generator. This library is perfect for developers who need to integrate TOTP functionality into their tools, whether for authentication or security-related applications. With T2fa, you can easily generate TOTP tokens for use in requests-based tools, APIs, and many other applications that require secure one-time passwords.

Features

• Easy Integration: T2fa allows for simple integration with your Python projects.
• Multiple Algorithm Support: Supports SHA-1, SHA-256, and SHA-512 algorithms for TOTP generation.
• Flexible: Customize the number of digits and time intervals for OTP generation.
• Cross-Platform: Works on all major platforms where Python is supported.
• Secure: Implements TOTP as per RFC 6238, ensuring the highest level of security.

Installation

Using pip

You can easily install T2fa via pip, Python's package manager. Simply run the following command:

pip install T2fa

Manual Installation

1. Clone the repository:

   git clone https://github.com/AxZeRxD/T2fa.git
   cd T2fa

2. Install dependencies:

   pip install -r requirements.txt

3. (Optional) You can now manually run the tests or use the tool in your project.

Usage

Importing T2fa

To get started, you first need to import the Totp class from the package:

from T2fa import Totp

Example Usage

# Example of generating and verifying OTP
secret = "khxi okcj zqtc j54b 2t2x awcr xx3x g5ln"  # Secret key used for TOTP generation

# Initialize the TOTP object for SHA-1 algorithm
pyauth_sha1 = Totp.gen(secret=secret, algorithm="SHA1", digits=6, interval=30)

# Generate OTP
otp_sha1 = pyauth_sha1.genotp()
print(f"Generated OTP (SHA1): {otp_sha1}")

# Verify OTP
if pyauth_sha1.verifyotp(otp_sha1):
    print(f"OTP (SHA1) is valid.")
else:
    print(f"OTP (SHA1) is invalid.")

Supported Algorithms

• SHA-1: Default algorithm for TOTP generation.
• SHA-256: A more secure option with a longer hash length.
• SHA-512: Provides even higher security and longer hash length.

You can switch between these algorithms using the algorithm parameter when creating a TOTP instance.

Configuration

You can configure various aspects of the OTP generation:

• digits: Number of digits in the OTP (default is 6).
• interval: The time window for OTP validity in seconds (default is 30 seconds).
• algorithm: The hashing algorithm to use for OTP generation (options: "SHA1", "SHA256", "SHA512").

Example for Customization

# Custom configuration for SHA-256 with a 8-digit OTP and 60-second interval
pyauth_sha256 = Totp.gen(secret=secret, algorithm="SHA256", digits=8, interval=60)
otp_sha256 = pyauth_sha256.genotp()
print(f"Generated OTP (SHA256): {otp_sha256}")

Testing

You can run tests to ensure that everything works as expected. If you're using pytest or another test runner, you can run:

python pytest

Or simply run your Python script to check if TOTP generation and verification are working properly.
