OTP Generator (ft_otp)

This project is a tool that allows users to securely generate OTP (One Time Password). It can work with both command-line interface and graphical user interface (GUI). This tool generates OTPs that can be especially used for two-factor authentication (2FA).

Getting Started

You can follow these steps to start using this project:

git clone https://github.com/whymami/ft_otp.git && cd ft_otp

python main.py -g <path>

This command will take a key from the file you provided and save it encrypted to ft_otp.key file.

2. Generate OTP

To print the password using an existing OTP key:

python main.py -k <key_file>

3. GUI Usage

To run the project in GUI mode:

python main.py -G gui

In the GUI, users can:

• Enter OTP keys
• Select key from file
• View OTP
• Generate QR code
