This project is a simple command-line tool created as a school project using Rust. 🎓 It's designed to generate Time-based One-Time Passwords (TOTP) by encrypting a key and generating a QR code for TOTP app registration. 🕒

• Encrypt Key: 🔒 Securely encrypts a provided hex key and saves it for TOTP generation.
• Generate QR Code: 📱 Creates a QR code to easily add the encrypted key to a TOTP app.
• Generate TOTP: 🗝️ Produces a TOTP code using the encrypted key and current time.

• Rust Programming Language 🦀

To set up this project, follow these steps:

git clone <repository-url>
cd ft_otp
cargo build --release

Execute the program with options to encrypt a key, generate a QR code, or produce a TOTP code:

./target/release/ft_otp [OPTIONS]

• -g, --generate <path>: 🔐 Encrypt and save a hex key from a specified path.
• -q, --qrcode <file>: 🖼️ Specify the output file for the QR code (default qr.png).
• -k, --key <path>: 🗝️ Use an encrypted key file to generate the TOTP code (default ft_otp.key).

• To encrypt a key and generate a QR code:

  ./target/release/ft_otp --generate your_key_path --qrcode your_qr_code.png
  

• To generate a TOTP code:

  ./target/release/ft_otp --key your_encrypted_key_file
