"Kluchnik" Client Application

This is the repository for the desktop client application that interacts with the "Kluchnik" hardware True Random Number Generator (TRNG). The application is written in Rust using the cross-platform Iced GUI framework.

✨ Features

• Wi-Fi Connection: Automatically connects to the access point created by the "Kluchnik" device.
• Secure Data Transfer: Receives an encrypted 128-bit key over the TCP protocol.
• Decryption: Uses the AES-128-CBC standard to decrypt the key, ensuring its integrity.
• Password Generation: Creates cryptographically strong passwords based on the truly random data.
• Visualization: Displays the generated password and a QR code for easy use on mobile devices.
• Remote Control: Allows you to control the device's menu using buttons in the interface or keyboard hotkeys (arrow keys, Enter, Space).
• Customization: Supports light and dark UI themes.

🖥️ System Requirements

• Operating System: Linux (primary target), Windows, macOS.
• Build Dependencies (Linux): To compile on Debian/Ubuntu-based distributions, you may need to install development packages:

  sudo apt-get install build-essential libgtk-3-dev libxcb-shape0-dev libxcb-xfixes0-dev

🛠️ Build and Run

1. Install Rust

If you don't have Rust installed, use the official installer:

curl --proto '=https' --tlsv1.2 -sSf [https://sh.rustup.rs](https://sh.rustup.rs) | sh

2. Clone and Setup

git clone [https://github.com/your-repo/kluchnik-rs.git](https://github.com/your-repo/kluchnik-rs.git)
cd kluchnik-rs

Important: For the interface to display correctly, place the following files in the root folder of the project (next to Cargo.toml):

• logo.svg — your logo in SVG format.
• GeistMono-Regular.otf — the custom font file.

3. Run in Development Mode

cargo run

4. Build for Distribution

To compile an optimized version of the application, run:

cargo build --release

The final executable file will be located in the target/release/ directory.

🚀 Distribution

To distribute the application to users:

1. Create a new folder.
2. Copy the executable file from target/release/ into it.
3. Copy the logo.svg and GeistMono-Regular.otf files into the same folder.
4. Archive the folder and send it to the user.

The application is now ready to run!
